World's 1st multimedia performance in microgravity will bring together Cirque du Soleil, National Geographic and NASA

Exotic entertainment will enter a whole new frontier of zero-gravity environment venues later this year when acclaimed multimedia artist and international showmaker Natasha Tsakos takes her acrobatic dance team into the wild blue yonder and beyond. This thrilling Paraboles multimedia performance, produced in association with the MIT Space Exploration Initiative and Zero-G, will gather a brave group of professionals from Cirque du Soleil, National Geographic and NASA to stage the uplifting event. As the space economy blossoms, Tsakos is aiming to deliver culturally relevant content into the expanding realm of aerospace innovation. "I'm a producer, director, designer, and performer and I create live multimedia theatrical shows," Tsakos told Space.com. "I integrated technology early on in the 2000s with projection mapping and leveraging CGI with the performers on stage before it was common. From there I got to open the G-20 Summit and create shows for the Discovery Channel and Tribeca Film Festival and worked with Cirque du Soleil and opened the Super Bowl. So I've been on this string of extraordinary experiences and throughout, my moonshot was always to create shows for space." Set aboard Zero-G's specially modified Boeing 727-200 dubbed "G-Force One," Paraboles will be presented and filmed along 25 gravity-defying parabolic arcs, with each segment promising 22 seconds of free-floating microgravity conditions. A trio of skilled performers and two cinematographers will work in multiple zero-G zones sometime this fall, recording the sublime poetry of motion in a transcendent environment unhindered by the earthly bounds of gravity. Tsakos was unsure of what that notion might evolve into as a reality, as she was enticed by the pure poetry of space as most dreamers and artists have fallen prey to. "So I enrolled in the New Space Economy course at MIT that allowed me to really create this bold, ambitious 100-year plan with no limits." she told Space.com. "Where we're envisioning our own international performance space station and the evolution of performing arts on the moon and Mars. Then we reverse engineered, and asked where do we start? We start aboard the Zero-G flights and we have to start training and developing new forms of theatrical art. I've always been interested in stretching the performing art form and going past the phase of experimentation." The result of this endeavor will be a cinematic art film, short documentary, and an immersive installation, which will premiere in 2026. Tsakos has engaged global audiences in the millions, from Miami to Montreux, with the goal of redefining live performances from high above Earth to the limits of imagination and possibility. Fortified with NASA funding, Tsakos has undergone astronautical training, including the Lunar-G Impedance Study at NASA's Johnson Space Center, Neutral Buoyancy training at NASA Ames, MIT's New Space Economy program, and NASA L'SPACE Academy in preparation for this spirited enterprise. "All the pieces are in place, the team is ready. At Pixar I've storyboarded all of the experience because it doesn't have language. I use movements, motion, music dynamics, and visuals to take you through this experience. Paraboles is a poetic, cinematic, dance theater, research-based experiment and it delves into the tension between holding on and letting go." "It follows three characters holding onto their stories, beliefs, and memories. We're leveraging the force of the hypergravity and microgravity as parts of the dramaturgy and the narrative to create this experience to be filmed aboard the Zero-G plane. Then all the beauty and the worldbuilding will happen in post-production." Paraboles was born two years ago and the group is scheduled to fly this fall with MIT's Space Exploration Initiative with Zero-G as a sponsor, in conjunction with local Miami cultural partners including Live Arts Miami, Miami Nights Project, and O Cinema, which is where the piece will premiere. Creativity America is also onboard as a national creative partner. On the educational and scientific fronts, they'll have the beginning of a training curriculum for artists who want to work in that environment. "We're also pairing our performance with science. We have a bio-astronautic officer who oversees payloads for Virgin Galactic and SpaceX and even the ISS and she will be tracking our biometrics so we’ll have some actual published research." Tsakos adds. "End of July or early August is when we'll start a 50-day intensive training regimen that I'm super excited about. We’ll be training in wind tunnels at iFLY here in Miami and underwater at the MDC Aquatic Center, and then aerobatic aircraft at the International Institute for Astronautical Sciences in Melbourne.” For more information on the Paraboles project visit their official site.

A spinning universe could crack the mysteries of dark energy and our place in the multiverse

What is dark energy? Why does dark energy seem to be weakening? Is our universe part of a larger multiverse? What lies beyond the boundary of a black hole? The universe seems to be rotating, and if that is the case, then this could have major ramifications for some of the biggest questions in science, including those above. That's according to Polish theoretical physicist Nikodem Poplawski of the University of New Haven, who is well-known for his theory that black holes act as doorways to other universes. "Dark energy is one of the most intriguing mysteries of the universe. Many researchers have tried to explain it by modifying equations of general relativity or suggesting the existence of new fields that could accelerate the universe's expansion," Poplawski told Space.com. "It would be amazing if a simple rotation of the universe was the origin of dark energy, especially that it predicts its weakening." Evidence that the universe is rotating was recently delivered by the James Webb Space Telescope (JWST), which found that two-thirds of galaxies are rotating in the same direction. This suggests a lack of randomness and a preferred direction for cosmic rotation. Additionally, Poplawski pointed out that other astronomical data seem to show that the angle between the most likely axis of the spinning galaxies and the axis of the bulk flow of nearby galaxy clusters is 98 degrees, meaning they are nearly perpendicular in relation to each other. That is something that is in accordance with the hypothesis that the universe is rotating. To understand why a rotating universe implies more than one universe, Poplawski refers to "frames of reference." These are sets of coordinate systems that are integral to physics, which allow motion and rest to be measured. Imagine two scientists, Terra and Stella. Each is in their own frame of reference, but Terra on Earth, Stella in a spacecraft traveling past our planet. Terra sees Stella's frame of reference (the spacecraft) moving in relation to her own (the Earth), which is at rest. Stella, meanwhile, sees her frame of reference at rest while it is Terra's frame of reference in motion as the Earth races away. Poplawski pointed out that if the universe is rotating, then its frame of reference is rotating, and that only makes sense if it is rotating in relation to at least one other frame of reference. "If the universe is rotating, it must rotate relative to some frame of reference corresponding to something bigger," he continued. "Therefore, the universe is not the only one; it is a part of a multiverse." For Poplawski, the simplest and most natural explanation of the origin of the rotation of the universe is black hole cosmology. Black hole cosmology suggests that every black hole creates a new baby universe on the other side of its event horizon, the one-way light-trapping surface that defines the outer boundary of a black hole. The theory replaces the central singularity at the heart of a black hole with "spacetime torsion" that gives rise to repulsive gravity that kick-starts the expansion of a new universe. "Because all black holes form from rotating objects, such as rotating stars or in the centers of rotating galaxies, they rotate too," Poplawski said. "The universe born in a rotating black hole inherits the axis of rotation of the black hole as its preferred axis." In other words, our universe may be spinning in a preferred direction because that is the way that the black hole it is sealed within is spinning. "A black hole becomes an Einstein-Rosen bridge or a 'wormhole' from the parent universe to the baby universe," Poplawski explained. "Observers in the new universe would see the other side of the parent black hole as a primordial white hole." In lieu of discovering a primordial white hole in our universe leading to our parent black hole and progenitor universe, the strongest evidence of this black hole cosmology is a preferred direction or "rotational asymmetry" in our universe. That can be seen in rotational asymmetry in the galaxies. "The motion of individual galaxies in that baby universe will be affected by the rotation of that universe," Poplawski said. "The galaxies will tend to align their axes of rotation with the preferred axis of the rotation of the universe, resulting in the rotation asymmetry, which can be observed." That's something astronomers are starting to see. Of course, that means that every black hole in our universe is a doorway to another baby cosmos. These infant universes are protected from investigation by the event horizon of their parent black holes, which prevents any signal from being received from the interior of a black hole. Likewise, a trip through this cosmic doorway would be impossible for a budding "multinaut" due to the immense gravity surrounding a black hole, which would give rise to tidal forces that would "spaghettify" such an intrepid explorer. Even if such a multinaut were to survive the journey, just as nothing can escape a black hole, nothing can enter a white hole, meaning there would be no return or opportunity to file a report! Even grimmer than this, there's no guarantee that the laws of physics are the same in a baby universe as their parent universe, meaning an unpredictable fate and potentially a messy death for a hardy multinaut able to brave a black hole doorway. Anyway, before we rush off to explore other universes, there are mysteries to be investigated right here in our own universe. At the forefront of these is the mysterious force of dark energy. Dark energy is a placeholder name given to whatever force is causing the universe to expand at an accelerating rate. Dark energy currently dominates the universe, accounting for 68% of the total cosmic matter-energy budget. This wasn't always the way, though. During the universe's earliest epoch, it was dominated by the energy of the Big Bang, causing it to inflate. As the universe entered a matter-dominated epoch ruled by gravity, this inflation slowed to a near stop. This should have been it for the cosmos, but around 9 billion to 10 billion years after the Big Bang, the universe started to expand again, with this expansion accelerating, leading to the dark-energy dominated epoch. To understand why this is such a worrying puzzle, imagine giving a child on a swing a single push, watching their motion come to a halt, and then, for no discernible reason, they start swinging again, and this motion gets faster and faster. As if dark energy weren't strange enough already, recent results from the Dark Energy Spectroscopic Instrument (DESI) have indicated that this mysterious force is weakening. This is something that seemingly defies the standard model of cosmology or the Lambda Cold Dark Matter (LCDM) model, which relies on dark energy (represented by the cosmological constant or Lambda) being constant. However, Poplawski theorizes that a spinning universe can both account for dark energy and explain why it is weakening. "Dark energy would emerge from the centrifugal force in the rotating universe on large scales," the theoretical physicist explained. "If the universe were flat, the centrifugal force would act only in directions perpendicular to the preferred axis." However, in Poplawski's black hole theory of cosmology, because the universe created by a black hole is closed, moving away in any direction would eventually lead to coming back from the opposite direction. That would mean the centrifugal force arising from a spinning universe becomes a force acting in all directions away from the universe's parent primordial white hole. "The magnitude of this force is proportional to the square of the angular velocity of the universe and the distance from the white hole," Poplawski said. "This relation takes the form of the force acting on a galaxy due to dark energy, which is proportional to the cosmological constant and the distance from the white hole. Therefore, the cosmological constant is proportional to the square of the angular velocity of the universe." But, how could this explain the DESI observations that seem to indicate that dark energy is getting weaker? "Because the angular momentum of the universe is conserved, it decreases as the universe expands," Poplawski said. "Consequently, the cosmological constant, which is the simplest explanation of dark energy, should also decrease with time. This result is consistent with recent observations by DESI." To provide some further evidence of Poplawski's concept, more data on the bulk flow of galaxy clusters and on the asymmetry of galaxy rotation axes are needed. This would help further confirm that our universe is rotating. Additionally, more data regarding how dark energy depends on cosmic distances and the progression of time in our 13.7 billion-year-old cosmos could help validate whether the weakening of dark energy is related to the decreasing angular velocity of the universe. "The next step to advance these ideas is to determine the equation describing how the cosmological constant, generated by the angular velocity of the universe, decreases with time, and to compare this theoretical prediction with the observed decrease of dark energy," Poplawski concluded. "This research might involve searching for the metric describing an expanding and rotating universe." A pre-peer-reviewed version of Poplawski's research appears on the paper repository site arXiv.

To employers, AI skills aren’t just for tech majors anymore

By the time Christian Vivas enrolled in a new artificial intelligence program at Miami Dade College, he had already experimented with using ChatGPT to help him write emails to clients of the creative media studio he owns. Vivas said most of his classmates were like him — adults well into their careers looking to learn how to use AI, or use it better. Thanks to his classes, Vivas, who is 37 and has a bachelor’s degree in electrical engineering, has gone way beyond using ChatGPT. He now employs AI in nearly every aspect of his work: generating images, videos, marketing plans, social media captions. “It’s integrated very deeply into our business now,” Vivas said. Generative AI technology is rapidly changing the labor market. Employers are increasingly posting job listings that include AI skills for positions even outside of the technology sector, such as in health care, hospitality and media. To keep up, students are increasingly looking for ways to boost their AI skills and make themselves more marketable at a time when there’s growing fear that AI will replace humans in the workforce. And their concerns are justified: There’s evidence to suggest artificial intelligence may have already replaced some jobs. Entry-level positions are particularly at risk of being replaced by AI, a report from Oxford Economics shows, and the unemployment rate for recent college graduates jumped to nearly 6 percent in March, according to the Federal Reserve Bank of New York. A global survey of more than 1,000 large businesses showed 41 percent expect to reduce their workforces within five years because of AI. But most companies — 77 percent — also plan to train their employees to “better work alongside AI,” according to the World Economic Forum’s January Future of Jobs report. Last year, the number of online job postings that included generative AI as a desired skill grew 323 percent, from fewer than 16,000 to more than 66,000, according to a report from the labor analytics company Lightcast. Related: Interested in more news about colleges and universities? Subscribe to our free biweekly higher education newsletter. Colleges are also motivated by these trends: They’re adding AI to their course catalogs, and individual professors are altering lessons to include AI skill building. Miami Dade College, for example, debuted its artificial intelligence certificate program in 2023, just over a month after ChatGPT was unveiled. The program offers classes in machine learning, ethics and natural language programming, among other courses. Since rolling out the certificate program, the school has added associate and bachelor’s degree programs in applied AI. “We started developing this idea around the application of AI — how you can apply AI, how can you learn AI at a community college — where it is open to everyone, not just to a few who can get a master’s or Ph.D.,” said Antonio Delgado, vice president of innovation and technology partnerships at Miami Dade College. In 2022, the college also created Miami Tech Works, an organization that helps tech companies find skilled workers. Recently, more businesses outside of tech have reached out to hire people who know how to use AI. “We didn’t know there would be so many employers talking about AI and talking about implementing AI,” said Terri-Ann Brown, director of Miami Tech Works. Brown said the owner of a high-end hotel in South Florida told her that a year ago, the hotel’s executives were worried about AI taking their jobs. Now, each department at the hotel has been charged with researching AI tools and reporting ways they can use them. For example, one department created an online chatbot to recommend restaurants to hotel guests. Miami Dade College’s programs have attracted students like Vicky Cheung, who decided to enroll in the college’s artificial intelligence awareness certificate program in 2024, after she was let go from the Miami hospital where she had worked for more than two decades. Cheung, who already had a bachelor’s in business and a master’s in health management, was looking into courses that would give her skills she could add to her resume. She believes her AI courses, coupled with her years of work experience, helped her land her new job analyzing how to improve processes and workflow at a different hospital. Enrolling in the program showed employers “that I’m trying to find a way to improve my skill sets,” she said. Related: University students offload critical thinking, other hard work to AI Schools across the country have announced programs similar to the one at Miami Dade College: courses in artificial intelligence in business settings and minors in AI marketed to students who are not computer science majors. But higher education institutions are not inherently nimble — and the technology is evolving quickly. Because generative AI is changing so rapidly, there’s no one curriculum or credential schools are using, or can look to, as a guidepost. What these lessons look like and the rules about how students should use AI vary by institution, or even classroom to classroom. “Institutions are really built to move slowly — there are committees, policies, there’s accreditation. It’s almost in their DNA to not move fast,” said Josh Jones, CEO of QuantHub, a company that works with schools including the University of Alabama and Emory University to add artificial intelligence lessons. “The problem we have is that AI is changing industries so fast that the textbooks, the curriculum — by the time you get it approved, it’s relevant, but it’s outdated.” There are ethical implications for using generative AI as well — from students using the technology to cheat on assignments to the demand that data centers are putting on the nation’s water supply. Some studies indicate college students who use AI on assignments are less engaged with their lessons and use it to offload critical thinking. Higher education institutions across the country have issued nearly identical statements acknowledging the risks, but also the need, for students to learn how to use artificial intelligence to prepare for the working world. The challenge for colleges will be getting that balance right, producing graduates who know how to use artificial intelligence but are not wholly reliant on it. James Taylor, a philosophy professor at The College of New Jersey, changed his classroom setup about a year and a half ago to prevent students from using AI on his assignments. Now, when the class has to write an essay, they do it by hand while in the room. When students take a test, they do it with paper and pencil via blue books. Related: What aspects of teaching should remain human? Taylor doesn’t have a problem with students using AI in other classrooms and believes students should learn how to use AI tools, to some degree. He doesn’t want students using it to get around having to think critically, however, a skill they will need even if they use AI in their future jobs. “What we’re trying to do is teach students how to think, how to identify arguments, analyze arguments, put together their own arguments,” Taylor said. “When they just use AI to do this, they don’t gain any of the critical thinking skills that they need.” For Derrick Anderson, who teaches public affairs at Arizona State University and is senior vice president at the American Council on Education, it’s simple: If AI is a tool students will use at jobs, they should learn how to use it in his classroom. “Because I’m preparing them for the job market, they need to know how to use generative AI ethically, but efficiently and effectively,” Anderson said. Now, instead of having students write an essay at the end of one of his public affairs courses, Anderson has them produce a video with the help of ChatGPT. One student in Anderson’s class created a video about new technology that mimics the human brain. In the video, the student narrates as an AI-generated image of a model brain spins on the screen. When he starts talking about the electrical output of supercomputers, the video cuts to wind turbines spinning atop AI-generated grassy hills. Previously, one of Anderson’s class assignments required students to write a memo; now, they have to write four different kinds of memos using ChatGPT and describe scenarios where they would be appropriate. “It’s a fundamentally different exercise that involves a much larger volume of content because content is so much easier to create,” Anderson said. The students in his classes have used their AI videos and projects in their portfolios when looking for jobs to show they have experience with these programs, even if they lack a specific degree or credential. Related: AI might disrupt math and computer science classes — in a good way Employers are looking for those kinds of demonstrable examples of AI skills from graduates, said Ken Finneran, vice president of human resources at the digital health care company eMed, since there is no industry-recognized credential for the AI skills needed in a certain profession. Instead, hundreds of varying credentials are offered by companies, including Google and IBM. Every department at eMed, from marketing to human resources to finance, uses generative artificial intelligence tools in some way, said Finneran, and the company expects all prospective employees to have some foundational knowledge of AI. The company’s departments are about 20 to 30 percent more productive after using AI tools to complete tasks, Finneran said. And he believes doctors who use AI are better at diagnosing patients than either the doctor or an artificial intelligence program alone. “Those who are hesitant or even blockers around AI will not be the leaders, even if they have a tradition of being an industry leader, within the next two years,” Finneran said. “They will be overtaken by those who are effectively leveraging AI.” Vivas, the creative media studio owner, said some of the freelancers he works with have approached him with concerns about generative artificial intelligence: photography models worried about being replaced by AI generated images and contract marketers concerned it will make them irrelevant if people start using ChatGPT to spit out their own marketing plans. Vivas said he doesn’t plan to use AI to fully replace humans, and he doesn’t believe other employers will either. But he does think workers who ignore the technology do so at their own peril. “It’s not that AI is going to replace them,” he said, “but the person that is using AI is going to replace them.” Contact reporter Ariel Gilreath on Signal at arielgilreath.46 or at gilreath@hechingerreport.org.

Re-building trust and a new financing framework: H20 Summit to set the stage for G20 health priorities

Leading G20 policy-makers, global health experts and representatives from both the private and public sectors are meeting in Geneva from 19–20 June for the annual Health20 Summit (H20) organized by the G20 Health & Development Partnership and co-hosted by the World Health Organization (WHO). The Summit comes at a critical moment for global health amid geopolitical shifts, economic uncertainty, and shock funding cuts to development aid. It will focus on the future of global health and finance, and explore how to build resilience, trust, and sustainability into health systems. This year marks the conclusion of the first cycle of G20 meetings, which began in 1999 as a forum for Finance Ministers and Central Bank Governors of industrialized and developing countries to discuss global economic and financial stability. The H20 Summit, which has been held annually since the first G20 Health Ministers Meeting in Germany in 2017, will explore strategies to secure the role of health and development in the next cycle starting in 2026, under the leadership of the United States of America. Outcomes from the two-day deliberations will inform both the upcoming UN General Assembly’s fourth high-level meeting on noncommunicable diseases (NCDs) in September and the G20 health ministers and leaders’ summit in South Africa this November. “WHO thanks the H20 for its advocacy at this critical time in global health. Severe disruptions to funding and changing disease burdens require new partnerships and approaches, including an increased focus on promoting health and preventing disease," said Dr Tedros Adhanom Ghebreyesus, WHO Director-General. "WHO is working with all health and development partners, and supporting the G20, to help countries pivot from aid dependency to greater self-reliance in mobilizing domestic resources to deliver the health services their people need.” Dr Ghebreyesus delivered the keynote address. Other high-level speakers included: H.E. Dr Jaleela bint Alsayed Jawad Hasan, Minister of Health, Kingdom of Bahrain; H.E. Dr Jean Kaseya, Director General, Africa CDC; H.E. Dr Hanan Al Kuwari, Advisor to the Prime Minister for Public Health Affairs; Former Minister of Health, Qatar H.E. Prof Orazio Schillaci, Minister of Health, Italy; Dr Pakishe Aaron (PA) Motsoaledi, Minister of Health, South Africa; and Dr Sania Nishtar, CEO, GAVI. The first NCDs and Mental Health Global Legislators Report, which offers a toolkit for parliamentarians to advance preventative global health goals; and a second, The health taxonomy report that provides a first framework for a health investment tool aimed at fostering a shared understanding and common language between governments, companies, and investors, to help drive future health financing. This report is pertinent in light of the landmark health financing resolution adopted at last month’s World Health Assembly. Under the theme ‘Reimagining partnerships & building back public trust in global health’ participants at the Summit will discuss the status of global health financing and why public-private partnerships are essential for future progress. The H20 Summit is unique in offering an inclusive and collaborative platform where the traditional global health community can intersect with decision-makers from politics and finance, with the purpose of elevating public health within the G20’s broader development agenda. NCDs such as cancers, diabetes, and chronic respiratory diseases account for more than 43 million deaths each year and are on the rise. Mental health conditions including anxiety, depression, psychosis and self-harm, affect close to 1 billion people worldwide and represent a significant long-term risk to economic growth and security. The NCD and health taxonomy reports offer relevant and actionable recommendations for legislators and governments to close the NCD financing gap. H.E. Dr Jaleela bint Alsayed Jawad Hasan, Minister of Health, Kingdom of Bahrain, said: “I welcome the NCDs and Mental Health Global Legislators Report launched at the H20 Summit. It is a timely contribution that demonstrates the role of parliamentarians in translating health commitments into lasting impact. As global health systems adapt to complex and evolving challenges, the Kingdom of Bahrain is advancing a model grounded in inclusive governance, robust legislation, and strategic investment.” On financing specifically, Dr Agnes Soucat, Director of Health and Social Protection, Agence Française de Développement said: “We must differentiate between health funding and health financing. A health taxonomy already exists for operational costs but not for capital costs, which is what investors are most interested in.” Note to editors The G20 Health & Development Partnership is a not-for-profit advocacy organization representing over 27 global health organizations from across the public and private sector and academia aiming to ensure G20 countries coordinate their current and future health innovation strategies to tackle the growing global burden of communicable and noncommunicable diseases and promote the delivery of the United Nations Sustainable Development Goals by 2030 with a focus on SDG3 ‘health and well-being for all’ and SDG17 ‘strengthening partnerships’.

Titan A.E. came out 25 years ago, and history has been kind to the infamous flop that killed Fox Animation Studios

“After Earth Ends, The Adventure Begins!” Sometimes a work of unique art arrives on the scene that seems misplaced in the stream of time, and this is precisely the fate of "Titan A.E.," a lavish animated space movie set in the 31st century and helmed by the distinguished animators Don Bluth and Gary Goldman. Together, this superstar producing and directing team conjured up a flourish of '80s classics including "The Secret of NIMH," "An American Tail," "The Land Before Time," "Anastasia," and "All Dogs Go to Heaven." Today marks the 25th anniversary of "Titan A.E.," a tarnished Hollywood jewel that has risen impressively in estimation over the decades and is fondly remembered by a certain era of Millennial moviegoers. Released on June 16, 2000 by 20th Century Fox's Fox Animation Studios after less than two years in production, it was an ambitious undertaking that featured a hybrid of 2D hand-drawn animation and CGI-animated sequences, providing a summertime outer space saga complete with a rockin’ soundtrack using bands like Powerman 5000, Electracy, and Fun Lovin’ Criminals. Sadly, the prevailing box office at the time was not kind to "Titan A.E." and despite respectable critical reviews and general young audience enthusiasm, the animated sensation was not a commercial success, only raking in $36.7 million off a rumored budget of $80-90 million. It was this disappointing box office performance that ultimately caused the shuttering of Fox Animation. "I'd say it’s not a 'mother friendly' movie. Although we haven't left the mothers and children out," Goldman admitted to Animation World Magazine in 2000. "There is some swearing, some sexual innuendo, it's intense … there's a lot of violence. I don't think anybody under 8 years old should see this film." In the mid-to-late 1990s, Fox Animation was lusting after some of that sweet Disney gold mined from the House of Mouse's recent hits like "The Lion King," "Pocahontas," "Mulan," and "Tarzan," so they decided to partner up with former Disney animators Don Bluth and Gary Goldman for a hard sci-fi project. Criticized for rehashing storylines already tread upon by properties like "Battlestar Galactica" and "Star Trek," "Titan A.E." faced an uphill battle when released, regardless of its lush, striking visuals. "The look is similar to a graphic novel or dark comic book," Goldman said at the time. "The opening is softer, pastel colors, almost pastoral. The computer graphic imagery and animation are some of our best ever. The CGI work is in about 80% of the film....in 3-D backgrounds, spaceships and the villains. The villains have a gelatin or glass-filled look." "Titan A.E." boasted an impressive vocal cast as well, with the talents of Matt Damon, Drew Barrymore, Bill Pullman, Nathan Lane, John Leguizamo, Ron Perlman, and even Tone "Wild Thing" Loc. Its screenplay was penned by "The Tick's" Ben Edlund, "Big Fish's" John August, and a young Joss Whedon, who would later direct 2014's "The Avengers" for Marvel Studios. The complex project began life as a live-action feature titled "Planet Ice" but bounced around in development hell before its hybrid status was decided upon and Goldman and Bluth signed onto the movie. The basic plotline follows the obliteration of Earth in the far future by the Drej, an alien race comprised of pure concentrated energy. This aggressive species catches wind of something called Project Titan, an enormous spaceship with an even bigger, secretive purpose, and decides that Earthlings pose a threat that must be exterminated. Right before the attack, Professor Sam Tucker (Perlman), Project Titan's chief engineer, hands his young son Cale Tucker (Alex D. Linz) a golden ring and forces him onto an evacuation craft with his alien buddy, Tek (Tone Loc). Sam and his colleagues launch the Titan away from Earth and into hyperspace as their homeworld is vaporized. Fifteen years later, humanity is a vagabond race scattered amid the galaxy. Cale (Damon) is now 20 and working a salvage yard job at Space Station Tau 14 with Tek. They learn from hotshot starship pilot and ex-military officer Joseph Korso (Pullman) that Cale’s inherited ring contains a holographic map that points to the hidden location of the Titan. Cale joins the Valkyrie’s motley crew that includes alluring human pilot Akima Kunimoto (Barrymore) and a trio of aliens: first mate Preed (Lane), astro-scientist Gune (Leguizamo), and weapons expert Stith (Garofalo). Off they go to search for the Titan, the massive spaceship with the technological capability of creating a New Earth, before the Drej queen and her minions find it first and silence humanity forever. Debates over its failure range from the derivative PG-rated screenplay and bumpy development process, to its landing squarely in that netherworld of being ignored by older teens and adults and too mature and violent for small children, dropping it in that abyss between the two ticket-buying demographics. It also didn’t help that Fox Animation had issued widespread layoffs in 1999, nearly gutting the entire department, which eventually led to a total studio closure weeks following "Titan A.E.'s" release. Due to Fox Animation's reduced body count while post-production was being finalized, the film’s marketing and distribution efforts suffered. Whatever the truth, it's a visually-arresting film that deserved more love than it got at the time. Those who've not been introduced to its many fun charms are almost always astonished by its energy, vivid set pieces, and compelling narrative that scratches that diehard sci-fi itch. Elio is on the way for animated sci-fi fans, but if you're looking for something a little grittier this summer, now is the perfect time to revisit "Titan A.E." and get lost in its colorful space opera flair and fantastic fusion of old-school craft and modern CG animation. Plus, it's the only space-based cult classic to feature a newborn planet named Bob!

外媒：黄金逼近历史高位，两大因素推高金价

【环球网财经综合报道】6月16日，金价涨幅已被抹去，当前交易价格接近每盎司3430美元，较4月创下的历史高点低约70美元。彭博社报道指出，2025年，黄金价格上涨了30%以上，各国央行寻求减少对美元的依赖、实现资产多元化也是推动金价上涨的另一个重要因素。 彭博社援引Guardian Gold Australia分析师John Feeney观点称：“金价仍非常接近历史高位，鉴于当前的局势，任何进一步的升级都将推动金价继续走高。”该分析师认为，“黄金最近作为避险资产表现十分出色，似乎很多投资者都在将资金从美国债券中撤出，并长期转向黄金。” 在弱于预期的美国通胀和就业数据引发市场对美联储将在今年晚些时候降息的押注后，金价在上周五（6月13日）上涨了1.4%，而此前它已连续两日上涨。由于黄金不产生利息，较低的利率往往对黄金有利。（闻辉）

Schools Can’t Find Teachers. Do States Need More Credential Rules or Fewer?

For Aspire Public Schools in Los Angeles, the turnaround took a couple of years. Coming back from the pandemic, the 11 charter schools serving about 4,400 students saw a steep drop in credentialed teachers sticking with their roles. So relying on a program at Alder Graduate School of Education that pays graduate students to work as teachers-in-training, Aspire built an internal pipeline of new educators. The program has been successful, according to Christopher Carr, executive director for Aspire in Los Angeles. The retention rate for teachers in the network has soared from around 60 percent to 90 percent, Carr reports. The biggest success of the school's internal pipeline has been in special education, which suffered the highest personnel loss after the pandemic. But perhaps the best benefit has been that this allows incoming teachers to absorb the culture of Aspire. Aspire focuses on “antiracism,” according to Carr. He credits this approach with helping the network to increase its number of Black teachers, by allowing schools to consciously recruit them. A couple of years ago, around 7 percent of Aspire’s teachers were Black. Now, that number has doubled, to around 14 percent. But it’s still really hard to attract math and science teachers for middle school and high school: “It’s almost impossible to find a physics teacher right now,” he says. Still, to the extent Aspire schools have been successful recruiting and keeping teachers, the chain is in a rare position. In California, like elsewhere in the country, teacher pipelines are drying up. Nationally, states have relaxed educator credential requirements to help schools navigate workforce issues. But without greater investment into alternative teacher-training pipelines, some experts worry that schools’ struggle to find and keep teachers will only get worse. But at the same time, some states have had to make rules more strict: Texas has reversed course on educator credentials, from 2001 — when the state loosened regulations and functionally allowed teachers-in-training to rely on fully online programs — to this year, when it passed a new law to reduce reliance on underqualified educators. State experiments with strict and lenient credential rules have not yet yielded definitive solutions. Comparative Advantage California has some of the most robust teacher qualification requirements, says Beatrice Viramontes, executive director of Teach for America Bay Area. The state’s education system desperately needs quality teachers in schools, but the traditional credential requirements are expensive and include a lot of steps for prospective teachers, Viramontes says. It creates an additional barrier to boosting staff numbers — along with other hurdles like pay — and schools are having a difficult time attracting teachers, especially among younger generations. Gen Z and millennial teachers tend to leave the field earlier. It means that, as older teachers retire, it’s harder to replace them with quality new hires, Viramontes says. Solving the problem has required schools to take on a DIY spirit. “There’s a lot of energy in getting creative, because the current process is cumbersome,” Viramontes says. Teach for America runs an alternative teacher credentialing program. Since the pandemic, schools have started creating their own in-house alternative training programs, too. Some of these try to even usher students currently working to earn a bachelor’s degree through the credential process. Viramontes praises some approaches as “innovative.” For instance, there’s Rivet, a paraprofessional program that works to bring students pursuing a bachelor’s into classrooms; and TeachStart, a teacher academy that specializes in pathways to credential substitute teachers. But others have warned about teacher quality issues when schools have to rely on substitutes and other uncredentialed instructors. California doesn’t have good metrics for weighing the quality of these alternative programs, Viramontes concedes. Yet, anecdotally, she says there’s a steady flow of demand from schools for these programs, which she argues speak to “a yearn” for more teachers. Precisely how this affects schools depends on where they are. In rural areas of the central coast region of California, online options have made certification more accessible, says Caprice Young, CEO and superintendent of Navigator Schools. A charter network of four schools, Navigator has around 2,200 students in transitional kindergarten through eighth grade, and around 300 staff (about 100 are teachers). Three of the network’s schools are rural, all sitting about 40 or 50 miles outside of San Jose, with a fourth school in Hayward, wedged between San Jose and Oakland. For teachers, the schools largely rely on the Cal State University system's TEACH program, which has a virtual credentialing option. It’s common for Navigator schools to cultivate teachers internally, Young says. With the end of federal pandemic relief funding, Navigator schools have focused on hiring tutors and paraprofessionals who can transition into teaching roles, and they have put energy into teacher coaching programs. But long term, this could be a problem. Tutors and paraprofessionals are now moving into vacant teaching positions, and without additional federal dollars, the schools aren’t filling as many as many of the paraprofessional jobs. Still, the schools find themselves adding grade levels, Young says. With nearby schools dwindling because of enrollment declines, the pool of teachers they can hire has swelled. But as other states have learned, finding more teachers isn’t the end of the woes. Carrots and Sticks In Texas, there’s another problem. Recently, the governor signed H.B. 2, which bans uncertified teachers from instructing in “core” subjects (reading, math, science and social studies) in public schools by the 2029-2030 school year. Texas has a relatively deregulated teacher preparation certification landscape, says Jacob Kirksey, an assistant professor in Texas Tech’s College of Education. A waiver from the District of Innovation policy from before the pandemic has meant that Texas public school districts don’t have to get approval from the state education agency for hiring uncertified teachers if they can demonstrate they have a shortage, Kirksey says. Some of Kirskey’s work has suggested that, as of two years ago, half of new hires lacked credentials, a trend that disproportionately affects rural areas. Teacher shortages have been the worst in math and sciences for middle and high school, he says, a pattern that’s also worse in rural regions. Many states appear to be following Texas’ old lead in allowing more uncertified teachers to head classrooms, Kirskey adds. In 2024, more than 365,000 teachers across 49 states plus D.C. were working without being fully certified for their positions, according to the Learning Policy Institute. And some states like South Carolina and Indiana recently passed legislation loosening credential requirements. While this may boost the number of bodies in classrooms, it also raises questions about the quality of instruction. Kirksey’s work has highlighted the connection between uncredentialed teachers and student achievement declines. With an average uncertified teacher, the students fall behind about three months in math and four months in reading within a single school year, he says. Observers praised the new law in Texas for also making funds available to assist underqualified teachers in the classroom to gain credentials, which they argue will ensure teacher quality while keeping the pipelines of educators flowing, in calls with EdSurge. The law also supports university-based educator preparation programs. Rolling Boulders Uphill Some think that solving the problem of teacher shortages and educators who lack credentials will take more effort. It’s not enough to rely on legislators alone to fix the problem, argues Gemar Mills, executive director of College Achieve, a network of 11 charter schools spread across three cities in New Jersey. In New Jersey, some attempts, predating the pandemic, have kept up the flow of teachers into schools. For example, there’s Trio Academy, a program that supports students without a college degree, helping them earn the degree and then pursue a teaching credential. There’s also a state program — run by the New Jersey Center for Teaching and Learning — meant to boost the supply of science teachers. The program puts certified teachers through a physics graduate program before assisting them in obtaining a credential to teach the subject. Even before the pandemic, Mills embraced this; and he recalls a gym teacher completing the program and becoming a physics instructor. In recent years, the program expanded from physics into other sciences. But the pandemic supercharged the search for alternative sources of teachers: “COVID opened the floodgates for what was allowable,” Mills says. These days, in New Jersey, credentialing sits somewhere between the extremes of California and Texas. The pandemic inspired leniency in the state, prompting policymakers to relax standards for credentialing. Typically, becoming a credentialed teacher there involves meeting a minimum GPA, scoring well on a basic skills test, going through teaching practice and getting a college degree. But under the “limited” certification — a five-year program that started in 2022 — teachers can earn a temporary credential by completing three of those criteria. Ultimately, Mills’ schools saw a surge of college graduates, longtime teachers’ assistants and substitutes all pivoting into full-time teaching. But there are still challenges. For instance, schools are capped so that only 10 percent of teachers can have that lenient credential. College Achieve has maxed out. Plus, finding science, math and special education teachers is still onerous, Mills reports. School leaders are eager to get more teachers. But solving the problem that will require more innovative and effective certification pathways, Mill says.

Exploring new horizons: Growing elderly population in China embraces 'poetry and faraway places' amid silver economy boom

Editor's Note: With China's population of seniors over 60 surpassing 300 million, ensuring a happy and fulfilling life for all elderly individuals has become a pressing concern for both families and the nation. How can the new generation of seniors in China break away from traditional norms and embrace a different lifestyle, supported by AI technology, multiculturalism, and an elder-friendly society? The series "Old Age, New Trends" will explore emerging trends in the silver economy, the creative social norms among senior citizens, and innovative eldercare services. It will examine the opportunities and challenges presented by an aging society, highlighting the diverse lifestyles of seniors and the booming eldercare industry in China. Beneath these new trends lies a reflection of Chinese modernization, which aims to provide more secure systems and dignified lives for its senior population.

(Photo/Courtesy of China Railway Shanghai Group) The morning sun streamed through the curtains. Long Ling opened the window to let in the gentle sea breeze. The 61-year-old then left the hotel with his husband, taking a short stroll to the beach just minutes away. The sun cast a soft orange hue over the water, and Long inhaled deeply, savoring the fresh air. Coming from an inland city in Central China's Hunan Province, Long and her husband, Tian Mu, 63, embarked on a journey across China after their retirement. In March, they spent a few delightful days in South China's Hainan Province where the island charm of sea, sandy beaches, and swaying coconut trees brought them joy and a sense of novelty. Thousands of kilometers away, Shanghai residents Zhao and his wife boarded a train bound for nearby city of Wuxi in Jiangsu Province to enjoy the blooming flowers. Onboard, they found themselves among many other elderly passengers in their sixties and seventies, all aboard a special "silver-haired train" arranged by the railway authorities for senior travelers. As they chatted about light-hearted topics and excitedly took selfies, the atmosphere on the train was filled with laughter and camaraderie. According to data released by the State Council Information Office in January, by the end of 2024, people aged 60 and above in China had surpassed 300 million for the first time, accounting for 22 percent of the country's population. This expanding group of senior citizens is increasingly demanding tailored travel services, presenting new opportunities and higher expectations for China's tourism market. Facing this trend, China unveiled a national-level plan on Sunday to boost consumption, which includes developing silver tourism. Retirees are emerging as a driving force in China's tourism market, said Peng Xizhe, director of the Fudan Institute on Ageing. "Whether from an economic perspective or a focus on humanistic care, the Chinese tourism industry, along with the government and society, is increasingly dedicated to nurturing the 'poetry and faraway places' that some elderly people yearn for," Peng told the Global Times. Chasing dreams Long and Tian had been planning for a long-term travel lifestyle after retiring years ago, and this spring, they finally set off on their journey. Initially, they intended to spend just a few weeks in Hainan. But one day, while strolling through the streets of Hainan's Wenchang City, they were captivated by an advertisement for a wellness sojourn hotel agency specifically for seniors. The ad said that for just 3,700 yuan ($512), one could stay for 130 nights at the agency's nearly 70 hotel branches or its partner hotels across the country. This package includes three meals a day, and can be shared with family members. Without much hesitation, Long contacted the agency's branch hotel in Wenchang and quickly made the payment. "I think this model is fantastic," she told the Global Times. "It's incredibly affordable. Besides, the agency's hotels are spread all over the country, making it perfect for those who like to travel, like me and my husband." Soon, Long and Tian settled into the agency's hotel branch in Wenchang. In the following weeks, they explored some other cities in Hainan, as well as warm southern provinces like Guangdong and Yunnan, staying at local branches of the hotel agency. According to Long, each day of their trip is filled with freedom and a leisurely pace. They wake up before 7 am, enjoy breakfast, and then wander nearby. They return to the hotels for lunch, take afternoon naps, and then engage in activities at the hotels like billiards or archery. Most guests at the wellness sojourn hotels are seniors like them, and they sometimes gather to chat or play cards. Tian expressed his satisfaction with their current travel lifestyle. He recalled how much he loved traveling before retirement, but due to a busy work schedule, his short trips were always rushed. "Now, I have plenty of time every day to enjoy a peaceful life in warm, fresh destinations," he told the Global Times. "Moreover, most of the guests at these hotels are around the same age, so we have companionship and don't feel lonely." In Wuxi, Zhao was enchanted by the breathtaking cherry blossoms that created a dreamy pink world. After a three-day trip, Zhao and his wife took a "silver-haired train" to return to Shanghai with other elderly travelers on Sunday. Zhao spoke highly of his train trip. He had always wanted to visit Wuxi, but found it inconvenient to drive there due to health reasons, and his children were too busy to help. "But going there by train was also good," said Zhao, who added that the senior-friendly train he and his wife took was "thoughtfully arranged in every aspect." The Tian and Zhao couples are among the growing group of "vigorous seniors" in China, said Peng. He said this group, which has witnessed China's reform and opening up and experienced firsthand the country's modernization, now enjoys financial freedom and leisure after retiring. With greater spiritual needs, many of them are no longer content with being busy caring for grandchildren at home; instead, they prefer to travel and explore the beauty of China - an opportunity they may have missed in their youth due to limited money or time. The Tian couple is currently staying at a wellness sojourn hotel branch in the tropical region of southern Yunnan. They plan to return to their hometown in Hunan when the weather warms up, and later, when summer comes, head to cooler places. "This is truly the life I've been longing for," Tian said with a smile on his face. Better serve As more and more seniors hit the road, the Chinese government and the tourism industry are making greater efforts to better serve this group. In December 2024, China released a set of guidelines aimed at deepening the country's elderly care service reforms, advocating for the development of silver tourism and a long-term stay market, and promoting the establishment of wellness sojourn destinations tailored to local conditions. Encouraged by the government, many regions in China have begun projects related to the wellness sojourn of seniors. A service platform named "Dong Nan Xia Bei" being built under the effort of Beijing Association of Senior Care Industries, for instance, has gathered information on approximately 144 retirement travel and long-term stay agencies across the country. Through this platform, the elderly can explore options based on their needs and preferences, such as geographical locations and pricing, allowing them to choose the agencies that best suit them, the People's Daily reported in March. Data from China Railway showed that in 2024, Chinese railway departments operated 1,860 tourist trains, with senior travelers making up nearly 80 percent of the passengers. For elderly travelers looking for short trips, the "silver-haired trains" have become an ideal choice. The "silver-haired train" that the Zhao couple took to Wuxi featured staff to assist with luggage, offered light and easily digestible meals, and stocked common medications on board. "This spring, we will continue launching similar tourist trains to popular flower-viewing destinations near Shanghai," a staff member at China Railway Shanghai Group told the Global Times. Emerging industry China, where people aged 60 and above now exceed 20 percent of its population, expects this figure to reach 30 percent by 2035, with the elderly population to exceed 400 million by then, according to the National Health Commission. "This represents a huge [market] potential in sightseeing, cultural entertainment, and activities, thereby creating a comprehensive tourism industry chain tailored for the elderly," Peng said. Peng said that, at present, this rapidly expanding market still has many areas that require improvement. He calls for collaboration between the government and the industry to enhance regulation and establish standards. The Tian couple shared some inconveniences they encountered while staying at branches of their wellness sojourn hotel agency. "Only some of the branches are equipped with handrails and accessible pathways, which are not very friendly for the guests with mobility issues," Tian said. "The agency did not purchase insurance for us, nor did they have partnerships with medical institutions." Nonetheless, Tian expressed a general satisfaction with his stays at the hotel branches with his wife, as well as this emerging industry as a whole. As the sun began to set, Tian and Long wrapped up their leisurely stroll and returned to their hotel in Yunnan. It was a warm and comfortable day. Long lay on the bed and carefully selected a few photos they had taken earlier that day to share in their family WeChat group. "The scenery here is beautiful, and our hotel is quite nice!" she wrote, accompanied by a smiling emoji at the end.
