Researchers from the startup Overview Energy have successfully demonstrated beaming power from a moving airplane to the ground using near-infrared light. It marks the first step toward space-based solar power satellites that could someday transmit energy from orbit to existing solar farms on Earth. IEEE Spectrum reports: Overview's test transferred only a sprinkling of power, but it did it with the same components and techniques that the company plans to send to space. "Not only is it the first optical power beaming from a moving platform at any substantial range or power," says Overview CEO Marc Berte, "but also it's the first time anyone's really done a power beaming thing where it's all of the functional pieces all working together," he says. "It's the same methodology and function that we will take to space and scale up in the long term."

[...] Many researchers have settled on microwaves as their beam of choice for wireless power. But, in addition to the safety concerns about shooting such intense waves at the Earth, [Paul Jaffe, head of systems engineering] says there's another problem: microwaves are part of what he calls the "beachfront property" of the electromagnetic spectrum -- a range from 2 to 20 gigahertz that is set aside for many other applications, such as 5G cellular networks. "The fact is," Jaffe says, "if you somehow magically had a fully operational solar power satellite that used microwave power transmission in orbit today -- and a multi-kilometer-scale microwave power satellite receiver on the ground magically in place today -- you could not turn it on because the spectrum is not allocated to do this kind of transmission."

Instead, Overview plans to use less-dense, wide-field infrared waves. Existing utility-scale solar farms would be able to receive the beamed energy just like they receive the sun's energy during daylight hours. So "your receivers are already built," Berte says. The next major step is a prototype demonstrator for low Earth orbit, after which he hopes to have GEO satellites beaming megawatts of power by 2030 and gigawatts by later that decade. Plenty of doubts about the feasibility of space-based power abound. It is an exotic technology with much left to prove, including the ability to survive orbital debris and the exorbitant cost of launching the power stations. (Overview's satellite will be built on earth in a folded configuration and it will unfold after it's brought to orbit, according to the company). "Getting down the cost per unit mass for launch is a big deal," Jaffe says. "Then, it just becomes a question of increasing the specific power. A lot of the technologies we're working on at Overview are squarely focused on that."

"The clock is ticking" on the Hubble Space Telescope, writes the space news site Daily Galaxy, citing estimates from the unofficial "Hubble Reentry Tracker" site (which uses orbital data from the site space-track.org, created by tech integrator SAIC): While Hubble was initially launched into low Earth orbit at an altitude of around 360 miles, it has since descended to approximately 326 miles, and it continues to fall... "The solar flux levels are currently longer in duration and more elevated than previously anticipated, resulting in an earlier reentry forecast for the Hubble Space Telescope if no reboost mission is conducted," Hubble Reentry Trackersays the Hubble Reentry Tracker... ["Hubble has been reboosted three times in its history," the site points out, "all by servicing missions using the Space Shuttle."]

NASA partnered with SpaceX in 2022 to explore the feasibility of raising Hubble to its original altitude of 373 miles. Such an adjustment would have bought Hubble a few more years in orbit. However, the future of this plan remains uncertain, as NASA has not made any official announcements to move forward with it... Solar flux levels, which determine atmospheric drag, have increased in recent years, accelerating the telescope's decline. This change in solar behavior means that the possibility of Hubble reentering Earth's atmosphere in the next five to six years is quite high if no corrective action is taken. ["But it is difficult to estimate this value due to the variability of future solar flux," the site cautions. "In the best case, Hubble may not reenter for 15 more years, around 2040. In the worst case, it could reenter in 4 years..."] Once Hubble reaches an altitude of 248 miles, it is expected that it will have less than a year before reentry...

While Hubble's end may be near, there is a promising new project on the horizon: Lazuli, a privately-funded space telescope funded by former Google CEO Eric Schmidt. Lazuli aims to become the first privately-funded space telescope, and it could be the successor Hubble enthusiasts have been hoping for. Schmidt Sciences, the organization behind the telescope, plans to launch Lazuli by 2028, providing a more modern alternative to Hubble with a larger mirror and enhanced capabilities. The telescope's proposed design includes a 94-inch-wide mirror, which is a significant upgrade from Hubble's 94.5-inch mirror, and will feature updated instruments to capture more detailed data than ever before.

It will be the first medical evacuation from the International space station in its 25-year history. The Guardian reports: An astronaut in the orbital laboratory reportedly fell ill with a "serious" but undisclosed issue. Nasa also had to cancel its first spacewalk of the year... The agency did not identify the astronaut or the medical problem, citing patient privacy. "Because the astronaut is absolutely stable, this is not an emergent evacuation," [chief health and medical officer Dr. James] Polk said. "We're not immediately disembarking and getting the astronaut down, but it leaves that lingering risk and lingering question as to what that diagnosis is, and that means there is some lingering risk for that astronaut onboard."
"SpaceX says it's Dragon spacecraft at the International Space Station is ready to return its four Crew-11 astronauts home in an unprecedented medical evacuation on Jan. 14 and 15," reports Space.com: The SpaceX statement came on the heels of NASA's announcement that the Crew-11 astronauts were scheduled to undock from the space station on Jan. 14 and splashdown off the coast of California early on Jan. 15. The Crew-11 Dragon spacecraft will return NASA astronauts Zena Cardman and Mike Fincke to Earth alongside Japanese astronaut Kimiya Yui and Russian cosmonaut Oleg Platanov... NASA officials opted for a "controlled medical evacuation" in order to provide the astronaut better treatment on the ground, NASA chief Jared Isaacman has said...

Dr. James Polk, NASA's chief medical officer, has said the medical issue is not an injury to the astronaut afflicted, but rather something related to the prolonged exposure to weighlessness by astronauts living and working on the International Space Station. "It's mostly having a medical issue in the difficult areas of microgravity and the suite of hardware that we operate in," Polk said.

An anonymous reader quotes a report from CBC.ca: A company largely owned by the French and U.K. governments is pitching Canada on a roughly $250-million plan to provide the military with secure satellite broadband coverage in the Arctic, CBC News has learned. Eutelsat, a rival to tech billionaire Elon Musk's Starlink, already provides some services to the Canadian military, but wants to deepen the partnership as Canada looks to diversify defence contracts away from suppliers in the United States.

A proposal for Canada's Department of National Defence to join a French Ministry of Defence initiative involving Eutelsat was apparently raised by French President Emmanuel Macron with Prime Minister Mark Carney on the sidelines of last year's G7 summit in Alberta. The prime minister's first question, according to Eutelsat and French defence officials, was how the proposal would affect the Telesat Corporation, a former Canadian Crown corporation that was privatized in the 1990s.

Telesat is in the process of developing its Lightspeed system, a Low Earth Orbit (LEO) constellation of satellites for high-speed broadband. And in mid-December, the Liberal government announced it had established a strategic partnership with Telesat and MDA Space to develop the Canadian Armed Forces' military satellite communications (MILSATCOM) capabilities. A Eutelsat official said the company already has its own satellite network in place and running, along with Canadian partners, and has been providing support to the Canadian military deployed in Latvia. "What we can provide for Canada is what we call a sovereign capacity capability where Canada would actually own all of our capacity in the Far North or wherever they require it," said David van Dyke, the general manager for Canada at Eutelsat.

"We also give them the ability to not be under the control of a singular individual who could decide to disconnect the service for political or other reasons."

Scientists are putting Einstein's claim that the speed of light is constant to the test. While researchers found no evidence that light's speed changes with energy, this null result dramatically tightens the constraints on quantum-gravity theories that predict even the tiniest violations. ScienceDaily reports: Special relativity rests on the principle that the laws of physics remain the same for all observers, regardless of how they are moving relative to one another. This idea is known as Lorentz invariance. Over time, Lorentz invariance became a foundational assumption in modern physics, especially within quantum theory. [...] One prediction shared by several Lorentz-invariance-violating quantum gravity models is that the speed of light may depend slightly on a photon's energy. Any such effect would have to be tiny to match existing experimental limits. However, it could become detectable at the highest photon energies, specifically in very-high-energy gamma rays.

A research team led by former UAB student Merce Guerrero and current IEEC PhD student at the UAB Anna Campoy-Ordaz set out to test this idea using astrophysical observations. The team also included Robertus Potting from the University of Algarve and Markus Gaug, a lecturer in the Department of Physics at the UAB who is also affiliated with the IEEC. Their approach relies on the vast distances light travels across the universe. If photons of different energies are emitted at the same time from a distant source, even minuscule differences in their speeds could build up into measurable delays by the time they reach Earth.

Using a new statistical technique, the researchers combined existing measurements of very-high-energy gamma rays to examine several Lorentz-invariance-violating parameters favored by theorists within the Standard Model Extension (SME). The goal was ambitious. They hoped to find evidence that Einstein's assumptions might break down under extreme conditions. Once again, Einstein's predictions held firm. The study did not detect any violation of Lorentz invariance. Even so, the results are significant. The new analysis improves previous limits by an order of magnitude, sharply narrowing where new physics could be hiding.

Astronomers using the Vera C. Rubin Observatory have discovered a record-setting asteroid, known as 2025 MN45, nearly half a mile wide and spinning once every 1.88 minutes -- the fastest known rotation for an object of its size. "This is now the fastest-spinning asteroid that we know of, larger than 500 meters," said Sarah Greenstreet, University of Washington astronomer and lead author of the study. The findings have been published in the The Astrophysical Journal Letters. GeekWire reports: 2025 MN45 is one of more than 2,100 solar system objects that were detected during the observatory's commissioning phase. Over time, the LSST Camera tracked variations in the light reflected by those objects. Greenstreet and her colleagues analyzed those variations to determine the size, distance, composition and rate of rotation for 76 asteroids, all but one of which are in the main asteroid belt between the orbits of Mars and Jupiter. (The other asteroid is a near-Earth object.)

The team found 16 "super-fast rotators" spinning at rates ranging between 13 minutes and 2.2 hours per revolution -- plus three "ultra-fast rotators," including 2025 MN45, that make a full revolution in less than five minutes. Greenstreet said 2025 MN45 appears to consist of solid rock, as opposed to the "rubble pile" material that most asteroids are thought to be made of. "We also believe that it's likely a collisionary fragment of a much larger parent body that, early in the solar system's history, was heated enough that the material internal to it melted and differentiated," Greenstreet said. She and her colleagues suggest that the primordial collision blasted 2025 MN45 from the dense core of the parent body and sent it whirling into space.

Jupiter's moon Europa is on the short list of places in our solar system seen as promising in the search for life beyond Earth, with a large subsurface ocean thought to be hidden under an outer shell of ice. But new research is raising questions about whether Europa in fact has what it takes for habitability. Reuters: The study assessed the potential on Europa's ocean bottom for tectonic and volcanic activity, which on Earth facilitate interactions between rock and seawater that generate essential nutrients and chemical energy for life. After modeling Europa's conditions, the researchers concluded that its rocky seafloor is likely mechanically too strong to allow such activity.

The researchers considered factors including Europa's size, the makeup of its rocky core and the gravitational forces exerted by Jupiter, the solar system's largest planet. Their evaluation that there probably is little to no active faulting at Europa's seafloor suggests this moon is barren of life.

"On Earth, tectonic activity such as fracturing and faulting exposes fresh rock to the environment where chemical reactions, principally involving water, generate chemicals such as methane that microbial life can use," said planetary scientist Paul Byrne of Washington University in St. Louis, lead author of the study published on Tuesday in the journal Nature Communications. "Without such activity, those reactions are harder to establish and sustain, making Europa's seafloor a challenging environment for life," Byrne added.

North Dakota passed a law last May to promote development of rare earth minerals in the state. But the law's language apparently also includes two fake mineral names, according to the Bismarck Tribune, "that appear to be inspired by coal company lawyers who worked on the bill." The inclusion of fictional substances is being called an embarrassment by one state official, a possible practical joke by coal industry leaders and mystifying by the lawmakers who worked on the bill, the North Dakota Monitor reported.

The fake minerals are friezium and stralium, apparent references to Christopher Friez and David Straley, attorneys for North American Coal who were closely involved in drafting the bill and its amendments. Straley said they were not responsible for adding the fake names. "I assume it was put in to embarrass us, or to make light of it, or have a practical joke," Straley said, adding it could have been a clerical error.

Agriculture Commissioner Doug Goehring questioned the two substances listed in state law during a recent meeting of the North Dakota Industrial Commission, which is poised to adopt rules based on the legislation... Friezium and stralium first appeared in the bill on the last afternoon of the legislative session as lawmakers hurried to pass several final bills... The amended bill is labeled as prepared by Legislative Council for Rep. Dick Anderson, R-Willow City, the prime sponsor and chair of the conference committee. Anderson said the amendments were prepared by a group of attorneys and legislators, including representatives from the coal industry...

Jonathan Fortner, president of the Lignite Energy Council that represents the coal industry, said it's unfortunate this happened in such an important bill. "From the president on down, everyone's interested in developing domestic critical minerals for national security reasons," Fortner said. "While this may have been a legislative joke between some people that somehow got through, the bigger picture is one that is important and is a very serious matter."

"The ancient evolution of fish mouths could help solve a modern source of plastic pollution," writes ScienceAlert.

"Inspired by these natural filtration systems, scientists in Germany have invented a way to remove 99 percent of plastic particles from water. It's based on how some fish filter-feed to eat microscopic prey." The research team has already filed a patent in Germany, and in the future, they hope their creation will help curb a ubiquitous form of plastic pollution that many are unaware of. Every time a load of laundry is done, millions of microplastics are washed from the fibers of our clothes into local waterways. By some estimates, up to 90 percent of plastic in 'sewage sludge' comes from washing machines. This material is then often used in agriculture as soil or fertilizer, possibly exposing those who eat the resulting crops to these pollutants...

Unlike other plastic filtration systems on the market, this one reduces clogging by 85 percent.

The New York Times checks in on U.S. university researchers and start-ups trying to create domestic rare-earth processing facility: There is too little money to be made in rare earths for the elements to be of much interest to mining giants, so the challenge of reestablishing a domestic industry has fallen to small companies like Phoenix Tailings, a Boston-area startup that runs the metal-making plant in Exeter, New Hampshire. A handful of other companies in the United States are processing rare earths in small quantities, including MP Materials, which owns a mine in Mountain Pass, California, and recently began producing rare-earth metal in Fort Worth, Texas. Similar efforts are underway in Europe and Asia. "It's small volumes of low-value materials that are very expensive to process," said Elsa Olivetti, a materials science and engineering professor at the Massachusetts Institute of Technology. "Meaning it's hard to make money."

Phoenix Tailings' New Hampshire operation is about 2 months old, housed in a converted medical device plant. The company buys metric-ton bags of powder — a mixture of neodymium and praseodymium bound with oxygen — from mining and refining companies in the United States, South America and Australia. It funnels that flour-like material into a drying oven and eventually into furnaces that heat it to the temperature of volcanic lava. This circuit takes up less than 15,000 square feet and is designed to generate no emissions other than those associated with the electricity Phoenix Tailings uses. The closed-loop design distinguishes this process from the more energy-intensive techniques used in China, where workers scoop up molten metal with ladles. That approach releases perfluorocarbons, potent greenhouse gases that do not break down easily.
In late 2024 the company was three weeks from bankruptcy — but it's recently been valued at $189 million.

A UK-based company has successfully powered up a microwave-sized space factory in orbit, proving it can run a 1,000C furnace to manufacture ultra-pure semiconductor materials in microgravity. "The work that we're doing now is allowing us to create semiconductors up to 4,000 times purer in space than we can currently make here today," says Josh Western, CEO of Space Forge. "This sort of semiconductor would go on to be in the 5G tower in which you get your mobile phone signal, it's going to be in the car charger you plug an EV into, it's going to be in the latest planes." The BBC reports: Conditions in space are ideal for making semiconductors, which have the atoms they're made of arranged in a highly ordered 3D structure. When they are being manufactured in a weightless environment, those atoms line up absolutely perfectly. The vacuum of space also means that contaminants can't sneak in. The purer and more ordered a semiconductor is, the better it works.

[...] The company's mini-factory launched on a SpaceX rocket in the summer. Since then the team has been testing its systems from their mission control in Cardiff. Veronica Viera, the company's payload operations lead, shows us an image that the satellite beamed back from space. It's taken from the inside of the furnace, and shows plasma - gas heated to about 1,000C -- glowing brightly. [...]

The team is now planning to build a bigger space factory -- one that could make semiconductor material for 10,000 chips. They also need to test the technology to bring the material back to Earth. On a future mission, a heat shield named Pridwen after the legendary shield of King Arthur will be deployed to protect the spacecraft from the intense temperatures it will experience as it re-enters the Earth's atmosphere.

NASA is closing its largest research library at the Goddard Space Flight Center amid budget cuts and campus consolidation, putting tens of thousands of largely non-digitized historical and scientific documents at risk of being warehoused or discarded. The New York Times reports: Jacob Richmond, a NASA spokesman, said the agency would review the library holdings over the next 60 days and some material would be stored in a government warehouse while the rest would be tossed away. "This process is an established method that is used by federal agencies to properly dispose of federally owned property," Mr. Richmond said.

The shutdown of the library at NASA's Goddard Space Flight Center in Greenbelt, Md., is part of a larger reorganization under the Trump administration that includes the closure of 13 buildings and more than 100 science and engineering laboratories on the 1,270-acre campus by March 2026. "This is a consolidation not a closure," said NASA spokeswoman Bethany Stevens. The changes were part of a long-planned reorganization that began before the Trump administration took office, she said. She said that shutting down the facilities would save $10 million a year and avoid another $63.8 million in deferred maintenance.

Goddard is the nation's premiere spaceflight complex. Its website calls it "the largest organization of scientists, engineers, and technologists who build spacecraft, instruments, and new technology to study Earth, the Sun, our solar system, and the universe." [...] The library closure on Friday follows the shutdown of seven other NASA libraries around the country since 2022, and included three libraries this year. As of next week, only three -- at the Glenn Research Center in Cleveland, the Ames Research Center in Mountain View, Calif., and the Jet Propulsion Laboratory in Pasadena, Calif. -- will remain open.

Warren Buffett is retiring as CEO of Berkshire Hathaway at age 95, ending a 55-year run that reshaped how generations of Americans think about investing. "The 95-year-old, often referred to as the 'Oracle of Omaha' and the 'billionaire next door,' will relinquish the title after a career that saw him turn a failing textile firm into one of the most successful asset managers in the world," reports NBC News. From the report: Greg Abel, the 63-year-old lesser-known CEO of Berkshire's energy business, will take the helm of the conglomerate on Thursday. Buffett will remain its chairman.

Under Buffett's leadership, Nebraska-based Berkshire has thrived at the intersection of Wall Street and Main Street, with investments in industries ranging from railroads and insurance to candy and ice cream.

Along the way, while living in the same house he bought for just over $30,000 in the late 1950s, he redefined investing for the American public with his folksy and practical advice, became one of the wealthiest people on Earth and dedicated much of that fortune to philanthropy. Berkshire's most significant tech bet was initiated in 2016 when it invested $1 billion. Apple has since become Berkshire Hathaway's largest single holding, representing over 20% of the portfolio and valued at more than $65 billion.

While Buffett largely avoided pure tech for decades, Buffett long considered technology a blind spot, famously saying "I wish I had" bought Apple earlier.

Throughout the years, Buffett expressed his disinterest in cryptocurrency and said he would "never own bitcoin," referring to it as "probably rat poison squared" and a "gambling token."

An anonymous reader shares a report: Getting to space is hard. In many ways, getting back is even harder. NASA soon aims to pull off the kind of re-entry it last conducted more than 50 years ago: safely returning astronauts to Earth after they fly to the moon and back. The mission is a big moment for NASA, which will put a crew on its Orion ship for the first time. The flight will test the spacecraft's heat shield, designed to protect the astronauts on board.

Re-entries of vehicles from orbit remain one of the high-stakes parts of any human spaceflight, given the stress they put on spacecraft. In 2003, NASA's Columbia Space Shuttle broke apart as it came back from low-Earth orbit due to a breach on the vehicle that occurred during launch. All seven astronauts on board were killed. Orion will be coming back to Earth from much further away than low-Earth orbit, where all recent human spaceflights have been conducted. That means its velocity and the energy it needs to disperse will be greater, putting even more stress on the heat shield.

During a test flight in 2022 that didn't include astronauts, Orion's heat shield didn't perform as expected. That sparked worries about crew safety on future missions, prompting NASA to investigate and address what happened. NASA will launch Orion with the astronauts on board as soon as February. [...] When the vehicle initially re-enters the Earth's atmosphere, it will be traveling around 25,000 miles an hour and face temperatures of 5,000 degrees as it slows down. The Orion craft, developed by Lockheed Martin for NASA, has a shield that is almost 17 feet in diameter. Installed on the vehicle's underside, the shield is covered in what is called an "ablative" material, which is designed to shift heat away from the craft during re-entry by burning off in a controlled manner.

An anonymous reader quotes a report from DW: India has surpassed Japan to become the world's fourth-largest economy, according to calculations in the Indian government's end-of-year economic review. On current trends, India is expected to overtake Germany to become the world's third-largest economy within the next three years, the review said.

The review said India's gross domestic product has already reached about $4.18 trillion, and is projected to reach $7.3 trillion by 2030. On current trends, it said, India would trail only the United States and China in economic heft. India's real GDP grew 8.2% in the second quarter of the 2025-26 financial year, up from 7.8% in the previous quarter and marking a six-quarter high.

Export performance has also strengthened, the review noted. Merchandise exports rose to $38.13 billion in November, up from $36.43 billion in January, supported by engineering goods, electronics, pharmaceuticals, and petroleum products. Official confirmation however depends on data due in 2026 when final annual GDP figures are released. The International Monetary Fund suggests India will surpass Japan next year. The Reserve Bank of India has revised its growth forecast for the 2025-26 financial year upward to 7.3%.

An anonymous reader shares a report: The French government on Dec 30 postponed a ban on plastic throwaway cups by four years to 2030 because of difficulties finding alternatives. The ban was meant to start on Jan 1. But the Ministry for Ecological Transition said the "technical feasibility of eliminating plastic from cups" following a review in 2025 justified pushing back the deadline.

It said in an official decree that a new review would be carried out in 2028 of "progress made in replacing single-use plastic cups." It added that the ban would now start Jan 1, 2030, when companies would have 12 months to get rid of their stock. France has gradually rolled out bans on single-use plastic products over the past decade as environmental campaigners have stepped up warnings about the impact on rivers and oceans.

A scheme to encourage climbers to bring their waste down from Mount Everest is being scrapped -- with Nepalese authorities telling the BBC it has been a failure. From the report: Climbers had been required to pay a deposit of $4,000, which they would only get back if they brought at least 8kg (18lbs) of waste back down with them. It was hoped it would begin to tackle the rubbish problem on the world's highest peak, which is estimated to be covered in some 50 tonnes of waste. But after 11 years -- and with the rubbish still piling up -- the scheme is being shelved because it "failed to show a tangible result."

Stingless bees from the Amazon have become the first insects to be granted legal rights anywhere in the world, in a breakthrough supporters hope will be a catalyst for similar moves to protect bees elsewhere. From a report: It means that across a broad swathe of the Peruvian Amazon, the rainforest's long-overlooked native bees -- which, unlike their cousins the European honeybees, have no sting -- now have the right to exist and to flourish. Cultivated by Indigenous peoples since pre-Columbian times, stingless bees are thought to be key rainforest pollinators, sustaining biodiversity and ecosystem health.

But they are faced with a deadly confluence of climate change, deforestation and pesticides, as well as competition from European bees, and scientists and campaigners have been racing against time to get stingless bees on international conservation red lists. Constanza Prieto, Latin American director at the Earth Law Center, who was part of the campaign, said: "This ordinance marks a turning point in our relationship with nature: it makes stingless bees visible, recognises them as rights-bearing subjects, and affirms their essential role in preserving ecosystems."

Yes, greenhouse gas emissions kept rising in 2025, writes Bloomberg (alternate URL here). And the pledges of various governments to lower greenhouse gases "are nowhere near where they need to be to avoid catastrophic climate change..."

But in 2025, "there were silver linings too." The world is decarbonizing faster than was expected 10 years ago and investment into the clean energy transition, including everything from wind and solar to batteries and grids, is expected to have reached a new record of $2.2 trillion globally in 2025, according to research by the Energy & Climate Intelligence Unit, a London nonprofit. "Is this enough to keep us safe? No it clearly isn't," said Gareth Redmond-King, international lead at the ECIU. "Is it remarkable progress compared to where we were headed? Clearly it is...." Global investment in clean tech far outpaced what went into polluting industries. For every $1 funding fossil fuel projects, $2 went into clean power, according to the ECIU. For China, the EU, the U.S. and India, the four largest polluters, it was $2.60.

Funds flowing into renewable power set another record in the first half of this year and were up 10% compared to the same period in 2024, to $386 billion, according to the latest available research by BloombergNEF. Solar and wind grew fast enough to meet all new electricity demand globally in the first three quarters of 2025, according to UK-based energy think tank Ember. That means renewable capacity is set to hit a new record globally this year, with Ember forecasting an 11% increase from 2024. Over the last three years, renewable capacity grew by nearly 30% on average. That puts the world within reach of the goal set at COP 28 in Dubai in 2023 to triple clean power by 2030. China is leading the charge, with the world's largest polluter expected to have delivered 66% of new solar capacity, and 69% of new wind globally this year, according to Ember. Renewables also advanced in parts of Asia, Europe and South America.

The explosive power demand from artificial intelligence is also turning the tide on green technology investment, which had soured in recent years. For the first three quarters of this year, global clean tech investment, which was dominated by funding in next-generation nuclear reactors, renewables and other solutions that help power data centers, has already surpassed all of 2024. That marks the sector's first annual increase since the 2022 peak. And despite President Trump's rollback of climate policies, the S&P's main gauge tracking clean energy is up about 50% this year, outperforming most other stock indexes and even gold. That same enthusiasm has also helped channel more capital into developing and upgrading the power grid, a backbone of the global energy transition.
The article also notes that prices per kilowatt-hour of battery capacity "fell by 8% to a record $108 this year and they're expected to decline a further 3% next year, according to BloombergNEF."

And this year the International Court of Justice "determined that countries risk being in violation of international law if they don't work toward keeping global warming to the 1.5C threshold agreed on at the Paris climate conference in 2015."

An astrophysicist at the University of Rochester writes that "many" of his colleagues in physics "have come to believe that a mystery is unfolding in every microbe, animal, and human." And it's a mystery that:

- "Challenges basic assumptions physicists have held for centuries"
- "May even help redefine the field for the next generation"
- "Could answer essential questions about AI."

In short, while physicists have favored a "reductionist" philosophy about the fundamental laws controlling the universe (energy, mattery, space, and time), "long-promised 'theories of everything' such as string theory, have not borne significant fruit: There are, however, ways other than reductionism to think about what's fundamental in the universe. Beginning in the 1980s, physicists (along with researchers in other fields) began developing new mathematical tools to study what's called "complexity" — systems in which the whole is far more than the sum of its parts. The end goal of reductionism was to explain everything in the universe as the result of particles and their interactions. Complexity, by contrast, recognizes that once lots of particles come together to produce macroscopic things — such as organisms — knowing everything about particles isn't enough to understand reality...

Physicists have always been good at capturing the essential aspects of a system and casting those essentials in the language of mathematics... Now those skills must be brought to bear on an age-old question that is only just getting its proper due: What is life? Using these skills, physicists — working together with representatives of all the other disciplines that make up complexity science — may crack open the question of how life formed on Earth billions of years ago and how it might have formed on the distant alien worlds we can now explore with cutting-edge telescopes. Just as important, understanding why life, as an organized system, is different at a fundamental level from all the other stuff in the universe may help astronomers design new strategies for finding it in places bearing little resemblance to Earth. Analyzing life — no matter how alien — as a self-organizing information-driven system may provide the key to detecting biosignatures on planets hundreds of light-years away.

Closer to home, studying the nature of life is likely essential to fully understanding intelligence — and building artificial versions. Throughout the current AI boom, researchers and philosophers have debated whether and when large language models might achieve general intelligence or even become conscious — or whether, in fact, some already have. The only way to properly assess such claims is to study, by any means possible, the sole agreed-upon source of general intelligence: life. Bringing the new physics of life to problems of AI may not only help researchers predict what software engineers can build; it may also reveal the limits of trying to capture life's essential character in silicon.
