Thousands of Americans Treated With Psilocybin in 2025 (cnn.com) 12

In a new 4,000-word article, CNN tells the story of a retired appellate paralegal and grandmother in her early 70s who was treated for depression with psilocybin. CNN notes there's now retreats featuring psilocybin in a few countries — and while psilocybin is illegal under United States federal law, "In Oregon, 5,935 clients received psilocybin services through Oregon's state-regulated program in 2025." High doses of psilocybin are effective in treating depression, a growing body of research suggests, with promise for other conditions, like PTSD and addiction, said Dr. Albert Garcia-Romeu, associate director of the Center for Psychedelic and Consciousness Research at Johns Hopkins University... Some researchers suggest it disrupts entrenched traffic patterns in the brain or grows new neuron connections to change thinking. Others say the results from psilocybin could have to do with its anti-inflammatory effect, Garcia-Romeu said...

Colorado became the second state to make psilocybin legal with a 2023 law and issued its first healing center" last year. A law adopted in New Mexico last year established that state's Medical Psilocybin Program, now in development... Psilocybin seems to be "knocking on the door of FDA approval," said Dr. Lynn Marie Morski, president of the Psychedelic Medicine Association, which educates health care providers on the therapeutic use of psychedelics so they can answer patients' questions through the lenses of clinical evidence and harm reduction. Psilocybin therapy first received a "breakthrough therapy" designation for treatment-resistant depression from the US Food and Drug Administration in 2018, and now psilocybin drug products are on track to be submitted to the FDA for possible approval in the not-too-distant future.

While psilocybin is illegal under United States federal law, more states are creating their own paths for legal use under state laws.

NASA's First Nuclear-Powered Interplanetary Spacecraft Will Send Helicopters to Mars in 2028 (space.com) 11

After decades of studying, this week NASA announced "a major step forward in bringing nuclear power and propulsion from the lab to space." NASA will launch the Space Reactor-1 Freedom, the first nuclear powered interplanetary spacecraft, to Mars before the end of 2028, demonstrating advanced nuclear electric propulsion in deep space. Nuclear electric propulsion provides an extraordinary capability for efficient mass transport in deep space and enables high power missions beyond Jupiter where solar arrays are not effective.
Steven Sinacore, NASA's program executive for Fission Surface Power who will also oversee the SR-1 Freedom mission, emphasized to CNN that "On the ground the reactor is off. There's no radiation coming from it. It doesn't actually turn on until you're up in space, and that's where the radiation comes from." NASA says they aim to develop the capabilities required "for sustained exploration beyond the Moon and eventual journeys to Mars and the outer solar system."

And Space Reactor-1 Freedom will carry a fleet of tiny helicopters (much like Ingenuity) to explore Mars, reports Space.com: Whereas Ingenuity was a technology demonstrator, however, the Skyfall fleet will have concrete tasks. Chief among them is scout: If all goes to plan, the little choppers will help NASA assess the potential of their target area (wherever that happens to be) to support human exploration. The Skyfall helicopters will carry cameras and ground-penetrating radar to scout a future landing site, to understand the slopes and hazards for human-scale landers," Steve Sinacore, the program executive for NASA's Space Reactors Office, said during the briefing. "They will also map and characterize the subsurface water ice to find out where the water ice deposits are, along with the size, depth and other important characteristics," he added...

And that might not be the end of the line for SR-1 Freedom; NASA may decide to keep flying the spacecraft out into the solar system after it deploys the Skyfall choppers, according to Sinacore. The mission architecture, like much of NASA's exploration portfolio, is not yet finalized.

Transporting Antimatter On a Truck Is Tricky... (smithsonianmag.com) 24

Long-time Slashdot reader Qbertino writes: ... but the CERN Project "Antimatter in motion" just did it. For the first time in history researchers at CERN have transported 92 antiprotons on a truck in a specially designed magnetic enclosure. The test-drive went so well that the researchers spontaneously decided to go another round... The purpose of the experiment was to test the feasibility of transporting antimatter to other facilities in Europe to conduct further antimatter research. German news Tagesschau has a nice report.
CNN reports that the antiproton enclosure was nearly six feet tall and weighed about 1,760 pounds. And Smithsonian magazine explains that it trapped the antiprotons in a vacuum chamber that had to be cooled to around -450 degrees Fahrenheit: Experts used a crane to carefully move the box of precious cargo from a lab onto a truck, which took about three hours, per the Associated Press' Jamey Keaten. Then, they drove the vehicle for roughly 30 minutes around CERN's campus, and subsequently returned the antiprotons to the lab. They worked with so little antimatter that even if it did touch ordinary matter and annihilate, it would release a small amount of energy detectable only by a special instrument, reports the AP.

UK Startup Ignites Plasma Inside Nuclear Fusion Rocket (euronews.com) 42

UK startup Pulsar Fusion says it has achieved the first plasma ignition inside a nuclear fusion rocket engine prototype -- a huge step for space travel that could cut missions to Mars "from months-long journeys to just a few weeks," reports Euronews. From the report: Pulsar Fusion revealed the milestone during a live stream at Amazon's MARS Conference, hosted by Jeff Bezos in California this week, with CEO Richard Dinan calling it an "exceptional moment" for the company. The team successfully created plasma - an intensely hot, electrically charged state of matter, often described as the fourth state of matter - using electric and magnetic fields inside its experimental and early prototype "Sunbird fusion exhaust system." [...] The company now plans further testing of its Sunbird system to improve performance. Upcoming upgrades include more powerful superconducting magnets designed to better contain and control plasma.

CERN To Host Europe's Flagship Open Access Publishing Platform (home.cern) 30

CERN has confirmed it will host an expanded version of Open Research Europe, the EU-backed fee-free open access publishing platform that works to "keep knowledge in public hands." Research Professional News reports: A little over a year ago, 10 European research organizations announced that they would add their support to Open Research Europe, to broaden eligibility beyond only those researchers funded by the EU research program. Earlier this year, RPN reported that this group had expanded further and that Cern was set to host the broadened version of ORE, currently provided by the publisher F1000.

On March 26, Cern itself finally announced the news, saying it will "provide the technical and operational infrastructure" for the broader version. It said this will build on its "longstanding experience in developing and maintaining open science infrastructures and community-governed services." [...] In its own announcement, the Commission said ORE will have a budget of 17 million euros for 2026-31, with the EU providing 10 million euros.

Since it launched five years ago, ORE has published more than 1,200 articles. Cern said the platform is "expected to support a growing number of research outputs each year." Last month, experts told RPN they thought uptake of the increased eligibility will depend on how the newly participating national organizations engage with their communities. Eleven members of Science Europe, a group of major research funding and performing organizations, are part of the expansion.

Researchers At CERN Transport Antiprotons By Truck In World-First Experiment (physicsworld.com) 69

An anonymous reader quotes a report from Physics World: Researchers at the CERN particle-physics lab have successfully transported antiprotons in a lorry across the lab's main site. The feat, the first of its kind, follows a similar test with protons in 2024. CERN says the achievement is "a huge leap" towards being able to transport antimatter between labs across Europe. [...] To do so, in 2020 the BASE team began developing a device, known as BASE-STEP (for Baryon-Antibaryon Symmetry Experiment-Symmetry Tests in Experiments with Portable Antiprotons), to store and transport antiprotons. It works by trapping particles in a Penning trap composed of gold-plated cylindrical electrode stacks made from oxygen-free copper that is surrounded by a superconducting magnet bore operated at cryogenic temperatures.

The device, which also contains a carbon-steel vacuum chamber to shield the particles from stray magnetic fields, is then mounted on an aluminium frame. This allows it to be transported using standard forklifts and cranes and withstand the bumps and vibrations of transport. In 2024, BASE researchers used the device to transport a cloud of about 105 trapped protons across CERN's Meyrin campus for four hours. After that feat, the researchers began to adjust BASE-STEP to handle antiprotons and yesterday the team successfully transported a trap containing a cloud of 92 antiprotons around the campus for 30 minutes, traveling up to 42 km/h.

With further improvements and tests, the team now hope to transport the antiprotons further afield. The first destination on the team's list is the Heinrich Heine University (HHU) in Dusseldorf, Germany, which would take about eight hours. "This means we'd have to keep the trap's superconducting magnet at a temperature below 8.2 K for that long," says BASE-STEP's leader Christian Smorra. "So, in addition to the liquid helium , we'd need to have a generator to power a cryocooler on the truck. We are currently investigating this possibility." If possible to transport to HHU, physicists would then use the particles to search for charge-parity-time violations in protons and antiprotons with a precision at least 100 times higher than currently possible at CERN.

Chandra Resolves Why Black Holes Hit the Brakes On Growth (phys.org) 27

alternative_right shares a report from Phys.org: Astronomers have an answer for a long-running mystery in astrophysics: why is the growth of supermassive black holes so much lower today than in the past? A study using NASA's Chandra X-ray Observatory and other X-ray telescopes found that supermassive black holes are unable to consume material as rapidly as they did in the distant past. The results appeared in the December 2025 issue of The Astrophysical Journal.

[...] The team ran tests of the three main possible scenarios currently being considered for the slowdown of black hole growth. These options were: could the decline in black hole growth be caused by less efficient rates of consumption, or by smaller typical black hole masses, or by fewer actively growing black holes? Their analysis of the data, extending over billions of years of cosmic history, led them to the conclusion that black holes are indeed consuming material less rapidly the later they are found after the Big Bang. The researchers expect this trend of slower-growing black holes to continue into the future.

NASA Halts Work On Gateway To Develop a Lunar Base (spacenews.com) 73

NASA is reportedly halting work on the lunar Gateway in favor of a more direct push to build a lunar base. The new plan would cost tens of billions over the next decade, though the change could face hurdles because Congress previously funded Gateway specifically. SpaceNews reports: "Starting today, we're building humanity's first deep space outpost," said Carlos Garcia-Galan, program executive for NASA's moon base effort. The lunar base will take place in three phases. Phase 1, running from 2026 to 2028, "is all about getting to the moon reliably," he said. That includes a significant increase in the cadence of lander missions through the Commercial Lunar Payload Services and other programs. It will also focus on developing enabling technologies and getting "ground truth" for potential base locations at the lunar south pole.

Phase 2, from 2029 through 2031, starts building the base, he said. That would include building out communications, navigation, power and other infrastructure, developing larges CLPS cargo landers and supporting two crewed missions a year. Phase 3, beginning 2032, will enable "long distance and long duration human exploration" on the moon, he said, with routine logistics missions to the moon and uncrewed cargo return missions from the moon. Garcia-Galan said NASA foresees spending $10 billion each on Phases 1 and 2. Phase 3, lasting to at least 2036, would cost an additional $10 billion or more.

The base would leverage existing programs, although with some changes. NASA is planning to revamp the Lunar Terrain Vehicle program after concluding the current approach would take too long to get a crew-capable rover to the moon. "We were projecting a delivery on the lunar surface by 2030," he said. The agency is instead issuing a draft request for proposals for simplified rovers that could be quicker and easier to develop but could be upgraded later. The base, though, would include some new capabilities and technologies. One example Garcia-Galan provided was MoonFall, a drone that would be able to hop from one location to another on the lunar surface. The drones will be "built on the legacy" of Ingenuity, the small Mars helicopter. "We're going to take everything that we learned from Ingenuity's systems, the avionics, all of that, to build this."

Meteor Rumbles Over Houston, as Six-Pound Fragment Crashes Into a Texas Home (cbsnews.com) 45

"It is the talk of the town today — the loud boom, the flash of light in the sky experienced by a lot of folks across the Houston area this afternoon," says a local Texas newscaster. "And then there was this — a home in northwest Harris county hit by something that crashed through their roof."

Travelling at very high speed, the six-pound meteorite crashed through their roof and through their attic, crashing again through the ceiling of the floor below. It then bounced off the floor, hit the ceiling again — and then fell onto the bed.

CBS News reports: NASA said in a social media post that the meteor became visible at 49 miles above Stagecoach, northwest of Houston, at 4:40 p.m. local time. The meteor moved southeast at 35,000 miles per hour, breaking apart 29 miles above Bammel, just west of Cypress Station, NASA said. "The fragmentation of the meteor — which weighed about a ton with a diameter of 3 feet — created a pressure wave that caused booms heard by some in the area," NASA said in the post. Across the Houston area, residents described hearing a low, rumbling sound that many compared to thunder, even though the skies were clear, according to CBS affiliate KHOU.

Earlier this week, an asteroid weighing about 7 tons and traveling at 45,000 mph traveled over multiple states. And last June, a bright meteor was seen across the southeastern U.S. and exploded over Georgia, creating similar booms heard by residents in the area.

Juicier Steaks Soon? The UK Approves Testing of Gene-Edited Cow Feed (telegraph.co.uk) 24

"Juicier steaks could soon be served up after barley was given the go-ahead to become Britain's first gene-edited crop," reports the Telegraph: In an effort to fatten up cows and get them to market faster, scientists have altered the DNA of Golden Promise barley to increase its fat content... [Regulators have approved the feeding of that barley to cows for further studies.] [T]he small increase reduces the time it takes for farmers to raise animals for slaughter and increases the amount of milk and meat they produce to make the industry more profitable.

The gene-edited barley is also able to cut the amount of methane a cow produces, [Rothamsted Research professor/biochemist Peter] Eastmond said... Reducing methane from cattle is a major goal of the industry, and Professor Eastmond estimated his barley could cut the methane output from a single cow by up to 15%.

The two genetic tweaks to the barley are believed to alter the gut bacteria in cows' stomachs and reduce the amount of methane-generating microbes, cutting the cows' emissions.... [Eastmond] is also working on applying the same two gene edits to rye grass to create pastures and meadows which are lipid-rich and calorie-dense. This, he said, could lead to entire fields of gene-edited grass which could be grazed by cows, sheep, horses and goats to fatten them up and cut emissions... "It would be better to have this technology in a pasture grass that's grown to supply the livestock and graze it directly."

The barley "has been modified to have a single letter of DNA removed from two different genes to switch them off," the article points out. "No genes have been added to its DNA and it is not considered to be genetically modified."

The article points out that Britain "has launched a push towards more gene-edited crops as a key post-Brexit freedom since splitting from the European Union," noting that U.K. scientists and private companies "have created products such as bread with fewer cancer-causing chemicals, longer-lasting strawberries and bananas, sweeter-tasting lettuce and disease-resistant potatoes, although these are yet to be granted permission to land on supermarket shelves..."

But the EU has so far resisted the sale of any gene-edited crops in the EU.

Can Private Space Companies Replace the ISS Before 2030? (cnn.com) 31

China's orbital outpost Tiangong was completed in 2022 and is hosting up to three astronauts at a time, reports CNN.

But meanwhile U.S. lawmakers are now signaling there's not time to develop and launch a replacement for the International Space Station — considered the signal most expensive object ever built — before its deorbiting in 2030. A recent Senate bill calls for the U.S. to continue funding it as late as 2032, but that bill still awaits approval from the U.S. Senate and the House.

But some private space companies are already building their alternatives: Private companies that are in the early design and mockup phase of developing these space stations are still waiting on NASA for guidance — and money... [NASA's "Requests for Proposals"] were delayed, in part because it took all of 2025 to cinch a confirmation for Trump's on-again-off-again pick for NASA administrator, Jared Isaacman [confirmed in December]... Similarly, 2025 saw a 45-day government shutdown, the longest in history — adding another hiccup in the space agency's plans to begin formally soliciting proposals from the private sector. Companies now expect that NASA will issue its Request for Proposals in late March or early April, one CEO told CNN...

Several commercial outfits have recently announced big funding influxes aimed at speeding up the development and launch of new orbiting outposts. Houston-based Axiom Space announced a $350 million funding round last month. Its California-based competitor Vast then notched a $500 million raise in early March. Vast is determined to launch a bare-bones station to orbit as soon as possible, with or without federal input, according to the company. "Our approach is to actually not wait for (NASA) and get going and build a minimum viable product, single-module space station called Haven-1, which we're launching into orbit next year," Vast CEO Max Haot told CNN in a phone interview earlier this month. Similarly, Axiom Space is working toward a 2028 launch date for a module that it plans to initially attach to the ISS before breaking off to orbit on its own. A spokesperson told CNN that it the company is "committed" to winning the NASA contract money and may continue pursing such goals even without contract awards.

Still, there's lingering doubt that any of the companies pursuing space stations will be able to stay afloat without securing a coveted NASA contract or at least cinching significant business from the public sector.

The article includes "Another complicating fact: Russia, the United States' primary partner on the ISS, has not pledged to keep operating its half of the space station past 2028." NASA will eventually evaluate proposals for an ISS alternative from Vast, Axiom Space, Jeff Bezos' Blue Origin, Max Space and several competitors including Voyager Technologies, CNN notes, ultimately handing out an estimated $1.5 billion in contracts between 2026 and 2031.

And while those companies may wait decades before a return on their investment, the article includes this quotes from the cofounder/general partner of Balerion Space Ventures, which led the fundraising for Vast. " What's obvious to us is you're going to have multiple vehicles with myriad companies go into space. You're going to have vehicles leaving from celestial bodies, like the moon. And we need a habitat."

NASA's Hubble Unexpectedly Catches Comet Breaking Up (phys.org) 16

NASA's Hubble Space Telescope unexpectedly captured a rare, early-stage breakup of comet C/2025 K1 (ATLAS) just days after it first began disintegrating. Phys.org reports: "Sometimes the best science happens by accident," said co-investigator John Noonan, a research professor in the Department of Physics at Auburn University in Alabama. "This comet got observed because our original comet was not viewable due to some new technical constraints after we won our proposal. We had to find a new target -- and right when we observed it, it happened to break apart, which is the slimmest of slim chances."

Noonan didn't know K1 was fragmenting until he viewed the images the day after Hubble took them. "While I was taking an initial look at the data, I saw that there were four comets in those images when we only proposed to look at one," said Noonan. "So we knew this was something really, really special." Hubble caught K1 fragmenting into at least four pieces, each with a distinct coma, the fuzzy envelope of gas and dust that surrounds a comet's icy nucleus. Hubble cleanly resolved the fragments, but to ground-based telescopes, at the time they only appeared as barely distinguishable, bright blobs. [...]

"Never before has Hubble caught a fragmenting comet this close to when it actually fell apart. Most of the time, it's a few weeks to a month later. And in this case, we were able to see it just days after," said Noonan. "This is telling us something very important about the physics of what's happening at the comet's surface. We may be seeing the timescale it takes to form a substantial dust layer that can then be ejected by the gas."
The findings have been published in the journal Icarus.

Experiments Show Potatoes Can Survive In Lunar Solar (With Lots of Help) (science.org) 92

sciencehabit shares a report from Science.org: In The Martian, fictional astronaut Mark Watney survives the wasteland of Mars by growing potatoes in lunar soil -- with a bit of help from human poop. The idea may not be so far-fetched. In a preprint posted this month on bioRxiv, researchers show potatoes can indeed grow in the equivalent of Moon dust, though they need a lot of help from compost found on Earth. To make the discovery, scientists first had to re-create lunar regolith -- the loose, powdery layer that blankets the Moon's surface. To replicate that in the lab, David Handy, a space biologist at Oregon State University (OSU), and his colleagues used a mix of crushed minerals and volcanic ash that matched the chemistry of the Moon.

But lunar regolith is entirely devoid of the organic matter that plants need to grow. "Turning an inorganic, inhospitable bucket of glorified sand into something that can support plant growth is complex," says Anna-Lisa Paul, a plant molecular biologist at the University of Florida not involved with the work. So Handy and his colleagues added vermicompost -- organic waste from worms -- into the regolith. They found that a mix with 5% compost allowed the potatoes to grow while still emulating the stressful conditions of the lunar environment. After almost 2 months of growth, the team harvested the tubers, freeze-dried them, and ground them up for further testing.

Analysis of the potatoes' DNA showed stress-related genes had been activated. The potatoes also had higher concentrations of copper and zinc than Earth-grown ones, which may make them dangerous for human consumption. The plants' nutritional value, though, was similar to traditional potatoes -- a surprise to the scientists, who expected lower levels of nutrition "because the plants might have been working overtime to overcome certain stressors," Handy says.

Nvidia Announces Vera Rubin Space-1 Chip System For Orbital AI Data Centers 147

Nvidia unveiled its Vera Rubin Space-1 system for powering AI workloads in orbital data centers. "Space computing, the final frontier, has arrived," said CEO Jensen Huang. "As we deploy satellite constellations and explore deeper into space, intelligence must live wherever data is generated." CNBC reports: In a press release, the company said that its Vera Rubin Space-1 Module, which includes the IGX Thor and Jetson Orin, will be used on space missions led by multiple companies. The chips are specifically "engineered for size-, weight- and power-constrained environments." Partners include Axiom Space, Starcloud and Planet.

Huang said Nvidia is working with partners on a new computer for orbital data centers, but there are still engineering hurdles to overcome. "In space, there's no convection, there's just radiation," Huang said during his GTC keynote, "and so we have to figure out how to cool these systems out in space, but we've got lots of great engineers working on it."
