NASA Livestreams the Rocket That Will Carry Four Astronauts Around the Moon
science - Posted On:2026-01-17 13:45:00 Source: slashdot
"A mega rocket set to take astronauts around the Moon for the first time in decades is being taken to its launch pad," the BBC reported this morning. NASA is livestreaming their move of the 11-million-pound "stack" — which includes the Artemis II Space Launch System (SLS) rocket and the Orion spacecraft secured to it, all standing on its Mobile Launch Platform. Travelling at less than 1 mile per hour, the move is expected to take 12 hours. The mission — which could blast off as soon as 6 February — is expected to take 10 days. It is part of a wider plan aimed at returning astronauts to the lunar surface. As well as the rocket being ready, the Moon has to be in the right place too, so successive launch windows are selected accordingly. In practice, this means one week at the beginning of each month during which the rocket is pointed in the right direction followed by three weeks where there are no launch opportunities. The potential launch dates are: — 6, 7, 8, 10 and 11 February BR> — 6, 7, 8, 9 and 11 March BR> — 1, 3, 4, 5 and 6 April "The crew of four will travel beyond the far side of the moon, which could set a new record for the farthest distance humans have ever traveled from Earth, currently held by Apollo 13," reports CNN: But why won't Artemis II land on the lunar surface? "The short answer is because it doesn't have the capability. This is not a lunar lander," said Patty Casas Horn, deputy lead for Mission Analysis and Integrated Assessments at NASA. "Throughout the history of NASA, everything that we do is a bit risky, and so we want to make sure that that risk makes sense, and only accept the risk that we have to accept, within reason. So we build out a capability, then we test it out, then we build out a capability, then we test it out. And we will get to landing on the moon, but Artemis II is really about the crew..." The upcoming flight is the first time that people will be on board the Artemis spacecraft: The Orion capsule will carry the astronauts around the moon, and the SLS rocket will launch Orion into Earth orbit before the crew continues deeper into space... The mission will begin with two revolutions around Earth, before starting the translunar injection — the maneuver that will take the spacecraft out of Earth orbit and on toward the moon — about 26 hours into the flight, Horn said. "That's when we set up for the big burn — it's about six minutes in duration. And once we do this, you're on your way back to Earth. There's nothing else that you need to do. You're going to go by the moon, and the moon's gravity is going to pull you around and swing you back towards the Earth...." Avoiding entering lunar orbit keeps the mission profile simpler, allowing the crew to focus on other tasks as there is no need to pilot the spacecraft in any way. "The Artemis program's first planned lunar lander is called the Starship HLS, or Human Landing System, and is currently under development by SpaceX..." Read more of this story at Slashdot.
Managers on alert for “launch fever” as pressure builds for NASA’s Moon mission
Science - Posted On:2026-01-17 02:00:01 Source: arstechnica
KENNEDY SPACE CENTER, Florida—The rocket NASA is preparing to send four astronauts on a trip around the Moon will emerge from its assembly building on Florida's Space Coast early Saturday for a slow crawl to its seaside launch pad.
Riding atop one of NASA's diesel-powered crawler transporters, the Space Launch System rocket and its mobile launch platform will exit the Vehicle Assembly Building at Kennedy Space Center around 7:00 am EST (11:00 UTC). The massive tracked transporter, certified by Guinness as the world's heaviest self-propelled vehicle, is expected to cover the four miles between the assembly building and Launch Complex 39B in about eight to 10 hours.
The rollout marks a major step for NASA's Artemis II mission, the first human voyage to the vicinity of the Moon since the last Apollo lunar landing in December 1972. Artemis II will not land. Instead, a crew of four astronauts will travel around the far side of the Moon at a distance of several thousand miles, setting the record for the farthest humans have ever ventured from Earth.
Pesticides May Drastically Shorten Fish Lifespans, Study Finds
science - Posted On:2026-01-16 22:45:00 Source: slashdot
An anonymous reader quotes a report from the Guardian: Even low levels of common agricultural pesticides can stunt the long-term lifespan of fish, according to research led by Jason Rohr, a biologist at the University of Notre Dame in Indiana. Signs of aging accelerated when fish were exposed to the chemicals, according to the study, published in Science, which could have implications for other organisms. [...] The research found that fish from pesticide-affected lakes showed shortened telomeres, the caps at the end of chromosomes that are known as the biological clock for aging. When they shorten, it is a sign of cellular aging and a decline in the body's regenerative capacity. The lake populations consisted of younger fish, indicating that the pesticides contributed to shortened lives. Laboratory experiments confirmed the findings and showed chronic low-dose exposure reduced fish survival and degraded telomeres. These effects were not seen with acute high-dose exposure. Chemical analysis showed chlorpyrifos, which is banned in the UK and the EU but used in the US and China, was the only compound found in the fish tissues that was consistently associated with signs of aging. These included shortened telomeres and lipofuscin deposition -- a buildup of insoluble proteins often described as cellular "junk". The worrying aging effects occurred at concentrations below current US freshwater safety standards, Rohr said, suggesting the effects of chemicals and pesticides could be occurring at low levels over the long term. While short-term exposure to high doses did not appear to cause these aging issues -- though it did cause high toxicity and death in fish -- the researchers concluded that it was long-term exposure to low doses that drove the changes. The scientists added that reduced lifespan was particularly problematic because older fish often contribute disproportionately to reproduction, genetic diversity and population stability.

Archaeologists find a supersized medieval shipwreck in Denmark
Science - Posted On:2026-01-16 17:45:00 Source: arstechnica
Archaeologists recently found the wreck of an enormous medieval cargo ship lying on the seafloor off the Danish coast, and it reveals new details of medieval trade and life at sea.
Archaeologists discovered the shipwreck while surveying the seabed in preparation for a construction project for the city of Copenhagen, Denmark. It lay on its side, half-buried in the sand, 12 meters below the choppy surface of the Øresund, the straight that runs between Denmark and Sweden. By comparing the tree rings in the wreck’s wooden planks and timbers with rings from other, precisely dated tree samples, the archaeologists concluded that the ship had been built around 1410 CE.
Svaelget 2, as archaeologists dubbed the wreck (its original name is long since lost to history), was a type of merchant ship called a cog: a wide, flat-bottomed, high-sided ship with an open cargo hold and a square sail on a single mast. A bigger, heavier, more advanced version of the Viking knarrs of centuries past, the cog was the high-tech supertanker of its day. It was built to carry bulky commodities from ports in the Netherlands, north around the coast of Denmark, and then south through the Øresund to trading ports on the Baltic Sea—but this one didn’t quite make it.
Microplastics From Washing Clothes Could Be Hurting Your Tomatoes
science - Posted On:2026-01-16 16:00:00 Source: slashdot
A new study from Cornell and University of Toronto researchers has found that polyester microfibers shed from synthetic clothing during laundry can interfere with cherry tomato plant development [non-paywalled source] when these particles accumulate in agricultural soil. Plants grown in contaminated soil were 11% less likely to emerge, grew smaller and took several days longer to flower and ripen. Household laundry is a leading source of this contamination. Treated sewage sludge retains roughly 90% of microfibers from washers, and farmers in some countries apply this material to up to 75% of cropland as fertilizer. Some scientists have questioned the methodology. Willie Peijnenburg, a professor of environmental toxicology at Leiden University, told WaPo the microfiber concentration used was much higher than field observations. His research suggests plants primarily absorb microplastics through airborne particles entering leaf stomata rather than through soil. Read more of this story at Slashdot.
Astronauts Splash Down To Earth After Medical Evacuation From ISS
science - Posted On:2026-01-15 19:15:00 Source: slashdot
An anonymous reader quotes a report from the BBC: Four astronauts evacuated from the International Space Station (ISS) have landed back on Earth after their stay in space was cut short by a month due to a "serious" medical issue. The crew's captain, Nasa astronaut Mike Fincke, exited the spacecraft first, smiling and wobbling slightly on his feet before lying down on a gurney, following normal procedures. Nasa's Zena Cardman, Japan's Kimiya Yui and cosmonaut Oleg Platonov followed, waving and beaming at cameras. "It's so good to be home!", said Cardman. It is the first time astronauts have been evacuated due to a health issue since the station was put into Earth's orbit in 1998. The team, known as Crew-11, will now receive medical checks before being flown back to land after the splash down off the coast of California. In a news conference after splash-down, Nasa administrator Jared Isaacman said the sick astronaut is "fine right now" and in "good spirits." Judging by past Nasa communications about astronauts' health, it is unlikely that the identity of the crew member or details of the health issue will be released to the public. Control of the ISS has been handed over to Russian cosmonaut Sergey Kud-Sverchkov and two other crew members. The astronauts arrived on the ISS on August 1 expecting to complete a standard six and a half month stay. They were due to come home in mid-February. But last week, a scheduled spacewalk by Fincke and Cardman was called off at the last minute. Hours later, Nasa revealed a crew member had become ill. Read more of this story at Slashdot.
NASA’s first medical evacuation from space ends with on-target splashdown
Science - Posted On:2026-01-15 17:15:00 Source: arstechnica
Two Americans, a Japanese astronaut, and a Russian cosmonaut returned to Earth early Thursday after 167 days in orbit, cutting short their stay on the International Space Station by more than a month after one of the crew members encountered an unspecified medical issue last week.
The early homecoming culminated in an on-target splashdown in the Pacific Ocean off the coast of San Diego at 12:41 am PST (08:41 UTC) inside a SpaceX Crew Dragon spacecraft. The splashdown occurred minutes after the Dragon capsule streaked through the atmosphere along the California coastline, with sightings of Dragon's fiery trail reported from San Francisco to Los Angeles.
Four parachutes opened to slow the capsule for the final descent. Zena Cardman, NASA's commander of the Crew-11 mission, radioed SpaceX mission control moments after splashdown: "It feels good to be home, with deep gratitude to the teams who got us there and back."

Many People Who Come Off GLP-1 Drugs Regain Weight Within 2 Years, Review Suggests
science - Posted On:2026-01-15 13:15:00 Source: slashdot
Many people who stop using weight loss drugs will return to their previous weight within two years, a new review of existing research has found. CNN adds: This rate of weight regain is significantly faster than that seen in those who have lost weight by changing other lifestyle factors, such as diet and exercise, rather than relying on GLP-1 medications, researchers from the University of Oxford report in a paper published Wednesday in The BMJ journal. GLP-1, which stands for glucagon-like peptide-1, is a hormone naturally made by the body that helps signal to the brain and the gut that it's full and doesn't need to eat any more. Weight loss drugs mimic the action of this hormone by increasing the secretion of insulin to lower blood sugar. They also slow the movement of food through the digestive tract, which helps people feel full more quickly and for longer, and they work in the brain to reduce appetite.

AI Models Are Starting To Crack High-Level Math Problems
science - Posted On:2026-01-15 08:15:00 Source: slashdot
An anonymous reader quotes a report from TechCrunch: Over the weekend, Neel Somani, who is a software engineer, former quant researcher, and a startup founder, was testing the math skills of OpenAI's new model when he made an unexpected discovery. After pasting the problem into ChatGPT and letting it think for 15 minutes, he came back to a full solution. He evaluated the proof and formalized it with a tool called Harmonic -- but it all checked out. "I was curious to establish a baseline for when LLMs are effectively able to solve open math problems compared to where they struggle," Somani said. The surprise was that, using the latest model, the frontier started to push forward a bit. ChatGPT's chain of thought is even more impressive, rattling off mathematical axioms like Legendre's formula, Bertrand's postulate, and the Star of David theorum. Eventually, the model found a Math Overflow post from 2013, where Harvard mathematician Noam Elkies had given an elegant solution to a similar problem. But ChatGPT's final proof differed from Elkies' work in important ways, and gave a more complete solution to a version of the problem posed by legendary mathematician Paul Erdos, whose vast collection of unsolved problems has become a proving ground for AI. For anyone skeptical of machine intelligence, it's a surprising result -- and it's not the only one. AI tools have become ubiquitous in mathematics, from formalization-oriented LLMs like Harmonic's Aristotle to literature review tools like OpenAI's deep research. But since the release of GPT 5.2 -- which Somani describes as "anecdotally more skilled at mathematical reasoning than previous iterations" -- the sheer volume of solved problems has become difficult to ignore, raising new questions about large language models' ability to push the frontiers of human knowledge. Somani examined the online archive of more than 1,000 Erdos conjectures. Since Christmas, 15 Erdos problems have shifted from "open" to "solved," with 11 solutions explicitly crediting AI involvement. On GitHub, mathematician Terence Tao identifies eight Erdos problems where AI made meaningful autonomous progress and six more where it advanced work by finding and extending prior research, noting on Mastodon that AI's scalability makes it well suited to tackling the long tail of obscure, often straightforward Erdos problems. Progress is also being accelerated by a push toward formalization, supported by tools like the open-source "proof assistant" Lean and newer AI systems such as Harmonic's Aristotle.

The Swedish Start-Up Aiming To Conquer America's Full-Body-Scan Craze
science - Posted On:2026-01-14 22:45:00 Source: slashdot
An anonymous reader quotes a report from DealBook: Fifteen years ago, Daniel Ek broke into America's digital-content wars with his streaming music start-up, Spotify, which has turned into a publicly traded company with a $110 billion market value. Now he and his business partner, the Swedish entrepreneur Hjalmar Nilsonne, aim to crack a higher-stakes consumer market: American health care. The pair plan to bring Neko Health, the health tech start-up they founded in 2018, to New York this spring, DealBook is first to report. Mr. Ek and Mr. Nilsonne hope to capitalize on the growing number of prevention-minded Americans who are hungry to track their biometric data. Whether through wearables like Oura rings or more intensive screenings, consumers are turning to technology to improve their health and help spot the early onset of some big killers, including cardiovascular and metabolic diseases. The United States will be the third market, after Sweden and Britain, for Neko Health, which offers full-body diagnostic scans and is valued at roughly $1.7 billion. [...] Mr. Nilsonne and Mr. Ek said Neko Health's big aim was to change the health care model, in which spending across much of the developed world skyrockets but longevity gains have stalled. They want to make their noninvasive scans as routine as an annual checkup. The company, which advertises its service as "a health check for your future self," did not say what the U.S. scans would cost. But in Stockholm, an hourlong visit at one of its clinics costs 2,750 Swedish krona (about $300). Prenuvo's and Ezra's most comprehensive scans can cost $3,999. [...] Neko Health's technology differs from that of many of its U.S. rivals. It does not use M.R.I. or X-rays, instead relying on scores of sensors and cameras and a mix of proprietary and off-the-shelf technologies to measure heart function and circulation, and to photograph and map every inch of a patient's body looking for cancerous lesions. At the moment, the company's biggest challenge is scaling. [...] Mr. Nilsonne said Neko Health scans have detected the early onset of diseases or serious medical conditions for thousands of its patients. But the medical community is divided on the need for proactive screening technologies. The fear is that mass adoption could spur a wave of false positives and send healthy people to seek follow-up medical advice, overwhelming an already swamped health care system. Mr. Ek and Mr. Nilsonne believe they have built a better solution. And now they're ready to test it in the U.S. market. Read more of this story at Slashdot.
NASA Acknowledges Record Heat But Avoids Referencing Climate Change
science - Posted On:2026-01-14 15:15:00 Source: slashdot
An anonymous reader shares a report: Global temperatures soared in 2025, but a NASA statement published Wednesday alongside its latest benchmark annual report makes no reference to climate change, in line with President Donald Trump's push to deny the reality of planetary heating as a result of human activities. That marks a sharp break from last year's communications, issued under the administration of Democrat Joe Biden, which stated plainly: "This global warming has been caused by human activities" and has led to intensifying "heat waves, wildfires, intense rainfall and coastal flooding." Last year's materials also featured lengthy quotes from the then-NASA chief and a senior scientist and included graphics and a video. By contrast, this year's release only runs through a few key figures, and amounts to a handful of paragraphs. According to the US space agency, Earth's global surface temperature in 2025 was slightly warmer than in 2023 -- albeit within a margin of error -- making it effectively tied as the second-hottest year on record after 2024.

Scientists sequence a woolly rhino genome from a 14,400-year-old wolf’s stomach
Science - Posted On:2026-01-14 12:45:00 Source: arstechnica
A 14,400-year-old wolf puppy’s last meal is shedding light on the last days of one of the Ice Age’s most iconic megafauna species, the woolly rhinoceros.
When researchers dissected the frozen mummified remains of an Ice Age wolf puppy, they found a partially digested chunk of meat in its stomach: the remnants of the puppy’s last meal 14,400 years ago. DNA testing revealed that the meat was a prime cut of woolly rhinoceros, a now-extinct 2-metric-ton behemoth that once stomped across the tundras of Europe and Asia. Stockholm University paleogeneticist Sólveig Guðjónsdóttir and her colleagues recently sequenced a full genome from the piece of meat, which reveals some secrets about woolly rhino populations in the centuries before their extinction.
“Sequencing the entire genome of an Ice Age animal found in the stomach of another animal has never been done before,” said Uppsala University paleogeneticist Camilo Chacón-Duque, a coauthor of the study, in a recent press release.
NASA, Department of Energy To Develop Lunar Surface Reactor By 2030
science - Posted On:2026-01-14 05:15:00 Source: slashdot
NASA and the U.S. Department of Energy plan to deploy a nuclear fission reactor on the Moon by 2030 to provide continuous, long-duration power for lunar bases, science missions, and future Mars exploration. space & defense reports: NASA said fission surface power will provide a critical capability for long-duration missions by delivering continuous, reliable electrical power independent of sunlight, lunar night cycles or extreme temperature conditions. Unlike solar-based systems, a nuclear reactor could operate for years without refuelling, supporting habitats, science payloads, resource utilisation systems and surface mobility. NASA Administrator Jared Isaacman said achieving long-term human presence on the Moon and future missions to Mars will require new approaches to power generation. He said closer collaboration with the Department of Energy is essential to delivering the capabilities needed to support sustained exploration and infrastructure development beyond Earth orbit. The fission surface power system is expected to produce safe, efficient and scalable electrical power, forming a foundational element of NASA's Moon-to-Mars architecture. Continuous power availability is seen as a key enabler for permanent lunar bases, in-situ resource utilisation and expanded scientific operations in permanently shadowed regions.

Doubt Cast On Discovery of Microplastics Throughout Human Body
science - Posted On:2026-01-13 22:45:00 Source: slashdot
An anonymous reader quotes a report from the Guardian: High-profile studies reporting the presence of microplastics throughout the human body have been thrown into doubt by scientists who say the discoveries are probably the result of contamination and false positives. One chemist called the concerns "a bombshell." Studies claiming to have revealed micro and nanoplastics in the brain, testes, placentas, arteries and elsewhere were reported by media across the world, including the Guardian. There is no doubt that plastic pollution of the natural world is ubiquitous, and present in the food and drink we consume and the air we breathe. But the health damage potentially caused by microplastics and the chemicals they contain is unclear, and an explosion of research has taken off in this area in recent years. However, micro- and nanoplastic particles are tiny and at the limit of today's analytical techniques, especially in human tissue. There is no suggestion of malpractice, but researchers told the Guardian of their concern that the race to publish results, in some cases by groups with limited analytical expertise, has led to rushed results and routine scientific checks sometimes being overlooked. The Guardian has identified seven studies that have been challenged by researchers publishing criticism in the respective journals, while a recent analysis listed 18 studies that it said had not considered that some human tissue can produce measurements easily confused with the signal given by common plastics. There is an increasing international focus on the need to control plastic pollution but faulty evidence on the level of microplastics in humans could lead to misguided regulations and policies, which is dangerous, researchers say. It could also help lobbyists for the plastics industry to dismiss real concerns by claiming they are unfounded. While researchers say analytical techniques are improving rapidly, the doubts over recent high-profile studies also raise the questions of what is really known today and how concerned people should be about microplastics in their bodies.

EPA moves to stop considering economic benefits of cleaner air
Science - Posted On:2026-01-13 14:15:00 Source: arstechnica
If you were to do a cost-benefit analysis of your lunch, it would be pretty difficult to do the calculation without the sandwich. But it appears that the US Environmental Protection Agency (EPA) is moving in this same direction—removing the benefit—when it comes to air pollution regulations.
According to a New York Times report based on internal emails and documents—and demonstrated by a recently produced analysis on the EPA website—the EPA is changing its cost-benefit analysis process for common air pollutants. Instead of comparing the economic cost of a certain pollution limit to an estimate of the economic value of the resulting improvements in human health, the EPA will just qualitatively describe health benefits while carefully quantifying economic costs.
Cost-benefit analysis has been a key component of EPA regulations. Any decision to raise or lower air quality standards or pollution limits includes evaluations of the cost that change, like the addition of new pollution control equipment at power plants, would incur, for example.
You Can Now Reserve a Hotel Room On the Moon For $250,000
science - Posted On:2026-01-13 02:15:00 Source: slashdot
A newly founded startup called GRU Space is taking deposits of up to $1 million to eventually build inflatable hotels on the Moon. The bet is that space needs destinations, not just rockets, even if the first customers are essentially early adopters of sci-fi optimism. Ars Technica reports: It sounds crazy, doesn't it? After all, GRU Space had, as of late December when I spoke to founder Skyler Chan, a single full-time employee aside from himself. And Chan, in fact, only recently graduated from the University of California, Berkeley. [...] The GRU in the company's name, by the way, stands for Galactic Resource Utilization. The long-term vision is to derive resources from the Moon, Mars, asteroids, and beyond to fuel human expansion into space. If all that sounds audacious and unrealistic, well, it kind of is. But it is not without foundation. GRU Space has already received seed funding from Y Combinator, and it will go through the organization's three-month program early this year. This will help Chan refine his company's product and give him more options to raise money. Regarding his vision, you can read GRU Space's white paper here. Presently, the company plans to fly its initial "mission" in 2029 as a 10-kg payload on a commercial lunar lander, demonstrating an inflatable structure capability and converting lunar regolith into Moon bricks using geopolymers. With its second mission, the company plans to launch a larger inflatable structure into a "lunar pit" to test a scaled-up version of its resource development capabilities. The first hotel, an inflatable structure, would be launched in 2032 and would be capable of supporting up to four guests at a time. The next iteration beyond this would be the fancier structure, built from Moon bricks, in the style of the Palace of the Fine Arts. "SpaceX is building the FedEx to get us there, right?" Chan said. "But there has to be a destination worthy to stay in. Obviously, there is all kinds of debate around this, and what the future is going to be like. But our conviction is that the fundamental problem we have to solve, to advance humans toward the Moon and Mars, is off-world habitation. We can't keep everyone living on that first ship that sailed to North America, right? We have to build the roads and structures and offices that we live in today."

Switching water sources improved hygiene of Pompeii’s public baths
Science - Posted On:2026-01-12 16:15:00 Source: arstechnica
The eruption of Mount Vesuvius in 79 CE released thermal energy roughly equivalent to 100,000 times the atomic bombs dropped on Hiroshima and Nagasaki at the end of World War II, spewing molten rock, pumice, and hot ash over Pompeii. Pompeii's public baths, aqueduct, and water towers were among the preserved structures frozen in time. A new paper published in the Proceedings of the National Academy of Sciences analyzed calcium carbonate deposits from those structures to learn more about the city's water supply and how it changed over time.
Pompeii was founded in the sixth century BCE. Prior research revealed that, early on, the city relied on rainwater stored in cisterns and wells for its water supply. The public baths used weight-lifting machinery to lift water up well shafts that were as deep as 40 meters. As the city developed, so did the complexity of its water supply system, most notably with the construction of an aqueduct between 27 BCE and 14 CE.
The authors of this latest paper were interested in the calcium carbonate deposits left by water in well shafts as well as the baths and aqueduct. The different layers have "different chemical and isotope composition, calcite crystal size, and shape," which in turn could reveal information about seasonal changes in temperature, as well as changes over time in the chemical composition of the water. Analyzing those properties would enable them to "reconstruct the history of such systems—particularly public baths—revealing aspects of their maintenance and the adaptations made during their period of use," the authors wrote.
NASA launches new mission to get the most out of the James Webb Space Telescope
Science - Posted On:2026-01-12 14:45:01 Source: arstechnica
Among other things, the James Webb Space Telescope is designed to get us closer to finding habitable worlds around faraway stars. From its perch a million miles from Earth, Webb's huge gold-coated mirror collects more light than any other telescope put into space.
The Webb telescope, launched in 2021 at a cost of more than $10 billion, has the sensitivity to peer into distant planetary systems and detect the telltale chemical fingerprints of molecules critical to or indicative of potential life, like water vapor, carbon dioxide, and methane. Webb can do this while also observing the oldest observable galaxies in the Universe and studying planets, moons, and smaller objects within our own Solar System.
Naturally, astronomers want to get the most out of their big-budget observatory. That's where NASA's Pandora mission comes in.
Revolutionary Eye Injection Saved My Sight, Says First-Ever Patient
science - Posted On:2026-01-12 13:15:00 Source: slashdot
Doctors say they have achieved the previously impossible -- restoring sight and preventing blindness in people with a rare but dangerous eye conditon called hypotony. From a report: Moorfields hospital in London is the world's first dedicated clinic for the disorder and seven out of eight patients given the pioneering treatment have responded to the therapy, a pilot study shows. One of them -- the first-ever -- is Nicki Guy, 47, who is sharing her story exclusively with the BBC. She says the results are incredible: "It's life-changing. It's given me everything back. I can see my child grow up. "I've gone from counting fingers and everything being really blurry to being able to see." Currently, she can see and read most lines of letters on an eye test chart. She is one line away from what is legally required for driving - a massive change from being partially sighted, using a magnifying glass for anything close up and having to navigate around the house and outside largely using memory. "If my vision stays like this for the rest of my life it would be absolutely brilliant. I may not ever be able to drive again but I'll take that!" she says. With hypotony, pressure within the eyeball becomes dangerously low, leading it to cave in on itself. Read more of this story at Slashdot.
