Earth Receives Laser-Beamed Message From 10 Million Miles Away (space.com) 31

Rahul Rao reports via Space.com: On Nov. 14, NASA picked up a laser signal fired from an instrument that launched with the Psyche spacecraft, which is currently more than 10 million miles (16 million kilometers) from Earth and heading toward a mysterious metal asteroid. (The spacecraft is at more than 40 times the average distance of Earth's moon, and still voyaging afar.) The moment marked the first successful test of NASA's Deep Space Optical Communications (DSOC) system, a next-generation comms link that sends information not by radio waves but instead by laser light. It's part of a series of tests NASA is doing to speed up communications in deep space, on different missions. "Achieving first light is a tremendous achievement. The ground systems successfully detected the deep space laser photons from DSOC," Abi Biswas, the system's project technologist at NASA's Jet Propulsion Laboratory (JPL) in Southern California, said in an agency statement.

"And we were also able to send some data, meaning we were able to exchange 'bits of light' from and to deep space," Biswas added.

FDA Considers First CRISPR Gene Editing Treatment That May Cure Sickle Cell 39

The U.S. Food and Drug Administration is reviewing a cutting-edge therapy called exa-cel that could potentially cure people of sickle cell disease, a painful and deadly disease with no universally successful treatment. "If approved, exa-cel, made by Boston-based Vertex Pharmaceuticals and the Swiss company CRISPR Therapeutics, would be the first FDA-approved treatment that uses genetic modification called CRISPR," reports CNN. From the report: CRISPR, or clustered regularly interspaced short palindromic repeats, is a technology researchers use to selectively modify DNA, the carrier of genetic information that the body uses to function and develop. [...] The new exa-cel treatment under FDA consideration can use the patient's own stem cells. Doctors would alter them with CRISPR to fix the genetic problems that cause sickle cell, and then the altered stem cells are given back to the patient in a one-time infusion.

In company studies, the treatment was considered safe, and it had a "highly positive benefit-risk for patients with severe sickle cell disease," Dr. Stephanie Krogmeier, vice president for global regulatory affairs with Vertex Pharmaceuticals Incorporated, told the panel. Thirty-nine of the 40 people tested with the treatment did not have a single vaso-occlusive crisis, which means the misshapen red blood cells block normal circulation and can cause moderate to severe pain. It's the top reason patients with sickle cell go to the emergency room or are hospitalized. Before the treatment, patients experienced about four of these painful crises a year, resulting in about two weeks in the hospital.

The FDA sought the independent panel's advice, in part, because this would be the first time the FDA would approve a treatment that uses CRISPR technology, but Dr. Fyodor Urnov, a professor in the Department of Molecular and Cell Biology at the University of California, Berkeley, reminded the committee CRISPR has been around for 30 years and, in that time, scientists have learned a lot about how to use it safely. "The technology is, in fact, ready for primetime," Urnov said. With this kind of genetic editing, scientists could inadvertently make a change to a patient's DNA that is off-target, and the therapy could harm the patient. [...] The FDA is expected to make an approval decision by December 8.

'Electrocaloric' Heat Pump Could Transform Air Conditioning (nature.com) 160

The use of environmentally damaging gases in air conditioners and refrigerators could become redundant if a new kind of heat pump lives up to its promise. A prototype, described in a study published last week in Science, uses electric fields and a special ceramic instead of alternately vaporizing a refrigerant fluid and condensing it with a compressor to warm or cool air. From a report: The technology combines a number of existing techniques and has "superlative performance," says Neil Mathur, a materials scientist at the University of Cambridge, UK. Emmanuel Defay, a materials scientist at the Luxembourg Institute of Science and Technology in Belvaux, and his collaborators built their experimental device out of a ceramic with a strong electrocaloric effect. Materials that exhibit this effect heat up when exposed to electric fields.

In an electrocaloric material, the atoms have an electric polarization -- a slight imbalance in their distribution of electrons, which gives these atoms a 'plus' and a 'minus' pole. When the material is left alone, the polarization of these atoms continuously swivels around in random directions. But when the material is exposed to an electric field, all the electrostatic poles suddenly align, like hair combed in one direction. This transition from disorder to order means that the electrons' entropy -- physicists' way of measuring disorder -- suddenly drops, Defay explains. But the laws of thermodynamics say that the total entropy of a system can never decline, so if it falls somewhere it must increase somewhere else. "The only possibility for the material to get rid of this extra mess is to pour it into the lattice" of its crystal structure, he says. That extra disorder means that the atoms themselves start vibrating faster, resulting in a rise in temperature.

A Viral Post on Social Media Will Clear the Medical Debt of Strangers (msn.com) 221

"To celebrate my life, I've arranged to buy up others' medical debt and then destroy the debt," reads a posthumous tweet posted Tuesday after the death of 38-year-old Casey McIntyre.

The Washington Post explains... McIntyre, who served as publisher at Razorbill, an imprint of Penguin Random House, was diagnosed in 2019 and proceeded through treatment without taking on debt, [husband Andrew Rose] Gregory told The Washington Post. But many fellow cancer patients she met were in more precarious financial positions, Gregory added. "We were both so keenly aware that Casey had great health insurance through Penguin Random House," said Gregory, 41. "Casey had no medical debt...."

About nine months before McIntyre died, her husband came across a video online about members of a North Carolina church who purchased nearly $3.3 million of local residents' medical debt for $15,048 in a "debt jubilee," a historical reference to ancient stories about personal debts being canceled at regular intervals. The couple chose to make monthly donations to RIP Medical Debt, the same organization that partnered with the North Carolina churchgoers. The nonprofit organization aims to abolish medical debt "at pennies on the dollar," according to its website. For every $100 donated, the company relieves $10,000 of medical debt. As of Saturday, nearly $200,000 had been donated to RIP Medical Debt in McIntyre's memory, which would wipe out approximately $20 million of unpaid medical bills. [By Sunday afternoon it had risen to over $334,000...]

Allison Sesso, president and chief executive of RIP Medical Debt, said her organization found out about McIntyre's case after McIntyre's posthumous social media post went viral. Sesso said the pace of donations was record-setting for her charity. "What an incredible gesture to the world as you're exiting," Sesso told The Post. "This final act of generosity is blowing up. The amount that they're raising and the rate at which this has gone is not something that we're used to."

McIntyre's post on X has now received 65,400 likes — and 3,086 reposts.

Archaeologists Unearth a Secret Lost Language From 3,000 Years Ago (sciencealert.com) 123

"And no, it's not COBOL," jokes long-time Slashdot reader schwit1, sharing this report from ScienceAlert: A secret text has been discovered in Türkiye, scattered among tens of thousands of ancient clay tablets, which were written in the time of the Hittite Empire during the second millennium BCE. No one yet knows what the curious cuneiform script says, but it seems to be a long-lost language from more than 3,000 years ago.

Experts say the mysterious idiom is unlike any other ancient written language found in the Middle East, although it seems to share roots with other Anatolian-Indo-European languages. The sneaky scrawlings start at the end of a cultic ritual text written in Hittite — the oldest known Indo-European tongue — after an introduction that essentially translates to: "From now on, read in the language of the country of Kalasma"... Currently, there are no available photos of the newly discovered tablet with Kalamaic writings, as experts are still working out how to translate it. Schwemer and his colleagues hope to publish their results along with images of their discovery sometime next year.

Could AI and Tech Advancements Bring a New Era of Evolution? (noemamag.com) 117

A professor of religion at Columbia University writes, "I do not think human beings are the last stage in the evolutionary process." Whatever comes next will be neither simply organic nor simply machinic but will be the result of the increasingly symbiotic relationship between human beings and technology. Bound together as parasite/host, neither people nor technologies can exist apart from the other because they are constitutive prostheses of each other... So-called "artificial" intelligence is the latest extension of the emergent process through which life takes ever more diverse and complex forms.
The article lists "four trajectories that will be increasingly important for the symbiotic relationship between humans and machines."

- Writing about neuroprosthetics, the professor argues that "Increasing possibilities for symbiotic relations between computers and brains will lead to alternative forms of intelligence that are neither human nor machinic, but something in between."

- Then there's biobots. The article argues that with nanotechnology, "it will be increasingly difficult to distinguish the natural from the artificial."

But there's also an interesting discussion about synthetic biology. "Michael Levin and his colleagues at the Allen Discovery Center of Tufts University — biologists, computer scientists and engineers — have created "xenobots," which are "biological robots" that were produced from embryonic skin and muscle cells from an African clawed frog." As Levin and his colleagues wrote in 2020...

Here we show a scalable pipeline for creating functional novel lifeforms: AI methods automatically design diverse candidate lifeforms in silico to perform some desired function, and transferable designs are then created using a cell-based construction toolkit to realize living systems with predicted behavior. Although some steps in this pipeline still require manual intervention, complete automation in the future would pave the way for designing and deploying living systems for a wide range of functions.

And the article concludes with a discussion of organic-relational AI: While Levin uses computational technology to create and modify biological organisms, the German neurobiologist Peter Robin Hiesinger uses biological organisms to model computational processes by creating algorithms that evolve. This work involves nothing less than developing a new form of "artificial" intelligence... Non-anthropocentric AI would not be merely an imitation of human intelligence, but would be as different from our thinking as fungi, dog and crow cognition is from human cognition.

Machines are becoming more like people and people are becoming more like machines. Organism and machine? Organism or machine? Neither organism nor machine? Evolution is not over; something new, something different, perhaps infinitely and qualitatively different, is emerging.

Who would want the future to be the endless repetition of the past?

SpaceX's Starship Reaches Outer Space Before Intentional Detonation (cnn.com) 125

CNN reports SpaceX made a second attempt to successfully launch Starship, the most powerful rocket ever constructed. The uncrewed rocket took off just after 7 a.m. CT (8 a.m. ET). The rocket took off as intended, making it roughly 8 minutes into flight before SpaceX confirmed it had to intentionally explode the Starship spacecraft as it flew over the ocean...

This mission comes after months of back-and-forth with federal regulators as SpaceX has awaited a launch license. The company is also grappling with pushback from environmentalists...

After separating from the Super Heavy rocket booster, the Starship spacecraft soared to an altitude of approximately 93 miles (150 kilometers) before SpaceX lost contact, according to a statement issued by the company. For context, the U.S. government considers 50 miles (80 kilometers) above Earth's surface the edge of outer space...

SpaceX is OK with rockets exploding in the early stages of development. That's because the company uses a completely different approach to rocket design than, say, NASA. The space agency focuses on building one rocket and strenuously designing and testing it on the ground before its first flight — taking years but all but guaranteeing success on the first launch. SpaceX, however, rapidly builds new prototypes and is willing to test them to their breaking point because there's usually a spare nearby. During a drive by the company's facilities on Friday — four Starship spacecraft and at least two Super Heavy boosters could be seen from public roadways.

CNN reminds readers that "so far in 2023 alone, the Falcon 9 has launched more than 70 spaceflights...

"Elon Musk described Starship as the vehicle that underpins SpaceX's founding purpose: sending humans to Mars for the first time. NASA has its own plans for the rocket."

Race Cannot Be Used To Predict Heart Disease, Scientists Say (nytimes.com) 97

Doctors have long relied on a few key patient characteristics to assess risk of a heart attack or stroke, using a calculus that considers blood pressure, cholesterol, smoking and diabetes status, as well as demographics: age, sex and race. Now, the American Heart Association is taking race out of the equation. From a report: The overhaul of the widely used cardiac-risk algorithm is an acknowledgment that, unlike sex or age, race identification in and of itself is not a biological risk factor. The scientists who modified the algorithm decided from the start that race itself did not belong in clinical tools used to guide medical decision making, even though race might serve as a proxy for certain social circumstances, genetic predispositions or environmental exposures that raise the risk of cardiovascular disease.

The revision comes amid rising concern about health equity and racial bias within the U.S. health care system, and is part of a broader trend toward removing race from a variety of clinical algorithms. "We should not be using race to inform whether someone gets a treatment or doesn't get a treatment," said Dr. Sadiya Khan, a preventive cardiologist at Northwestern University Feinberg School of Medicine, who chaired the statement writing committee for the American Heart Association, or A.H.A. The statement was published on Friday [PDF] in the association's journal, Circulation. An online calculator using the new algorithm, called PREVENT, is still in development.

Why Superconductor Research is in a 'Golden Age' - Despite Controversy (nature.com) 5

Davide Castelvecchi, writing for Nature: A Nature retraction last week has put to rest the latest claim of room-temperature superconductivity -- in which researchers said they had made a material that could conduct electricity without producing waste heat and without refrigeration. The retraction follows the downfall of an even more brazen claim about a supposed superconductor called LK-99, which went viral on social media earlier this year. Despite these high-profile setbacks, superconductivity researchers say the field is enjoying somewhat of a renaissance. "It's not a dying field -- on the contrary," says Lilia Boeri, a physicist who specializes in computational predictions at the Sapienza University of Rome. The progress is fuelled in part by the new capabilities of computer simulations to predict the existence and properties of undiscovered materials.

Much of the excitement is focused on 'super-hydrides -- hydrogen-rich materials that have shown superconductivity at ever-higher temperatures, as long as they are kept at high pressure. The subject of the retracted Nature paper was purported to be such a material, made of hydrogen, lutetium and nitrogen. But work in the past few years has unearthed several families of materials that could have revolutionary properties. "It really does look like we're on the hairy edge of being able to find a lot of new superconductors," says Paul Canfield, a physicist at Iowa State University in Ames and Ames National Laboratory.

Scientists Use Raspberry Pi Tech To Protect NASA Telescope Data (theregister.com) 38

Richard Speed reports via The Register: Scientists have revealed how data from a NASA telescope was secured thanks to creative thinking and a batch of Raspberry Pi computers. The telescope was the Super Pressure Balloon Imaging Telescope (SuperBIT), launched on April 16, 2023, from Wanaka Airport in New Zealand. The telescope was raised to approximately 33km in altitude by NASA's 532,000-cubic-meter (18.8-million-cubic-foot) balloon and, above circa 99.5 percent of the Earth's atmosphere, it spent over a month circumnavigating the globe and acquiring observations of astronomical objects. The plan had been for the payload to transmit its data to the ground using SpaceX's Starlink constellation and the US Tracking and Data Relay Satellite System (TDRSS). However, the Starlink connection went down soon after launch, on May 1, and the TDRSS connection became unstable on May 24. The boffins decided to attempt a landing on May 25 due to poor communications and concerns the balloon might be pulled away from further land crossings by weather.

The telescope itself was destroyed during the landing; it was dragged along the ground for 3km by a parachute that failed to detach, leaving a trail of debris in its wake. Miraculously, though, SuperBIT's solid-state drive was recovered intact. However, other than as a reference, its data was not needed thanks to the inclusion of Raspberry Pi-powered hardware in the form of four Data Recovery System (DRS) capsules. Each capsule included a Raspberry Pi 3B and 5TB of solid-state storage. A parachute, a Global Navigation Satellite System (GNSS) receiver, and an Iridium short-burst data transceiver were also included so the hardware could report its location to the recovery team. The capsules were connected to the main payload via Ethernet, and 24V DC was also available.

The plan had been to release the first DRS capsule on day 40, and then another every 20 days after that, whenever SuperBIT passed over land. However, when it became clear that SuperBIT would have to come down on May 25, it was decided to drop two DRS capsules over Argentina's Santa Cruz Province. Both of the DRS capsules released were recovered from their reported locations -- a curious cougar apparently nosed around one of them without causing damage -- and the data was fully intact. Of the unreleased DRS capsules, one failed for unknown reasons at launch -- the team speculated that perhaps a cable came loose -- but the other also contained an intact data set.

UK Approves World's First CRISPR-Based Medicine (theguardian.com) 21

Britain's drugs regulator has approved a groundbreaking treatment for two painful and debilitating lifelong blood disorders, which works by "editing" the gene that causes them. From a report: The Medicines and Healthcare products Regulatory Agency (MHRA) has given the green light for Casgevy to be used to treat sickle cell disease and beta thalassemia. It is the first medicine licensed anywhere that works by deploying gene editing that uses the "genetic scissors," known as CRISPR, for which its inventors won the Nobel prize for chemistry.

Casgevy's developers hope the pioneering treatment could banish the pain, infections and anaemia sickle cell disease brings and the severe anaemia experienced by those with beta thalassemia. About 15,000 people in the UK, almost all of African or Caribbean heritage, have sickle cell disease. About 1,000 -- mainly of Mediterranean, south Asian, south-east Asian and Middle Eastern background -- have beta thalassemia and need regular blood transfusions to treat their anaemia. Experts in the illnesses hope Casgevy may be a cure, making it no longer necessary for people with the conditions to have a bone marrow transplant. Until now this has been the only treatment available, even though the body can reject the donor marrow. The Sickle Cell Society welcomed the MHRA's decision as a "historic moment for the sickle cell community" which "offers [them] newfound hope and optimism."

FAA Clears SpaceX To Launch Second Starship Flight (cnbc.com) 19

The FAA has cleared SpaceX to launch its second spaceflight attempt of its Starship rocket. CNBC reports: SpaceX posted on the social media platform X shortly after the greenlight that it was "targeting Friday, November 17 for Starship's second flight test." A two-hour launch window will begin at 8 a.m. ET. SpaceX plans to livestream the Starship launch, with a webcast beginning about 30 minutes before lift off. Starship first launched in April, achieving flight for a few minutes before exploding mid-air, severely damaging the ground infrastructure and raising environmental concerns. The FAA in coordination with the U.S. Fish and Wildlife Service launched a safety review prior to issuing a new flight license for the second attempt.

FWS determined that the rocket launch and subsequent damage to the pad infrastructure had no long-term negative effects on the surrounding ecology, according to an agency report released Wednesday. Still, SpaceX will help mitigate damage to the area by reducing sound waves and vibrations, assisting in fire suppression, and providing launch pad protection, the agency said. As a result, "the FAA determined SpaceX met all safety, environmental, policy and financial responsibility requirements," the agency said in a statement Wednesday.

Global Decline In Male Fertility Linked To Common Pesticides 144

An anonymous reader quotes a report from NBC News: A prolonged decline in male fertility in the form of sperm concentrations appears to be connected to the use of pesticides, according to a study published Wednesday. Researchers compiled, rated and reviewed the results of 25 studies of certain pesticides and male fertility and found that men who had been exposed to certain classes of pesticides had significantly lower sperm concentrations. The study, published Wednesday in Environmental Health Perspectives, included data from more than 1,700 men and spanned several decades. "No matter how we looked at the analysis and results, we saw a persistent association between increasing levels of insecticide and decreases in sperm concentration," said study author Melissa Perry, who is an environmental epidemiologist and the dean of the College of Public Health at George Mason University. "I would hope this study would get the attention of regulators seeking to make decisions to keep the public safe from inadvertent, unplanned impacts of insecticides." [...]

Scientists have long suspected changes to the environment could be contributing, and they've been probing the role of pesticides for decades in studies of animals and in human epidemiology research. The new analysis focuses on two groups of chemicals -- organophosphates and some carbamates -- that are commonly used in insecticides. The researchers looked at data collected from groups of people with exposures to pesticides and others who were not. Most, but not all, of the research centered on exposures in the workplace. The researchers controlled for outside factors that could contribute to lower sperm counts like smoking and age. Perry said researchers aren't sure how pesticides are affecting sperm concentrations and more research will be needed.

It's likely that pesticides are one of many environmental factors that could be contributing to a decline in sperm concentrations. The trend of sperm concentration declines has been widely observed in studies around the world, but it's a complicated topic and some scientists still have reservations. Sperm are notoriously difficult to count and the technology to do so has changed over the years. There are many confounding factors that can affect male fertility, including age, obesity and opioid use, to name a few. Sperm concentrations are one important data point to consider, but other factors -- like how sperm are shaped and how they swim -- are also critical to male fertility. Perry said she hopes agencies like the Environmental Protection Agency begin to factor the impact of chemicals and pesticides on reproductive health in their assessments. "Given the body of evidence and these consistent findings, it's time to proactively reduce these insecticide exposures for men wanting to have families," Perry said.

Planet Where It Rains Sand Revealed By Nasa Telescope (theguardian.com) 22

Nasa's James Webb space telescope has revealed a planet where specks of sand fall as rain, in groundbreaking observations. From a report: The planet, Wasp-107b, lies 200 light years away in the Virgo constellation and had already caught the attention of astronomers because it is very large but very light, earning it the nickname the "candy floss" planet. The latest observations give an unprecedented glimpse of a strange and exotic world beyond our solar system that features silicate sand clouds and rain, scorching temperatures, raging winds and the distinct burnt-matches scent of sulphur dioxide. "Our knowledge of other planets is based on what we know from Earth," said Prof Leen Decin, of the Catholic Institute (KU) Leuven and first author of the research. "That's a very restricted knowledge."

The planet was discovered in 2017 after astronomers spotted a telltale periodic flickering of light from its host star each time the planet passed in front of it. "It's like a fly in front of a street lamp," said Decin. "You see a slight dimming of the light." James Webb takes these observations to the next level by measuring starlight that is filtered through the planet's atmosphere. Because different elements absorb different wavelengths of light, the spectrum of starlight indicates which gases are present. Wasp-107b is similar in mass to Neptune but almost the size of Jupiter, and its vast, diffuse nature allows the James Webb telescope to peer deep into its atmosphere.

Amazon To Stop Selling Seven Eyedrops After FDA Warning (nytimes.com) 22

Amazon said on Wednesday that it was removing seven eyedrops products from its website after the Food and Drug Administration warned the company that the eyedrops had not been recognized as safe and effective. From a report: The F.D.A. said in a letter to Andrew Jassy, Amazon's chief executive, on Monday that Amazon had violated federal regulations by selling the eyedrops, which claimed to help with problems including pink eye, dry eyes, eyestrain and floaters. "These products are especially concerning from a public health perspective," the F.D.A. letter said. "Ophthalmic drug products, which are intended for administration into the eyes, in general pose a greater risk of harm to users because the route of administration for these products bypasses some of the body's natural defenses."

The eyedrops named in the letter are: Similasan Pink Eye Relief, The Goodbye Company Pink Eye, Can-C Eye Drops, Optique 1 Eye Drops, OcluMed Eye Drops, TRP Natural Eyes Floaters Relief, and Manzanilla Sophia Chamomile Herbal Eye Drops. None of the eyedrops appeared to be available for purchase on Amazon on Wednesday morning. The company said in an emailed statement on Wednesday that "safety is a top priority."

Airbus Introduces 'Detumbler' Device To Address Satellite Tumbling In Low Earth Orbit (spacedaily.com) 23

Airbus has launched an innovative "detumbler" device designed to mitigate the risks posed by tumbling satellites in space. Space Daily reports: The Detumbler, a brainchild of Airbus and supported by the French Space Agency CNES under their Tech4SpaceCare initiative, was unveiled on Saturday, November 11. This magnetic damping device, weighing approximately 100 grams, is engineered to be attached to satellites nearing the end of their operational lives. Its purpose is to prevent these satellites from tumbling, a common issue in orbital flight dynamics, especially in LEO. The device features a central rotor wheel and magnets that interact with the Earth's magnetic field, effectively damping unwanted motion.

Airbus' development of the Detumbler commenced in 2021. Its operational principle is simple yet innovative. When a satellite functions normally, the rotor behaves akin to a compass, aligning with the Earth's magnetic field. However, if the satellite begins to tumble, the movement of the rotor induces eddy currents, creating a friction torque that dampens this motion. The design of the Detumbler involves a stator housing, complete with a bottom plate and top cover, along with the rotor comprising the central axle, rotor wheel, and magnets.

Tumbling satellites, particularly those in LEO, pose a significant challenge for future active debris removal missions. Dead satellites naturally tend to tumble due to orbital flight dynamics. The introduction of the Airbus Detumbler could revolutionize this scenario, making satellites easier to capture during debris-clearing missions and enhancing the overall safety and sustainability of space operations.
Airbus is expected to perform an in-orbit demonstration of the Detumbler in early 2024.

Lost NASA Tool Bag Can Be Seen With Binoculars (nbcnews.com) 74

A tool bag that astronauts accidentally let float away during a routine spacewalk at the International Space Station is now orbiting Earth and can be seen with a pair of binoculars. NBC News reports: The bag drifted away from the space station this month when NASA astronauts Jasmin Moghbeli and Loral O'Hara were performing maintenance on the exterior of the orbiting outpost. "During the activity, one tool bag was inadvertently lost," NASA officials wrote Nov. 1 in a blog post detailing the outcome of the spacewalk. "Flight controllers spotted the tool bag using external station cameras. The tools were not needed for the remainder of the spacewalk."

The bag is now circling the planet in low-Earth orbit, but NASA said there's little danger of the tools hitting the International Space Station. "Mission Control analyzed the bag's trajectory and determined that risk of recontacting the station is low and that the onboard crew and space station are safe with no action required," the agency said in the blog post. For now then, the lost tool bag has become a new artificial "star" in the night sky.
The tool bag is orbiting about a minute ahead of the space station and may be bright enough to see with a pair of binoculars. "Skywatchers who want to try to spot the tool bag in orbit should head out on a clear night and first determine when the International Space Station is passing overhead," reports NBC News. "The tool bag will likely remain visible in the night sky for a few months, before its orbit slowly degrades and it eventually falls toward Earth."

A Supernova 'Destroyed' Some of Earth's Ozone For a Few Minutes In 2022 53

An anonymous reader quotes a report from the New York Times: On Oct. 9, 2022, telescopes in space picked up a jet of high energy photons careening through the cosmos toward Earth, evidence of a supernova exploding 1.9 billion light-years away. Such events are known as gamma ray bursts, and astronomers who have continued studying this one said it was the "brightest of all time." Now, a team of scientists have discovered that this burst caused a measurable change in the number of ionized particles found in Earth's upper atmosphere, including ozone molecules, which readily absorb harmful solar radiation.

"The ozone was partially depleted -- was destroyed temporarily," said Pietro Ubertini, an astronomer at the National Institute of Astrophysics in Rome who was involved in discovering the atmospheric event. The effect was detectable for just a few minutes before the ozone repaired itself, so it was "nothing serious," Dr. Ubertini said. But had the supernova occurred closer to us, he said, "it would be a catastrophe." The discovery, reported Tuesday in a paper published in the journal Nature Communications, demonstrates how even explosions that occur far from our solar system can influence the atmosphere, which can be used as a giant detector for extreme cosmic phenomena.

To study the effects of last year's gamma ray burst on Earth, Dr. Ubertini and his colleagues looked for signals at the top of the ionosphere using data from the China Seismo-Electromagnetic Satellite, an orbiter designed to study changes in the atmosphere during earthquakes. They identified a sharp jump in the electric field at the top of the ionosphere, which they correlated to the gamma ray burst signal measured by the European Space Agency's International Gamma-Ray Astrophysics Laboratory, a mission that launched in 2002 to observe radiation from faraway celestial objects. The researchers found that the electric field rose by a factor of 60 as gamma rays ionized (essentially knocking away electrons from) ozone and nitrogen molecules high in the atmosphere. Once ionized, the molecule is unable to absorb any ultraviolet radiation, temporarily exposing Earth to more of the sun's damaging rays.

AI Could Predict Heart Attack Risk Up To 10 Years in the Future, Finds Oxford Study (theguardian.com) 21

AI could be used to predict if a person is at risk of having a heart attack up to 10 years in the future, a study has found. From a report: The technology could save thousands of lives while improving treatment for almost half of patients, researchers at the University of Oxford said. The study, funded by the British Heart Foundation (BHF), looked at how AI might improve the accuracy of cardiac CT scans, which are used to detect blockages or narrowing in the arteries.

Prof Charalambos Antoniades, chair of cardiovascular medicine at the BHF and director of the acute multidisciplinary imaging and interventional centre at Oxford, said: "Our study found that some patients presenting in hospital with chest pain -- who are often reassured and sent back home -- are at high risk of having a heart attack in the next decade, even in the absence of any sign of disease in their heart arteries. Here we demonstrated that providing an accurate picture of risk to clinicians can alter, and potentially improve, the course of treatment for many heart patients."

About 350,000 people in the UK have a CT scan each year but, according to the BHF, many patients later die of heart attacks due to their failure in picking up small, undetectable narrowings. Researchers analysed the data of more than 40,000 patients undergoing routine cardiac CT scans at eight UK hospitals, with a median follow-up time of 2.7 years. The AI tool was tested on a further 3,393 patients over almost eight years and was able to accurately predict the risk of a heart attack. AI-generated risk scores were then presented to medics for 744 patients, with 45% having their treatment plans altered by medics as a result.

Japan To Create $6.6 Billion Fund To Develop Outer Space Industry (japantimes.co.jp) 22

Japan plans to establish a new 1 trillion yen ($6.6 billion) fund to develop the country's outer space industry. "We believe it is a necessary fund to speed up our country's space development so we don't lag behind the increasingly intensifying international competition," Sanae Takaichi, minister in charge of space development, said in a news conference last week. The Japan Times reports: The fund will be allocated over a 10-year period for the Japan Aerospace Exploration Agency (JAXA), an Education, Culture, Sports, Science and Technology Ministry spokesperson said. Some 300 billion yen has been set aside for the fund in the latest supplementary budget approved by the Cabinet on Friday. The funding, which will support JAXA and the development of Japan's space industry, was a response to increased public and private sector focus on space activities.

Back in June, Tokyo unveiled a Space Basic Plan, detailing budgetary support for innovation in the private sector as an area of business growth. At the same time, it also unveiled a Space Security Initiative, which labeled space "a major arena for geopolitical competition for national power over diplomacy, defense, economic, and intelligence, as well as the science and technology and innovation that support these national powers."
