NASA is putting a team together to study unidentified aerial phenomena, popularly known as UFOs, the US space agency said Thursday. From a report: The team will gather data on "events in the sky that cannot be identified as aircraft or known natural phenomena -- from a scientific perspective," the agency said. NASA said it was interested in UAPs from a security and safety perspective. There was no evidence UAPs are extraterrestrial in origin, NASA added. The study is expected to take nine months. "NASA believes that the tools of scientific discovery are powerful and apply here also," said Thomas Zurbuchen, the associate administrator for science at NASA Headquarters in Washington, DC. "We have access to a broad range of observations of Earth from space -- and that is the lifeblood of scientific inquiry. We have the tools and team who can help us improve our understanding of the unknown. That's the very definition of what science is. That's what we do."

Google Cloud developer advocate Emma Haruka Iwao and her colleagues say they've calculated Pi to 100 trillion digital decimal places. Engadget reports: Iwao and her team previously set the record in 2019 when they carried out a calculation to an accuracy of 31.4 trillion digits. The benchmark has been broken a few times since then [...]. In a blog post, Iwao wrote that finding as many digits of Pi as possible is a way to measure the progress of compute power. Her job involves showing off what Google Cloud is capable of, so it's not too surprising that Iwao tapped into the power of the platform to perform the calculation.

In 2019, the calculation (which figured out a third as many digits as the most recent attempt) took 121 days. This time around, the calculation ran for 157 days, 23 hours, 31 minutes and 7.651 seconds, meaning the computers were running more than twice as quickly despite Iwao using "the same tools and techniques." Around 82,000 terabytes of data were processed overall. Iwao also notes that reading all 100 trillion digits out loud at a rate of one per second would take more than 3.1 million years. And in case you're wondering, the 100-trillionth decimal place of Pi is 0.

Researchers have discovered a new particle that is a magnetic relative of the Higgs boson. Whereas the discovery of the Higgs boson required the tremendous particle-accelerating power of the Large Hadron Collider (LHC), this never-before-seen particle -- dubbed the axial Higgs boson -- was found using an experiment that would fit on a small kitchen countertop. Live Science reports: As well as being a first in its own right, this magnetic cousin of the Higgs boson -- the particle responsible for granting other particles their mass -- could be a candidate for dark matter, which accounts for 85%t of the total mass of the universe but only reveals itself through gravity. The axial Higgs boson differs from the Higgs boson, which was first detected by the ATLAS and CMS detectors at the LHC a decade ago in 2012, because it has a magnetic moment, a magnetic strength or orientation that creates a magnetic field. As such, it requires a more complex theory to describe it than its non-magnetic mass-granting cousin. [...]

"When my student showed me the data I thought she must be wrong," Kenneth Burch, a professor of physics at Boston College and lead researcher of the team that made the discovery, told Live Science. "It's not every day you find a new particle sitting on your tabletop." [...] "We found the axial Higgs boson using a tabletop optics experiment which sits on a table measuring about 1 x 1 meters by focusing on a material with a unique combination of properties," Burch continued. "Specifically we used rare-earth Tritelluride (RTe3) [a quantum material with a highly 2D crystal structure]. The electrons in RTe3 self-organize into a wave where the density of the charge is periodically enhanced or reduced." The size of these charge density waves, which emerge above room temperature, can be modulated over time, producing the axial Higgs mode.

In the new study, the team created the axial Higgs mode by sending laser light of one color into the RTe3 crystal. The light scattered and changed to a color of lower frequency in a process known as Raman scattering, and the energy lost during the color change created the axial Higgs mode. The team then rotated the crystal and found that the axial Higgs mode also controls the angular momentum of the electrons, or the rate at which they move in a circle, in the material meaning this mode must also be magnetic. "Originally we were simply investigating the light scattering properties of this material. When carefully examining the symmetry of the response -- how it differed as we rotated the sample -- we discovered anomalous changes that were the initial hints of something new," Burch explained. "As such, it is the first such magnetic Higgs to be discovered and indicates the collective behavior of the electrons in RTe3 is unlike any state previously seen in nature." The report notes that this is also the first time scientists have observed a state with multiple broken symmetries.

"Symmetry breaking occurs when a symmetric system that appears the same in all directions becomes asymmetric," reports Live Science. "Oregon University suggests thinking of this as being like a spinning coin that has two possible states. The coin eventually falls onto its head or tail face thus releasing energy and becoming asymmetrical."

The findings have been published in the journal Nature.

A small NYC-led cancer trial has achieved a result reportedly never before seen - the total remission of cancer in all of its patients. From a report: To be sure, the trial -- led by doctors at Memorial Sloan Kettering and backed by drug maker GlaxoSmithKline -- has only completed treatment of 12 patients, with a specific cancer in its early stages and with a rare mutation as well. But the results, reported Sunday in the New England Journal of Medicine and the New York Times, were still striking enough to prompt multiple physicians to tell the paper they were believed to be unprecedented. One cancer specialist told the Times it was an "unheard-of" result. According to the NEJM paper and the Times report, all 12 patients had rectal cancer that had not spread beyond the local area, and their tumors all exhibited a mutation affecting the ability of cells to repair damage to DNA.

British researchers have developed a biodegradable gel to repair damage caused by a heart attack in a breakthrough that could improve the health of millions of survivors worldwide. The Guardian reports: Now after years of efforts searching for solutions to help the heart repair itself, researchers at the University of Manchester have created a gel that can be injected directly into the beating heart -- effectively working as a scaffold to help injected cells grow new tissue. Until now, when cells have been injected into the heart to reduce the risk of heart failure, only 1% have stayed in place and survived. But the gel can hold them in place as they graft on to the heart.

To prove the technology could work, researchers showed the gel can support growth of normal heart muscle tissue. When they added human cells reprogrammed to become heart muscle cells into the gel, they were able to grow in a dish for three weeks and the cells started to spontaneously beat. Echocardiograms (ultrasounds of the heart) and electrocardiograms (ECGs, which measure the electrical activity of the heart) on mice confirmed the safety of the gel. To gain more knowledge, researchers will test the gel after mice have a heart attack to show they develop new muscle tissue. The study is being presented at the British Cardiovascular Society conference in Manchester.

An anonymous reader quotes a report from Phys.Org: Researchers in Australia have been able to use trace amounts of liquid platinum to create cheap and highly efficient chemical reactions at low temperatures, opening a pathway to dramatic emissions reductions in crucial industries. When combined with liquid gallium, the amounts of platinum required are small enough to significantly extend the earth's reserves of this valuable metal, while potentially offering more sustainable solutions for CO2 reduction, ammonia synthesis in fertilizer production, and green fuel cell creation, together with many other possible applications in chemical industries. These findings, which focus on platinum, are just a drop in the liquid metal ocean when it comes to the potential of these catalysis systems. By expanding on this method, there could be more than 1,000 possible combinations of elements for over 1,000 different reactions.

Platinum is very effective as a catalyst (the trigger for chemical reactions) but is not widely used at industrial scale because it's expensive. Most catalysis systems involving platinum also have high ongoing energy costs to operate. Normally, the melting point for platinum is 1,700C. And when it's used in a solid state for industrial purposes, there needs to be around 10% platinum in a carbon-based catalytic system. It's not an affordable ratio when trying to manufacture components and products for commercial sale. That could be set to change in the future, though, after scientists at UNSW Sydney and RMIT University found a way to use tiny amounts of platinum to create powerful reactions, and without expensive energy costs.

The team, including members of the ARC Center of Excellence in Exciton Science and the ARC Center of Excellence in Future Low Energy Technologies, combined the platinum with liquid gallium, which has a melting point of just 29.8C -- that's room temperature on a hot day. When combined with gallium, the platinum becomes soluble. In other words, it melts, and without firing up a hugely powerful industrial furnace. For this mechanism, processing at an elevated temperature is only required at the initial stage, when platinum is dissolved in gallium to create the catalysis system. And even then, it's only around 300C for an hour or two, nowhere near the continuous high temperatures often required in industrial-scale chemical engineering. The results have been published in the journal Nature Chemistry.

Anyone who has more money than they know what to do with eventually tries to cure aging. Google founder Larry Page has tried it. Jeff Bezos has tried it. Tech billionaires Larry Ellison and Peter Thiel have tried it. Now the kingdom of Saudi Arabia, which has about as much money as all of them put together, is going to try it. From a report: The Saudi royal family has started a not-for-profit organization called the Hevolution Foundation that plans to spend up to $1 billion a year of its oil wealth supporting basic research on the biology of aging and finding ways to extend the number of years people live in good health, a concept known as "health span." The sum, if the Saudis can spend it, could make the Gulf state the largest single sponsor of researchers attempting to understand the underlying causes of aging -- and how it might be slowed down with drugs. The foundation hasn't yet made a formal announcement, but the scope of its effort has been outlined at scientific meetings and is the subject of excited chatter among aging researchers, who hope it will underwrite large human studies of potential anti-aging drugs.

The fund is managed by Mehmood Khan, a former Mayo Clinic endocrinologist and the onetime chief scientist at PespsiCo, who was recruited to the CEO job in 2020. "Our primary goal is to extend the period of healthy lifespan," Khan said in an interview. "There is not a bigger medical problem on the planet than this one." The idea, popular among some longevity scientists, is that if you can slow the body's aging process, you can delay the onset of multiple diseases and extend the healthy years people are able to enjoy as they grow older. Khan says the fund is going to give grants for basic scientific research on what causes aging, just as others have done, but it also plans to go a step further by supporting drug studies, including trials of "treatments that are patent expired or never got commercialized."

"NASA's DAVINCI mission to Venus is scheduled for launch in 2029," reports Gizmodo, adding that a new paper "details this upcoming journey, a daring mission that could shed new light on the scorching hot planet's mysterious, and potentially habitable, past." Upon its arrival at the second planet from the Sun, the probe will plunge through Venus' atmosphere, ingesting its gases for approximately one hour before landing on the planet's surface, according to the paper published in The Planetary Science Journal. DAVINCI is designed to act as a flying chemistry lab, and it will use its built-in instruments to analyze Venus's atmosphere, temperatures, pressure and wind speed, while taking a few photos of its trip through planetary hell...

If it survives the atmospheric entry, the probe will — hopefully — land in the Alpha Regio mountains, which are roughly the size of Texas, according to the researchers behind the new paper. Under ideal conditions, the probe will operate for 17 to 18 minutes once it sticks the landing, but it isn't really required to operate on Venus since all the precious data will have already been collected during its atmospheric plunge.
Digital Trends calls Venus "a frontier in planetary science about which very little is known" — then explains why that is. The biggest issue for any potential mission to Venus is the heat, as the surface temperatures can be as high as 900 degrees Fahrenheit (475 degrees Celsius). That's hot enough to melt lead, and it wreaks havoc with electronics... The pressure at the surface is around 95 bars, or nearly 100 times the atmospheric pressure on Earth's surface, so engineering a probe for this kind of environment is kind of like building a submarine... To keep the probe active for as long as possible, it is spherical and covered in a thick titanium shell to withstand the pressure and insulate against the heat. Then there's more insulation inside this shell, made of special materials including astroquartz, a type of fiber made from fused quartz... It's then filled with carbon dioxide gas to protect the high-voltage electronics from sparking and to stop any Earth gases from leaking in during launch....

The descent sphere will also have a camera that will be snapping high-contrast images of the surface, which can then be built up into 3D maps. For a camera to operate from inside a metal sphere, though, you need a window. And glass isn't a great material for dealing with intensely high-pressure environments. That's why DAVINCI's window will be made not of glass but sapphire... "Our final images will have 10-centimeter resolution," said the team's principal investigator, Jim Garvin. "That's the scale you'd see looking out across your living room...."

Researchers know that the clouds of Venus have drops of sulfuric acid in them — and sulfuric acid eats through materials. It's a particular concern for the Kevlar lanyard that will attach the descent sphere to the parachute. So to test whether the lanyard can withstand the acidic environment, the engineers don't just suspend it in a few drops of acid — they coat the entire surface in acid, then test the lanyard's pull strength to make sure it can survive long enough to take the probe through the atmosphere even in the worst possible case.
SciTechDaily notes DAVINCI "is the first mission to study Venus using both spacecraft flybys and a descent probe....

"It will also provide the first descent imaging of the mountainous highlands of Venus while mapping their rock composition and surface relief at scales not possible from orbit."

"Venus crossed the sun's face 10 years ago today," writes Space.com. "Most people alive will never see the sight again."

Long-time Slashdot reader davidwr is still thinking about it: Slashdot, what are your memories of the 2012 or 2004 transits? What about other celestial events that you probably won't live long enough to see again?
At Space.com, astronomer Tom Kress points out Mercury transits are more common, occurring about 13 times each century — and supplies some context (along with some cool photos): In 1639, English astronomer Jeremiah Horrocks had improved on Kepler's tables using his own observations and aptitude for mathematics. He predicted a transit of Venus in December of that year with just a few weeks' notice, and sure enough it occurred. Kepler had miscalculated, and Horrocks became one of the only people in the world to have seen a transit of Venus....

Only six Venus transits have occurred since: in 1761 (as predicted by Kepler), 1769, 1874, 1882, 2004 and 2012. They come in pairs separated by eight years, but with more than a century between each set. The next transit won't occur until 2117 and, with this in mind, I made every effort to witness the entirety of the last one 10 years ago....

Shortly after noon local time, the black edge of the silhouette of Venus emerged on the face of the sun... A chorus of vocal awe erupted across the crowd of skywatchers, culminating in cheers of excitement as Venus' night-side began its rapid ingress onto the disk of the sun — a process that took just over 15 minutes....

I couldn't help but feel closer to Venus than I really was, standing on a huge terrestrial volcano and looking out at the most volcanic planet in the solar system.

"In molecular biologist David Sinclair's lab at Harvard Medical School, old mice are growing young again," reports CNN: Using proteins that can turn an adult cell into a stem cell, Sinclair and his team have reset aging cells in mice to earlier versions of themselves. In his team's first breakthrough, published in late 2020, old mice with poor eyesight and damaged retinas could suddenly see again, with vision that at times rivaled their offspring's.

"It's a permanent reset, as far as we can tell, and we think it may be a universal process that could be applied across the body to reset our age," said Sinclair, who has spent the last 20 years studying ways to reverse the ravages of time.

"If we reverse aging, these diseases should not happen. We have the technology today to be able to go into your hundreds without worrying about getting cancer in your 70s, heart disease in your 80s and Alzheimer's in your 90s." Sinclair told an audience at Life Itself, a health and wellness event presented in partnership with CNN.

"This is the world that is coming. It's literally a question of when and for most of us, it's going to happen in our lifetimes," Sinclair told the audience.... Sinclair said his lab has reversed aging in the muscles and brains of mice and is now working on rejuvenating a mouse's entire body.
The article points out that he's building on research by Japan's Dr. Shinya Yamanaka (which in 2007 won a Nobel prize).

But one key caveat: "Studies on whether the genetic intervention that revitalized mice will do the same for people are in early stages, Sinclair said. It will be years before human trials are finished, analyzed and, if safe and successful, scaled to the mass needed for a federal stamp of approval."

"We have reestablished reliable communications with Ingenuity," reported the team lead for NASA's Mars helicopter, Teddy Tzanetos, in a blog post last week. As detailed in our last blog post, for the first time in our yearlong extended mission we had a loss of communications with Ingenuity from the downlink of May 3 (Sol 427) and May 4 (Sol 428). After a week of anomaly investigation, two sols dedicated to data collection, and the heroic efforts of the Perseverance and Ingenuity operations teams, I am very happy to report that we have reestablished reliable communications with Ingenuity.

Based on all available telemetry, the helicopter appears healthy, and we have resumed a modified form of operations. Assuming winter recommissioning activities complete nominally, Ingenuity's 29th flight may occur in the next few sols.... All telemetry downlinked so far suggests that Ingenuity is healthy, with no signs of damage from the overnight cold cycles.
That's the good news.

The bad news? Telemetry from Ingenuity confirmed that the loss of communications was due to insufficient battery state-of-charge (SOC) going into the night, which resulted in a reset of our mission clock. This daily state-of-charge deficit is likely to persist for the duration of Martian winter (until September/October).

Challenges like these are to be expected: After hundreds of sols and dozens of flights beyond the five flights originally planned, the solar-powered helicopter is in uncharted terrain. We are now operating far outside our original design limits. Historically, Mars is very challenging for spacecraft (particularly solar-powered spacecraft). Each sol could be Ingenuity's last....

We have reached the point in Martian late fall/early winter at which Ingenuity can no longer support the energy demands of nominal operations. Starting on the evening of Sol 426, we believe Ingenuity started experiencing overnight battery brownouts (drops in the battery's voltage), which reset the electronics. Due to the seasonal decrease in available solar energy, increases in airborne dust density, and the drop in temperatures, the energy demand to keep the electronics powered and warm throughout the night has surpassed Ingenuity's available energy budget.... We expect to be in this challenging winter energy paradigm until around Sol 600, at which point we expect to return to being power-positive from sol to sol.
The blog post says NASA can cope with a resetting mission clock. But the helicopter's battery (and other electronics) are now facing overnight ambient temperatures of about minus 80 degrees C (minus 112 degrees F), "a lifetime risk to our electronic components." Although component failure has always been a risk that we have carried since rover deployment, that risk is now magnified... We do have limited electronics core module (ECM) component testing to suggest that select components may survive through the winter, but we cannot predict how the entire ECM will fare throughout winter. Cold-soaking electronics is believed to have caused the end of the Opportunity and Spirit Mars rover missions.

Given our elevated risk posture, our focus in the last several sols has been to prioritize data downlink from Ingenuity to the Helicopter Base Station (HBS). We have a handful of Heli-to-HBS transfer activities left before all unique data are copied from Ingenuity to the HBS. Specifically, we are copying flight performance logs, electronics logs, and high-resolution color images from the last eight flights that are still onboard Ingenuity.

After all critical logs are transferred, the team will proceed with a recommissioning phase during which we will reestablish Ingenuity's flight-readiness given our ongoing overnight cold-cycling. Like during the technology demonstration phase, we will perform a high-speed spin before proceeding to flight. Should Ingenuity receive a clean bill of health, we would be ready to execute a short sortie to the southwest in Flight 29. This flight will improve our radio link for approximately the next four to six months while Perseverance samples at the river delta.

In the meantime, the Ingenuity flight software team will be preparing a series of upgrades to enable advanced navigation features. These new capabilities will help Ingenuity ascend the river delta and continue its missions as a forward scout for Perseverance past winter.
Mashable notes that Ingenuity recently sent back new footage showing its April 8th flight — calling it Ingenuity's "farthest and fastest flight yet." Flying 33 feet above the surface of Mars on April 8, "it traveled 2,310 feet — a bit less than half a mile — at 12 mph." The whole record-breaking feat lasted a little over 2.5 minutes, but that's much longer than its first flight of 39 seconds in the spring of 2021. NASA increased the new video's speed fivefold, reducing its runtime to less than 35 seconds.

Last summer Chinese market analyst Ming-Chi Kuo reported the iPhone 13 would include satellite communication capability, remembers long-time tech pundit Robert Cringley, who adds that the prediction was denied by Apple. "This, in itself, was weird because Apple generally doesn't react to rumors. But beyond the mere reaction, the way Apple responded to Ming's prediction was especially odd." An unattributed leak from Cupertino said that the iPhone 13 definitely would not include satellite communication capability. And even if some iPhone could communicate with satellites, the leak continued, it wouldn't be offering satellite voice service (which Ming had mentioned), limiting iPhones to satellite text or iMessage.... This was making less and less sense, but it clearly meant there was something happening.

Then came the iPhone 13 launch and Ming was wrong for a change — no satellite communications. So the Cupertino rumor mill went about its business, Ming's satellite rumor apparently forgotten.

But not by me....
And this leads Cringley to another prediction of his own: I am convinced an announcement will be coming soon. Apple will shortly enter the satellite business by acquiring GlobalStar and its 24 satellites. They will use those 24, plus 24 more satellites that Apple has already commissioned, to offer satellite service for iMessage and Apple's Find My network just like they implied in their denial last year.

These apps are proxies for Apple entering — and then dominating — the Internet of Things (IoT) business. After all, iPhones will give them 1.6 billion points of presence for AirTag detection even on sailboats in the middle of the ocean — or on the South Pole.

IoT is already a big business that is going to get even bigger even faster because of Apple. Adding that satellite connection to iMessage and Find My offers the possibility of ubiquity for IoT, though only on Apple's network. Ubiquity (being able to track anything in near real time anywhere on the planet) signals the maturity of IoT, turning it quickly into a $1 TRILLION business — in this case Apple's $1 TRILLION business....

While Apple's stated goals will be only iMessage and Find My, followed by IoT, in the longer run Cupertino plans to dis-intermediate the mobile carriers — becoming themselves a satellite-based global phone and data company. That will require shifting over additional Globalstar bandwidth plus launching another 300-600 satellites, so it is several years away but IS coming. Apple will compete not just with every other mobile carrier including Cupertino's own customers, they will also compete with satellite Internet providers like Starlink, OneWeb, and Amazon's Kuiper. Apple can compete with Starlink with so many fewer satellites because GlobalStar has vastly more licensed spectrum than does SpaceX, which has to reuse the same spectrum over and over again with thousands of satellites.

NASA said this week that it plans to purchase five additional Crew Dragon missions from SpaceX to carry astronauts to the International Space Station. Ars Technica reports: Although the space agency's news release does not specifically say so, these may be the final flights NASA needs to keep the space station fully occupied into the year 2030. As of now, there is no signed international agreement to keep the station flying until then, but this new procurement sends a strong signal that the space agency expects the orbital outpost to keep flying that long.

The announcement also suggests that SpaceX will fly more than twice as many crews to the space station than the other partner in NASA's commercial crew program, Boeing. Under the new agreement, SpaceX would fly 14 crewed missions to the station on Crew Dragon, and Boeing would fly six during the lifetime of the station.

An anonymous reader quotes a report from the New York Times: A 20-year-old woman who was born with a small and misshapen right ear has received a 3-D printed ear implant made from her own cells, the manufacturer announced on Thursday. Independent experts said that the transplant, part of the first clinical trial of a successful medical application of this technology, was a stunning advance in the field of tissue engineering. The new ear was printed in a shape that precisely matched the woman's left ear, according to 3DBio Therapeutics, a regenerative medicine company based in Queens. The new ear, transplanted in March, will continue to regenerate cartilage tissue, giving it the look and feel of a natural ear, the company said.

The results of the woman's reconstructive surgery were announced by 3DBio in a news release. Citing proprietary concerns, the company has not publicly disclosed the technical details of the process, making it more difficult for outside experts to evaluate. The company said that federal regulators had reviewed the trial design and set strict manufacturing standards, and that the data would be published in a medical journal when the study was complete. The clinical trial, which includes 11 patients, is still ongoing, and it's possible that the transplants could fail or bring unanticipated health complications. But since the cells originated from the patient's own tissue, the new ear is not likely to be rejected by the body, doctors and company officials said.

It's a trait best seen in the eager pub quizzer -- a tendency to leap to an answer without a shadow of a doubt. Now researchers have suggested that while people who have little difficulty making decisions are more confident in their choices, they are no more accurate than those who feel more torn. From a report: Writing in the journal Plos One, researchers revealed how they conducted experiments to explore potential differences between people who tend to be decisive, known as action-oriented people, and those who struggle to commit to a choice, known as state-oriented people. "What we found is that confidence was the only thing that was different," said Dr Wojciech Zajkowski, the first author of the research, who is now based at the Riken social decision science laboratory in Japan. "Meaning state-oriented people were just as good, and as fast at making those small choices, as were the action-oriented people. The action-oriented people were, however, much more confident." The team asked participants, who had been assessed -- through screening questionnaires -- to be either very decisive or not, to complete a number of tasks.

According to a new study, dogs were able to better detect COVID-19 than PCR antigenic tests in both symptomatic and asymptomatic people. Slashdot Falconhell shares the report via The Guardian: In the study, trained dogs were able to detect Covid in 97% of symptomatic cases and nearly 100% of asymptomatic cases. The study featured 335 participants from Covid screening centers in Paris. Of the participants, 109 were positive with Covid, including 31 who were asymptomatic. The detection dogs, provided by French fire stations and the United Arab Emirates, received three to six weeks of training, depending on if a dog was previously trained for odor detection. The dogs sniffed samples of human sweat placed in an olfaction cone. If a dog detected Covid, it sat down in front of the cone.

Ultimately, the trained dogs were more sensitive to positive cases. Nasal PCR tests were better able to better detect negative cases. In two false positive cases, dogs falsely identified other coronavirus respiratory illness strains that were not Covid. While there have been previous studies on the capability of dogs to detect Covid, this is believed to be the first to compare the accuracy of dogs to antigenic tests. The study has been published in the journal Plos One.

Amateur astronomers are preparing for a heavenly treat from Friday as the five planets visible to the naked eye line up in order of their distance from the sun across the pre-dawn sky. From a report: For those who can face the early start, and have an unobstructed view of the horizon to the east and south-east, Mercury, Venus, Mars, Jupiter and Saturn, could all be visible before the faintest, Mercury, vanishes in the glare of sunrise. It is not uncommon to see two or three planets close together, but the five that can be spotted with the naked eye have not appeared in order, as viewed from the northern hemisphere, since December 2004.

"This is really cool," said Prof Beth Biller, personal chair of exoplanet characterisation at Edinburgh University's institute for astronomy. "We now know of many other stars hosting multiple planets. This is a rare opportunity to see the same thing closer to home, with all five 'naked eye' planets in our solar system visible at once." The planets of the solar system orbit the sun in a remarkably narrow plane, meaning that when viewed from Earth, they appear to lie close to an imaginary line in the sky called the ecliptic. The five planets will rise above the horizon in the early hours of Friday, though it may be hard to see them all until later in the month.

That morning cup of coffee may be linked to a lower risk of dying, researchers from a study published Monday in The Annals of Internal Medicine concluded. From a report: Those who drank 1.5 to 3.5 cups of coffee per day, even with a teaspoon of sugar, were up to 30 percent less likely to die during the study period than those who didn't drink coffee. Those who drank unsweetened coffee were 16 to 21 percent less likely to die during the study period, with those drinking about three cups per day having the lowest risk of death when compared with noncoffee drinkers.

Researchers analyzed coffee consumption data collected from the U.K. Biobank, a large medical database with health information from people across Britain. They analyzed demographic, lifestyle and dietary information collected from more than 170,000 people between the ages of 37 and 73 over a median follow-up period of seven years. The mortality risk remained lower for people who drank both decaffeinated and caffeinated coffee. The data was inconclusive for those who drank coffee with artificial sweeteners. "It's huge. There are very few things that reduce your mortality by 30 percent," said Dr. Christina Wee, an associate professor of medicine at Harvard Medical School and a deputy editor of the scientific journal where the study was published. Dr. Wee edited the study and published a corresponding editorial in the same journal.

New spacesuits made by Axiom Space and Collins Aerospace could be worn by astronauts that land on the moon later this decade through NASA's Artemis program, the agency announced Wednesday. The suits will also be worn by crew members living and working on the International Space Station. CNN reports: The contracts were awarded by NASA as part of its strategy of growing commercial partnerships. Both companies have been selected to move forward in developing the next generation of spacesuits. Depending on how the two companies deliver on the suits and their spacewalking capabilities, one company could prevail over the other. That flexibility has been built into the task awards as the two companies progress in product development.

The Artemis program seeks to land the first woman and the first person of color at the lunar south pole by 2025, and eventually prepare for landing crewed missions on Mars. Experts from NASA have developed the required safety and technical standards for the spacesuits. Axiom Space and Collins Aerospace will design, develop and potentially produce the suits and any necessary equipment for space station crew and Artemis astronauts. [...] The suits are expected to be ready by the mid-2020s.

The "use-by" and "best-by" dates printed on milk cartons and gallon jugs may soon become a thing of the past, giving way to more accurate and informative QR codes. Phys.Org reports: A new Cornell University study finds that consumers will use the QR codes to better depict how long the milk is drinkable and create substantially less agricultural and food waste. In the U.S., dairy products are among the top three food groups with the largest share of wasted food, said Samantha Lau, a doctoral student in food science who works in the lab of Martin Wiedmann, the professor of food safety in the College of Agriculture and Life Sciences.

In the early spring semester, Lau, also working with Cornell's Milk Quality Improvement Program, connected with the Cornell Dairy Bar, which sells fluid milk in addition to ice cream on campus. She wanted to assess consumer acceptance for QR code technology that may one day replace the static best-by or sell-by dates commonly found on food products. Customers had a choice: purchasing milk with printed best-by dates, or buying containers with QR codes, which when scanned by a smart phone, would display the best-by date.

In the same Cornell Dairy Bar study, Lau placed a dynamic pricing element where consumers were encouraged to purchase milk with a shorter remaining shelf life -- by offering a price discount as the best-by date approached. "During two-month study, over 60% of customers purchased the milk with the QR code, showing a considerable interest in using this new technology," Lau said. "This revealed that the use of QR codes on food products can be an innovative way to address the larger issue of food waste." Wiedmann says the technology also exists where smart milk cartons could communicate with smart refrigerators to inform a household of the need for fresh milk.

The study has been published in the Journal of Dairy Science.
