"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.

In Shark Bay, off the westernmost tip of Australia, meadows of sea grass carpet the ocean floor, undulating in the current and being nibbled on by dugongs, cousins of Florida manatees. A new study revealed something unexpected about those sea grasses: Many of them are the same individual plant that has been cloning itself for about 4,500 years. From a report: The sea grass -- not to be confused with seaweed, which is an algae -- is Poseidon's ribbon weed, or Posidonia australis. Jane Edgeloe, a University of Western Australia Ph.D. candidate and an author of the paper, likens its appearance to a spring onion. Ms. Edgeloe and her colleagues made their discovery as part of a genetic survey of Posidonia grasses in different areas of Shark Bay, where she SCUBA dived in the shallow waters and pulled up shoots of Posidonia from 10 different meadows. On land, the researchers analyzed and compared the grasses' DNA.

They published their results Wednesday in the journal Proceedings of the Royal Society B. It turned out the DNA of many of those seemingly different plants was virtually identical. Elizabeth Sinclair, also of the University of Western Australia and an author of the study, recalled excitement in the lab when she realized: "It's only one plant."While some of Shark Bay's northern meadows reproduce sexually, the rest of its Posidonia clones itself by creating new shoots that branch off from its root system. Even separate meadows were genetically identical, indicating that they were once connected by now-severed roots. Based on how old the bay is and how quickly sea grasses grow, the researchers surmise that the Shark Bay clone is about 4,500 years old.

sciencehabit shares a report from Science Magazine: Big Brother is listening. Companies use "bossware" to listen to their employees when they're near their computers. Multiple "spyware" apps can record phone calls. And home devices such as Amazon's Echo can record everyday conversations. A new technology, called Neural Voice Camouflage, now offers a defense. It generates custom audio noise in the background as you talk, confusing the artificial intelligence (AI) that transcribes our recorded voices.

The new system uses an "adversarial attack." The strategy employs machine learning -- in which algorithms find patterns in data -- to tweak sounds in a way that causes an AI, but not people, to mistake it for something else. Essentially, you use one AI to fool another. The process isn't as easy as it sounds, however. The machine-learning AI needs to process the whole sound clip before knowing how to tweak it, which doesn't work when you want to camouflage in real time.

So in the new study, researchers taught a neural network, a machine-learning system inspired by the brain, to effectively predict the future. They trained it on many hours of recorded speech so it can constantly process 2-second clips of audio and disguise what's likely to be said next. For instance, if someone has just said "enjoy the great feast," it can't predict exactly what will be said next. But by taking into account what was just said, as well as characteristics of the speaker's voice, it produces sounds that will disrupt a range of possible phrases that could follow. That includes what actually happened next; here, the same speaker saying, "that's being cooked." To human listeners, the audio camouflage sounds like background noise, and they have no trouble understanding the spoken words. But machines stumble. The work was presented in a paper last month at the International Conference on Learning Representations, which peer reviews manuscript submissions.

In early 2020, the distant supergiant star, 700 light-years away known as Betelgeuse experienced an odd uneven dimming, leaving the astronomy community scrambling to explain what happened. In a new study recently published in the journal Nature, a trio of astronomers managed to confirm some of the earlier explanations thanks to a Japanese weather satellite, Himawari-8, which had Betelgeuse lurking in the background of its images. CNET reports: Himawari-8 is, as the name suggests, the eighth version of the Himawari satellite operated by Japan's Meteorological Agency. It operates in geostationary orbit, at a distance of 22,236 miles above the equator. This is more than 90 times further away than the International Space Station. From that position, the satellite snaps optical and infrared images of the whole Earth once every 10 minutes, predominantly to help forecast the weather across Asia and the Western Pacific. For instance, it snapped a ton of images of the Tongan volcano eruption that occurred on Jan. 15. However, looking through images stretching back to 2017, the trio of Japanese researchers went looking for a pinprick of light that would be Betelgeuse, lurking in space behind our brilliant blue and green marble. They found it.

Studying that pinprick of light, the researchers came to the same conclusion as their predecessors: Betelgeuse dimmed because of both dust and some natural variability in its light. That's not all that exciting, but it's good confirmation we're all on the right track, and it's exactly what the process of science is all about. What is intriguing is the fact a weather satellite was able to provide this data in the first place. It could be a big deal for astronomers. Building and launching new space telescopes isn't a cheap or easy endeavor and you have to book yourself a rocket. But... there are already satellites orbiting the Earth that might be able to do a similar job.

The world produces more food than ever, but the amount of land we use is now falling. From a report: Agricultural land is the total of arable land that is used to grow crops, and pasture used to raise livestock. Measuring exactly how much land we use for agriculture is difficult. If all farms were simply rows of densely-planted crops it would be straightforward to calculate how much land is being used. Just draw a square around the field and calculate its area. But across much of the world, this is not how farming looks: it's often low-density; mixed in with rural villages; in tiny smallholdings that are somewhere between a garden and a farm. Where farmland starts and ends is not always clear-cut. As a result, there are a range of estimates for how much land is used for agriculture.

Here I have brought together the three leading analyses on the change in global land use. Each uses a different methodology, as explained in the chart (in the linked post). The UN FAO produces the bedrock data for each of these analyses from 1961 onwards; however, the researchers apply their own methodologies on top, and extend this series further back in time. As you can see, they disagree on how much land is used for agriculture, and the time at which land use peaked. But they do all agree that we have passed the peak. This marks a historic moment in humanity's relationship to the planet; a crucial step in its protection of the world's ecosystems. It shows that the future of food production does not need to follow the destructive path that it did in the past. If we continue on this path we will be able to restore space for the planet's wilderness and wildlife.

Judith Enck, a former EPA regional administrator, the president of Beyond Plastics, and a visiting professor at Bennington College, and Jan Dell, a chemical engineer and the founder of the Last Beach Cleanup, write in a piece: Americans support recycling. We do too. But although some materials can be effectively recycled and safely made from recycled content, plastics cannot. Plastic recycling does not work and will never work. The United States in 2021 had a dismal recycling rate of about 5 percent for post-consumer plastic waste, down from a high of 9.5 percent in 2014, when the U.S. exported millions of tons of plastic waste to China and counted it as recycled -- even though much of it wasn't. Recycling in general can be an effective way to reclaim natural material resources. The U.S.'s high recycling rate of paper, 68 percent, proves this point. The problem with recycling plastic lies not with the concept or process but with the material itself. The first problem is that there are thousands of different plastics, each with its own composition and characteristics. They all include different chemical additives and colorants that cannot be recycled together, making it impossible to sort the trillions of pieces of plastics into separate types for processing.

For example, polyethylene terephthalate (PET#1) bottles cannot be recycled with PET#1 clamshells, which are a different PET#1 material, and green PET#1 bottles cannot be recycled with clear PET#1 bottles (which is why South Korea has outlawed colored PET#1 bottles.) High-density polyethylene (HDPE#2), polyvinyl chloride (PVC#3), low-density polyethylene (LDPE#4), polypropylene (PP#5), and polystyrene (PS#6) all must be separated for recycling. Just one fast-food meal can involve many different types of single-use plastic, including PET#1, HDPE#2, LDPE#4, PP#5, and PS#6 cups, lids, clamshells, trays, bags, and cutlery, which cannot be recycled together. This is one of several reasons why plastic fast-food service items cannot be legitimately claimed as recyclable in the U.S. Another problem is that the reprocessing of plastic waste -- when possible at all -- is wasteful. Plastic is flammable, and the risk of fires at plastic-recycling facilities affects neighboring communities -- many of which are located in low-income communities or communities of color. Unlike metal and glass, plastics are not inert. Plastic products can include toxic additives and absorb chemicals, and are generally collected in curbside bins filled with possibly dangerous materials such as plastic pesticide containers. According to a report published by the Canadian government, toxicity risks in recycled plastic prohibit "the vast majority of plastic products and packaging produced" from being recycled into food-grade packaging.

Nearly a third of Hawaii's single-family houses have rooftop solar panels -- more than twice the percentage in California -- and officials expect many more homes to add panels and batteries in the coming years. From a report: Even before energy prices surged globally this year, homeowners, elected leaders and energy executives in Hawaii had decided that rooftop solar panels were one of the best ways to meet demand for energy and tame the state's high power costs. Russia's invasion of Ukraine has only strengthened the state's embrace of renewable energy. Electricity rates in Hawaii jumped 34 percent in April from a year earlier because many of its power plants burn oil, about a third of which came from Russia last year.

While Hawaii faces unique challenges, the state's reliance on solar carries lessons for other states and countries looking to fight climate change and bring down energy costs. The state has increased the use of renewable energy in large part by getting electric utilities to accept rooftop solar rather than fight it, as energy companies in California, Florida and other states have been doing. "In Hawaii, we've come to the recognition that rooftop solar is going to be an important part of our grid, has to be part of our grid," said Shelee Kimura, president and chief executive of Hawaiian Electric Company, the state's largest power provider. "Some people think we're crazy. Some people think we're pretty amazing."

Alarmed by the declining stature of its universities, Japan is planning to shower up to $2.3 billion a year on a handful of schools in hopes of boosting their prominence. From a report: The scheme was approved by the Japanese legislature on 18 May, although many details, including how to pick the favored universities, are still up in the air. But the move, under study for more than a year, has rekindled a debate among academics over how to reverse Japan's sinking research fortunes. Several previous schemes have yielded mixed results.

The new plan "aims to provide young promising scholars with the research environment that the world's top universities are supposed to offer, to dramatically enhance international collaborations, and to promote the brain circulation both domestically and internationally," says Takahiro Ueyama, a science policy specialist on the Council for Science, Technology and Innovation (CSTI), Japan's highest science advisory body, which was heavily involved in crafting the scheme. But Guojun Sheng, a Chinese developmental biologist at Kumamoto University in Japan, is skeptical. "I am not very optimistic that this [plan] will do much to curb the slide in the ranking of Japanese research activities or international competitiveness," he says. Sheng, who previously studied and worked in China, the United States, and the United Kingdom, says the new plan does not address fundamental problems at Japanese research institutes: too few women and foreign scientists, a fear of change, and lack of support for young scientists. To get better results, "Japan has to change its research culture," he says.

An anonymous reader shares a report: Back in March of 2017, this strange note first appeared at the end of a paper in the journal Nature: "Publisher's note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations." I looked over the paper, and it didn't have any maps in it. None of the authors had unusual affiliations, just the normal university departments. Why the disclaimer? Before answering this question, let's dig a bit deeper. This notice first started appearing in mid-March of 2017, when it was attached to every single research paper in that issue. I cannot find any papers prior to that with the "Publisher's note." Ever since then, Nature has put this notice on every paper in all of their journals. For example, the current issue has a paper on mapping sound on the planet Mars, by an international team of astronomers and physicists. It does contain maps, but they don't describe any features on Earth. Nonetheless, it has the disclaimer at the end about "jurisdictional claims in published maps."

(Nature has done it to me too, for example in this 2018 paper led by a former Ph.D. student of mine. I didn't yet know about the weird disclaimer when that paper appeared, and I didn't catch it until later.) It's not just Nature, but apparently all of the many journals published by the Nature Publishing Group, which today number in excess of 100 publications. I looked at a few randomly chosen papers in Nature Biotechnology and Cancer Gene Therapy, as a test, and they all have exactly the same Publisher's Note. None of these papers, I should add, have any maps in them. I couldn't find anything odd about the institutional affiliations either. Nature is one of the oldest and most-respected journals in all of science, dating back to 1869. Just a few years ago, in 2015, Nature's publishing group merged with Springer, the second-largest for-profit scientific publisher in the world, and they changed their name to Springer Nature. We'll see why this is relevant in a minute.
