"In a significant advancement for space technology, a team of UC Berkeley researchers, led by doctoral student Taylor Waddell, successfully launched a 3D printer into space," reports the university's student newspaper: As part of the Virgin Galactic 07 mission, the team sent a 3D printer named SpaceCAL to space to explore the potential of Computed Axial Lithography, or CAL, and additive manufacturing in space... During its 140-second flight in suborbital space, the SpaceCAL printer autonomously detected microgravity and printed four test parts: two space shuttles and two Benchies, or 3D-printed boats created to check the printer's accuracy, according to Sean Chu, a member of the team who worked on designing structures and mechanisms. Within the 140 seconds, the process involved multiple steps such as printing, post-washing, flushing with water and post-curing with light to fully solidify the parts.
But that's just the beginning, says the university's engineering department: To date, CAL has shown that it can successfully print with more than 60 different materials on Earth, such as silicones, glass composites and biomaterials. According to Waddell, this versatility could come in handy for both the cabin and the crew... "CAL is also capable of repairing the crew. We can print dental replacements, skin grafts or lenses, or things personalized in emergency medicine for astronauts, which is very important in these missions, too."

Someday, CAL may be used to print even more sophisticated parts, such as human organs. Lawrence Livermore National Lab has received a grant from NASA to test this technology on the International Space Station. "They're going to basically do bioprinting on the Space Station," said Waddell. "And the long, long-term goal is to print organs up in space with CAL, then bring them back down to Earth." Next, Waddell and his colleagues hope to begin work with NASA on developing and validating a single object that could support crew health and wellness, like a dental crown for an astronaut or a surgical wound closure tool...

This project was made possible through a $1.4 million grant and engineering support provided by NASA. In addition, Virgin Galactic played a pivotal role in taking this project to the next level.

An anonymous reader shared this report from ScienceAlert: NASA's Parker Solar Probe, tasked with taking a close-up look at the Sun's outer corona, has just equalled the record for the fastest-moving human-made object ever. The previous record holder? The Parker Solar Probe, again. The probe was recorded traveling at 635,266 kilometers (394,736 miles) per hour on June 29, the second time it's reached that speed since it launched in 2018. We're talking around 500 times faster than the speed of sound here. It's on course to get even faster too, with a top speed of around 692,000 kph (430,000 mph) expected when it makes its closest approach to the Sun in 2025.
It's the probe's 20th approach to the sun, according to the article, with the probe using Venus "to create a sort of gravity-powered slingshot," according to the article. (NASA has created a nice interactive 3D model of the probe...)

Besides collecting particle samples in 2021, "The probe is eventually going to get nice and close to the swirling mass of ultra-hot plasma surrounding the Sun, and take a wealth of different measurements to help improve our scientific understanding of it."

clovis (Slashdot reader #4,684) writes: Joe Engle received his astronaut wings in a ceremony on July 15, 1965, for his flight in the hypersonic aircraft, reaching an altitude of 50 miles above the Earth. At 32, he was the youngest man to become an astronaut.

Later, he entered the Apollo program and eventually commanded the STS-2 flight of the Space Shuttle.

Here is an interview from 2004. I thought it was interesting that they used the F-104 as the chase plane and for training because the flight characteristics were so similar, which says a lot about the F-104.

Anyway, the X-15 project was a big deal for us science/geek types back when I was a kid. I wonder if it's something today's generation is even aware of.

An anonymous reader quotes a report from DefenseScoop: A group of NATO countries are set to begin implementing a new project aimed at improving the alliance's ability to quickly share intelligence gathered by space-based assets operated by both member nations and the commercial sector. Seventeen NATO members signed a memorandum of understanding for the Alliance Persistence Surveillance from Space (APSS) program as part of the annual NATO summit being held in Washington this week, the alliance announced Tuesday. Members will now move into a five-year implementation phase of the project, during which allies will contribute more than $1 billion "to leverage commercial and national space assets, and to expand advanced exploitation capacities," according to a press release.

The United States is one of the nations signed onto the initiative, as well as Belgium, Canada, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Luxembourg, the Netherlands, Norway, Poland, Romania, Sweden and Turkey, according to a NATO source. The transatlantic organization created APSS last year with the intent to establish a "virtual constellation" -- dubbed Aquila -- comprising both national and commercial space systems, sensors and data that can be used by NATO's command structure and other allies. The project is considered "the largest multinational investment in space-based capabilities" in the alliance's history, and is set to increase NATO's ability "to monitor activities on the ground and at sea with unprecedented accuracy and timeliness," a press release stated.

Participating nations will be able to use their own space systems, provide tools for intelligence collection and analysis, or purchase space-based data gathered by commercial constellations. "Integrating and exploiting data from space effectively has been a growing challenge over time," a NATO press release stated. "By leveraging latest technologies from industry, APSS will help advance NATO's innovation agenda and offer a new platform to engage with the growing space industry." The APSS project is part of the larger implementation of NATO's overarching space policy adopted in 2019, which officially recognized space as a new operational domain. Since then, the alliance has worked to bolster its presence in space -- including the establishment of a NATO Space Centre in 2020 and approval of an official Space Branch within the Allied Command Transformation in June.

Researchers from Cornell University have developed a novel urine collection and filtration system for spacesuits, designed to improve hygiene and comfort for astronauts during long spacewalks. This new system, inspired by the 'stillsuits' from the Dune franchise, recycles urine into potable water using a vacuum-based external catheter and a forward-reverse osmosis unit. It's expected to be tested for use in upcoming NASA moon and Mars missions. Phys.Org reports: [Researchers] have now designed a urine collection device, including an undergarment made of multiple layers of flexible fabric. This connects to a collection cup (with a different shape and size for women and men) of molded silicone, to fit around the genitalia. The inner face of the collection cup is lined with polyester microfiber or a nylon-spandex blend, to draw urine away from the body and towards the inner cup's inner face, from where it is sucked by a vacuum pump. A RFID tag, linked to an absorbent hydrogel, reacts to moisture by activating the pump.

Once collected, the urine is diverted to the urine filtration system, where it gets recycled with an efficiency of 87% through a two-step, integrated forward and reverse osmosis filtration system. This uses a concentration gradient to remove water from urine, plus a pump to separate water from salt. The purified water is then enriched in electrolytes and pumped into the in-suit drink bag, again available for consumption. Collecting and purifying 500ml of urine takes only five minutes.

The system, which integrates control pumps, sensors, and a liquid-crystal display screen, is powered by a 20.5V battery with a capacity of 40 amp-hours. Its total size is 38 by 23 by 23 cm, with a weight of approximately eight kilograms: sufficiently compact and light to be carried on the back of a spacesuit. Now that the prototype is available, the new design can be tested under simulated conditions, and subsequently during real spacewalks. The design has been published in the journal Frontiers in Space Technology.

An anonymous reader quotes a report from Reuters: SpaceX's workhorse Falcon 9 rocket was grounded by the U.S. Federal Aviation Administration (FAA) on Friday after one broke apart in space and doomed its payload of Starlink satellites, the first failure in more than seven years of a rocket relied upon by the global space industry. Roughly an hour after Falcon 9 lifted off from the Vandenberg Space Force Base in California on Thursday night, the rocket's second stage failed to reignite and deployed its 20 Starlink satellites on a shallow orbital path where they will soon reenter and burn up in Earth's atmosphere.

The attempt to reignite the engine "resulted in an engine RUD for reasons currently unknown," SpaceX CEO Elon Musk wrote early on Friday on his social media platform X, using an industry acronym for Rapid Unscheduled Disassembly that usually means explosion. The Falcon 9 will be grounded until SpaceX investigates the cause of the failure, fixes the rocket and receives the agency's approval, the FAA said in a statement. That process could take several weeks or months, depending on the complexity of the failure and SpaceX's plan to fix it. Musk said SpaceX was updating the software of the Starlink satellites to force their on-board thrusters to fire harder than usual to avoid a fiery atmospheric re-entry. "Unlike a Star Trek episode, this will probably not work, but it's worth a shot," Musk said.

The satellites' altitude is so shallow that Earth's gravity is pulling them 3 miles (5 km) closer toward the atmosphere with each orbit, SpaceX later said, confirming they would inevitably "re-enter Earth's atmosphere and fully demise." SpaceX said the second stage's failure occurred after engineers detected a leak of liquid oxygen, a propellant. The mishap occurred on Falcon 9's 354th mission. It was the first Falcon 9 failure since 2016, when a rocket exploded on a launch pad in Florida and destroyed its customer payload, an Israeli communications satellite. The failure "breaks a success streak of more than 300 straight missions," notes Reuters.

"We knew this incredible run had to come to an end at some point," Tom Mueller, SpaceX's former vice president of propulsion who designed Falcon 9's engines. "... The team will fix the problem and start the cycle again."

Scientists say "a reservoir of disease" is being created after discovering bacteria that naturally occur in rivers are becoming resistant to antibiotics due to the impact of sewage. From a report: Researchers at the University of Suffolk said bacterial strains found on the non-tidal section of the River Deben in Suffolk had acquired resistance by exchanging DNA with antibiotic resistant E. coli. Some bacteria have become resistant to the antibiotic carbapenem, which is used as the last line of defence in fighting infections already resistant to traditional antibiotics. Dr Nick Tucker, a microbiologist leading the research, described the discovery as "particularly worrying."

"Organisms that are currently low risk are being mixed with pathogenic organisms from sewage," he said. "We're needlessly adding pathogenic and virulence genes to bacteria found in the environment, and that could be creating a reservoir of disease." The team has been working closely with citizen scientists from the Deben Climate Centre, who have been taking water samples for two years. They have also been working with scientists at the government's CEFAS laboratories, who have helped identify the new strains that are being screened for their resistance to six of the most commonly-used antibiotics. The River Deben rises in Debenham, Suffolk, before flowing through Woodbridge and down to the North Sea.

The Conversation: Reading and writing articles published in academic journals and presented at conferences is a central part of being a researcher. When researchers write a scholarly article, they must cite the work of peers to provide context, detail sources of inspiration and explain differences in approaches and results. A positive citation by other researchers is a key measure of visibility for a researcher's own work. But what happens when this citation system is manipulated? A recent Journal of the Association for Information Science and Technology article by our team of academic sleuths -- which includes information scientists, a computer scientist and a mathematician -- has revealed an insidious method to artificially inflate citation counts through metadata manipulations: sneaked references.

People are becoming more aware of scientific publications and how they work, including their potential flaws. Just last year more than 10,000 scientific articles were retracted. The issues around citation gaming and the harm it causes the scientific community, including damaging its credibility, are well documented. Citations of scientific work abide by a standardized referencing system: Each reference explicitly mentions at least the title, authors' names, publication year, journal or conference name, and page numbers of the cited publication. These details are stored as metadata, not visible in the article's text directly, but assigned to a digital object identifier, or DOI -- a unique identifier for each scientific publication.

References in a scientific publication allow authors to justify methodological choices or present the results of past studies, highlighting the iterative and collaborative nature of science. However, we found through a chance encounter that some unscrupulous actors have added extra references, invisible in the text but present in the articles' metadata, when they submitted the articles to scientific databases. The result? Citation counts for certain researchers or journals have skyrocketed, even though these references were not cited by the authors in their articles.

A group of astronomers want to change the definition of a planet. Their new proposed definition wouldn't bring Pluto back into the planetary fold, but it could reclassify thousands of celestial bodies across the universe. From a report: The International Astronomical Union's (IAU) current definition of a planet, established in 2006, includes only celestial bodies that are nearly round, are gravitationally dominant and orbit our Sun. This Sun-centric definition excludes all of the bodies we've discovered outside our solar system, even if they may fit all other parameters. They are instead considered exoplanets. Those behind the new proposal critiqued the IAU's definition in an upcoming paper in the Planetary Science Journal, arguing it's vague, not quantitative and unnecessarily exclusionary.

Their new proposal would instead classify planets based on their mass, considering a planet to be any celestial body that:
1. orbits one or more stars, brown dwarfs or stellar remnants and,
is more massive than 10ÂÂ kilograms (kg) and,
is less massive than 13 Jupiter masses (2.5 X 10^28Âkg).

Aryan Kapoor, a high schooler from JRD Propulsion, successfully developed a model rocket with SpaceX-style vertical landing capabilities. The three-year effort was made possible by a thrust-vector control and clever landing gear design. Hackaday reports: He started in 2021 with none of the basic skills needed to pull off something like this, but it seems like he quickly learned the ropes. His development program was comprehensive, with static test vehicles, a low-altitude hopper, and extensive testing of the key technology: thrust-vector control. His rocket uses two solid-propellant motors stacked on top of each other, one for ascent and one for descent and landing. They both live in a 3D printed gimbal mount with two servos that give the stack plus and minus seven degrees of thrust vectoring in two dimensions, which is controlled by a custom flight computer with a barometric altimeter and an inertial measurement unit. The landing gear is also clever, using rubber bands to absorb landing forces and syringes as dampers. You can watch the first successful test flight and landing on YouTube.

The idea that night owls who don't go to bed until the early hours struggle to get anything done during the day may have to be revised. From a report: It turns out that staying up late could be good for our brain power as research suggests that people who identify as night owls could be sharper than those who go to bed early. Researchers led by academics at Imperial College London studied data from the UK Biobank study on more than 26,000 people who had completed intelligence, reasoning, reaction time and memory tests.

They then examined how participants' sleep duration, quality, and chronotype (which determines what time of day we feel most alert and productive) affected brain performance. They found that those who stay up late and those classed as "intermediate" had "superior cognitive function," while morning larks had the lowest scores. Going to bed late is strongly associated with creative types.

A recent study has exposed a method of artificially inflating citation counts through "sneaked references," which are extra citations included in metadata but not in the actual text of articles. This manipulation, uncovered in journals by Technoscience Academy, distorts citation metrics that are critical for research funding and academic promotions. The Conversation reports: The investigation began when Guillaume Cabanac, a professor at the University of Toulouse, wrote a post on PubPeer, a website dedicated to post-publication peer review, in which scientists discuss and analyze publications. In the post, he detailed how he had noticed an inconsistency: a Hindawi journal article that he suspected was fraudulent because it contained awkward phrases had far more citations than downloads, which is very unusual. The post caught the attention of several sleuths who are now the authors of the JASIST article. We used a scientific search engine to look for articles citing the initial article. Google Scholar found none, but Crossref and Dimensions did find references. The difference? Google Scholar is likely to mostly rely on the article's main text to extract the references appearing in the bibliography section, whereas Crossref and Dimensions use metadata provided by publishers.

To understand the extent of the manipulation, we examined three scientific journals that were published by the Technoscience Academy, the publisher responsible for the articles that contained questionable citations. [...] In the journals published by Technoscience Academy, at least 9% of recorded references were "sneaked references." These additional references were only in the metadata, distorting citation counts and giving certain authors an unfair advantage. Some legitimate references were also lost, meaning they were not present in the metadata. In addition, when analyzing the sneaked references, we found that they highly benefited some researchers. For example, a single researcher who was associated with Technoscience Academy benefited from more than 3,000 additional illegitimate citations. Some journals from the same publisher benefited from a couple hundred additional sneaked citations.

We wanted our results to be externally validated, so we posted our study as a preprint, informed both Crossref and Dimensions of our findings and gave them a link to the preprinted investigation. Dimensions acknowledged the illegitimate citations and confirmed that their database reflects Crossref's data. Crossref also confirmed the extra references in Retraction Watch and highlighted that this was the first time that it had been notified of such a problem in its database. The publisher, based on Crossref's investigation, has taken action to fix the problem. To combat this practice of "sneaked references," the authors suggest several measures: rigorous verification of metadata by publishers and agencies like Crossref, independent audits to ensure data reliability, and increased transparency in managing references and citations.

Longtime Slashdot reader ArchieBunker shares a report from TIME Magazine: On an evening in December 2023, 43-year-old small business owner Sarah Rosenkranz collapsed in her home in Granbury, Texas and was rushed to the emergency room. Her heart pounded 200 beats per minute; her blood pressure spiked into hypertensive crisis; her skull throbbed. "It felt like my head was in a pressure vise being crushed," she says. "That pain was worse than childbirth." Rosenkranz's migraine lasted for five days. Doctors gave her several rounds of IV medication and painkiller shots, but nothing seemed to knock down the pain, she says. This was odd, especially because local doctors were similarly vexed when Indigo, Rosenkranz's 5-year-old daughter, was taken to urgent care earlier that year, screaming that she felt a "red beam behind her eardrums." It didn't occur to Sarah that these symptoms could be linked. But in January 2024, she walked into a town hall in Granbury and found a room full of people worn thin from strange, debilitating illnesses. A mother said her 8-year-old daughter was losing her hearing and fluids were leaking from her ears. Several women said they experienced fainting spells, including while driving on the highway. Others said they were wracked by debilitating vertigo and nausea, waking up in the middle of the night mid-vomit. None of them knew what, exactly, was causing these symptoms. But they all shared a singular grievance: a dull aural hum had crept into their lives, which growled or roared depending on the time of day, rattling their windows and rendering them unable to sleep. The hum, local law enforcement had learned, was emanating from a Bitcoin mining facility that had recently moved into the area -- and was exceeding legal noise ordinances on a daily basis.

Over the course of several months in 2024, TIME spoke to more than 40 people in the Granbury area who reported a medical ailment that they believe is connected to the arrival of the Bitcoin mine: hypertension, heart palpitations, chest pain, vertigo, tinnitus, migraines, panic attacks. At least 10 people went to urgent care or the emergency room with these symptoms. The development of large-scale Bitcoin mines and data centers is quite new, and most of them are housed in extremely remote places. There have been no major medical studies on the impacts of living near one. But there is an increasing body of scientific studies linking prolonged exposure to noise pollution with cardiovascular damage. And one local doctor -- ears, nose, and throat specialist Salim Bhaloo -- says he sees patients with symptoms potentially stemming from the Bitcoin mine's noise on an almost weekly basis. "I'm sure it increases their cortisol and sugar levels, so you're getting headaches, vertigo, and it snowballs from there," Bhaloo says. "This thing is definitely causing a tremendous amount of stress. Everyone is just miserable about it." "By the end of 2024, we intend to have replaced the majority of air-cooled containers with immersion cooling, with no expansion required," said a representative for Marathon Digital Holdings, the company that owns the mine. "Initial sound readings on immersion containers indicate favorable results in sound reduction and compliance with all relevant state noise ordinances." They did not answer questions about the health impacts their mining site was causing.

"We're living in a nightmare," said Rosenkranz. She clocked the hum at 72 decibels in Indigo's bedroom in the dead of night. "Indigo's room directly faces the mine, which sits about a mile and a half away," notes TIME. She had to be pulled from her school after she developed so many ear infections from the sound.

The report also said a resident's dog "started going bald and developed debilitating anxiety shortly after the Bitcoin mine began operating four blocks away." TIME added: "Directly next door, Tom Weeks' dog Jack Rabbit Slim started shaking and hyperventilating uncontrollably for hours on end; a vet placed him on the seizure medication Gabapentin. Rosenkranz's chickens stopped laying eggs for months. And Jerry and Patricia Campbell's centuries-old oak tree, which had served as the family's hub and protector for generations of backyard family reunions and even a wedding, died suddenly three months ago."

OpenAI CEO Sam Altman and businesswoman Arianna Huffington have announced they're working on an "AI health coach" via Thrive AI Health. According to a Time magazine op-ed, the two executives said that the bot will be trained on "the best peer-reviewed science" alongside "the personal biometric, lab, and other medical data you've chosen to share with it." The Verge reports: The company tapped DeCarlos Love, a former Google executive who previously worked on Fitbit and other wearables, to be CEO. Thrive AI Health also established research partnerships with several academic institutions and medical centers like Stanford Medicine, the Rockefeller Neuroscience Institute at West Virginia University, and the Alice L. Walton School of Medicine. (The Alice L. Walton Foundation is also a strategic investor in Thrive AI Health.) Thrive AI Health's goal is to provide powerful insights to those who otherwise wouldn't have access -- like a single mother looking for quick meal ideas for her gluten-free child or an immunocompromised person in need of instant advice in between doctor's appointments. [...]

The bot is still in its early stages, adopting an Atomic Habits approach. Its goal is to gently encourage small changes in five key areas of your life: sleep, nutrition, fitness, stress management, and social connection. By making minor adjustments, such as suggesting a 10-minute walk after picking up your child from school, Thrive AI Health aims to positively impact people with chronic conditions like heart disease. It doesn't claim to be ready to provide real diagnosis like a doctor would but instead aims to guide users into a healthier lifestyle. "AI is already greatly accelerating the rate of scientific progress in medicine -- offering breakthroughs in drug development, diagnoses, and increasing the rate of scientific progress around diseases like cancer," the op-ed read.

Starting this fall, most students at Johns Hopkins' medical school will attend tuition-free thanks to a $1 billion donation from billionaire Mike Bloomberg. From a report: The generous gift is intended to address "twin challenges of declining levels of health and education," Bloomberg said in a letter Monday. The donation will cover the full cost of tuition for medical students from families earning less than $300,000, Bloomberg Industries announced Monday. It will also cover living expenses and other fees for students from families earning up to $175,000.

Currently, nearly two-thirds of medical students at the school qualify for financial aid. Johns Hopkins' medical students graduate with an average student loan debt of about $104,000. The donation will also increase financial aid at some of the university's other graduate schools, including the schools of nursing and public health.

A controversial organ retrieval technique is gaining traction across the U.S., promising to alleviate chronic organ shortages but also sparking intense ethical debates, NPR reports. Normothermic regional perfusion, now used by half of the nation's organ procurement organizations, restores blood flow to organs after cardiac death. Proponents argue it increases viable organ supply and improves transplant outcomes. Critics, however, question whether the procedure blurs the definition of death.

An anonymous reader quotes a report from The Guardian: Air pollution exposure can significantly decrease the chance of a live birth after IVF treatment, according to research that deepens concern about the health impacts of toxic air on fertility. Pollutant exposure has previously been linked to increased miscarriage rates and preterm births, and microscopic soot particles have been shown to travel through the bloodstream into the ovaries and the placenta. The latest work suggests that the impact of pollution begins before conception by disrupting the development of eggs. "We observed that the odds of having a baby after a frozen embryo transfer were more than a third lower for women who were exposed to the highest levels of particulate matter air pollution prior to egg collection, compared with those exposed to the lowest levels," said Dr Sebastian Leathersich, a fertility specialist and gynaecologist from Perth who is due to present the findings on Monday at the European Society of Human Reproduction and Embryology annual meeting in Amsterdam. [...]

The study analyzed fertility treatments in Perth over an eight-year period, including 3,659 frozen embryo transfers from 1,836 patients, and tracked whether outcomes were linked to the levels of fine particulate matter, known as PM10. The overall live birthrate was about 28% per transfer. However, the success rates varied in line with exposure to pollutants in the two weeks leading up to egg collection. The odds of a live birth decreased by 38% when comparing the highest quartile of exposure to the lowest quartile. "These findings suggest that pollution negatively affects the quality of the eggs, not just the early stages of pregnancy, which is a distinction that has not been previously reported," Leathersich said. The team now plan to study cells directly to understand why pollutants have a negative effect. Previous work has shown that the microscopic particles can damage DNA and cause inflammation in tissues. The report notes that the link between air pollution and live birth "was apparent despite excellent overall air quality during the study period, with PM10 and PM2.5 levels exceeding WHO guidelines on just 0.4% and 4.5% of the study days."

It adds: "Australia is one of just seven countries that met the WHO's guidelines in 2023, and this study is the latest to show evidence of harm even at relatively low levels of pollution."

The study has been published in the journal Human Reproduction.

The world has baked for 12 consecutive months in temperatures 1.5C (2.7F) greater than their average before the fossil fuel era, new data shows. Temperatures between July 2023 and June 2024 were the highest on record, scientists found, creating a year-long stretch in which the Earth was 1.64C hotter than in preindustrial times. From a report: The findings do not mean world leaders have already failed to honour their promises to stop the planet heating 1.5C by the end of the century -- a target that is measured in decadal averages rather than single years -- but that scorching heat will have exposed more people to violent weather. A sustained rise in temperatures above this level also increases the risk of uncertain but catastrophic tipping points.

Carlo Buontempo, director of the Copernicus Climate Change Service, which analysed the data, said the results were not a statistical oddity but a "large and continuing shift" in the climate. "Even if this specific streak of extremes ends at some point, we are bound to see new records being broken as the climate continues to warm," he said. "This is inevitable unless we stop adding greenhouse gases into the atmosphere and the oceans." Copernicus, a scientific organisation that belongs to the EU's space programme, uses billions of measurements from satellites, ships, aircraft and weather stations to track key climate metrics. It found June 2024 was hotter than any other June on record and was the 12th month in a row with temperatures 1.5C greater than their average between 1850 and 1900. Because temperatures in some months had "relatively small margins" above 1.5C, the scientists said, datasets from other climate agencies may not confirm the 12-month temperature streak.

A Wall Street Journal analysis has revealed that private insurers in the government's Medicare Advantage program, including UnitedHealth Group, have made numerous questionable diagnoses leading to increased taxpayer-funded payments between 2018 and 2021.

The investigation found instances where patients were diagnosed with conditions they did not have, such as diabetic cataracts and HIV, often without their knowledge. These diagnoses resulted in higher payments from Medicare to the insurers. The Centers for Medicare and Medicaid Services said they are implementing changes to ensure "taxpayer dollars are appropriately spent." The story adds: In all, Medicare paid insurers about $50 billion for diagnoses added just by insurers in the three years ending in 2021, the Journal's analysis showed.

"Russia has finally admitted that American astronauts did, in fact, land on the moon," reports Newsweek: Head of Russian Space Corporation Roscosmos, Yuri Borisov, accepted the truth of the U.S. putting a man on the moon in an address to the State Duma, Intellinews has reported.

"As for whether the Americans were on the Moon or not, I have one fact to share," he was reported to have said. "I was personally interested in this matter. At one time, they provided us with a portion of the lunar soil that the astronauts brought back during their expedition." Previous polling revealed that just under half of Russians believe America's 1969 moon landing was a government hoax. However, Borisov said that tests performed on the samples by the Russian Academy of Scientists confirmed their authenticity.
