NIH CENTRALIZES RESEARCH PROPOSAL REVIEWS AMID MIXED REACTIONS
The National Institutes of Health (NIH) is centralizing its research proposal review process, with the Center for Scientific Review (CSR) set to handle all reviews starting later this year. Currently, CSR reviews 78% of the 66,000 annual grant submissions, while separate NIH institutes manage the rest. The new plan eliminates institute-run panels, which will result in job losses for some staff, though many will transition to CSR. NIH claims the changes will streamline operations, saving $65 million annually, and address concerns about potential biases in the review process. However, the shift has sparked mixed reactions. Some see the consolidation as an efficiency boost, while others fear it may disrupt specialized reviews and affect the quality of evaluations. There is also concern about a backlog of 16,000 proposals, which CSR aims to address in the coming weeks, though it remains unclear when institute panel meetings will resume. (Science)
PHYSICIST CHALLENGES MICROSOFT CLAIM ON TOPLOGICAL QUBITS
A physicist has raised doubts about Microsoft’s claim of creating the first “topological qubits,” a milestone in quantum computing. The company announced the breakthrough on February 19, 2024, but critics point to the lack of peer-reviewed evidence and the flaws in the test used to identify Majoranas, the elusive quasiparticles needed for topological qubits. The test, called the topological gap protocol (TGP), has been criticized for false positives and inconsistencies due to varying conditions during measurements. While Microsoft stands by its claims, asserting that the protocol is valid, physicists like Henry Legg argue that the TGP may not reliably identify Majoranas. Further concerns include discrepancies in the protocol’s implementation and the lack of transparency regarding key data. Microsoft has yet to release all details of its research, citing intellectual-property concerns, and more information may emerge during an upcoming talk by Microsoft’s Chetan Nayak. However, skepticism persists in the scientific community. (Nature)
GENETICALLY ENGINEERED PIGS OFFER PROMISE FOR ORGAN TRANSPLANTATION
In rural Wisconsin, genetically engineered miniature pigs are being raised for a groundbreaking experiment in xenotransplantation, where animal organs are transplanted into humans. These pigs, pampered and genetically modified to have organs compatible with human bodies, are part of a larger effort to address the organ shortage crisis. With over 100,000 Americans on organ waiting lists, these pigs are genetically edited to produce organs like kidneys, hearts, and livers that may one day be used for transplantation. Recent trials have shown success, with pig kidneys functioning in human recipients, and some patients even returning to normal life. However, xenotransplantation raises ethical concerns, including the risk of cross-species disease transmission and the fairness of organ distribution. Despite the risks, many patients with organ failure are hopeful, seeing the genetically modified pigs as a lifeline. The process is still in early stages but offers promise for the future of organ transplantation. (New York Times)
NEW TREATMENT OFFERS PROMISE FOR PEOPLE WITH HYPERTENSION
A new treatment for dangerously high blood pressure could help half a million people in the UK, particularly those with primary aldosteronism, a condition that causes hypertension. This condition results from nodules on the adrenal glands that produce excess aldosterone, causing salt retention and high blood pressure. The breakthrough treatment, called targeted thermal therapy (TTT), uses intense heat from a needle to destroy these nodules, offering a non-surgical solution. The procedure takes just 20 minutes under sedation and allows patients to go home the same day. A recent trial of 28 patients showed promising results, with many patients able to stop taking medications or significantly reduce their dosage, while some saw their blood pressure return to normal. This minimally invasive procedure could replace surgery and improve the lives of people with this form of high blood pressure, reducing their risk of stroke and heart attack. (The Guardian)
CONTROVERSY SURROUNDS NASA ASTRONAUTS’ RETURN FROM SPACE STATION
A controversy has erupted regarding the return of NASA astronauts Butch Wilmore and Suni Williams from the International Space Station, after they were initially scheduled to return aboard Boeing’s malfunctioning Starliner spacecraft. President Donald Trump and SpaceX’s Elon Musk claimed their return was delayed by political reasons, accusing the Biden administration of hindering their mission. Musk also suggested that Trump pushed to accelerate their return. However, NASA officials clarified that their return was delayed due to technical and logistical reasons, such as spacecraft issues and the need for adequate preparation, not politics. They stated that discussions about their return began long before the political statements were made, and the decision to swap capsules for the Crew 10 mission was based on technical considerations. While SpaceX had offered to help with the return, NASA’s decision was driven by programmatic needs. Ultimately, Wilmore and Williams are expected to return on the Crew 9 mission in March.

SLEEPMAXXING TREND PROMOTES SLEEP OPTIMIZATION PRACTICES ONLINE
“Sleepmaxxing” is a trend focused on optimizing sleep through various practices, including supplements, food choices, and devices. This movement has gained popularity on TikTok, with videos tagged #sleepmaxxing garnering hundreds of thousands of views. While some of its tips, like sleeping in a cool, dark room, limiting screen time before bed, and maintaining a consistent sleep schedule, are evidence-based and proven to improve sleep quality, others are more questionable. Practices like using sleep tracking apps, red light exposure, or taking supplements like melatonin and magnesium may have mixed results. Some sleepmaxxers even turn to more extreme methods like mouth taping, which can be dangerous, or nostril expanders. While some hacks, like weighted blankets, can provide comfort, the obsession with optimizing sleep may lead to stress and worsen sleep quality, turning it into a “high-pressure chore.” Experts advise seeking professional help for ongoing sleep issues rather than relying on DIY methods.

RESEARCHERS ESTIMATE EXTINCT MEGALODON SHARK GREW UP TO 80 FEET
Researchers have reexamined the size of the extinct Otodus megalodon, the prehistoric shark that lived 15 million years ago. An international team of biologists and paleontologists used fossilized remains and compared them to modern shark species to estimate the megalodon’s size. Their study suggests the shark could have grown up to 80 feet (24 meters) long and weighed 94 tons. This estimate was based on a 36-foot-long fossilized vertebral column and comparisons with 145 living and 20 extinct shark species. The team also theorized that the megalodon was more hydrodynamic and slimmer than the bulky great white shark. The study provides insights into why some sharks achieved gigantism, while others did not. Additionally, it suggests the great white shark may have contributed to the megalodon’s extinction around 5 million years ago. However, the study’s conclusions remain tentative due to the incomplete fossil record. (Gizmodo)
