When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like mice, this replay still occurs — but the signals are jumbled and poorly coordinated. As a result, memory-supporting brain cells lose their stability, and the animals struggle to remember where they’ve been.

For all his bluster about voter fraud, Elon Musk has been one of the most flagrant flaunters of US election law. Now his America PAC has been slapped with a reprimand by the Georgia State Election Board for sending out pre-filled absentee ballot applications. State law prohibits anyone, other than an authorized relative, from sending […] Read more ›

Berlin-based T2 Linux developer René Rebe (long-time Slashdot reader ReneR) is announcing that their Xorg display server has now restored its XAA acceleration architecture, "bringing fixed-function hardware 2D acceleration back to many older graphics cards that upstream left in software-rendered mode." Older fixed-function GPUs now regain smooth window movement, low CPU usage, and proper 24-bit bpp framebuffer support (also restored in T2). Tested hardware includes ATi Mach-64 and Rage-128, SiS,...

A Redditor has passionately shown off their 21-year-old iBook G4 on the r/MacOS subreddit, arguing that Apple's extensive software support goes against the planned obsolescence accusations they get. In the post, OP's vintage iBook can be seen ready to download updates after connecting to the internet, even today. Read more ›

Apple’s AirTag is designed to help people keep track of personal belongings like keys, bags and luggage. But because AirTags and other Bluetooth trackers are small and discreet, concerns about unwanted tracking are understandable. Apple has spent years building safeguards into the AirTag and the Find My network to reduce the risk of misuse and to alert people if a tracker they don’t own appears to be moving with them.If...

The Stop Killing Games campaign is evolving into more than just a movement. In a YouTube video, the campaign's creator, Ross Scott, explained that organizers are planning to establish two non-governmental organizations, one for the European Union and another for the US. According to Scott, these NGOs would allow for "long-term counter lobbying" when publishers end support for certain video games. "Let me start off by saying I think we're... Read more ›

A massive review of 23 randomized trials found that statins do not cause the vast majority of side effects listed on their labels. Memory problems, depression, sleep issues, weight gain, and many other symptoms appeared just as often in people taking a placebo. Only a few side effects showed any link to statins — and even those were rare. Read more ›

A surprising breakthrough could help sodium-ion batteries rival lithium—and even turn seawater into drinking water. Scientists discovered that keeping water inside a key battery material, instead of removing it as traditionally done, dramatically boosts performance. The “wet” version stores nearly twice as much charge, charges faster, and remains stable for hundreds of cycles, placing it among the top-performing sodium battery materials ever reported.

Researchers have built a realistic human mini spinal cord in the lab and used it to simulate traumatic injury. The model reproduced key damage seen in real spinal cord injuries, including inflammation and scar formation. After treatment with fast moving “dancing molecules,” nerve fibers began growing again and scar tissue shrank. The results suggest the therapy could eventually help repair spinal cord damage.

A new human study has uncovered how the body naturally turns off inflammation. Researchers found that fat-derived molecules called epoxy-oxylipins rein in immune cells that can otherwise drive chronic disease. Using a drug to boost these molecules reduced pain faster and lowered harmful inflammatory cells. The discovery could pave the way for safer treatments for arthritis, heart disease, and other inflammation-related conditions. Read more ›

Qubits, the heart of quantum computers, can change performance in fractions of a second — but until now, scientists couldn’t see it happening. Researchers at NBI have built a real-time monitoring system that tracks these rapid fluctuations about 100 times faster than previous methods. Using fast FPGA-based control hardware, they can instantly identify when a qubit shifts from “good” to “bad.” The discovery opens a new path toward stabilizing and... Read more ›

An Ice Age double burial in Italy has yielded a stunning genetic revelation. DNA from a mother and daughter who lived over 12,000 years ago shows that the younger had a rare inherited growth disorder, confirmed through mutations in a key bone-growth gene. Her mother carried a milder version of the same mutation. The finding not only solves a long-standing mystery but also proves that rare genetic diseases stretch far... Read more ›

A massive, centuries-long drought may have driven the extinction of the “hobbits” of Flores. Climate records preserved in cave formations show rainfall plummeted just as the small human species disappeared. At the same time, pygmy elephants they depended on declined sharply as rivers dried up. With food and water vanishing, the hobbits may have been pushed out—and into their final chapter. Read more ›

Researchers investigating crops grown in soil contaminated by the 2015 mining disaster in Brazil discovered that toxic metals are moving from the earth into edible plants. Bananas, cassava, and cocoa were found to absorb elements like lead and cadmium, with bananas showing a potential health risk for children under six. Although adults face lower immediate danger, scientists warn that long-term exposure could carry cumulative health consequences. Read more ›

As the planet warms, many expected ecosystems to change faster and faster. Instead, a massive global study shows that species turnover has slowed by about one-third since the 1970s. Nature’s constant reshuffling appears to be driven more by internal ecological dynamics than by climate alone. The slowdown may signal something alarming: ecosystems losing the biodiversity needed to keep their engines running. Read more ›

Researchers have uncovered the enzyme behind chromothripsis, a chaotic chromosome-shattering event seen in about one in four cancers. The enzyme, N4BP2, breaks apart DNA trapped in tiny cellular structures, unleashing a burst of genetic changes that can help tumors rapidly adapt and resist therapy. Blocking the enzyme dramatically reduced this genomic destruction in cancer cells. Read more ›
