Scientists have identified a molecular switch that may help explain why aging makes the brain more vulnerable to diseases such as ALS and Huntington’s。 In worms, the protein EPS8 builds up with age and triggers signaling that encourages toxic proteins to clump together, damaging neurons and shortening lifespan。 Reducing EPS8 activity prevented thes
I wrote libcorrect in C in 2016 and wanted to revisit it in Rust。 Instead of doing just a direct conversion, I went down the rabbit hole of making Rust's std::simd work for me。 I ended up with a templated, generic Viterbi decoder for convolutional codes that dispatches the decode at runtime depending on which instruction sets are available
Taiwan’s steep, remote mountains have sheltered extraordinary forests containing hundreds of giant Taiwania firs。 After years of difficult expeditions, LiDAR mapping, and citizen-science detective work, researchers discovered an 84。1-meter (276-foot) tree, the tallest known in East Asia
Thawing Arctic permafrost is releasing ancient carbon into the ocean, raising fears that microbes could turn it into greenhouse gases and accelerate climate change。 But sediment cores collected near Canada’s Herschel Island reveal a more reassuring twist: most of this land-based carbon becomes buried in the seafloor, while only about 10 percent is
DNA traces in the Shroud of Turin reveal a remarkable mixture of human lineages, microbes, plants, animals, and coral accumulated through centuries of handling and travel。 The findings do not prove its age or authenticity, but they expose a hidden biological history preserved in the famous cloth
The solar wind may be stripping away Mars’ atmosphere by creating giant rolling waves along its outer edge。 Data from MAVEN and Tianwen-1 show that these waves form plasma clouds that carry atmospheric particles into space。 The process is concentrated on one side of Mars and may have played a major role in drying out the once potentially habitable
Animal bones preserved in South Australia’s underwater caves reveal distinctive clues shaped by darkness, algae, bacteria, and other environmental conditions。 The findings give scientists a powerful new way to reconstruct how ancient megafauna remains entered and survived in submerged cave systems
Ultrafast X-rays revealed how a molecule converts absorbed light into motion in just trillionths of a second。 Individual atoms recorded different stages of the process, opening a powerful new window into light-driven chemistry

A new chemical process can transform three of the most common plastics into high-purity hydrogen without sorting them first。 The technique operates at much lower temperatures than traditional gasification and captures most of the plastic’s carbon in solid or liquid forms instead of releasing it as carbon dioxide
Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein。 In mice, arginine-rich diets led to fewer colon tumors and milder viral infections, suggesting a simple supplement could have powerful therapeutic potential
NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy。 The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black hole about a million times the Sun’s mass
Global warming appears to have shifted into a faster gear。 After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0。35°C per decade over the past ten years, compared with just under 0
