Popular AI-powered food apps may make calorie counting easier, but they may also leave out a surprisingly large part of the meal。 Four apps underestimated calories and fat by about one-third when tested against carefully prepared meals。 High-fat ketogenic dishes appeared to cause the most trouble, while carbohydrates were measured more consistently
A new analysis has precisely dated paintings in France’s Font-de-Gaume cave for the first time。 Scientists discovered charcoal inside black pigments once thought to contain only minerals, allowing them to use radiocarbon dating。 The results show that a bison was painted about 13,000 years ago, while sections of a mask-like figure were added during
The outage affected gamers' ability to launch games, apps or network features on their PlayStation
HN is great for the links people share, but a big part of the value I get comes from reading the discussion around them。 I realized I was always opening the article in one tab and the comments in another, constantly switching back and forth。I figured there was probably a simpler way, so I threw together this userscript to merge the two
Just launched my app, VimGolf。 As users complete the levels on the map, I introduce progressively more complicated concepts — it’s aimed at people who have never used Vim。 Any feedback would be much appreciated
China’s Tianwen-1 orbiter captured a faint but remarkable view of 3I/ATLAS as the interstellar comet raced past Mars。 The images reveal its tail and glowing coma, offering scientists a glimpse of material born beyond our solar system
Sweden could become an important source of rare earth elements needed for magnets and green technologies。 Instead of extracting one target metal, researchers are cataloging everything contained in Swedish mineral deposits。 They will then develop magnets using those naturally available combinations, potentially reducing pollution, waste, and relianc
Giant sequoias are built to withstand ordinary fires, but recent extreme wildfires killed thousands of trees that had survived for centuries or even millennia。 A new analysis of about 26,400 sequoias found that trees in areas treated with prescribed burns were nearly four times more likely to survive。 Researchers estimate the controlled fires preve
