Chimps steal less from friends, and summer heat is saved for winter

They were assigned to high-intensity intervals, moderate-intensity exercise, or a low-intensity comparison group, and body scans at the start, three months and six months tracked fat and lean tissue 3. High and moderate training both cut fat mass more than the low group did, but only the interval group kept its lean tissue; moderate training came with a small decline in lean muscle 3. "We found that high, medium and low intensity exercises all led to modest fat loss but only HIIT retained lean muscle," said lead author Dr. Grace Rose, in a paper published in Maturitas 3.

Then they built a theft: a "victim" chimp sat in one room with three trays of pineapple, and a rope ran to a second room where the "thief" could yank the trays away or leave the rope alone 94. Chimps stole in 70% of trials with non-friends and 61% of trials with friends 94. Victims got angrier at first when a friend took the fruit but calmed down faster, and thieves showed less hostility when the victim was a bonded pal 94. "Ours is the first study to show that they're able to hold back antisocial behavior with their friends," said first author Oded Ritov 94.

Its spectrum shows we see it when the universe was only about 3 billion years old, which makes this the most distant burst observed, and most of its stars formed within about 30 million years, so the galaxy is full of young ones 71.

The unusual part is the timing: Epic pushes heat into the ground in summer and takes it back out months later 125. In July, server-warmed water goes down a pipe and warms the surrounding rock; in January, water pumped back through the same pipe returns to the surface warmer than it left 125. There is no buried tank and no battery, only rock, which conducts heat poorly and so keeps the warmth near where it was put 125. The article compares it to the plow-pile of snow that survives in the corner of a parking lot until April: less surface for its volume, so less exposed 125.

PLIN4 is mostly active in body fat and skeletal muscle, where it helps package lipid droplets for energy storage, not in neural circuits 74. Six patients had highly disruptive variants, and in four families the identical variant tracked through affected first-degree relatives 74. The work was published in Frontiers in Psychiatry, led by psychiatrist Michael Lutter 74. "This new finding flies in the face of the dogma that the genes that contribute to this disease are expressed in the brain," said MSU's A.J. Robison 74.

The birds came from a conservation-breeding program in Jaisalmer: eggs were collected from wild nests starting in 2019, artificially incubated and hand-reared, and in March 2023 a chick hatched from an egg laid by captive birds, the first recorded captive breeding of the species 205. The Ramdevra and Sam facilities now hold 97 birds, 40 from wild eggs and 57 bred in captivity; the program produced 24 live chicks in 2025 and 29 in 2026 205. Chicks stay with their mothers for four to five months, a period lead veterinarian Dr. Tushna Karkariya says is used to judge whether a bird is ready for release 205.

Three things recurred: local knowledge was valued alongside science, communities played a central role in decisions, and management adapted to local social and environmental conditions 194. According to the report on the work, the deciding factor was the actions of locals, not money 194. Co-author Josh Cinner said the Papua New Guinea site surfaced in his 2016 Nature analysis of nearly 1,700 coral reefs as a global bright spot 194.
