Are memories transferable — or edible?

From elsewhere — Sun, 07 Jun 2026 00:44:53 +0000

Claire L. Evans writes: It was the dead of winter in Boston. The surface of the Charles River was frozen solid. But Zachary Kelso braved the biting cold to finally put to rest a mystery that has haunted neuroscience labs for over half a century. To do that, Kelso, a research assistant in the Harvard lab of the neuroscientist Sam Gershman, needed some worms. Specifically, planarians: arrow-headed flatworms, which are among the simplest creatures to possess a brain and a...

The chemistry of life is not exclusive to life

From elsewhere — Wed, 03 Jun 2026 00:45:11 +0000

Siddhant Pusdekar writes: For 15 years, Sébastien Fontaine has been trying to kill dirt. The biochemist, who runs a lab at the French National Institute for Agriculture, Food, and Environment, wanted to know how much carbon is released by soil — just dirt alone, completely devoid of life. His team sealed dirt into jars and blasted them with sterilizing gamma radiation. Then they waited for the carbon dioxide released by the soil — a sign of ongoing microbial respiration —...

How ecotypes harbor the genetic memory of a species’ past

From elsewhere — Tue, 26 May 2026 00:02:25 +0000

Marlowe Starling writes: When she was a graduate student in the 1970s, the evolutionary biologist Kerstin Johannesson regularly walked the shores of a Swedish archipelago, scanning the ground for pebbles that moved: marine snails. Her adviser, a taxonomist, had tasked her with describing the species present there by documenting their traits. She noticed that snails with thicker shells stayed on the shore, while those with thinner shells seemed to prefer wave-battered rocks, and in between the two habitats were snails...

A vast meshwork of soil-bound fungi governs life aboveground

From elsewhere — Sun, 17 May 2026 23:32:39 +0000

Max G. Levy writes: One Tuesday in June 2025, a white Chevy Suburban set off down the northernmost highway in North America. The sun of Alaska’s polar summer hadn’t set in 40 days, and it wouldn’t set again for another 35. But for Michael Van Nuland, the biologist in the driver’s seat, time was already running out. The SUV, packed with four days of fieldwork essentials — rubber boots for mucking in marshes, GPS for centimeter-level precision, a steel tube...

New finding refines how scientists study animal happiness

From elsewhere — Sat, 16 May 2026 01:30:00 +0000

Science News reports: For nearly a decade, Vincent Bombail has been tickling rats. It’s been a standard technique used in the study of animal happiness. But not all rats particularly enjoy the experience, data show. Female rats prefer gentler, more playful tickling than males, Bombail and his colleagues report April 15 in Biology Letters. The findings suggest that the same physical experience evokes a different emotional response in different individuals, potentially influencing the results of studies on animal happiness. “This...

Are you as easily fooled as AI? Depends what you see in this image

But don’t feel too bad: Even artificial intelligence (AI) is easily fooled, according to a study published today in...

If wings came before flight, what were they for?

From elsewhere — Sun, 10 May 2026 00:31:02 +0000

Lily Burton writes: Flight may be one of evolution’s most iconic innovations, but zoologist Piotr Jablonski is convinced that early wings were first meant to be seen, not to fly. The idea came to Jablonski after studying bird behavior in the American West. He noticed some birds would fling out their wings or fan out their tail feathers to lure insects into the open. Then the birds would catch and eat the bugs. If early winged dinosaurs were the ancestors...

How much of our personalities are determined at birth?

From elsewhere — Tue, 05 May 2026 00:48:32 +0000

Laurie Clarke writes: In 2009, Abdelmalek Bayout faced a nine-year prison sentence in Trieste, Italy, for stabbing and killing a man who had mocked him in the street. Aiming to reduce the sentence, his lawyer made an unusual legal argument. His client’s DNA, he said, indicated the presence of the “warrior gene”, a mutation that decades of scientific research had tied to aggressive behaviour. Because of this, the argument went, he couldn’t be held fully accountable for his actions. The...

Neuroscientists are studying octopuses for insights into how intelligence evolved

From elsewhere — Fri, 01 May 2026 00:45:59 +0000

Nature reports: Three hearts; blue blood; no skeleton; arms like tongues. These are just some of the alien features of octopuses, squid and cuttlefish — members of the cephalopod family. The outlandish list continues. Cephalopod skin can taste chemicals, sense light and change colour and texture rapidly. In many species, the sucker-covered arms can even regenerate. These invertebrates have evolved independently from the vertebrate lineage for more than 600 million years. Their last common ancestor was probably a worm-like creature...
