☆ Mirror, Mirror on the Wall, Cock-a-Doodle-Doo
  + stars: | 2023-10-25 | by ( Darren Incorvaia | ) www.nytimes.com   time to read: +2 min
“They are way smarter than you think,” Ms. Hillemacher said. Now, in a study published in the journal PLOS One on Wednesday, Ms. Hillemacher and her colleagues say they have found evidence that roosters can recognize themselves in mirrors. The mirror test is a common, but contested, test of self-awareness. The mirror test has since been used to assess self-recognition in many other species. But different cognitive processes are active in different situations, and there’s no reason to think that the mirror test is accurate for animals with vastly different sensory abilities and social systems than what chimps have.

☆ This Tiny Parasitic Wasp Can Drill Through Plastic
  + stars: | 2023-09-21 | by ( Darren Incorvaia | ) www.nytimes.com   time to read: +1 min
By the time Matvey Nikelshparg was 13, he was obsessed with parasitoid wasps, tiny insects that lay their eggs on or inside other bugs. Under a microscope in a lab he had assembled at home, he discovered that one species had a startling superpower: It could use an organ that protrudes from its abdomen to drill through a plastic petri dish. Eupelmus messene is a whisper of a wasp. The insect’s target is the larvae of other wasp species, which lay their eggs inside of galls in an effort to protect them from danger. In his experiments at home, Mr. Nikelshparg had set out to study what would happen if there were multiple E. messene wasps and only one host larva.

☆ SpongeBob Lives in a Pineapple. These Sharks Live in Sponges.

John Pogonoski, an ichthyologist in Australia, wasn’t about to be fooled by any moray eels. He knew the serpentine fish like to hide among the nooks and crannies of large sponges. But as he surveyed sponges collected from a remote seabed off the coast of Western Australia, he stumbled on a complete surprise — a small shark tail poking out of a sponge’s cavernous body. “Sponges, though, this is new.”The word “shark” may conjure images of gargantuan great whites or hefty hammerheads. The banded sand catshark, maxing out around a foot and a half in length, is on the smaller end of the spectrum.

☆ You Really Are a Tick Magnet
  + stars: | 2023-06-30 | by ( Darren Incorvaia | ) www.nytimes.com   time to read: +1 min
The tiny arachnids spread a variety of harmful diseases, as they expand their range to new areas. But two scientists recently set out on a counterintuitive mission to collect as many bloodsucking ticks as possible. Dr. Lihou is a veterinary parasitologist who studies ticks, and Dr. England is an ecologist who studies electricity and electroreception. The resulting paper, published Friday in the journal Current Biology, provides a new reason to worry about ticks. While the finding may add to ticks’ terrifying attributes, this knowledge could also be used to improve antistatic tick defenses.

☆ These Flies Age Faster After Witnessing Death
  + stars: | 2023-06-13 | by ( Darren Incorvaia | ) www.nytimes.com   time to read: +1 min
Dr. Pletcher and Dr. Gendron found that flies that had seen corpses were avoided by other flies, as if they’d been marked by death (how this works is still a mystery). The two scientists housed living flies in vials with fly cadavers for two days, and tracked their brain activity with a fluorescent green dye. Dr. Gendron and Dr. Pletcher then identified the key neurons in the ellipsoid body. When these were shut off, seeing dead flies did nothing to the life span of the living. When the researchers activated those neuron clusters, flies met their maker sooner, even if they had never been exposed to dead flies.

The great apes do not have spoken language, but they share many gestures. Can humans like you understand those gestures too? Watch this short video and test your ability to read chimpanzee body language.
