High in the Sierra Nevada, a mountain chickadee drops onto an aluminum frame strung with eight identical feeders, hesitates, hops to the wrong one, then the wrong one again, before finally finding the single door that yields a sunflower seed. The bird flits off to cache it. Every visit, every fumble, every clean hit is ...

On a termite mound somewhere in the Limpopo bush, a dwarf mongoose hauls itself up onto its hind legs, scans the scrub, and starts to sing.

The swing of a leg lasts less than half a second. In that sliver of time, the foot leaves the ground, travels forward, and lands again, and the brain has to orchestrate the whole thing while keeping the body upright. For people with Parkinson’s disease, that orchestration falters. Steps shorten, lurch, lose their symmetry, and ...

Three elongated vertebrae, sheathed in a pale fuzz of microbial mat, resting in the dark almost 6,800 meters below the surface of the Indian Ocean.

Teach a machine everything we know about the universe, and you might expect it to spot the cracks in that knowledge faster. The opposite can happen.

The glass slide is nothing special. A sliver of brain tumor, fixed in paraffin, sliced thinner than a hair and washed in the same two dyes pathologists have leaned on for more than a century: hematoxylin to stain the cell nuclei a bruised purple, eosin to wash the rest a dusty pink. Hospitals everywhere make these. A scanner turns one into a digital image, and that image goes to a piece of software called Hetairos.

Anyone who has started taking an SSRI knows the cruel little paradox of the first few weeks. You swallow the pill meant to lift your mood, and at first your mood does the opposite.

Cut open a supergiant isopod hauled up from nearly a kilometre down, and the first thing you notice is the stomach.

From a few hundred feet up, a drone can read a whale’s body the way a doctor reads a chart.

Key Takeaways The torpedo bat design aims to move mass toward the sweet spot, but initial tests show similar performance to standard bats. Studies reveal the torpedo bat's sweet spot is slightly closer to the handle, impacting ball speed negatively compared to traditional designs. One tested torpedo bat had a wider sweet spot due to natural wood variability, suggesting some bats may perform better than others.

A bat hanging from a cave ceiling is doing something that looks effortless but is, mechanically speaking, genuinely strange. It isn’t gripping. Not actively, anyway.

Key Takeaways Oligodendrocytes retract instead of dying under stress, leading to potential implications for myelin regeneration. A study found that dasatinib and quercetin significantly demyelinated mouse brains without killing cells, surprising researchers. The effect was worse in younger mice, suggesting they may depend more on energy pathways affected by D+Q. D+Q-treated cells resembled immature oligodendrocytes found in multiple sclerosis, indicating possible reversibility of demyelination.
