Scientists Reveal How Cells Tame One of Biology’s Most Dangerous Metals

Polyamines may protect cells from toxic iron buildup by keeping reactive iron under control. Iron keeps cells alive, but when too much of it remains chemically reactive, the same metal can become destructive. Excess free iron can drive reactions that damage DNA, proteins, and cell membranes, creating a problem cells must constantly control. Whitehead Institute […]

Blackbirds Somehow Know When a Snake Is Too Dangerous To Attack

Red-winged blackbirds largely avoided striking rattlesnakes while aggressively attacking gopher snakes, revealing a striking difference in nest defense behavior. At nests across western Oregon, red-winged blackbirds readily confronted many threats to their young, but rattlesnakes prompted a strikingly different response. Even though the birds likely had little or no experience with vipers, they were remarkably […]

Scientists Find a Clue to Making Brain Stimulation More Reliable

The brain’s activity immediately before stimulation may help predict its response and improve the consistency of neuromodulation. The same brain stimulation can produce very different responses depending on when it is delivered. A study published in Brain Stimulation, using detailed brain recordings hosted by EBRAINS, suggests that the brain’s activity immediately before stimulation can explain […]
