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 […]

New “Invisible” Cell Therapy Could Provide Side-Effect-Free Diabetes Treatment
Testing in diabetic mice lowered blood sugar levels for more than 100 days. Transplanted cells can help treat disease, but the immune system often sees them as intruders and attacks them. Penn State researchers are testing a way around that problem by wrapping therapeutic cells in an ultrathin protective coating that acts like an “invisibility […]
Researchers Solve Two Major Problems Holding Back SiC Electronics
A new bottom gate design takes advantage of the intrinsic properties of SiC. For more than 20 years, silicon carbide – SiC – has been viewed as a promising material for electronics that must function in extreme environments. Yet despite years of research, that promise has rarely translated into practical devices. Researchers at Kyoto University […]

Physicists Hunted a Mysterious Particle – and Found Two Unexpected Structures Instead
A first attempt to produce a mysterious strangeonium state using a photon beam yielded important and unexpected results. Physicists have spent decades trying to organize the growing collection of subatomic particles, yet some of the most unusual discoveries still resist simple classification. At the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility, researchers have […]
