Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date, which works by absorbing heat generated by incoming light. Capable of capturing light from the entire electromagnetic ...

A year after stopping taking weight-loss drugs such as Ozempic and Wegovy, people regain—on average—60% of their lost weight. But beyond this, their regained weight plateaus, with individuals managing to keep off 25% ...

For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many flowering trees—sometimes ...

All complex biological systems—like the DNA, RNA and proteins constantly being copied and built within our cells—are prone to errors. That means as life evolved to be more elaborate, it also had to evolve error-correcting ...

Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed during a cell's life, but they also regulate cell death, calcium balance, and responses to stress. ...

Many engineering challenges come down to the same headache—too many knobs to turn and too few chances to test them. Whether tuning a power grid or designing a safer vehicle, each evaluation can be costly, and there may ...

Initial tests with a natural dye produced by the Amazonian fungus Talaromyces amestolkiae show that eco-friendly cosmetics, such as face creams, gel sticks, and shampoos, can be developed with antioxidant and antibacterial ...

Recently-revealed notebooks belonging to a late paleontologist contain the missing information needed to help researchers finish their study of a remarkable fossil discovered nearly three decades ago.

Japanese red elder plants safeguard their own survival when they drop fruits infested by Heterhelus beetle larvae, as well as the survival of these larvae. A Kobe University study changes the narrative on how a plant and ...

After more than a decade of research, scientists have discovered the natural mechanism behind a novel form of cell death called ferroptosis. The work, described in the current issue of Cell, points toward an entirely new ...

A new study published in Science is challenging long-held assumptions about how we measure genetic risk in endangered species. Researchers analyzed whole genomes from hundreds of koalas, finding that populations previously ...

Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic method for quantum computers. It makes errors in individual quantum bits visible during logical ...
