Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to encode signals or images. Yet controlling these properties independently remains difficult, especially ...

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 ...

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.

Many Americans remain uneasy about driverless cars. According to new research, their concerns go far beyond safety.

Robust real-world data on the effectiveness of biologic therapies in children with severe asthma remain limited, particularly across different ages and early-life risk profiles. This evidence gap constrains precision in treatment ...

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 ...

Northwestern University engineers have developed the first modular robots with athletic intelligence. They can be combined and recombined in the wild, recover from injury and keep moving no matter what's thrown at them.
