Leafy vegetables like lettuce are readily available in grocery stores and often seen as a healthy food choice. As researchers work to understand how emerging contaminants behave in plants, new research is shedding light on ...

When a cocaine addict relapses, it isn't a matter of personal failure—it's the biological result of their brain's rewiring, new research finds. Michigan State University scientists have found that cocaine changes how the ...

For the first time, the Tibet ASγ Experiment has successfully measured magnetohydrodynamic (MHD) turbulence on scales below one parsec (approximately 3.3 light-years) within the gamma-ray halo surrounding the Geminga pulsar ...

Major depressive disorder (MDD) is one of the leading causes of disability worldwide, and approximately 30% of patients develop treatment-resistant depression (TRD), a condition that does not respond adequately to conventional ...

Psilocybin—the psychoactive compound in "magic mushrooms"—is gaining scientific attention for its potential in treating neuropsychiatric conditions including depression, anxiety, substance use disorders and certain neurodegenerative ...

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 ...

The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of which can overheat under stress, causing steep drops in performance. To address this, a team led by ...

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 ...
