Phys.org / What's in your salad? Crops exposed to nanoplastics may boost heavy metal intake
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 ...
Medical Xpress / How cocaine rewires the brain to drive relapse
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 ...
Phys.org / What Geminga's 100 TeV cutoff may mean for cosmic-ray acceleration in the Milky Way
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 ...
Medical Xpress / PET imaging study reveals how ketamine relieves treatment-resistant depression
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 ...
Medical Xpress / Creating less trippy, more therapeutic 'magic mushrooms'
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 ...
Phys.org / Möbius-inspired surface controls light in two directions
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 ...
Phys.org / Trapping light on thermal photodetectors shatters speed records
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 ...
Medical Xpress / Quitting GLP-1 drugs triggers rapid regain, but 25% of weight loss may last
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% ...
Phys.org / Radiocarbon dating rewrites angiosperm trees' lifespan records worldwide
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 ...
Tech Xplore / Tiny thermometers offer on-chip temperature monitoring for processors
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 ...
Phys.org / Understanding how cells take up and use isolated mitochondria to restore energy function
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. ...
Tech Xplore / 'ChatGPT for spreadsheets' helps solve difficult engineering challenges faster
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 ...
