As the immune system weakens with age, scientists have found a way to restore some of its lost strength. By delivering mRNA to the liver, they created a temporary source of immune-boosting signals that normally come from the thymus. Older mice ...

Researchers have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons process incoming information before sending signals ...

A new catalyst design could transform how acetaldehyde is made from renewable bioethanol. Researchers found that a carefully balanced mix of gold, manganese, and copper creates a powerful synergy that boosts efficiency while lowering operating ...

Mars isn't just dusty--it crackles with electricity. Scientists discovered that dust devils can generate tiny electric sparks, captured for the first time by Perseverance's microphone. These static discharges may rapidly destroy chemicals like ...

Scientists have uncovered ancient wolf remains on a small Baltic island where wolves could only have been brought by humans. These animals weren't dogs, but true wolves that ate the same marine food as the people living there and showed signs of ...

Scientists have detected the most distant supernova ever seen, exploding when the universe was less than a billion years old. The event was first signaled by a gamma-ray burst and later confirmed using the James Webb Space Telescope, which was able . ...

Tiny lab-grown brains are offering an unprecedented look at how schizophrenia and bipolar disorder disrupt neural activity. Researchers found distinct electrical firing patterns that could identify these conditions with high accuracy. The discovery . ...

Scientists have uncovered why big predators like sharks spend so much time in the ocean's twilight zone. The answer lies with mid-sized fish such as the bigscale pomfret, which live deep during the day and rise at night to feed, linking deep and ...

Researchers say fusion reactors might do more than generate clean energy--they could also create particles linked to dark matter. A new theoretical study shows how neutrons inside future fusion reactors could spark rare reactions that produce axions, ...

Weight loss restored healthy metabolism in both young and mid-aged mice, but the brain told a different story. In mid-aged animals, slimming down actually worsened inflammation in a brain region tied to appetite and energy balance. While this ...
