Astronomers discover dying stars eating their planets

Astronomers have discovered that aging stars may be devouring their closest giant planets as they swell into red giants. Using NASA’s TESS telescope to study nearly half a million stars, scientists found far fewer close-orbiting planets around older, expanded stars—clear

Scientists find hidden brain source that fuels dementia

Weill Cornell researchers uncovered how free radicals from astrocyte mitochondria can fuel dementia. Using new compounds that target these radicals at their source, they slowed brain inflammation and neuronal damage in mice. The findings reveal a potential breakthrough for

Do you speak cat? Take this quiz to find out

While often miscast as mysterious or hard to understand, cats are actually excellent communicators. In fact, in free-ranging cat colonies, physical fights are kept to a minimum through clever use of body posturing, scent exchange and vocalizations.

An international team of researchers, including scientists from the Museum für Naturkunde Berlin, has uncovered a surprisingly complex nervous system in sea urchins. The animals appear to possess an "all-body brain" whose genetic organization resembles that of the vertebrate

Urban fungi show signs of thermal adaptation

A new study from researchers at the Johns Hopkins Bloomberg School of Public Health finds that common fungal species may be adapting to higher temperatures in warmer sites within cities compared to cooler sites in the same city.

Extended defects unlock new properties in nanomaterials

Materials scientists at the University of Minnesota Twin Cities have found a way to create and control tiny "flaws" inside ultra-thin materials. These internal features, known as extended defects, could give next-generation nanomaterials entirely new properties, opening the
