High-fructose corn syrup triggered a stronger response and was preferred by the animals. The findings suggest that the type of sugar—not just the calories—can influence appetite and food preferences.

If future missions detect life there, there's a surprising chance it didn't originate on Venus at all—it may have come from Earth.

Einstein Probe may have caught a black hole tearing apart a white dwarf for the first time

Astronomers may have witnessed one of the rarest and most dramatic cosmic events ever seen: a long-sought intermediate-mass black hole ripping apart a dense white dwarf star and devouring it. The Einstein Probe space telescope caught the explosion in its earliest moments, revealing an unusual sequence of intense X-ray flashes unlike anything seen in a typical gamma-ray burst.
