For countless ages, a small chunk of ice and dust traveled alone through interstellar space, like a sealed bottle drifting across a vast cosmic sea. This summer, that traveler entered our solar system and received the name 3I/ATLAS, becoming only the third confirmed interstellar comet ever observed. When researchers at…

Almost every forest bird in Hawaiʻi is spreading avian malaria

Astronomers shocked by how these giant exoplanets formed

Gas giants are enormous planets made primarily of hydrogen and helium. They may contain dense central cores, but unlike Earth, they do not have solid surfaces you could stand on.

Scientists just made living blood vessels on a chip that act like real ones

Human blood vessels are anything but simple. They bend, branch, narrow, and widen, creating complex pathways that affect how blood moves through the body. For a long time, however, laboratory models treated blood vessels as straight, uniform tubes. While useful, those simplified designs failed to reflect the conditions where many…

Scientists discover how life experiences rewrite the immune system

This wide range of outcomes raises a fundamental question. Why do two people exposed to the same pathogen respond so differently? A major…
