Advanced 3D reconstructions of the comb jelly's aboral organ reveal a sensory system far more complex than scientists expected. The organ contains a wide variety of specialized cells and is closely linked to the animal's nerve network, allowing it to ...

For decades, astronomers wondered why most nearby galaxies are speeding away from the Milky Way instead of being pulled in by its gravity. New simulations reveal the answer: our galaxy sits in a gigantic, flat sheet of matter surrounded by huge empty ...

Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a "molecular catapult." In experiments lasting just 18 femtoseconds, researchers at the University of ...

Researchers created an AI-driven liquid biopsy that scans patterns in fragments of DNA circulating in the blood. The system detected early liver fibrosis and cirrhosis--conditions that often go unnoticed until serious damage occurs. By analyzing ...

Scientists have uncovered new genetic rules that determine whether the immune system's "killer" T cells remain powerful long-term defenders or become worn out and ineffective. By building a detailed genetic atlas of CD8 T cell states, researchers ...

A new study shows that as humpback whale populations recover from past whaling, older males are gaining a major advantage in reproduction. Early in the recovery, breeding groups were dominated by younger whales. But as more mature males returned, ...

Researchers at Cornell University have developed a powerful imaging technique that reveals atomic scale defects inside computer chips for the first time. Using an advanced electron microscopy method, the team mapped the exact positions of atoms ...

A sweeping new ALMA image has peeled back the veil on the Milky Way's core, exposing a dense network of cold gas filaments near the central black hole. Stretching across 650 light-years, the survey maps the hidden fuel for star formation in ...

Growing neurons rely on chemical cues to find their targets, but new research shows that the brain's physical properties help shape those signals. Scientists discovered that tissue stiffness can trigger the production of guidance molecules through a ...

Ocean temperatures may be quietly protecting the world from a global drought catastrophe. By analyzing more than a century of climate data, researchers discovered that droughts rarely spread across the planet at the same time, affecting only about 1 ...
