Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons work similarly. To move against a str…
Science fiction suggests that life on other planets, if it exists, is likely far more advanced than life on Earth. A recent study suggests otherwise.

Exoplanets are exotic worlds orbiting distant stars far beyond our solar system. Ever since the first ones were discovered in the 1990s, astronomers have turned their attention to these distant worlds to understand more about them. Now, for the first time, sc…
New research has pinned down the onset of the "RNA World," a hypothetical time in Earth's very early history when RNA was the primary replicating substance.
An international team of astronomers from ASTRON, JIVE, the University of Amsterdam and other institutions has found the first so-called "microblazar" in the Milky Way. This stellar system is composed of a massive star and a black hole with a jet that is poin…
A tiny, single-celled organism can thrive at temperatures that would kill all other known complex life. In a study published in Cell, scientists describe a new species of amoeba that can eat and reproduce in hot spring water as warm as 63°C (145°F) in Califor…
When giant systems of ancient caves far below the surface of Australia collapsed, it left distinctive clues at the surface.
The haunting beauty of the universe is on full display in this year's astrophotography competition.

Half of our genome is made of transposons — snips of DNA that can move and copy themselves. But they’re more than parasites or genetic junk.
Philosophers have wrestled with this riddle for centuries, but evolutionary biology has quietly been building a case that rewrites the entire question. The answer turns out to hinge on a single, strange genetic moment that has almost nothing to do with chicke…
