World’s deepest zoo harbors clues to extraterrestrial life
Scientists have found a wide range of life deep below Earth’s surface. The discoveries could help inform our search for life on other planets.
- Physics
Gravitational waves detected yet again
For the third time in 16 months, scientists have announced detection of gravitational waves washing over the spacetime environment in which Earth resides. This seems to show that such waves may not be rare.
- Archaeology
European fossils may belong to earliest known hominid
New fossils suggest that the earliest non-ape human ancestors may have evolved in Europe, not Africa.
- Climate
Ancient Arctic ‘gas’ melt triggered enormous seafloor explosions
Methane explosions 12,000 years ago left huge craters in bedrock on the Arctic seafloor. Scientists worry more could be on the way today as Earth’s ice sheets melt.
- Animals
Analyze This: A massive annual insect migration
A study of seasonal insect migration gave some surprising results.
- Animals
How a flamingo balances on one leg
Flamingos are so good at balancing on just one leg that they can snooze that way with little effort.
- Animals
Scientists Say: Extremophile
Some species can survive high heat, freezing cold or other extreme environments. Scientists call these organisms extremophiles.
- Chemistry
New rules point scientists toward next-gen germ-killers
Shape and other features help germ-killing drugs make it through barriers to enter bacteria. Knowing how they do this could lead to more and better better antibiotics.
- Fossils
Study claims to have found oldest human fossils
Humans, as a species, may be much older than previously thought. They also may have evolved further North and West of the suspected cradle of human evolution.
- Genetics
Cool Jobs: New tools to solve crimes
Future investigators may identify criminals by the microbes they leave behind or by using DNA-like evidence from strands of their hair.
- Planets
Jupiter gets surprisingly complex new portrait
NASA’s Juno spacecraft has sent back unexpected details about Jupiter, giving scientists their first close-up of this gas giant.
