Space Bacteria
Wherever humans go, our bacterial companions will follow. That’s as true in space as it is on Earth, and while we’ve known that microbial astronauts are present on the International Space Station, one group of researchers has just found a new reason to worry about them.
A genomic analysis of sam ...read more
An Adventure to Venus
Though widespread interest in Venus has somewhat waned over recent decades, India’s upcoming mission aims to turn that tide.
As part of a still unnamed mission, ISRO will launch an approximately 5,500-pound (2,500-kilogram) spacecraft aboard the heaviest rocket they currently operate: the Geosynchronous Satellite Launch Vehicle Mark III. The sheer size and power of this three-stage rocket will enable the spacecraft to ferry a full suite of instruments, weighing up to ...read more

A Strange New Galaxy
An unusual, enormous, and ancient dwarf galaxy looms near the Milky Way, 424,000 light-years away from Earth in the Antlia constellation, a new study found using data from the European Space Agency’s (ESA) Gaia spacecraft.
Scientists estimate that dozens o ...read more

In chimpanzee societies, a whistle followed by a high-pitched hoot seems to mean, “I’m leaving.” Energetic grunts probably say “good food.” And a hip thrust could signal that chimp is ready to get frisky.
These rough translations result from decades of research on chimp communication. In addition to revealing what apes are saying (big surprise: food and sex), the results also reflect why and how chimps communicate — and how this ...read more
