Scientists study atmosphere of Venus through transit images

Two of NASA's heliophysics missions can now claim planetary science on their list of scientific findings. A group of scientists used the Venus transit - a very rare event where a planet passes between Earth and the sun, appearing ...

Swift satellite reveals a black hole bull's-eye

What looks like a shooting target is actually an image of nested rings of X-ray light centered on an erupting black hole. On June 15, NASA's Swift satellite detected the start of a new outburst from V404 Cygni, where a black ...

Bacteria use DNA replication to time key decision

In spore-forming bacteria, chromosomal locations of genes can couple the DNA replication cycle to critical, once-in-a-lifetime decisions about whether to reproduce or form spores. The new finding by Rice University bioengineers ...

Neuroscience-based algorithms make for better networks

When it comes to developing efficient, robust networks, the brain may often know best. Researchers from Carnegie Mellon University and the Salk Institute for Biological Studies have, for the first time, determined the rate ...

Buzz the alarm: Climate change puts squeeze on bumblebees

Global warming is putting the squeeze on bumblebees. In the most comprehensive study ever conducted of the impacts of climate change on critical pollinators, scientists have discovered that global warming is rapidly shrinking ...

A graphene-based sensor that is tunable and highly sensitive
