Cell replication in our bodies is triggered by a cascade of molecular signals transmitted between proteins. Compounds that block these signals when they run amok show potential as cancer drugs.

How tomato plants use their roots to ration water during drought

Plants have to be flexible to survive environmental changes, and the adaptive methods they deploy must often be as changeable as the shifts in climate and condition to which they adapt. To cope with drought, plant roots produce ...

Researchers have uncovered both the mathematical and biological mechanism behind the rugged structures at cell boundaries found in tissues such as the kidneys and nasal glands. The team hopes that their new insights can help ...

Hubble finds Saturn's rings heating its atmosphere

The secret has been hiding in plain view for 40 years. But it took the insight of a veteran astronomer to pull it all together within a year, using observations of Saturn from NASA's Hubble Space Telescope and retired Cassini ...

Software assembles complete genome sequences on-demand

National Institutes of Health researchers have developed and released an innovative software tool to assemble truly complete (i.e., gapless) genome sequences from a variety of species. This software, called Verkko, which ...
