A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists at UC Davis and the Smithsonian Institution. The new analysis puts Perucetus colossus back in the same weight range as

In a new study, scientists have discovered that viruses that infect microbes contribute to climate change by playing a key role in cycling methane, a potent greenhouse gas, through the environment.

A promising new fungicide to fight devastating crop diseases has been identified by researchers at the University of California, Davis. The chemical, ebselen, prevented fungal infections in apples, grapes, strawberries, tomatoes and roses and improved sym

Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs.

What is the origin of genetic diversity in plants? Can new mutations acquired during growth be passed on to seeds? INRAE scientists, in collaboration with CIRAD and the CNRS, have used the French Guiana forest as the setting for their research, leading to

Human bodies make 2 million red blood cells per second. They each live for 120 days and spend that time zooming completely around the body every 20 seconds, carrying oxygen from the lungs to other tissues and bringing back carbon dioxide that is exhaled.

Human-caused environmental changes threaten natural ecosystems. These ecosystems are essential to creating and maintaining a rich, resilient, and adaptable biosphere. In East Africa's savanna, antelope populations are vital for a healthy and functioning
