Natural variations help resolve a climate puzzle
New research shows that naturally occurring climate variations help to explain a long-standing difference between climate models and satellite observations of global warming.

A team of researchers from Stanford University and the University of California has developed a microstructured material with spatial variation causing friction in only one direction. In their paper published in Journal of ...
For nearly 100 years, biologists have argued about how exactly natural selection can possibly work. If nature selects the individuals with the best genes, then why aren't all organisms the same? What maintains the genetic ...
