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 ...

Environmental damage caused by human activity can reduce the number of plant and animal species dramatically. At the same time, very little is known about how biodiversity recovers after ecosystem pollution is curtailed and ...
