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 ...
