As automakers ramp up their plans to put greener vehicles on the road, hydrogen storage has become a pivotal issue. Whereas it's been suggested that graphene could play an important role in retaining hydrogen for use in fuel cells and other technologies, a team of researchers at the National Institute of Standards and Technology (NIST) and the University of Pennsylvania in Philadelphia say they've found a way to configure graphene that enables it to hold 100 times more hydrogen molecules than a single layer of the carbon-based substance...
Once they're inside the female reproductive organs, sperm pull out all the stops to outrace their rivals to the egg—especially if the opponent comes from another male.
The 23,000 protein-coding genes in the human genome can help determine whether a person will have blond hair or black, flat feet or arched. But that's hardly the whole story behind the millions of tiny differences among people...
