Wonder material graphene has been touted as the next silicon, with one major problem -- it is too conductive to be used in computer chips. Now scientists have given its prospects a new lifeline. Scientists have now literally opened a third dimension in graphene research. Their research shows a transistor that may prove the missing link for graphene to become the next silicon.

A study that combines experimental observations of spider webs with complex computer simulations has shown that web durability depends not only on silk strength, but on how overall web design compensates for damage and the response of individual strands to continuously varying stresses.

The active learning algorithm is faster and more accurate in guessing the age of an individual than conventional algorithms.
