It looks like Sony and Toshiba can get along after all. This comes hot on the heels of this year's final stage of the Blu-ray versus HD DVD war, which prompted many to believe that these two companies would never see eye to eye, not in the near future nor the distant one. However, going against this comes the ne... |

DNA is the irrefutable proof in many outstanding criminal cases. However, about 250,000 DNA samples aimed to detect a rapist can remain anywhere from 3 to 12 months in forensic laboratories backlogs, and this gives suspects more than enough time to make themselves disappear. The issue could be solved by Jessica Voorh... |

There are cases when death can be a really good thing. Imagine, for instance, the cancer cells. However, so far, only two ways of cell death have been known: apoptosis (when the cell destroys itself) and phagocytosis (when the cell is digested by another cell). Now a new type of cell death has been found: entosis, wh... |
