An environmental engineer at Washington University in St. Louis has created a device similar to a hydrogen fuel cell that uses bacteria to treat wastewater and create electricity.Lars Angenent, Ph.D., an assistant professor of Chemical Engineering, and a member of the University's Environmental Engineering Science Program, has devised a microbial fuel cell which he calls an upflow microbial fuel cell (UMFC) that is fed continually. Beowulfand Angelina Jolie Give 3-D a Second Chance in Hollywo
Once a nausea-inducing fad, 3-D is staging a comeback -- more than 50 years after its first run. When Beowulfcomes out in November, it will premiere on nearly 1,000 3-D screens -- the most ever. Star role for bacteria in controlling flu pandemic
Bacteria synthesis starting material for antiflu drug Bio-archaeologists Pinpoint Oldest Northern European Human Activity
Scientists at the University of York used a 'protein time capsule' to confirm the earliest record of human activity in Northern Europe. A team of bio-archaeologists from York were able to provide the final piece of scientific evidence which confirmed that primitive stone tools discovered in East Anglia dated back around 700,000 years -- 200,000 years earlier than any other traces of human colonisation of northern latitudes. Engineering The 'Super Enzyme' -- A Potential New Weapon Against Heart

A group of Japanese scientists has used gene therapy to deliver three insulin transcription factors, MafA, PDX-1, and NeuroD, to the livers of diabetic mice. As a result, the mice experienced an increase in insulin gene expression and insulin production, raising the possibility that this could eventually be used to treat diabetes. Greenroofs 101
