Scaling up the production of biofuels made from algae to meet at least 5 percent -- approximately 39 billion liters -- of U.S. transportation fuel needs would place unsustainable demands on energy, water, and nutrients, says a new report from the National Research Council.

Using the size of guard cells in fossil plants to predict how much DNA each cell contained (the genome size), researchers have discovered that variations in genome sizes over geological time correlate with atmospheric carbon dioxide levels.

ETH-researchers demonstrate how vaccinia virus manipulates the cellular waste-disposal system and thereby cleverly tricks the cell into assisting the intruders replication. Now, the virologists have turned the tables, using inhibitors of this cellular waste-disposal system as a way to block virus infection.

The detection of specific DNA sequences is central to the identification of disease-causing pathogens and genetic diseases, as well as other activities. But current detection technologies require amplification by polymerase chain reaction (PCR), fluorescent or enzymatic labels, and expensive instrumentation.

Have you ever wondered where our agricultural crops come from? And what were they like thousands of years ago, or hundreds of years ago? Our food crops today are in fact very different from the original wild plants from which they were derived.

Past efforts to predict protein structure have met with limited success, but now a scientific team led by Glenn Butterfoss, and Barney Yoo, research scientists at New York University, in collaboration with investigators from the U.S. Department of Energy?s Lawrence Berkeley National Laboratory (Berkeley Lab), Stony Brook University and Temple University have demonstrated that a computer modeling approach similar to one used to predict protein structures can accurately predict peptoid conformation as well.
