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.
Scientists at MIT have taught a microbe a new trick: They've tinkered with its genes to persuade it to make fuel - specifically, a kind of alcohol called isobutanol that can be directly substituted for, or blended with, gasoline.
Scientists of the German Cancer Research Center have developed 'RNA switches' which allow them to specifically turn on and off genes in viruses. This will help to enhance regulation of gene therapy and viral therapy of cancer.
While your DNA is unique, it also tells the tale of your family line. It carries the genetic history of your ancestors down through the generations. Now, says a Tel Aviv University researcher, it's also possible to use it as a map to your family's past.
Experts agree that, more than ever before, modern wars will be fought in the cyber zone, targeting an enemy's communications technology to cause untold damage. Now a Tel Aviv University researcher is suggesting that the same tactics should be employed in the battle against one of the body's deadliest enemies - cancer.
Even after being frozen for 18 years, human embryos can be thawed, grown in the laboratory, and successfully induced to produce human embryonic stem cells, which represent a valuable resource for drug screening and medical research.
