Rutgers Researchers Find a 'Great Fizz' of Carbon Dioxide at the End of the Last Ice Age
Wed, 01 Sep 2010 13:22:00 -0500
Imagine loosening the
screw-top of a soda bottle and hearing the carbon dioxide begin to escape. Then imagine taking the cap off quickly, and seeing the beverage foam and fizz out of the bottle. Then, imagine the pressure equalizing and the beverage being ready to drink. Rutgers marine scientist Elisabeth Sikes says that something similar occurred over a 1,000 year period after the end of the last ice age--or glaciation, as scientists call it.

Researchers from North Carolina
State University have developed extremely small microneedles that can be used to deliver medically relevant nanoscale dyes, called quantum dots, into skin--an advance that opens the door to new techniques for diagnosing and treating a variety of medical conditions, including skin cancer.

A unique experiment at Rice University that forces bacteria into a head-to-head competition for
evolutionary dominance has yielded new insights about the way Darwinian selection plays out at the molecular level. An exacting new analysis in the journal Molecular Systems Biology reveals precisely how specific genetic mutations impart a physical edge in the competition for survival.

A collaborative team of scientists has made a
significant advance in the breakthrough discovery last year by Sean Cutler of the University of California, Riverside, of pyrabactin, a synthetic chemical that mimics a naturally produced stress hormone in plants to help them cope with drought conditions. Reporting that they have a clearer understanding of how pyrabactin works, the scientists say other, more effective chemicals for bringing drought-resistance to plants can now be developed.

A team of researchers led
by Hernan Makse, professor of physics at The City College of New York (CCNY), has shed new light on the way that information and infectious diseases proliferate across complex networks. Writing in Nature Physics, they report that, contrary to conventional wisdom, persons with the most connections are not necessarily the best spreaders.

Drug resistant bacteria are a problem in many environments, especially healthcare institutions. While the ways in which these cells become resistant are understood at the cellular level, until now, the bacteria's survival strategies at the population level remained unclear.
A new study by James Collins and colleagues at Boston University and the Wyss Institute for Biologically Inspired Engineering at Harvard University reveals that a surprisingly small percentage of bacteria actually ...
