It may be small, its habitat harsh, but a newly discovered single-celled microbe leads the hottest existence known to science. Its discoverers have preliminarily named the roughly micronwide speck “Strain 121” for the top temperature at which it survives: 121 degrees Celsius, or about 250 degrees Fahrenheit. Announcing Strain 121’s record-breaking ability to take the heat in the August 15 issue of the journal Science, researchers Derek Lovley and Kazem Kashefi write, “The upper

Today, (August 14th), sees the start of data collection on the Main Injector Neutrino Oscillation Search (MINOS) detector, situated in the Soudan iron mine, Minnesota, USA. UK particle physicists, working within an international collaboration, will use the MINOS detector to investigate the phenomenon of neutrino mass – a puzzle that goes to the heart of our understanding of the Universe.

Neutrinos are pointlike, abundant particles with very little mass. They exist in three types or ‘flavour

A New Tool for Biology and Medicine

La Jolla, CA. August 14, 2003—Henry Ford revolutionized personal transportation by introducing an unusual car design onto the auto market and by embracing factory mass production of his “Tin Lizzie.”

Now a team of investigators at The Scripps Research Institute (TSRI) and its Skaggs Institute for Chemical Biology in La Jolla, California is introducing revolutionary changes into the genetic code of organisms like yeast that allow these cel

A 106,000-year-long record of nitrous oxide concentrations and a shorter record of nitrogen and oxygen isotopes show that both marine and terrestrial nitrous oxide production increased in unison and effectively by the same proportional amount during the end of the last glacial period, according to Penn State researchers.

Equal terrestrial and marine production of nitrous oxide also suggest that increased storage of carbon in the oceans was not the cause of low atmospheric carbon dioxide dur

For scientists in the field of neurobiology, defining the factors that influence the arousal of brain and behavior is a “Holy Grail.” Research published by Rockefeller University scientists in the Aug. 11 issue of Proceedings of the National Academy of Sciences Early Edition are the first to give a rigorous definition of what is meant by arousal, considered to be at the base of all emotionally laden behaviors. In particular, the researchers, led by Donald W. Pfaff, Ph.D., provide an operational defi

Electricity moves across miles in seconds to power manufacturing and utilities nationwide. But, for all its speed, the loss of just fractions of seconds of electric power is costing the U.S. economy $100 billion a year.

“The nation’s electric grid is operating so close to capacity that many of today’s electric load demands for fast and dynamic voltage support cannot be provided fast enough,” says Alex Huang, professor of electrical and computer engineering at Virginia Tech.
