Severe climate changes during the last ice-age could have been caused by random chaotic variations on Earth and not governed by external periodic influences from the Sun. This has been shown in new calculations by a researcher at the Niels Bohr Institute, Copenhagen University.

King Alfred burned the cakes, right? Wrong.

A project by University of Wisconsin-Madison researchers has come one step closer to making fusion energy possible.

The research team, headed by electrical and computer engineering Professor David Anderson and research assistant John Canik, recently proved that the Helically Symmetric eXperiment (HSX), an odd-looking magnetic plasma chamber called a stellarator, can overcome a major barrier in plasma research, in which stellarators lose too much energy to reach the high temperatures needed for fusion.

The first detailed images of an elusive drug target on the outer wall of bacteria may provide scientists with enough new information to aid design of novel antibiotics. The drugs are much needed to treat deadly infections initiated by Staphylococcus aureus and other bacterial pathogens.

The research team, led by Natalie Strynadka, a Howard Hughes Medical Institute (HHMI) international research scholar at the University of British Columbia in Vancouver, Canada, published its findings in the March 9, 2007, issue of the journal Science.

High performance schools integrate the best in today's design strategies and building technologies. Even better, they make a difference in the way children learn. Research has shown that better buildings produce better student performance, reduce operating costs and increase average daily attendance. They also are more likely to maintain teacher satisfaction and retention and reduce liability exposure.

Deane Evans, FAIA, executive director of the Center for Architecture and Building Science Research at New Jersey Institute of Technology (NJIT), numbers among the nation's top boosters for high-performance schools.

Cuttlefish are well-known masters of disguise who use highly developed camouflage tactics to blend in almost instantaneously with their surroundings. These relatives of octopuses and squid are part of a class of animals called cephalopods and are found in marine habitats worldwide. Cephalopods use camouflage to change their appearance with a speed and diversity unparalleled in the animal kingdom, however there is no documentation to date that they use their diverse camouflage repertoire at night.
