| 3-D
structure of anthrax toxin complex solved: Scientists have
determined a three-dimensional (3-D) molecular image of how anthrax toxin
enters human cells, giving scientists more potential targets for blocking
the toxin, the lethal part of anthrax bacteria. |
| New
technology could transform every train into a high speed cracked rail detector:
Researchers in the University of Warwick's Department of Physics have developed
a novel non-contact method of using ultrasound to detect and measure cracks
and flaws in rail track - particularly gauge corner cracking - that has
the potential to simply be attached to a normal passenger or freight train
travelling at high speeds. |
| Climate
may play role in lynx's hunting ability: Snow quality may affect
the Canadian lynx's ability to kill its prey, according to new research
suggesting climate may be impacting one of the most fascinating ecological
systems to intrigue biologists for decades. |
| Bacterial
toxin may protect infants from asthma: Children whose homes
contain high levels of endotoxin, a bacterial compound that collects in
house dust, may be less likely to develop eczema during their first year
of life. |
| Ginseng
reduces effects of anti-clotting drug: Researchers from the
University of Chicago report in the July 6, 2004, issue of the Annals of
Internal Medicine that ginseng, one of the best selling herbal supplements
in the United States, interferes with warfarin, a drug commonly used to
prevent blood clots. |
| Arctic
yields fresh evidence for Elizabethan gold swindle: Canadian
scientists say they've found conclusive proof that a tiny, barren Arctic
island was the site of Canada's first, and perhaps greatest, mining fraud. |
