A potent clot-busting substance originally extracted from the saliva of vampire bats may be used up to three times longer than the current stroke treatment window – without increasing the risk for additional brain damage, according to research reported in todays rapid access issue of Stroke: Journal of the American Heart Association.
The vampire bat saliva-derived clot buster is called Desmodus rotundus salivary plasminogen activator (DSPA) or desmoteplase. DSPA targets and destroys fi
The secret to its strength is a ring, Weizmann Institute researchers report in Science
Weizmann Institute scientists have found what makes the bacterium Deinococcus radiodurans the most radiation-resistant organism in the world: The microbe’s DNA is packed tightly into a ring. The findings, published in the January 10 issue of Science, solve a mystery that has long engaged the scientific community.
The red bacterium can withstand 1.5 million rads – a thousand times more tha
A University at Buffalo chemist has developed a new, high-throughput method for obtaining nuclear magnetic resonance (NMR) data that not only has the distinction of potentially performing orders of magnitude faster than conventional methods, but does so more cheaply and with greater precision.
The new method, described in the current online issue of the Journal of the American Chemical Society, has the potential to increase greatly the use of high-throughput NMR to determine protein structu
Nanoshell sensor opens door for new methods to exam single molecules
Nanotechnology researchers at Rice University have demonstrated the ability to precisely control the electromagnetic field around nanoparticles, opening the door for chemical screening techniques that could allow doctors, life scientists and chemists to routinely analyze samples as small as a single molecule.
The research is detailed in the current issue of Applied Physics Letters. It builds upon a widely u
A new type of star has been discovered lurking as a low mass component in a very compact binary star system.
Astronomers Steve B. Howell of the University of California, Riverside and Tom Harrison of New Mexico State University, Las Cruces, announced today at the American Astronomical Society Meeting in Seattle, Wash., that they have confirmed the existence of a new variety of stellar end-product. This previously unknown type of star has some properties similar to brown dwarf stars and may
University of Georgia researchers studying rice genomes under a National Science Foundation Plant Genome Research Program award have identified the species first active DNA transposons, or “jumping genes.” The research is published in the Jan. 9 edition of the journal Nature. In collaboration with researchers from Cornell, Washington University and Japan, geneticist Susan Wessler also discovered the first active “miniature inverted-repeat transposable element,” or “MITE,” of a
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually…
