Lightning really does strike more than twice

NASA-funded scientists have recently learned that cloud-to-ground lightning frequently strikes the ground in two or more places and that the chances of being struck are about 45 percent higher than what people commonly assume.

Recently, William C. Valine and E. Philip Krider in the Institute of Atmospheric Physics at the University of Arizona, co-authors of the study, took to the field using video and other technology to study lightning, which is one of the biggest weather-related killers i

Growing human antibodies in algae

Inexpensive and fast route to large-scale production, say scientists at The Scripps Research Institute

A group of scientists at The Scripps Research Institute (TSRI) have used algae to express an antibody that targets herpes virus, describing the work in an upcoming issue of the journal Proceedings of the National Academy of Sciences.

This antibody could potentially be an ingredient in an anti-herpes topical cream or other anti-herpes treatments, but more importantly the alg

Herpes virus trashes detection mechanism to hide from immune system

Herpes viruses are notorious for their ability to hide from the immune system and establish lifelong infections. Researchers at Washington University School of Medicine in St. Louis have discovered how one mouse herpes virus escapes detection. The study appears in the January issue of the journal Immunity.

“These findings not only provide a better understanding of viral infections,” says study leader Ted H. Hansen, Ph.D., professor of genetics, “they also offer novel insights into basic cel

UMass study reconsiders formation of Antarctic ice sheet

Findings detailed in Jan. 16 issue of Nature; greenhouse gases implicated

A study by University of Massachusetts Amherst geoscientist Robert DeConto posits an alternative theory regarding why Antarctica suddenly became glaciated 34 million years ago. The study challenges previous thinking about why the ice sheet formed and holds ramifications for the next several hundred years as greenhouse gases continue to rise. DeConto, who collaborated with David Pollard of Pennsylvania State Univ

A bright idea: Roadside beacons warn motorists of danger ahead

Fog-related pileups such as last month’s 71-car collision in Texas could become a thing of the past with roadside “smart beacons” that use the latest wireless technology to sense wrecks and warn motorists of danger ahead.

So say three University of Florida engineering researchers who this month applied for a patent on the concept for the beacons, which would be placed at regular intervals on roadside rights of way and would flash red or yellow lights to indicate a hazard ahead.

Isolated Star-Forming Cloud Discovered in Intracluster Space

Subaru and VLT Join Forces in New Study of Virgo Galaxy Cluster

At a distance of some 50 million light-years, the Virgo Cluster is the nearest galaxy cluster. It is located in the zodiacal constellation of the same name (The Virgin) and is a large and dense assembly of hundreds of galaxies.

The “intracluster” space between the Virgo galaxies is permeated by hot X-ray emitting gas and, as has become clear recently, by a sparse “intracluster population of stars”.
