Computer experts at the University of Southampton have just released a new version of their hugely popular free-to-use email security system MailScanner, offering a high level of protection to companies and institutions wanting to safeguard their computer networks from viruses and the potential threat of cyberterrorism.

Developed by Julian Field of the University of Southampton’s world-renowned Department of Electronics and Computer Science, MailScanner processes over 500 million email mes

Binghamton University electronics engineering center charts new directions at ’micro’ and ’nano’ scale

Imagine a diagnostic “pill” that doctors can navigate through your system to collect video and chemical data about what’s going on in your body. Or how about a space age, two-ply, self-assembling organic-inorganic thin film that makes expensive mirrors and lenses such as those used by NASA virtually indestructible.

Each of these items is at the hear

To study the genetic components of disease, researchers rely on mice or other research models in which particular genes are silenced, or turned off. In recent years, researchers discovered that they can selectively silence genes using small pieces of RNA called siRNA (short interfering RNA).

Unfortunately, sorting out which siRNA sequences block expression of which genes has proven to be truly daunting. Researchers at Whitehead Institute, however, recently released for public use a new comp

Hormones and neurotransmitters secreted from cells via bubble-like vesicles are released using age-related criteria, with the youngest vesicles getting first shot at releasing their contents, according to research led by a University of Southern California (USC) physiologist. This is a “complete reverse” from what had previously been presumed to be the process behind hormone secretion, notes Robert Chow, M.D., Ph.D., associate professor of

In a major breakthrough for understanding what one of them calls “the most exotic environment in the Universe,” a team of astronomers has discovered that powerful radio bursts in pulsars are generated by structures as small as a beach ball.

“These are by far the smallest objects ever detected outside our solar system,” said Tim Hankins, leader of the research team, which studied the pulsar at the center of the Crab Nebula, more than 6,000 light-years from Earth. “The small size of these regi

When were the mountains of Wales pushed up?

It was well before the dinosaurs roamed the earth. And it happened in the aftermath of a gigantic continental collision, when England and Wales (then attached to southern Newfoundland) crashed into Scotland (then attached to north America). The muds of the sea floor were converted, then, into the hard grey slates of the Welsh hills.

Until now it has been very hard to tell exactly when these slates were formed, because the miner
