Geologists find meteorites 100 times more common in wake of ancient asteroid collision

Using fossil meteorites and ancient limestone unearthed throughout southern Sweden, marine geologists at Rice University have discovered that a colossal collision in the asteroid belt some 500 million years ago led to intense meteorite strikes over the Earth’s surface.

The research, which appears in this week’s issue of Science magazine, is based upon an analysis of fossil meteor

In photographs, it looks like a big red spaceship cruising the ocean depths. But it’s actually a new species of jelly that was discovered and described by scientists at the Monterey Bay Aquarium Research Institute. MBARI scientists published their research on this unusual animal in a recent online version of the journal Marine Biology.

With a bell diameter of up to a meter wide, the new jelly, named Tiburonia granrojo or “big red,” would seem tough to miss, except that it lives deep below t

Children who frequently change schools are more likely than those who don’t to have behavioral health problems, according to a new Cincinnati Children’s Hospital Medical Center study.

The study, to be presented Sunday, May 4, at the annual meeting of the Pediatric Academic Societies in Seattle, shows that school mobility is an independent predictor of behavioral problems – regardless of one’s race, income, maternal education level or any other factor measured in the study.

Computer security researchers suggest ways to thwart new form of cybercrime

Most experts on computer crime focus on attacks against Web servers, bank account tampering and other mischief confined to the digital world. But by using little more than a Web search engine and some simple software, a computer-savvy criminal or terrorist could easily leap beyond the boundaries of cyberspace to wreak havoc in the physical world, a team of Internet security researchers has concluded.

Pioneering research carried out by Kingston University is helping to pave the way for a manned mission to Mars. A project team based at the University’s School of Engineering has developed a robotic micro-rover to travel the Martian surface to find out whether humans could live in the Red Planet’s hostile environment.

Named Endurance, the small self-propelled vehicle will be powered by the sun’s rays and equipped to drill beneath the surface to find out if life exists on Mars in the form of

Several industrial activities of the previous decades resulted in serious contamination of groundwater. For instance, polyvinyl chloride (PVC) production and related activities cause annual underground releases of 137 tonnes of 1,2-dichloroethane (1,2-DCA) in the USA (1988-1999). The latter molecule has an environmental half-life of about 50 years, is the most abundant groundwater pollutant of all chloroethenes and –ethanes, and is a suspected carcinogen. Its physico-chemical properties result in a s
