The Facts About Earthquakes and Tsunamis

Earthquake and Tsunami

It’s possible to run from a tornado. Hurricanes normally have a lot of warning that precedes them before they hit land. Ice, heat, and other environmental challenges can be dealt with. Earthquakes and tsunamis, on the other hand, can devastate without warning.

Most Exciting Forensic Science Jobs

CSI

Do you fantasize about growing up to become the real version of CSI’s crime-solving forensic scientist, but aren’t sure if the job is really as exciting as it seems on TV? Although you’re right to be skeptical (and many of the law enforcement processes depicted on fictional crime shows are inaccurate or flawed), forensic science is truly an exciting field to work in. Sure, there are boring branches of forensic science like odontology, which takes a bite out of crime by studying teeth.

Making Fire… with Ice

Fire from Ice

There are forces at work in science that often amaze us with their polarizations and the oxymorons that are created. They aren’t necessarily contradictions, but rather conforming aspects within the apparent opposites.

Such is the case with making fire from ice. It’s simple, really, but cool nonetheless. Continue reading Making Fire… with Ice

New Artificial “Skin” Can Sense Pressure

New artificial “skin” fashioned out of flexible semiconductor materials can sense touch, making it possible to create robots with a grip delicate enough to hold an egg, yet strong enough to grasp the frying pan, U.S. researchers said on Sunday.

Scientists have long struggled with a way to make robotic devices capable of adjusting the amount of force needed to hold and use different objects. The pressure-sensitive materials are designed to overcome that challenge.

“Humans generally know how to hold a fragile egg without breaking it,” said Ali Javey, an electrical engineer at the University of California Berkeley, who led one of two teams reporting on artificial skin discoveries in the journal Nature Materials.

“If we ever wanted a robot that could unload the dishes, for instance, we’d want to make sure it doesn’t break the wine glasses in the process. But we’d also want the robot to be able to grip a stock pot without dropping it,” Javey said in a statement.

Javey’s team found a way to make ultra tiny “nanowires” from an alloy of silicon and germanium. Wires of this material were formed on the outside of a cylindrical drum, which was then rolled onto a sticky film, depositing the wires in a uniform pattern.

Research Shows: Risk of Marijuana’s ‘gateway effect’ Overblown

New research from the University of New Hampshire shows that the “gateway effect” of marijuana – that teenagers who use marijuana are more likely to move on to harder illicit drugs as young adults – is overblown.

Whether teenagers who smoked pot will use other illicit drugs as young adults has more to do with life factors such as employment status and stress, according to the new research. In fact, the strongest predictor of whether someone will use other illicit drugs is their race/ethnicity, not whether they ever used marijuana.

Conducted by UNH associate professors of sociology Karen Van Gundy and Cesar Rebellon, the research appears in the September 2010, issue of the Journal of Health and Social Behavior in the article, “A Life-course Perspective on the ‘Gateway Hypothesis.’ “

“In light of these findings, we urge U.S. drug control policymakers to consider stress and life-course approaches in their pursuit of solutions to the ‘drug problem,’ ” Van Gundy and Rebellon say.

The researchers used survey data from 1,286 young adults who attended Miami-Dade public schools in the 1990s. Within the final sample, 26 percent of the respondents are African American, 44 percent are Hispanic, and 30 percent are non-Hispanic white.
