It's not often that we get to see strange underwater creatures in action in their natural habitat. But thanks to the many advances in digital technology, we are given this rare look at a mysterious benthopelagic sea animal: Grimpoteuthis bathynectes, one in a group of 14 recognised species that are often referred to as "Dumbo octopus" because their fins resemble the large ears that the fictional character, Dumbo the elephant, used to fly. In this astonishing video, filmed 200 miles east of the coast of Oregon state, we can observe how this ghostly-white octopus moves through the inky-blackness of the deep sea:
Yea - score another one for basic research!

New type of insect repellant may be thousands of times stronger than DEET
May 9, 2011
Imagine an insect repellant that not only is thousands of times more effective than DEET – the active ingredient in most commercial mosquito repellants – but also works against all types of insects, including flies, moths and ants.
That possibility has been created by the discovery of a new class of insect repellant made in the laboratory of Vanderbilt Professor of Biological Sciences and Pharmacology Laurence Zwiebel and reported this week in the online Early Edition of the Proceedings of the National Academy of Sciences.
The discovery of this new class of repellant is based on insights that scientists have gained about the basic nature of the insect's sense of smell in the last few years.

How to tell when someone's lying

See article for list!The ability to effectively detect deception is crucial to public safety, particularly in the wake of renewed threats against the U.S. following the killing of Osama bin Laden.
UCLA professor of psychology R. Edward Geiselman has been studying these questions for years and has taught investigative interviewing techniques to detectives and intelligence officers from the FBI, the Department of Homeland Security, the Marines, the Los Angeles police and sheriff's departments, and numerous international agencies.
He and three former UCLA undergraduates — Sandra Elmgren, Chris Green and Ida Rystad —analyzed some 60 studies on detecting deception and have conducted original research on the subject. They present their findings and their guidance for how to conduct effective training programs for detecting deception in the current (April) issue of the American Journal of Forensic Psychiatry, which is published this week.
Geiselman and his colleagues have identified several indicators that a person is being deceptive. The more reliable red flags that indicate deceit, Geiselman said, include:

Just FUN!
Why odd alien planets travel in backward orbits
Scientists find they arise when a giant world farther away from parent star interferes
"Scientists have a new explanation for the mystery of why some alien planets the size of Jupiter or larger travel in the opposite direction of their parent star's spin.
Of the more than 500 alien planets that have so far been discovered, many have turned out to be oddballs. Scientists have found planets with extremely elongated or highly tilted orbits, or planets that follow paths that swing in very close to their parent stars.
The cream of the weird planet crop are so-called hot Jupiters— large gas giant planets that circle extremely close to their stars — that seem to orbit around their stars in the opposite direction of their parent star's spin. About a quarter of all hot Jupiter planets discovered by astronomers seem to be these strange backward-traveling worlds."
