Researchers know that animals which seem identical can actually belong to completely different species. But if it's worms used in laboratory testing, that could be important news in research.
Researchers at the University of Gothenburg, Sweden, say they have used DNA analyses to discover that one of our most common segmented worms, Lumbriculus variegatus, is actually two types of worm. Along with some obvious issues in research it also affirms that the variety of species on the earth could be considerably larger than we thought. "We could be talking about a large number of species that have existed undiscovered because they resemble other known species," says Professor Christer Erséus.
WHAT: New research from Baylor College of Medicine indicates a positive effect of chewing gum on academic performance in teenagers. The study examined whether chewing Wrigley sugar-free gum can lead to better academic performance in a "real life" classroom setting. Major findings include:
- The researchers found that students who chewed gum showed an increase in standardized math test scores and their final grades were better compared to those who didn't chew gum.
A new study reveals that asteroid surfaces age and redden much faster than previously thought — in less than a million years, the blink of an eye for an asteroid. The solar wind is the likely culprit in very rapid space weathering, they say, and this knowledge will help astronomers relate the appearance of an asteroid to its actual history and identify any after effects of a catastrophic impact with another asteroid.
Waves from Daphnis
Undulations mark both sides of the path of Saturn's moon Daphnis through the A ring.
Daphnis may be small at only 8 kilometers (5 miles) across, but the moon's gravity is great enough, and the Keeler gap in which it resides is narrow enough, so that the perturbed particles create the wavelike patterns seen here.
Utah and Texas researchers have learned how quiet sounds are magnified by bundles of tiny, hair-like tubes atop “hair cells” in the ear: when the tubes dance back and forth, they act as “flexoelectric motors” that amplify sound mechanically.
“We are reporting discovery of a new nanoscale motor in the ear,” says Richard Rabbitt, the study’s principal author and a professor and chair of bioengineering at the University of Utah College of Engineering. “The ear has a mechanical amplifier in it that uses electrical power to do mechanical amplification.”

The UK Advertising Standards Authority (ASA) today ruled that Pfizer's groundbreaking cinema advertising in which a man is seen coughing-up a dead rat did not breach the industry advertising code.(1)
The advert, seen by cinema audiences across the UK, highlights the danger of obtaining medicines from unregulated sources (see http://www.realdanger.co.uk). Evidence shows there is a risk of these medicines being counterfeit, containing too little, too much or no active ingredient, or worse, toxic substances such as rat poison, boric acid or lead paint.(4)

For those of us who are savvy on health food, what I’m about to tell you will come as no surprise, if not, hold onto your hats. If you have heard about “good fats” such as poly-unsaturated fats and omega fatty acids, found in fish and olive oil, then you know that researchers and nutrition professionals agree that these fats should replace the “bad fats” including trans fats and saturated fats found in junk food.
The body does need some fats, and the “good fats” in olive oil and fish are much more easily broken down and utilized by the body instead of the saturated fats, which instead of being broken down, may be allocated to fat storage, and add inches to the waistline and pounds to your physique.
