HealthDay News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Most people have met some 65-year-olds who aren't as "with it" as they once were, and some 90-year-olds who are still sharp as a whip. What accounts for the differences? Using a genetic analysis and intelligence tests taken by a group of people in childhood and old age, researchers concluded both genes and environmental factors play a role in whether you'll maintain your level of intelligence throughout your lifespan.

Slideshow: Famous photographers pose with their most iconic images
Wired    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The Tank Man of Tienanmen Square. Muhammad Ali standing over Sonny Liston in victory. The portrait of the Afghan Girl on the cover of National Geographic. Many of us can automatically recall these photos in our heads, but far fewer can name the photographers who took them. Even fewer know what those photographers look like. Tim Mantoani hopes to change that by taking portraits of famous photographers holding their most iconic or favorite photos. More

Male bowerbirds may use optical illusion to woo mates
Wired    Share    Share on FacebookTwitterShare on LinkedinE-mail article
It takes some trickery for a male great bowerbird (Ptilonorhynchus nuchalis) to hold a female's attention. He spends a majority of his time building and performing upkeep on an intricate structure called a bower to attract members of the opposite sex. Two stick walls arch over the east and west sides of the bower, and a courtyard filled with trinkets — such as rocks, sticks, shells and bones — stretches from south to north. More

Teardrops' proteins chomp bacteria like corn on the cob
Live Science    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Teardrops hold more than painful tales: Disease-fighting proteins also hide out in them. Long puzzled by the specifics of how the proteins in these weepy droplets destroy dangerous bacteria, scientists have finally figured out their secret: The proteins, known as lysozymes, have jawlike structures that latch onto bacterial cell walls and chomp through rows of them as if devouring an ear of corn.

Toward twister forecasting: Scientists make progress in assessing tornado seasons
ScienceDaily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Meteorologists can see a busy hurricane season brewing months ahead, but until now there has been no such crystal ball for tornadoes, which are much smaller and more volatile. This information gap took on new urgency after tornadoes in 2011 killed more than 550 people, more than in the previous 10 years combined, including a devastating outbreak in April that racked up $5 billion in insured losses. Now, a new study of short-term climate trends offers the first framework for predicting tornado activity up to a month out with current technology and possibly further out as climate models improve, giving communities a chance to plan.

Study: Babies lip-read before talking
ScienceNews    Share    Share on FacebookTwitterShare on LinkedinE-mail article
When adults mouth off, babies learn by watching. As infants start babbling at around age 6 months in preparation for talking, they shift from focusing on adults' eyes to paying special attention to speakers' mouths, a new study finds. As tots become able to blurt out words and simple statements at age 1, they go back to concentrating on adults' eyes, say psychologist David Lewkowicz and psychology graduate student Amy Hansen-Tift, both of Florida Atlantic University in Boca Raton.
