The most comprehensive analysis to date of research on the effect of negative stereotypes on older people's abilities has concluded that these stereotypes create a significant problem for that demographic.

A research team at the University of Kent's School of Psychology carried out a review and meta-analysis of Aged-Based Stereotype Threat (ABST).

They statistically analyzed international evidence from 37 research studies, both published and unpublished. They concluded that older adults' memory and cognitive performance is negatively affected in situations that signal or remind them of negative age stereotypes. These effects affect both men and women.

fter 200 million gallons of crude oil spilled into the Gulf of Mexico in April 2010, the government and BP cleanup crews mysteriously had trouble locating all of it.

Now, a new study led by Florida State University Professor of Oceanography Jeff Chanton finds that some 6 million to 10 million gallons are buried in the sediment on the Gulf floor, about 62 miles southeast of the Mississippi Delta.

"This is going to affect the Gulf for years to come," Chanton said. "Fish will likely ingest contaminants because worms ingest the sediment, and fish eat the worms. It's a conduit for contamination into the food web."

When donating blood, plasma, human tissue or any other bodily sample for medical research, most people might not think about how it's being used. But if you were told, would you care?

A new Michigan State University study, published in the Journal of the American Medical Association, indicates that most people are willing to donate just knowing that their contribution is going toward research. But, when specific scenarios are brought into the equation, that willingness changes.

Many co-products from the corn processing industry may be used in diets fed to pigs. Much attention over the last 10 years has been on co-products produced from the biofuels industry, including distillers dried grains and high-protein distillers grains. However, the wet milling industry also produces many different co-products that may be used in pig diets.

Because little information about co-products produced from the wet milling industry has been reported, research from the University of Illinois is helping to determine the nutritional value of four of these co-products so that producers and companies can incorporate these ingredients into swine diets, said Hans H. Stein, a U of I animal science researcher.

It's no surprise that pain shows up in brain scans but a new study finds distinct, consistent patterns of brain activity in response to needles used in vaccinations.

The researchers performed elecroencephalography (EEG) in 15 healthy babies receiving routine vaccinations. A noninvasive and painless procedure, EEG is done to measure electrical activity in the brain, using electrodes placed in specific locations on the scalp.

12 infants were tested during vaccinations at age one to two months, and five at age 12 months.

Bitcoin is the digital world's most popular "virtual currency", with millions in circulation. Fraudulent schemes have scammed at least $11 million in these virtual deposits from customers over the past four years, according to new cyber-security research from Southern Methodist University.

In the first empirical study of its kind, the authors found that four different types of schemes using authentic-looking web-based investment and banking outlets lured customers so deposits could be stolen.

As with real money, Bitcoin people were duped with the promise of "get rich quick" schemes, coupled with the inability to judge the legitimacy of web services to decide which financial sites are good or bad.
