The study is published in Child Development in the journal's January/February 2010 issue. To learn how the deprivation and neglect that institutionalized children often experience affect brain development, the researchers...

The new study reported on 40 people who were treated with botulinum toxin, or Botox. Tiny applications of this powerful nerve poison were used to deactivate...

Despite warnings over loud rock music damaging their ears, the baby boomer generation appears to have better hearing than their parents did. A new study suggests that the rate of hearing problems at ages 45 to 75 has been dropping for years, at least among white Americans. "I'm less likely to have a hearing loss when I get to be 70 years old than my grandmother did when she was 70," Karen Cruickshanks of the University of Wisconsin-Madison, told the Associated Press. Cruickshanks, the...

EAU CLAIRE, Wis., Jan. 25 /PRNewswire/ -- A little goes a long way when it comes to companies talking about their products in advertisements aired during the Super Bowl, say University of Wisconsin-Eau Claire marketing professors who have studied Super Bowl advertising for a decade. "More is definitely less," said Dr. Rama Yelkur, a lead researcher on the project, which she believes is the most comprehensive Super Bowl advertising study to date. "If you want to have a popular Super Bowl...

While much of the promise of stem cells springs from their ability to develop into any cell type in the body, the biological workings that control that maturation process are still largely unknown. Writing in the online edition of the Proceedings of the National Academy of Sciences this week (Jan. 11), scientists from the University of Wisconsin-Madison and the University of California-Irvine present a new model of stem cell regulation. Working with the small roundworm Caenorhabditis elegans,...

Conservationists have long known that lines on a map are not sufficient to protect nature because what happens outside those boundaries can affect what happens within. Now, a study by two University of Wisconsin-Madison scientists in the department of forest and wildlife ecology measures the threat of housing development around protected areas in the United States. In a study published this week in the Proceedings of the National Academy of Sciences (PNAS), Volker Radeloff, an associate...

For almost 50 years, astronomers have puzzled over the youthful appearance of stars known as blue stragglers. Blue stragglers are the timeworn Hollywood starlets of the cosmos: They shine brightly, they are older than they appear, and they have, disconcertingly, gained mass at a late stage of life. "These blue, luminous stars should have used up their hydrogen fuel and flamed out long ago," explains Robert Mathieu, a University of Wisconsin-Madison astronomer. "Yet they are still here. By...

Some of the most common minerals in biology, including those in bones and shells, have a mysterious structure: Their crystals are positioned in the same orientation, making them behave as one giant crystal, even though they do not look like a faceted crystal. It's as if grains of salt were spilled on a rug, yet instead of landing randomly, all wound up with exactly the same angle and rotation. In a new study in the Journal of the American Chemical Society, Pupa Gilbert, a professor of physics...

A new study at the University of Wisconsin-Madison suggests that depressed patients are unable to sustain activity in brain areas related to positive emotion. The study challenges previous notions that individuals with depression show less brain activity in areas associated with positive emotion. Instead, the new data suggest similar initial levels of activity, but an inability to sustain them over time. The new work was reported online this week (Dec. 21) in the Proceedings of the National...
