Bats use blood to reshape tongue for feeding

Posted: 06 May 2013 02:45 PM PDT

Brown University scientists have found that a species of bat uses blood flow to reshape its tongue while feeding. The quick dynamic action makes the tongue an effective “mop” for nectar and could even inspire new industrial designs. Findings are reported in the Proceedings of the National Academy of Sciences.

Traumatized moms avoid tough talks with kids, study shows

Mothers who have experienced childhood abuse, neglect or other traumatic experiences show an unwillingness to talk with their children about the child’s emotional experiences, a new study from the University of Notre Dame shows.

Wider definition of ADHD could benefit more people with symptoms

Getting diagnosed and treated for attention deficient/hyperactivity disorder (ADHD) is about to get easier for the more than 13 million people who struggle with distractibility and other symptoms.

In May, changes to the Diagnostic and Statistical Manual of Mental Disorders will broaden the definition and diagnosis of ADHD, a disorder that affects an estimated 7 percent of school-aged children.

Studies of the assembly of a protein degradation machine could lead to treatments in cancer, neurological diseases

Kansas State University scientists helped discover new details about an intricate process in cells. Their finding may advance treatments for cancer and neurological diseases.

Discovery of endogenous antibiotic in the brain

Scientists from the Luxembourg Centre for Systems Biomedicine (LCSB) of the University of Luxembourg have discovered that immune cells in the brain can produce a substance that prevents bacterial growth: namely itaconic acid.

Researchers Reveal New More Precise Method of Performing Electroconvulsive Therapy (ECT)

Posted: 06 May 2013 07:56 AM PDT

Electroconvulsive therapy (ECT) is the most effective acute treatment for severe major depression. However, even with newer forms of ECT, there remains a significant risk of adverse cognitive effects, particularly memory problems.

Current theories hold that the regions that need to be stimulated to treat the depression (the cortex) are different and separate from the regions that result in memory problems (the hippocampus and temporal lobes). Theoretically, a more precise form of ECT could have all of the efficacy and few or none of the adverse cognitive side effects.

Do-It-Yourself Invisibility with 3-D Printing

Seven years ago, Duke University engineers demonstrated the first working invisibility cloak in complex laboratory experiments. Now it appears creating a simple cloak has become a lot simpler.

“I would argue that essentially anyone who can spend a couple thousand dollars on a non-industry grade 3-D printer can literally make a plastic cloak overnight,” said Yaroslav Urzhumov, assistant research professor in electrical and computer engineering at Duke’s Pratt School of Engineering.
