Gene Involved in Human Language Development Also Involved In Bat Echolocation

When it comes to the FOXP2 gene, humans have had most to shout about. Discoveries that mutations in this gene lead to speech defects and that the gene underwent changes around the time language evolved both implicate FOXP2 in the evolution of human language. A new study has found that the FOXP2 gene shows unparalleled variation in echolocating bats. This gene's sequence differences among bat...

Gene Mutation Thought To Control Energy Levels Discovered

Scientists have discovered a mutation in a gene that is widely considered to be the major controller of energy levels in our bodies. The discovery has significant implications for people suffering from diabetes and for endurance athletes. This study focused on the gene for AMPK (adenosine monophosphate-activated protein kinase), which controls the amount of energy in our cells by becoming active...

New Strategy Could Dramatically Slow The Spread Of HIV

Giving a daily antiretroviral pill to people could profoundly slow the spread of the infection in sub-Saharan Africa by potentially preventing 3.2 million cases of HIV in 10 years. The findings are based on a mathematical model developed to predict the public-health impact of pre-exposure chemoprophylaxis -- an HIV prevention strategy that uses antiretroviral drugs to stop the infection from...

Hygiene Habits Stall: Public Handwashing Down

When it comes to washing with soap and water, some Americans seem be slipping up. In an observational study slightly over three-quarters of men and women (77 percent) washed their hands in public restrooms -- a six percent decline from a similar study conducted in 2005.

Shaking May Cause Brain Damage And Serious Long-term Effects To Infants

Researchers have carried out a bibliographic review of the shaken baby syndrome. Many of the diagnosed cases which produce internal damage to the infant have been caused by mistreatment or abuse. Crying is the only way a baby can express its feelings and needs. If the parents or caregivers cannot find the cause of the inconsolable crying of the infant, they might react sharply and shake the baby....

Subprime problems signal trouble ahead, research shows

If it seems as though sub-prime mortgage loans stirred up trouble in the financial markets, just wait until debt problems spill over onto household spending. According to economists Barry Cynamon and Steven Fazzari, America's love affair with consumption has been a big source of economic stimulus for a long time. But the party might be about to end. Americans' overextended wallets could trigger...

New Bose Speakers Are Even Smaller

(AP) -- Bose Corp. introduced new $399 speakers on Tuesday designed to provide top-quality sound from a desktop and capitalize on the emergence of the computer as a home music center.

Bone-growing Nanomaterial Could Improve Orthopaedic Implants

Bone-forming cells grow faster and produce more calcium on anodized titanium covered in carbon nanotubes compared with plain anodized titanium and the non-anodized version currently used in orthopaedic implants, new research shows. The work, published in Nanotechnology, uncovers a new material that can be used to make more successful implants. The research also shows tantalizing promise for an...
