Prenatal whole genome sequencing: Just because we can, should we? (August 10, 2012) -- With whole genome sequencing quickly becoming more affordable and accessible, we need to pay more attention to the massive amount of information it will deliver to parents -- and the fact that we don't yet understand what most of it means, concludes a new article. ... > full story

Of mice and melodies: Research on language gene seeks to uncover the origins of the singing mouse (August 10, 2012) -- Singing mice are unique rodents that use song to communicate. An important underlying gene that is thought to influence the singing behavior is a transcription factor called FOXP2, sometimes called the 'language gene' because it has been linked to speech disorders in humans. This information could help researchers find areas of the human FOXP2 gene that are associated with autism. ... > full story

Research shows gene defect's role in autism-like behavior (August 10, 2012) -- Scientists have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition. ... > full story

Daily aspirin usage linked to lower cancer mortality (August 10, 2012) -- A new study provides additional support for a potential benefit of daily aspirin use for cancer mortality, but the authors say important questions remain about the size of the potential benefit. ... > full story

NASA Curiosity Mars rover installing smarts for driving (August 10, 2012) -- NASA's Mars rover Curiosity will spend its first weekend on Mars transitioning to software better suited for tasks ahead, such as driving and using its strong robotic arm. The rover's "brain transplant," which will occur during a series of steps Aug. 10 through Aug. 13, will install a new version of software on both of the rover's redundant main computers. This software for Mars surface operations was uploaded to the rover's memory during the Mars Science Laboratory spacecraft's flight from Earth. ... > full story

Quantum cryptography theory has a demonstrated security defect (August 10, 2012) -- Researchers have just demonstrated the incompleteness and limit of the security theory in quantum key distribution. The present theory cannot guarantee unconditional security. ... > full story

Influence of heating techniques on red palm oil carotene levels (August 10, 2012) -- Researchers have studied carotene and antibacterial effects of microwave heated and conventional heated red palm oil (RPO). They discovered that conventional heating reduced its carotene levels but microwave heating retained a higher carotene content. ... > full story

Study of fruit fly chromosomes improves understanding of evolution and fertility (August 10, 2012) -- New research explores the evolution of sperm structure and function, through an analysis of Drosophila genes and gene products. The research has important implications for the study of human infertility as well. ... > full story

USDA: Ongoing drought causes significant crop yield declines (August 10, 2012) -- Corn production will drop 13 percent to a six-year low, the U.S. Agriculture Department said Aug. 10, confirming what many farmers already knew -- they are having a very bad year. ... > full story

NOAA raises hurricane season prediction despite expected El Niño (August 10, 2012) -- This year's Atlantic hurricane season got off to a busy start, with 6 named storms to date, and may have a busy second half, according to the updated hurricane season outlook issued Aug. 9, 2012 by NOAA's Climate Prediction Center, a division of the National Weather Service. The updated outlook still indicates a 50 percent chance of a near-normal season, but increases the chance of an above-normal season to 35 percent and decreases the chance of a below-normal season to only 15 percent from the initial outlook issued in May. ... > full story

50-year decline found in some Los Angeles vehicle-related pollutants (August 10, 2012) -- In California's Los Angeles Basin, levels of some vehicle-related air pollutants have decreased by about 98 percent since the 1960s, even as area residents now burn three times as much gasoline and diesel fuel. Between 2002 and 2010 alone, the concentration of air pollutants called volatile organic compounds (VOCs) dropped by half, according to a new study by NOAA scientists and colleagues. ... > full story

New view of body's infection response (August 10, 2012) -- A new 3-D view of the body's response to infection – and the ability to identify proteins involved in the response – could point to novel biomarkers and therapeutic agents for infectious diseases. Scientists in multiple disciplines combined magnetic resonance imaging and imaging mass spectrometry to visualize the inflammatory response to bacterial infection in mice. The techniques offer opportunities for discovering proteins not previously implicated in the inflammatory response. ... > full story
