Saturn propellers reflect solar system origins (July 10, 2010) -- Scientists using NASA's Cassini spacecraft at Saturn have stalked a new class of moons in the rings of Saturn that create distinctive propeller-shaped gaps in ring material. It marks the first time scientists have been able to track the orbits of individual objects in a debris disk. The research gives scientists an opportunity to time-travel back into the history of our solar system to reveal clues about disks around other stars in our universe that are too far away to observe directly. ... > full story

Antibody may help treat and prevent influenza outbreaks (July 10, 2010) -- Researchers have discovered a monoclonal antibody that is effective against "avian" H5N1, seasonal H1N1 and the 2009 "swine" H1N1 influenza. Scientists have shown that this antibody potently prevents and treats the swine H1N1 influenza in mouse models of the disease. ... > full story

Better barriers can help levees withstand wave erosion (July 10, 2010) -- A new barrier design could protect reservoir levees from the erosive forces of wind-driven waves, according new research. These findings could help lower the maintenance costs for constructed ponds in the lower Mississippi Delta where levee repairs can average per foot -- and sometimes are needed just five years after a reservoir is built. ... > full story

Protein that predicts prognosis of leukemia patients may also be a therapeutic target (July 10, 2010) -- Researchers at Whitehead Institute and Children's Hospital Boston have identified a protein, called Musashi 2, that is predictive of prognosis in acute myeloid leukemia and chronic myeloid leukemia patients. Diagnosed in an estimated 48,000 new patients annually, leukemia is blood cancer characterized by an overgrowth of certain blood cells. Musashi 2 and the cellular functions it affects could potentially represent therapeutic targets in certain types of leukemia. ... > full story

Novel ion trap with optical fiber could link atoms and light in quantum networks (July 10, 2010) -- Physicists have demonstrated an ion trap with a built-in optical fiber that collects light emitted by single ions, allowing quantum information stored in the ions to be measured. The advance could simplify quantum computer design and serve as a step toward swapping information between matter and light in future quantum networks. ... > full story

Moms' favoritism tied to depression in adulthood (July 10, 2010) -- Whether mom's golden child or her black sheep, siblings who sense that their mother consistently favors or rejects one child over others are more likely to show depressive symptoms as middle-aged adults, finds a new study. ... > full story

Researchers use robot to determine how human strangers develop trust (July 10, 2010) -- What can a wide-eyed, talking robot teach us about trust? A lot, according to psychology professors who are conducting innovative research to determine how humans decide to trust strangers -- and if those decisions are accurate. ... > full story

Honey bee venom may help design new treatments to alleviate muscular dystrophy, depression and dementia (July 10, 2010) -- Scientists researching a toxin extracted from the venom of the honey bee have used this to inform the design of new treatments to alleviate the symptoms of conditions such as muscular dystrophy, depression and dementia. ... > full story

New spin on drug delivery: Chemical engineers discover an enhanced delivery method of DNA payloads into cells (July 10, 2010) -- Chemical engineers have discovered how to "greatly enhance" the delivery of DNA payloads into cells. Lu's ultimate goal is to apply this technique to create genetically modified cells for cancer immunotherapy, stem cell therapy and tissue regeneration. ... > full story

Severe angina poses three times the coronary artery disease risk for women than men (July 10, 2010) -- Women who have the most serious form of angina are three times as likely to develop severe coronary artery disease (CAD) as men with the same condition, according to a new study. ... > full story

Rain of giant gas clouds create active galactic nuclei: New research explains how galaxy centers light up (July 10, 2010) -- Galaxies like our own were built billions of years ago from a deluge of giant clouds of gas, some of which continue to rain down. Now new calculations tie the rain of giant clouds of gas to active galactic nuclei, the extremely bright centers of some galaxies. ... > full story

Homicide and suicide rates among mentally ill on the decline, UK study finds (July 10, 2010) -- People with mental health problems are committing fewer homicides while the number of suicides by mental health patients has also fallen, latest figures reveal; a previous rise in homicides by mentally ill people may have been the result of drug misuse, says the report. ... > full story
