• 20:00 Diet Secrets Of Elephant Family Named 'The Royals'

  Read the story at ScienceDaily
  Two weeks after rains begin, an elephant family named "the Royals" usually switches to a grass diet to bulk up for pregnancy. But when they wandered off their African reserve, cattle grazed the grass so short that elephants couldn't eat it. The new study -- which suggests how climate change and human encroachment may affect endangered elephants -- used tracking collars and analyzed isotopes in tail hair to monitor the elephants' movements and diet.

• 20:00 X Marks The Spot: Ions Coldly Go Through NIST Trap Junction

  Read the story at ScienceDaily
  Physicists have demonstrated a new ion trap that enables ions to go through an intersection at temperatures ten million times cooler than prior similar trips. The demonstration is a step toward scaling up trap technology to build a large-scale quantum computer using ions.

  Read the story at ScienceDaily
  Researchers have found that delayed-enhancement magnetic resonance imaging holds promise for predicting treatment outcomes and measuring disease progression for patients with atrial fibrillation (AF), a little known heart rhythm disorder that affects more than 3.5 million Americans and causes more than 66,000 deaths a year.

• 20:00 Male Circumcision Reduces HIV Risk: No Further Evidence Needed, According To Review

  Read the story at ScienceDaily
  Three recent African trials support male circumcision for reducing the risk of contracting HIV in heterosexual men. After including new data from these trials in their review, researchers have changed their previous conclusions that there was insufficient evidence to recommend circumcision as an intervention to prevent HIV infection in heterosexual men.

• 20:00 Rare Window On Spinal Muscular Atrophy Genetics

  Read the story at ScienceDaily
  Caused by a mutation of the SMN gene, spinal muscular atrophy is an infantile and juvenile neurodegenerative disorder where motor neuron loss causes progressive paralysis. A new study details the first research focused on human muscle tissue atrophied due to a genetic condition, and sheds light on two distinct mechanisms at work in different forms of SMA.

• 06:00 'Free Play' For Children, Teens Is Vital To Social Development, Reports Psychologist

  Read the story at ScienceDaily
  A new theory about early human adaptation suggests that use of "free" self-organized play for children, teens and even among adults is a key element in the development of cooperative social skills. Psychologists suggest that the self-centered actions that led to the current economic collapse may, in part, be symptoms of a society that has replaced what used to be known as "play" with more competitive activities that require a drive to win.

• 06:00 'Two-handed' Marine Microbes Point To New Method For Isolating Harmful Forms Of Chemicals

  Read the story at ScienceDaily
  Scientists studying how marine bacteria move have discovered that a sharp variation in water current segregates right-handed bacteria from their left-handed brethren, impelling the microbes in opposite directions.

• 06:00 Birds: Feather Color Is More Than Skin Deep

  Read the story at ScienceDaily
  Where do birds get their red feathers from? According to a new article, the red carotenoids that give the common crossbill (Loxia curvirostra) its red coloration are produced in the liver, not the skin, as previously thought. Their findings have implications for understanding the evolution of color signaling in bird species.

• 06:00 HIV De-arms Protective Protein In Cells

  Read the story at ScienceDaily
  The AIDS-causing HIV specifically counteracts the mechanisms of human cells that protect these against viral infections -- a special viral protein marks protective cellular proteins for their rapid destruction and thus diminishes the cell's supply. Researchers demonstrated this mechanism for the first time in cell cultures, thus discovering a target for a novel treatment strategy.

• 06:00 HIV Handicaps Itself To Escape Immune System Pressure

  Read the story at ScienceDaily
  HIV quickly mutates and evolves in response to pressure from the immune system. A set of three mutations that conceal HIV from particularly strong human immune systems slow viral replication considerably. However, once all three mutations are in place, the virus becomes "invisible" to the immune system and its abundance shoots upwards. The results demonstrate the importance of "killer" T cell immune responses in controlling HIV and shows that vaccines will need to stimulate responses against several parts of the virus.

• 06:00 Liver Disease: It Is Never Too Late To Stop Drinking, According To Researchers

  Read the story at ScienceDaily
  Where there is life there is hope and it is never too late to stop drinking, even with the most severe case of alcohol-related liver disease, according to new research. However, the downside is that up a quarter of people with alcohol-related cirrhosis die before they get the chance to stop drinking. Alcohol-related cirrhosis develops silently but usually presents with an episode of internal bleeding or jaundice - which is often fatal.

• 06:00 Long-lasting Nerve Block Could Change Pain Management

  Read the story at ScienceDaily
  Medical researchers have developed a slow-release local anesthetic that could potentially revolutionize treatment of pain during and after surgery. By encapsulating anesthetics in fatty particles and injecting them into rats, they created a long-lasting nerve block that blocked pain without being toxic to nerves or muscles. The research could also have a large impact on chronic pain management, avoiding the need for systemic narcotics.

• 06:00 Midwestern Ethanol Industrial Processes Use Much Less Water Than That Used In Western Plants

  Read the story at ScienceDaily
  Ethanol production in Minnesota and Iowa uses far less water overall than similar processes in states where water is less plentiful, a new study shows. Iowa uses 6 gallons of water to make one gallon of ethanol -- California uses 2,100 gallons.

• 06:00 Mild Dementia Detected In Humans Through Eye Tracking

  Read the story at ScienceDaily
  Researchers developed a test in nonhuman primates that is now using infrared eye tracking to detect mild cognitive impairment in humans. The researchers hope the advanced technology will be helpful in predicting the onset of Alzheimer's disease. The test is helping researchers further understand the role of the brain structures critical to human memory.

  Read the story at ScienceDaily
  Bone-marrow-derived liver stem cells were once a hot topic in the field of stem cell research because of their important therapeutic implications, but little progress has been made in recent years because of the difficulty of isolation and proliferation of this special cell population. A research group in China has provided a new method for BDLSC isolation and proliferation, which brings new hope to the clinical use of bone-marrow-derived stem cells.

• 06:00 New Way To Analyze Sleep Disorders

  Read the story at ScienceDaily
  Sleep is such an essential part of human existence that we spend about a third of our lives doing it -- some more successfully than others. Sleep disorders afflict some 50-70 million people in the United States and are a major cause of disease and injury. People who suffer from disturbed sleep have an increased risk of heart attack, stroke, hypertension, obesity, depression, and accidents. Nearly a fifth of all serious car crashes, in fact, are linked to sleeplessness.
