Finding ET
Research in the field of exobiology relies on one of the biggest assumptions we make about the universe - that we are not alone, that there could be life on worlds other than the Earth.However, one assumption we should not make about life elsewhere in the universe is that it uses the same templates and [...] Neurotransmitter Orexin Associated With Pleasure And Reward Pathways I
Researchers at the University of Pennsylvania School of Medicine have discovered that the recently identified neurotransmitter orexin (also known as hypocretin) influences reward processing by activating neurons in the lateral hypothalamus region of the brain. By identifying the relationship between orexin neurons and behaviors associated with reward seeking, drug relapse, and addiction, researchers hope to find new treatments for drug addiction. Ulysses Starts New Journey Around The Sun's Poles
Sixteen years after its launch on Oct. 6, 1990, the Ulysses spacecraft has begun its third "solar polar orbit"-- a journey around the poles of the sun. The mission, a joint NASA-European Space Agency venture, studies how the sun's gaseous outer atmosphere spews into space, creating huge space storms. This violent "space weather,"in turn, can affect Earth's electricity, satellite and cell phone communications. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Hearing Changes How We Perceive Gender
Think about the confused feelings that occur when you meet someone whose tone of voice doesn't seem to quite fit with his or her gender. Neuroscientists focus on the brain's processing of such sensory information in a new study that concludes that hearing fundamentally changes visual experience. The researchers weigh in with findings that contribute to provocative evidence about multisensory processing of our world that has been emerging in recent years. Expandable Electrodes Safe And Effective For Radiofrequency Ablation O
The use of expandable electrodes with multiple tips in the treatment of liver tumors by radiofrequency ablation (RFA) is safe and effective, making it a useful alternative to surgery in selected patients, say researchers from the University of Brescia in Italy. Novel Protein Complex Enables Survival In Hostile Environment
Biswarup Mukhopadhyay and Eric Johnson from the Virginia Bioinformatics Institute at Virginia Tech have discovered a novel enzyme that represents an ancient detoxification system and provides a clue to the development of early metabolism on earth. Early Behavior Problems Appear To Lead To Peer Rejection And Friendles
Rejection and lack of friends in elementary school has been linked to behavior problems in the early grades. Rejection and lack of friends did not put children at risk for delinquency, but early disruptiveness did. Researchers used reports of children's level of anxiety and disruptiveness at ages 6 and 7, combined with measures of peer relationship several years later. These measures were then compared against depression, loneliness, and delinquency at ages 12 and 13. Hurricane Katrina: Information on Charitable Giving, Tax Relief Issues

Patients With Diabetes Need Better Advice About Home Glucose Monitorin
A new study calls for better advice about home blood glucose monitoring for patients with non-insulin dependent (type 2) diabetes. Some experts believe that daily self monitoring helps to control blood glucose levels and it is often recommended. But others believe that self monitoring is complex and inconvenient and can lead to feelings of frustration and guilt. As such, there is still no firm agreement about the role and value of self monitoring for patients with type 2 diabetes. How to act on high readings was a consistent problem.
