Potential drug for treatement of Alzheimer's disease investigated Posted: 31 Aug 2012 09:37 AM PDT A compound developed to treat neuropathic pain has shown potential as an innovative treatment for Alzheimer's disease, according to a new study.

Customer service is an emotional experience Posted: 31 Aug 2012 09:36 AM PDT You can probably recall a customer service experience that left you feeling good. A recent study has shown not only that positive emotion from sales staff is contagious to a customer, but that a satisfied customer also improves the salesperson's mood.

Intervention helps children with sickle cell disease complete MRI tests without sedation Posted: 31 Aug 2012 09:36 AM PDT Researchers report success using a targeted educational approach to teach young sickle cell disease patients to remain motionless during MRI scans, making the process safer.

Fear and driving opportunity motivated changes in driving behavior after 9/11 Posted: 31 Aug 2012 08:21 AM PDT A catastrophic event -- such as a terrorist attack or a natural disaster -- often strikes twice. There is the damage caused by the event itself, as lives are lost or left in ruin. But there is also the second act, catalyzed by our response to the catastrophic event, which can cause as much damage as the first. New research examines the impact that fear and driving opportunity had on driving behavior following the 9/11 terrorist attacks.

Affluent people less likely to reach out to others in times of trouble? Posted: 31 Aug 2012 07:42 AM PDT Crises are said to bring people closer together. But a new study suggests that while the have-nots reach out to one another in times of trouble, the wealthy are more apt to find comfort in material possessions.

New, less expensive nanolithography technique developed Posted: 31 Aug 2012 07:41 AM PDT Researchers have developed a new nanolithography technique that is less expensive than other approaches and can be used to create technologies with biomedical applications.

Glass shape influences how quickly we drink alcohol Posted: 31 Aug 2012 07:41 AM PDT The speed at which we drink alcohol may be influenced by the shape of the glass we drink from, according to new research. This could be a target to help control the problematic levels of drunkenness that are becoming increasingly common in our society.

Danish scientists solve old blood mystery: New intriguing knowledge on blood hemoglobin Posted: 31 Aug 2012 07:41 AM PDT Scientists in Denmark have solved an old puzzle, which since the 1960s from many sides has been regarded as impossible to complete. The challenge was to solve the structure of the protecting protein complex that forms when hemoglobin is released from red cells and becomes toxic. This toxic release of hemoglobin occurs in many diseases affecting red cell stability, e.g. malaria.

Breathable treatment to help prevent asthma attacks Posted: 31 Aug 2012 07:41 AM PDT Researchers in the UK are presenting details of a treatment that could help asthmatics fight infections that trigger 80 percent of asthma attacks.

First simultaneous robotic kidney transplant, sleeve gastrectomy performed Posted: 31 Aug 2012 07:38 AM PDT A 35-year-old Chicago woman is the first patient in the world to have a combined procedure that offers new hope for obese kidney patients.

The beat goes on: Research yields two 'firsts' regarding protein crucial to human cardiac function Posted: 31 Aug 2012 07:38 AM PDT Researchers have achieved significant benchmarks in a study of the human cardiac protein alpha-tropomyosin, which is an essential, molecular-level component that controls the heart's contraction on every beat. Using an imaging method called atomic force microscopy, scientists have achieved two 'firsts': the first direct imaging of individual alpha-tropomyosin molecules and the first demonstrated examples of a measure of the human cardiac protein's flexibility.
