Blood biomarker associated with prevalence, severity of Alzheimer's, but not risk of development (April 9, 2011) -- Higher levels in blood of the protein clusterin, also known as apolipoprotein J, are significantly associated with the prevalence and severity of Alzheimer's disease, but not with the risk of onset of new disease, according to a new study. ... > full story

Guidance molecules: New therapy shows novel therapeutic approach to fighting inflammation (April 9, 2011) -- Researchers in Germany have succeeded in finding a new therapeutic approach to certain inflammatory reactions of the body. The approach focuses on guidance molecules, which reduce the body's own immune system to the required level and prevent excessive and damaging inflammation. Possible applications include therapies for inflammation, such as blood poisoning, but also in chronic inflammation and immunological inflammations such as rheumatoid arthritis and organ rejection. ... > full story

Fighting malaria with African plant extracts (April 9, 2011) -- Plants used in traditional African medicine may have an effect on the malaria parasite as well as the mosquitoes that spread the disease. A Norwegian pilot project is now indexing and testing these plants. ... > full story

Frequent shopping prolongs life, study suggests (April 9, 2011) -- A spot of regular 'retail therapy' really does seem to help people live longer, suggests new research. Frequent shopping among the elderly may not always be about buying things, but about seeking companionship or taking exercise, which is easier to do than more formal exercise that usually requires motivation. ... > full story

New drug shrinks cancer in animals, study shows (April 9, 2011) -- A new study showed in animal studies that new cancer drug compounds they developed shrank tumors, with few side effects. ... > full story

E. coli enzyme must move to function (April 9, 2011) -- Slight oscillations lasting just milliseconds have a huge impact on an enzyme's function, according to a new study. Blocking these movements, without changing the enzyme's overall structure or any of its other properties, renders the enzyme defective in carrying out chemical reactions. ... > full story

New clinical trial approach reduces time and costs of many studies (April 9, 2011) -- Doctors are testing a new kind of clinical trial that's not only less costly but guides doctors to switch to the best treatment even before the trial is completed. The new approach -- called a point-of-care clinical trial -- is an alternative to expensive, lengthy, double-blind, placebo-controlled clinical trials to compare drugs and procedures that are already in regular use. ... > full story

Boy Scouts and Girl Scouts: Cookies or careers? (April 9, 2011) -- New research analyzing boy scout and girl scout manuals finds that -- despite positive aspects -- scouts are being fed stereotypical ideas about femininity and masculinity. ... > full story

Is beauty found in the whites of the eyes? 'Red eyes' associated with the sad and unattractive (April 8, 2011) -- Beauty is said to be in the eye of the beholder, but a new study reveals that the reverse is also true; unattractiveness is in the eye of the beheld. Researchers found that people with bloodshot eyes are considered sadder, unhealthier and less attractive than people whose eye whites are untinted, a cue which is uniquely human. ... > full story

Dopamine controls formation of new brain cells, salamander study shows (April 8, 2011) -- A study of the salamander brain has led researchers to discover a hitherto unknown function of the neurotransmitter dopamine. In a new study, they show how in acting as a kind of switch for stem cells, dopamine controls the formation of new neurons in the adult brain. Their findings may one day contribute to new treatments for neurodegenerative diseases, such as Parkinson's. ... > full story

Pancreatic disease: Cells can consume errant molecules to prevent them from eating up organ (April 8, 2011) -- Timing is everything. That's especially true when it comes to the activation of enzymes created by the pancreas to break down food. When the timing is right, those enzymes are activated only when they reach the gut, where they get to work releasing and distributing nutrients that we need to survive. If the timing is wrong and the enzymes are activated too soon, they break down the pancreas itself, which is painful and sometimes fatal. ... > full story

'Dual switch' regulates fat formation: Discovery points to new obesity and diabetes drugs (April 8, 2011) -- New research has identified a key regulator of fat cell development that may provide a target for obesity and diabetes drugs. ... > full story
