	Study reveals mechanism behind most common form of inherited Alzheimer's disease A study from researchers at Massachusetts General Hospital (MGH) and Brigham and Women's Hospital (BWH) reveals for the first time exactly how mutations associated with the most common form of inherited Alzheimer's disease produce the disorder's devastating effects. Appearing in the March 4 issue of Neuron, the paper upends conventional thinking about the effects of Alzheimer's-associated mutations in the presenilin genes and provides an explanation for the failure of drugs designed to block presenilin activity.
	Common antidepressant may hold the key to heart failure reversal A team led by researchers at Temple University School of Medicine (TUSM) found that a commonly prescribed antidepressant restored heart function in mice with heart failure, a finding that could lead to clinical trials for a disease long considered irreversible.

	Using fruit flies to understand how we sense hot and cold Innately, we pull our hand away when we touch a hot pan on the stove, but little is known about how our brain processes temperature information. Northwestern University scientists now have discovered how a fruit fly's brain represents temperature, mapping it neuron by neuron, which has implications for understanding the much more complex human brain and how it responds to sensory stimuli.

	Study shows who benefits most from statins New research suggests that widely used statin therapy provides the most benefit to patients with the highest genetic risk of heart attack. Using a relatively straightforward genetic analysis, the researchers assessed heart attack risk independently of traditional risk factors such as age, sex, so-called good and bad cholesterol levels, smoking history, family history and whether the patient has diabetes.

The study was lead by Jacqueline Halladay, MD, associate professor, Department of Family Medicine.
	There's no evidence human pheromones exist – no matter what you find for sale online The idea of human pheromones is intuitively appealing, conjuring up the idea of secret signals that make us irresistible to potential partners. But this connection of pheromones with sex may be the wrong way to look at the issue – because despite 45 years of study and various claims over the years there's still not a lot of evidence that human pheromones exist at all.

Using CBT in this way could potentially help to prevent mental illnesses occurring in at-risk people.
GDNF not needed by the midbrain dopamine system A key factor in the motor symptoms associated with Parkinson's disease is the gradual destruction of dopamine neurons. The glial cell-derived neurotrophic factor, or GDNF, has been proven to protect dopamine neurons in test tube conditions and in test animal models for Parkinson's disease. GDNF and its close relative, neurturin, have also been used in experimental treatments of patients with severe Parkinson's disease. The results have been promising, but vary widely in terms of efficacy. At the moment, two companies are conducting tests to determine the clinical effects of GDNF on Parkinson's sufferers.
