Yes, you secretly like giving your money to the government. University of Oregon scientists have found that doing things like donating money to charity or even paying your taxes can give you the same sort of satisfaction you derive from feeding your own hunger pangs.

Subjecting mice to repeated emotional stress, the kind we experience in everyday life, may contribute to the accumulation of neurofibrillary tangles, one of the hallmarks of Alzheimer’s disease, report researchers at the Salk Institute for Biological Studies. While aging is still the greatest risk factor for Alzheimer’s disease, a number of studies have pointed to stress as a contributing factor.Top left: In unstressed animals the hippocampus, which is involved in the formation of memories and learning, is free of phosphorylated tau.

The consumption of sweetened soft drinks by children has more than doubled between 1965 and 1996 but few studies have been able to investigate the link between diet and the body’s energy balance control systems in early life. Now scientists at Aberdeen’s Rowett Research Institute have been able to model how the young body responds to overeating.

The long supposed connection between mind and music has been further demonstrated by an international collaboration of physicists led by Simone Bianco and Paolo Grigolini at the Center for Nonlinear Science at the University of North Texas. A statistical analysis reveals a remarkable similarity between the distributions produced by music compositions and brain activity.

A newly discovered transmembrane protein called "Wurst" (sausage) appears to play a decisive role in breathing – possibly in all animals, from flies to human beings. This insight is reported by scientists from the University of Bonn and the Göttingen-based Max Planck Institute for Biophysical Chemistry.

A protein found primarily in the lens of the eye could be the critical "tipping point" in the spiral of inflammation and damage that occurs in multiple sclerosis, researchers at the Stanford University School of Medicine report.

This protein - alphaB-crystallin - is not normally found in the brain, but develops in response to the injuries inflicted on nerve cells by multiple sclerosis. The nerve-cell injuries can cause people to suffer loss of motor control and even paralysis.

A new therapy to re-activate silenced genes in patients who suffer from neurodegenerative diseases or stroke is being developed by researchers at the University of Illinois at Chicago and Cornell University.

During and after a stroke, certain cellular events take place that lead to the death of brain cells. Compounds that inhibit a group of enzymes called histone deacetylases can modulate gene expression, and in some cases produce cellular proteins that are actually neuroprotective -- they are able to block cell death.

As a result of mapping the structure of the protein complex implicated in autism spectrum disorders, a research team led by scientists at University of California, San Diego have discovered how particular genetic mutations affect this complex and contribute to the developmental abnormalities found in children with autism. Their work should help scientists pinpoint the consequences of other genetic abnormalities associated with the disorder.Neuroligin/neurexin complex in the synapse

Although most Americans believe they know what brought down the World Trade Center twin towers on Sept. 11, 2001, civil engineers are still seeking answers to questions that could save lives in the future.

Structural engineers need to know from a scientific perspective what happened to the buildings during the terrorist attacks in order to prevent future failures. The search for answers continues with the help of a state-of-the-art animated visualization created by researchers at Purdue University.Source: Purdue University

A decade or so ago, a spate of high profile legal cases arose in which people were accused, and often convicted, on the basis of “recovered memories.” These memories, usually recollections of childhood abuse, arose years after the incident occurred and often during intensive psychotherapy.

So how accurate are recovered memories? The answer is not so clear. In fact, this question has lead to one of the most contentious issues in the fields of psychology and psychiatry.
