Researchers identify 1 of the necessary processes in the formation of long-term memory

A new study that was carried out at the University of Haifa has identified another component in the chain of actions that take place in the neurons in the process of forming memories. This discovery joins a line of findings from previous studies that together provide a better understanding of the most complex processes in nature – the process of memory formation and storage in the human brain. The new study has been published in the prestigious Journal of Neuroscience. more  

UM scientists pinpoint critical molecule to celiac disease, possibly other autoimmune disorders

It was nine years ago that University of Maryland School of Medicine researchers discovered that a mysterious human protein called zonulin played a critical role in celiac disease and other autoimmune disorders, such as multiple sclerosis and diabetes. Now, scientists have solved the mystery of zonulin's identity, putting a face to the name, in a sense. Scientists led by Alessio Fasano, M.D., have identified zonulin as a molecule in the human body called haptoglobin 2 precursor. more

Half of the fish consumed globally is now raised on farms, study finds

Aquaculture, once a fledgling industry, now accounts for 50 percent of the fish consumed globally, according to a new report by an international team of researchers. And while the industry is more efficient than ever, it is also putting a significant strain on marine resources by consuming large amounts of feed made from wild fish harvested from the sea, the authors conclude. Their findings are published in the Sept. 7 online edition of the Proceedings of the National Academy of Sciences (PNAS). more  

Infections may lead to faster memory loss in Alzheimer's disease

Getting a cold, stomach bug or other infection may lead to increased memory loss in people with Alzheimer's disease, according to research published in the September 8, 2009, print issue of Neurology®, the medical journal of the American Academy of Neurology. more

Brain defect implicated in early schizophrenia  

In the first functional magnetic resonance imaging (fMRI) study of its kind, neurologists and psychiatrists at Columbia University have identified an area of the brain involved in the earliest stages of schizophrenia and related psychotic disorders. more

Designing probiotics that ambush gut pathogens  

Researchers in Australia are developing diversionary tactics to fool disease-causing bacteria in the gut. Many bacteria, including those responsible for major gut infections, such as cholera, produce toxins that damage human tissues when they bind to complex sugar receptors displayed on the surface of cells in the host's intestine. more

Study of huge numbers of genetic mutations point to oxidative stress as underlying cause

A study that tracked genetic mutations through the human equivalent of about 5,000 years has demonstrated for the first time that oxidative DNA damage is a primary cause of the process of mutation - the fuel for evolution but also a leading cause of aging, cancer and other diseases. more
