Researchers discover that learning suffers if brain transcript isn't transported far out to end of neurons

Neuroscientists at Georgetown University Medical Center have solved a mystery that lies at the heart of human learning, and they say the solution may help explain some forms of mental retardation as well as provide clues to overall brain functioning.

Common mechanisms may underlie autism's diverse mutations

Many of the seemingly disparate mutations recently discovered in autism may share common underlying mechanisms, say researchers supported in part by the National Institute of Mental Health (NIMH), a part of the National Institutes of Health (NIH). The mutations may disrupt specific genes that are vital to the developing brain, and which are turned on and off by experience-triggered neuronal activity.

An automated wearable artificial kidney

Two researchers from UCLA and the Veterans Affairs Greater Los Angeles Healthcare System have developed a design for an automated, wearable artificial kidney, or AWAK, that avoids the complications patients often suffer with traditional dialysis.

Potential new way to prevent graft-versus-host disease

A new University of Michigan study in mice suggests that a drug recently approved to fight cancer tumors is also able to reduce the effects of graft-versus-host disease, a common and sometimes fatal complication for people who have had bone marrow transplants.

How alcohol impacts heart and stroke risk may differ for men and women

The volume of alcohol consumption may have a significantly different effect on heart and stroke risk in men and women, according to a study of Japanese people published in Stroke: Journal of the American Heart Association.

Researchers identify brain cells related to fear - paves way for more effective PTSD treatments

The National Institute of Mental Health estimates that in any given year, about 40 million adults (18 or older) will suffer from some form of anxiety disorder, including debilitating conditions such as phobias, panic disorders and post-traumatic stress disorder (PTSD). It is estimated that nearly 15 percent of U.S. soldiers returning from Iraq and Afghanistan develop PTSD, underscoring the urgency to develop better treatment strategies for anxiety disorders.

Scientists view tiny fibers of working muscles in live humans with microendoscopy technique

Using an unusual microscope with a tip the size of a needle, Stanford researchers are now able to look at tiny fibers of working muscles in live humans, with minimum discomfort to the patient-a development patients are sure to welcome.

Scientists identify 22 genes that control embryonic stem cell fate

Scientists have identified about two dozen genes that control embryonic stem cell fate. The genes may either prod or restrain stem cells from drifting into a kind of limbo, they suspect. The limbo lies between the embryonic stage and fully differentiated, or specialized, cells, such as bone, muscle or fat.

Australian naturopaths in favour of regulation

Naturopaths are strongly in favour of regulation of their industry, a University of Queensland researcher has found.

Advances in RNA research

RNA, the transporter of genetic information within the cell, has emerged from the shadow of DNA to become one of the hottest research areas of molecular biology, with implications for many diseases as well as understanding of evolution. But the field is complex, requiring access to the latest equipment and techniques of imaging, gene expression analysis and bioinformatics, as well as cross-pollination between multiple scientific disciplines.

Researchers measure movements smaller than one-billionth of a meter in ion channels

Each thought or action sends a million electrical signals pulsing through your body. At the heart of the process of generating these electrical impulses is the ion channel.

UGA discovery could lead to new ways to attack cancers by blocking their ability to grow

Human cancer cells divide and conquer. Unless physicians can control that division with surgery, chemotherapy or radiation, the wildly dividing cells will eventually destroy a person's life.

Novel approach shows potential to become an emergency treatment for heart attack patients

Researchers at The Children's Hospital of Philadelphia have manipulated cell activity that occurs during the interruption of blood flow to strongly protect heart tissue in animal studies. The finding has the potential to become an emergency treatment for heart attack patients, particularly since already existing drugs might be pressed into service to produce the protective effects.

Lipid Association responds to new cholesterol guidelines for kids

When the American Academy of Pediatrics (AAP) issued its recommendation on July 7 regarding the treatment of children with high cholesterol, it generated a strong response from the community of medical professionals and patients. The National Lipid Association (NLA), a group of healthcare professionals who specialize in cholesterol and heart disease issues, believes that the AAP has acted in the interests of patient care by raising the issue of lipid abnormalities in children.

46 percent of Americans show biologic exposure to the deadly toxins found in cigarettes

A new report issued today by the Centers for Disease Control (CDC) exemplifies the need for nonsmoking Americans to be better protected against exposure to secondhand smoke. The report finds that 46 percent of Americans show biologic exposure to the deadly toxins found in cigarettes. Even more startling are the millions of children this statistic includes.

More research needed into effects of flavonoids and flavonoid-rich food sources on heart disease

More research is needed into food compounds which could reduce the risk of heart disease, according to a systematic review of trials carried out so far.

Heat waves when in hospital

Deaths due to high temperatures occur so quickly that patients do not have time to be admitted to hospital. This is why prevention campaigns are necessary to try and reduce the negative effects of the heat on health. This is pointed out in new research undertaken at the Hospital Universitario Gregorio Maranon, Madrid.

A micro-sized sewing machine for DNA

Japanese scientists have made a micro-sized sewing machine to sew long threads of DNA into shape. The work published in the Royal Society of Chemistry journal Lab on a Chip demonstrates a unique way to manipulate delicate DNA chains without breaking them.

Researchers crack final part of the immune system code

A group of researchers at the Technical University of Denmark and the University of Copenhagen have developed models of neural networks that make it possible to simulate how the body protects itself from disease and predict the immune system's access codes.

Scientists predict new uses for existing drugs from their side effects

Researchers from the European Molecular Biology Laboratory (EMBL) discovered a new way to make use of drugs' unwanted side effects. They developed a computational method that compares how similar the side effects of different drugs are and predicts how likely the drugs act on the same target molecule. The study, published in Science this week, hints at new uses of marketed drugs.
