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.

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.

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.

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.

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.

Scientists generate the most precise map of genetic recombination ever

Genetic recombination, the process by which sexually reproducing organisms shuffle their genetic material when producing germ cells, leads to offspring with a new genetic make-up and influences the course of evolution.

Neuron to publish Prana's PBT2 preclinical research on Alzheimer's disease

Prana Biotechnology Ltd. has announced the publication of key research findings with its lead Alzheimer's Disease drug, PBT2.

Combining medical knowledge to save lives

Cardiovascular disease (CVD) is the biggest killer among chronic diseases, claiming 17 million lives globally every year. Yet doctors can only attribute 50% of cardiovascular diseases to known risk factors.

Gene silencer and quantum dots reduce protein production to a whisper

More than 15 years ago, scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.

Young women's breast cancers more aggressive and less responsive to treatment

Young women's breast cancers tend to be more aggressive and less responsive to treatment than the cancers that arise in older women, and researchers at the Duke Comprehensive Cancer Center and the Duke Institute for Genome Sciences and Policy may have discovered part of the reason why: young women's breast cancers share unique genomic traits that the cancers in older women do not exhibit.

Genetic change in dopamine transporter supports a role for dopamine signaling in ADHD

A genetic change in the dopamine transporter - one of the brain's dopamine-handling proteins - makes it behave as if amphetamine is present and "run backward," Vanderbilt University Medical Center investigators report this week in The Journal of Neuroscience.

Diabetes effects sperm quality

Diabetes in men has a direct effect on fertility, a scientist told the 24th annual conference of the European Society of Human Reproduction and Embryology today (Wednesday 9 July).

New understanding of how malaria parasite survives in and totally changes red blood cells

A new study-done on a scale an order of magnitude greater than anything previously attempted in the field of malaria-has uncovered an arsenal of proteins produced by the malaria parasite that allows it to hijack and remodel human red blood cells, leaving the oxygen-carrying cells stiff and sticky.

Specific gene may make women more susceptible to alcoholism

A particular gene variant might make women more susceptible to alcoholism. At least, a study carried out by the Universities of Bonn and Sweden's Karolinska Institute makes this a plausible conclusion.

Transgenic tomatoes as edible vaccine carriers for Alzheimer's disease

The humble tomato could be a suitable carrier for an oral vaccine against Alzheimer's disease, according to HyunSoon Kim from the Korea Research Institute of Bioscience and Biotechnology (KRIBB) in Korea and colleagues from Digital Biotech Inc. and the Department of Biological Science at Wonkwang University.

FDA approves novel genetic test for patients with breast cancer

The U.S. Food and Drug Administration has approved a novel genetic test for determining whether patients with breast cancer are good candidates for treatment with the drug Herceptin (trastuzumab).

Farm-raised tilapia fish contains potentially dangerous fatty acid combination

"Farm-raised tilapia, one of the most highly consumed fish in America, has very low levels of beneficial omega-3 fatty acids and, perhaps worse, very high levels of omega-6 fatty acids, according to new research from Wake Forest University School of Medicine.

Researchers detail types of genes necessary for brain

Researchers from Harvard Medical School and Brandeis University have successfully completed a full-genome RNAi screen in neurons, showing what types of genes are necessary for brain development. Details of the screen and its novel methodology are published July 4th in the open-access journal PLoS Genetics.
