Researchers uncover vital clues of how the brain erases long term memories

Vital clues about how the brain erases long term memories have been uncovered by researchers. The study in rats reveals how forgetting can be the result of an active deletion process rather than a failure to remember.

Altered metabolism of two essential amino acids helps drive development of glioblastoma

The altered metabolism of two essential amino acids helps drive the development of the most common and lethal form of brain cancer, according to a new study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Excess activation of LOX may play causative role in progression of cardiac failure

Heart failure is a progressive condition, where structural and functional alterations of the ventricle limit the ability of the heart to either fill or eject blood. There are approximately 550,000 new cases of heart failure each year with a prevalence of nearly 5 million; most patients die within five years of diagnosis.

New study raises possibility of therapeutic intervention for brain blood vessel disease

Cerebral cavernous malformations (CCM) are the most common cause of stroke in young people. These malformations also known as Cavernomas are present in 0.1-0.5% of the population, with about 60% causing symptoms. Currently there is no drug treatment available for CCM.

German scientists use DNA molecules to make nanoscale component

In order for a machine to perform work, it needs parts that move relative to each other. This also holds true for nanoscale machines. German scientists have now used DNA molecules to make a nanoscale component that makes it possible for two individual parts to move relative to each other. As reported in the journal Angewandte Chemie, this component could be used as a molecular guide bearing and may form the basis for more complex systems.

Study may help identify unborn children at higher risk for birth defects

Researchers at the University of Toronto have discovered a novel function performed by the breast cancer 1 protein (BRCA1), which regulates DNA repair. Well known for the role it plays in breast and ovarian cancer, this study revealed that the BRCA1 protein actually plays a much broader biological role, particularly in protecting the developing embryo from the damaging effects of reactive oxygen species (ROS).

Purdue University-led researchers determine structure of Zika virus

A team led by Purdue University researchers is the first to determine the structure of the Zika virus, which reveals insights critical to the development of effective antiviral treatments and vaccines.

New UCLA study reveals how the brain combines sound and vision

A new UCLA psychology study provides insights into how the brain combines sound and vision. The research suggests that there is not one sole mechanism in the brain that governs how much our senses work together to process information.

Study links voluntary exercise during pregnancy to more physically active children

Baylor College of Medicine researchers have discovered that female mice that voluntarily exercise during pregnancy have offspring that are more physically active as adults. The research appears in The FASEB Journal.

Aging reduces axonal regeneration after spinal cord injury

Older Americans are increasingly active, and this lifestyle shift has contributed to the rise in average age of a person experiencing a spinal cord injury. The changing demographic calls for a better understanding of how aging impacts recovery and repair after a spinal cord injury.

Tumor suppressor p53 gene twice as likely to be defective in autistic children

A large study by researchers with the UC Davis MIND Institute has found that a gene whose role is to suppress cellular damage from environmental stressors is nearly twice as likely to be defective in children with autism spectrum disorder (ASD), and that the deficit is also present in their fathers.

Experimental urine test identifies 92% of men with elevated PSA levels

An experimental urine test that detects genetic changes associated with prostate cancer identified 92 percent of men with elevated PSA (prostate-specific antigen) levels who had high-grade cancers, according to a study published today in JAMA Oncology online.

Study points to possible new genetic risk factor for celiac disease

Researchers have identified a common variant in a non-coding RNA that may contribute to the intestinal inflammation that occurs in people with celiac disease. The findings point to a possible new risk factor for developing celiac disease in people with celiac disease risk genes.

Commonly used fungicides could cause gene expression changes in brain cells

Scientists at the UNC School of Medicine have found a class of commonly used fungicides that produce gene expression changes similar to those in people with autism and neurodegenerative conditions, including Alzheimer's disease and Huntington's disease.

DNA changes may affect a person's lifespan

Scientists have identified DNA changes that can cut a person's lifespan by up to three years.

Right side of the brain reorganizes itself after stroke to help recover speech-motor functions

New research suggests that looking at structures in the right side of the brain may help predict who will better recover from language problems after a stroke, according to a study published in Neurology, a medical journal of the American Academy of Neurology.

Penn researchers discover molecular mechanism that underlies common cerebrovascular disease

Cerebral cavernous malformations (CCMs) are clusters of dilated, thin-walled blood vessels in the brain that can cause stroke and seizures, yet exactly how they form is somewhat of a mystery. Now, a team from the Perelman School of Medicine at the University of Pennsylvania has discovered the molecular mechanism that underlies this common cerebrovascular disease. They published their results this week online ahead of print in Nature.

Scientists develop mouse model to gain new insights into genetic mechanisms underlying AML

A novel mouse model of a highly lethal form of acute myeloid leukemia (AML) offers a new tool for scientists working to better understand this disease and research new therapeutic targets.

Understanding neuronal feedback could provide new insight into visual perception

Ever see something that isn't really there? Could your mind be playing tricks on you? The "tricks" might be your brain reacting to feedback between neurons in different parts of the visual system, according to a study published in the Journal of Neuroscience by Carnegie Mellon University Assistant Professor of Biological Sciences Sandra J. Kuhlman and colleagues.

Study finds correlation between male sex hormones and oral health

More than 20 species of macaques, the most widely distributed nonhuman primates in the world, socialize in lively troops and make frequent appearances on National Geographic documentaries. But, what can we learn from one of our closest primate relatives about our own oral health?
