Archeological research reveals how ancestral humans have adapted to changing environment

During the Stone Age ancestral humans lived with a variety of animal species along what was an area of wetlands in the middle of the Jordanian desert. The site, in the town of Azraq Basin, has been excavated and has revealed an abundance of tools and animal bones from up to 250,000 years ago, leading to better understanding of how ancestral humans have adapted to this changing environment.

Research illuminates abilities of ADAR1 to ‘hyper-mutate’ tumor suppressor RNAs in leukemia

Writing in the January 3 issue of Cancer Cell, researchers at University of California San Diego School of Medicine report that detection of "copy editing" by a stem cell enzyme called ADAR1, which is active in more than 20 tumor types, may provide a kind of molecular radar for early detection of malignancies and represent a new therapeutic target for preventing cancer cell resistance to chemotherapy and radiation.

Commonly prescribed ADHD drug unlikely to increase cardiovascular risks in children

With more than 1.8 million children in the U.S. being treated annually with drugs for attention deficit hyperactivity disorder, the possibility that such drugs could damage their hearts has been a significant cause of concern for parents and physicians alike.

Bulldogs' screw tails linked to rare inherited syndrome in humans

With their small size, stubby faces and wide-set eyes, bulldogs, French bulldogs and Boston terriers are among the most popular of domestic dog breeds. Now researchers at the University of California, Davis, School of Veterinary Medicine have found the genetic basis for these dogs' appearance, and linked it to a rare inherited syndrome in humans.

Egg metabolites in blood linked to reduced risk of type 2 diabetes

Consumption of one egg every day seems to associate with a blood metabolite profile that is related to a lower risk of type 2 diabetes, a new study conducted in the University of Eastern Finland shows.

Study: Mice lacking PARL protein display specific problems in the nervous system reminiscent of Leigh syndrome

Leuven researchers led by professor Bart De Strooper (VIB-KU Leuven) have identified a new role for PARL, a protein that has been linked to Parkinson's disease.

Higher vitamin C intake crucial for metabolic syndrome patients to halt cycle of antioxidant disruption

A higher intake of vitamin C is crucial for metabolic syndrome patients trying to halt a potentially deadly cycle of antioxidant disruption and health-related problems, an Oregon State University researcher says.

Rockefeller scientists uncover genetic mutation responsible for tuberculosis vulnerability

If you live in the United States, you are unlikely to come into contact with the microbe that causes tuberculosis. Your odds of encountering the microbe are so low, in fact, that risk factors for the disease can easily go unnoticed: If you happened to carry a gene that predisposed you to tuberculosis, you likely wouldn't know.

Study identifies possible new strategies to treat silent seizures in children

As early as 3 months of age, infants with a severe form of epilepsy called Dravet syndrome start having convulsive seizures, during which their arms and legs jerk repeatedly. As they become toddlers, another type of seizure begins to appear.

Molecular signatures reveal why women are more likely to die from glioblastoma

Scientists have discovered molecular signatures that reveal why women are more likely to develop and die from the brain cancer, glioblastoma.

Neuroscientists decipher how brain circuits optimize themselves

Human beings, like other animals, possess an enormous learning capacity that allows for the apprehension of new sensory information to master new skills or to adapt to an ever-changing environment.

Novel sensor monitors beating heart cells with minimal disruption

For the first time, engineers have demonstrated an electronic device to closely monitor beating heart cells without affecting their behavior. A collaboration between the University of Tokyo, Tokyo Women's Medical University and RIKEN in Japan produced a functional sample of heart cells with a soft nanomesh sensor in direct contact with the tissue.

Peptide isolated from spirulina extract may counteract arterial hypertension

Spirulina is more and more celebrated as a "superfood" because of its possible beneficial properties, albeit its mechanism of action is still subjected to investigation. With the scientific name of Arthrospira platensis, spirulina is a cyanobacterium, a bacterium capable of photosynthesis. Sometimes classified as a "blue algae", it was supposedly used as a food by the Aztecs.

Genetically diverse mouse models improves usability for precision medicine for Alzheimer's

Incorporating genetic diversity into a mouse model of Alzheimer's disease resulted in greater overlap with the genetic, molecular and clinical features of this pervasive human disease, according to a study funded by the National Institute on Aging, part of the National Institutes of Health.

MUSC researchers link higher levels of AGEs to ER-positive breast cancer risk

Poor diet and lack of exercise are associated with cancer development, but the underlying biology is not well understood. Advanced glycation end products could offer a biological link to help us understand how certain lifestyle behaviors increase cancer risk or lessen the likelihood that an anti-cancer therapy will be effective.
