Cell phone radiation exposure may lead to increased rates of rare cancers

According to new report from Microwave News, the U.S. National Toxicology Program has found increased rates of rare cancers of the heart and brain in animals exposed to cell phone radiation in a long-awaited multi-million dollar two-year study.

Salk scientists discover REV-ERBα protein that controls strength of circadian rhythm

At noon every day, levels of genes and proteins throughout your body are drastically different than they are at midnight. Disruptions to this 24-hour cycle of physiological activity are why jet lag or a bad night's sleep can alter your appetite and sleep patterns for days--and even contribute to conditions like heart disease, sleep disorders and cancers.

Study finds positive link between perceptual difficulty and insular cortex activity

As the difficulty of making a decision based on sensory evidence increases, activity in the brain's insular cortex also increases, according to researchers at Georgia State University.

Research sheds light on how subtle genetic differences in DMD patients produce variation in symptoms

Johns Hopkins researchers report they have inadvertently found a way to make human muscle cells bearing genetic mutations from people with Duchenne muscular dystrophy (DMD).

Meta-genomics analysis tool Taxonomer can rapidly and accurately detect pathogens

Scientists at the University of Utah, ARUP Laboratories, and IDbyDNA, Inc., have developed ultra-fast, meta-genomics analysis software called Taxonomer that dramatically improves the accuracy and speed of pathogen detection.

Novel way of directly activating Bak protein can trigger cell death

Melbourne researchers have discovered a new way of triggering cell death, in a finding that could lead to drugs to treat cancer and autoimmune disease.

Scientists debate role of AAV in causing hepatocellular carcinoma

Liver cancer can be triggered by mutations in cancer driver genes resulting from the insertion of adeno-associated virus (AAV) vectors used to deliver therapeutic genes, although this tumor-inducing role of AAV remains highly controversial.

Metabolic characteristics of CRPC may open new avenues for treatment

Advanced prostate cancer is usually treated by removing androgen, the male hormone that helps it grow. Although initially effective, this treatment often leads to the tumor becoming castration resistant- a lethal condition.

Gene expression patterns of normal tissue may predict survival rates of estrogen receptor-positive breast cancer patients

Breast tissue surrounding tumors could be used to gauge future survival outcomes for women with estrogen receptor-positive breast cancer, a study led by University of North Carolina Lineberger Comprehensive Cancer Center researchers has found.

Smell or taste of food can shorten lifespan by affecting sensory neurons

Animals can perceive changes in many environmental factors such as temperature and the taste or smell of foods. This is achieved by specialized nerve cells called sensory neurons. Interestingly, sensory neurons have been known to control the rate of aging in various animals, including the tiny free living roundworm C. elegans.

Rockefeller scientists develop new technique that captures detailed snapshot of brain activity

When it comes to measuring brain activity, scientists have tools that can take a precise look at a small slice of the brain (less than one cubic millimeter), or a blurred look at a larger area.

Novel method for designing geometric structures created from DNA

Among the valuable holdings in London's Wellcome Library is a rough pencil sketch made in 1953 by Francis Crick. The drawing is one of the first to show the double-helix structure of DNA--Nature's blueprint for the design of sea snails, human beings, and every other living form on earth.

TSRI study shows how specific gene mutation promotes growth of aggressive tumors

Scientists at The Scripps Research Institute have caught a cancer-causing mutation in the act. A new study shows how a gene mutation found in several human cancers, including leukemia, gliomas and melanoma, promotes the growth of aggressive tumors.

External stimulation guides brain circuit’s early development

A healthy brain has just the right ratio of cells that enhance signals (excitatory neurons) and cells that tone down signals (inhibitory neurons). These two sets of neurons start out looking exactly the same, so what determines their roles?

Small drug-like molecule that alters perception of food may hold key to extending human healthspan

Researchers at the Buck Institute have shown a new effect on aging via a small drug-like molecule that alters the perception of food in the nematode C. elegans. Publishing in Aging Cell, researchers "tricked" the worm's metabolism into a state of caloric restriction, extending the animal's lifespan by 50 percent.

Researcher explores whether DBS can help improve life of bipolar disorder patients

Jennifer Sweet, MD, a neurosurgeon at University Hospitals Case Medical Center, recently opened a clinical research study to learn if there is a structural target in the brain for patients suffering from bipolar disorder and whether deep brain stimulation (DBS) can bring them relief.

Spexin harmone may play role in weight gain among teenagers

A Mayo Clinic-led study found that obese teenagers have lower levels of a hormone potentially tied to weight management than teens of normal weights. The study is published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

Study reveals brain mechanism involved in switching between habitual behavior and decision-making

Not all habits are bad. Some are even necessary. It's a good thing, for example, that we can find our way home on "autopilot" or wash our hands without having to ponder every step. But inability to switch from acting habitually to acting in a deliberate way can underlie addiction and obsessive compulsive disorders.

Early-life stress may lead to functional dyspepsia in adulthood

Traumatic events early in life can increase levels of norepinephrine—the primary hormone responsible for preparing the body to react to stressful situations—in the gut, increasing the risk of developing chronic indigestion and anxiety during adulthood, a new study in American Journal of Physiology—Gastrointestinal and Liver Physiology reports.

UT Southwestern study offers more insight into cholesterol transporter

Using X-ray crystallography, UT Southwestern Medical Center researchers have determined the 3-D atomic structure of a human sterol transporter that helps maintain cholesterol balance.
