Resolving debate about how tumors spread 2013-01-08

By University of California, San Diego Health Sciences

Scientists have shown for the first time how cancer cells control the ON/OFF switch of a program used by developing embryos to effectively metastasize in vivo, breaking free and spreading to other parts of the body, where they can proliferate and grow int

Precisely engineering 3-D brain tissues 2013-01-08

By Massachusetts Institute of Technology

Borrowing from microfabrication techniques used in the semiconductor industry, engineers have developed a simple and inexpensive way to create three-dimensional brain tissues in a lab dish.

Study sheds light on how pancreatic cancer begins 2013-01-08

By University of California, San Diego Health Sciences

Scientists examined the tumor-initiating events leading to pancreatic cancer (also called pancreatic ductal adenocarcinoma or PDA) in mice. Their work may help in the search for earlier detection methods and treatments.

Running too far, too fast, and too long speeds progress 'to finish line of life' 2013-01-08

By BMJ-British Medical Journal

Vigorous exercise is good for health, but only if it's limited to a maximum daily dose of between 30 and 50 minutes, say researchers.

Adapting fish defenses to block human infections: Antimicrobial peptide of fish gills inspire clean surfaces 2013-01-08

By Worcester Polytechnic Institute

Living in an environment teaming with bacteria and fungi, fish have evolved powerful defenses, including antimicrobial peptides located in their gills. Undergraduate researchers are studying the biology and mechanics of one of those peptides with the aim

Sleep duration affects hunger differently in men and women 2013-01-08

By American Academy of Sleep Medicine (AASM)

By Ohio State University Medical Center

Results from a recent study show women who wait more than 60 days to begin treatment for advanced breast cancer face significantly higher risks of dying than women who start therapy shortly after diagnosis.

Making music together connects brains 2013-01-08

By Max-Planck-Gesellschaft

Anyone who has ever played in an orchestra will be familiar with the phenomenon: the impulse for one’s own actions does not seem to come from one’s own mind alone, but rather seems to be controlled by the coordinated activity of the gr

Scientists describe the genetic signature of a vital set of neurons 2013-01-08

By NYU Langone Medical Center

Scientists have identified two genes involved in establishing the neuronal circuits required for breathing, findings which could advance treatments for spinal cord injuries, ALS.

Biology behind brain development disorder: Mutations in the gene, UBE3B, cause a rare genetic disorder in children 2013-01-08

By Wellcome Trust Sanger Institute

A combination of sequencing and mouse models were used to identify the gene responsible for a brain developmental disorder seen in four patients. The study also shows that the biology uncovered in the mouse model helps to understand the symptoms in patien

Autism severity may stem from fear 2013-01-08

By Brigham Young University

New research on autism shows that children with the diagnosis struggle to let go of old, outdated fears. Even more significantly, the study found that this rigid fearfulness is linked to the severity of classic symptoms of autism, such as repeated movemen

By European Society of Cardiology (ESC)

The scents which permeate our health spas from aromatic essential oils may provide more benefits than just a sense of rest and well-being.

Which Group of Asian-American Children Is at Highest Risk for Obesity? 2013-01-08

By Mary Ann Liebert, Inc., Publishers

Asian-American children have been at low risk for being overweight or obese compared to other racial and ethnic groups in the U.S., but that may be changing. Yet as rates of overweight and obesity rise, the risk appears to vary depending on the Asian coun

Specific protein essential for healthy eyes described 2013-01-08

By Hebrew University of Jerusalem

Researchers have just found that a specific protein is essential not only for maintaining a healthy retina in the eye, but also may have implications for understanding and possibly treating other conditions in the immune, reproductive, vascular a

Alcoholic fly larvae need fix for learning 2013-01-08

By Cell Press

Fly larvae fed on alcohol-spiked food for a period of days grow dependent on those spirits for learning. The findings show how overuse of alcohol can produce lasting changes in the brain, even after alcohol abuse stops.

Important factor in fat storage and energy metabolism 2013-01-08

By Joslin Diabetes Center

Scientists have identified a cell cycle transcriptional co-regulator – TRIP-Br2 – that plays a major role in energy metabolism and fat storage. This finding has the potential to lead to new treatments for obesity.

Diabetics with cancer dangerously ignore blood sugar 2013-01-08

By Northwestern University

When people with Type 2 diabetes are diagnosed with cancer -- for which they are at higher risk -- they ignore their diabetes to focus on cancer. But high blood sugar is more likely to kill them. When they received diabetes education after a cancer diagno

Relative length of adults' fingers indicator of verbal aggression: Prenatal exposure to testosterone linked 2013-01-08

By International Communication Association

A new study links verbal aggression to prenatal testosterone exposure. Scientists used the 2D:4D measure to predict verbal aggression. This study is the first to use this method to examine prenatal testosterone exposure as a determinant of a communication

Findings support safety of whooping cough vaccine for older adults 2013-01-08

By Infectious Diseases Society of America

A new study of the safety of the tetanus-diphtheria-acellular pertussis vaccine supports the recommendation that those 65 and older get the vaccine to protect themselves and others, particularly young babies, from pertussis. The findings come as reported
