Daily exercise staves off negative effects of over-eating during Christmas holidays

Even if you consume significantly more calories than you burn off this Christmas, a short, daily bout of exercise will stave off most of the negative effects of over-eating and inactivity, according to scientists at the University of Bath.

Potential pathway for drug development using photoreactions

For chemists, natural substances are compounds formed by organisms to fulfill the myriad biological functions. This biological activity makes them very interesting for industrial applications, for example as active agents in medication or as plant protection agents.

Brain's primary cortex generates efficiently compressed sensory information

Ten million bits - that's the information volume transmitted every second with every quick eye movement from the eye to the cerebrum. Researchers from the Ruhr-Universit-t Bochum (RUB) and the University of Osnabr-ck describe the way those data are processed by the primary visual cortex, the entry point for the visual information into the brain, in the journal "Cerebral Cortex".

E. coli evolution studies may lead to better treatments

Going back in time to compare evolutionary changes in several thousand generations of E. coli, a University of Houston biologist hopes to one day be able to isolate a bacterial pathogen and predict the likelihood it will become resistant to a particular antibiotic.

Consumption of marijuana is twice as large as previously estimated in Washington state

Marijuana consumption in Washington state is about twice as large as previously estimated, according to a new RAND Corporation study.

Pelvic radiation therapy to treat uterine cancer may increase risk of developing bladder cancer

Radiation therapy used to treat uterine cancer may increase a patient's risk of developing bladder cancer. That is the conclusion of a recent study published in BJU International.

UCLA researchers find no evidence of association between iron levels and atherosclerosis risk

A UCLA research team has found no evidence of an association between iron levels in the body and the risk of atherosclerosis, the hardening and narrowing of the arteries that leads to cardiovascular disease, the No. 1 killer in the U.S.

Extracts from pecan shells may be effective at protecting meats

The majority of consumers that eat or buy organic products do not want synthetic antimicrobials or antioxidants added to their foods and prefer a "clean label". A study in the Journal of Food Science published by the Institute of Food Technologists (IFT) showed that extracts from pecan shells may be effective at protecting meats, such as chicken from listeria growth.

Researchers discover that adult stem cells suppress cancer during dormant phase

Researchers at UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have discovered a mechanism in adult stem cells by which the cells suppress their ability to initiate cancer during their dormant phase, an understanding that could be exploited for better cancer prevention strategies.

DCC gene involved in adolescent brain development may play a role in mental health vulnerability

As many parents of mentally ill adults will confirm anecdotally, the first symptoms of "something not quite right" with their children begin to appear during the teen years. It is known that during this teenaged phase of brain development, adolescents are particularly vulnerable to psychiatric disorders, including schizophrenia, depression and drug addiction.

Researchers discover molecular "switch" in receptor that controls cell behavior

If scientists can control cellular functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body.

Measuring changes in certain proteins may better predict the progression of ALS

Measuring changes in certain proteins -- called biomarkers -- in people with amyotrophic lateral sclerosis may better predict the progression of the disease, according to scientists at Penn State College of Medicine.

Researchers hope for a pharmacological solution to treat cocaine addiction

Imagine kicking a cocaine addiction by simply popping a pill that alters the way your brain processes chemical addiction. New research from the University of Pittsburgh suggests that a method of biologically manipulating certain neurocircuits could lead to a pharmacological approach that would weaken post-withdrawal cocaine cravings. The findings have been published in Nature Neuroscience.

New gene mutation helps doctors give more accurate diagnosis of mitochondrial myopathy

A new gene mutation which will help doctors give a more accurate diagnosis of a particular type of brain and muscle disease in children has been discovered for the first time by University of Leeds experts.

Study provides important new perspective on how we look at bladder cancer biology

Bladder cancer will kill upward of 170,000 people worldwide this year, but bladder cancer isn't fatal in the bladder. Instead, in order to be fatal the disease must metastasize to faraway sites. The question has been this: does localized, non-muscle invasive bladder cancer eventually become the more dangerous, muscle-invasive form of the disease, or are NMI and MI bladder cancers genetically distinct from the start?

Genetically targeted drugs used for lung cancer may also have applications in colorectal cancer patients

A University of Colorado Cancer Center study published online ahead of print in the journal Molecular Cancer Research shows that ALK and ROS1 gene rearrangements known to drive subsets of lung cancer are also present in some colorectal cancers. These results imply that drugs used to target ALK and ROS1 in lung cancer may also have applications in this subset of colorectal cancer patients.

Research: Smoking alters several genes

The fact that smoking means a considerable health risk is nowadays commonly accepted. New research findings from Uppsala University and Uppsala Clinical Research Center show that smoking alters several genes that can be associated with health problems for smokers, such as increased risk for cancer and diabetes

Moderate drinking may bolster our immune system and help fight off infection: Study

Medical science has known for years that people who drink moderate amounts of alcohol actually have a reduced risk of death. In general, they are healthier and have better cardiovascular function that those who don't drink alcohol at all.

Exposure to dust from homes with dogs may alter immune response to allergens

A new study suggests that exposure to dust from homes with dogs may alter the immune response to allergens and other asthma triggers by affecting the composition of the gut microbiome-the community of microbes that naturally colonize the digestive tract.

Scientists reveal how MRSA strain rapidly rises to prominence

Scientists believe they have an explanation for how the most common strain of methicillin-resistant Staphylococcus aureus rapidly rose to prominence. Research published in mBio-, the online open-access journal of the American Society for Microbiology, suggests that the strain recently acquired a number of genes from common skin bacteria that allow it to grow and thrive on the skin where other strains of MRSA cannot.
