Athens, Ga. – Even when at rest, the human body is a flurry of activity. Like a microscopic metropolis locked in a state of perpetual rush hour traffic, the trillions of cells that make us who we are work feverishly policing the streets, making repairs, building new structures and delivering important cargo throughout the bustling organic society.

We would all like to believe that there is a kind of karma in life that guarantees those who cheat eventually pay for their bad behavior, if not immediately, then somewhere down the line. But a study of a new gene in the amoeba Dictyostelium discoideum suggests that, at least for amoebae, it is possible to cheat and get away with it.

Misguided killer T cells may be the missing link in sustained tissue damage in the brains and spines of people with multiple sclerosis, findings from the University of Washington reveal. Cytoxic T cells, also known as CD8+ T cells, are white blood cells that normally are in the body's arsenal to fight disease.

Multiple sclerosis is characterized by inflamed lesions that damage the insulation surrounding nerve fibers and destroy the axons, electrical impulse conductors that look like long, branching projections. Affected nerves fail to transmit signals effectively.

ORLANDO, Fla., January 11, 2013 – Men tend to store fat in the abdominal area, but don't usually have much in the way of hips or thighs. Women, on the other hand, are more often pear-shaped—storing more fat on their hips and thighs than in the belly. Why are women and men shaped differently? The answer still isn't clear, but it's an issue worth investigating, says Steven R. Smith, M.D., director of the Florida Hospital – Sanford-Burnham Translational Research Institute for Metabolism and Diabetes. That's because belly fat is associated with higher risks of heart disease and diabetes.

Washington, DC (January 8, 2013) – The CDC reports that 77% of males wash their hands when leaving the restroom. Recent research, published in the journal Human Communication Research, found that this figure increased to 86% among men who were primed with messages in bathrooms.

Scientists have identified the chemical 'fingerprints' given off by specific bacteria when present in the lungs, potentially allowing for a quick and simple breath test to diagnose infections such as tuberculosis.

Publishing their study today, 11 January, in IOP Publishing's Journal of Breath Research, the researchers have successfully distinguished between different types of bacteria, as well as different strains of the same bacteria, in the lungs of mice by analysing the volatile organic compounds (VOCs) present in exhaled breath.

Women with pre-eclampsia are at a higher risk of complications following delivery and should continue to be monitored for up to 72 hours, suggests a new review published today (11/01/13) in The Obstetrician and Gynaecologist (TOG).

The review analyses the health risks associated with postnatal hypertension, elevated blood pressure that occurs after childbirth, and looks at the women at risk of this condition and treatments available.

Women should wait at least 12 months before trying for a baby following weight loss surgery and need further advice and information on reproductive issues, suggests a new evidence-based literature review published today (11/01/13) in The Obstetrician & Gynaecologist (TOG).

The review looks at the safety, advantages and limitations of bariatric surgery and multidisciplinary management of patients before, during and after pregnancy.

Herbal and complementary medicines could be recommended as an alternative to hormone replacement therapy (HRT) for treating postmenopausal symptoms says a new review published today in The Obstetrician and Gynaecologist (TOG).

The review outlines the advantages and limitations of both pharmacological and herbal and complementary treatments for women with postmenopausal symptoms.

RAPID deterioration in mangrove health is occurring in the Sundarbans, resulting in as much as 200m of coast disappearing in a single year.

A report published today (11th Jan) in Remote Sensing by scientists from the Zoological Society of London (ZSL) states that as human development thrives, and global temperature continues to rise, natural protection from tidal waves and cyclones is being degraded at alarming rates. This will inevitably lead to species loss in this richly biodiverse part of the world, if nothing is done to stop it.

Thousands of individuals have had kidneys removed unnecessarily because doctors misdiagnosed their disease.

A new, international study published in The Lancet indicates that approximately one of every five individuals with kidney tumors common in patients with tuberous sclerosis complex (TSC), a genetic disorder, has had a kidney removed. Moreover, 40 percent had some kind of surgical procedure performed.

Think of the epigenome like a giant musical mixing board, turning up or down the expression of various genes. A University of Colorado Cancer Center study published today in the journal PLOS Genetics shows that in cancer, not only can genes themselves go bad, but abnormal changes in the epigenetic mixing board can unfortunately change the expression of these genes. Researchers hope to play the role of sound engineers, controlling these harmful epigenomic changes to turn down cancer itself or perhaps sensitize cancers to existing drugs.

Boston, MA – Current standards for classifying foods as "whole grain" are inconsistent and, in some cases, misleading, according to a new study by Harvard School of Public Health (HSPH) researchers. One of the most widely used industry standards, the Whole Grain Stamp, actually identified grain products that were higher in both sugars and calories than products without the Stamp. The researchers urge adoption of a consistent, evidence-based standard for labeling whole grain foods to help consumers and organizations make healthy choices.

Availability of CT colonography (CTC), commonly known as virtual colonoscopy, is increasing colorectal cancer (CRC) screening rates across military medical facilities. Inclusion of CTC as a Healthcare Effectiveness Data and Information Set® (HEDIS®)-compliant colorectal cancer (CRC) screening test can potentially raise overall screening rates, according to a study in the January issue of the Journal of the American College of Radiology.
