Exercise :: New study weighs benefits of exercise, diets
While exercise and weight loss are equally effective ways to lose weight, exercising helps to maintain muscles, new research finds.

Immunity :: Research suggests beta agonists may alter the immune system
New research at Wake Forest University School of Medicine suggests that certain inhaled asthma medications — as well as similar chemicals our bodies produce during times of high stress — may worsen diseases such as asthma, heart failure and lupus that involve inflammation.
Money :: Two sides of the same coin – Money spurs changes for better and worse
Money changes everything, and that includes changing people’s motivations for the better and their behavior toward others for the worse, according to a new study published in the international journal Science.
Chemistry :: JHU-led team discovers exotic relatives of protons and neutrons
A team of scientists, including four at The Johns Hopkins University, has discovered two new subatomic particles, rare but important relatives of the familiar, commonplace proton and neutron.
E Coli :: Edible food wrap kills deadly E. coli bacteria
Researchers have improved upon an edible coating for fresh fruits and vegetables by enabling it to kill deadly E. coli bacteria while also providing a flavor-boost to food. Composed of apple puree and oregano oil, which is a natural antibacterial agent, the coating shows promise in laboratory studies of becoming long-lasting alternative to conventional produce washes, according to a team of scientists from the US Department of Agriculture (USDA) and the University of Lleida in Spain.
Oral Cancer :: Tooth whiteners do not cause cancer
Common tooth whitening products, which have been used by millions of people, are found to be safe and do not increase the risk of oral cancer when used as directed. This exhaustive review of the literature, including numerous unpublished clinical studies involving over 4,000 human subjects, appeared in an article by Dr. Ian Monroe entitled, “Use of Hydrogen Peroxide-Based Tooth Whitening Products and its Relationship to Oral Cancer,” published in Journal of Esthetic and Restorative Dentistry.
Leukemia :: ‘Tribbles’ protein implicated in common and aggressive form of leukemia
Researchers at the University of Pennsylvania School of Medicine have identified a new protein associated with acute myelogenous leukemia (AML). Several lines of evidence point to a protein called Tribbles, named after the furry creatures that took over the starship Enterprise in the original Star Trek series. Tribbles was first described in fruit flies.
Neanderthal genome sequencing yields surprising results and opens a new door to future studies
The veil of mystery surrounding our extinct hominid cousins, the Neanderthals, has been at least partially lifted to reveal surprising results. Scientists with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Joint Genome Institute (JGI) have sequenced genomic DNA from fossilized Neanderthal bones.
Health Protection Agency Launches New Radiation Dosimetry Service
The Health Protection Agency has today launched an updated service supplying ‘radiation badges’ to people who work with radiation. This new personal dosimetry service uses thermoluminesence dosemeters (TLDs), often known as ‘radiation badges’. These are worn on clothing or laboratory coats and provide a reliable measurement of radiation dose to people in the workplace.
Newly identified strains of Chlamydia trachomatis could produce new diseases
A new study led by a scientist at Children’s Hospital Oakland Research Institute (CHORI) is the first to conclude that Chlamydia trachomatis is evolving at a rate faster than scientists first thought or imagined. Chlamydia trachomatis is a bacterium that is the leading cause of sexually transmitted diseases and the second leading cause of blindness worldwide.
