The investigational cancer vaccine tecemotide, when administered with the chemotherapeutic cisplatin, boosted immune response and reduced the number of tumors in mice with lung cancer, a study has shown. "There aren't an...

Physical activity and diet have positive impact on health, regardless of fat levels, a new study has indicated. "Since most children with obesity find it challenging to lose and maintain weight loss over time, improving ...

The implementation of health care reform in Massachusetts -- principally the expansion of health insurance coverage to nearly everyone in the state - was associated with a small but consistent increase in emergency depar...

About six percent of colorectal cancers are diagnosed within three to five years after the patient receives a clean colonoscopy report, according to a population-based study. These cancers may have been overlooked at the...

Throughout a cell's life, corrective mechanisms act to repair DNA strand breaks. The exception is during the critical moment of cell division, when chromosomes are most vulnerable. Researchers found out why DNA repair sh...

Researchers examined how muscle physiology effects leanness. They found that while rats with 'lean genes' burned a similar amount of calories at rest as those with 'obese genes,' the muscles of lean rats burned much more...

Children in military families who relocate have an increased odds of suffering mental health problems, finds a large new study. Mental health issues in kids who moved included attention deficit and conduct disorders and ...

Is irritable bowel syndrome (IBS) caused by genetics, diet, past trauma, anxiety? All are thought to play a role, but now, for the first time, researchers have reported a defined genetic defect that causes a subset of IB...

Two proteins that control how cells metabolize glucose play a key role in the formation of human stem cells. Studies suggest these proteins which also play a role in the process that transforms normal cells into cancer s...

The surface of immune system cells is home to a number of receptors which are able to detect pathogens. As soon as these receptors are activated, inflammation occurs and the body's defense mechanisms kick in. A receptor ...

From smart phones to smart cars, both public and private entities must consider the needs of older adults in order to help them optimize the use of new technologies, according to experts.

One of the mysteries of modern genetics has been solved: how acquired traits can be passed between generations in a process called epigenetic inheritance. The new work finds that cells don't know to silence some genes ba...

Anticancer agents that inhibit tumor growth by targeting a cell-cycle regulatory protein called CDK4 might actually promote the development and progression of certain B-cell lymphomas. The research suggests that CDK4 inh...

Breastfeeding until at least nine months of age increases prevalence in the gastrointestinal tract of Lactobacilli and Bifidobacteria, species which are known to contribute to development of a healthy immune system, acco...

Putting a drone in a ball could add an antigravity component to typical ball games, much like the winged snitch in the Harry Potter books     

(Phys.org) --University of Oregon physicists using a supercomputer and mathematically rich formulas have captured fundamental insights about what happens when objects moving freely jam to a standstill.

(Phys.org) --Physicists are one step closer to developing the world's first room-temperature superconductor thanks to a new theory from the University of Waterloo, Harvard and Perimeter Institute.

The best model yet of how genes affect face shape will one day give police DNA photofits of suspects - and allow us to gaze into extinct humans' faces     

The U.S. military is investing in manned and unmanned aircraft that can take off, hover and land vertically. These so-called vertical takeoff and landing (VTOL) vehicles could one day transport troops, weapons or cargo t...

Never understood the International Date Line? This informative animation shows how the IDL works.

Oil from the Exxon Valdez spill lingers, as do disputes about its current impact on wildlife. John Wiens asks what a quarter century of research can tell us     

The White House launched a new effort Wednesday to make climate data more accessible to the public.
