Researchers have discovered that low oxygen conditions can trigger the production of proteins that contribute to the spread of breast cancer cells. This is according to a study published in the Proceedings of the National Academy of Sciences.Biologists from Johns Hopkins University found that low oxygen conditions prompted increased production of proteins called RhoA and ROCK1.
Researchers from the University at Buffalo in New York say two bacteria that cause many common infections in children and the elderly, such as strep throat and ear infections, can live outside the human body for long periods of time on various objects, including books, cribs and toys.
Lovers of literature can rejoice: a new study combines the humanities and neuroscience to take a look at what effects reading a novel can have on the brain. Researchers say exploring a book can not only change your perspective, but also it can change your mind - at least for a few days.
Performance anxiety is better helped by telling yourself to get excited rather than to calm down, says a psychologist publishing the results of experiments looking into fear-inducing prospects, such as public speaking and math tests.Simply saying the phrase, "I am excited" out loud was found to improve performance in the studies by Alison Wood Brooks, PhD, of Harvard Business School.
Many of us will have been intrigued by the sound of beatboxing at some point - a highly skilled vocal percussion in which the performer imitates a drum sound with their voice. You may think that compared with standard singing, beatboxing is harsher on the voice. But new research suggests this is not the case.
A new study suggests having chemotherapy before surgery to remove a tumor may benefit more patients with esophageal cancer than previously thought.Tim Underwood, an esophageal surgeon researcher at the University of Southampton in the UK, and colleagues report their findings in the World Journal of Gastroenterology.
By designing an injectable viral vector that targets blood vessels of tumors, researchers from Washington University School of Medicine in St. Louis, MO, have opened new avenues for gene therapy against cancer and other diseases that have abnormal blood vessels.
Alzheimer's disease has become an increasing burden in older patients, which is why research into its causes is a high priority. Now, a new study links concussion history and Alzheimer's, suggesting loss of consciousness could be associated with the build-up of plaques in the brain.
Maximilien de Robespierre was one of the most influential and best known figures in the French Revolution. A lawyer and politician who was guillotined in 1794, he might also have been the first described case of the rare immune disorder sarcoidosis.
Rheumatoid arthritis is an inflammatory disease that affects the lining of the joints, but it can also affect other organs. In a recent international collaboration, researchers have discovered 42 new genetic markers associated with the condition, which they say could open doors to new treatments.
Death rates from metastatic prostate cancer have remained "mostly unchanged over the past 25 years," a study of 19,336 men with an advanced form of the urological disease has found.Publishing their findings online in the journal Cancer, the researchers from the University of California, Sacramento, had been expecting improvements in these mortality rates.
A chemical naturally occurring in the body, already proven to produce a feeling of being full when administered, has found an effective new route via a spray on the tongue, say health researchers from the University of Florida.
As we grow older, our brains reorganize themselves, pruning and streamlining nerve fiber linkages to reduce overall network connectivity while selectively preserving long-distance connections that are crucial to information integration.
Researchers from the Massachusetts Institute of Technology say they have discovered clues as to why a malaria-related parasite, called toxoplasma gondii, can cause blindness in some people but not in others. This is according to a study published in PLOS Pathogens.Toxoplasma gondii is a single-celled parasite that causes a disease known as toxoplasmosis.
Obesity researchers have found that African-American women need to consume fewer calories or do more activity to achieve the same weight-loss rates as Caucasian women who start at a similar size. They cite a lower metabolic rate to explain the greater difficulty in reducing obesity.
Allergic reactions to peanuts and tree nuts can range from mild to life-threatening. But new research suggests that pregnant women who are not allergic to the nuts/legumes and who eat more of them during pregnancy lower the risk of their child developing an allergy to the food.This is according to a study published in JAMA Pediatrics.
