Humans with a high motor excitability have a better working memory than humans with a low excitability. This was shown in a study conducted by scientists from the Transfacultary Research Platform at the University of Basel. By measuring the motor excitability, conclusions can be drawn as to the general cortical excitability –...

Visceral leishmaniasis is a serious disease in many countries, causing 20,000 to 40,000 deaths worldwide every year. Most cases in the American continent occur in Brazil where this insidious disease has, in several years, caused more mortality than dengue.

People who prefer to combine quick, intuitive decisions with analysis, make the best decisions in a crisis situation, a new study shows. Many organisations depend every day on the ability of their leaders and staff to make good decisions in crisis situations. This is true for the armed forces,...

La diminuta isla de Nieves, en el norte de las Antillas Menores, es uno de los pocos lugares vírgenes que quedan en el Caribe. Ahora trata de convertirse también en el más verde, al sumarse a la creciente lista de países de la región que apuestan a una energía limpia: la geotérmica. Los...

Mientras esquiva los charcos de agua contaminada con sus zapatos andrajosos, Sabeh, de 14 años, se las arregla para encontrar el camino hasta el mercado del campamento de refugiados de Al Shati, una de las zonas más pobladas y pobres de la ciudad palestina de Gaza. Le pregunta a un hombre que vende...

Meibomian gland dysfunction (MGD) is the leading cause of dry eye disease, which affects tens of millions of Americans. However, there is no FDA-approved treatment for MGD. Researchers from the Schepens Eye Research Institute/Massachusetts Eye and Ear and Harvard Medical School have just identified a potential therapy. Fuente :...

A systematic review of 66 research papers focused on the treatment of skin ulcers suggests that most are so technically flawed that their results are unreliable. And even of those that pass muster, there is only weak evidence that some treatments work better than standard compression therapy or...

An antibody that blocks a component of a key signaling pathway in the respiratory airways could help the immune system rid the body of the influenza virus, a new study suggests. The findings, from a team at The Research Institute at Nationwide Children's Hospital, not only offer a new approach to...

About 3.5 million cases of child abuse are reported in the United States every year. Now a Tel Aviv University study has found that when parents are physically abusive, children tend to accommodate it -- but when the abuse is sexual, they tend to fight or flee it unless it is severe. The findings...

A new study has identified a link between certain genes affected by testosterone and antibody responses to an influenza vaccine. The findings, published in PNAS, suggest that testosterone levels may partially explain why men often have weaker responses to vaccines than women. The study, led by researchers at Stanford...

In the first study of human hunter-gatherer movement patterns, a team led by UA anthropologist David Raichlen has found that the tribe's movements while foraging can be described by a mathematical pattern called a Lévy walk -- a pattern that also is found in the movements of many other animals, from sharks to honey bees.

Computer scientists are constantly searching for ways to squeeze ever more bandwidth from communications networks. Now a new approach to understanding a basic concept in graph theory, known as "vertex connectivity," could ultimately lead to communications protocols -- the rules that govern how digital messages are exchanged --...

A new study finds nearly one in four healthcare workers' hands were contaminated with Clostridium difficile spores after routine care of patients infected with the bacteria. The study was published in the January issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of...

A new study shows that coronary artery calcium (CAC) screening, an assessment tool that is not currently recommended for people considered at low risk, should play a more prominent role in helping determine a person's risk for heart attack and heart disease-related death, as well as the need for angioplasty or bypass surgery....

New research shows mortality rates are two times higher in postmenopausal women with rheumatoid arthritis and anti-cyclic citrullinated peptide antibodies. Findings published in the American College of Rheumatology journal Arthritis & Rheumatism, soon to be called Arthritis & Rheumatology, indicate the higher mortality...

Both real and sham weekly acupuncture treatments eased hot flashes and other side effects of anticancer drug treatment in a small, preliminary study of breast cancer patients, Baltimore researchers have found. Fuente : http://www.eurekalert.org/pub_releases/2013-12/jhm...

Breast cancer patients experience fewer side effects while being treated with a widely used drug called an aromatase inhibitor when they get acupuncture -- either the real treatment or a "sham" procedure, according to a new study led by researchers at the University of Maryland Marlene and Stewart Greenebaum Cancer Center....

A new analysis has found that both real and sham acupuncture treatments may help alleviate side effects of drugs commonly used to treat breast cancer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings may help clinicians improve care for cancer patients. The results also...

Within two years of implementation, Blue Cross Blue Shield of Massachusetts' Alternative Quality Contract -- a contracting model, based on global payment and pay-for-performance -- had a small but significant positive effect on the quality of pediatric care, according to a new study from Boston Children's Hospital.

Researchers have found new clues to how plants evolved to withstand wintry weather. Scientists constructed an evolutionary tree of more than 32,000 species of flowering plants -- the largest time-scaled evolutionary tree to date. By combining their tree with freezing exposure records and leaf and...
