University of Exeter scientists have helped develop an early-warning system to predict the risk of dengue fever outbreaks in Brazil during the forthcoming World Cup.
The study, developed by a team of European scientists, estimates the chances of outbreaks of the mosquito-borne infection disease in Brazil’s administrative areas – or microregions – during this summer’s festival of football. (more…)
Watching films with stressful scenes can trigger changes to the heart’s beating pattern, reports a new study published in the journal Circulation, Arrhythmia and Electrophysiology
Although the changes were small, and not likely to be risky for normal healthy individuals, the team from UCL, King’s College London and Guy’s and St. Thomas’ Hospital found that watching an emotionally charged film clip caused a disturbance to the normal heartbeat and a significant increase in blood pressure.

A three-nation clinical trial found that a vaccine can safely help the vast majority of HIV-positive women produce antibodies against the cancer-causing human papillomavirus, even if their immune system is weak and even if they’ve had some prior HPV exposure.
PROVIDENCE, R.I. [Brown University] — HIV-positive women respond well to a vaccine against the human papillomavirus (HPV), even when their immune system is struggling, according to newly published results of an international clinical trial. The study’s findings counter doubts about whether the vaccine would be helpful, said the Brown University medical professor who led the study. Instead, the data support the World Health Organization’s recommendation to vaccinate women with HIV. (more…)
Where and how you live strongly influences both the type and number of microbes you carry on your hands, according to a new international study led by scientists at Yale and Stanford.
The research identified and analyzed bacteria on the hands of women in Tanzania and graduate students in the United States, finding that bacterial populations were more similar among the subjects within a country than between subjects of different countries. (more…)
Trying to be thin is like trying to be tall, say UCLA psychologists
Girls who are told by a parent, sibling, friend, classmate or teacher that they are too fat at age 10 are more likely to be obese at age 19, a new study by UCLA psychologists shows.
The study looked at 1,213 African-American girls and 1,166 white girls living in Northern California, Cincinnati and Washington, D.C., 58 percent of whom had been told they were too fat at age 10. All the girls had their height and weight measured at the beginning of the study and again after nine years. (more…)
Distinguished statistician discusses probability and statistics in health care

Warum gähnen wir? Wir neigen zum Gähnen bevor wir schlafen gehen oder nach dem Aufwachen, wenn wir uns langweilen oder uns die Inspiration fehlt. Wir gähnen in Erwartung wichtiger Ereignisse und unter Stress. Was haben diese Dinge gemeinsam? WissenschafterInnen der Universität Wien und der Nova Southeastern University und des SUNY College in Oneonta, USA, weisen auf die Verbindung zur Thermoregulierung, insbesondere zur Kühlung des Gehirns hin. Die Ergebnisse ihrer Untersuchungen wurden im Fachmagazin “Physiology & Behaviour” publiziert.
Es ist die allgemeine Annahme, dass Gähnen die Sauerstoffzufuhr erhöht. Allerdings konnten frühere Untersuchungen einen Zusammenhang zwischen Gähnen und erhöhtem Sauerstoffgehalt im Blut nicht bestätigen. Neuere Ergebnisse eines ForscherInnenteams rund um den Psychologen Andrew Gallup vom SUNY College in Oneonta, USA, zeigen vielmehr, dass Gähnen das Gehirn kühlt. (more…)
