Sexual satisfaction: Treating a woman with oxytocin also benefits her male partner

Thu, 18/05/2017 - 12:51pm
A new study showed that the sexual response of men, whose female partners had been treated with the "bonding hormone" oxytocin or a placebo, was enhanced – even to the extent of improving their erectile function. This effect was not a function of the substance administered, so that the result is attributable to the improvement in communications within the long-term relationship.

Mechanisms behind sensory deficits in Parkinson's disease

Thu, 18/05/2017 - 12:51pm
Although Parkinson’s disease is often associated with motor symptoms such as stiffness, poor balance and trembling, the first symptoms are often sensory and include a reduced sense of touch and smell. In a study on mice, researchers have now been able to identify neural circuits and mechanisms behind this loss of sensory perception. The study may open avenues to methods of earlier diagnosis.

More cancers diagnosed at early stage following increase in health insurance coverage

Thu, 18/05/2017 - 12:51pm
Cancer is most curable when it’s detected at its earliest stages. An analysis of nearly 273,000 patients showed that between 2013 and 2014 there was a 1% increase in the percentage of breast, lung, and colorectal cancers diagnosed at the earliest, most treatable stage. Following full implementation of the Affordable Care Act (ACA), this study is the first to explore changes in the proportion of cancers – those that can be detected through screening – diagnosed at stage I.

HPV vaccination may reduce oral HPV infections, but still under-utilized

Thu, 18/05/2017 - 12:51pm
In one of the first large studies to explore the possible impact of HPV vaccination on oral HPV infections, researchers found it may confer a high degree of protection. The study of young adults in the United States showed that the prevalence of high-risk HPV infection was 88% lower among those who reported getting at least one vaccine dose than among those who were not vaccinated.

The Charlie Sheen effect on HIV testing

Thu, 18/05/2017 - 12:30pm
On Nov. 17, 2015, actor Charlie Sheen publicly disclosed he was HIV-positive on NBC's Today Show. In previous research, scientists found that Sheen's disclosure corresponded with millions of online search queries for HIV prevention and testing. A follow-up study finds it also led to more sales of in-home HIV testing kits.

Temperatures in the Arctic are

Thu, 18/05/2017 - 12:30pm
Temperatures in the Arctic are increasing twice as fast as in the rest of the globe, while the Antarctic is warming at a much slower rate. A new study shows that land height could be a 'game changer' when it comes to explaining why temperatures are rising at such different rates in the two regions.

Using graphene to create quantum bits

Thu, 18/05/2017 - 12:30pm
In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

Engineering heart valves for the many

Thu, 18/05/2017 - 12:30pm
Medical researchers announced today a cross-institutional team effort to generate a functional heart valve replacement with the capacity for repair, regeneration, and growth. The team is also working towards a GMP-grade version of their customizable, scalable, and cost-effective manufacturing process that would enable deployment to a large patient population. In addition, the new heart valve would be compatible with minimally invasive procedures to serve both pediatric and adult patients.
