When it comes to condom use among heterosexual couples, there's evidence that women are often expected to be the sensible ones, in terms of raising and enforcing the issue. A new study published in the Archives of Sexual Behaviour suggests this isn't just unfair, it's unwise too – both men and women show a similarly increased inclination for risk-taking when they are sexually aroused.The Canadian research team, led by Shayna Skakoon-Sparling, recruited 144 heterosexual undergrads to take part ........

mTOR is dysregulated in a range of tumour types and can be targeted with mTOR inhibitor treatments such as everolimus and sirolimus. Tuberous sclerosis complex (TSC) and sporadic lymphangioleiomyamatosis (LAM) result from mutations in TSC1 or TSC2 that disrupt mTOR signalling (Carsillo et al., 2000, Glasgow et al., 2010). The associated aberrant cell growth, survival and movement results in the formation of slow growing tumours in various tissues and pulmonary cyst formation with loss of pulmona........ Read more »

A recent paper in Science reports the results of a large-scale effort to test reproducibility in psychological science. The results have caused much discussion (as well they should) in both general public and science forums. I thought I would offer my perspective as the lead author of one of the studies that was included in the reproducibility analysis. I had heard about the project even before being contacted to participate and one of the things that appealed to me about it was that they were t........ Read more »

Fuels and fungi have a long-standing and intricate relationship. Before we get into the juicy details, let's examine the players.Traditionally speaking, a fuel is any organic substance (e.g. wood, coal, and oil) containing lots of stored chemical energy within the bonds holding its atoms together. This energy can be released via combustion, which we harness to move cars forward and generate electricity.Fungi are a huge group of organisms largely describable in terms of what they lack: locomotion........

The scope and mechanism of significant brain injury in football and other sports is unclear.One research challenge is the identification of early signals indicated risk for remote cognitive decline and dementia.For example, repeated concussions at age 20 with brain injury may not produce clinical cognitive deficits for 20 or 30 years. Early identification of risk and counseling of individuals may reduce trauma exposure and cognitive decline.There are no valid tests of brain imaging in high-risk ........ Read more »

It's 50 years since the American neurologist Norman Geschwind published his hugely influential Disconnexion Syndromes in Animals and Man, in which he argued that many brain disorders and injuries could best be understood in terms of the damage incurred to the white-matter pathways connecting different areas of the brain.To mark this anniversary, an international team of researchers has used modern brain imaging techniques to reveal, in an open-access article for Cerebral Cortex, the likely damag........

It's easy to understand why so many people have been tempted by the futuristic-looking foc.us brain stimulation headset. The manufacturers promise their product will increase brain speed and plasticity and improve mental abilities such as working memory. What's more, the device uses a technology that's usually described as "non-invasive" – transcranial direct current stimulation, or tDCS for short – to send currents apparently safely into your prefrontal cortex.There is ample lab r........
