A Californian population based study has found that if everyone in the US reduced their daily salt intake by 3 grams – half a teaspoon – the annual number of deaths could be slashed by up to 92,000. In addition, the number of new people who get cardiovascular disease each year could drop by [...]... Read more »

After searching for websites about depression (‘‘depression,’’ ‘‘depression treatment,’’ and ‘‘depression help’’) with a popular search engine: Google, the authors of this work carefully examined the websites. The websites were evaluated on accountability, interactivity, esthetics, readability and content quality. They also used the brief DISCERN as a content quality indicator for general consumers. They found [...]

At today's panel, Putting the Social Back in CSR (CSR = corporate social responsibility) at the Paley Center for Media, Jamie Daves, executive director of Think Social, began the discussion by reminding the audience (and panelists) of social media's potential. Characterizing it as both dangerous and powerful, he drew upon examples where revolutions in communication methods had profound impact on

As I'm sure most of you are aware, the human species isn't really in immediate danger from dying out due to lack of mating partners (other reasons, I leave up to you). And after all, if all else fails, a trip to a sperm bank can often be arranged. But what about those rare animals growing steadily rarer from the encroachment of humans on their habitat? Well this is when you need to lend a hand. It's time to preserve some...eland semen.

A 23 year-old male is brought to your ED by a friend. He appears anxious, distressed and confused. His friend volunteers that the patient had seen a GP in the past few weeks as he was feeling depressed. The friend also admitted that the patient occasionally used recreational drugs such as marijuana and ecstasy. Further of examination of the patient was notable for the presence of shaking eye movements, brisk deep tendon reflexes and stiffness of the lower limbs...

Studies of adult neurogenesis often begin with the following sentence: “Adult neurogenesis occurs in all mammals examined, including humans.” More detail-oriented papers might say, “Adult neurogenesis occurs in all mammals examined, including humans…but not bats.” Here, the similarities between bats and humans become more evident than one might expect: it could be an equally long [...]...

IF a rapid series of taps are applied first to your wrist and then to your elbow, you will experience a perceptual illusion, in which phantom sensations are felt along the skin connecting the two points that were actually touched. This feels as if a tiny rabbit is hopping along your skin from the wrist to the elbow, and is therefore referred to as the "cutaneous rabbit". The illusion indicates that our perceptions of sensory inputs do not enter conscious awareness until after the integration of ........ Read more »
Accurate variant detection in massively parallel sequencing data is a significant bioinformatics challenge. Not only do new sequencers offer unprecedented breadth (whole genome) and depth (30x or more), but they suffer coverage biases and error rates that make variant calling difficult. Last year, we published VarScan, our in-house algorithm for SNP and indel detection on [...]... Read more »

The sensory abilities of vertebrates and invertebrates are generally more similar than they are different: both groups can detect light, sound, pressure, and so on. One of the few cases of a sensory ability that seemed to be the domain of vertebrates alone was the ability to detect electrical signals: electroreception. Several fish have it, and use electrical signals to communicate. Platypus have it. Electroreception in fish is one of the best examples of

Long term readers of my blog may know that generally I'm leery of childhood obesity treatment programs.My issues with them are pretty straightforward. I worry about what it will do to the self-esteem and body image of a child to be put through an inter-disciplinary weight management program (kid, you're so fat you need a team of doctors and dietitians to help you); I worry that kids are not emotionally or cognitively mature enough to have insight into treatment (especially younger kids........
