A medication commonly taken for Type II diabetes, which is being found in freshwater systems worldwide, has been shown to cause intersex in fish –or male fish that produce eggs. The study determined exposure to the diabetes medicine metformin causes physical changes in male fish exposed to doses similar to the amount in wastewater effluent.... Read more »

No one expects a human infant to slide into the world with a good grasp of grammar. Marmosets, another kind of chatty primate, are also poor conversationalists when they're young. But their parents seem to teach them how it's done. Young marmosets learn the cardinal rule of having a conversation: don't interrupt. And if they mess up, their parents give them the silent treatment.
Common marmosets (Callithrix jacchus) live in large family groups in the forests of Brazil. "Because marmosets ... Read more »

A funny thing happened on the way to the publisher. In a world first, China has successfully created genetically modified human embryos. It was certainly an amazing piece of science, but the paper was rejected by both Nature and Science. Not because the study was flawed, or because the data was falsified, the paper was rejected for ethical reasons.... Read more »

In 2012 the USA saw the highest number of pertussis (whooping cough) cases since 1955. New research finds that a likely explanation for this rise in disease is a drop in the degree of vaccine protection for each vaccinated individual. The team worked with 60 years of pertussis disease data to determine what best explained the recent increase in the disease.... Read more »

Recently we blogged about an emerging demographic subgroup: the lumbersexual. After reading the flurry of mainstream media articles about this group, here is how we described them: “As far as we can tell, the lumbersexual is an urban male (typically White and heterosexual) who dresses like a lumberjack even though he is far from a […]
Wait! Could that be a lumbersexual in your venire panel?

Acceptance is defined in Acceptance and Commitment Therapy (ACT) as “a willingness to remain in contact with and to actively experience particular private experiences (Hayes, Jacobson, Follette, Dougher, 1994) (eds): Acceptance and Change: Content and Context in Psychotherapy. Reno, Context Press, 1994), and from this Lance McCracken and colleagues developed the Chronic Pain Acceptance Questionnaire. This measure has two dimensions: willingness to experience pain and engaging in values-dir........ Read more »

For decades, frustrated parents and teachers have barked at fidgety children with ADHD to “Sit still and concentrate!” But new research shows that if you want ADHD kids to learn, you have to let them squirm. The foot-tapping, leg-swinging and chair-scooting movements of children with attention-deficit/hyperactivity disorder are actually vital to how they remember information and work out complex cognitive tasks....

Many years of research have shown that for students from lower-income families, standardized test scores and other measures of academic success tend to lag behind those of wealthier students. Well now a new study offers another dimension to this so-called “achievement gap”After imaging the brains of high- and low-income students, they found that the higher-income students had thicker brain cortex in areas associated with visual perception and knowledge accumulation....

According to a large study just published in the Journal of Autism and Developmental Disorders, there's no correlation between brain anatomy and self-reported autistic traits.
Dutch researchers P. Cedric M. P. Koolschijn and colleagues looked at two samples of young Dutch adults: an 'exploration' sample of 204, and a separate 'validation' group of 304 individuals.
Most of the participants did not have autism. The researchers looked for associations between various aspects of brain ... Read more »

If a time machine was available, would it be right to kill Adolf Hitler when he was still a young Austrian artist to prevent World War II and save millions of lives? Should a police officer torture an alleged bomber to find hidden explosives that could kill many people at a local cafe? When faced with such dilemmas, men are typically more willing to accept harmful actions for the sake of the greater good than women. For example, women would be less likely to support the killing of a young Hitler........ Read more »

Ever hear that old saying an apple a day keeps the Doctor away? Well it might have the right idea, just the wrong person.

We know that hormones affect who we are, even when we aren’t aware of it.

About five million people in the US suffer from heart failure, and approximately half of them die within five years of being diagnosed. Only about 2,500 hundred people a year receive a heart transplant – the treatment of last resort. A new heart can be life-saving, but it is also life-changing. Even under the best conditions, the surgery is complex, and recovery carries a heavy physical and emotional burden.
