It’s a love story as old as time itself: boy Asian corn borer moth (Ostrinia furnacalis) meets girl Asian corn borer moth; girl secretes sex pheromones; boy goes through his courtship ritual, a little song-and-dance routine where he rubs his wings against his thorax to produce a soft, whispering sound. It’s a sweet little love [...]... Read more »

The day after Valentine’s Day. Ah! What better day in the year can we find to discuss gonorrhea? In the US alone 700,000 people are infected each year, and 5 million are infected worldwide. In most infected men gonorrhea causes urethral discharge and pain while urinating. The reason is that Neisseria gonhorrea have little hair-like structures called fimbriae. This makes them very sticky and they stick to the urethra’s walls. Then you get inflammation, urethritis and urinatio........ Read more »

The immune system is designed to protect the body against foreign invaders, neutralizing disease and infection. But organisms are all too happy to invite invasions several times a day through a seemingly innocuous act: eating. When food enters the digestive system, it has to be dealt with by the immune system just like everything else [...]... Read more »

Cocaine produces its powerful high by stimulating “reward” signals in the brain, sending users back again and again for more. Cocaine gains this effect, in part, by stimulating a receptor called the metabotropic glutamate receptor 2 (mGluR2).

A little more than a year ago, paleontologists working in Niger announced the discovery of Spinophorosaurus, a sauropod dinosaur with a wicked tail club. Its bones were not the only traces of dinosaurs to be found in the desert area. About three hundred feet from the exceptionally well preserved sauropod skeleton was a trackway containing [...]...

Check back tomorrow for an interview with this study's lead author, Erica Bree Rosenblum.
If life on Earth started over from scratch, would it eventually re-evolve the world we see today? This is the kind of question that makes for an entertaining argument over beers: "Well, without the Chicxulub impact, the dinosaurs wouldn't have gotten out of the way for mammals." "But dinosaurs were already turning into birds!" You might think that to resolve that argument, we'd need a second Earth and four........ Read more »

As any clinician knows, patterns of fat deposition tend to vary greatly even in people with similar amounts of total body fat.

Globular Clusters (GCs) Globular clusters are groups of roughly spherical, densely packed stars. They are thought to have formed at the same time as most galaxies and the stars which make them up are some of the oldest known–thus GCs are an excellent probe of galaxy formation and evolution. They have a high central stellar [...]... Read more »

Many workplaces recognise that besides more cognitive notions of intelligence – our capability to solve problems, use logic, process and judge factual information – they also need Emotional Intelligence (EI): the capability to recognise, make the most of and manage emotion. Now a new theoretical paper makes the case that we should be expanding this concept of EI to include the ability to influence others through emotional displays.EI currently focuses on spotting, dealing with and making sen........

Last Friday’s Theory Lunch was interesting for a reason the speaker didn’t entirely intend.

Cognition researchers should beware assuming that people's mental faculties have finished maturing when they reach adulthood. So say Laura Germine and colleagues, whose new study shows that face learning ability continues to improve until people reach their early thirties.
