Smokers looking to quit could be helped by a cigarette-crushing video game, according to a study published in the journal CyberPsychology & Behavior. A group of Canadian researchers discovered that smokers placed in a virtual reality environment full of cigarettes to be destroyed showed a significant reduction in nicotine cravings.
The study took 91 regular smokers [...]... Read more »

One of those scientific papers that seems to have been written with the blogosphere in mind: biologists have just published records of fellatio by the fruit bat Cynopterus sphinx. Apparently C. sphinx females are pretty flexible -- they lick their mate's penis during copulation, which evidently induces him to stay in longer (see the graph below, with drawing). The authors offer a handful of non-mutually-exclusive hypotheses for the adaptive benefit of the behavior, ranging from lubrication to in........ Read more »

As strange as it might seem, the living African and Asian elephants are only the remnants of what was once a very diverse array of proboscideans. In the not-too-distant past elephants and their closest relatives occupied Africa, Europe, Asia, North America, Central America, and South America, but almost all of them had perished by about 10,000 years ago.* Of these recently-extinct forms the most iconic was the woolly mammoth, Mammuthus primigenius, which was covered in long coats of shaggy hai........

If you don't know someone's age, over time they may let out clues that tell you when they were born based on what they remember, or things they claim to have done. This can be very inaccurate. My wife said something the other day that would cause anyone to infer that she was at least ten years older than she is, but it turns out the TV show she was referring to came to her home as syndicated re-runs. (My own personal memory of the recently deceased Soupy Sales is a similar example.)

The Society for Neuroscience(SfN) was formed 40 years ago and to commemorate the occasion, the journal of Neuroscience has made some review articles open-access. They are written by leading luminaries in their filed and are somewhat scholarly- though I found some of them pretty accessible too.

Product placements in movies and TV shows are becoming so commonplace that my kids now cynically take note of them whenever they appear. It wasn't always that way. In 1982 when I first saw E.T. I had no idea that Elliott's use of Reeses' Pieces to lure E.T. into his home was part of a clever marketing ploy that had been pre-arranged with the multinational conglomerate selling the candy. Now that nearly every household has a DVR allowing viewers to fast-forward through commercials, advertisers ar........ Read more »

An earlier post looked at the connection in the USA between religion and a high teen pregnancy rate. High fertility and religion often goes together, and whenever this topic comes up the immediate question is: will the religious inexorably 'out-breed' the nonreligious?The answer to that rather depends on how religion (or lack of it) is transmitted through the generations.

As a species we are consumed by love. Ask yourself, how many cultural productions (films, stories, songs, dances, arts) do not have love, the loss of love or the absence of love as their central theme? Would you be satisfied with what was left over? That fact that love has so much power over us is just one reason why evolutionary research is so fascinating.

FOLLOWING the surgical removal of a body part, amputees often report sensations which seem to originate from the missing limb. This is thought to occur because the brain's model of the body (referred to as the body image) still contains a representation of the limb, and this leads to the experience that their missing limb is still attached to their body. Occasionally, amputees say that they cannot move their phantom limbs. They are perceived to be frozen in space, apparently because they cannot ........ Read more »

You can read my previous posts on this drug here (1, 2).The Research: Part 2The second study published on the efficacy of agomelatine was by Kennedy and Emsley (2006, 3).This was a 6-week, double-blind, randomized, placebo-controlled study involving 212 patients. Dosage ranged from 25-50mg/day (dose adjustment at week 2 for poor responders). No other active comparator (e.g., paroxetine) was used in this study.

Of special interest are the always popular "motif recognition domain"-"short flexible peptide" interactions. However, post translational modifications and regulation by disorder are also discussed.

A new Nature letter has the potential to abnormally extend (until extinction) the whole spectrum of reporter genes. So far, "reporters" were those genes coding for an easily detectable product (i.e., those coding for fluorescent or luminescent proteins). Wei Min and other Harvard's colleagues introduced a new technique, namely stimulated emission microscopy, that seems able to turn into mini-lasers any non-fluorescent light-absorbing molecule. It means that several chromophores, such as haemog........ Read more »
