Eye contact is commonly considered a sign of self-confidence and a means for emotional connection. In contrast, a person who averts their gaze is often considered shy, fearful, embarrassed or lying. Many a self-help manual has touted the power of eye contact, with direct eye contact suggested to help one quickly gain an individual’s attention, [...]... Read more »

The Broken Windows theory of crime reduction, made famous by Malcolm Gladwell's bestselling book The Tipping Point, has received new robust empirical support from a series of studies by Dutch researchers.According to the theory, more serious crimes can be averted by reducing low level crime such as littering and graffiti. Gladwell attributed the dramatic fall in crime in New York in the 90s to the zero tolerance approach of the police at that time, which effectively put into practice the advice ........ Read more »

One of the coolest adaptions insects use to survive is when they try to look like something else in order to fool predators into not eating them. Normally, they look like something which tastes bad or a group of harmful species mimic each other to spread that blanket of protection. Occasionally, though, some take a [...]... Read more »

Are you from Birmingham? Or, more importantly, have you got a Brummie accent? If so, research suggests that you should stay quiet, as the accent is perceived as not intelligent. A recent study by Smith & Workman (2008), which was presented in this year's Annual Conference of the British Psychological Society (BPS) confirmed this finding. Participants looked at different photos of women whilst listening to female voices speaking in different accents. They were then asked to rate each photo in........ Read more »

We are in the midst of massive upheaval in the world’s ecosystems, driven by species invasions and the sixth mass extinction in Earth’s history. How will these changes in biodiversity affect the functions of ecological communities? Will the functions of ecological systems that humans rely on for survival, such as production of oxygen, be impacted by all this upheaval?Answering these questions requires that biologists have a good metric for biodiversity.

Brain activity changes when people undergo spiritual or religious experiences. This isn't surprising, of course, since it's the brain that generates these mental states. Studying just how brain activity changes as people think religious thoughts or experience spiritual or transcendental experiences gives a window into how they are generated in the brain and how they link to other kinds of experiences.The religious tend to take a dualist approach to these kinds of results, arguing that these chan........

Ah, the humble proton. Simple, stable, and able to drastically affect the chemistry of other molecules — and nowhere more so than in the Interstellar Medium (ISM). H2 molecules, for instance are readily protonated in dense interstellar clouds, forming H3 , and playing a key role in the formation of hydrides like ammonia and methane. CO forms HCO , N2 forms HN2 and so on. So what about those polycyclic aromatic hydrocarbon (PAH) molecules I keep talking about…?... Read more »

A recent study by Bryson et al. has found that moderate to severe alcohol misuse increases the likelihood that patients won’t take their medication properly.

Spatial navigation is the process on which we rely to orient ourselves within the environment and to negotiate our way through it. Our ability to do so depends upon cognitive maps, mental representations of the surrounding spaces, which are constructed by the brain and are used by it to calculate one's present location, based on landmarks in the environment and on our movements within it, and to plan future movements.
The term "cognitive map" was first used in a landmark 1948 paper, in wh........ Read more »

Rebekah Wukits discusses recent findings about ratite evolution for Bio 135.Ratite evolution has been debated for centuries. Some of the earliest evolutionary biologists questioned whether or not ratites had a linear evolution or if the major groups had had independent origins. Richard Owen proposed that living ratites had much more in common with other flight capable groups while being united by the “arrested development of wings unfitting them for flight”. In 1951, two ornithologists, Mayr........ Read more »

One of the key questions about galaxies concerns the process in which they form. Galaxies are made up of stars, but in general stars do not form in isolation – except for the very first stars in the universe, which we discussed here.More normally, stars form simultaneously in close proximity to each other as part of the larger process of galaxy formation. But galaxy formation can happen in one of at least two different ways. In the first case, the baryonic matter that will eventually form ........ Read more »

Serendipitous timing has allowed researchers in Canada to capture the brain activity of a woman experiencing a spontaneous sense of someone else being in the room with her, when really she was alone.This feeling of sensed presence is rather common. For example, more than half of patients who suffer a head injury without loss of consciousness go on to experience a sensed presence during the subsequent year. It's also common among people with temporal lobe epilepsy. Curiously, the presence is per........ Read more »

Fibre optic sensors really do shine. No, I don't just mean when you pass light down one end and see it come out of the other, I mean they can be made to perform some pretty clever tasks, often triumphing over their electronic rivals. A fibre sensor fabricated by splicing together three different types of optical fibre and capable of measuring temperatures up to 1000°C, has recently been demonstrated by scientists in South Korea†.

One of the major cognitive factors in prolonging depression is ruminative (or “analytical”) self focus. It’s a trap that’s difficult to avoid - most people who recognize that they suffer from depression will start asking themselves questions like “Why can’t I just snap out of it?”, “Why do I feel this way?”, or, “What’s wrong [...]...

Over evolutionary time, the easiest way to deal with a competitor is to do something different - if your competitor eats big seeds, say, it may be easier to start eating small seeds than to fight for the big ones. This idea goes all back to the Origin, wherein Darwin proposed that competition drives evolutionary diversification, with living things dividing up available resources into ever-finer... Read more »

A well-known recording company recently released a new recording of Glenn Gould performing the Goldberg Variations. The recording date was summer 2006. Curious, not? Another pianist with the same name as the legendary Canadian musician?Actually, the recording was made using measurements of the original, old recordings that were used to remake the performance on a computer-controlled grand piano, a modern pianola. In the recording studio a grand piano was moving its keys without someone behind th........ Read more »
