Loneliness is a complex set of emotions that encompasses feelings of social isolation, unfilled intimate needs, and heightened feelings of vulnerability. Though transient for some people, chronic loneliness can take a physical and psychological toll on individuals, leading to increased morbidity and mortality. Specifically, new research indicates that loneliness raises blood pressure – a silent [...]... Read more »

Cell biologists make amazing discoveries using cells grown flat on culture dishes, yet the cells in an organism grow and function in three dimensions. Some cell biologists use clever tricks to understand how cells function in three dimensions by using cells cultured in gels, and they find out very valuable information. Throughout biology there are many cases of oriented cell division, during which a cell orients the mitotic spindle on a specific axis. These cell divisions can occur throughout........ Read more »

Humans have been aware of optical illusions for a very long time. Indeed, recently, the study of illusions has provided psychology with many, many illusions. Colman (2006) states that broadly speaking, illusions fall into the following categories:Ambiguous figures, associative illusions, illusory contours, impossible figures, movement illusions, perspective illusions, space-time illusions, stereoscopic illusions, and visual aftereffects.Baldwin IllusionMany illusions actually were developed befo........

How far does corporate social responsibility go? While corporate social responsibility looks good on paper, how far are companies willing to not just talk the talk, but also walk the walk? For example, what should a company do if the authorities in a foreign country are clearing away residential areas (and removing residents without any compensation) to make room for industrial development that may allow said company to expand its offshored manufacturing facilities?

Via Twitter, I noticed a study that claimed to show clinical benefits for Homoeopathy - not for the remedy, but for the consultation style. That aroused my interest. During three years of unexplained infertility, I saw quite a few CAM practitioners, a nutritionist, two herbalists (one Chinese, one Western), a Shiatsu therapist, an aromatherapist, a Structural Integration practitioner, and a woman who practiced Reiki.

Who makes new friends on social networks online? If we are going by the "rich get richer" assumption, we would expect to find that people who are already socially active will find even more friends on SNS. On the other hand, it's possible that those who have troubles forming offline relationships will socialize more on the Web (the "social compensation" model). The third possibility is the "seek and ye shall find" model: people who believe it's possible to create online friendships would be mor........ Read more »

Variety IR8 is the original “Miracle rice” of the 1960s. This carefully-crafted variety has a stunted, semi-dwarf phenotype, which increases it’s harvest index (the proportion of grain biomass to total biomass), and allows it to resist lodging (falling over into the mud), even when heavily fertilized. As with wheat, the creation of dwarf varieties of rice played a major role in the enormous yield gains of the Green Revolution. But now it’s in Continue reading...... Read more »

Autism is a genetic disorder. We've known this ever since the 1970s when studies by Susan Folstein and Michael Rutter showed that identical twins (who share the same random mix of genes from their parents) are much more likely to both be autistic than fraternal (non-identical) twins, who each have a different random mix of genes. These findings were incredibly important and fundamentally changed the way people think about autism. But they didn't tell us which genes cause aut........ Read more »

Aaron Kay a psychologist at the University of Waterloo in Ontario, Canada is interested in how people react when you make them feel like they're not in control of the situation they find themselves in.
He's previously shown that, if you disturb people's sense of control, then they tend to compensate by increasing their belief in a controlling god. In a separate study, he also showed that there's a similar relationship with attitudes to government. What seems to be happening is that, when people........ Read more »

Neuroplasticity is in.Books tell us about The Brain That Changes Itself or advise us on how to Train Your Mind, Change Your Brain.Now there's no doubt that the brain is plastic, able to rewire itself in response to damage or training, and that it's more so than was generally believed, say, 20 years ago. It's clearly an important and interesting field, but a little caution is warranted. Neuroplasticity can't fix everything.If the brain were infinitely plastic, brain damage would be no big deal.

Manatees in Florida are a battle hardened lot. A large proportion of the sluggish sea cows have injuries from boat strikes, which is something of an occupational hazard when you live in the heavily trafficked coastal waterways of the sunshine state. Indeed, lots of manatees have multiple scars from a lifetime of encounters with leisure craft, and boat strike is the biggest human cause of manatee deaths in that state.
