Enrique Iglesias might have had a heart attack because of his beloved, in reality the culprit are bacteria. Research published online in mBio®, indicates that stress, fear or over exertion may trigger these bacteria to cause a heart attack in vulnerable people. Hormones released during such events cause bacterial biofilm to disperse and rupture the plaque deposits into the bloodstream. This causes clogging of artery and restriction of blood flow and hence death.... Read more »

Researchers from the University of Oxford performed a meta-review based on clinical studies of mental illness. These included mental health problems, substance and alcohol abuse, dementia, autistic spectrum disorders, learning disability and childhood behavioural disorders. They found that most of these reduce life expectancy with 7 to 24 years, whereas heavy smoking reduces life expectancy with 8 to 10 years.... Read more »

An interview with Dr. Jan Van den Bulcke. He is an expert on X-ray computed tomography (CT) on wood, a technique that allows to see the inner structure of objects in 3D by irradiating them with X-rays. This technique has long been used in medicine and geology, but it was only recently applied in many other research fields, resulting in a tremendously fast evolution... Read more »

Current therapies of heavily injured muscles imply surgical removal of the scar tissue and transplantation of immature muscles cells. Unfortunately, the transplanted cells are often unable to survive after transfer into patients. Now scientists bypassed this problem by providing the damaged tissue only with a biological scaffold of Extracellular Matrix (ECM). The results are promising.... Read more »

The company Foc.us Labs has recently released a commercial tDCS headset directed towards video-gamers. The electrodes are placed on the gamer’s forehead so that the prefrontal cortex is targeted with 1-2 milliamps of current for 5-40 minutes. It improves performance, shows research. But is it really healthy?... Read more »

The origin of zebra stripes has long been a mystery: in over a century, scientists developed various hypotheses. Social factors, cooling mechanisms and camouflage against predators, were proposed as possible explanations. However, no striking evidence could support one particular theory, so the black and white striping in zebra was believed to remain a grey area.... Read more »
Growth of biomedical research simultaneously hinders and advances its development.
This week brought to the forefront two important pieces of news in the field of biomedical research. Bad news first – the future of biomedical research looks bleak if things are not going to change. Then the good news – depending on your views on science, this second bit could be either head-scratching or eye opening: Scientists in the Scripps Research Institute, following years of research, have been able to create a synthetic organism with an “artificial DNA”....

It was easy for Dodo's to perish since they were stuck in one place. But, some dodos travelled. Or were forced to travel anyway. As it goes with rare things, the rarer they get, the more of a collector’s item they become for the wealthy. ... Read more »
Maybe you have already heard about the magic effects of adding a ‘Medium’ size. It makes the ‘Small’ look a little too cheap to order. But the Medium size can do even more. If it is positioned strategically close to the Large option, it even makes the most expensive option look like a fairer deal.... Read more »

Moral judgement is often considered to be a fixed given, based on deep-seated ideas on what is morally right and morally wrong. But, however counter-intuitive it may seem: recent research shows that people react differently to moral dilemmas when presented in a foreign language than in their native language.... Read more »
The biotechnology tool known as CRISPR is making a big impact on medicine and other fields. It’s a collection of enzymes, originally found in the immune system of certain bacteria. One enzyme targets a particular gene, and its companion cuts out that section of DNA which may enable further changes.... Read more »
