So far the questions about whether nanoparticles are an environmental risk outnumber the answers, which is why the Duke scientists take the precaution of wearing clean-suits while dosing the boxes—no one’s sure what exposure to a high concentration of nanoparticles might do. Among the few things we do know about them are that they sail past the blood-brain barrier and can harm the nervous systems of some animals.... Read more »

Science blogging is increasingly gaining attraction among the masses. You can consider it as a form of bridge between the common people and the scientists resulting in more awareness of the problems and the solutions.
Paul Knoepfler, an associate professor at the University of California, Davis, School of Medicine, wrote,
“Savvy scientists must increasingly engage with blogs and social media. A new generation of young researchers has grown up with an ever-present Internet. Publishers........ Read more »

Newly published research shows that learning gets more difficult as we age, because we can’t push older memories out of our brains. Research conducted by neuroscientists at the Medical College of Georgia at Georgia Regents University demonstrated that mice with genetically modified brains, made to resemble those of humans in adulthood, had no difficulty forming the kind of strong synaptic connections responsible for learning....

You’ve probably heard of the scientific fraud conducted by Diederik Stapel, a former professor of social psychology in the Netherlands, which affected at least 55 publications. That he was a male faculty member isn’t that exceptional, according to a recent review of the United States Office of Research Integrity reports. It seems that men are overrepresented among scientists who commit fraud, on all academic levels.... Read more »

Before I moved to my current position in Maastricht, I had the great pleasure to work with Prof. Roland Grafström (check his pathway bioinformatics done with his then PhD Rebecca) and Prof. Bengt Fadeel at the Karolinska Institutet. During this year I part-time worked on ToxBank and part-time on nano-QSAR, and worked on semantics, predictive toxicology, and Open Data. This blog post is about the ToxBank work.

The frieze of the Parthenon forms a continuous band with scenes in relief that encircles the upper part of the cella, the main temple, within the outer colonnade.

Many health-conscious people have turned to raw foodism (also referred to as raw veganism or raw vegetarianism) in the past decade seeking a dietary plan that maximized the nutritional content of food. The core principle of the raw food diet was that cooking removes significant amounts of vitamins and minerals from food as well as enzymes that aid the body in digestion. It seemed like a health nut’s dream: consumers theoretically get the most vitamins and minerals from food with the least ........ Read more »

The Blue Whale (or Balaenoptera musculus) is big. Very big. In fact, as far as we know, it’s the largest animal to have ever lived on earth, growing to roughly 30m and weighing in at an impressive 175 tons. But could there be, or have been, a bigger whale?
A recent research article at PLOS ONE took on the challenge of answering this question.... Read more »

I’m holding in my hands two ball bearings, each about two centimeters in diameter. I propose to build a model of our cosmic environment here at the United Nations Headquarters in New York. The first sphere represents the sun. On this scale Earth will be two meters away, and much too small for you to see it. Mars, even smaller, will be another meter farther from the sun. On this scale, where should we place the second sphere, representing the closest star to our own solar system? On top of ........ Read more »

The conclusion came out of a study involving 4,000 participants who were matched with information about jobs and relationships. One of their main methods of measurement was to see what type of supervisory roles they had at work. The result showed that 1/4th of the group's "leadership variation traits" could be linked to genetics.

There are few, if any, species of organisms whose extinction we could all agree would be beneficial, however in the case of the pubic louse, we may have found an exception. Commonly known as “crabs,” the notorious pubic louse is disappearing.

Traditional colleges often struggle with limited space availability in popular (or even core curriculum) courses. Higher education costs in the U.S. have sky-rocketed in recent years.
