Usually, when I post about a scientific paper, the focus is on its methodology and interpreting its conclusions into real world applications. This time, we’re going to do something a little different and use an oft cited paper on the plausibility of warp drive propulsion to build a theoretical model of our own. You see, [...]...

With banks being bailed out all over the place these days, many people are asking themselves why those in charge get paid such high salaries. Are CEOs really worth their million pound bonuses? Not according to Venkat Venkatasubramanian, who has calculated that US chief executives get paid nearly 130 times what they should.
As a professor [...]... Read more »

Which physical characteristics make for attraction? Many popular science reports evoke evolutionary psychology arguments as explanations of why modern humans supposedly respond to these attractiveness cues, but often times these reports fail to consider conflicting data realities as well as the many subtle limitations that are generally involved in research......

Notion of pre-competitive collaboration has been in under experiment steadily for quite sometime now. Notable examples are the Airbus consortium of European aircraft manufacturers, the Sematech consortium of US semiconductor manufacturers, banks working together to launch Visa and Mastercard, our recent moon lust and many more. But this was never a case for pharmaceutical industry until now which is now lowering industry firewalls to shift funding and focus from early- to late-stage projects by ........ Read more »

Recently I finished writing an article with child depression researcher Dr. Maria Kovacs about the concept of prodromal processes in child and adolescent depression.

The title of this post should not come as a surprise to readers of virology blog – it was shown in 1974 that zinc could interfere with replication of rhinoviruses (see “Zinc and the common cold“). I am referring to the result of my first experiment to study the mechanism of zinc inhibition – something I promised I would document on these pages.

One of the hottest searches we see all the time is for more information on CNVs, or copy number variations. These intriguing structural variants in our genomes explain a lot of the reason that SNP hunting for complex diseases like schizophrenia and autism weren’t able to elucidate the problems as most people expected. These spectrum sorts of conditions were just not going to turn out as straightforward as the sickle-cell variation or the cystic fibrosis stories.

The Journal of Experimental Biology has published an interesting paper about some unique features in sprinters: longer toes and shorter ankle joints.

The research and development of biofuels is beginning to attract investment from large international companies, including those traditionally associated with their fossil fuel predecessors.
A series of news articles published in Nature evaluate recent shifts in interest and investment in jatropha and algae as biofuel feedstocks, as well as techniques to produce cellulosic ethanol and liquid fuel directly from biomass (content requires subscription or payment).

People are no more fearful of crossing a street with a young male skinhead in it than they are a street with a smartly dressed woman present, unless, that is, a CCTV camera is overhead. The new finding appears to undermine one of the key justifications for Britain's network of 4.2 million surveillance cameras: that they provide reassurance to the public. It seems that the sight of a CCTV camera can have the opposite effect, cueing the perception of a threat. Dave Williams and Jobuda Ahmed presen........ Read more »

The idea that the kachina cult was not an indigenous development among the Pueblos but was instead introduced from the south seems to have originated with a 1974 article by Polly and Curtis Schaafsma.

One of my favorite cartoons as a child was "Speed Racer." It featured an all-American boy (first name, "Speed," last name, "Racer") engaging in that most American of pastimes: driving fast cars. Except that "Speed Racer" wasn't really American; it was made in Japan, and the original Japanese voices were crudely overdubbed in English. Perhaps I can be excused for not noticing the Japanese origins of the show -- I was only 10 years old. Even now, as an ........ Read more »
