As I interact with colleagues I sense an incredible, almost exuberant, level of excitement and anticipation for the DSM-V. “It will change psychiatry”, “it will answer the questions”, “it will abandon categories”, etc, etc, etc. The expectations are so great and in so many directions, that I can’t help but to think that the DSM-V [...]...

In May, I reported that Russian scientists at the Institute of Theoretical and Experimental Biophysics in Pushchino and the Institute of High-Energy Physics in Protvino, had investigated the chronic effects of the radiation to which we are exposed every time we fly in high altitude aircraft. They wanted to know if any putative damage [...]Post from: Sciencebase Science Blog... Read more »

Common quails (Coturnix coturnix) breed in Spanish wheat and barley fields; when harvesters arrive, destroy their habitat as if you cut the forest of a woodpecker. Harvesting is not simultaneous through Spain and the authors of this paper already suspected from long ago that quails respond to this ecological threat migrating from early towards later fields. But…. How to test this hypothesis? Domingo Rodríguez-Teijeiro and his team have confronted the issue with three information sources: ring........ Read more »

Unraveling and disentangling homology and convergence is one of the most fascinating endeavors in biology. Homology indicates common origin and maintenance, and is often taken as evidence for importance: ancient features are thought to be maintained because they are too useful to dispose of during evolution. In contrast, convergence, is the separate invention of similar features or functions during evolution. Convergence is taken as evidence for an element of predictability in evolution. For........

I was fascinated by Bonnie Brasler's TED talk on Quorum-Sensing, and being a chemist I wanted to know more about the molecules involved. She did put up a slide with structures during the talk, but I wanted more so I did a search on PubMed and found this Perspective written by Brassler and Michael Federle. My only experience with the notion of a “quorum” is our Faculty Assembly where we sometimes have difficulty achieving a quorum. In order for the meeting to be “official” and for any........

Macrophage engulfing Bacillus Calmette-Guérin
The oldest vaccine, as everyone knows, is the smallpox vaccine. 1 Another old vaccine (though not in the same class as smallpox vaccine) is the tuberculosis vaccine, Bacillus Calmette-Guérin (BCG), developed in 1921.
There’s all kinds of interesting stuff about BCG. It’s a live vaccine, meaning that the vaccine is live [...]... Read more »

“Science is inevitably biased to some extent,” says Dr Daniele Fanelli, “because it’s made by human beings.” One might easily dismiss this claim as unfounded, but Fanelli has the numbers to back it up. His recent research paper combined over 20 previous studies on scientific misconduct, and found that nearly 2% of scientists admit to [...]... Read more »

Striking similarity between biological systems and computing paradigms is not new, and in past there have been several attempts to draw an analogy between systems biology and computing systems. For interested readers I will recommend my last post which examine how systems biology of human can be describes as a grid of super-computers. Over the time researchers have developed several bio-inspired fault-tolerance methods to support fault detection and removal in both hardware and softwares systems........ Read more »

Using metaphors to explain complex scientific phenomenon is not new, and indeed metaphors are widely used in science. In biology tree of life is utilized as a metaphor for common descent in the evolutionary sense, which occasionally represented as a web or a net of life. Many scientists suggest that concept of tree of life is misleading and there is no strong evidence that the tree of life is a reality. Similarly in genomics the genome as the book of life and selfish gene are commonly ........ Read more »

In what sounds like a rather unpleasant experience, participants who were given false feedback that they were blushing, subsequently blushed more and anticipated being negatively judged by the people they were conversing with. The finding could help explain why some shy people fall into a vicious of circle of fearing blushing, feeling that they are blushing more than they are, and ultimately fearing social situations because of it.Corine Dijk and colleagues recruited one hundred undergrads who'd........

This is another paper that was recommended to me by Peter Leong who is teaching a course in Second Life this summer for the College of Education at the University of Hawaii. We are trying to better understand how we might build engaging learning spaces in Second Life.Reading this paper I started wondering what proportion of the population went to museums. Superficially I imagine computer games and films/tv to be far more frequently consumed by the general population, although since having chil........ Read more »

Cardinal Cormack Murphy O'Connor caused a stir last month with his claim that atheists are not fully human because they don't have a sense of transcendental. Now, atheists mostly aren't transcendental almost by definition - the word refers to a belief in something for which there is no evidence.But do atheists also lack more common human emotions, like a sense of awe and wonder? After all, these emotions are also irrational - they depend upon imbuing a quality to objects that isn't intrinsic to ........ Read more »

There never was a single "depression gene", and those patting themselves on the back because of the ceremonial defenestration of that straw man are fooling themselves.Yes, a new meta-analysis in JAMA (Risch et al., 2009) found that a variant of the serotonin transporter gene (the 5-HTTLPR polymorphic region) is not linked to an increased risk of depression, either alone or in combination with stressful life events. This study examined 14 prior papers, including the now-maligned article by Caspi ........ Read more »

If you've been following my blog a long time, you may remember a post on stellar evolution that was responding to some rather silly claims made by some Creationists. One of the claims was that the universe must be young, because we see young, massive stars where there's no gas and dust to form them. The example he used was near the galactic center. My response then (and still is) that this makes the rather ignorant assumption that stars stay where they're formed.The center of the galaxy is a ver........ Read more »
