The traditional view in biology is that ecology shapes evolution. The environment defines a template and the process of evolution by natural selection shapes organisms to fit that template. Some  recent research suggest, however, that evolutionary processes reciprocate by influencing ecology in turn.

Now a team of biologists presents new evidence that ecology and evolution are indeed reciprocally interacting processes, presenting a fundamental shift in our understanding of the relationship between evolution and ecology. Study results appear this week in the online early edition of the Proceedings of the National Academy of Sciences.

 No vaccine currently exists for West Nile Virus, but a new therapeutic made from tobacco plants has been shown to arrest the infection, according to research conducted by Arizona State University scientists. The study, published this week in PNAS,  is the first to demonstrate a plant-derived treatment to successfully combat West Nile virus after exposure and infection.

"The goal of this research was twofold," said Arizona State University scientist Qiang Chen. "First, we wanted to show proof-of- concept, demonstrating that plant-made antibodies can work as effective post-exposure therapeutics. Secondly, we've sought to develop a therapeutic which can be made inexpensively so that the health care systems in developing countries can afford it."

Extended use of nicotine patches – 24 weeks versus the standard eight weeks recommended by manufacturers – boosts the number of smokers who maintain their cigarette abstinence and helps more of those who backslide into the habit while wearing the patch, according to new a study published in the Annals of Internal Medicine.

A palm-sized device invented at Cornell that uses water surface tension as an adhesive bond just might make walking on walls possible for humans. The rapid adhesion mechanism could lead to such applications as shoes or gloves that stick and unstick to walls, or Post-it-like notes that can bear loads, researchers say.

The device is the result of inspiration drawn from a beetle native to Florida, which can adhere to a leaf with a force 100 times its own weight, yet also instantly unstick itself. Research behind the device is published in the Proceedings of the National Academy of Sciences.

According to a new report in the Archives of General Psychiatry, individuals at extremely high risk of developing psychosis appear less likely to develop psychotic disorders following a 12-week course of fish oil capsules containing long-chain omega-3 polyunsaturated fatty acids.

Researchers conducted a randomized, double-blind, placebo-controlled clinical trial of their effect on the risk of progression to psychosis in 81 individuals at ultra–high risk. These individuals either had mild psychotic symptoms, transient psychosis or a family history of psychotic disorders plus a decrease in functioning. These criteria identify individuals whose risk of becoming psychotic may be as high as 40 percent in a 12-month period.

Last Friday I was in Pisa, at the Scuola Normale Superiore (see picture), where italian members of the CMS Collaboration gathered for two days to discuss the status of their studies, exchange ideas, and try to coalesce common analysis efforts.

     I have been following with interest the columns and blogs related to climate change, most recently from Patrick Lockerby, who agrees with the evidence for human-caused global warming, and Karen Barnes, who comments on Jesse Ventura’s conspiracy theory.  Perhaps thoughttul readers of Scientific Blogging will be interested in seeing the actual data that supports global warming. Here is a NOAA website that succinctly summarizes the main lines of evidence.
