Persistent Pollutant May Promote Obesity http://www.sciencedaily.com/releases/2008/12/081201081921.htm A persistent pollutant, tributyltin, has effects on gene activity in a wide range of animal species at concentrations of parts per billion. Tributyl tin and its chemical relatives bind to nuclear receptors that in turn activate genes influencing the formation of fat storage cells. This and other evidence suggests a possible role for tributyl tin in the obesity epidemic. The compound has been shown to affect gene activity at extremely low concentrations.

This could be done with 14C tests of air samples, but the same types of measurements can also be carried out on plants that have absorbed CO2. To that end one would need plant material that is known to come from a specific region and also know which year it grew in.

But how does this translate to the evolution of species? A new article reviews an aspect of the natural world that, like survival of the fittest individual, is explained by natural selection: namely, mutualism -- an interaction between species that has benefits for both. The work shows that some species of butterfly that live alongside one another have evolved in ways that, surprisingly, benefit both species.

Chemists have now identified the genetic sequence behind gray mold's killer arsenal. The scientists report that deletion of a single, mastermind gene from gray mold's DNA shuts down its ability to produce toxins that kill cells in more than 200 species of garden and ornamental plants.

Scientist have now developed a method of measuring soil quality to assure an adequate amount of soil organic matter, called the CQESTR model.

These sentiments were found in a public survey by the Wildlife Conservation Society at a national conference on restoring bison populations in the North America.

Changes in their direction or velocity indicate variations in the materials through which they pass. Geophysicists have now been able to show in a model exactly what happens at zones where crustal plates subduct below one another.

Non-Target Insects Affected More By Insecticides Than By Crops Engineered To Make Insect-specific Toxins http://www.sciencedaily.com/releases/2008/11/081129151957.htm Non-target insects are probably affected more by conventional insecticides than by crops that contain genes from the soil bacterium Bacillus thuringiensis (Bt), according to a new article. Bt crops such as maize and cotton are genetically engineered to produce insect-specific toxins.

The principal function of the antimicrobial peptides produced by the insect immune system is to prevent the resurgence of bacteria resistant to the host's constitutive defenses, which will consequently reduce the emergence of resistant bacteria.
