Although prostate cancer will affect over 23,000 U.S. men next year, the individual genes that initiate prostate cancer formation are poorly understood, but finding an enzyme that regulates this process could provide excellent new prevention approaches for the malignancy.

Sirtuin enzymes have been implicated in neurodegeneration, obesity, heart disease, and cancer and a new paper in The American Journal of Pathology finds that the loss of SIRT1 drives the formation of early prostate cancer (prostatic intraepithelial neoplasia) in mouse models of the disease. 

Over the past decade, ocean acidification has started to receive recognition outside science, though primarily as another weapon in the 'carbon dioxide' culture war on the modern world, similar to methane being discussed this year.

Politics aside, it is a vital area for study and a new article outlines three major challenges to understanding the real issues and effects: It needs to expand from single to multiple drivers, from single species to communities and ecosystems, and from evaluating acclimation to understanding adaptation.  

If you think of quantum physics in terms of information about a system, it is a lot less complicated, according to a new paper. In that context, features of the quantum world previously considered distinct  -  wave-particle duality and the quantum uncertainty principle - are different manifestations of the same thing.

Cockroaches are most often though of as infecting human homes but a new species and a new subspecies discovered in China prefer to live a hermit life, drilling logs far away from crowds and houses. 

Televisiom programs such as "The Dr. Oz Show" and "The Doctors" have attracted massive followings, primarily due to having charismatic hosts who clearly mean well, coupled with a public desire to know the science basis for how we function.

But in the quest to have new content so often each week, the perception among the science community is that they will run with any claims about the latest health miracle or scary chemical. That doesn't help the public, it just promotes suspect alternatives to medicine or an anti-science mentality among the people who would most benefit from an evidence basis for decision-making.

A terrestrial laser scanning technique that allows the structure of vegetation to be 3D-mapped to the millimeter is more accurate in determining the biomass of trees and carbon stocks in forests than current methods, according to a paper in Methods in Ecology and Evolution. 

The study authors believe it could be used in monitoring carbon stocks for climate policy. Both above-ground biomass and carbon stocks are important details for UN-REDD, the United Nations initiative on Reducing Emissions from Deforestation and forest Degradation that is striving to keep the destruction of forests in check and thereby preserve the uptake of carbon by trees.
