New Molecule May Aid In Production Of Biofuels And Fungi-resistant Pla
In a recent study published in the Journal of Biological Chemistry, scientists report on the discovery of a new molecule that is essential for degradation of the biopolymer chitin. This new molecule could eventually aid in the engineering of fungi-resistant plants and could also lead to the discovery of similar molecules that can be used in cellulose-based biofuel production. 86400 Moments: 24 Hours at Joshua Tree National Park

From the American Museum of Natural History. Better Predictors For Outcomes After Radical Prostatectomy
In the largest study of its kind to date, Mayo Clinic researchers report that prostate specific antigen (PSA) kinetics, both velocity and doubling time, can be used to predict disease progression and likelihood of death after radical prostatectomy surgery, suggesting that this could be used to guide treatment decisions. Study Links Progressive Aphasia Syndrome To Prion Gene
Most people with a rare type of dementia called primary progressive aphasia (PPA) have a specific combination of prion gene variants, a new study shows. The study is the first to link the prion protein gene to this disorder. The researchers also looked at the prion gene in people with Alzheimer's disease and amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease) and did not find any association with specific gene variants in those disorders.

According to conventional wisdom, old dogs and new tricks aren't a good match. But a new study of beagles finds that regular physical activity, mental stimulation, and a diet rich in antioxidants can help keep aging canine -- and perhaps human--brains in tip-top shape.
