The latest version of the American Psychiatric Association's (APA) controversial diagnostic code - "the DSM-5" - continues the check-list approach used in previous editions. To receive a specific diagnosis, a patient must exhibit a minimum number of symptoms in different categories. One problem - this implies someone either has a mental illness or they don't.To avoid missing people who ought to be diagnosed, over time the criteria for many conditions have expanded, and nowhere is this more appar........

The aim of the study was to provide evidence for the direct regulatory role of G6P on glycogen synthesis through the phosphorylation-mediated induction of GYS2 activity in the liver. The authors generated liver-specific glycogen synthase (GYS2) mutants containing Ala substitutions in the glucose-6-phosphate (G6P) phosphorylation regions. Compared to the wild type GYS2, targeted mutagenesis yielded several mutants which were insensitive to the phosphorylation-mediated activation of G6P. Specifi........ Read more »

Plant transformation is insertion of new genetic material to the plant’s body.

Scientists have found that asteroid and comet impact craters must be our priorities in finding the evidences of life on other planets.
In the present study, scientists have found complex organic material enclosed in glassy ejecta, produced during a meteor impact in western Tasmania about 800,000 years ago. The impact crated the 1.2-kilometre wide Darwin Crater, near Queenstown, Tasmania.
