Study finds new links between number of duplicated genes and adaptation
Liken it to a case of where two genes are better than one. Scientists have found a class of genes, called small-scale duplication genes, or SSDs, that are important for adapting to novel environments and surviving environmental changes.

New research shows how pathogenic E. coli O157:H7 binds to fresh vegetables
Between 20-30 percent of food-poisoning outbreaks linked to disease-causing strains of the bacterium Escherichia coli are caused by people eating contaminated vegetables. Research presented today at the Society for General Microbiology's Annual Meeting in Liverpool shows that the disease-causing E. coli O157:H7 interacts directly with plant cells allowing it to anchor to the surface of a plant, where it can multiply.

Brain changes are associated with casual marijuana use in young adults
The size and shape of two brain regions involved in emotion and motivation may differ in young adults who smoke marijuana at least once a week, according to a study published April 16 in the Journal of Neuroscience. The findings suggest that recreational marijuana use may lead to previously unidentified brain changes, and highlight the importance of research aimed at understanding the long-term effects of low to moderate marijuana use on the brain.

Prolonged and heavy bleeding during menopause is common
Women going through menopause most likely think of it as the time for an end to predictable monthly periods. Researchers at the University of Michigan say it's normal, however, for the majority of them to experience an increase in the amount and duration of bleeding episodes, which may occur at various times throughout the menopausal transition.

Microbes can be highly efficient, versatile and sophisticated manufacturing tools, and have the potential to form the basis of a vibrant economic sector. In order to take full advantage of the opportunity microbial-based industry can offer, though, educators need to rethink how future microbiologists are trained, according to a report by the American Academy of Microbiology.

Casual marijuana use linked to brain abnormalities in students
Young adults who used marijuana only recreationally showed significant abnormalities in two key brain regions that that are important in emotion and motivation, scientists report. This is the first study to show casual use of marijuana is related to major brain changes. It showed the degree of brain abnormalities in these regions is directly related to the number of joints a person smoked per week.

Mouse model would have predicted toxicity of drug that killed 5 in 1993 clinical trial
Over 20 years after the fatal fialuridine trial, a study published this week in PLOS Medicine demonstrates that mice with humanized livers recapitulate the drug's toxicity. The work suggests that this mouse model should be added to the repertoire of tools used in preclinical screening of drugs for liver toxicity before they are given to human participants in clinical trials.
