The research is clear: Adolescents tend to fare better -- academically and behaviorally -- when they live with both biological parents. But when their parents frequently argue, young adults are significantly more likely to binge drink than other teenagers. They also tend to smoke, and their poor school grades are similar to those of their peers who don't have both biological parents at home.

Non-invasive imaging can measure how well patients with the most common form of breast cancer -- estrogen receptor positive type -- respond to standard aromatase inhibitor therapy after only two weeks and shows similar findings that more invasive needle sampling identifies, according to new research.

Agricultural engineers have developed the erosion control industry's first cotton hydromulch "spray-on blanket." Hydromulch is the bright-green mulch used in spray-on slurries that cover bare lands at construction sites and roadside projects, to prevent erosion until vegetation can be established. In the past, hydromulches were made mostly from wood and paper byproducts.

Mice carrying a "humanized version" of a gene believed to influence speech and language may not actually talk, but they nonetheless do have a lot to say about our evolutionary past, according to a new report.

Chorus waves, a type of electromagnetic emission generated by electrons in Earth's radiation belt, play an important role in both accelerating and removing the energetic radiation belt electrons that can disrupt satellite electronics and disturb communications with ground-based operators.

Theta oscillations are a type of brain rhythm that orchestrates neuronal activity in the hippocampus, a brain area critical for the formation of new memories. For several decades these oscillations were believed to be "in sync" across the hippocampus, timing the firing of neurons like a sort of central pacemaker. Researchers show that instead of being in sync, theta oscillations sweep along the length of the hippocampus as traveling waves.

People like to believe their actions are driven by their own free will and are not unduly affected by other people. Research, though, shows the way we act is often subconsciously influenced by what we believe to be ‘normal’ behavior. A new research project is about to take this finding to the next level by investigating whether it is possible to nudge individual behavior in a socially-desirable direction, simply by telling people what others are doing.

People with type 1 diabetes who have already been successful in achieving recommended blood sugar goals can further benefit from using continuous glucose monitoring (CGM) devices, according to results of a major multi-center clinical trial.

Current research suggests that Mycobacterium tuberculosis can evade the immune response. The related report by Rahman et al., "Compartmentalization of immune responses in human tuberculosis: few CD8+ effector T cells but elevated levels of FoxP3+ regulatory T cells in the granulomatous lesions," appears in the June 2009 issue of the American Journal of Pathology.

Intestinal permeability and an overgrowth of bacteria in the small intestine are both associated with non-alcoholic fatty liver disease, according to new findings.
