GSA Bulletin highlights: New research posted Aug. 8, 2011

Recent studies in California's Poison Lake chain, the Kyushu region of Japan, and the Cuyama River in California have revealed diverse volcanic formations and complex tectonic interactions. In California, research suggests that discrete batches of basalt erupted along a short normal fault zone, while in Japan, volcano-tectonic processe...

Stress can affect future offspring

A new study found that stress experienced by young female rats can affect their future offspring, causing behavior impairments. However, providing an enriched environment can ameliorate some of the negative effects. The study also showed that offspring raised in enriched environments can offset inherited effects.

Making a bee-line for the best rewards

Researchers found that bumblebees significantly reduced flight distances by learning and memorizing individual flower locations, prioritizing the shortest route. This innovative approach demonstrates that bees can solve complex routing problems without a sophisticated cognitive representation of space.

Referring doctors increasingly aware of deep brain stimulation therapy; more work remains

Researchers found that while deep brain stimulation has increased acceptance among referring physicians for Parkinson's disease and other movement disorders, only half of recommended patients are appropriate candidates for immediate therapy. This suggests that physicians have become more aware and accepting of the treatment, but may re...

Decoding infidelity linked to Type 2 diabetes

A team of researchers has discovered that a genetic mutation in the CDKAL1 gene can lead to misreading of specific parts of the insulin-producing gene, resulting in decreased insulin production and impaired cell function. This finding sheds light on the underlying mechanisms of Type 2 diabetes.

Researchers map pathway of infection for a common, potentially life-threatening respiratory virus

Researchers at the University of Toronto have identified a new treatment target for human respiratory syncytial virus (RSV), a common cause of severe lung infections and estimated 10% of colds. The study found that RSV interacts with healthy cells by binding to a molecule called nucleolin, allowing it to decrease or increase infection.

Researchers demonstrate green tea is effective in treating genetic disorder and types of tumors

Researchers at The Donald Danforth Plant Science Center have discovered that green tea polyphenols can control a deadly congenital disease by hijacking the ADP activation site. This finding has also been validated in two types of tumors, glioblastomas and tuberous sclerosis complex disorder, suggesting potential for drug development.

Nut-allergy sufferers face prejudice -- new study

A new study found that parents of nut-allergy sufferers often encounter hostility and scepticism from friends, family, and even restaurant staff, making it difficult to find safe environments for their children. The research highlights the need for better public education about the dangers of nut allergy.

Brand-conscious consumers take bad news to heart

A new study by University of Illinois marketing expert Tiffany Barnett White found that brand-conscious consumers view negative information about their beloved brands as a threat to their self-image. They defend the brand and re-write history to maintain a favorable self-evaluation, extending to multiple markets such as sports teams.

Women's quest for romance conflicts with scientific pursuits, study finds

Research by University at Buffalo professor Lora Park found that women who prioritize romantic goals over academic pursuits exhibit less interest in STEM fields. Women's socialization to be romantically desirable conflicts with traditional masculine scripts for intelligence and achievement, leading to decreased math and science interests.

Molecular delivery truck serves gene therapy cocktail

Researchers at UNC School of Medicine have devised a gene therapy cocktail that can treat some inherited diseases caused by misfolded proteins. The approach uses an adeno-associated virus (AAV) vector to deliver two payloads simultaneously: one disables the mutant protein and another provides a new gene to replace its activity.
