October LITHOSPHERE delivered online

Recent studies in Lithosphere magazine reveal that vertical-axis rotations can significantly impact shortening estimates with potential errors of up to 14%. Additionally, researchers investigate non-Pratt component of oceanic isostasy, finding a dynamic response within the Earth's mantle necessary for equilibrium. Meanwhile, pulsed def...

Exercise does a body -- and a mind -- good

Research found that physical inactivity and negative body image increase the risk of mental health problems in adolescents, while sports participation lowers this risk. The study suggests that psychosocial factors, such as body image and social interaction, play a crucial role in explaining the link between exercise and mental health.

MSU-led projects to help war veterans

A pair of MSU-led projects aim to support Michigan National Guard members and their families by studying resiliency in military families and training mental health counselors to work with them. The projects are expected to help the military improve reintegration efforts and prevention and treatment programs.

Cellular eavesdropping made easy

A new approach devised by EMBL scientists enables the distinction of proteins secreted by cells from those in their food, allowing measurement of secretion changes over time. This method has opened new avenues for drug and biomarker screening, as well as studying cell responses to drugs and 3D growth conditions.

JCI early table of contents for September 24, 2012

Researchers at University of California, Berkeley report that epithelial cells in cornea express small antimicrobial peptides to defend against bacterial infections. High levels of prolactin block expression of kisspeptin, a protein hormone that induces secretion of GnRH, leading to infertility in women.

Embargoed news from Annals of Internal Medicine

Researchers found that brief, multicontact behavioral counseling interventions delivered by primary care physicians reduced hospital stays for adults with risky drinking. The campaign 'Tips from Former Smokers' successfully encouraged smokers to quit, with calls to the toll-free quit line more than doubling during the 12-week campaign.

Life in the extreme

Two single-celled Archaea species, nearly identical genetically, respond differently to uranium toxicity, one by metabolizing it as energy, and the other by inducing a dormant state. These findings could teach us about mechanisms of adaptation to extreme environments and have implications for understanding antibiotic resistance.

Managing soil copper in crops irrigated with cattle footbath wastewater

Researchers found that alfalfa growth stops when soil copper sulfate levels exceed 500 ppm and beneficial bacterial activity declines above 50 ppm. Crops irrigated with cattle footbath wastewater can accumulate plant-available copper levels up to 63 ppm, posing potential harm to grazing livestock.

New CU-Boulder study clarifies diversity, distribution of cutthroat trout in Colorado

A novel genetic study led by CU-Boulder postdoctoral researcher Jessica Metcalf has clarified the native diversity and distribution of cutthroat trout in Colorado, revealing a single surviving population outside its native range. The study also confirmed the extinction of two previously unknown cutthroat strains, including one from the...
