Elevated levels of C-reactive protein, a marker of inflammatory disease, appear to be associated with increased risk of psychological distress and depression in the general population of adults in Denmark, according to a report published Online First by Archives of General Psychiatry, a JAMA Network publication.

Amazon deforestation brings loss of microbial communities
An international team of microbiologists led by Klaus Nüsslein of the University of Massachusetts Amherst has found that a troubling net loss in diversity among the microbial organisms responsible for a functioning ecosystem is accompanying deforestation in the Amazon rainforest.

Deforestation in the Amazon equals net losses of diversity for microbial communities
Research from an international team of microbiologists has revealed a new concern about deforestation in the Amazon rainforest -- a troubling net loss in the diversity among the microbial organisms responsible for a functioning ecosystem.

Fluctuating environment may have driven human evolution
A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.

Study examines overuse of ambulatory health care services in United States
An analysis of nationally representative survey data found significant improvement in the delivery of underused care, but more limited changes in the reduction of inappropriate care in ambulatory health care settings between 1998 and 2009, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.

Why some grasses evolved a more efficient photosynthesis and others didn't
Two groups, or clades, of grasses that once had a common ancestry diverged, ultimately leaving the PACMAD clade more predisposed to evolve a more efficient,

Bumblebees do best where there is less pavement and more floral diversity
Landscapes with large amounts of paved roads and impervious construction have lower numbers of ground-nesting bumblebees, which are important native pollinators, a study from The University of Texas at Austin and the University of California, Berkeley shows.

Enzyme accelerates malignant stem cell cloning in chronic myeloid leukemia
An international team, headed by researchers at the University of California, San Diego School of Medicine, has identified a key enzyme in the reprogramming process that promotes malignant stem cell cloning and the growth of chronic myeloid leukemia, a cancer of the blood and marrow that experts say is increasing in prevalence.

Liquid crystal research, future applications advance
Contributing geometric and topological analyses of micro-materials, University of Massachusetts Amherst mathematician Robert Kusner aided experimental physicists at the University of Colorado by successfully explaining the observed

Mount Sinai survey shows that nearly 1 in 3 children with food allergies experience bullying
Nearly a third of children diagnosed with food allergies who participated in a recent study are bullied, according to researchers at the Icahn School of Medicine at Mount Sinai.

Children with chronic conditions increasingly use available resources in children's hospitals
Children with chronic conditions increasingly used more resources in a group of children's hospitals compared with patients without a chronic condition, according to a report that analyzed data from 28 US children's hospitals between 2004 and 2009, and is being published Online First by Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication.

Big transfusions add risk for heart attack patients with anemia
A new study published in the Archives of Internal Medicine finds that while blood transfusions for heart attack patients with anemia are commonly performed in emergency rooms, the practice can increase the risk of death when the transfusions are too extensive.

Study: Blood transfusion associated with increased risk of death for patients with heart attack
A meta-analysis of 10 studies suggests that receipt of a blood transfusion among patients with myocardial infarction (heart attack) was associated with increased all-cause mortality compared with not receiving a blood transfusion during heart attack, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.

Eyes may provide a look into multiple sclerosis progression
New research suggests that thinning of a layer of the retina in the eyes may show how fast multiple sclerosis is progressing in people with the disease.

Ultrasound diagnoses appendicitis without X-rays
Children suspected of having appendicitis are more likely to receive CT scans, which involve radiation, if they are evaluated at a general hospital, a new study by Washington University School of Medicine in St.

NYU biologists identify proteins vital to chromosome segregation
NYU biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division.
