Eating garbage: Bacteria for bioremediation

A 150-foot-high garbage dump in Colombia, South America, may have new life as a public park. Researchers at the University of Illinois have demonstrated that bacteria found in the dump can be used to neutralize the contaminants in the soil.

Economic policies in isolation won't lead to growth in Europe

A study led by Dr. Bryony Hoskins at the University of Southampton for the European Commission has warned of the dangers of concentrating solely on economic policies to create growth in European countries. The report Participatory Citizenship in the European Union funded by a €274,996 grant from the EC examines how and to what extent, people in Europe actively take part in society, communities...

Economist shows the value of moving back with mom and dad

Though many may dread the idea, young adults who move back home with mom and dad after a job loss may benefit from it more than they realize. Research published in the Journal of Political Economy finds that returning to the nest can be valuable insurance in a tough labor market, serving as a short-term safety net while also keeping long-term earnings from being stunted by a job loss.

EEG test to identify autism in children

New research published in BioMed Central's open access journal BMC Medicine demonstrates that EEG can distinguish between children with autism and neurotypical controls. Autistic children showed a reduction in short range connectivity indicating poor function of local brain networks, especially in the left hemisphere regions responsible for language. However these children had increased...

Elderly diabetics have fewer bouts of hypoglycemia at night with new insulin

A new variety of long-lasting insulin, called insulin degludec, lowers the risk of nighttime low blood sugar in elderly diabetic adults compared with insulin glargine, a systematic review of diabetes studies has found. The meta-analysis of phase 3 clinical trials will be presented Monday at the Endocrine Society's 94th Annual Meeting in Houston.

Electronic data methods research seeks to build a 'learning health care system'

Researchers participate in the Electronic Data Methods (EDM) Forum to maximize shared experiences and learning for using electronic clinical data to improve medical care and making informed health decisions. A July supplement to Medical Care is a special "EDM Forum" issue, highlights key issues researchers are facing, and innovative approaches that have been developed to build the infrastructure...

Exercise, even mild physical activity, may reduce breast cancer risk

A new analysis has found that physical activity - either mild or intense and before or after menopause - may reduce breast cancer risk, but substantial weight gain may negate these benefits. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the findings indicate that women can reduce their breast cancer risk by exercising and maintaining their weight.

Gene expression test identifies low-risk thyroid nodules

A new test can be used to identify low-risk thyroid nodules, reducing unnecessary surgeries for people with thyroid nodules that have indeterminate results after biopsy. The results of the multi-center trial, which includes researchers from the Perelman School of Medicine at the University of Pennsylvania, appear online in the New England Journal of Medicine.

Genetic heart diseases may be responsible for unexplained stillbirths

Genetic researchers have made an important step towards resolving the mystery of the causes of intrauterine fetal demise, or stillbirth, where a baby dies in the womb after the 14th week of gestation. Scientists from Italy, Germany, and the US have found that up to eight percent of such unexplained deaths may be caused by specific genetic heart conditions.

Greenland ice may exaggerate magnitude of 13,000-year-old deep freeze

Ice samples pulled from nearly a mile below the surface of Greenland glaciers have long served as a historical thermometer, adding temperature data to studies of the local conditions up to the Northern Hemisphere's climate. But the method -- comparing the ratio of oxygen isotopes buried as snow fell over millennia -- may not be such a straightforward indicator of air temperature.

Hormonal treatment associated with better test performance after stroke

Stroke patients treated who received hormonal treatment, combined with rehabilitation, performed better on functioning and reasoning tests than patients who received rehabilitative therapy alone, a new clinical study from Italy shows. The results will be presented Monday at the Endocrine Society's 94th Annual Meeting in Houston.

How bacteria change movement direction in response to oxygen: Molecular interactions unravelled

How single cell organisms like bacteria manage to react to their environment is not yet completely understood. A research team has gained new insights into the molecular interactions during aerotaxis of Bacillus subtilis, i.e., the dependence of the movement direction on the oxygen concentration in the environment. The research team investigated the conformational changes within the protein HemAT.

JCI early table of contents for June 25, 2012

This release contains summaries, links to PDFs, and contact information for the following newsworthy papers to be published online, June 25, 2012, in the JCI: The skinny on what makes us fat, Inflammatory bacterial deposits remain after antibiotic treatment, Oxidative stress fuels Trypanosoma cruzi infection in mice, Keeping the beat: regulating the cardiac conduction system, and more.

Lead poisoning blocks recovery of California condor population

A comprehensive study led by environmental toxicologists at UC Santa Cruz shows that California condors are continually exposed to harmful levels of lead, the principal source of that lead is ammunition, and lead poisoning from ammunition is preventing the recovery of the condor population.

Low vitamin D levels linked to weight gain in some older women

Older women with insufficient levels of Vitamin D gained more weight than those with sufficient levels of the vitamin, according to a new study funded by the National Institutes of Health and published online today in the Journal of Women's Health. The study of more than 4,600 women ages 65 and older found that over nearly five years, those with insufficient levels of Vitamin D in their blood...
