As body mass index increases, blood pressure may as well

Jue, 08/16/2018 - 22:00
Body mass index is positively associated with blood pressure, according to the ongoing study of 1.7 million Chinese men and women being conducted by researchers at the Yale Center for Outcomes Research and Evaluation (CORE) and in China. These findings appear in the Aug. 17 issue of JAMA Network Open.

Particulate pollution's impact varies greatly depending on where it originated

Jue, 08/16/2018 - 22:00
Aerosols are tiny particles that are spewed into the atmosphere by human activities, including burning coal and wood. They have negative effects on air quality -- damaging human health and agricultural productivity. New work from Carnegie's Geeta Persad and Ken Caldeira demonstrates that the impact these fine particles have on the climate varies greatly depending on where they were released.

Coal miners at growing risk of developing debilitating, deadly lung fibrosis

Jue, 08/16/2018 - 22:00
The number of cases of progressive massive fibrosis (PMF) among US coal miners has risen during the past two decades, even as the number of coal miners has declined, according to new research published online in the Annals of the American Thoracic Society.

Statins associated with improvement of rare lung disease

Mié, 08/15/2018 - 22:00
Researchers have found that cholesterol-lowering statins may improve the conditions of people with a rare lung disease called autoimmune pulmonary alveolar proteinosis. The research also suggested that two new tests could help diagnose the condition.

MSU plant sciences faculty part of international discovery in wheat genome sequence

Mié, 08/15/2018 - 22:00
Hikmet Budak, Winifred Asbjornson Plant Sciences Chair, is one of 200 international scientists who co-published an article this week detailing the description of the genome of bread wheat. The implications of the publication include greater food security.

Scientists discover why some people with brain markers of Alzheimer's have no dementia

Mié, 08/15/2018 - 22:00
A new study from The University of Texas Medical Branch at Galveston has uncovered why some people that have brain markers of Alzheimer's never develop the classic dementia that others do. The study is now available in the Journal of Alzheimer's Disease.

Microfossils, possibly world's oldest, had biological characteristics

Mié, 08/15/2018 - 22:00
Scientists have confirmed that the 3.4 billion year old Strelley Pool microfossils had chemical characteristics similar to modern bacteria. This all but confirms their biological origin and ranks them amongst the world's oldest microfossils. The work is presented at the Goldschmidt geochemistry conference in Boston, with simultaneous publication in the peer-reviewed journal Geochemical Perspectives Letters.

Blood test could detect kidney cancer up to five years prior to clinical diagnosis

Mié, 08/15/2018 - 22:00
A team of investigators led by Beth Israel Deaconess Medical Center (BIDMC) medical oncologist Rupal Bhatt, M.D., Ph.D., has demonstrated that a molecule called KIM-1, a protein present in the blood of some patients with renal cell carcinoma is present at elevated levels at the time of diagnosis, can also serve as a tool to predict the disease's onset up to five years prior to diagnosis.

Quantum material is promising 'ion conductor' for research, new technologies
