As increasingly hot and severe wildfires scorch the West, some lichen communities integral to conifer forests aren't returning, even years after the flames have been extinguished, according to a study from scientists at the University of California, Davis.
Inducing labor in healthy women at 39 weeks into their pregnancy reduces the need for cesarean section and is at least as safe for mother and baby as waiting for spontaneous labor. Choosing to induce could also reduce the risk that mothers will develop preeclampsia and that newborns will need respiratory support after delivery, according to a study publishing online in the New England Journal of Medicine on August 8.
ANN ARBOR, Mich. - New Medicaid rules in several states mean low-income people will have to work, or prove they're too unhealthy to work, to receive health coverage. Other states want permission to require the same, which could affect millions of Americans living in or near poverty.
Before these requirements get into full gear, a team of University of Michigan researchers is offering specific recommendations to help states ensure that work requirements don't harm the health of people enrolled in Medicaid.
San Antonio, TX (August 8, 2018) - A new study at Texas Biomedical Research Institute is shedding light on the role of specific proteins that trigger a mechanism allowing Ebola virus to enter cells to establish replication. The work, published in a supplement to The Journal of Infectious Diseases, was led by Staff Scientist Olena Shtanko, Ph.D., in Texas Biomed's Biosafety Level 4 laboratory. The BSL4 is a high-containment facility that houses research on diseases for which there are no approved vaccines or cures.
Some relationships can be complicated. Take the one between sweet potato crops and soil nitrogen, for example.
Too little nitrogen and sweet potato plants don't grow well and have low yields. Too much nitrogen, however, boosts the growth of leaves and branches at the expense of storage roots. That also leads to low yields.
"Carefully managing soil nitrogen levels is essential to obtain high yields from sweet potato crops," says Adalton Fernandes, an agronomist at the Center for Tropical Roots and Starches at São Paulo State University in Brazil.
Army researchers have designed a computer model that more effectively calculates the behavior of atmospheric turbulence in complex environments, including cities, forests, deserts and mountainous regions.
This new technology could allow Soldiers to predict weather patterns sooner using the computers at hand and more effectively assess flight conditions for aerial vehicles on the battlefield.
Turbulence may be invisible to the naked eye, it is always present around us in the air in the form of chaotic changes in velocity and pressure.
COLUMBIA, Mo. - Osteoporosis, decreased physical activity and weight gain are serious health concerns for postmenopausal women. Researchers from the University of Missouri now have discovered through a new animal study that soy protein found in food might counter the negative effects of menopause on bone and metabolic health. Moreover, the researchers believe that soy protein might also have positive impacts on bone strength for women who have not yet reached menopause.
The Icelandic Sagas tell of Erik the Red: exiled for murder in the late 10th century he fled to southwest Greenland, establishing its first Norse settlement.
The colony took root, and by the mid-12th century there were two major settlements with a population of thousands. Greenland even gained its own bishop.
By the end of the 15th century, however, the Norse of Greenland had vanished - leaving only abandoned ruins and an enduring mystery.
New research shows that humans "see" the actions of others not quite as they really are, but slightly distorted by their expectations.
Published today (8 August) in Proceedings of the Royal Society B, the study could explain why people get others' actions so wrong and see ambiguous behaviour as meaningful, according to authors from the University of Plymouth School of Psychology.
The study, funded by the Economic and Social Research Council, saw 85 participants watch an actor reach for an object with a straight or arched trajectory on a touch screen.
