NASA's TESS helps astronomers study red-giant stars, examine a too-close planet

Tuesday November 19th, 2019 05:00:00 AM
Iowa State astronomers are part of an international team that has been analyzing data from NASA's TESS Mission. The astronomers describe their study of two red-giant stars -- older, 'retired' stars no longer burning hydrogen in their cores -- in a paper recently published by The Astrophysical Journal. The study details an interesting case of planetary evolution and demonstrates how star studies can be an important part of the mission's search for planets beyond our solar system.

Families of youth with autism face big barriers to care, gaps in services

BU and BMC find pediatric behavioral health care integration shows promise

Tuesday November 19th, 2019 05:00:00 AM
A new study published in Health Services Research and led by a Boston University School of Public Health (BUSPH) researcher finds that, in the first year and a half of the program, children with mental health diagnoses who were served by the TEAM UP sites went for more primary care visits than similar children served by nearby non-participating community health centers.

Study: Sepsis survivors require follow-up support

Tuesday November 19th, 2019 05:00:00 AM
Survivors of sepsis -- a life-threatening response to an infection -- have expressed a need for advocacy and follow-up support, according to a study authored by professors at the University of Tennessee, Knoxville, and the University of Tennessee Health Science Center in Memphis, and published in Dimensions of Critical Care Nursing.

E-meditation: A new tool for an ancient technique

Tuesday November 19th, 2019 05:00:00 AM
E-meditation combines meditation with a low-level electrical stimulation that activates areas of the brain associated with meditation. Previous studies have suggested the combination of meditation and brain stimulation leads to reduced stress. At the Joint Meeting of Neuromodulation, Medical University of South Carolina researchers reported results from a study conducted during a five-day meditation retreat. E-meditation enhanced practice in both novice and experienced meditators, who were able to self-administer stimulation during meditation with minimal assistance.

New danger for corals in warming oceans: Metal pollution

Tuesday November 19th, 2019 05:00:00 AM
Metal copper from agricultural runoff and marine paint leaching from boat hulls poses an emerging threat to soft coral sea fans in the waters around Puerto Rico.

New statistical model improves the predictive power of standardized test scores

Tuesday November 19th, 2019 05:00:00 AM
A study from Arizona State University and the University of Denver has validated a new statistical model that uses multiple standardized test scores over time to predict future academic performance. The dynamic measurement model accurately predicted academic performance decades in the future, and the predictions were three times better than current assessment methods. The model can be implemented immediately by using existing standardized test scores, such as annual assessments given to school children.

Demographic shifts, voter fears, and presidential voting

Tuesday November 19th, 2019 05:00:00 AM
New research from University of Pennsylvania, University of California, San Diego and Yale University shows Donald Trump's 2016 presidential campaign didn't benefit from voters' fears of immigrants in communities experiencing greater demographic change, a finding that surprised even the political scientists who conducted the study, including Penn political scientist Daniel J. Hopkins.

Tuesday November 19th, 2019 05:00:00 AM
NASA's Aqua satellite captured an image of newly formed Tropical Storm Sebastien, located northeast of the Leeward Islands in the Atlantic Ocean.

When do alcohol-dependent mothers parent harshly?

Tuesday November 19th, 2019 05:00:00 AM
While parents with substance use disorders are more likely to treat their children harshly, they don't do so all the time. What are the triggers? And how can substance-dependent mothers and their medical care providers predict difficulties across challenging parenting contexts?

Depression puts South African girls at higher risk of contracting HIV

Tuesday November 19th, 2019 05:00:00 AM
By the time they reach adulthood, one in four South African girls will have contracted the HIV virus. Experiencing depression puts these girls at even higher risk of infection, reveals analyses led by researchers at the University of California, Berkeley, The findings, which appear in the American Journal of Epidemiology, suggest that interventions targeted at improving mental health among adolescent girls may help stem the spread of HIV throughout sub-Saharan Africa.

Endangered whales react to environmental changes

Tuesday November 19th, 2019 05:00:00 AM
Some 'canaries' are 50 feet long, weigh 70 tons, and are nowhere near a coal mine. But the highly endangered North Atlantic right whale is sending the same kind of message about disruptive change in the environment by rapidly altering its use of important habitat areas off the New England coast.

Chronic opioid therapy can disrupt sleep, increase risk of sleep disorders

Tuesday November 19th, 2019 05:00:00 AM
Patients and medical providers should be aware that chronic opioid use can interfere with sleep by reducing sleep efficiency and increasing the risk of sleep-disordered breathing, according to a position statement from the American Academy of Sleep Medicine.

Technique identifies T cells primed for certain allergies or infections

A UC Davis study found that Lactobacillus plantarum bacteria rapidly repaired damaged gut lining (known as leaky gut) in monkeys infected with chronic simian immunodeficiency virus (SIV), an HIV-like virus. It linked chronically inflamed leaky gut to the loss of PPARα signaling and damage to mitochondria.
