Culture
A team of Colorado State University scientists, led by veterinary postdoctoral fellow Dr. Anna Fagre, has detected Zika virus RNA in free-ranging African bats. RNA, or ribonucleic acid, is a molecule that plays a central role in the function of genes.
According to Fagre, the new research is a first-ever in science. It also marks the first time scientists have published a study on the detection of Zika virus RNA in any free-ranging bat.
URBANA, Ill. -When pigs get hit with significant illnesses during key stages of pregnancy, their immune response may negatively affect developing piglets, making them less productive on the farm. New research from the University of Illinois shows that when those piglets - especially males - experience a second stressor in early life, they are at higher risk of neurodevelopmental and other neurological anomalies, putting them at an even greater disadvantage in production settings.
In a new study, University of Maine researchers found that culture helps humans adapt to their environment and overcome challenges better and faster than genetics.
After conducting an extensive review of the literature and evidence of long-term human evolution, scientists Tim Waring and Zach Wood concluded that humans are experiencing a "special evolutionary transition" in which the importance of culture, such as learned knowledge, practices and skills, is surpassing the value of genes as the primary driver of human evolution.
People of color are more than twice as likely to die after a traumatic brain injury as white people, according to a new retrospective review from Oregon Health & Science University.
The study published today in the journal Frontiers in Surgery.
Hydrogels are commonly used inside the body to help in tissue regeneration and drug delivery. However, once inside, they can be challenging to control for optimal use. A team of researchers in the Department of Biomedical Engineering at Texas A&M University is developing a new way to manipulate the gel -- by using light.
Tsukuba, Japan - It is estimated that during a heart attack, one billion cells in the heart are lost. In the wake of the heart attack, the lost tissue is replaced by scar tissue, which can lead to heart failure, arrhythmia and death. In a new study, researchers from the University of Tsukuba have shown how cells in the scar tissue can be converted to heart muscle cells, effectively regenerating the injured heart.
The Permian Basin, located in western Texas and southeastern New Mexico, is the largest oil- and gas-producing region in the U.S. The oilfield operations emit methane, but quantifying the greenhouse gas is difficult because of the large area and the fact that many sources are intermittent emitters. Now, researchers reporting in ACS' Environmental Science & Technology Letters have conducted an extensive airborne campaign with imaging spectrometers and identified large methane sources across this area.
Jack Tseng loves bone-crunching animals -- hyenas are his favorite -- so when paleontologist Joseph Peterson discovered fossilized dinosaur bones that had teeth marks from a juvenile Tyrannosaurus rex, Tseng decided to try to replicate the bite marks and measure how hard those kids could actually chomp down.
Last year, he and Peterson made a metal replica of a scimitar-shaped tooth of a 13-year-old juvie T. rex, mounted it on a mechanical testing frame commonly used in engineering and materials science, and tried to crack a cow legbone with it.
A large group of iconic fossils widely believed to shed light on the origins of many of Earth's animals and the communities they lived in may be hiding a secret.
Scientists, led by two from the University of Portsmouth, UK, are the first to model how exceptionally well preserved fossils that record the largest and most intense burst of evolution ever seen could have been moved by mudflows.
The finding, published in Communications Earth & Environment, offers a cautionary note on how palaeontologists build a picture from the remains of the creatures they study.
CRISPR-based technologies offer enormous potential to benefit human health and safety, from disease eradication to fortified food supplies. As one example, CRISPR-based gene drives, which are engineered to spread specific traits through targeted populations, are being developed to stop the transmission of devastating diseases such as malaria and dengue fever.
Twice a day, at dusk and just before dawn, a faint layer of sodium and other metals begins sinking down through the atmosphere, about 90 miles high above the city of Boulder, Colorado. The movement was captured by one of the world's most sensitive "lidar" instruments and reported today in the AGU journal Geophysical Research Letters.
A new study led by researchers at Washington State University has identified a protein that could be the key to improving treatment outcomes after a heart attack.
Published in the Journal of Biological Chemistry, the research suggests that protein kinase A (PKA) plays a role in heart muscle cell necrosis, a major type of cell death that commonly occurs after reperfusion therapy, the treatment used to unblock arteries and restore blood flow after a heart attack.
Doctors have hoped that antibiotics could benefit patients with chronic lung diseases, but a new study has found no benefit for patients with life-threatening idiopathic pulmonary fibrosis in preventing hospitalization or death.
(Carlisle, Pa.) -- A new study published in the American Journal of Lifestyle Medicine finds critical links between job loss and physical inactivity in young adults during the U.S. Great Recession of 2008-09 that can be crucial to understanding the role of adverse economic shocks on physical activity during the COVID-19 pandemic. It is the first study to examine how job losses during the Great Recession affected the physical activity of young adults in the United States.
Professor Tetsuo Endoh's Group at Tohoku University's Center for Innovative Integrated Electronics has announced a new magnetic tunnel junction (MTJ) quad-technology that provides better endurance and reliable data retention - over 10 years - beyond the 1X nm generation.
