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.
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.
Researchers can now identify T cells reactive to a particular target from a patient's cells, and to perform high-throughput single-cell RNA sequencing of those cells.
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.
For those using illicit opioids to manage their chronic pain, cannabis may be a beneficial -- and a less dangerous -- alternative, according to new research.
Neurons that produce the neurotransmitter dopamine communicate with T cells to enhance allergic inflammation in the lungs of young mice but not older mice, researchers report. The findings potentially explain why asthma susceptibility is higher in children. By highlighting the important role of interactions between the nervous system and the immune system in childhood asthma, the results could lead to new strategies for treating the common chronic disease.
Ochre was often used as a vivid red paint in ancient rock art known as pictographs. Despite its broad use throughout human history and a modern focus on how the artistic symbolism is interpreted, little research exists on the paint itself and how it was produced. Now, scientists are using electron microscopes to understand how ochre paint was created by hunter-gatherers in North America to produce rock art located at Babine Lake in British Columbia.
Vehicles moving at hypersonic speeds are bombarded with ice crystals and dust particles in the surrounding atmosphere, making the surface material vulnerable to damage such as erosion and sputtering with each tiny collision. Researchers studied this interaction one molecule at a time to understand the processes, then scaled up the data to make it compatible with simulations that require a larger scale.
Researchers investigate and describe the conservation importance of buildings relative to natural, alternative roosts for little brown bats in Yellowstone National Park.
New research has found that boredom is rising year after year for teens in 8th, 10th, and 12th grades, with greater increases for girls than boys.
Yoga and physical therapy (PT) are effective approaches to treating co-occurring sleep disturbance and back pain while reducing the need for medication, according to a new study. The research showed significant improvements in sleep quality lasting 52 weeks after 12 weeks of yoga classes or 1-on-1 PT, which suggests a long-term benefit of these non-pharmacologic approaches.
Ever see a bee stuck in a pool? He's surfing to escape.
Husbands are least stressed when their wives earn up to 40% of household income but they become increasingly uncomfortable as their spouse's wages rise beyond that point.
The leftovers from a spectacular supernova that revolutionized our understanding of how stars end their lives have finally been spotted by astronomers.
Down syndrome, due to an extra chromosome 21, occurs in 250,000 children and adults in the United States, making it the country's most common chromosomal disorder. Inherited heart defects, thyroid cancer, celiac disease and developmental disabilities are common Down syndrome complications. Only recently has catatonia, a behavioral condition marked by new onset immobility, mutism, withdrawal and other behavioral abnormalities, been recognized in Down syndrome.
Genetic analyses have revealed remarkably higher species diversity in common red seaweed than previously assumed. It was thought that there were only five related species of the Gloiopeltis genus worldwide. However, it has been revealed that there are over ten in Japan alone.
Researchers have, for the first time, successfully demonstrated a formation and current-induced motion of synthetic antiferromagnetic magnetic skyrmions. The established findings are expected to pave the way towards new functional information processing and storage technologies.
Scientists have found a new way to make ultra-clean carbon nanotube transistors with superior semiconducting properties.
The discovery of gases released from deep beneath the Earth's crust could help to explain Southern Africa's unusual landscape, a study suggests.
By understanding how, when, and why badgers move from one social group to another, researchers hope information gleaned from GPS devices will help them tailor vaccination programs to reduce the spread of bovine tuberculosis.
