WASHINGTON, Aug. 17, 2020 -- At 11 million cases annually, urinary tract infections (UTIs) are the most common outpatient infections in the U.S., according to the U.S. Department of Health and Human Services. At least half of all women will have a UTI during their lifetimes, and many of the infections -- which have increasingly become resistant to a wide array of antibiotics -- recur. Now, researchers report early progress toward developing a new class of antibiotics that would fight these infections by starving the causative bacteria of iron.
ANN ARBOR, Mich. -- Cookies for breakfast, staying up late and maybe a little more TV than usual.
For some families, what happens at grandma's house stays at grandma's house.
But for others, clashes over parenting choices and enforcing parents' rules can cause major strife between a child's parents and grandparents, a national poll suggests.
Lenses are one of the most commonly used optical components in daily life, including eyeglasses, microscopic objectives, magnifying glass, and camera lenses. Conventional lenses are based on the principle of light refraction, using different materials, spherical surfaces and spatial positions to achieve the control of light. The fabrication of conventional lenses including the processes of material selection, cutting, rough grinding, fine grinding, polishing, and testing.
Native to India, teak is the go-to species for reforestation in Central America. But teak often underperforms in the nutrient poor soils that dominate tropical landscapes. To discover if the timber value of teak plantations grown on poor soils can be increased, scientists at the Smithsonian Tropical Research Institute interplanted rosewood and amarillo, both economically valuable native tree species.
Anschutz researchers overturn hypothesis underlying the sensitivity of the mammalian auditory system
AURORA, Colo. (August 14, 2020) - A new study from the University of Colorado Anschutz Medical Campus challenges a decades-old hypothesis on adaptation, a key feature in how sensory cells of the inner ear (hair cells) detect sound.
A world-first study examining the scales of management of the Great Barrier Reef has the potential to help sustain other ecosystems across the world.
Massive marine ecosystems like the Great Barrier Reef aren't just a vibrant home to fish, corals and other creatures, they are also an important source of people's food, livelihoods and recreation.
Ammonia is a generic precursor for the manufacture of essential fertilizer and most nitrogen-containing organic chemicals. To date, industrial ammonia production is predominantly conducted by the Haber-Bosch process, in which nitrogen is fixed using the chemical reductant hydrogen. However, despite the development for more than one hundred years, this process still requires harsh conditions including high temperatures (673-873 K) and pressures (20-40 MPa), accounting for 1.5% of worldwide energy consumption.
A new study led by the Department of Biosciences at Durham University, UK, is the first large-scale assessment of how recent changes in both climate and land cover have impacted populations of migrating birds.
The co-authors, Associate Professor Dinar Fazullin and Associate Professor Gennady Mavrin, have been engaged in the topic of membrane elements for water purification for ten years. This research area is very pertinent because of the large volumes of liquid waste and a lack of specialized types of membranes.
URBANA, Ill. - Bird biodiversity is rapidly declining in the U.S. The overall bird population decreased by 29% since 1970, while grassland birds declined by an alarming 53%.
Valuable for so much more than flight and song, birds hold a key place in ecosystems worldwide. When bird numbers and varieties dwindle, pest populations increase and much-needed pollination decreases. Those examples alone negatively impact food production and human health.
Past discriminatory housing practices may play a role in perpetuating the significant disparities in infant and maternal health faced by people of color in the U.S., suggests a new study by researchers at the University of California, Berkeley.
PHOENIX, Ariz. -- Aug. 14, 2020 -- A review article authored by a researcher at the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggests that following menopause, women are at higher risk for developing nonalcoholic fatty liver disease (NAFLD), a chronic condition caused by the build-up of excess fat in the liver not caused by alcohol.
If you could dive down to the ocean floor nearly 540 million years ago just past the point where waves begin to break, you would find an explosion of life--scores of worm-like animals and other sea creatures tunneling complex holes and structures in the mud and sand--where before the environment had been mostly barren.
Dr. Abhishek Jain, assistant professor in the Department of Biomedical Engineering and the Department of Medical Physiology in the College of Medicine, collaborated with researchers from the Departments of Gynecologic Oncology and Cancer Biology at MD Anderson Cancer Center to gain a better understanding of the interaction among ovarian cancer tumors, blood vessels and platelets. They found that tumors break the blood vessel barriers so that they can communicate with the blood cells, such as platelets.
COLUMBUS, Ohio - A new federal rule that determines how the Clean Water Act is implemented leaves millions of miles of streams and acres of wetlands unprotected based on selective interpretation of case law and a distortion of scientific evidence, researchers say in a new publication.
