Entomologists at UC Riverside have documented that a species of native sweat bee widespread throughout North and South America has a daily routine that makes it a promising pollinator.
Because the bee can thrive in environments that have been highly modified by humans, such as cities and agricultural areas, it could become a suitable supplement to honeybees, which are expensive for farmers to rent and threatened by pesticides and climate change.
ITHACA, N.Y. - Cells depend on signaling to regulate most life processes, including cell growth and differentiation, immune response and reactions to various stresses.
A lithium-ion battery that is safe, has high power and can last for 1 million miles has been developed by a team in Penn State's Battery and Energy Storage Technology (BEST) Center.
In a recent study, scientists at Baycrest's Rotman Research Institute (RRI) found that research participants moved their eyes to determine whether they had seen an image before, and that their eye movement patterns could predict mistakes in memory. They obtained these results using an innovative new eye tracking technique they developed.
A new study links being overweight in middle age and later adulthood to a greater risk of advanced prostate cancer. Jeanine Genkinger, PhD, an epidemiologist at Columbia University Mailman School of Public Health, and colleagues published the study in Annals of Oncology, the journal of the European Society for Medical Oncology and Japanese Society of Medical Oncology.
Prostate cancer is the second most common cause of cancer in men in the United States. Fewer than one in three men with advanced prostate cancer live five years beyond diagnosis.
EAST LANSING, Mich. - Nearly 30% of the $3.6 trillion spent on health care costs in the United States is wasted. New research from Michigan State University and Rutgers University reveals the amount of money washed away in hospital operating rooms, offering solutions to save hospitals - and the country - millions of dollars each year.
ITHACA, N.Y. - "Scooter clutter" has been a concern amplified by media reports in urban areas where micromobility has entered the landscape, with large numbers of dockless scooters and shared e-bikes on city streets and sidewalks. But a recent study finds that motor vehicles are still the main offender by far when it comes to blocking access by other travelers.
Research co-authored by Nicholas Klein, assistant professor of city and regional planning at Cornell University, offers data on the impacts of scooters and bikeshare vehicles in five American cities.
LAWRENCE -- Some children in the U.S. grow up under severe disadvantage in terms of the amount and quality of language they are exposed to in their earliest years. Researchers have documented that some children are exposed to roughly 30 million fewer words than other children during years that are critical for learning language. Researchers call this the "word gap" and say it portends lifelong consequences.
COLUMBIA, Mo. - Self-inflicted injury, aggression toward others and yelling are common problem behaviors associated with young children diagnosed with autism spectrum disorder. These actions can result from the child being denied attention or access to items they enjoy, as well as from internal discomfort or environmental stressors such as noise or large crowds.
Corals are constantly exposed to multiple environmental stressors at any given time. On a global scale, climate change is increasing seawater temperatures which can cause coral to bleach. Locally, land-use practices can cause poor water quality run-off of land-based fertilizers and sediment washing over our coral reefs.
A "decoy" mechanism has been found in human and animal cells to protect them from potentially dangerous toxins released by foreign invaders, such as bacteria.
DURHAM, N.C. -- An international team of researchers that pooled genetic samples from developmentally disabled patients from around the world has identified dozens of new mutations in a single gene that appears to be critical for brain development.
"This is important because there are a handful of genes that are recognized as 'hot spots' for mutations causing neurodevelopmental disorders," said lead author Debra Silver, an associate professor of molecular genetics and microbiology in the Duke School of Medicine. "This gene, DDX3X, is going to be added to that list now."
What The Study Did: Researchers examined associations between two of the most common weight-loss surgeries on type 2 diabetes outcomes by comparing diabetes remission and relapse rates, glycemic control and weight loss after five years among 9,700 adults with type 2 diabetes who had Roux-en-Y gastric bypass or sleeve gastrectomy.
Authors: Kathleen McTigue, M.D., of the University of Pittsburgh, is the corresponding author.
The conclusions of a study carried out by Víctor Costumero, as the first author, Marco Calabria and Albert Costa (died in 2018), members of the Speech Production and Bilingualism (SPB) group at the Cognition and Brain Center (CBC) of the Department of Information Technology and the Communications (DTIC) of the UPF, together with researchers from the Universities of Jaume I, Valencia, Barcelona and Jaén; IDIBELL, Hospital La Fe (Valencia) and Grupo Médico ERESA (Valencia) show that bilingualism acts as a cognitive reserve factor against dementia.
Exciton-based solid-state devices have the potential to be essential building blocks for modern information technology to slow down the end of Moore's law. Exploiting excitonic devices requires the ability to control the excitonic properties (e.g., exciton flow, exciton recombination rates or exciton energy) in an active medium. However, until now, the demonstrated techniques for excitonic control have either been inherently complex or sacrificed the operation speed, which is self-defeating and impractical for actual implementation.
