Using naturalistic driving data and machine learning techniques, researchers have developed highly accurate algorithms for detecting mild cognitive impairment and dementia in older drivers. Naturalistic driving data refer to data captured through in-vehicle recording devices or other technologies in the real-world setting. These data could be processed to measure driving exposure, space and performance in great detail.

Uncapped, idle oil wells could be leaking millions of kilograms of methane each year into the atmosphere and surface water, according to a study by the University of Cincinnati.

The highly infectious SARS-CoV-2 variant that recently emerged in South Africa, known as B.1.351, has scientists wondering how existing COVID-19 vaccines and therapies can be improved to ensure strong protection. Now, researchers reporting in ACS' Journal of Medicinal Chemistry used computer modeling to reveal that one of the three mutations that make variant B.1.351 different from the original SARS-CoV-2 reduces the virus' binding to human cells -- but potentially allows it to escape some antibodies.

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been linked to eye troubles and sleep disturbances. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a prototype LED that reduces -- instead of masks -- the blue component, while also making colors appear just as they do in natural sunlight.

Difficult-to-treat, chronic wounds in preclinical models healed with normal scar-free skin after treatment with an acellular product discovered at Mayo Clinic. Derived from platelets, the purified exosomal product, known as PEP, was used to deliver healing messages into cells of preclinical animal models of ischemic wounds. The Mayo Clinic research team documented restoration of skin integrity, hair follicles, sweat glands, skin oils and normal hydration.

Scientists have launched an ambitious effort to produce high-quality reference genomes for all vertebrate species, from mammals to birds and reptiles. The result could be discoveries with implications for animal conservation as well as human health and disease.

Business schools need to revise their faculty research incentives to ensure their faculty produce research that lives up to society's expectations and improves managers and firms' decision making.

Scientists call it oxytocin in humans, isotocin in fish, mesotocin in birds, and valitocin in sharks. But according to a new study, it's all the same hormone--and high time we settled on just one name.

Researchers found that difficulties in diagnosing toddlers with autism spectrum disorder (ASD) might be due to the dynamic nature of the disorder during child development. Children with clinical characteristics that put them on the diagnostic border of autism have an increased susceptibility to gaining or losing that diagnosis at later ages.

Injectable dermal fillers provide a minimally invasive approach to reduce facial lines and wrinkles while restoring volume and fullness in the face. More than 2.7 million dermal filler procedures were performed in 2019, according to the most recent statistics from the American Society of Plastic Surgeons (ASPS).

Research News Tip Sheet: Story Ideas From Johns Hopkins Medicine

A Ludwig Cancer Research study has identified a previously unrecognized mechanism by which cancer cells of a relatively benign subtype of pancreatic tumors methodically revert--or "de-differentiate"--to a progenitor, or immature, state of cellular development to spawn highly aggressive tumors that are capable of metastasis to the liver and lymph nodes.

Scientists mapped the electronic states in an exotic superconductor. The maps point to the composition range necessary for topological superconductivity, a state that could enable more robust quantum computing.

Children and young adults with compromised immune systems may harbor the SARS-CoV-2 virus for extended periods of time, allowing the virus to mutate.

The new discovery points to potential ways to prevent Sudden Unexpected Death in Epilepsy.

Analysis of data from a lightning mapper and a small, hand-held radiation detector has unexpectedly shed light on what a gamma-ray burst from lightning might look like - by observing neutrons generated from soil by very large cosmic-ray showers.

Seasonally occurring fields of aufeis (icing) constitute an important resource for the water supply of the local population in the Upper Indus Basin. Geographers of Heidelberg University have now examined the spreading of aufeis and, for the first time, created a full inventory of these more than 3,700 aufeis fields. They are important for these high mountain areas between South and Central Asia, particularly with respect to hydrology and climatology.

University of Minnesota Medical School researchers say "tumor-secreted exosomes" help some cancer cells to evade immune response of current FDA-approved treatment options.

New research from the University of Kansas just published in the International Journal of Behavioral Medicine is shedding light on the biopsychosocial process that can lead to poor grades, withdrawal from classes and even students who drop out.

Matching the capability of different tree species with the types of contaminants present in soil and water is critical in phytoremediation. A USDA Forest Service and University of Missouri research team has developed a new contaminant prioritization tool that has the potential to increase the effectiveness of phytoremediation in landfill clean-up.
