Black and Latino neighborhoods in the 30 most populous U.S. cities had fewer pharmacies than white or diverse neighborhoods in 2007-2015, USC research shows, suggesting that 'pharmacy deserts'- like so-called food deserts-may be an overlooked contributor to persistent racial and ethnic health disparities.

Ensuring that veterans have stable housing not only reduces homelessness but also slashes the cost of providing them with publicly funded health care, according to a national study led by University of Utah Health scientists.

An international team of scientists using a Sandia National Laboratories supercomputer in the largest reconstruction ever attempted of prehistoric travel has mapped the probable "superhighways" that led to the first peopling of Australia.

A new study found overlooked tsunami hazards related to undersea, near-shore strike-slip faults, especially for coastal cities adjacent to faults that traverse inland bays. Several areas around the world may fall into this category, including the San Francisco Bay area, Izmit Bay in Turkey and the Gulf of Al-Aqaba in Egypt.

To better understand respiratory diseases and develop new drugs faster, investigators designed a 3D "lung-on-a-chip" model of the distal lung and alveolar structures, the tiny air sacs that take in oxygen as you breathe.

Researchers from NYU Abu Dhabi's Center for Genomics and Systems Biology have successfully sequenced the genome of previously extinct date palm varieties that lived more than 2,000 years ago.

EPFL scientists are beginning to understand why corals in the Gulf of Aqaba, along with their symbiotic algae and bacteria, resist higher temperatures particularly well.

Mullerian inhibiting substance, a reproductive hormone, keeps follicles dormant in the ovaries until they are ready to be activated, grow, and release eggs during ovulation. Understanding the mechanism of follicle development by this hormone could allow scientists, for the first time, to identify novel therapeutic targets to preserve follicles and eggs lost to aging or chemotherapy, to improve the harvesting of eggs during IVF, and to create a new hormonal contraceptive.

An influenza vaccine that is made of nanoparticles and administered through the nose enhances the body's immune response to influenza virus infection and offers broad protection against different viral strains, according to researchers in the Institute for Biomedical Sciences at Georgia State University.

Researchers analyzed data on more than 20,000 patients admitted to hospitals for COVID-19. After controlling for patient age, sex, comorbidities, and severity of disease when the patient was admitted, they found that none of these factors fully explained the decline in mortality rates.

Silicon-based fiber optics are currently the best structures for high-speed, long distance transmissions, but graphene -- an all-carbon, ultra-thin and adaptable material -- could improve performance even more.

New work from a Stanford University-led team of researchers including Carnegie's Arthur Grossman and Tingting Xiang unravels a longstanding mystery about the relationship between form and function in the genetic material of a diverse group of algae called dinoflagellates. Their findings, published in Nature Genetics, have implications for understanding genomic organizational principles of all organisms.

ORNL story tips: Stealthy air leak detection, carbon to chemicals and recycling goes large.

People have become accustomed to having their temperature checked during the pandemic because fever is a key indicator of COVID-19. A new commentary written by faculty in Washington State University's College of Nursing proposes that taking a temperature is a less useful indicator of infection in older adults and that a pulse oximeter be used instead. It said a fever may be overlooked because older adults' baseline temperatures are lower.

A new Cornell University-led study examines how temperature affects fishing behavior and catches among inland fisher households in Cambodia, with important implications for understanding climate change.

A team of scientists has discovered the fossil of an organism with two distinct cell types that is likely the oldest of its kind ever recorded -- revealing multicellularity perhaps 400 million years before it first appeared in animals, they report in the journal Current Biology. The discovery in the Scottish Highlands suggests that cell differentiation and segregation occurred at least one billion years ago and may have occurred in freshwater lakes rather than the ocean.

Patients with one or more health conditions are more likely to be screened for colorectal cancer than those without comorbidities, according to new research in the Journal of Osteopathic Medicine. However, patients with five or more health conditions are also less likely to be screened than patients with two to four health conditions.

"We confirmed the longitudinal stability of social cognition deficits in cognitively-normal people with relapsing-remitting MS, mirroring the amygdala structural damage and psychological well-being," said Dr. Genova. "These results confirm that social cognition exerts a key role in MS, affecting individuals' everyday lives. Our research highlights the need to identify treatments to improve social cognition in this population."

The Bornean subspecies of Rajah scops owl (Otus brookii brookii), documented in the wild for the first time since 1892, may be its own unique species and deserving of a conservation designation. Published April 28 in The Wilson Journal of Ornithology, Smithsonian Migratory Bird Center ecologist Andy Boyce reported the rediscovery and photographed this elusive subspecies in the mountainous forests of Mount Kinabalu in Sabah, Malaysia.

Exposure to air pollution, even over the course of just a few weeks, can impede mental performance, according to a new study led by researchers at Columbia University Mailman School of Public Health. However, these adverse effects were lessened in people taking nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin. The study is among the first to explore short-term air pollution exposures and the use of NSAIDs to mitigate their effects. The results are published in the journal Nature Aging.
