US counties with more social capital have fewer COVID-19 infections and deaths

New research from Simon Fraser University shows that women's voices continue to be underrepresented in the media, despite having prominent female leaders across Canada and internationally. Researchers in SFU's Discourse Processing Lab found that men outnumber women quoted in Canadian news media about three to one. The findings from the team's Gender Gap Tracker study were published this week in the journal PLOS ONE. The research team collected data from seven major Canadian media outlets from October 2018 to September 2020. Over the two-year period, 29 per cent of people ...

The development of scanning probe microscopes in the early 1980s brought a breakthrough in imaging, throwing open a window into the world at the nanoscale. The key idea is to scan an extremely sharp tip over a substrate and to record at each location the strength of the interaction between tip and surface. In scanning force microscopy, this interaction is -- as the name implies -- the force between tip and structures on the surface. This force is typically determined by measuring how the dynamics of a vibrating tip changes as it scans over objects deposited on a substrate. A common analogy is tapping a finger across a table and sensing objects placed ...

A new study by Indiana University found women, younger individuals, those with lower levels of formal education, and people of color are being hit hardest by the COVID-19 pandemic. The study, published in the Proceedings of the National Academy of Sciences journal, found that Black adults were three times as likely as whites to report food insecurity, being laid off, or being unemployed during the pandemic. Additionally, residents without a college degree were twice as likely to report food insecurity (compared to those with some college) while those not completing high school are four times as likely to report it, compared ...

Cases of symptomatic COVID-19 were extremely low among children and staff at a network of YMCA summer camps held last year in North Carolina that took precautions like masking and physical distancing, with close to zero transmissions occurring at the camps, according to researchers at Duke Health, Weill Cornell Medicine and NewYork-Presbyterian. In the camps' 2020 sessions, there were 19 cases of COVID-19 among 5,344 staff and 1,486 youth, only two of which were linked to possible on-site transmission at a group of YMCA of the Triangle camps, at a time ...

The modern world is powered by electrical circuitry on a "chip"--the semiconductor chip underpinning computers, cell phones, the internet, and other applications. In the year 2025, humans are expected to be creating 175 zettabytes (175trillion gigabytes) of new data. How can we ensure the security of sensitive data at such a high volume? And how can we address grand-challenge-like problems, from privacy and security to climate change, leveraging this data, especially given the limited capability of current computers? A promising alternative is emerging quantum communication and computation technologies. For this to happen, however, it will require the widespread ...

Enterocytes, which line the epithelium of the small intestine, are the sites of absorption and metabolism of most orally consumed medications. For this reason, studies on the absorption of novel oral drugs rely on in vitro or animal models to accurately recreate the environment of the small intestine. Currently, scientists widely use the human colon cancer cell line Caco-2 as a model of the intestinal epithelium. However, this has its drawbacks: Caco-2 cells have been derived from the colon; therefore, they more closely resemble the colon than the small intestine. For example, these cells do not express cytochrome P450 3A4 (CYP3A4), a protein critical for drug metabolism that is abundantly expressed in the small intestine. Moreover, Caco-2 ...

Fresno, CA - A recent human study published in the Journal of the American Academy of Dermatology found that consuming grapes protected against ultraviolet (UV) skin damage.1 Study subjects showed increased resistance to sunburn and a reduction in markers of UV damage at the cellular level. 2 Natural components found in grapes known as polyphenols are thought to be responsible for these beneficial effects. The study, conducted at the University of Alabama, Birmingham and led by principal investigator Craig Elmets, M.D., investigated the impact of consuming whole grape powder - equivalent to 2.25 cups of grapes ...

DALLAS - Feb. 5, 2021 - The COVID-19 pandemic is having a detrimental impact on substance use, mental health, and weight-related health behaviors among people with obesity, according to a new study by researchers at UT Southwestern and the END ...

Health care and education systems are two main pillars of a community's stability. How well and how quickly a community recovers following a natural disaster depends on the resilience of these essential social services. New research from the Colorado State University Department of Civil and Environmental Engineering, published in Nature Scientific Reports, has found hospitals and schools are interdependent, suggesting their collective recovery must be considered in order to restore a community in the wake of disaster. Because hospitals and schools are so integral to a community's well-being, Associate Professor Hussam Mahmoud and Ph.D. graduate student Emad Hassan wanted to determine the correlation between them to understand their overall influence on community ...

UCLA materials scientists and colleagues have discovered that perovskites, a class of promising materials that could be used for low-cost, high-performance solar cells and LEDs, have a previously unutilized molecular component that can further tune the electronic property of perovskites. Named after Russian mineralogist Lev Perovski, perovskite materials have a crystal-lattice structure of inorganic molecules like that of ceramics, along with organic molecules that are interlaced throughout. Up to now, these organic molecules appeared to only serve a structural function and could not directly contribute to perovskites' electronic performance. Led by UCLA, a new study shows that when the organic molecules ...
