Sept. 22, 2020-- A new Viewpoint piece published online in the Annals of the American Thoracic Society examines the ways in which COVID-19 disproportionately impacts historically disadvantaged communities of color in the United States, and how baseline inequalities in our health system are amplified by the pandemic. The authors also discuss potential solutions.
New light is being shed on a little-known role of Y chromosome genes, specific to males, that could explain why men suffer differently than women from various diseases, including Covid-19.
The findings were published this month in Scientific Reports by Université de Montréal professor Christian Deschepper, director of the Experimental Cardiovascular Biology research unit of the Montreal Clinical Research Institute.
In one of the first studies to comprehensively analyze Y chromosomes of humans' two closest relatives, Denisovans and Neanderthals, researchers report what prior studies have suggested: early gene flow events between archaic and modern humans led to the eventual replacement of archaic Neanderthal Y chromosomes by introgressed Homo sapiens Y chromosomes. There was no replacement of Denisovan Y chromosomes with H. sapiens Y chromosomes. "Until [this] new study ...
What The Study Did: Researchers investigated the effectiveness of using measurements of how pupils react to light as physiologic biomarker to help diagnose sports-related concussion in adolescents.
Authors: Christina L. Master, M.D., of Children's Hospital of Philadelphia, is the corresponding author.

AURORA, Colo. (Sept. 24, 2020) - Some forms of blindness and visual impairment can be cured with a corneal transplant surgery using donated eye tissue. However, federal regulations in the United States and Canada severely restrict the ability of sexually active gay and bisexual men from donating their eye tissue.
During the initial phase of COVID-19 lockdown, rates of loneliness among people in the UK were high and were associated with a number of social and health factors, according to a new study published this week in the open-access journal PLOS ONE by Jenny Groarke of Queen's University Belfast, UK, and colleagues.
The explosive growth of internet use leads to an explosion of the energy consumption of data centers. Vertical cavity surface emitting lasers VCSELs are key enabling devices meeting the requirements of optical interconnects in such data centers up to a few hundred meters of single or multimode fiber due to their simplicity, low cost, and large data transmission rates. Achieving larger bit rates has been the stated goal of research and development during the last years.
Tsukuba, Japan - Tiny organisms head out on the highway, looking for adventure like they've ridden straight out of the 1960s rock hit, "Born to Be Wild." Researchers from Japan have discovered that while perhaps not as thrill-seeking, bacteria do indeed travel on fungal highways and pay a toll in return.
In a study published this month in Life Science Alliance, researchers from the University of Tsukuba have revealed a mutual bacterial-fungal relationship that lets bacteria travel in exchange for thiamine.
High levels of air pollution are forcing people inside to consume more electricity, subsequently causing even greater environmental problems by increasing greenhouse gas emissions.
This is according to a new study from researchers at Cardiff University who have shown that the effects are seen more in lower-income families and those from ethnic minority backgrounds.
The team say the results should encourage decision makers to think about how policy can prevent inequality from widening in terms of both health risks and financial hardships.
CAMBRIDGE, MA - September 24, 2020--This week, the American Academy of Arts and Sciences and the MIT Press published a new issue of Daedalus that features essays by sixteen prominent climate change witnesses, representing multiple fields, backgrounds, and generations. Guest edited by Nancy L.
Researchers from HSE University compared the effect of two meditation practices - loving-kindness meditation (LKM) and compassion meditation (CM). Loving-kindness meditation turned out to be more effective when it comes to increasing happiness, but, in contrast with previous studies, compassion meditation also did not result in a growth of negative emotions. The paper was published in Mindfulness journal.
The team reported on their findings and conclusions in the British Journal of Sports Medicine on 26 August 2020.
Apps such as Uber are an important mobility feature in many big cities. Driving others from A to B in their own car has become a job for many people. However, many drivers complain that their income is too low. In May 2019, the US television station ABC reported how Uber drivers at Washington airport artificially inflated the price of the service by all going offline at the same time. Within a few minutes, the price of the service had risen by 13 dollars, which almost doubled the amount.
New dedicated hubs for Deaf children are needed around the country to provide new social spaces, education and support, an expert has said.
Special schools for Deaf children have had an important role in the Deaf community, acting as places people can meet and learn BSL together. But the move to inclusive education and new technology such as cochlear implants means most children with hearing loss are now educated in mainstream schools.
New research published in EPJ B reveals that the higher-than-expected efficiency of PLEDs can be reached through interactions between triplet excitons, and impurities embedded in their polymer layers.
Molecular dynamics simulations have shown that the mysteriously high efficiency of polymer LEDs arises from interactions between triplet excitons in their polymer chains, and unpaired electrons in their molecular impurities.
