Brain
University of Maryland School of Medicine (UMSOM) researchers have shown that psilocybin--the active chemical in "magic mushrooms"-- still works its antidepressant-like actions, at least in mice, even when the psychedelic experience is blocked. The new findings suggest that psychedelic drugs work in multiple ways in the brain and it may be possible to deliver the fast-acting antidepressant therapeutic benefit without requiring daylong guided therapy sessions.
Study: "Untested Admissions: Examining Changes in Application Behaviors and Student Demographics Under Test-Optional Policies"
Author: Christopher Bennett (Vanderbilt University)
This study was published today in American Educational Research Journal.
Key Findings:
PRINCETON, N.J.--Increasing diversity remains a key priority at universities, especially in the wake of mass demonstrations in support of racial equality in 2020 following the death of George Floyd. Many universities are guided by the motivation that diversity enhances student learning, a rationale supported by the U.S. Supreme Court.
Researchers have used a technique similar to MRI to follow the movement of individual atoms in real time as they cluster together to form two-dimensional materials, which are a single atomic layer thick.
The results, reported in the journal Physical Review Letters, could be used to design new types of materials and quantum technology devices. The researchers, from the University of Cambridge, captured the movement of the atoms at speeds that are eight orders of magnitude too fast for conventional microscopes.
Blood taken from a small group of children before the COVID-19 pandemic contains memory B cells that bind SARS-CoV-2 and weakly cross-react with other coronaviruses, a new study finds, while adult blood and tissue showed few such cells. "Further study of the role of cross-reactive memory B cell populations... will be important for ongoing improvement of vaccines to SARS-CoV-2, its viral variants, and other pathogens," the authors say.
CPR training offered to just over half of surveyed ON high school students despite mandated training
Just over half of surveyed Ontario high schools reported providing CPR and AED training to students despite being mandated by the province to provide training for the lifesaving technique, according to a new study by Unity Health Toronto researchers.
A new biosealant therapy may help to stabilize injuries that cause cartilage to break down, paving the way for a future fix or - even better - begin working right away with new cells to enhance healing, according to a new animal-based study by researchers at the Perelman School of Medicine at the University of Pennsylvania. Their research was published in Advanced Healthcare Materials.
During the acute phase of the COVID-19 pandemic, emergency department doctors, nurses and other frontline staff experienced unprecedented levels of stress and emotional exhaustion that included nightmares or insomnia, according to a UC San Francisco-led study of emergency departments across the country.
The study, among the first to assess mental health effects of the pandemic at a geographically diverse sample of emergency rooms, found that nearly one-fifth of the ER staff were at elevated risk for post-traumatic stress disorder (PTSD).
An international team working at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) used a unique X-ray instrument to learn new things about lithium-rich battery materials that have been the subject of much study for their potential to extend the range of electric vehicles and the operation of electronic devices.
The concentration of the radioactive element radon is known to change in the ground before and after earthquakes. Previous studies have shown elevated radon levels in the atmosphere before the mainshock of a large inland earthquake due to foreshock activity and slow slip.
But now, researchers from Tohoku University have revealed an anomaly in this phenomenon. Through the analysis of data before and after the 2018 Northern Osaka Earthquake, they discovered that the atmospheric radon concentration decreased.
What The Study Did: This survey study uses self-reported data from a national study of veterans to assess the association of symptoms of posttraumatic stress disorder with posttraumatic psychological growth (these are positive psychological changes such as an appreciation of life and personal growth) among U.S. veterans during the COVID-19 pandemic.
Authors: Robert H. Pietrzak, Ph.D., M.P.H., of the U.S. Department of Veterans Affairs National Center for Posttraumatic Stress Disorder and the VA Connecticut Healthcare System in West Haven, is the corresponding author.
Calibration and validation (CAL/VAL) is a key technology for quantitative application of space-borne remote sensing data. However, the complex space environment can cause many uncertainties and degrade the calibration accuracy. In-flight calibration is always needed. The thermal emission of the Moon is stable over hundreds of years because there is no atmosphere and no significant physical or chemical change on its surface. The deep space view of the Microwave Humidity Sounder onboard NOAA-18 has viewed the Moon many times every year.
The rainfall over the Yangtze River Valley (YRV) in June 2020 broke the record since 1979 (Figure 1). As of June 28, the People's Daily Online reported that there were more than 12 million people affected by flood disasters related to this torrential rain, with deaths or disappearances of 78 persons and a direct economic loss of more than 25 billion CNY. Recently, scientists from South China Sea Institute of Oceanology (SCSIO), Chinese Academy of Sciences revealed the cause of the record-breaking rainfall over the YRV.
Data collected from 337 cities across 18 countries show that even slight increases in ambient carbon monoxide levels from automobiles and other sources are associated with increased mortality.
Boulder, Colo., USA: Gale Crater's central sedimentary mound (Aeolis Mons or, informally, Mount Sharp) is a 5.5-km-tall remnant of the infilling and erosion of this ancient impact crater. Given its thickness and age, Mount Sharp preserves one of the best records of early Martian climatic, hydrological, and sedimentary history.
In this paper, published today in Geology, William Rapin and colleagues present the first description of key facies in the sulfate-bearing unit, recently observed in the distance by the rover, and propose a model for changes in depositional environments.
