A recent survey of the approximately 274,000 City University of New York (CUNY) students published in the Journal of Urban Health found that the Covid-19 pandemic has taken a toll on their mental health and financial security.
Using data collected in a NASA Langley Mach 6 wind tunnel, researchers at the University of Illinois Urbana-Champaign replicated the hypersonic flow conditions of a compression ramp flow by means of Direct Numerical Simulation. The simulation yielded an abundance of additional data, which can be used to better understand the phenomena that occur surrounding vehicles traveling at hypersonic speeds.
Parents who reported more hassles using a child car seat or booster seat - such as the child is uncomfortable or having to make multiple trips in a day - were less likely to follow recommendations from the American Academy of Pediatrics (AAP) on child passenger safety, according to a study published in the journal Academic Pediatrics.
Wine lovers recognize that a perfectly paired wine can make a delicious meal taste even better, but the reverse is also true: Certain foods can influence the flavors of wines. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have explored how lipids -- fatty molecules abundant in cheese, meats, vegetable oils and other foods -- interact with grape tannins, masking the undesirable flavors of the wine compounds.
DALLAS, March 3, 2021 -- American Indian people with atrial fibrillation (AFib) had the highest risk of non-hemorrhagic stroke when compared with people in other racial and ethnic groups, and they also experienced the highest overall risk for stroke even without atrial fibrillation (AFib), according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.
In a report summary released today Thomas McAndrew, a computational scientist and assistant professor at Lehigh University's College of Health includes probabilistic forecasts of the impact of vaccines and variants on the U.S. COVID trajectory over the next few weeks.
Researchers have captured the first detailed images of newborn babies' lungs as they take their first breaths.
The research, led by the Murdoch Children's Research Institute (MCRI) and published the American Journal of Respiratory and Critical Care Medicine, provides a breakthrough in understanding the events around a baby's first breath, why healthy babies cry at birth and provides clues to improving preterm babies' survival chances and long term health outcomes.

The models used to produce global climate scenarios may overestimate the energy and emission savings from improved energy efficiency, warns new research led by academics at the University of Sussex Business School and the University of Leeds.
In a review of 33 studies, the researchers find that economy wide rebound effects may erode around half of the energy and emission savings from improved energy efficiency.
Professor Christiani Jeyakumar Henry, Senior Advisor of Singapore Institute of Food and Biotechnology Innovation (SIFBI), Agency for Science, Technology and Research (A*STAR) and his team have developed a Glycaemic Index (GI) glossary of non-Western foods. The research paper was published in Nutrition & Diabetes on 6 Jan 2021: https://doi.org/10.1038/s41387-020-00145-w.
Targeted, efficient and with few side effects: A new method for combating periodontitis could render the use of broad-spectrum antibiotics superfluous. It was developed and tested for the first time by a team from Martin Luther University Halle-Wittenberg (MLU), the Fraunhofer Institute for Cell Therapy and Immunology IZI and Periotrap Pharmaceuticals GmbH. The aim is to neutralise only bacteria that cause periodontitis while sparing harmless bacteria. The study appeared in the Journal of Biological Chemistry.
A variant of SARS-CoV-2 that emerged in southeast England in November 2020 is more transmissible than pre-existing variants, a new modeling study finds. Further analyses suggest the variant - VOC 202012/01 - will lead to large resurgences of COVID-19 cases. "Without stringent control measures, including limited closure of educational institutions and a greatly accelerated vaccine roll-out, COVID-19 hospitalizations and deaths across England in 2021 will exceed those in 2020," the study's authors say.
UPTON, NY--Physically confined spaces can make for more efficient chemical reactions, according to recent studies led by scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory. They found that partially covering metal surfaces acting as catalysts, or materials that speed up reactions, with thin films of silica can impact the energies and rates of these reactions. The thin silica forms a two-dimensional (2-D) array of hexagonal-prism-shaped "cages" containing silicon and oxygen atoms.
For nearly a century, improvement in human healthcare has depended heavily on the efficiency with which we can treat bacterial diseases. But today, antibiotic resistance--the ability of certain mutant super-bacteria to block out antibiotics--poses a major threat to healthcare, food security, and overall social development worldwide, threatening to upend much of the progress our civilization has achieved.
Pesticides used in forestry may threaten species in downstream rivers and estuaries, but little is known about the extent to which this occurs. A new study by researchers at Portland State University found mussels, clams and oysters in watersheds along the Oregon Coast are exposed to pesticides used in managing forests. The results of this study, published in the journal Toxics, have implications for developing better forest management practices that are less likely to negatively affect aquatic life.
