A nasal antiviral created by researchers at Columbia University Vagelos College of Physicians and Surgeons blocked transmission of SARS-CoV-2 in ferrets, suggesting the nasal spray also may prevent infection in people exposed to the new coronavirus, including recent variants
The compound in the spray--a lipopeptide developed by Matteo Porotto, PhD, and Anne Moscona, MD, professors in the Department of Pediatrics and directors of the Center for Host-Pathogen Interaction--is designed to prevent the new coronavirus from entering host cells.
Meteorologists frequently study precipitation events using radar imagery generated at both ground level and from satellite data. Radar sends out electromagnetic waves that "bounce" off ice or water droplets suspended in the air. These waves quickly return to the radar site in a process named "backscattering." Scientists have observed that backscattering reaches its peak during the melting process as water falls through the atmosphere. High backscattering typically results in warm color returns on a radar displays, indicating heavy precipitation.
Cryptomeria japonica, or the Japanese cedar, is highly revered as the national tree of Japan. Locally known as "sugi," it covers over 4.5 million hectares of land, accounting for nearly half of Japan's artificial forests. However, it is also notorious for causing hay fever, with a good 26.5% of Japan's population reporting cedar pollen allergies in 2008. Over the past years, pollen allergy caused by this conifer has become a widespread social issue among Japanese residents, with many having to avoid going outdoors during pollen season.
Cardiovascular system can be regarded as a mechanical system centered on the heart. Blood flow in the vascular system, hemodynamics factors within the vasculature contain wall shear stress, circumferential wall tensile stress and hydrostatic pressure. Mechanical forces play an important role in vasculature and circulation, such as rapid regulation of vascular wall elasticity, administration of vascular remodeling, and the formation of arteriosclerotic lesions.
After seven years of intense research, a research group from Aarhus University has succeeded - through an interdisciplinary collaboration - in understanding why a very extended structure is important for an essential protein from the human immune system. The new results offer new opportunities for adjusting the activity of the immune system both up and down. Stimulation is interesting in relation to cancer treatment, while inhibition of the immune system is used in treatment of autoimmune diseases.
In the search for planets capable of sustaining life, an international research team with members from ETH has taken a significant step forward. As the researchers reported recently in the journal Nature Communications, they found signs of a Neptune-sized planet in the Alpha Centauri star system, a mere 4.4 light years away from Earth. This exoplanet is located in a zone that may offer suitable conditions for life. The team was able to collect data with unprecedented sensitivity, thus registering even very weak signals.
Earth is a disruptive factor
Experts say English slang and regional dialect should not be banned from classrooms but when you're getting to grips with a second language how helpful is it to learn non-standard lingo?
Very, says Sascha Stollhans, of the Department of Languages and Cultures at Lancaster University, who argues that standardised language norms are artificial and language learners should learn about all aspects of language, even the controversial ones.
In his policy paper, just published in the Languages, Society & Policy Journal, he says:
Researchers from the University of Granada warn that an accumulation of fatty tissue in the neck (both the double chin and the deeper deposits, located between muscles and around the cervical vertebrae) is a predictor of central and overall adiposity, cardiometabolic risk, and a pro-inflammatory profile in sedentary young adults.
Ground-breaking research led by University of Limerick has revealed for the first time that the immune system directly links personality to long-term risk of death.
The study sheds new light on why people who are more conscientious tend to live longer.
Results from the new international study published in the journal Brain, Behavior, and Immunity have found that the immune system plays a previously unknown role in the link between personality traits and long-term risk of death.
Women who gave birth during the COVID-19 pandemic report having felt greater stress in the delivery process, and rate lower the quality of care received.
Furthermore, almost 15% more women developed symptoms of postpartum depression after giving birth during the pandemic
Studies have shown that SARS-CoV-2 remains active on aerosols and surfaces for between several hours and several days, depending on the nature of the surface and environmental conditions. Presently, researchers from Tel Aviv University have demonstrated that ozone, which has already long been used as an antibacterial and antiviral agent in water treatment, effectively sanitizes surfaces against Coronavirus after short exposure to low concentrations of ozone. The research team was led by Dr.
People with attention-deficit / hyperactivity disorder (ADHD) combined with disruptive behaviour disorders (DBDs) share about the 80% of genetic variants associated with aggressive and antisocial behaviours.
COLUMBUS, Ohio - Though Ohio never formally enacted a so-called "heartbeat bill" banning abortions after six weeks of gestation, legislative and legal actions appear to have fueled beliefs that abortion is illegal in the state, a new study has found.
One in 10 Ohio women surveyed for the study thought abortion was prohibited. The percentage with that belief increased from 5% to 16% during the study period, corresponding to sustained activity to limit abortions from fall of 2018 through summer of 2019. The study appears in the American Journal of Obstetrics and Gynecology.
Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes - roughly 1.65 billion tons annually - make up about 16 percent of the total carbon that sinks below the ocean's upper layers.
CHAMPAIGN, Ill. -- Scientists used accelerometers to track daily activity levels for a week in 89 adults with obesity or overweight and, in a series of tests, measured their ability to multitask and maintain their attention despite distractions. The study revealed that individuals who spent more sedentary time in bouts lasting 20 minutes or more were less able to overcome distractions.
