A new University of Chicago study has found that the drug masitinib may be effective in treating COVID-19.
The drug, which has undergone several clinical trials for human conditions but has not yet received approval to treat humans, inhibited the replication of SARS-CoV-2 in human cell cultures and in a mouse model, leading to much lower viral loads.
Los Alamos, N.M., July 21, 2021--A team of scientists at Los Alamos National Laboratory propose that modulated quantum metasurfaces can control all properties of photonic qubits, a breakthrough that could impact the fields of quantum information, communications, sensing and imaging, as well as energy and momentum harvesting. The results of their study were released yesterday in the journal Physical Review Letters, published by the American Physical Society.
Targeted removals can be effective in suppressing the number of invasive lionfish found within protected coastlines around the Mediterranean Sea.
However, if they are to really be successful they need to be combined with better long-term monitoring by communities and conservationists to ensure their timing and location achieve the best results.
Those are the key findings of a new study, one of the first of its kind to examine the effectiveness of targeted lionfish removals from both an ecological and a socio-economic perspective.
Older adults may be slower to learn actions and behaviours that benefit themselves, but new research shows they are just as capable as younger people of learning behaviours that benefit others.
Researchers at the Universities of Birmingham and Oxford found that youngsters, in contrast, tend to learn much faster when they are making choices that benefit themselves.
Being more physically active and spending fewer hours per day sitting watching TV is linked to a substantially lower risk of developing obstructive sleep apnoea (OSA), according to new research published in the European Respiratory Journal [1]. It is the first study to simultaneously evaluate physical activity and sedentary behaviour in relation to OSA risk.
The remains of microscopic plankton blooms in near-shore ocean environments slowly sink to the seafloor, setting off processes that forever alter an important record of Earth's history, according to research from geoscientists, including David Fike at Washington University in St. Louis.
Fike is co-author of a new study published July 20 in Nature Communications.
Metabolic bone diseases, including osteoporosis, when bones lose their mass and become so fragile that they could be damaged while sneezing or under little stress, are called the silent epidemic of the 21st century. A person does not even know about his illness before the first symptom - it can be a fracture of the spine or the neck of the hip. According to statistics, every third woman and every fifth man after 50 have osteoporosis.
Spider silk is said to be one of the strongest, toughest materials on the Earth. Now engineers at Washington University in St. Louis have designed amyloid silk hybrid proteins and produced them in engineered bacteria. The resulting fibers are stronger and tougher than some natural spider silks.
Their research was published in the journal ACS Nano.
It's important to communicate about hard-to-see and complex environmental topics and issues with young people. In an article published in People and Nature, an international team reflects on the group's creation of the Shout Trout Workout, a lyric poem, comic, and music video for children aged 8-14 years old designed to entertain, engage, and enrich learning about migratory fishes and aquatic environments.
Results from a study published in Ibis show that how close Golden Eagles will fly to wind turbines depends on habitat suitability inside and outside of a wind farm. Also, the largest impact of wind farms was a loss of Golden Eagle habitat, which could be mitigated by including the study's findings in wind farm planning.
The study included data from 59 GPS-tagged Golden Eagles before and after turbine operation at 80 wind farms across Scotland.
A relaxing vacation on the beach frees us from many of the worries of everyday life. But the sand not only cleans the head and soul of vacationers - it also cleans the seawater.
Coastal sands are so-called biocatalytic filters. Hundreds of thousands of bacteria live on each grain of sand, and they process, for example, nitrogen and carbon from the seawater that flows through the sands. In this way, the sands act like giant, purifying filters. Much of what the seawater washes into the ground does not come out again.
In an article published in the American Journal of Kidney Diseases (AJKD), researchers found that among 176 studies on acute kidney injury, the Kidney Disease Improving Global Outcomes (KDIGO) definitions of kidney injury were inconsistently applied and 80% of studies did not define recovery of kidney function.
Millions of people in countries around the world could face an increased risk of malnutrition as climate change threatens their local fisheries.
New projections examining more than 800 fish species in more than 157 countries have revealed how two major, and growing, pressures - climate change and over-fishing - could impact the availability of vital micronutrients from our oceans.
An international group of researchers representing thousands of coral scientists across the globe is calling for new commitments and actions by the world's policymakers to protect and restore coral reefs.
In a paper presented July 20 at the International Coral Reef Symposium, the scientists said that the coming decade will likely offer the last chance for policymakers at all levels to prevent coral reefs "from heading towards world-wide collapse."
The female tsetse fly, which gives birth to adult-sized live young, produce weaker offspring as they get older, and when they feed on poor quality blood.
The study, carried out by researchers at the Universities of Bristol, Oxford and the Liverpool School of Tropical Medicine, was designed to measure how tsetse offspring health is influenced by their mothers' age, and how factors such as the mother's nutrition and mating experience might come into play.
