RUDN University chemists created anti-hantavirus drugs 5 times more efficient than existing drugs
2021-06-07
RUDN University chemists and their colleagues from Novosibirsk State University, Novosibirsk Institute of Organic Chemistry and The State Research Center of Virology and Biotechnology VECTOR have obtained a new class of compounds that inhibit the replication of the deadly Hantaan virus that affects blood vessels and internal organs of humans. The resulting substances were 5 times more effective than existing antiviral drugs. The results have been published Bioorganic & Medicinal Chemistry Letters. The Hantaan virus causes acute haemorrhagic fever with renal syndrome (HFRS). The disease ...

Space travel weakens our immune systems: Now scientists may know why

2021-06-07
Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their missions. One of the most striking observations from Apollo missions was that just over half of astronauts became sick with colds or other infections within a week of returning to Earth. Some astronauts have even experienced re-activation of dormant viruses, such as the chickenpox virus. These findings stimulated studies on the effects of weak gravity, or ...

Drop in convalescent plasma use at US hospitals linked to higher COVID-19 mortality rate

2021-06-07
A new study from researchers at Johns Hopkins Bloomberg School of Public Health and colleagues suggests a slowdown in the use of convalescent plasma to treat hospitalized COVID-19 patients led to a higher COVID-19 mortality during a critical period during this past winter's surge. U.S. hospitals began treating COVID-19 patients with convalescent plasma therapy--which uses antibody-rich blood from recovered COVID-19 patients--in the summer of 2020 when doctors were looking to identify treatments for the emerging disease. By the spring of 2021, doctors in the United States had treated over 500,000 COVID-19 patients with convalescent plasma. The use ...

Mice fathers pass down stress responses to offspring via sperm

Mice fathers pass down stress responses to offspring via sperm
2021-06-07
Male mice more susceptible to stress can pass down their behaviors to offspring via changes in their sperm's genetic code, according to new research published in JNeurosci. Stressful experiences alter gene expression, which parents can pass down to their offspring. But it was unclear if sperm itself transmits this information, or if behavioral cues between the parents play a larger role. Cunningham et al. tracked the stress response of male mice after ten days of chronic stress and sorted them into resilient and susceptible groups, based on the severity of their response. The offspring of resilient and control mice showed decreased stress behaviors ...

Health benefits of low protein-high carbohydrate diets depend on carb type

Health benefits of low protein-high carbohydrate diets depend on carb type
2021-06-07
Researchers at the University of Sydney's Charles Perkins Centre conducted the largest ever study of nutrient interactions by examining the health of mice on 33 different diets containing various combinations of protein to carbs, and different sources of carbohydrate. They found that a low-protein (10% of dietary energy), high-carbohydrate (70%) diet produced either the healthiest or unhealthiest metabolic outcomes of all 33 diets, depending on the kind of carbs. When carbs were made up mainly of resistant starch, a form of starch that is resistant to digestion and is fermented by bacteria in the gut, the low protein diet was the healthiest of all diets. When the ...

Gender bias is real for women in family-owned businesses

Gender bias is real for women in family-owned businesses
2021-06-07
A study examining gender bias and family-owned businesses found daughters were rarely encouraged nor received support to pursue entrepreneurship education while sons mostly did. Professors James Combs, Peter Jaskiewicz, and Sabine Raul from the Telfer School of Management uncovered new insights about how gender bias - the preference of a gender over the other - affects the succession strategy in multi-generational family firms. Their findings are published in the Journal of Small Business Management. When nurturing the next generation, entrepreneurial families often prepare their daughters and sons differently for their careers. The researchers noticed a common pattern in the stories shared by the next generation: Sons are often nurtured to ...

Stream of stars extends thousands of light-years across the Milky Way

2021-06-07
It's hard to see more than a handful of stars from Princeton University, because the lights from New York City, Princeton and Philadelphia prevent our sky from ever getting pitch black, but stargazers who get into more rural areas can see hundreds of naked-eye stars -- and a few smudgy objects, too. The biggest smudge is the Milky Way itself, the billions of stars that make up our spiral galaxy, which we see edge-on. The smaller smudges don't mean that you need glasses, but that you're seeing tightly packed groups of stars. One of the best-known of these "clouds" or "clusters" -- groups of stars that travel together -- is the Pleiades, also known as the Seven Sisters. Clusters are stellar nurseries where thousands of stars are born from clouds of gas and dust and then ...

A quantum step to a heat switch with no moving parts

2021-06-07
COLUMBUS, Ohio - Researchers have discovered a new electronic property at the frontier between the thermal and quantum sciences in a specially engineered metal alloy - and in the process identified a promising material for future devices that could turn heat on and off with the application of a magnetic "switch." In this material, electrons, which have a mass in vacuum and in most other materials, move like massless photons or light - an unexpected behavior, but a phenomenon theoretically predicted to exist here. The alloy was engineered with the elements bismuth and antimony at precise ranges based ...

CO2 sensors in two urban areas registered big drop in emissions during COVID-19 pandemic

2021-06-07
Carbon dioxide emissions in Los Angeles fell 33% in April of 2020 compared with previous years, as roads emptied and economic activity slowed due to the COVID-19 pandemic, according to a new study in Geophysical Research Letters. In the Washington, D.C./Baltimore region, emissions of carbon dioxide, or CO2, dropped by 34% during the same period. The study was led by scientists at NASA's Jet Propulsion Laboratory (JPL), the National Institute of Standards and Technology (NIST) and the University of Notre Dame. While the emissions reductions are significant, the method that scientists used to measure them may have the greater long-term impact. In both locations, scientists had previously ...

Researchers make new charge storage mechanism discovery

Researchers make new charge storage mechanism discovery
2021-06-07
Research between the University of Liverpool, UK and National Tsing Hua University (NTHU), Taiwan has revealed a new charge storage mechanism that has the potential to allow rechargeability within calcium-air batteries. In a paper published in the journal Chemical Science, Professor Laurence Hardwick from the University of Liverpool's Stephenson Institute for Renewable Energy (SIRE) and colleagues discover a distinctive form of charge storage at the electrode interface described as trapped interfacial redox. This new finding introduces a new mechanism of charge storage that could be harnessed in practical devices. Lead author of the paper, Yi Ting (Leo) Lu, is a joint PhD student in ...
