Scientists at Tokyo Institute of Technology (Tokyo Tech), Tohoku University, National Institute of Advanced Industrial Science and Technology, and Nippon Institute of Technology, demonstrated by experiment that a clean electrolyte/electrode interface is key to realizing high-capacity solid-state lithium batteries. Their findings could pave the way for improved battery designs with increased capacity, stability, and safety for both mobile devices and electric vehicles.
An extensive review of cephalopod fauna from the Northwest African Atlantic coast was performed by researchers from the University of Vigo (Spain) and the Spanish Institute of Oceanography (IEO). The study was based on the collections gathered in 1,247 bottom trawl stations carried out during ten multidisciplinary surveys in the Canary Current Large Marine Ecosystem (CCLME).
Every living organism has DNA, and every living organism engages in DNA replication, the process by which DNA makes an exact copy of itself during cell division. While it's a tried-and-true process, problems can arise.
Break-induced replication (BIR) is a way to solve those problems. In humans, it is employed chiefly to repair breaks in DNA that cannot be fixed otherwise. Yet BIR itself, through its repairs to DNA and how it conducts those repairs, can introduce or cause genomic rearrangements and mutations contributing to cancer development.
Quantum physics allows to make statements about the behaviour of a wide variety of many-particle systems at the atomic level, from salt crystals to neutron stars. In quantum systems, many parameters do not have concrete values, but are distributed over various values with certain probabilities. Often this distribution takes the form of a simple Gaussian bell curve that is encountered also in classical systems for example the distribution of balls in the Galton box experiment.
COLUMBUS, Ohio - Employees feel significantly less job distress if they work at companies that are open and transparent about the firm's finances, including budgets and profits, a new study found.
Researchers examining data from the U.K. found that at companies with more financial transparency, workers felt more secure in their jobs, more committed to their employers and - most significantly - said they had better relationships with their managers.
January 25, 2021 - What care do veterans need when recovering after suicide attempts? The answer may be different for women compared to men veterans, reports a qualitative study in Medical Care, part of a
X-rays are usually difficult to direct and guide. X-ray physicists at the University of Göttingen have developed a new method with which the X-rays can be emitted more precisely in one direction. To do this, the scientists use a structure of thin layers of materials with different densities of electrons to simultaneously deflect and focus the generated beams. The results of the study were published in the journal Science Advances.
Nature is full of colour. For flowers, displaying colour is primarily a means to attract pollinators. Insects use their colour vision not only to locate the right flowers to feed on but also to find mates. The evolutionary interaction between insects and plants has created complex dependencies that can have surprising outcomes. Casper van der Kooi, a biologist at the University of Groningen, uses an interdisciplinary approach to analyse the interaction between pollinators and flowers. In January, he was the first author of two review articles on this topic.
RUDN University linguists conducted comprehensive study of how Russian speakers perceive Greek sound
Linguists from RUDN University found out how Russian speakers differentiate between similar consonants of the Greek language and associate them with Russian sounds. The results of the study were published in the Speech Communication journal.
When it launches in the mid-2020s, NASA's Nancy Grace Roman Space Telescope will explore an expansive range of infrared astrophysics topics. One eagerly anticipated survey will use a gravitational effect called microlensing to reveal thousands of worlds that are similar to the planets in our solar system. Now, a new study shows that the same survey will also unveil more extreme planets and planet-like bodies in the heart of the Milky Way galaxy, thanks to their gravitational tug on the stars they orbit.
A new approach to mapping viral mutations that "escape" leading clinical antibodies has revealed mutations in the SARS-CoV-2 virus that allow it to evade treatments, including a single amino-acid mutation that fully escapes Regeneron's antibody cocktail. These maps, say the authors, demonstrate that prior characterization of escape mutations was incomplete. They will also help to enable immediate interpretation of the effects of the mutations cataloged by viral genomic surveillance, say the authors. Several antibodies are in use or under development as therapies to treat COVID-19.
Researchers have engineered an antibody that neutralizes SARS-CoV-2 with a potency that "rivals" current lead SARS-CoV-2 clinical neutralizing antibodies, and that also broadly neutralizes a range of clade 1 sarbecoviruses. Their antibody, ADG-2, studied in mice, represents a "promising candidate" for the prevention and treatment of not only COVID-19, they say, but also of future respiratory diseases caused by SARS-related coronaviruses.
During the first wave of the COVID-19 pandemic, nearly one in four families responded that they would be unlikely to bring their child to the Emergency Department if they had an emergency condition, according to a survey from Ann & Robert H. Lurie Children's Hospital of Chicago published in the journal Academic Emergency Medicine. Greater hesitancy to seek emergency care was found in families living in under-resourced communities, those who rely on public insurance and in families who are Black, Latinx or Asian.
Musical notes that sound pleasant together can form a harmony. These notes are usually in a special relationship with each other: when expressed as frequencies, their ratios result in simple fractions, such as four-thirds or three-halves. Similarly, a planetary system can also form a kind of harmony when planets, whose orbital period ratios form simple fractions, regularly attract each other with their gravity. When one planet takes three days to orbit its star and its neighbor takes two days, for example.
January 25, 2021 -- In a study to gain understanding of the future public health workforce, researchers at Columbia University Mailman School of Public Health and the Association of Schools and Programs of Public Health (ASPPH), conducted a large-scale analysis of the first employment outcomes of public health graduates and found that 78 percent were employed including 5 percent employed in fellowships and internships. Fifteen percent were continuing their studies; only 5 percent were not employed and job seeking.
