COVID-19 and America's response to it are likely to profoundly affect our families, work lives, relationships and gender roles for years, say 12 prominent scientists and authors who analyzed 90 research studies and used their expertise to evaluate our reaction to the pandemic and predict its aftermath.

The Paris Agreement in 2015 proposed a target to limit global warming to less than 2°C and pursue efforts to limit warming to less than 1.5°C. Since then, great efforts have been devoted to exploring the impacts of the 1.5°C and 2°C warming scenarios.

PHILADELPHIA - Multiple sclerosis (MS) is an autoimmune disorder that develops as immune cells attack the nervous system. T cells are a critical part of our immune system, with a complex array of subtypes - some drive the autoimmune response, while others try to suppress it.

ASPB is pleased to announce the publication of noteworthy research investigating water-saving alternatives for photosynthesis in temperate environments, which are likely to become hotter and drier in the future.

Women living in poorer households of Dhaka, Bangladesh are unwilling to give birth at maternal healthcare facilities.

A new study, published in PLOS ONE, found that the women living in Dhaka slums were reluctant to use institutionalised maternal health care for fear of having to make undocumented payments, unfamiliar institutional processes, lack of social and family support, matters of honour and shame, a culture of silence and inadequate spousal communication on health issues.

As much of Europe is engulfed by a second wave of Covid-19, and track and trace struggles to meet demand, modelling support tools are being increasingly used by policymakers to make key decisions. Most notably, models have been used to predict the Covid-19 R0 rate - the average rate of secondary infections from a single infection, which has formed the basis for many lockdown decisions across the UK.

Time crystals sound like something out of science fiction, but they may be the next major leap in quantum network research. A team based in Japan has proposed a method to use time crystals to simulate massive networks with very little computing power.

They published their results on October 16 Science Advances.

Our eyes are sensitive to only three spectral color bands (red, green, blue), and we all know that we can no longer distinguish colors if it becomes very dark. Spectroscopists can identify many more colors by the frequencies of the light waves, so that they can distinguish atoms and molecules by their spectral fingerprints. In a proof-of-principle experiment, Nathalie Picqué and Theodor Hänsch from the Max-Planck Institute of Quantum Optics (MPQ) and the Ludwig-Maximilian University (LMU) have now recorded broad spectra with close to one hundred thousand colors in almost complete darkness.

There has never been a more dangerous time than the COVID-19 pandemic for people with non-communicable diseases (NCDs) such as diabetes, cancer, respiratory problems or cardiovascular conditions, new UNSW Sydney research has found.

Among the adverse impacts of the pandemic for people with NCDs, the study found they are more vulnerable to catching and dying from COVID-19, while their exposure to NCD risk factors - such as substance abuse, social isolation and unhealthy diets - has increased during the pandemic.

Conventional plastic is made from oil. The production of plastic is not sustainable, and it can contain substances we know are dangerous if ingested.

In recent years, bioplastics have come onto the market as an alternative to conventional plastic. Bioplastic has some apparent advantages: it is usually made from recycled material or plant cellulose, it can be biodegradable - or both.

But a new study shows that it is not non-toxic.

Bioplastics are in fact just as toxic as other plastics, according to an article recently published in Environment International.

URBANA, Ill. - Extrusion is the norm in the pet and aqua feed industries, yet it remains unusual for swine feed in the United States. But the technology can improve energy and protein digestibility in pigs, according to research from the University of Illinois.

There is much debate surrounding the age of the Clovis -- a prehistoric culture named for stone tools found near Clovis, New Mexico in the early 1930s -- who once occupied North America during the end of the last Ice Age. New testing of bones and artifacts show that Clovis tools were made only during a brief, 300-year period from 13,050 to 12,750 years ago.

Stress is present everywhere, even bacteria and plant cells have to cope with it. They express various specific stress proteins, but how exactly this line of defense works is often not clear. A group of scientists headed by Professor Dirk Schneider of Johannes Gutenberg University Mainz (JGU) has now discovered a protective mechanism in cyanobacteria as well as in chloroplasts of plant cells: Complex ring structures formed by a protein attach to cell membranes and dissociate. Thereafter, the individual proteins spread out on the membrane surface and form a carpet structure.

Residents of U.S. counties with more social connections (measured as Facebook friends) to China or Italy - the first countries to report major COVID-19 outbreaks - were more likely to adhere to social distancing restrictions at the onset of the pandemic, according to a new study. The findings suggest that social networks supplied pandemic-related information that significantly influenced individual behavior. However, social ties also could have negative effects on pandemic-related behavior. For instance, areas within the U.S.

N-heterocycles are organic substances used in the chemical industry and medicine. To produce them, expensive catalysts made from noble metals are used. A chemist from RUDN University developed a nanocatalyst for N-heterocycles that consists of zinc oxide and niobium and can be obtained using orange peel without any additional chemical agents. The catalyst makes the reaction almost 100% effective, thus increasing the efficiency and reducing the cost of N-heterocycles production. The results of the study were published in the Catalysis Today journal.
