Scientists of Tomsk Polytechnic University jointly with their colleagues have synthetized a unique molecule of verdazyl-nitronyl nitroxide triradical. Only several research teams in the world were able to obtain molecules with similar properties. The molecule is stable. It is able to withstand high temperatures and obtains promising magnetic properties. It is a continuation of scientists' work on the search for promising organic magnetic materials. The research findings are published in the Journal of the American Chemical Society (IF: 14.612, Q1).
What does it take for people to commit to take action to promote social equality? And how might this differ for people from advantaged and disadvantaged groups?
COLUMBUS, Ohio - Although the United States is the only wealthy nation that doesn't guarantee paid leave to mothers or fathers after the arrival of a new child, Americans endorse providing paid time off for parents nearly as much as people from other countries.
About 82% of Americans support paid maternity leave, just slightly less than the 86% who support it in 26 wealthy nations, a new study shows.
Singularities such as those at the centre of black holes, where density becomes infinite, are often said to be places where physics 'breaks down'. However, this doesn't mean that 'anything' could happen, and physicists are interested in which laws could break down, and how.
Now, a research team from Imperial College London and the Cockcroft Institute and Lancaster University have proposed a way that singularities could violate the law of conservation of charge. Their theory is published in Annalen der Physik.
"Fit for 55": under this heading, the EU Commission will specify the implementation of the European Green Deal on 14 July. This refers to the more ambitious climate policy announced, with 55 instead of 40 percent emission reduction by 2030 (relative to 1990), and net-zero emissions in 2050. Coordination between the 27 EU states is expected to be difficult since unanimity is usually required here for sweeping changes.
LA JOLLA, CA--Researchers at La Jolla Institute for Immunology (LJI) have shed light on a process in immune cells that may explain why some people develop cardiovascular diseases.
Their research, published recently in Genome Biology, shows the key role that TET enzymes play in keeping immune cells on a healthy track as they mature. The scientists found that other enzymes do play a role in this process--but TET enzymes do the heavy lifting.
A study from UCLA neurologists challenges the idea that the brain recruits existing neurons to take over for those that are lost from stroke. It shows that in mice, undamaged neurons do not change their function after a stroke to compensate for damaged ones.
A stroke occurs when the blood supply to a certain part of the brain is interrupted, such as by a blood clot. Brain cells in that area become damaged and can no longer function.
A new study by UC Davis researchers confirms the low likelihood that SARS-CoV-2 contamination on hospital surfaces is infectious. The study, published June 24 in PLOS ONE, is the original report on recovering near-complete SARS-CoV-2 genome sequences directly from surface swabs.
BOSTON - At the recent 2021 Annual Scientific Sessions of the American Diabetes Association, researchers from Massachusetts General Hospital (MGH) presented positive updates on their trials of the bacillus Calmette-Guérin (BCG) vaccine to safely and significantly lower blood sugars.
After suffering a stroke, patients often are unable to use the arm on their affected side. Sometimes, they end up holding it close to their body, with the elbow flexed.
In a new study, Northwestern University and Shirley Ryan AbilityLab researchers have discovered that, in an attempt to adapt to this impairment, muscles actually lose sarcomeres -- their smallest, most basic building blocks.
Three years ago, Arthur Ashkin won the Nobel Prize for inventing optical tweezers, which use light in the form of a high-powered laser beam to capture and manipulate particles. Despite being created decades ago, optical tweezers still lead to major breakthroughs and are widely used today to study biological systems.
However, optical tweezers do have flaws. The prolonged interaction with the laser beam can alter molecules and particles or damage them with excessive heat.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have discovered that a specific chemical feature of a key protein known as tau may cause it to accumulate in the brain and trigger illnesses like Alzheimer's. They found that disulfide bonds on certain amino acids act to stabilize tau and cause it to accumulate, an effect that got worse with increased oxidative stress. The identification of chemical targets triggering tau accumulation may lead to breakthrough treatments.
The development of therapeutic drugs for inflammatory bowel disease, an intractable immune disease, and multiple sclerosis - an autoimmune disorder - is gaining traction. A research team from the Department of Life Sciences at POSTECH and a joint research team at ImmunoBiome Inc. have uncovered that a yeast-derived polysaccharide mixture inhibits the onset and progression of immune disorders.
Tsukuba, Japan - The COVID-19 pandemic has changed the way people eat, work, shop and go to school. Now, researchers from Japan have found surprising differences in the way people use healthcare services--including house calls from doctors.
In a study published this month in BMC Emergency Medicine, researchers from the University of Tsukuba have revealed that patterns in illness type and severity did change during the pandemic--with unexpected trends that may tell us about how people use health care services when personal contact carries inherent risk.
The contemporary materials industry raises the problem of creating a microscopic theory that allows to describe the observed physicochemical properties of a wide class of substances which are in demand in modern industry, medicine, and agriculture. A general and consistent theory will help to obtain reliable information from experimental data on the structure of matter, existing interactions and dynamic processes occurring in it, which can help in the synthesis and quality control of prospective materials.
