Research published in suggests that children’s cognitive biases and anxiety symptoms encourage fear-enhancing behavior in parents, and not the other way around.Anxiety in youth is alarmingly common, sparking much research into its etiology. One prominent theory suggests that cognitive biases during information processing can help maintain anxiety in children. One such bias is confirmation bias, which refers to the tendency to look for information that confirms one’s viewpoint while ignoring alternate information.  Another is interpretation bias, which refers to the tendency to interpret...…Research published in suggests that children’s cognitive biases and anxiety symptoms encourage fear-enhancing behavior in parents, and not the other way around.Anxiety in youth is alarmingly common, sparking much research into its etiology.

A team of chemists from HSE University and the Zelinsky Institute of Organic Chemistry used molecular modelling to find out that two medications that have been known for a long time can be used to fight SARS-CoV-2. These are disulfiram, which is used to treat alcoholism, and neratinib, an experimental drug being used to treat breast cancer. The paper about the discovery has been available online since August 4, 2020, in the 4th issue of Mendeleev Communications journal.The structural elements of the virus that are less subject to mutation during its evolution should be chosen as a target...…A team of chemists from HSE University and the Zelinsky Institute of Organic Chemistry used molecular modelling to find out that two medications that have been known for a long time can be used to fight SARS-CoV-2.

a.k.a. what is the van der Waerden notation?Quantum field theory is hard, there’s no way to deny that. Especially when supersymmetry (SUSY) enters the game. In this article, we will go over the basic starting points on how to deal with spinors, as they usually appear in supersymmetric theories. In particular, there are three (yes, three) ways to denote the same expression when it involves spinors: index notation, compact index notation, and matrix notation. We will explore how they are related and how to switch between them.These notes are something I would have loved to read when I started...…a.k.a. what is the van der Waerden notation?Quantum field theory is hard, there’s no way to deny that.

In August 2014 a rocket launched the fifth and sixth satellites of the Galileo global navigation system, the European Union's $11-billion answer to the U.S.'s GPS. But celebration turned to disappointment when it became clear that the satellites had been dropped off at the wrong cosmic “bus stops.” Instead of being placed in circular orbits at stable altitudes, they were stranded in elliptical orbits useless for navigation.The mishap, however, offered a rare opportunity for a fundamental physics experiment.

A new fossil reveals how a mysterious ancient insect captured its meals.The discovery depicts a 99-million-year-old encounter between a “hell ant,” one of the earliest known ants, and its prey, an extinct relative of the cockroach. Preserved in amber, the ant, less than half the length of a dime, grasps the victim’s neck between two sharp mandibles and a hornlike protrusion on its head (pictured left, illustrated right).The find highlights hell ants’ strange anatomy. Whereas the mandibles of modern ants (as well as all adult insects) move horizontally, those of hell ants moved vertically,...…A new fossil reveals how a mysterious ancient insect captured its meals.The discovery depicts a 99-million-year-old encounter between a “hell ant,” one of the earliest known ants, and its prey, an extinct relative of the cockroach.
