• Crystal structures in super slow motion
    on January 22, 2021 at 8:44 pm

    Laser beams are used to change the properties of materials in an extremely precise way. However, the underlying processes generally take place at such unimaginably fast speeds and at such a small scale that they have so far eluded direct observation. Researchers have now managed to film, for the first time, the laser transformation of a crystal structure with nanometer resolution and in slow motion in an electron microscope.

  • NSAIDs might exacerbate or suppress COVID-19 depending on timing, mouse study suggests

    New research shows that non-steroidal anti-inflammatory drugs (NSAIDs) reduced both antibody and inflammatory responses to SARS-CoV-2 infection in mice.

  • PTSD link to pandemic fears
    on January 22, 2021 at 3:20 pm

    A new study of 1040 online participants from five western countries explores people's response to the stresses of the escalating pandemic, finding more than 13 percent of the sample had post-traumatic stress disorder (PTSD) related symptoms consistent with levels necessary to qualify for a clinical diagnosis.

  • Cargo delivery by polymers
    on January 22, 2021 at 3:16 pm

    Degradable, bio-based polymers offer options for chemical recycling, and they can be a tool to store and release useful molecules. Scientists have developed a class of sugar-based polymers that are degradable through acid hydrolysis. The researchers also integrated 'cargo' molecules in the polymer, which are designed to split off after polymer degradation.

  • Rhesus macaques develop promising immune response to SARS-CoV-2
    on January 22, 2021 at 1:49 pm

    In a promising result for the success of vaccines against COVID-19, rhesus macaque monkeys infected with the human coronavirus SARS-CoV-2 developed protective immune responses that might be reproduced with a vaccine.
