Pregnant and lactating women with COVID-19: Scant clinical research
New Rochelle, NY, May 18, 2020–Pregnant and breastfeeding women have been excluded from clinical trials of drugs to treat COVID-19, and as result, there is no safety data to inform clinical decisions. Such drugs include remdesivir according to a new…
‘Tantalizing’ clues about why a mysterious material switches from conductor to insulator
Tantalum disulfide is a mysterious material. According to textbook theory, it should be a conducting metal, but in the real world it acts like an insulator. Using a scanning tunneling microscope, researchers from the RIKEN Center for Emergent Matter Science…
Early visual experience drives precise alignment of cortical networks for binocular vision
Neural networks in the visual cortex of the brain do a remarkable job of transforming the patterns of light that fall onto the retina into the vivid sensory experience that we call sight. A critical element of this encoding process…
Stretch and flow: Research sheds light on unusual properties of well-known materials
Toothpaste, face creams, hair gel, mayonnaise, and ketchup are household items that most people don’t think twice about but, in terms of their flow behavior, they have unusual properties. They’re all elasto-visco-plastic (EVP) materials, which behave like solids when at…
