MW189 blocks abnormal inflammation in the brain that is known to contribute to injury- and disease-induced neurologic impairments in a number of acute and chronic brain disorders. This study examining MW189 in healthy adult volunteers was performed by a collaborative team from UK, Duke University, and Northwestern University. The work by Van Eldik and the rest of the team is substantial as it is the first time MW189 had been tested in humans.
Physicists at ETH Zurich have developed the first high-repetition-rate laser source that produces coherent soft x-rays spanning the entire 'water window'. That technological breakthrough should enable a broad range of studies in the biological, chemical and material sciences as well as in physics.
A unique butterfly breeding experiment gave UC Berkeley researchers an opportunity to study the physical and genetic changes underlying the evolution of structural color, responsible for butterflies' iridescent purples, blues and greens. Using helium ion microscopy, the scientists discovered that a 75% increase in thickness of the chitin lamina of wing scales turned iridescent gold to shiny blue. They showed that knocking out a gene called optix achieves the same result: a bluer Common Buckeye.
The Belle II experiment started about one year ago. Physical Review Letters has now published the initial results of the detector. The work deals with a new particle in the context of dark matter, which accounts for about 25 percent of the universe.
Chloroquine, hydroxychloroquine and azithromycin are being used to treat and prevent COVID-19 despite weak evidence for effectiveness, and physicians and patients should be aware of the drugs' potentially serious adverse events, states a review in CMAJ (Canadian Medical Association Journal).
New research from Argonne National Laboratory takes a step toward the 'holy grail' of imaging: the ability to see the structure of a single, free-form molecule at atomic resolution.
As COVID-19 ravages the globe, researchers are working tirelessly to develop new diagnostics, vaccines and therapeutics. The question on the minds of scientists in many diverse fields is how they can help. Now, some researchers are publishing their thoughts on this topic in the form of editorials, perspectives and viewpoints in various ACS journals.
Someday, microbial cyborgs -- bacteria combined with electronic devices -- could be useful in fuel cells, biosensors and bioreactors. But first, scientists need to develop materials that not only nurture the microbes, but also efficiently and controllably harvest the electricity or other resources they make. Now, researchers reporting in ACS Applied Materials & Interfaces have developed one such material that enabled them to create a programmable 'biohybrid' system that conducts electrons from electricity-producing (exoelectrogenic) bacteria.
An international research team led by the Department of Physics and Astronomy at the University of Turku, Finland, mapped the interstellar magnetic field structure and interstellar matter distribution in the solar neighbourhood. The results of the study have been published in the esteemed European journal Astronomy & Astrophysics (A&A) in March, 2020.
Tiny fragments of plastic waste are dispersed throughout the environment, including the oceans, where marine organisms can ingest them. However, the subsequent fate of these microplastics in animals that live near the bottom of the ocean isn't clear. Now, researchers report in ACS' Environmental Science & Technology that lobsters can eat and break down some of this microplastic material, releasing even smaller fragments into the water that other deep-sea organisms could ingest.
