Signaling molecule may help prevent Alzheimer"s disease
The main driver of Alzheimer's disease is excessive inflammation in the brain that is triggered by cells called astrocytes and microglia in response to high levels of amyloid beta deposits and tau tangles. New research reveals that a subset of astroc.....»»
Small molecule plays outsize role in controlling nanoparticle
Ligands are much like nanosized barnacles, binding to many kinds of surfaces. This form of adsorption is crucial for a range of chemical processes, from purification and catalysis to the design of nanomaterials......»»
Examining mRNA transcription difficulties
The corona pandemic has ensured that the term "mRNA" is now also known to a large public beyond laboratories and lecture halls. However, the molecule is much more than an important component of a successful vaccine against the SARS-CoV-2 virus. "mRNA.....»»
Simulating microswimmers in nematic fluids
Artificial microswimmers have received much attention in recent years. By mimicking microbes which convert their surrounding energy into swimming motions, these particles could soon be exploited for many important applications. Yet before this can ha.....»»
Vaccines grown in eggs induce antibody response against an egg-associated glycan, study finds
Researchers have found that viral vaccines grown in eggs, such as the H1N1 flu vaccine, produce an antibody response against a sugar molecule found in eggs, which could have implications for the effectiveness of these vaccines......»»
New clues to why there"s so little antimatter in the universe
Imagine a dust particle in a storm cloud, and you can get an idea of a neutron's insignificance compared to the magnitude of the molecule it inhabits......»»

This molecule is made from sugar, shaped like a doughnut, and formed using light
A process using a light-sensitive chemical can drastically reduce cost and energy consumption to produce gamma-cyclodextrin, a compound that is widely used in manufacturing, according to a Dartmouth study......»»
"Nanodecoy" therapy binds and neutralizes SARS-CoV-2 virus
Nanodecoys made from human lung spheroid cells (LSCs) can bind to and neutralize SARS-CoV-2, promoting viral clearance and reducing lung injury in a macaque model of COVID-19. By mimicking the receptor that the virus binds to rather than targeting th.....»»
Genetically engineered nanoparticle delivers dexamethasone directly to inflamed lungs
Nanoengineers at the University of California San Diego have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they're needed. As a proof of concept, the researchers filled the nanopa.....»»
Ozone pollution has increased in Antarctica
Ozone is a pollutant at ground level, but very high in the atmosphere's "ozone layer," it absorbs damaging ultraviolet radiation. Past studies have examined ozone levels in the Southern Hemisphere, but little is known about levels of the molecule in.....»»
Machine learning aids in materials design
A long-held goal by chemists across many industries, including energy, pharmaceuticals, energetics, food additives and organic semiconductors, is to imagine the chemical structure of a new molecule and be able to predict how it will function for a de.....»»
Study shows how permafrost releases methane in the warming Arctic
