Teamwork in a molecule
Chemists at the Friedrich Schiller University Jena have demonstrated the value of 'teamwork' by successfully harnessing the interaction between two gallium atoms in a novel compound to split the particularly strong bond between fluorine and carbon. T.....»»
Developing better nanopore technology
At the simplest of levels, nanopores are (nanometre-sized) holes in an insulating membrane. The hole allows ions to pass through the membrane when a voltage is applied, resulting in a measurable current. When a molecule passes through a nanopore it c.....»»
Examining the intricacies of ozone removal by deciduous forests
Ozone plays a vital role in Earth's climate system. In the stratosphere, which begins about six miles (9.7 kilometers) off the ground, ozone protects the planet from harmful ultraviolet radiation. Lower in the atmosphere, however, the molecule is an.....»»
Identifying an elusive molecule key to combustion chemistry
Researchers at the University of Pennsylvania and Argonne National Laboratory have made the most direct observation of a key intermediate formed during the breakdown of hydrocarbons in combustion and the atmosphere. Published in Science, this evidenc.....»»
Calling through the "DNA wire"
Proteins can communicate through DNA, conducting a long-distance dialog that serves as a kind of genetic "switch," according to Weizmann Institute of Science researchers. They found that the binding of proteins to one site of a DNA molecule can physi.....»»
Illuminating tissue formation through flourescence
Researchers at ETH Zurich have developed a molecule that fluoresces where new tissue is forming in the body. Alongside helping to detect tumors, the molecule could play a significant role in research of wound healing disorders......»»
How chemical reactions compute
A single molecule contains a wealth of information. It includes not only the number of each kind of constituent atom, but also how they're arranged and how they attach to each other. And during chemical reactions, that information determines the outc.....»»
Improving the observation of protein bonding
Researchers working with Oak Ridge National Laboratory developed a new method to observe how proteins, at the single-molecule level, bind with other molecules and more accurately pinpoint certain molecular behavior in complex physiological environmen.....»»
Researchers find fat burning molecule in mice
Linked to serious health problems including cancer, diabetes and cardiovascular disease, obesity affects more than a third of adults in the United States. Presently, there are few safe and effective nonsurgical therapeutic interventions available to.....»»
A single-molecule laser nanospectroscopy technique with micro-electron volt energy resolution
When molecules are excited, they can give rise to a variety of energy conversion phenomena, such as light emission and photoelectric or photochemical conversion. To unlock new energy conversion functions in organic materials, researchers should be ab.....»»
Studying chromosomal rearrangements in yeast reveals potential avenue for cancer therapy
Researchers from Osaka University have found that the attachment of a ubiquitin molecule to a protein called PCNA at the lysine 107 position causes gross chromosomal rearrangements. This lysine is located where two PCNA molecules interact, and the ub.....»»
A small molecule induces readthrough of cystic fibrosis CFTR nonsense mutations
An experimental drug suggests that a 'path is clearly achievable' to treat currently untreatable cases of cystic fibrosis disease caused by nonsense mutations. This includes about 11 percent of cystic fibrosis patients, as well as patients with other.....»»
Repairing hearts with deadly spider venom: Study
A potentially life-saving treatment for heart attack victims has been discovered from a very unlikely source - the venom of one of the world's deadliest spiders. A drug candidate developed from a molecule found in the venom of the Fraser Island (K'ga.....»»
Melanoma of the eye: Preclinical tests show path toward treatment
A preclinical study offers hope for treatment of uveal melanoma, a rare and deadly cancer of the eye. A small molecule inhibitor has been identified that dampens the potent drivers of this tumor. In mouse models, the inhibitor strongly limited primar.....»»
Human cells harness power of detergents to wipe out bacteria
Researchers have discovered that a molecule found within many of the body's cells kills germs by dissolving their protective membranes......»»
Metal-based molecules show promise against the build-up of Alzheimer"s peptides
In lab tests, researchers have created a metal-based molecule that inhibits the build-up of a peptide associated with Alzheimer's disease......»»
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.....»»
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......»»
