Drugs called interferon betas are common treatments for multiple sclerosis. Interferon beta, a protein known to contain a zinc-binding pocket, is thought to reduce proinflammatory molecules in MS patients. But researchers now report in ACS Chemical Neuroscience that the molecule reduces the binding of three components — zinc, C-peptide and albumin — to red blood cells.
Urinary tract infections are common, yet can be tough to treat as the bacteria that cause them become resistant to many antibiotics. In ACS Central Science, researchers report a new molecule that inhibits drug-resistant bacteria in lab experiments, as well as in mice with pneumonia and UTIs.

Like a fire in a wall, fires in electric vehicle (EV) batteries burn unseen. Firefighters can squelch the visible flames in an EV fire, but chemicals inside the battery continue to burn because firefighters cannot reach the source. Researchers at Missouri S&T are working with mine operators and firefighting agencies to plan for and mitigate EV fire risks.
“With this study, we showed there is actually no microscopic evidence of zinc reinsertion into manganese dioxide, and what was previously thought to be indicators of recharging was from positively charged hydrogen ions being inserted in the manganese, not zinc.”
Researchers determine the structure and dynamics of proteins using NMR (Nuclear Magnetic Resonance) spectroscopy. Until now, however, much higher concentrations were necessary for in-vitro measurements of the biomolecules in solution than found in our body's cells. An NMR method enhanced by a very powerful amplifier, in combination with molecular dynamics simulation, now enables their detection and accurate characterization at physiological concentrations. This is reported by Dennis Kurzbach chemist at the University of Vienna and his colleagues in the journal "Science Advances". The team demonstrated their new method with the example of a protein that influences cell proliferation and thus also potential tumour growth.
Crystals consisting of wildly mixed ingredients - so-called high-entropy materials - are currently attracting growing scientific interest. Their advantage is that they are particularly stable at extremely high temperatures and could be used, for example, for energy storage and chemical production processes. An Empa team is producing and researching these mysterious ceramic materials, which have only been known since 2015.
Computer simulations are most often used as a guide, so chemists can more efficiently work out the exact details of a general reaction idea they have in mind — much like a compass helps guide an explorer efficiently to a destination on their map.
Despite being some of the most versatile building blocks in organic chemistry, compounds called carbenes can be too hot to handle. In the lab, chemists often avoid using these highly reactive molecules due to how explosive they can be. Yet in a new study, published today in the journal Science, researchers from The Ohio State University report on a new, safer method to turn these short-lived, high-energy molecules from much more stable ones.

Efficient adsorbents for industrial wastewater treatment are important to minimize potential environmental damage. In particular, organic dyes, as a significant group of industrial pollutants, are usually highly water soluble, non-degradable and many are toxic to carcinogenic. Changxia Li and Freddy Kleitz from the Faculty of Chemistry of the University of Vienna together with colleagues now presented a new approach to design an innovative composite material, consisting of a nanoporous, ultrathin covalent organic framework (COF) anchored on graphene, that is highly efficient at filtering organic pollutants from water. The study was published in “Angewandte Chemie”.

Researchers at the University of Wisconsin–Madison have described the way an enzyme and proteins interact to maintain the protective caps, called telomeres, at the end of chromosomes, a new insight into how a human cell preserves the integrity of its DNA through repeated cell division. DNA replication is essential for perpetuating life as we know it, but many of the complexities of the process — how myriad biomolecules get where they need to go and interact over a series of intricately orchestrated steps — remain mysterious.
Nonionic surfactants are molecules with both hydrophobic and hydrophilic components, which lets them interact both with hydrophilic liquids like water as well as hydrophobic liquids like oil. This surface-active property makes them invaluable in enhanced oil recovery, where they can be used to greatly increase oil yields. During the 72nd ACA meeting, Thomas Fitzgibbons, of Dow, will detail how nonionic surfactants behave under the high-pressure conditions found in oil wells; adding nonionic surfactants to the injection fluid can help in several ways.

JMIR Publications recently published "Diagnostic Accuracy of an At-Home, Rapid Self-test for Influenza: Prospective Comparative Accuracy Study" in JMIR Public Health and Surveillance which reported that rapid diagnostic tests (RDTs) for influenza used by individuals at home could potentially expand access to testing and reduce the impact of influenza on health systems. Improving access to testing could lead to earlier diagnosis following symptom onset, allowing more rapid interventions for those who test positive, including behavioral changes to minimize spread.
