Chemists devise easier new method for making a common type of building block for drugs
Ring-shaped chemical structures called saturated heterocycles are found in most FDA-approved drugs but are often difficult to create. Scripps Research chemists have just developed a surprisingly easy method for making many of these sought-after compo.....»»
Scientists find new ways to convert inhibitors into degraders, paving the way for future drug discoveries
Researchers have discovered ways to convert inhibitor-style targeted cancer drugs into small molecules known as degraders, which help destroy cancer-promoting proteins in cells......»»
Oxidant pollutant ozone removes mating barriers between fly species, study finds
Insect pheromones are odor molecules used for chemical communication within a species. Sex pheromones play a crucial role in the mating of many insects. Species-specific odors attract males and females of the same species. At the same time, they main.....»»
Novel UV broadband spectrometer improves air pollutant analysis
Sunlight has a major influence on chemical processes. Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of the substances present in the air. A well-known example is the formation of.....»»
New strategy for assessing the applicability of reactions
Chemists often develop and optimize new chemical reactions using so-called model systems, i.e., simple, easily accessible substrates. They then use up to around 100 other substrates as examples to show that the reaction works. This demonstration of v.....»»
EPA seeks to cut “Cancer Alley” pollutants
Chemical plants will have to monitor how much is escaping and stop leaks. Enlarge / An oil refinery in Louisiana. Facilities such as this have led to a proliferation of petrochemical plants in the area. (credit: Art Wager).....»»

The science of smell is fragrant with submolecules
A chemical that we smell may be a composite of multiple smell-making pieces. Enlarge (credit: Design Cells) When we catch a whiff of perfume or indulge in a scented candle, we are smelling much more than Floral Fantasy o.....»»
Chemical reactions can scramble quantum information as well as black holes
If you were to throw a message in a bottle into a black hole, all of the information in it, down to the quantum level, would become completely scrambled. Because in black holes this scrambling happens as quickly and thoroughly as quantum mechanics al.....»»
New micromaterial releases nanoparticles that selectively destroy cancer cells
Researchers have developed micromaterials made up only of proteins, capable of delivering over an extended period of time nanoparticles that attack specific cancer cells and destroy them. The micromaterials mimic natural secretory granules found in t.....»»
Two sex pheromone receptors for sexual communication found in the American cockroach
Sex pheromones are vital in facilitating the chemical communication that underpins insect courtship and mating behavior. Among female American cockroaches (Periplaneta americana), two key volatile sex pheromone components, periplanone-A (PA) and peri.....»»
Scientists harness chemical dynamics for complex problem solving
At the intersection of chemistry and computation, researchers from the University of Glasgow have developed a hybrid digital-chemical probabilistic computational system based on the Belousov-Zhabotinsky (BZ) reaction which can be used for solving com.....»»
Computational chemistry needs to be sustainable too, say researchers
A diverse group of computational chemists is encouraging the research community to embrace a sustainable software ecosystem. That's the message behind a perspective article published in the Journal of Chemical Theory and Computation. The authors disc.....»»
Team develops portable swept-source Raman spectrometer for chemical and biomedical applications
In 1928, Indian physicist Sir C. V. Raman and his colleague K. S. Krishnan discovered that when light interacts with matter, parts of the scattered light undergo changes in energy due to interaction with molecular vibrations, resulting in what is kno.....»»
Study describes zinc oxide nanoparticle strategy for inactivation of multidrug-resistant bacteria
