Male fruit flies found to transfer chemical to females to induce sleep, so they won"t mate with other males
A team of researchers from Bariloche Atomic Center and Fundación Instituto Leloir—IIBBA—CONICET, both in Argentina, has found that male fruit flies inject females with a chemical while mating that makes them sleep after sex so that they will not.....»»
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.....»»

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.....»»
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.....»»
