A mysterious blue molecule will help make better use of light energy
Researchers at IOCB Prague are the first to describe the causes of the behavior of one of the fundamental aromatic molecules, which fascinates the scientific world not only with its blue color but also with other unusual properties—azulene. Their c.....»»
"Crappier-than-crap" molecule exposed in overhaul of carbon-nitrogen-hydrogen chemistry
Russian researchers have explained why scientists studying crude oil and celestial chemistry—as well as certain down-to-earth matters—frequently come across some molecules incorporating carbon, nitrogen, and hydrogen but not other combinations of.....»»
Scientists probe the source of key hydrocarbons on Earth—and in space
Polycyclic aromatic hydrocarbons (PAHs) are a type of organic molecule that carry fused rings made of the chemical benzene. Scientists believe that PAHs are responsible for chemical processes that eventually lead to soot and other carbonaceous nanopa.....»»
Researchers present novel principle for nitric oxide-mediated signaling in blood vessels
Although a simple molecule, nitric oxide is an important signal substance that helps to reduce blood pressure by relaxing the blood vessels. But how it goes about doing this has long been unclear. Researchers at Karolinska Institutet in Sweden now pr.....»»
AI "nose" predicts smells from molecular structures
In a major breakthrough, scientists have built a tool to predict the odor profile of a molecule, just based on its structure. It can identify molecules that look different but smell the same, as well as molecules that look very similar but smell tota.....»»
Do artificial roosts help bats? Experts say more research needed
Artificial roosts for bats come in many forms—bat boxes, condos, bark mimics, clay roosts, and cinder block structures, to name a few—but a new conservation practice and policy article from researchers at the University of Illinois Urbana-Champai.....»»
Quantum computer unveils atomic dynamics of light-sensitive molecules
Researchers at Duke University have implemented a quantum-based method to observe a quantum effect in the way light-absorbing molecules interact with incoming photons. Known as a conical intersection, the effect puts limitations on the paths molecule.....»»
"Thermometer" molecule confirmed on exoplanet WASP-31b
Chromium hydride (CrH), a molecule that's relatively rare and particularly sensitive to temperature, is useful as a "thermometer for stars," according to astronomer Laura Flagg, because it's abundant only in a narrow range between 1,200–2,000 degre.....»»
