Synthesizing aryl sulfides from non-smelling, non-toxic compounds

Aryl sulfide, an aromatic compound in which sulfur is attached to an aryl (a functional group derived from an aromatic ring), is found in biologically active materials effective against asthma, Alzheimer's disease, and cancer. ...

Coated zinc sulfide nanoparticles are catalytically active

Ideally, a pigment should be resistant to corrosion under light irradiation—especially to UV radiation. It should also retain its white color in the long term. Today, the industry has already achieved all this with zinc ...

Small volcanic lakes tapping giant underground reservoirs

In its large caldera, Newberry volcano (Oregon, U.S.) has two small volcanic lakes, one fed by volcanic geothermal fluids (Paulina Lake) and one by gases (East Lake). These popular fishing grounds are small windows into a ...

Hydrogen sulfide helps maintain the drive to breathe

Effective regulation of breathing pattern is essential for many different mammalian processes such as energy production, metabolic regulation and even speech. Researchers have recently discovered that the body's production ...

Combining two tools would boost understanding of climate change

How much carbon dioxide, a pivotal greenhouse gas behind global warming, is absorbed by plants on land? It's a deceptively complicated question, so a Rutgers-led group of scientists recommends combining two cutting-edge tools ...
