Fluoride is good but too much of anything can be bad. However, a filter system developed in India using a medicinal herb is very, very good. The technology uses parts of the plant Tridax procumbens…

Researchers analyzed strains of mold fermented in sourdough bread and were able to isolate natural compounds that can help keep bread fresh without changing its flavor, resulting in a tastier loaf.…

Researchers employing a century-old observational technique have determined the precise configuration of humulones, substances derived from hops that give beer its distinctive flavor.  That…

Northwestern University graduate student Jonathan Barnes and colleagues are the first to permanently interlock two identical tetracationic rings that normally are repelled by each other. Some…

Researchers in Spain have mixed paper industry waste with ceramic material used in the construction industry and created a brick that has low thermal conductivity and so is a good insulator. …

A research team has tested a popular zinc hypothesis in paleo-ocean chemistry and concluded it is false. The fossil record indicates that eukaryotes, single-celled and multicellular organisms with…

Rose madder, a natural plant dye once prized throughout the Old World to make fiery red textiles, might be cool once again.  Chemists have developed a non-toxic and sustainable lithium-ion…
