Refrigerant in cars: Refreshingly cool, potentially toxic

The refrigerant R1234yf is being considered for use in air conditioning systems in cars. Chemists at Ludwig-Maximilians-Universitaet (LMU) in Munich now show that, in the event of a fire, it releases the highly poisonous ...

JILA team develops 'spinning trap' to measure electron roundness

JILA researchers have developed a method of spinning electric and magnetic fields around trapped molecular ions to measure whether the ions' tiny electrons are truly round—research with major implications for future scientific ...

An all-glass lab-on-a-chip

Lab-on-a-chip devices are microfluidic cells that incorporate pipes, reaction vessels, valves and a host of other implements typically found in laboratories. These components are typically carved into a flat plastic plate ...

New evidence on how fluoride fights tooth decay

In an advance toward solving a 50-year-old mystery, scientists are reporting new evidence on how the fluoride in drinking water, toothpastes, mouth rinses and other oral-care products prevents tooth decay. Their report appears ...

Herbal defluoridation of drinking water

Researchers in India have developed a filter system based on a medicinal herb, which they say can quickly and easily remove "fluoride" from drinking water. The technology described in the March issue of the International ...

Water treatments alone not enough to combat fluorosis in Ethiopia

Increased intake of dietary calcium may be key to addressing widespread dental health problems faced by millions of rural residents in Ethiopia's remote, poverty-stricken Main Rift Valley, according to a new Duke University-led ...

Scientists answer how bacteria fight toxic flouride

Yale researchers have uncovered the molecular tricks used by bacteria to fight the effects of fluoride, which is commonly used in toothpaste and mouthwash to combat tooth decay.
