Elevated dental plaque acid is a risk factor that contributes to cavities in children. But eating bran flakes with raisins containing no added sugar does not promote more acid in dental plaque than bran flakes alone, according to new research at the University of Illinois at Chicago. Some dentists believe sweet, sticky foods such as raisins cause cavities because they are difficult to clear off the tooth surfaces, said Christine Wu, professor and director of cariology research at UIC and lead...

U.S. government scientists say they've shown that water in hot dense environments acts as a catalyst, speeding chemical reactions without being consumed. Lawrence Livermore National Laboratory scientists said although the properties of pure water at high pressures and temperatures have long been studied, water in a reactive environment had never been researched. Lead scientist Christine Wu said she and her team studied the detonation of the high explosive pentaerythritol tetranitrate and...

The most abundant material on Earth exhibits some unusual chemical properties when placed under extreme conditions. Lawrence Livermore National Laboratory scientists have shown that water, in hot dense environments, plays an unexpected role in catalyzing complex explosive reactions. A catalyst is a compound that speeds chemical reactions without being consumed. Platinum and enzymes are common catalysts. But water rarely, if ever, acts as a catalyst under ordinary conditions. Detonations of...

WASHINGTON (Reuters) -- They may be sweet and sticky but raisins contain compounds that suppress bacteria responsible for cavities and gum disease, U.S. researchers said on Wednesday. While the researchers have not shown that people who eat raisins have healthier mouths, they identified five compounds known as phytochemicals in raisins that can be beneficial for teeth and gums. "Raisins are perceived as sweet and sticky and any food that contains sugar and is sticky is assumed to cause...

Compounds found in raisins fight bacteria in the mouth that cause cavities and gum disease, according to researchers at the University of Illinois at Chicago. "Our laboratory analyses showed that phytochemicals in this popular snack food suppressed the growth of oral bacteria associated with caries and gum disease," said Christine Wu, professor and associate dean for research at the UIC College of Dentistry and lead author of the study. Phytochemicals are compounds found in higher plants....


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.'
