New evidence that vinegar may be natural fat-fighter
— 14:47 GMT | HealthResearchers in Japan are reporting new evidence that the ordinary vinegar - a staple in oil-and-vinegar salad dressings, pickles, and other foods - may live up to its age-old reputation in folk medicine as a health promoter. They are reporting new evidence that vinegar can help prevent accumulation of body fat and weight gain. Their study is scheduled for the 8 July issue of ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication…
'Milking' microscopic algae could yield massive amounts of oil
— 14:42 GMT | BiologyScientists in Canada and India are proposing a surprising new solution to the global energy crisis - 'milking' oil from the tiny, single-cell algae known as diatoms, renowned for their intricate, beautifully sculpted shells that resemble fine lacework. Their report appears online in the current issue of the ACS' bi-monthly journal Industrial Engineering and Chemical Research…
Mechanics: Ordinary meets quantum
— 14:37 GMT | TechnologyAt the quantum level, the atoms that make up matter and the photons that make up light behave in a number of seemingly bizarre ways. Particles can exist in 'superposition,' in more than one state at the same time (as long as we don't look), a situation that permitted Schroedinger's famed cat to be simultaneously alive and dead; matter can be 'entangled' - Albert Einstein called it 'spooky action at a distance' - such that one thing influences another thing, regardless of how far apart the two are…
Largest carnivorous dinosaur tooth in Spain described
— 14:32 GMT | Geology and palaeontologyResearchers from the Teruel-Dinopolis Joint Palaeontology Foundation have compared an Allosauroidea tooth found in deposits in Riodeva, Teruel, with other similar samples. The palaeontologists have concluded that this is the largest tooth of a carnivorous dinosaur to have been found to date in Spain…
No more test tubes on four feet? EPA moves toward animal-free toxicity tests
— 14:27 GMT | HealthThe U.S. Environmental Protection Agency (EPA) plans to switch to a new generation of animal-free tests for predicting the toxicity of chemicals to humans, according to an article scheduled for the 22 June issue of Chemical and Engineering News, ACS' weekly newsmagazine…
Study advises Chinese government to change fuel in millions of households
— 14:22 GMT | EnvironmentScientists in China are recommending that the Chinese government consider phasing out the direct burning of traditional chunks of coal in millions of households. It suggests that the government substitute coal briquettes and improved stoves for cooking and heating to help reduce the country's high air pollution levels. The recommendation stems from one of the first scientific studies showing that this approach is effective in improving air quality, including a 98 percent reduction in air pollution from tiny, inhalable particles of coal soot. Their study is scheduled for the 15 July issue of ACS' Environmental Science and Technology, a semi-monthly journal…
Many floors in U. S. homes have 'measurable' levels of pesticides
— 14:17 GMT | HealthInsecticides used in and around homes - including products voluntarily removed from the market years ago - were measured on the floors of U.S. residences, according to the first study large enough to generate national data on pesticide residues in homes. It is published in the 15 June issue of ACS' semi-monthly journal Environmental Science and Technology…
Better hearing with bone conducted sound
— 14:12 GMT | HealthNew technology to hear vibrations through the skull bone has been developed at Chalmers University of Technology. Besides investigating the function of a new implantable bone conduction hearing aid, Sabine Reinfeldt has studied the sensitivity for bone conducted sound and also examined the possibilities for a two-way communication system that is utilising bone conduction in noisy environments…

Ice volume of Switzerland's glaciers calculated
— 11:23 GMT | EnvironmentSwiss glaciers have lost a lot of ice in recent years due to increased melting. As temperatures climb, so do the fears that the glaciers could one day disappear altogether. Until now it could only be estimated approximately how big the ice volume in the Swiss Alps actually is and how it has changed in recent years. A team of scientists headed by Martin Funk, ETH-Professor at the Laboratory of Hydraulics, Hydrology and Glaciology (VAW) at ETH Zurich, however, has now developed a novel procedure for determining the ice volume of a glacier. Their results are presented in the current issue of Global and Planetary Change…
