You no longer need a snooty wine expert to identify a ’74 Pinot Noir from Burgundy – a handheld “electronic tongue” devised by European scientists will tell you the grape variety and vintage at the press of a button.

Designed for quality control in the field, the device is made up of six sensors which detect substances characteristic of a certain wine variety. Components such as acid, sugar and alcohol can be measured by this detection, and from these parameters it can determine the age and variety of the wine.

The tongue was invented by Cecilia Jiménez-Jorquera and colleagues from the Barcelona Institute of Microelectronics, Spain, and is reported in the Royal Society of Chemistry journal The Analyst.

Tiny fossilized teeth excavated from an Indian open-pit coal mine could be the oldest Asian remains ever found of anthropoids, the primate lineage of today's monkeys, apes and humans, say researchers from Duke University and the Indian Institute of Technology.

Just 9-thousandths of a square inch in size, the teeth are about 54.5 million years old and suggest these early primates were no larger than modern dwarf lemurs weighing about 2 to 3 ounces. Studies of the shape of the teeth suggest these small animals could live on a fruit and insect diet, according to the researchers.

"It's certainly the oldest anthropoid from Asia and India," said Richard Kay, a Duke professor of evolutionary anthropology who is corresponding author of a report in Proceedings of the National Academy of Sciences (PNAS).

Researchers at the University of Birmingham say they have uncovered new information about the way that we perceive fast moving, incoming objects – such as tennis or cricket balls.

The new research, published today in PNAS, studies why the human brain has difficulty perceiving fast moving objects coming from straight ahead; something that should be a key survival skill. The research has implications for understanding how top-class sportspeople make decisions about playing a shot but could also be important for improving road safety and for the development of robotic vision systems.

High-dose injections of vitamin C, also known as ascorbate or ascorbic acid, reduced tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian, and pancreatic cancers, researchers from the National Institutes of Health (NIH) report in the August 5, 2008, issue of the Proceedings of the National Academy of Sciences. The researchers traced ascorbate's anti-cancer effect to the formation of hydrogen peroxide in the extracellular fluid surrounding the tumors. Normal cells were unaffected.

Natural physiologic controls precisely regulate the amount of ascorbate absorbed by the body when it is taken orally. "When you eat foods containing more than 200 milligrams of vitamin C a day--for example, 2 oranges and a serving of broccoli--your body prevents blood levels of ascorbate from exceeding a narrow range," says Mark Levine, M.D., the study's lead author and chief of the Molecular and Clinical Nutrition Section of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), part of the NIH.

Dartmouth researchers writing in the journal Pediatrics have documented what they say are alarming numbers of young adolescents (age 10-14) who are exposed to graphic violence in movies rated R for violence. They found that these extremely violent movies were seen by an average of 12.5 percent of an estimated 22 million children age 10-14. One example, the R-rated "Scary Movie", was seen by an estimated 10 million children, or about 48 percent of 10-14 year olds.

Some scientific studies have established a connection between exposure to media violence and aggression and violence in children, including video games which some studies have said can lead to changes in attitudes and behavior as well as desensitization to actual violence.

Researchers from Boston University's Slone Epidemiology Center have found that approximately one in ten U.S. children uses one or more cough and cold medications during a given week. These findings appear in the August issue of the journal Pediatrics.

Pediatric cough and cold medications are widely marketed in the U.S. but surprisingly little is known about just how often they are used in children. This information is especially important in light of recent revelations that cough and cold medications are responsible for serious adverse events and even deaths among children.
