Dried Plums As A Meat PreservativeTo help satisfy consumer demand for more natural food products, scientists at Texas A&M University are investigating dried plums as a meat preservative.
"We observed that dried plums, when pureed, actually have a very good antioxidant capacity," said Dr. Jimmy Keeton, professor of animal science and leader of the research at Texas A&M.

Fossils From Ancient Sea MonsterA fossil-hunting trip to celebrate a son's homecoming resulted in the recent discovery of an ancient sea monster in central Montana.
Believed to be approximately 70 million years old, its skull and lower jaw represent the first complete skull of a long-necked plesiosaur found in Montana, according to Montana State University experts. The skull is said to be one of the best specimens of its kind in North America.

Children's Belly Fat Increases More Than 65 PercentAbdominal obesity increased more than 65 percent among boys and almost 70 percent among girls between 1988 and 2004. The finding of growing girth is significant because abdominal obesity has emerged as a better predictor of cardiovascular disease and type 2 diabetes risk than the more commonly used Body Mass Index, a weight to height ratio that can sometimes be misleading.
As the first nationally representative study to document the increase........Go to the Media-blog (Added on 11/6/2006 4:33:47 AM)
T-ray breakthroughResearchers at the University of Bath, UK, and in Spain have said they have found a way to control the flow of terahertz radiation down a metal wire. Their findings are set out in a letter published in the current journal Physical Review Letters.

Where Seeds Store IronBiologists have learned where and how some plant seeds store iron, a valuable discovery for researchers working to improve the iron content of plants. Their research helps address the worldwide problem of iron deficiency and malnutrition in humans.
The team observed that iron is stored in the developing vascular system of the seed of Arabidopsis, a model plant used in research. In particular, iron is stored in the vacuole, a plant cell's........Go to the Science-blog (Added on 11/2/2006 8:54:06 PM)
Genes, Brain Chemicals And Complex Bee BehaviorUsing a new combination of techniques, U.S. and European scientists have identified 36 genes that encode brain chemicals likely to play a role in the complex behaviors of the honey bee--from working in and defending the hive to foraging, displaying and interpreting dance language. Understanding the jobs these chemicals, called neuropeptides, carry out in the honey bee will help researchers understand what they do in humans, the scientists said.........Go to the Science-blog (Added on 11/1/2006 8:32:12 PM)
First Sunrise on Hinode's instrumentsThe Hinode (formerly Solar-B) satellite, a joint Japan/NASA/PPARC mission launched on 22nd September 2006, reported its first observations of the Sun with its suite of scientific instruments on 31st October 2006.
The satellite was renamed 'Hinode' which is Japanese for Sunrise, which is most appropriate since Hinode will watch at close hand massively explosive solar flares erupting from the Sun's surface and rising into interstellar space.

Rock Climbing Does Not Increase Risk Of OsteoarthritisA study in the US has found there is no greater risk of osteoarthritis in rock climbers compared to non climbers, contrary to previous theory.

Study Shows Brain's Response To PleasingWe all have tastes we love, and tastes we hate. And yet, our "taste" for certain flavors and foods can change over time, as we get older or we get tired of eating the same old thing.

Mind of the BumblebeeRebecca Flanagan has probably come as close as a human can to reading the mind of a bumblebee.
Flanagan, a graduate student in biological sciences, and Associate Professor Jeffrey Karron are studying the behaviors of bees as they gather pollen - which plant species the bees forage on, which flowers they probe and in what order, and how many blooms they visit before moving on to another plant. In doing so, the bees make plant reproduction........Go to the Science-blog (Added on 10/29/2006 6:53:59 PM)
