Understanding the physics of granular materials is important in industries that handle and process large amounts of the materials, such as pills and powders in the pharmaceutical and food industries and sand in the construction business.

But the problem of how to model granular materials has perplexed physicists. In particular, they’d like to better understand how the temperature within an assemblage of granular material affects the system’s dynamics. That understanding will help

Anyone who made it to high school biology has learned about mitosis, or cell division. One cell divides into two, two into four and so forth in a process designed to pass on exact copies of the DNA in chromosomes to daughter cells. New research, by a University of Georgia team, shows how the genes that control this process are regulated.

The study is important for cancer research because the regulation of cell division goes awry in tumors and normal cell growth and behavior are lost. Unders

Advancement To Revolutionize Oral Drug Delivery Zengen, Inc. announced today that its revolutionary drug delivery technology will be used in the new Chloraseptic® Relief Strips(tm), the only medicated oral strip for the treatment of sore throat. Zengen’s proprietary technology is the first to use drug active ingredients in an oral strip. “We are excited to be part of the new generation of Chloraseptic products,” said R. Steven Davidson, chief executive officer of Zengen.

For the first time, astronomers are able to predict when major flares–enormous explosions that shoot hot gases into space–will erupt on stars outside our solar system, according to research to be published in an upcoming issue of the Astrophysical Journal.

The research is based on data from the longest-running continuous radio survey of flares produced by two types of binary systems, each containing a pair of stars under the influence of each other’s gravity. Stars in both binary sys

USDA Forest Service researchers at the Southern Institute of Forest Genetics (SIFG) in Saucier, MS are mapping genes in the pathogen that causes fusiform rust to provide future forest managers with more insurance against the damaging disease.

Fusiform rust, a fungus that forms spindle-shaped galls on the branches and stems of pine trees, is endemic to the southern U.S., occurring from Maryland to Florida and west to Texas and southern Arkansas. Attacking several southern pine species, the f

Over the last decade the market has had a tendency to value food products that are healthy and safe and encourage healthy lifestyles, with the added parameter that their associated production processes are environmentally sound. In the case of systems of cattle production the current and future aim is the obtaining of a quality product within an environmentally and economically sustainable framework.

Both objectives ultimately depend on animal feeding. The composition of the diet can have r
