Common Houshold Detergents Good To Remove LeadAll-purpose detergents remove lead-contaminated dust from household surfaces just as effectively as high phosphate detergents and lead-specific cleaning products, according to new research scheduled for publication in the Jan. 15 issue of the American Chemical Society's Environmental Science and Technology journal.
The researchers, led by Roger D. Lewis, Ph.D., CIH, of the Saint Louis University School of Public Health, tested how well various detergents removed lead from three common household surfaces: vinyl flooring, wood and wallpaper. They determined that all-purpose floor detergents containing no phosphate did just as well as a more expensive lead-specific product and trisodium phosphate (TSP), a less environmentally friendly substance.

How Growth Hormones Work In PlantsBoth plant and animal growth is controlled by steroid hormones-signaling molecules that tell specific genes in cells to begin the physiological process of increasing cell size. Although these molecular managers operate similarly in plants and animals, the chain of events in regulating cellular functions appears to be very different in the two kingdoms. In animals, hormone reception begins in the nucleus of the cell. In plants, a steroid hormone family called brassinosteroids (BRs) start to work on the surface of the cell.
A bucket-brigade of activity then wins its way into the cell's nucleus to activate specific genes that tell the cell to grow. "We found a key component in this complex chain reaction in the cell nucleus that promotes cell growth," stated co-author Zhi-Yong Wang, of Carnegie's Department of Plant Biology in Stanford, CA. The research has important implications for the possibility of understanding how to manipulate the signaling machinery to increase plant growth and yield. The paper is published in the January 27, 2005, Science Express.........

Tibetan Plateau's secrets University of Alberta physicist who helped solve the age-old mystery of what keeps the highest plateau on Earth afloat, has added more pieces to the Tibetan puzzle. Dr. Martyn Unsworth has uncovered new research about the Tibetan Plateau-an immense region that for years has plagued researchers studying how the area became so elevated.
Several years ago, Unsworth and a team of researchers from China and the United States used low-frequency radio waves to determine that the mid-crust of the plateau is like "a big waterbed." The hot, molten rocks supporting the plateau are less dense than cold rocks, which means they rise up slowly, similar to how a hot-air balloon works. The discovery provides an explanation for how the whole of Tibet could rise up over millions of years.

View Chaotic Star BirthLocated 1,000 light-years from Earth in the constellation Perseus, a reflection nebula called NGC 1333 epitomizes the beautiful chaos of a dense group of stars being born. Most of the visible light from the young stars in this region is obscured by the dense, dusty cloud in which they formed. With NASA's Spitzer Space Telescope, researchers can detect the infrared light from these objects. This allows a look through the dust to gain a more detailed understanding of how stars like our sun begin their lives.
