Complex ocean behavior studied with 'artificial upwelling'
A team of scientists is studying the complex ocean upwelling process by mimicking nature - pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production.   view more (2008-09-03)

Scientists grow 'nanonets' able to snare added energy transfer
Using two abundant and relatively inexpensive elements, Boston College chemists have produced nanonets, a flexible webbing of nano-scale wires that multiplies surface area critical to improving the performance of the wires in electronics and energy applications.   view more (2008-09-03)

AgriLife Research breeder develops drought-tolerant corn
At the end of the day, drought tolerance in corn has to equate to good yields and good quality, not just good looks, said a Texas AgriLife Research scientist.   view more (2008-08-26)

Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight.   view more (2008-08-25)

Hormone replacement therapy improves sleep, sexuality and joint pain in older women

Major study shows significant quality-of-life benefits from HRT
A major international study of the effects of HRT use on quality of life has shown that HRT use can significantly improve well-being in women with menopausal symptoms such as hot flushes and night sweats.   view more (2008-08-22)

Getting to the Root of the Matter
Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop, and dazzling ornamental lies a... view more (2008-08-20)

Trees, forests and the Eiffel tower reveal theory of design in nature
What do a tree and the Eiffel Tower have in common? According to a Duke University engineer, both are optimized for flow. In the case of trees, the flow is of water from the ground throughout the trunk, branches and leaves, and into the air. The Eiffel Tower's flow carries stresses throughout the... view more (2008-08-14)

Green Roofs Differ in Building Cooling, Water Handling Capabilities
The first study to compare the performance of different types of green roofs has been completed by the Lady Bird Johnson Wildflower Center at The University of Texas at Austin and suggests that buyers shouldn't assume these roofs are created equal.   view more (2008-08-13)
