Green roofs offer energy savings, storm-water control

An article in the November 2007 issue of BioScience describes green roofs -- roofs with a vegetated surface and substrate. Although more expensive to construct than a typical roof, a green roof can reduce energy costs during a building's lifetime and control storm-water runoff. Green roofs also provide havens for wildlife. Further research into their ecology and improved cost-benefit models could spur more widespread adoption of the technology.

1. 'Green' leather is in this season
   10-08-2007 · EurekAlert!
   Scientists in India have modified the leather tanning process making it far more eco-friendly. They have reduced the amount chemicals released by 82 percent and made an energy saving of nearly 40 percent. No loss of the leather quality was observed when compared with conventional tanning methods.

2. A really inconvenient truth: Divorce is not green
   12-03-2007 · EurekAlert!
   The data is in. Divorce is bad for the environment. A novel study that links divorce with the environment shows a global trend of soaring divorce rates has created more households with fewer people, has taken up more space and has gobbled up more energy and water. The findings of Jianguo "Jack" Liu and Eunice Yu at Michigan State University are published in this week's Proceedings of the National Academy of Sciences.

3. New Delft material concept for aircraft wings could save billions
   09-26-2007 · EurekAlert!
   Building aircraft wings with a special aluminium fiber combination makes them nearly immune to metal fatigue. The application of this technology, partly developed at Delft University of Technology, will lead to substantial savings. The unusual qualities of this special material can make a significant contribution to the development of truly energy-efficient, 'green' aircraft. Lower fuel consumption and reduction of maintenance costs could lead to worldwide savings as high as $100 billion.

4. New Developments in "Artificial Photosynthesis"
   03-27-2007 · Brookhaven National Laboratory
   Scientists at Brookhaven are trying to design catalysts inspired by photosynthesis, the natural process by which green plants convert sunlight, water, and carbon dioxide into oxygen and carbohydrates. The goal is to design a bio-inspired system that can produce fuels like methanol, methane, and hydrogen directly from water and carbon dioxide using renewable solar energy.

7. Researchers discover gene mutation thought to control energy levels
   09-18-2007 · EurekAlert!
   This study focused on the gene for AMPK (adenosine monophosphate-activated protein kinase), which controls the amount of energy in our cells by becoming active when fuel stores start to deplete, such as during exercise. The mutation discovered in individuals from two unrelated families caused a doubling of AMPK activity in muscle during rest, mimicking a state of exercise. This significant discovery appears in the Sept. 19 issue of the online, open-access journal, PLoS ONE.

   02-08-2008 · EurekAlert!
   A recent review of scientific literature concluded that low-calorie (or no-calorie) sweeteners may be helpful in resolving the obesity problem. The study by Bellisle and Drewnowski, published in the European Journal of Clinical Nutrition, evaluated a variety of laboratory, clinical and epidemiological studies on low-calorie sweeteners, energy density and satiety.

9. Mind the gap
   11-22-2006 · EurekAlert!
   Researchers have found a gap between water and a water-repelling surface that can give new insight into the way water and oil separate. By using high-energy X-rays at the ESRF, an international team defined the size and characteristics of this gap. The knowledge of the structure of a hydrophobic interface is important because they are crucial in biological systems, and can give insight in protein folding and stability.
