Energy Tower: Power for 15 Earths? Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming. Those are pretty big claims, but the researchers from the Technion - Israel Institute of Science seem confident that the "Energy Tower" could be a major solution to the world's problems. They've been working on the concept since 1983, and together have spent more than 150 man-years researching, designing, testing, and analyzing. As project founder Professor Dan Zaslavsky explains, the Energy Tower works on the basic principle of convection: hot air rises and cold air falls. The 3,000-foot tall tower, with a diameter of 1200 feet, would take advantage of the heavy falling weight of cold air.
Ecology Drives the Worldwide Distribution of Human Diseases Identifying the factors underlying the origin and maintenance of the latitudinal diversity gradient is a central problem in ecology, but no consensus has emerged on which processes might generate this broad pattern. Interestingly, the vast majority of studies exploring the gradient have focused on free-living organisms, ignoring parasitic and infectious disease (PID) species. Here, we address the influence of environmental factors on the biological diversity of human pathogens and their global spatial organization. Using generalized linear multivariate models and Monte Carlo simulations, we conducted a series of comparative analyses to test the hypothesis that human PIDs exhibit the same global patterns of distribution as other taxonomic groups.
Why are we a nation of tree-huggers? 3 February 2011Last updated at 15:44 By Jon Kelly BBC News Magazine Plans to transfer ownership of many public forests in England have provoked a huge row.

Finnish inventor Heikki Kärnä is the man behind the Vipukirves Leveraxe and his aim was to redesign the axe using simple principles of physics to make it more efficient and safer. [Image Courtesy of Heikki Kärnä] This 1.9kg is more than a unique personal item, they are actually for sale but they do come at a price – €193.12. So what is it about this axe that would convince you to spend the little extra over a traditional design. A traditional axe is a simple wedge of metal on a handle that passes momentum on to the wood when it is struck; if there is enough momentum, the wood splits.
Pump Carbon Dioxide Underground - Science News GRAND RAPIDS, Mich. – A team of researchers representing government, industry and academia has launched a test project in which carbon dioxide produced by a natural gas processing plant is being disposed of by injecting it far beneath the ground. Officials announced Thursday that the test is under way at a site in Otsego County's Charlton Township, about 10 miles east of Gaylord in the northern part of the Lower Peninsula. It is one of more than 20 such projects taking place around the country.
Glacier Thermal Blanket Photos via MeteoLive In hopes of slowing the rate at which ice is melting in the mountains of northern Italy, officials have begun covering one their most threatened glaciers with insulating fabric, creating what is essentially a giant security blanket to help keep the ice from melting in the summer heat. It may sound a bit unusual, but tests have shown that the thermal blanket may be just the thing to save the region's glaciers from disappearing completely, for the time being, at least.Armed with nearly 970 thousand square feet of 4 millimeter thick thermal material, workers scramble to cover the highly threatened Presena glacier to protect it from the sun's ultraviolet rays.
