Cheaper, more efficient lighting for Africans with LED's
13 Apr, 2008 | CATEGORY: AfricaScience and Technology | SOURCE: Popular Mechanics | Comments
LED's can provide an affordable and swift means of developing the living standards of many Africans and populations in other Third world countries.
From the article:
"The number of people without adequate light is greater than the entire world population when Edison invented the light bulb."
"There are 1.7 billion impoverished people worldwide who burn kerosene for light. Fuel for this purpose costs $40 billion and emits 200 million tons of greenhouse gases per yearԗequivalent to the emissions from 30 million cars. While Americans spend a fraction of their income on light, people in the developing world devote 10 to 15 percent of theirs to itfor little return. Fuel lamps account for 17 percent of global lighting costs but provide less than one-tenth of one percent of global light output."
Scientists get sued in advance for the end of the world

You may have heard about the the Large Hadron Collider, or LHC, that is being constructed underneath about half of Europe (er..OK, France and Switzerland). When it is finished it will be the world's biggest particle collider and be able to do all sorts of interesting new things. For example - it will be able to create mini black holes. For a long time now there has been real concern amongst some physicists, futurists and members of the public that this machine could literally create a runaway black hole that would swallow the entire planet amongst other unimaginable accidents.
Last week a lawsuit was filed in Hawaii's U.S. District Court. The suit calls on the U.S. Department of Energy, Fermilab, the National Science Foundation and CERN to ease up on their LHC preparations for several months while the collider's safety was reassessed. Representatives at Fermilab in Illinois and at Europe's CERN laboratory, two of the defendants in the case, say there's no chance that the Large Hadron Collider would cause such cosmic catastrophes.
Cancer Free Mice

Scientists have accidentally discovered some mice that cannot get cancer, no matter how much they try to induce the disease in them, due to their remarkable white blood cells. Not only that, but once other mice are injected with the same white blood cells, they also cannot get cancer. Now scientist are looking for this cancer immunity in humans....
