LONDON – Ireland is to ban the traditional lightbulb with householders forced to switch to new long-life low-energy bulbs. Legislation is being introduced to ban the sale of the normal incandescent lightbulb from January, 2009 so as the normal lightbulb breaks, householders will have to replace them with the more environmentally friendly long-life bulb which uses [...] PORTLAND, Ore. — Diatoms–single-celled phytoplankton (algae)–are one of the most plentiful life forms on Earth, accounting for 20 percent of the carbon dioxide removed from the environment each year. The mechanism they use–encasing themselves in patterned silicon dioxide shells as they fall to the bottom of oceans and lakes worldwide–removes as much carbon dioxide from [...] PORTLAND, Ore. — The hydrogen economy is getting a shot in the arm from a start-up that says its nanoparticle coatings could make hydrogen easy to produce at home from distilled water, and ultimately bring the cost of hydrogen fuel cells in line with that of fossil fuels. QuantumSphere Inc. says it has perfected the [...] A tiny chemical “brain” which could one day act as a remote control for swarms of nano-machines has been invented. The molecular device – just two billionths of a metre across – was able to control eight of the microscopic machines simultaneously in a test. PORTLAND, Ore. — Thermoelectric coolers and power generators were handed a 40-percent boost in performance recently by a nanotechnological reconstruction of a classic bulk material. The technique is suitable for mass production, according to its inventors at Boston College and the Massachusetts Institute of Technology (MIT). After 38 years, Israeli solves math code. A mathematical puzzle that baffled the top minds in the esoteric field of symbolic dynamics for nearly four decades has been cracked — by a 63-year-old immigrant who once had to work as a security guard. |
