Using Cinnamon In the Production of Nanoparticles 126

Posted by samzenpus
from the what-about-the-brown-sugar? dept.
An anonymous reader writes "Scientists at the University of Missouri used cinnamon to replace almost all toxic chemicals needed for making gold nanoparticles used in electronics and healthcare products. Nanoparticle production requires the use of extremely dangerous and toxic chemicals. While the nanotechnology industry is expected to produce large quantities of useful nanoparticles in the near future, the entire production process could be detrimental to the environment."

+ - Cablegate: German criticisms of US data protection->

Submitted by natecochrane
natecochrane (1887566) writes "The US Ambassador to Germany scoffed at German criticisms of US data protection inadequacies, secret diplomatic despatches published to the internet on the weekend revealed. It was a case of German privacy adovcates' worst fears coming true. German politicians from the FDP centre-right faction of the ruling coalition were concerned last year that US safeguards were too lax and that information gathered on its nationals travelling to the US was "pointless" and compromised German interests. But the US ambassador to Germany told the US Secretary of State that the FDP had it wrong because it "has been out of power for over 10 years and lack experience tackling security issues in the internet age". Ambassador Murphy wrote that the "FDP appears not to fully grasp the transnational character of terrorism today and terrorists' increasing use of the Internet". But it appears the FDP understood more about data-leak prevention because it urged the US to appoint a data protection commissioner like the one Germany had."

+ - Aging Reversed in Mice after Telomerase Treatment 1

Submitted by
Hugh Pickens
Hugh Pickens writes "The Guardian reports that scientists claim to be a step closer to reversing the aging process after experimental treatment developed by researchers at Harvard Medical School turned weak and feeble old mice into healthy animals by regenerating their aged bodies. "What we saw in these animals was not a slowing down or stabilization of the aging process. We saw a dramatic reversal – and that was unexpected," says Ronald DePinho, who led the study. The Harvard group focused on a process called telomere shortening where each time a cell divides, the telomeres are snipped shorter, until eventually they stop working and the cell dies or goes into a suspended state called "senescence". Researchers bred genetically manipulated mice that lacked an enzyme called telomerase that stops telomeres getting shorter causing the mice to age prematurely and suffer ailments, including a poor sense of smell, smaller brain size, infertility and damaged intestines and spleens. When the mice were given injections to reactivate the enzyme, it repaired the damaged tissues and reversed the signs of aging raising hope among scientists that it may be possible to achieve a similar feat in humans – or at least to slow down the aging process. "This could lead to strategies that enhance the regenerative potential of organs as individuals age and so increase their quality of life," added DePinho cautioning that "whether it serves to increase longevity is a question we are not yet in a position to answer.""

+ - It's official: AMD will retire the ATI brand->

Submitted by J. Dzhugashvili
J. Dzhugashvili (1007075) writes "A little over four years have passed since AMD purchased ATI. In May of last year, AMD took the remains of the Canadian graphics company and melded them into a monolithic products group, which combined processors, graphics, and platforms. Now, AMD is about to take the next step: kill the ATI brand altogether. The company has officially announced the move, saying it plans to label its next generation of graphics cards 'AMD Radeon' and 'AMD FirePro,' with new logos to match. The move has a lot to do with the incoming arrival of products like Ontario and Llano, which will combine AMD processing and graphics in single slabs of silicon."

See sense 3:

Main Entry: 1American

Sense 4 is a particularly scary development, however.

Doesn't count. You're quoting a USAian dictionary.

The first time, it's a KLUDGE! The second, a trick. Later, it's a well-established technique! -- Mike Broido, Intermetrics
