Pakistan's liberal voice is going to be diminish, which is a dangerous precedent. The way in which killer of Punjab province governor was welcomed with so much rose explain how ultra conservative muslim is going influence a major portion of public thought. Recently after US issued a bounty on Hafiz Saeed when 'anti america' emotion with nationalist mood is at it's peak level simply fuel spread of 'mullah ' thought (orthodox & anti america anti india) on internet via social networking site. Therefore Zardari govt's little effort to check it is a good step.

Scientists Question Safety of New Airport Scanners 357

Posted by Soulskill from the don't-bombard-your-customers-with-radiation dept.
An anonymous reader sends this quote from a story at NPR about the accelerated deployment of new scanning machines at airports: "Fifty-two of these state-of-the-art machines are already scanning passengers at 23 US airports. By the end of 2011, there will be 1,000 machines and two out of every three passengers will be asked to step into one of the new machines for a six-second head-to-toe scan before boarding. About half of these machines will be so-called X-ray back-scatter scanners. They use low-energy X-rays to peer beneath passengers' clothing. That has some scientists worried. ... The San Francisco group thinks both the machine's manufacturer, Rapiscan, and government officials have miscalculated the dose that the X-ray scanners deliver to the skin — where nearly all the radiation is concentrated. The stated dose — about .02 microsieverts, a medical unit of radiation — is averaged over the whole body, members of the UCSF group said in interviews. But they maintain that if the dose is calculated as what gets deposited in the skin, the number would be higher, though how much higher is unclear."

19th-Century Photographer Captured 5,000 Snowflakes 80

Posted by kdawson from the more-science-than-art dept.
tcd004 writes "Wilson Bentley began photographing snowflakes in 1885, and managed to immortalize more than 5,000 crystals before his death in 1931. Now his images are widely recognized and highly sought after. At the age of 19, 'Snowflake' Bentley jury-rigged a microscope to a bulky bellows camera and took the first-ever photograph of a snowflake. Photography then, particularly microphotography, was much closer to science than art. In a 1910 article published in the journal Technical World, he wrote, 'Here is a gem bestrewn realm of nature possessing the charm of mystery, of the unknown, sure richly to reward the investigator." The video embedded at the link above touches on another long-forgotten piece of history: a sketch of the photographers who captured arial views of assemblages of tens of thousands of soldiers returning from WW-I, carefully choreographed and arranged to form a Liberty Bell, a Stature of Liberty, a US flag... as forgotten as the origin of the WW-I term razzle-dazzle.
