Panel sharply raises estimate of oil spilling into the Gulf to 60,000 barrels a day
A government expert panel raised yet again the estimate of the amount of oil spilling into the Gulf: the new estimate is 60,000 barrels a day, up from 30,000 last week; BP had only been able to collect about 15,000 barrels a day at its peak with the containment cap, and this new calculation, if it holds up, suggests that BP’s latest plans for capturing oil may not be adequate

DARPA aims to help U.S. Army snipers to, well, aim better
DARPA wants to help the U.S. Army’s snipers; in the works: programs aiming to give snipers the power to hit a target from 2,000 meters away in winds as high as forty miles per hour; making bullets that can change course in mid-air; and a stealth sniper scope that would make shooters all but invisible

BP capturing "less than half" of oil from spill
BP claims the cap placed on the broken well is capturing between 15,000 and 16,000 barrels a day, but this is less than half the 40,000 barrels of crude which keep gushing into the Gulf’s water; one Gulf drilling expert has warned that, in a worst-case scenario, it may take until Christmas to contain the leak fully

23-mile long oil plume approaches Florida's Treasure Coast
Scientists say that the most likely pathway for oil to reach the Florida Keys was for it to be pulled into a counterclockwise rotating frontal eddy in the northeast corner of the Loop Current, and then south along the eastern frontal zone of the Loop Current to the Dry Tortugas; a scientific research vessel finds an extensive oil slick that stretched about twenty miles along the southward flowing jet which merged with the northern front of the Loop Current

Web services could work with sensitive data -- without decrypting the data
A cryptographic method could allow cloud services to work with sensitive data without ever decrypting it; a novel technique could see future Web services work with sensitive data without ever being able to read it; several implementations of a mathematical proof unveiled last year will allow cryptographers to start making the proposal more practical.

Fibertect absorbent can clean Gulf oil spill's crude, holds toxic oil and mustard vapors
New material — raw cotton-carbon Fibertect — can absorb oil up to fifteen times its weight; the material can clean up crude oil and adsorb toxic polycyclic aromatic hydrocarbon vapors which sicken oil spill clean-up crew members; also, the material has been tested to successfully remediate mustard vapors such as those found from dumped munitions

Coast Guard solicits private sector ideas on how to stem spill, deal with consequences
“We’re adapting to an enemy that changes,” Coast Guard Adm. Thad Allen, the national incident commander for the oil spill, said; accordingly, in somewhat of an about-face, the Coast Guard last Friday began to solicit ideas from vendors, scientists, government laboratories, and nonprofits on how to stop, contain, and clean up the largest off-shore oil spill in U.S. history

40,000-plus barrels per day pouring into Gulf
Since the 20 April explosion of the Deepwater Horizon well, BP has insisted that the amount of oil being spilled into the gulf was no more than 5,000 barrels a day; U.S. government scientists yesterday corrected the company’s assertions, saying that amount is at least 40,000 barrels, if not more; the 1989 Exxon Valdez spilled 10.8 million gallons of oil into Alaska’s Prince William Sound; there are 42 gallons in a barrel of oil, so 40,000 barrels mean 1,680,000 gallons; this means that since 20 April, the BP well has released oil into the Gulf at a rate of one Exxon Valdez every 6.5 days; in other words, between 20 April and 3 June, when the well’s riser was cut, a quantity of oil equal to seven Exxon Valdez has been spilled into the Gulf

Robot assembles itself, then flies
Soldiers and first responders often find themselves in situations of surveillance or search and rescue, in which they may have to figure out on the fly what size and shape surveillance or search-and-rescue robot they need; Swiss researchers develop a flying platform made up of autonomous wheeled vehicle that lock together to share the task of controlled and autonomous flight; this self-sufficient wheeled DFA has another advantage: if one of the parts of which it consists breaks, the robot can reconfigure itself or substitute in a different part

BP's cost-cutting approach made well vulnerable, left company unprepared
Safety upgrades are critical but could mean higher prices for oil and gas; to cut costs, BP decided to install a continuous set of threaded casing pipes from the wellhead down to the bottom of its well; this leaves one blind to leaks that sneak up around the casing pipe, and the long string gives gas more time to percolate into the well; a preferred — and costlier — alternative in high-pressure deepwater is a “liner” design in which drillers install and then cement in place a short string of casing in the lower reaches of the well before casing the rest of the well

Next-generation HazMat boots made of leather
The rubber boots that emergency personnel wear when responding to situations where hazardous materials (HazMat) are present may be functional, but they are not very comfortable; with the availability of new textile materials and surface treatments, researchers are confident they can develop a comfortable — and functional — leather boot for use in both fire-fighting and HazMat operations
