MOBILE, Alabama -- Oil is once again fouling the Gulf of Mexico around the Deepwater Horizon well, which was capped a little over a year ago.

Tuesday afternoon, hundreds of small, circular patches of oily sheen dotted the surface within a mile of the wellhead. With just a bare sheen present over about a quarter-mile, the scene was a far cry from the massive slick that covered the Gulf last summer.

Floating in a boat near the well site, Press-Register reporters watched blobs of oil rise to the surface and bloom into iridescent yellow patches. Those patches quickly expanded into rainbow sheens 4 to 5 feet across.

Each expanding bloom released a pronounced and pungent petroleum smell. Most of the oil was located in a patch about 50 yards wide and a quarter of a mile long.

A QuakeFinder network installation // Source: newsvine.com

Researchers at a Silicon Valley company are hard at work developing an experimental network of electromagnetic sensors that could predict large earthquakes as much as two weeks in advance; the theory behind the research is disputed, but Tom Bleier, the inventor and chief engineer behind project QuakeFinder, hopes to prove seismologists wrong.

The theory behind the research is disputed, but Tom Bleier, the inventor and chief engineer behind project QuakeFinder, hopes to prove seismologists wrong. Under the project, engineers will install roughly 200 five-foot tall sensors near fault lines in California to measure changes in underground magnetic fields and to detect electrically charged particles in the air.

Demonstrators shut down a BART station in July to protest the shooting death of 45-year-old Charles Hill.

In a controversial move that has riled up free speech advocates, San Francisco's Bay Area Rapid Transit (BART) subway system said it cut off cellphone signals at “select” stations in response to a planned protest this week.

“BART temporarily interrupted service at select BART stations as one of many tactics to ensure the safety of everyone on the platform,” the transit agency said in a statement on its website Friday.

BART said it took the actions because protesters said they “would use mobile devices to coordinate their disruptive activities and communicate about the location and number of BART Police.”

Demonstrators had planned a rally to bring attention to a number of transit police officer shootings, the latest one resulting in the death of 45-year-old Charles Hill, who was shot last month after a confrontation with officers.

The transit agency said protests during rush hour endangered the safety of commuters and employees.

Organisation for Economic Co-operation and Development (OECD) - January 17, 2011

In this project, public and private experts explore how to increase resilience to Future Global Shocks. The Project will generate options for governments to enhance capacity to identify, anticipate, control, contain and/or mitigate large disasters. It recognises that shocks can provide opportunities for progress, not just negative consequences. Amongst the inputs from which the final report will draw are six background papers and case studies on the following themes: Systemic Financial Risk; Pandemics; Cyber Risks; Geomagnetic Storms; Social Unrest and Anticipating Extreme Events.

Sensor mounted to bridge member // Source: gizmag.com

One of every four U.S. highway bridges has known structural problems or exceeded its intended life-span. Most only get inspected once every one or two years; University of Maryland researcher has developed a new sensor that measures indicators of a bridge's structural health, such as strain, vibration, flexibility, and development of metal cracks; the sensors are expected to last more than a decade, with each costing about $20

Millions of U.S. drivers cross faulty or obsolete bridges every day, highway statistics show, but it is too costly to fix all these spans or adequately monitor their safety, says a University of Maryland researcher who has developed a new, affordable early warning system.

This wireless technology could avert the kind of bridge collapse that killed thirteen and injured 145 along Minneapolis’ I-35W on 1 August 2007, he says — and do so at one-one-hundredth the cost of current wired systems.

A warning by the Hudson River near West 90th Street on Thursday. Millions of gallons of untreated waste spilled into the river - Monika Graff for The New York Times

New Yorkers have been warned to stay out of the Hudson and Harlem Rivers on one of the hottest weekends of the year after millions of gallons of untreated sewage discharged from Manhattan into the waterways because of a four-alarm fire that shut down one of the city’s largest sewage treatment plants.

The city's drinking water has not been impacted, officials said, but people have been cautioned not to swim or kayak on the waterways through at least Monday.

The New York City health department also declared large parts of the East River and the Kill Van Kull unfit for swimming through the weekend.

Local authorities did not expect any beaches in the area to be closed because of the spill.
