At 8:30 am PST on November 7th, the container ship M/V Cosco Busan struck the Bay Bridge in San Francisco Bay, California. A 100-foot gash in the hull of the vessel caused the release of an estimated 53,000 gallons of fuel oil (IFO 380) into the water (as of November 8, 2007). The vessel is no longer leaking product and is undergoing inspection.

More than 550,000 gallons of fuel oil have now spilled into straits connected to the Black Sea in what Russian officials are calling an environmental catastrophe.

The oil from a tanker cut in two during a storm at the weekend has killed an estimated 30,000 birds and there are warnings the effects of oil sinking to the sea bed could linger for years.

Chocolate was first produced by the ancients as a by-product of beer, suggests a new archaeological study. And evidence from drinking vessels left by the Mesoamericans who developed chocolate suggests that the source of chocolate, cacao, was first used 500 years earlier than thought.
 
 

Better Blood Vessels

New artificial blood vessels could help a wider range of patients

Technology Review
By Amanda Schaffer
November 09, 2007

Researchers have developed artificial blood vessels that are derived from human cells but appear to have long shelf lives and are unlikely to provoke an immune response. Such vessels could someday prove valuable to patients undergoing heart-bypass operations, dialysis, or other procedures in which portions of blood vessels, or vascular grafts, may be needed.
 
 

Time Slows When You’re on the Fly

Einstein was wrong. So, in essence, begins many a screed by some poor crackpot who aspires to be a physicist. Still, many legitimate physicists are willing to entertain the possibility that, in formulating his theories of relativity, Einstein didn’t get it exactly right. Some are looking for slight deviations from the prediction of his theory that might point to some deeper understanding of the universe. Alas, they’ll have to search even harder than before: A new experiment tests the stretching of time predicted by Einstein’s special theory of relativity and finds it spot on the money to 1 part in 10 million.
 
 

Superbug
Knocks Out Patient’s Defense

Mention resistant staph bacteria, and most people think about the almost invincible strains–officially called methicillin-resistant Staphylococcus aureus (MRSA)–that infect immunocompromised and sick people in hospitals. But in recent years, strains of MRSA that are even more virulent have started spreading outside hospitals and attacking perfectly healthy people (Science, 14 March 2003, p. 1639). Now, researchers say they have discovered how these bugs, which some see as a major public health threat, do their damage.

Sleeping
Giant Grows Restless

It’s a little like being in a room with the proverbial 800-pound gorilla–every little burp or twitch keeps you on your toes. That’s the way geologists feel about the caldera that sits under Yellowstone National Park. Scientists have detected accelerated activity on Earth’s surface that they think is originating from deep inside the geological structure known as a hot spot, and they are attempting to determine whether the giant volcano is growing restless or just turning over in its sleep.

China’s space science program took a major step when its first deep-space probe, Chang’e 1, began orbiting the Moon on November 5th. Two days later the 21⁄2-ton craft — named for the Chinese Moon goddess — dropped to a circular 125-mile-high orbit and prepared to begin its close-up studies of the surface.

Tropical Cyclone Guba reached Category 3 intensity in the Coral Sea late on Friday, according to weatherzone.com.au

The first named system of the season, Guba continued on a southward track off far north Queensland during Friday, at a pedestrian speed of about 4 km/h. Although slow moving, the cyclone intensified to produce wind gusts of up to 170 km/h, developing a clearly visible eye. By 4pm EST Guba had been upgraded to a Category 3 storm.

 
 

Bizarre Dinosaur Grazed Like a Cow, Study Says

A weird-looking dinosaur with a muzzle resembling a vacuum cleaner suggests long-necked plant-eaters such as the well-known Diplodocus didn’t always have their heads in the trees.

The findings are based on fossil analyses of a 110-million-year-old dinosaur found in the Sahara region of Africa by National Geographic Explorer-in-Residence Paul Sereno, a paleontologist at the University of Chicago, and his colleagues.

 
 

The Brain in Chronic Pain

Sophisticated brain-imaging studies suggest new ways to treat chronic pain.

Technology Review

November 15, 2007

Anyone who suffers from chronic pain knows that the experience is fundamentally different from enduring a scratch or a broken toe. Growing evidence from brain-imaging studies supports this notion: people with chronic pain show fundamental differences in both the structure and function of their brain. Scientists are now using these findings to develop and test new drugs created specifically for chronic pain.
 
 

Start-up makes electric power from motion

The company’s mission, in essence, is to apply the long-understood Faraday Principle–that putting a conductor near a magnetic field will produce voltage–to 21st century applications. Its initial target is to create a D-size battery for the military and then create batteries for consumer electronics.

Magnet and coil generators are typically too large for use in mobile electronics. The company’s technologists have been able to generate enough electricity to power small devices by manipulating the electromagnetic field that is produced when a coil moves near a magnet.
