April 14, 2006
Beneath the waves of the South Pacific lies a volcanic realm nearly as strange as that featured in TV's hit drama Lost.
But instead of a mysterious island, scientists have found a bubbling submarine volcano whose weird features include a swirling vortex, a host of strange animals, and a fearsome zone of toxic waters dubbed the Moat of Death.
The volcano, described in this week's online edition of the Proceedings of the National Academy of Sciences, sits within the crater of a gigantic underwater mountain rising more than 4,500 meters (15,000 feet) from the ocean floor near the island of Samoa (see map).
The seamount, called Vailulu'u, is an active volcano, with a 2-mile-wide (3.2-kilometer-wide) crater. The cone rising within it has been dubbed Nafanua, for the Samoan goddess of war."

Massachusetts to require health insurance: "April 13, 2006
FREE PRESS NEWS SERVICES
BOSTON -- Gov. Mitt Romney signed a groundbreaking measure Wednesday that makes Massachusetts the first state to mandate universal health care.
Supported by Democrats and Republicans in the state Legislature, the law requires residents to buy health insurance by July 1, 2007, just as drivers must have automobile coverage.
It aims to help low-income families buy private health insurance with subsidies and penalizes those who don't get coverage. It will help extend coverage to about 500,000 people in the state who lack health insurance, or about one in 13 residents."

More Missing Link
Xinhua - English: " LOS ANGELES, April 12 (Xinhua) -- Fossils discovered in eastern Ethiopian desert are a missing link between our ape-man ancestors some 3.5 million years ago and more primitive hominids a million years older, according to a new study released on Wednesday.
The fossils are from the most primitive species of Australopithecus, known as Au. anamensis, and date from about 4.1 million years ago, reported researchers from Ethiopia, Japan, France and the United States.
The findings were published in an April 13 issue of the journal Nature.
The hominid Australopithecus has often been called ape-man because it walked on two legs unlike the great apes although it was short-statured, small-brained and big-toothed.
More primitive hominids in the genus Ardipithecus date from between 4.4 million and 7 million years ago and were much moreape-like, though they walked on two legs, too."

Super Earth
Top News | Reuters.co.ca: "WASHINGTON (Reuters) - A cold, heavy 'super-Earth' has been found orbiting a distant star, using a method that holds promise for detecting faraway planets that closely resemble our own, astronomers said on Monday.
The planet weighs 13 times as much as Earth and is orbiting a star about 9,000 light-years away. But instead of circling close to its star, as Earth does, this 'super-Earth' is about as distant from its star as Jupiter and Saturn are from the Sun.
An international team of scientists figured the new planet probably has a temperature of minus 330 degrees F (minus 201 C), making it one of the coldest planets detected outside our solar system.
The discovery is billed as a super-Earth because it is thought to be a rocky, terrestrial planet like Earth, even though it is much more massive.
The planet was detected by astronomers using a project called OGLE -- short for Optical Gravitational Lensing Experiment -- which looks for changes in light coming from distant stars."

Greenland's glaciers are melting into the sea twice as fast as previously believed, the result of a warming trend that renders obsolete predictions of how quickly Earth's oceans will rise over the next century, scientists said yesterday.
The new data come from satellite imagery and give fresh urgency to worries about the role of human activity in global warming.

JAKARTA, Indonesia - Describing it as the discovery of a �Lost World,� conservation groups and Indonesia on Tuesday said an expedition to one of Asia�s most isolated jungles had found several dozen new species of frogs, butterflies, flowers and birds.
�It�s as close to the Garden of Eden as you�re going to find on Earth,� Bruce Beehler, a Conservation International scientist who led the expedition, said in a statement.
�The first bird we saw at our camp was a new species,� he added. �Large mammals that have been hunted to near extinction elsewhere were here in abundance. We were able to simply pick up two Long-Beaked Echidnas, a primitive egg-laying mammal that is little known.�"

WASHINGTON (Reuters) -- A toothless, two-legged crocodile ancestor that walked upright and had a beak instead of teeth was discovered in the basement of New York's American Museum of Natural History, according to a report published on Wednesday.
The 210 million-year-old fossil had sat in storage at the museum for nearly 60 years and was found only by accident, the paleontologists said.
The animal is interesting because it closely resembles a completely unrelated dinosaur called an ostrich dinosaur that lived 80 million years later, they report in the Proceedings of the Royal Society B, a British science journal.
'A lot of people, from seeing (the film) Jurassic Park know what an ostrich dinosaur looked like,' said museum curator Mark Norell. 'This is a case of convergence with the ostrich dinosaur. It evolved more than once.'

Greenhouse Plants?
Science News Online:Vegetation may produce methane: Science News Online, Jan. 14, 2006:
"Greenhouse Plants? Vegetation may produce methane
Sid Perkins
Lab tests suggest that a wide variety of plants may routinely do something that scientists had previously thought impossible--produce methane in significant quantities.
Methane, like carbon dioxide, traps heat in Earth's atmosphere. Scientists have been studying natural sources of methane for decades but hadn't pegged plants as a producer, notes Frank Keppler, a geochemist at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. Previously recognized sources of methane include bacterial action in the digestive systems of ruminants such as cows and in the saturated soils of swamps and rice paddies. "

"NASA Probe Discovers Rolling Rocks, Gullies, Shifting Sands on Mars
Space - Discover magazine science:
"Sightings of shifting sand dunes, rolling boulders, and a dwindling polar ice cap in the past year demonstrate that the Red Planet is a far more dynamic world than scientists suspected.
Recently released images from the Mars Global Surveyor show before (left) and after views of the same crater, taken 13 months apart. During that time, falling boulders carved at least a dozen new tracks into the fine-grained material that lines the crater's wall.
NASA's orbiting Mars Global Surveyor revealed fresh gullies as long as three football fields on a dune west of the Hellas Basin. The same slope was smooth and unblemished in 2002. Scientists suspect that carbon dioxide trapped beneath the surface during winter vaporized when temperatures rose, releasing gas and causing sand to pour down the dune's face. The probe also snapped photos of boulders that had tumbled down a five-mile-wide crater, gouging shallow troughs not seen a year before. Possible causes include wind and seismic activity, although Mars's atmosphere is one-hundredth as dense as Earth's, and researchers have not yet found reliable evidence of Marsquakes. Meanwhile, carbon dioxide ice at the south pole has dwindled for three consecutive summers, suggesting long-term climate change is under way."

"The Incas didn't leave any written words behind, but they did leave behind khipus:knotted, colored, and twisted textile strings that seemed to serve as a record-keeping system for the largest state in the ancient New World. Until this year, the function of khipus was more presumed than proven. In August Harvard University anthropologist Gary Urton and his colleague Carrie Brezine reported the first clear signs of shared information embedded in 7 of 21 khipus from Puruchuco, an Incan palace and administrative center on the coast of Peru. 'For the first time we've been able to see khipus that are communicating with each other,' says Urton."

Liars Are Different
The Smirking Chimp: "According to a University of Southern California study conducted by Adrian Raine and Yaling Yang and published in the October issue of the British Journal of Psychiatry, a deceitful personality is due to a brain abnormality. Raine and Yang found that pathological liars have 26 percent more white matter and 14 percent less grey matter in their prefrontal cortex than do normal middling fibbers�most of us.
White matter is the portion of the brain that transmits information. An abundance of this tissue facilitates the quick, complex thinking involved in lying. Grey matter, on the other hand, processes information and mediates inhibitions (moral reasoning). An individual with a deficit of this tissue will not be impressed by the moral implications of a lie."

Woodward only confirms that the White House was trying to tell every sympathetic reporter in earshot that Valerie Plame was CIA and Joseph Wilson's wife. It doesn't help Scooter's case either even though Bob can't seem to remember much from two years ago. I had the feeling that Bob thought he would be some sort of Gonzo reporter when he released this information, but instead looks like the village idiot."
