Diving Deep For A Living Fossil

From The New York Times:

For 33 years, Peter A. Rona has pursued an ancient, elusive animal, repeatedly plunging down more than two miles to the muddy seabed of the North Atlantic to search out, and if possible, pry loose his quarry.

Like Ahab, he has failed time and again. Despite access to the world’s best equipment for deep exploration, he has always come back empty-handed, the creature eluding his grip.

The animal is no white whale. And Dr. Rona is no unhinged Captain Ahab, but rather a distinguished oceanographer at Rutgers University. And he has now succeeded in making an intellectual splash with a new research report, written with a team of a dozen colleagues.

Four Years Later, New Orleans' Green Makeover

From Time Magazine:

After Hurricane Katrina flattened New Orleans exactly four years ago, on Aug. 29, 2005, the city emerged as an inadvertent symbol of global warming, the first American victim of climate change. Over 200,000 homes were destroyed during the Category 5 hurricane. But in the years since, the Crescent City has quietly embraced a new and unexpected role as a laboratory for green building. Sustainable development groups that range from the international nonprofit Global Green to earth-friendly celebrities like Brad Pitt descended on New Orleans, determined not just to build the city back, but to build it back green. "It's going to come back," says Matt Petersen, the president of Global Green USA. "But we want to build it better than it was before."

US Scientists Set To Reveal The True Colour Of Dinosaurs

From Independent:

A new technique that identifies the hue of ancient birds may help a Yale team with bigger beasts.

It is a question that has baffled the greatest scientific minds – and those of the average seven-year-old: what colour were dinosaurs?

Now a dramatic breakthrough in fossil examination has sparked a race to discover an answer that may satisfy the scientific community as well as anxious crayon-wielders. A research team at Yale University believes it has established a technique that can identify the colour of fossilised feathers and fur. Preliminary results suggest that the true colours of dinosaurs may soon be revealed.

From Technology Review:

Winemakers disappointed by organic methods have turned to biodynamics as the purest route to wine that's true to soil, grape, and climate.

For years the question in winemaking was how technology could make wine better. This was especially true if the wine was Californian. When California cabernet sauvignon bested the best of Bordeaux--in a legendary blind tasting, the "Judgment of Paris," convened by the English wine merchant Steven ­Spurrier--it was a moment of great national pride at the time of America's Bicentennial, and it was achieved in part because California winemakers had used technology in ways tradition-bound French winemakers would not. As California wine became respectable, Silicon Valley millionaires bought vineyards in Napa and Sonoma counties. California wine and tech soon enjoyed a happy marriage.

From Science Daily:

ScienceDaily (Aug. 31, 2009) — When bees sting, they pump poison into their victims. Now the toxin in bee venom has been harnessed to kill tumor cells by researchers at Washington University School of Medicine in St. Louis. The researchers attached the major component of bee venom to nano-sized spheres that they call nanobees.

In mice, nanobees delivered the bee toxin melittin to tumors while protecting other tissues from the toxin's destructive power. The mice's tumors stopped growing or shrank. The nanobees' effectiveness against cancer in the mice is reported in advance online publication Aug. 10 in the Journal of Clinical Investigation.

What Makes A Psychopath? Answers Remain Elusive

Psychopathic behavior can take many forms, not all of it violent. But some common themes underlie the condition, with pieces of a brain's emotional machinery missing. Psychopaths often lack empathy, guilt, conscience or the ability to show remorse. Image credit: stockxpert

Laser Tests Could Silence The Dentist's Drill

From New Scientist:

THE dentist's dreaded drill could become a medical relic thanks to laser tests which spot weaknesses in dental enamel in time to repair the surface before more drastic intervention is needed.

Dentists currently check for cavities with X-rays and metal probes, but these cannot detect weaknesses in the enamel while there is still a chance to repair it. David Wang, a graduate student at the University of Sydney in Australia, instead studied whether the propagation of sound waves through the enamel could provide an early warning (Optics Express, vol 17, p 15592).

White Europeans 'Only Evolved 5,500 Years Ago After Food Habits Changed'

Photo: People with pale skin like model Lily Cole may be descended from Europeans who dramatically changed their diets

From The Daily Mail:

People in England may have only developed pale skin within the last 5,500 years, according to new research.

Scientists believe that a sudden change in the diet around that time from hunter-gathering to farming may have led to a dramatic change in skin tone to make up for a lack of vitamin D.

Farmed food is lacking in vitamin D and while humans can produce it when exposed to the ultraviolet light in sunlight darker skin is far less efficient at it.

India Loses Moon Satellite Links

From The BBC:

All communication links with the only Indian satellite orbiting the Moon have been lost, India's space agency says.

Radio contact with the Chandrayaan-1 spacecraft was lost abruptly early on Saturday, said India's Bangalore-based Space Research Organization (Isro).

The unmanned craft was launched last October in what was billed as a two-year mission of exploration.

The launch was regarded as a major step for India as it seeks to keep pace with other space-faring nations in Asia.

Following its launch from the southern state of Andhra Pradesh, it was hoped the robotic probe would orbit the Moon, compile a 3-D atlas of the lunar surface and map the distribution of elements and minerals.

Regions with massive O stars show up as white or pink, while less massive B stars appear in blue. NGC 1566 is much richer in O stars than is NGC 6902. The images combine observations of UV emission by NASA's Galaxy Evolution Explorer spacecraft and H-alpha observations made with the Cerro Tololo Inter-American Observatory (CTIO) telescope in Chile.

From Science Daily:

ScienceDaily (Aug. 30, 2009) — An international team of researchers has debunked one of astronomy's long held beliefs about how stars are formed, using a set of galaxies found with CSIRO’s Parkes radio telescope.

When a cloud of interstellar gas collapses to form stars, the stars range from massive to minute.

Since the 1950s astronomers have thought that in a family of new-born stars the ratio of massive stars to lighter ones was always pretty much the same — for instance, that for every star 20 times more massive than the Sun or larger, you’d get 500 stars the mass of the Sun or less.

No obvious problems stood out, reports CBS News space analyst Bill Harwood.

But it will take engineers several more days to complete the normal (post-Columbia tragedy) assessment of launch imagery, laser scans carried out Saturday, and close-up photos of Discovery's belly during final approach to the International Space Station Sunday evening, before the heat shield is given a clean bill of health.

Why The Greenland And Antarctic Ice Sheets Are Not Collapsing

From Watts Up With That:

Global warming alarmists have suggested that the ice sheets of Greenland and Antarctica may collapse, causing disastrous sea level rise. This idea is based on the concept of an ice sheet sliding down an inclined plane on a base lubricated by meltwater, which is itself increasing because of global warming.

In reality the Greenland and Antarctic ice sheets occupy deep basins, and cannot slide down a plane. Furthermore glacial flow depends on stress (including the important yield stress) as well as temperature, and much of the ice sheets are well below melting point.

From Technology Review:

A breakthrough explores the challenges--and suggests the financial possibilities--of creating quantum networks.

Now he hopes to try the same stunt with bacteria hundreds of times larger. Meanwhile, Hans Mooij of the Delft University of Technology, with Seth Lloyd, who directs MIT's Center for Extreme Quantum Information Theory, has created quantum states (which occur when particles or systems of particles are superpositioned) on scales far above the quantum level by constructing a superconducting loop, visible to the human eye, that carries a supercurrent whose electrons run simultaneously clockwise and counterclockwise, thereby serving as a quantum computing circuit.
