Man Who Went To The Moon And Came Back An Artist

A Smithsonian National Air and Space Museum handout photo shows former astronaut Alan Bean in front of his easel at his art studio in Houston, Texas

From Yahoo News/AFP:

WASHINGTON (AFP) - - Forty years after Alan Bean became the fourth man to walk on the moon, the now 77-year-old former astronaut still likes to share his memories of space flight with a broad audience -- by painting them.

Bean decided to make the switch from astronaut to artist a dozen years after the Apollo 12 mission that took him to the moon in November 1969 and after spending two months in space in 1973 on board Skylab, and his souvenirs from both missions dominate his artwork.

When, at age 49, he dropped a bombshell on his bosses and colleagues at NASA, telling them that he was leaving to become a full-time painter, they wondered if he wasn't in the throes of lunacy.

From Science Daily:

ScienceDaily (July 19, 2009) — Suspending a life in time is a theme that normally finds itself in the pages of science fiction, but now such ideas have become a reality in the annals of science.

Cornell ecologist Nelson Hairston Jr. is a pioneer in a field known loosely as "resurrection ecology," in which researchers study the eggs of such creatures as zooplankton -- tiny, free-floating water animals -- that get buried in lake sediments and can remain viable for decades or even centuries. By hatching these eggs, Hairston and others can compare time-suspended hatchlings with their more contemporary counterparts to better understand how a species may have evolved in the meantime.

Arctic Mystery: Identifying The Great Blob of Alaska

Alaska's North Slope. Ccourtesy North Slope Borough

From Time Magazine:

A group of hunters aboard a small boat out of the tiny Alaska village of Wainwright were the first to spot what would eventually be called "the blob." It was a dark, floating mass stretching for miles through the Chukchi Sea, a frigid and relatively shallow expanse of Arctic Ocean water between Alaska's northwest coast and the Russian Far East. The goo was fibrous, hairy. When it touched floating ice, it looked almost black.

But what was it? An oil slick? Some sort of immense, amorphous organism adrift in some of the planet's most remote waters? Maybe a worrisome sign of global climate change? Or, as folks wondered who followed from faraway via the internet, was it something insidious and, perhaps, even carnivorous like the man-eating jello from the old Steve McQueen movie that inspired the Alaska phenomenon's nickname?

From L.A. Times:

The young scientists who created the Saturn V rocket that powered Aldrin and Armstrong to the moon on Apollo 11 in July 1969 were the unsung heroes in the space race with the Soviet Union.

It wasn't a young president's brash promise that enabled Neil Armstrong and Buzz Aldrin to take those first halting steps on the lunar surface 40 years ago Monday. Nor was it the courage of the astronauts themselves.

The success of America's big bet in space depended on the ability of young, unheralded engineers to build rocket engines that were both powerful enough and reliable enough to wrench the spacecraft from Earth's jealous grasp and send it winging to the lunar surface.

Space Station Toilet Breaks Down

From The BBC:

The main toilet has broken down on the International Space Station (ISS), currently home to a record 13 astronauts, Nasa said.

Mission Control told the crew to hang an "out of service" sign until the toilet can be fixed.

The crew of the shuttle Endeavour is confined to using the craft's loo. ISS residents are using a back-up toilet in the Russian part of the station.

If repairs fails, Apollo-era urine collection bags are on hand, Nasa said.

"We don't yet know the extent of the problem," flight director Brian Smith told reporters, adding that the toilet troubles were "not going to be an issue" for now.

Tough Microbe Has The Right Stuff for Mars

From Live Science:

Biologists have found microbes that live in the hottest, coldest, driest and most unpleasant places on Earth. Many of these bugs don't adapt well to new surroundings, but one microbe is remarkable for withstanding a wide range of conditions. This quality might make this unique organism suitable for adapting to life on Mars.

This ultimate survivor is called Methanosarcina barkeri. It is found in freshwater and marine sediments, and other places where oxygen is scarce. Because it breathes out methane, researchers are interested to see if it — or some other "methanogen" — could be responsible for the methane that was detected in the martian atmosphere in 2003.

Expiration Dates

From Organize Your Life:

Certain items in your house practically scream “toss me” when their prime has passed. That mysterious extra white layer on the Cheddar? A sure sign it needs to be put out of its misery. Chunky milk? Down the drain it goes.

But what about that jar of olives or Maraschino cherries that has resided in your refrigerator since before the birth of your kindergartner? Or the innumerable nonedibles lurking deep within your cabinets and closets: stockpiled shampoo and toothpaste, seldom-used silver polish? How do you know when their primes have passed?

With help from experts and product manufacturers, Real Simple (http://www.realsimple.com/) has compiled a guide to expiration dates. These dates are offered as a rough guideline. The shelf lives of most products depend upon how you treat them. Edibles, unless otherwise indicated, should be stored in a cool, dry place. (With any food, of course, use common sense.) Household cleaners also do best in a dry place with a stable temperature. After the dates shown, beauty and cleaning products are probably still safe but may be less effective.

10 Stunning (And Useful) Stats About Twitter

From Information Marketing Blog:

Last month a social media analytics provider named Sysomos released a comprehensive report on Twitter usage. The problem with most analysis on Twitter, though, is that it is limited by the minimal amount of data that Twitter collects. So, to fill the gaps, most reports do things like guessing gender based on real names or pulling data from keywords in people's biographic information. This often yields some questionable results - and the Sysomos report is not immune to this (for example, they find that 65% of Twitter users are under the age of 25, but base this on only the 0.7% of users who actually disclose their age).

Red Sky At Night: Heavens Turn Crimson Over Britain After Russian Volcano Erupts

(Click Image to Enlarge)
Shepherd's delight: A particularly fiery red sky over fields in Leicestershire last night after an eruption at Sarychev Peak in Russia unleashed a colourful mixture of ash and sulphur. When this 'volcanic aerosol' in the stratosphere mixes with the red light of the setting sun, it produces a vivid crimson hue

From The Daily Mail:

The night skies over Britain will turn a deep shade of crimson this week as the fallout from a Russian volcano blast hits the UK.

Millions of tonnes of dust, ash and sulphur dioxide were thrown up to 30 miles into the air when Sarychev Peak on Matua Island in the Kuril Archipelago erupted last month.

The blast created what experts call a ‘volcanic aerosol’ - a colourful mixture of ash and sulphur compounds - in the stratosphere.

This scatters an invisible blue glow which, when mixed with the red light of the setting sun, produces a ‘volcanic lavender’, or vivid crimson/violet hue.

The Genesis Enigma: How DID the Bible describe the evolution Of Life 3,000 Years Before Darwin?

Myth or divine inspiration: Was the book of Genesis a gateway into the evolution of life?

From The Daily Mail:

The revalation came to Professor Andrew Parker during a visit to Rome. He was in the Sistine Chapel, gazing up at Michelangelo's awesome ceiling paintings, when a realisation struck him with dizzying force.

'A Biblical enigma exists that is on the one hand so cryptic it has remained camouflaged for millennia, and on the other so obvious one cannot miss it.'

The enigma is that the order of Creation as described in the Book of Genesis, and so powerfully depicted in the Sistine Chapel by the greatest artist of the Renaissance, has been precisely, eerily confirmed by modern evolutionary science.

From New Scientist:

The Los Angeles metropolitan area belches far more methane into its air than scientists had previously realised. If other megacities are equally profligate, urban methane emissions may represent a surprisingly important source of this potent greenhouse gas.

Atmospheric researchers have long had good estimates of global methane emissions, but less is known about exactly where these emissions come from, particularly in urban areas.

Why Music Moves Us

From Scientific American:

New research explains music's power over human emotions and its benefits to our mental and physical well-being.

As a recreational vocalist, I have spent some of the most moving moments of my life engaged in song. As a college student, my eyes would often well up with tears during my twice-a-week choir rehearsals. I would feel relaxed and at peace yet excited and joyful, and I occasionally experienced a thrill so powerful that it sent shivers down my spine. I also felt connected with fellow musicians in a way I did not with friends who did not sing with me.

India Moon Probe 'Malfunctions'

From The BBC:

India's first mission to the Moon has experienced a technical problem, India's space research officials say.

A sensor of the unmanned Chandrayaan-1 spacecraft has "malfunctioned" and steps have been taken to ensure it is able to continue its work, they say.

But the possibility remains that the mission may have to be cut short.

Chandrayaan-1 was launched last October and is regarded as a major step for India as it seeks to keep pace with other space-faring nations in Asia.

Man And Machine The Real Legacy Of The Moon Race

From Boston.com:

For the millions who watched the grainy television feed from the moon on July 20, 1969, Neil Armstrong’s small step seemed to herald a new era. Arthur C. Clarke had already predicted that the children born during the Apollo missions would one day have their passports stamped on the moon; in the lunar spectacle, we glimpsed a brighter future in which humans would conquer the vastness of space and acknowledge their brotherhood on the pale blue dot of the home planet.

And yet, 40 years on, the Apollo program looks less like the start of a new era and more like an ancient culture that flourished briefly and then vanished, leaving only ruined towers, ritual costumes, and incomprehensible glyphs. In the decades since the last towering Saturn V tore through the night sky, NASA’s astronauts have spent their time on modest missions closer to home. The age of easy space travel that Apollo seemed to promise never materialized. And for all its technological marvels, Apollo bequeathed little to our material culture besides instant orange drink, freeze-dried ice cream, and the statuettes of the MTV video music awards.
