From Florida Today:
Reliability must grow tenfold in new rockets.
CAPE CANAVERAL — President Barack Obama faces decisions that will set safety levels for American astronauts launching on space expeditions for decades to come.
Congress will hear this week from NASA officials, proponents of commercial crew transportation and independent safety experts. No current NASA astronauts are scheduled to testify Wednesday before the House subcommittee on space and aeronautics.
But documents obtained by FLORIDA TODAY through the Freedom of Information Act show exactly where the actual risk-takers stand.

Legends Of Vietnam: Super Tweet
From Air And Space Smithsonian:
Yeah. The A-37 was small. So was Napoleon.
Looking for Mach-busting splendor in million-dollar wonders from the heavies of the U.S. military-industrial complex? This ain't it. The A-37 Dragonfly was a waist-high, subsonic light attack aircraft that could lift its own weight in fuel and armaments, built by a manufacturer known for civilian pleasure craft. You could get a half-dozen for the price of a single F-4. The A-37 brought jet-propelled combat in Vietnam down from rarefied heights to the low-and-slow—where the acrid haze of rice-burning season permeated the unpressurized cockpit and you plucked bullets from Viet Cong small arms out of the armor plate under your seat after a mission. Its claim to fame?

Clue To Mystery Of How Biological Clock Operates on 24-Hour Cycle
From Science Daily:
Science Daily (Nov. 29, 2009) — How does our biological system know that it is supposed to operate on a 24-hour cycle? Scientists at the Hebrew University of Jerusalem have discovered that a tiny molecule holds the clue to the mystery.
Human as well as most living organisms on earth possess circadian a (24-hour) life rhythm. This rhythm is generated from an internal clock that is located in the brain and regulates many bodily functions, including the sleep-wake cycle and eating.

Surprise! Your Skin Can Hear
From Live Science:
We not only hear with our ears, but also through our skin, according to a new study.
The finding, based on experiments in which participants listened to certain syllables while puffs of air hit their skin, suggests our brains take in and integrate information from various senses to build a picture of our surroundings.
Along with other recent work, the research flips the traditional view of how we perceive the world on its head.

2012: Six End-of-the-World Myths Debunked
A city slides into the sea in a scene from the movie 2012, to be released November 13, 2009. The movie's end-of-the-world plot is based on largely discredited prophecies dubiously attributed to the ancient Maya, experts say. Image courtesy Columbia Tristar Marketing Group
From National Geographic:
The end of the world is near—December 21, 2012, to be exact—according to theories based on a purported ancient Maya prediction and fanned by the marketing machine behind the soon-to-be-released 2012 movie.
But could humankind really meet its end in 2012—drowned in apocalyptic floods, walloped by a secret planet, seared by an angry sun, or thrown overboard by speeding continents?

The Great Climate Change Science Scandal
From Times Online:
Leaked emails have revealed the unwillingness of climate change scientists to engage in a proper debate with the sceptics who doubt global warming.
The storm began with just four cryptic words. “A miracle has happened,” announced a contributor to Climate Audit, a website devoted to criticising the science of climate change.
“RC” said nothing more — but included a web link that took anyone who clicked on it to another site, Real Climate.
There, on the morning of November 17, they found a treasure trove: a thousand or so emails sent or received by Professor Phil Jones, director of the climatic research unit at the University of East Anglia in Norwich.
Jones is a key player in the science of climate change. His department’s databases on global temperature changes and its measurements have been crucial in building the case for global warming.

Devils’ Advocates
From Air And Space Smithsonian:
Some people go to Las Vegas to gamble, others to learn about Mars.
“Three, two, one, now!” Just seconds ago Asmin “Oz” Pathare was sitting under a beach umbrella in the baking heat, gazing off into the distance—now he has jumped to his feet behind his camera tripod and is on his walkie-talkie with fellow scientist Steve Metzger, who’s a couple hundred yards away. At the count of zero, they both trigger their shutters to get a stereo picture of the devil headed our way.

trees grow in an area that was once covered in ice.
Whether the causes of the warming are due to natural rhythms or down to man continues to provide fierce debate. But scientists say they give a face to global warming.
From The Daily Mail:
These revealing photographs show giant glaciers are melting away as the world slowly warms up.
Pictured over the last 106 years, the huge lumps of ice have been slowly melting and creeping back into the mountains.
Where there was ice many metres thick, there is now debris, sediment and stagnation.
In some cases the glaciers have disappeared altogether and the land they once covered has become pasture, lake or woodland.

Science Untarnished By 'Climategate,' U.N. Says
From CNET News:
LONDON--The head of the U.N.'s panel of climate experts rejected accusations of bias on Thursday, saying a "Climategate" row in no way undermined evidence that humans are to blame for global warming.
Climate change skeptics have seized on a series of e-mails written by specialists in the field, accusing them of colluding to suppress data which might have undermined their arguments.
The e-mails, some written as long as 13 years ago, were stolen from a British university by unknown hackers and spread rapidly across the Internet.

Is Cataract Surgery Scary?
From Live Science:
This Week’s Question: I have to have cataract surgery and I’m a little frightened. Should I be?
I don’t know anyone who isn’t a little frightened by surgery of any kind, but cataract removal is one of the safest and most effective types of surgery. It’s also one of the most common operations performed in the United States. About 9 out of 10 people who have the surgery have improved vision.
A cataract is a clouding of the lens, the clear part of the eye that helps focus images like the lens in a camera. Cataracts can blur images and discolor them.

From The Telegraph:
Our hopelessly compromised scientific establishment cannot be allowed to get away with the Climategate whitewash, says Christopher Booker.
A week after my colleague James Delingpole, on his Telegraph blog, coined the term "Climategate" to describe the scandal revealed by the leaked emails from the University of East Anglia's Climatic Research Unit, Google was showing that the word now appears across the internet more than nine million times. But in all these acres of electronic coverage, one hugely relevant point about these thousands of documents has largely been missed.

FUTURE HUMANS: Four Ways We May, Or May Not, Evolve
Looking backward, evolutionary theory—popularized by Charles Darwin's On the Origin of Species, published in 1859—has traced humanity's roots to fossil apes. Now, 150 years later, scientists are looking forward and seeing a range of evolutionary futures for humans. Will our descendants be muscle-bound cyborgs? Electronic immortals? Or is human evolution dead? Photograph by Rebecca Hale, NGS
From National Geographic:
But where is evolution taking us? Will our descendants hurtle through space as relatively unchanged as the humans on the starship Enterprise? Will they be muscle-bound cyborgs? Or will they chose to digitize their consciousnesses—becoming electronic immortals?
And as odd as the possibilities may seem, it's worth remembering that, 150 years ago, the ape-to-human scenario in On the Origin of Species struck many as nothing so much as monkey business.
