Astronauts Inspect Discovery Heat Shield -- CBS News

(CBS) The Discovery astronauts conducted an inch-by-inch inspection of the most critical sections of the shuttle's heat shield Saturday, examining the ship's nose cap and wing leading edge panels with a laser scanner on the end of a 50-foot-boom attached to the shuttle's robot arm. 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.

Swine Flu Program Could Be Largest Vaccination Effort In Human History

You Might Feel A Little Pinch

From Popular Science:

With the White House Council of Advisors on Science and Technology estimating that this winter's swine flu outbreak could lead to 30,000 to 90,000 deaths in the US (on top of the usual 30,000 deaths that occur from seasonal flu), the government has ramped up its effort to vaccinate as many Americans as possible against H1N1. In fact, the vaccination effort is so large, it may constitute the largest vaccination program in human history.

From Science Daily:

ScienceDaily (Aug. 29, 2009) — Ice, when heated, is supposed to melt.

That’s why a collection of glaciers in the Southeast Himalayas stymies those who know what they did 9,000 years ago. While most other Central Asian glaciers retreated under hotter summer temperatures, this group of glaciers advanced from one to six kilometers.

A new study by BYU geologist Summer Rupper pieces together the chain of events surrounding the unexpected glacial growth.

Is Quantum Mechanics Selectively Erasing Our Memory?

Entropy At Work: One liquid diffusing into another is an
example of an increase in entropy, or randomness.

From Popular Science:

In a paper published last week, MIT physicist Lorenzo Maccone hypothesizes that, yes, quantum physics is messing with our minds. The laws of physics work just as well if time is running forwards or backwards. But we all seem to experience time running in only one direction, and in the same direction as everyone else -- a mystery of physics that's yet to be solved.

Man-Made Volcanoes May Cool Earth

The Anak Krakatau volcano

From Times Online:

THE Royal Society is backing research into simulated volcanic eruptions, spraying millions of tons of dust into the air, in an attempt to stave off climate change.

The society will this week call for a global programme of studies into geo-engineering — the manipulation of the Earth’s climate to counteract global warming — as the world struggles to cut greenhouse gas emissions.

It will suggest in a report that pouring sulphur-based particles into the upper atmosphere could be one of the few options available to humanity to keep the world cool.

Stevenage: The Final Frontier In Space Technology

The rocket and fuel tanks of the Lisa Pathfinder satellite, which will be launched in 2011 and pave the way for new scientific experiments on gravitational wave detection and black holes.

From The Daily Mail:

You might think Nasa is the only pioneer of space technology, but this £200m satellite (below) is being built not in Houston but at a sleepy industrial estate in Hertfordshire.

It's so tantalisingly close, this strange octagonal aluminium box with its shimmery array of circuitry. I see wires coated in silver, connectors of gold, and parts so delicate that even in this temperature-and humidity-controlled, dust-free environment they have to be protected with pink translucent plastic bags.

In two years' time, this box - the inside of a satellite - will be blasted four times further out into space than any human has ever been.

From Science Daily:

ScienceDaily (Aug. 28, 2009) — University of Utah researchers used data from Portuguese water dogs – the breed of President Barack Obama's dog Bo – to help find a gene that gives some dogs curly hair and others long, wavy hair.

It was part of a National Institutes of Health (NIH) study – published online Thursday, Aug. 27 by the journal Science – showing that variations in only three genes account for the seven major types of coat seen in purebred dogs. The findings also point the way toward understanding complex human diseases caused by multiple genes.

From Time Magazine:

Like more than a billion fellow Muslims around the world, Sulley Muntari began the monthlong fasting ritual of Ramadan on Aug. 22. Abstaining from food or drink during daylight hours is challenging enough for the average person, but for the Ghana-born Muntari, a professional soccer player with Italy's Serie A team Inter Milan, running more than six miles per game on an empty stomach might have proved to be too much. In his first match after the start of Ramadan, the midfielder was removed from the game after just half an hour of play.

From Technology Review:

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

In recent years, the Austrian physicist Anton Zeilinger has bounced entangled photons off orbiting satellites and made 60-atom fullerene molecules exist in quantum superposition--essentially, as a smear of all their possible positions and energy states across local space-time. 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.

Crazy English: How China's Language Teachers Became Big Celebrities -- The Independent

This year it will be announced that China now has more English speakers than any other country in the world. And such is the demand for their services that top teachers have become big stars.

"Where are you from? Do you speak English?" It's a familiar phrase near the Forbidden City in Beijing, or along the capital's Nanjing Road, as Chinese people try a standard opening gambit to spark up a conversation with a foreigner. Many visitors baulk at being approached so baldly, and are worried that it could be a scam. Very occasionally it is a con – and tourists should be wary when some nice young people offer to bring them to a tea house – but mostly the youngsters are desperate for access to real live Anglophones who can help them improve their conversational English.

New Theory For Why We Cry

Do we cry because it makes us feel good, or because it cleanses us of stressful chemicals? Or, as Oren Hasson now theorizes, is a good cry just a way to get attention and gain acceptance? Image credit: stockxpert

From Live Science:

We shed tears when in pain, but what purpose does crying have?

A scientist now proposes a new theory for why crying evolved — tears can act as handicaps to show you have lowered your defenses.

"Crying is a highly evolved behavior," said researcher Oren Hasson, an evolutionary biologist at Tel Aviv University in Israel. "My analysis suggests that by blurring vision, tears lower defenses and reliably function as signals of submission, a cry for help, and even in a mutual display of attachment and as a group display of cohesion."

Watermelon Juice - Next Source of Renewable Energy


From Reuters:

Hundreds of thousands of tons of watermelons are tossed every year because they aren't good enough for market. A new study finds that the juice from these watermelons could easily be used to create the biofuel ethanol and other helpful products.

According to a new study to be published in the journal Biotechnology for Biofuels, 20% of the watermelon crop doesn't go to market every year due to imperfections, bad spots, or weird shapes. These watermelons are left in the field and then ploughed right back into the ground. According to the authors of the study (Benny Bruton and Vincent Russo from the USDA-ARS, South Central Agricultural Research Laboratory, and Wayne Fish), these watermelons could be used to produce the biofuel ethanol.
