From CBS News:

KENNEDY SPACE CENTER, Fla. - After a close-up, focused inspection of a damaged heat shield tile on the belly of space shuttle Endeavour, NASA analysts have concluded that there is no threat posed to the orbiter, and NASA's Mission Management Team cleared the ship for re-entry as-is.

"So all good results all the way around," said MMT Chairman LeRoy Cain. "We're essentially clearing the vehicle for re-entry at this point. There were no dissenting opinions, no alternate opinions; the entire team was pretty much on board with the assessments that were done."

Free-Floating "Planets" Are More Common Than What Is Believed

The "rogue" planets act as lenses, bending the light from distant stars

'Free-Floating' Planets Found With No Star In Sight -- BBC

An international team of astronomers claim to have found free-floating "planets" which do not seem to orbit a star.

Writing in Nature, they say they have found 10 Jupiter-sized objects which they could not connect to any solar system. They also believe such objects could be as common as stars are throughout the Milky Way.

The objects revealed themselves by bending the light of more distant stars, an effect called "gravitational microlensing".

Radio Telescopes Capture Best-Ever Snapshot of Black Hole Jets

From Science Daily:

ScienceDaily (May 20, 2011) — An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.

"These jets arise as infalling matter approaches the black hole, but we don't yet know the details of how they form and maintain themselves," said Cornelia Mueller, the study's lead author and a doctoral student at the University of Erlangen-Nuremberg in Germany.

How To Manipulate Social Movements By Hacking Twitter

Are You Following A Bot? -- The Atlantic

How to manipulate social movements by hacking Twitter.

One day last February, a Twitter user in California named Billy received a tweet from @JamesMTitus, identified in his profile as a “24 year old dude” from Christchurch, New Zealand, who had the avatar of a tabby cat. “If you could bring one character to life from your favorite book, who would it be?,” @JamesMTitus asked. Billy tweeted back, “Jesus,” to which @JamesMTitus replied: “honestly? no fracking way. ahahahhaa.” Their exchange continued, and Billy began following @JamesMTitus. It probably never occurred to him that the Kiwi dude with an apparent love of cats was, in fact, a robot.

Massive Storm Erupts On Saturn -- Cosmos

MARYLAND: A giant early-spring storm in Saturn's northern hemisphere - so powerful that it stretches around the entire planet - has been detected.

The rare storm has been wreaking havoc for months and shooting plumes of gas high into the planet's atmosphere, according to data from NASA's Cassini spacecraft and a European Southern Observatory ground-based telescope, that have been tracking its progress

'Dark Energy' Confirmed

New Method 'Confirms Dark Energy' -- BBC

First results from a major astronomical survey using a cutting-edge technique appear to have confirmed the existence of mysterious dark energy.

Dark energy makes up some 74% of the Universe and its existence would explain why the Universe appears to be expanding at an accelerating rate.

The finding was based on studies of more than 200,000 galaxies.

How Piano Wires Changed Through The Centuries

How Piano Wires Changed Through Centuries -- Discovery

Since Mozart's time, piano wires have changed in content -- but very little in quality, research shows.

* The wire inside pianos has undergone significant changes between the piano's origins in the early 1700s until the late 1880s.
* Research suggests that piano designers used music wire to reach similar harmonic levels despite working with different metals.
* Piano designers balance tension and stiffness of music wire, but many other factors are considered as well.

Atmosphere Above Epicentre Of Deadly Japan Earthquake Heated Up 'Rapidly' In Days Before Disaster

Satellite images showing changes in the heat of the atmosphere above the epicentre of the March 11 earthquake between March 1 and March 12. The total electron content in the ionosphere increased dramatically before the quake

A Warning Sign? Atmosphere Above Epicentre Of Deadly Japan Earthquake Heated Up 'Rapidly' In Days Before Disaster -- The Daily Mail

* Scientists hope they will one day be able to predict quakes uses air ionisation data.

The atmosphere directly above the fault zone which produced Japan's recent devastating earthquake heated up significantly in the days before the disaster, a study has shown.

Before the March 11 earthquake, the total electron content in a part of the upper atmosphere, called the ionosphere, increased dramatically over the earthquake's epicentre, reaching a maximum three days before the quake struck.

It is believed that in the days before an earthquake, the stresses on geological faults in the Earth's crust causes the release of large amounts of radon gas.

U.S. Special Ops Building Satellites To Track Terrorists Everywhere -- Popular Mechanics

The raid on Osama bin Laden's compound this month highlighted special forces' focus on finding high-value targets. Their hunt extends into space, too. An official with U.S. Special Operations Command has confirmed that his organization is testing tiny satellites that could keep tabs on targets from above.

An official with Special Ops revealed Wednesday that the U.S. recently launched mini-satellites that could clandestinely track high-value targets, like al-Qaida terrorists. "We sent up four satellites to demonstrate passing TTL [tagging, tracking, locating] data," Doug Richardson, a civilian official at U.S. Special Operations Command, told an audience on Wednesday, referring to a December launch of a SpaceX rocket carrying the CubeSats—inexpensive satellites so small they can fit in the palm of your hand, and which have been used for scientific missions for a number of years.

Robots Learning Their Own Language

Robots Learn To CreateTheir Own Spoken Language -- Popular Science

Having a computer for a brain has its perks, but it has its drawbacks as well. Language is a tough concept for robots, as words can convey the abstract as well as the concrete and robots have trouble knowing the difference (and grasping the abstract). That makes human-machine interaction less than intuitive for humans and confusing to ‘bots. But Australian researchers are hoping to change that by teaching robots to communicate verbally in a language of their own creation, the same way humans did.

If the undead really start roaming the earth looking for fresh brains to eat, we can't rely on our ability to shoot 'em dead the way people do in video games or in horror flicks. Instead, the agency says, we need to treat it like any other disaster.

Planets More Numerous Than Believed

Planets May Be Vastly More Numerous Than Believed -- L.A. Times

Researchers say that millions of Jupiter-sized planets are wandering in our galaxy far from any star. The findings suggest that there may be twice as many planets as stars in the Milky Way, perhaps several times as many.

The Milky Way galaxy may be filled with millions upon millions of Jupiter-sized planets that have escaped their solar systems and are wandering freely in space, researchers said Wednesday in a finding that seems certain to make astronomers rethink their ideas about planetary formation.

Scientists had previously thought that about 20% of stars had massive planets attached to them, but the new results reported in the journal Nature suggest that there are at least twice as many planets as stars, and perhaps several times as many.

It was an era that defined a generation. The Great Depression marked the bitter and abrupt end to the post-World War 1 bubble that left America giddy with promise in the 1920s. Near the end of the 1930s the country was beginning to recover from the crash, but many in small towns and rural areas were still poverty-stricken. These rare photographs are some of the few documenting those iconic years in colour. The photographs and captihttp://www.blogger.com/img/blank.gifons are the property of the Library of Congress and were included in a 2006 exhibit Bound for Glory: America in Color.
