Cosmic Explosion Is New Candidate For Most Distant Object In The Universe -- Science Daily

ScienceDaily (May 25, 2011) — A gamma-ray burst detected by NASA's Swift satellite in April 2009 has been newly unveiled as a candidate for the most distant object in the universe. At an estimated distance of 13.14 billion light years, the burst lies far beyond any known quasar and could be more distant than any previously known galaxy or gamma-ray burst. Multiple lines of evidence in favor of a record-breaking distance for this burst, known as GRB 090429B for the 29 April 2009 date when it was discovered, are presented in a paper by an international team of astronomers led by former Penn State University graduate student Antonino Cucchiara, now at the University of California, Berkeley.

Did The Military Cause The Tornadoes That Devastated Joplin, Mo.?

Tornadoes Caused by Military?: Recent Events Fuel Conspiracy Theories -- ABC News

It's an astonishing claim: The tornado that ravaged Joplin, Mo., last Sunday, killing at least 125 people, was not a random act of nature but the result of an obscure military-backed research program in Alaska that shoots radio waves into the upper atmosphere.

Here's another one: The shooting rampage in Tucson last January that killed six people and wounded 13, including Rep. Gabrielle Giffords, was an elaborate government hoax that used actors to portray the victims.

Scientists Detect Earth-Equivalent Amount of Water Within the Moon -- Science Daily

ScienceDaily (May 26, 2011) — There is water inside the moon -- so much, in fact, that in some places it rivals the amount of water found within Earth.

The finding from a scientific team including Brown University comes from the first-ever measurements of water in lunar melt inclusions. Those measurements show that some parts of the lunar mantle have as much water as Earth's upper mantle.

Babies Are Capable of Complex Reasoning -- Live Science

Babies are sophisticated mini-statisticians, a new study finds, capable of making judgments about the probability of an event they've never seen before.

Using a computer model, researchers were able to accurately predict what a baby would know about a particular event if given certain information. The model may be useful in engineering artificial intelligence that reacts appropriately to the world, said study researcher Josh Tenenbaum, a cognitive scientist at the Massachusetts Institute of Technology. The study also demonstrates just how savvy baby brains are, Tenenbaum told LiveScience.

Many wall-walking robots mimic natural adhesives--like the sticky feet of geckos--to remain fixed to a surface while they scale it.

But this little bot uses nothing but a supersonic version of a well-known principle of fluid dynamics to cling to just about any surface--without the surface of its grippers ever actually touching it.

U.S. Congress Getting Ready To Tax The Internet

How Will States Tax Internet Downloads? Congress May Decide -- Epicenter

Here’s an interesting conundrum, posed by Representative Dennis Ross (R-Florida), at a House Judiciary subcommittee hearing held on Monday:

“Imagine you are sitting in Dulles airport in Virginia, waiting for a flight back to Florida,” Ross began in his opening remarks. “You download a music file from Apple, which is headquartered in California. The music is sent to you via a server in Oklahoma.”

Which of these states should be allowed to tax the sale?

Without a “clear national rule,” he warned at the hearing, “all four states may attempt to tax the transaction.”

My Comment: Another tax grab .... get ready for it.

NASA's Mars Rover Spirit To Be Shut Down

NASA's Mars rover Spirit, shown in an artist's rendering, was expected to serve a three-month mission, but it provided scientists with a trove of information over more than six years of operation. (Reuters)

NASA Rover Spirit 'Revolutionized' How We See Mars -- L.A. Times

As the Martian rover falls silent for good, JPL scientists mourn Spirit's loss and celebrate its remarkable achievements that continued for years beyond its expected lifetime.

It was supposed to roam the surface of Mars for only three months and cover a distance of just a few hundred yards. Instead, NASA's Spirit rover traveled nearly five miles over five years, finding geological evidence that the Red Planet had once been warm and wet enough to have harbored life. Even after it got hopelessly stuck in the powdery soil of Gusev crater, the rover continued to make discoveries and beamed them to scientists millions of miles away.

Smallpox-Destruction Deadline Delayed For 3 Years -- Wall Street Journal

Global health officials delayed setting a deadline Tuesday for destroying the last known stocks of smallpox for at least three years, a compromise that will enable the U.S. and Russia to continue researching medications to counter a bioterror attack.

The consensus at the World Health Assembly, the decision-making body of the World Health Organization, came after a contentious debate stretching over two days. It represents a compromise for the U.S., Russia and more than two dozen other countries that wanted to keep the virus stocks for at least another five years. Iran, China, Thailand and other countries objected to that timetable and some of its provisions.

It Seems That Man Has Been At War With His Fellow Man For A Very Long Time

Bronze Age relic: Archaeologists have found the remains of around 100 bodies in the Tollense Valley in northern Germany, including this fractured skull

'Earliest' Bronze Age Battle Site Containing 100 Bodies Found On German River Bank -- The Daily Mail

Fractured skulls and broken bones found on a German river bank could point to the earliest site of a Bronze Age battle ever discovered.

Archaeologists uncovered the remains of around 100 bodies in the Tollense Valley in northern Germany, suggesting brutal hand-to-hand combat between warring tribes.

Bones had been battered, skulls were fractured and one body has an arrowhead buried more than 2cm inside it.

Surprise Find In Kepler Planet Hunt: Lots Of Multi-Planet Systems -- Christian Science Monitor

NASA's Kepler spacecraft, which is searching for Earth-mass planets orbiting sun-like stars, is finding hundreds of candidate planets, and many more multi-planet systems than expected.

Two years into a 3-1/2-year mission, NASA’s Kepler spacecraft, hunting for planets orbiting some 165,000 stars in the constellation Cygnus, is uncovering planet candidates by the hundreds.

Many of these inhabit multi-planet systems that are unexpectedly flat – the inclination of the planets’ orbits within each of these systems are essentially the same, a feature that may hold clues about how these systems formed and evolved.

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".

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.
