Many institutions have their archives stored on CDs — but the discs aren't as stable as once thought. There is no average life span for a CD, says preservationist Michele Youket, "because there is no average disc." --- Back in the 1990s, historical societies, museums and symphonies across the country began transferring all kinds of information onto what was thought to be a very durable medium: the compact disc. Now, preservationists are worried that a lot of key information stored on CDs — from sound recordings to public records — is going to disappear. Some of those little silver discs...

RoboBrain marks the dawn of cloud robotics Posted by: Emily Smith August 25, 2014 in Tech RoboBrain is the new attempt of artificial intelligence researchers to create a cloud-based database that would help out existing and future robots. In theory, RoboBrain is supposed to be a massive database of all the information robots have been taught so far and offers the possibility of increasing that knowledge as well. The main idea behind RoboBrain is that the cumulative knowledge robots have been able to gather should be collected in the same place, namely cloud storage, and made available to every robot...

Pierre Sprey is one of the original designers of the A-10 Warthog during the 1970s. He provides insight into why the aircraft is so loved by ground troops in the military, and why its recent retirement from Air Force operations is so hotly debated.

The ‘Top 5’ landing site candidates have been chosen for the Rosetta orbiters piggybacked Philae lander for humankind’s first attempt to land on a comet. See graphics above and below. The potential touchdown sites were announce today, Aug. 25, based on high resolution measurements collected by ESA’s Rosetta spacecraft over the past two weeks since arriving at the bizarre and pockmarked Comet 67P/Churyumov-Gerasimenko on Aug. 6, 2014. ... Their goal was to find a ‘technically feasible’ touchdown site that was both safe and scientifically interesting. “The site must balance the technical needs of the orbiter and lander during all phases...

The Army’s test of an advanced hypersonic weapon failed shortly after takeoff early Monday, the Pentagon said in a statement. The failure is a setback for a key part of the Pentagon’s strategic weapon program of building arms that can attack any point on earth in 30 minutes. The missile carrying the weapon was intentionally blown up shortly after launch, the Pentagon said. “Due to an anomaly, the test was terminated near the launch pad shortly after liftoff to ensure public safety,” the Pentagon said in a brief statement. “There were no injuries to any personnel.” “Program officials are conducting...

A difficult math question. One would hope that these two did not finish high school. If they did, public education needs to refund our money. https://www.facebook.com/photo.php?v=10202517290999274

Explanation: Why does this galaxy have such a long tail? In this stunning vista, based on image data from the Hubble Legacy Archive, distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. The cosmic tadpole is a mere 420 million light-years distant toward the northern constellation Draco. Its eye-catching tail is about 280 thousand light-years long and features massive, bright blue star clusters. One story goes that a more compact intruder galaxy crossed in front of Arp 188 - from right to left in this view - and was slung around behind the Tadpole...

After serving nearly 30 years as a doorstop for a nuclear physicist, a hunk of petrified wood from Arizona has finally been recognized as a one-of-a-kind find. The 210-million-year-old piece of wood contains the first fossilized fire scar ever discovered... Evidence for ancient forest fires predates the dinosaurs, but the clues come from charcoal, not from marks on fossilized trees. Charcoal remains of Earth's oldest fires date back more than 400 million years. No one has ever spotted a fire scar on petrified wood before, said lead study author Bruce Byers, a natural resources consultant from Falls Church, Virginia. That's...

Congratulations to The Australian again for taking the hard road and reporting controversial, hot, documented problems, that few in the Australian media dare to investigate. How accurate are our national climate datasets when some adjustments turn entire long stable records from cooling trends to warming ones (or visa versa)? Do the headlines of “hottest ever record” (reported to a tenth of a degree) mean much if thermometer data sometimes needs to be dramatically changed 60 years after being recorded?One of the most extreme examples is a thermometer station in Amberley, Queensland where a cooling trend in minima of 1C per...

Explanation: What's that dot on the Sun? If you look closely, it is almost perfectly round. The dot is the result of an unusual type of solar eclipse that occurred in 2006. Usually it is the Earth's Moon that eclipses the Sun. This time, the planet Mercury took a turn. Like the approach to New Moon before a solar eclipse, the phase of Mercury became a continually thinner crescent as the planet progressed toward an alignment with the Sun. Eventually the phase of Mercury dropped to zero and the dark spot of Mercury crossed our parent star. The situation could...

Bone chemistry sheds light on the monarch's shifting diet throughout his brief life Richard III was only 32 years old when he was struck down at the Battle of Bosworth Field in 1485. But according to new research, the King of England at least enjoyed some good eating throughout his life—especially in the few years leading up to his death. Scientists from the British Geological Survey and the University of Leicester analyzed Richard III's teeth, his femur and his ribs to see what they could reveal about the monarch's diet, Phys.org reports. They used isotope analysis to identify chemical signatures...

Explanation: The city of Veszprem, Hungary was only briefly haunted by this mysterious spectre. On the morning of August 11, its monstrous form hovered in the mist above municipal buildings near the town center. A clue to its true identity is offered by the photographer, though, who reports he took the picture from the top of a twenty story building with the rising Sun directly at his back. That special geometry suggests this is an example of an atmospheric phenomenon called the Glory or sometimes "the Spectre of the Brocken". Also seen from mountain tops and airplanes when looking opposite...

Explanation: On July 13th, a good place to watch Comet Jacques was from Venus. Then, the recently discovered visitor (C/2014 E2) to the inner solar system passed within about 14.5 million kilometers of our sister planet. But the outbound comet will pass only 84 million kilometers from our fair planet on August 28 and is already a fine target for telescopes and binoculars. Two days ago Jacques' greenish coma and straight and narrow ion tail were captured in this telescopic snapshot, a single 2 minute long exposure with a modified digital camera. The comet is flanked by IC 1805 and...

Explanation: On Monday morning, Venus and Jupiter gathered close in dawn skies, for some separated by about half the width of a full moon. It was their closest conjunction since 2000, captured here above the eastern horizon before sunrise. The serene and colorful view is from Istia beach near the city of Capoliveri on the island of Elba. Distant lights and rolling hills are along Italy's Tuscan coast. Of course, the celestial pair soon wandered apart. Brighter Venus headed lower, toward the eastern horizon and the glare of the Sun, while Jupiter continues to rise a little higher now in...

Explanation: The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. The tremendously bright nearby star, Herschel 36, lights the area. Walls of dust hide and redden other hot young stars. As energy from these stars pours into the cool dust and gas, large temperature differences in adjoining regions can be created generating shearing winds which may cause the funnels. This picture, spanning about 5 light years, combines images...

Explanation: Where should Philae land? As ESA's robotic spacecraft Rosetta circles toward Comet 67P/ Churyumov-Gerasimenko, a decision must eventually be made as to where its mechanical lander should attempt to touch-down. Reaching the comet earlier this month, Rosetta is sending back detailed pictures of the comet's unusual nucleus from which a smooth landing site will be selected. Pictured above, near the image top, the head of the comet's nucleus shows rugged grooves, while near the image bottom, the body shows a patch-work of areas sometimes separated by jagged hills. Some of the patch-work areas apparent on both the head and...

On a clear July day in 1966, New York Central Railroad engineer Don Wetzel and his team boarded a specially modified Buddliner railcar. Bolted to the roof above them were two GE J47-19 jet engines. Wetzel throttled the engines up and tore down a length of track from Butler, Indiana, to Stryker, Ohio, at almost 184 mph, piloting the experimental vehicle into the record books as the world’s fastest jet-powered train.

Two years of research by a Nigerian scientist has shown that sufferers of Alzheimer's and Parkinson's disease could be helped by punicalagin, a compound extracted from pomegranates. Olumayokun Olajide from the University of Huddersfield in West Yorkshire showed how punicalagin could inhibit inflammation in specialised brain cells known as micrologia. He also found the painful inflammation that accompanies illnesses such as rheumatoid arthritis and Parkinson's disease could be reduced using the same drug. "We do know that regular consumption of pomegranate has a lot of health benefits, including prevention of neuro-inflammation related to dementia," Olajide added.

A copper awl is the oldest metal object unearthed to date in the Middle East. The discovery reveals that metals were exchanged across hundreds of miles in this region more than 6,000 years ago, centuries earlier than previously thought, researchers say.

NASA is planning to send rats to the International Space Station (ISS) for a longer duration of up to three months to better understand the long-term effects of micro-gravity on living organisms. While rodents have flown on space shuttle flights in the past, those missions have only lasted a week or two. The new mission, however, could range between 30 and 90 days, depending on the availability of spacecraft to ferry them on the round-trip, ‘Space.com’ reported. “This will allow animals to be studied for longer period of time on space station missions,” said Julie Robinson, NASA’s chief scientist for...
