Want to see a collision between the cores of two merging galaxies, each powered by a black hole with a  millions of times the mass of the sun?You're in luck.   NASA's Spitzer Space Telescope recently caught that very thing.   The galactic cores are in a single, tangled galaxy called NGC 6240, located 400-million light years away in the constellation Ophiuchus. Millions of years ago, each core was the dense center of its own galaxy before the two galaxies collided and ripped each other apart. Now, these cores are approaching each other at tremendous speeds and preparing for the final cataclysmic collision. They will crash into each other in a few million years, a relatively short period on a galactic timescale.

Sixty-one teams from Southern California, Arizona, Brazil and Chile faced off in the Los Angeles regional FIRST Robotics Competition on March 13 and 14. JPL sponsored nine of the schools in this annual engineering and technology contest held at the Long Beach Convention Center. The teams from Centinela Valley Union High School District, Lawndale; Atascadero High School, Atascadero; and the NASA-sponsored Bishop Alemany High School, Mission Hills, won the regional competition and will compete in the FIRST championship competition in Atlanta, from April 16-19. Chaminade College Preparatory, in West Hills, won the competition's highest award, the Regional Chairman's Award, and will also go to Atlanta. 

A herd of young birdlike dinosaurs met their death on the muddy margins of a lake some 90 million years ago, according to a team of Chinese and American paleontologists that excavated a site in the Gobi Desert in western Inner Mongolia.  The sudden death of the herd in a mud trap provides a rare snapshot of social behavior. Composed entirely of juveniles of a single species of ornithomimid dinosaur (Sinornithomimus dongi), the herd suggests that immature individuals were left to fend for themselves when adults were preoccupied with nesting or brooding.

Sometimes different is good.  You may not want a strange cup of coffee when you go to Starbucks and you would like for your car to work the way cars should, but in science the peculiar can teach us a lot. This was the idea behind Halton Arp’s catalogue of Peculiar Galaxies that appeared in the 1960s. One of the oddballs listed there is Arp 261, which has now been imaged in more detail than ever before using the FORS2 instrument on ESO’s Very Large Telescope.

Massive predators like Albertosaurus and Tyrannosaurus rex may have been at the top of the food chain, but they were not the only meat-eating dinosaurs to roam North America, according to Canadian researchers who have discovered the smallest dinosaur species on the continent to date. Their work is also helping re-draw the picture of North America's ecosystem at the height of the dinosaur age 75 million years ago.

Czar Nicholas II, eldest son of Tsar Alexander III, succeeded hs father in 1894 and, while he wasn't the most incompetent leader in the history of Russia, much less all of Europe, he was without question a disaster, losing a war to Japan and ordering the army to shoot at citizens who protested the poor conditions they lived under.  It's no surprise anyone wanted him gone.    A crazy shrew of a wife under the spell of Rasputin didn't help his decision-making prowess. 

That guy who gets in the elevator reeking of Drakkar Noir is nothing new - the Ancient Egyptians cherished their fragrant scents, too.   In a new part of its permanent exhibition, Bonn University's Egyptian Museum has on display a particularly well preserved example of that.Screening this 3,500-year-old flacon with a computer tomograph, scientists at the university detected the desiccated residues of a fluid, which they now want to submit to further analysis. They might even succeed in reconstructing this scent.

In the early parts of the decade, German and British intelligence said that Iraq had acquired weapons of mass destruction and were on their way to nuclear capability.    The American CIA agreed.    Saddam Hussein, in maybe the stupidest bluff of this century (there's still a long way to go), refused to let UN inspectors investigate thoroughly, perhaps thinking if the world believed he had nuclear capability, they would lift sanctions.    His mistakes cost him a wealthy dictatorship (though gold painted fixtures remain a puzzle to anyone who visits his many palaces) and, eventually, his life.

Sharks are among the most popular animals featured in television and cinema. And today among sharks, the undisputed king is the great white, a giant predator that can exceed 20 feet in length. Despite the popularity of great whites, relatively little is known about their biology, and even less is known about their evolutionary origins. A new 4-million-year-old fossil from Peru described in the Journal of Vertebrate Paleontology provides important evidence suggesting the shark’s origins may be more humble than previously believed.

If the Higgs boson, whatever that will turn out to be, is hiding, wherever it may be found continues to shrink. The latest analysis of data from the CDF and DZero collider experiments at Fermilab has now excluded a significant fraction of the allowed Higgs mass range established by earlier measurements. Those experiments predict that the Higgs particle should have a mass between 114 and 185 GeV/c2. Now the CDF and DZero results carve out a section in the middle of this range and establish that it cannot have a mass in between 160 and 170 GeV/c2.

It seems obvious; even in a noble profession like education, if you pay people more who are better at it, better people are incentivized to do it. Obviously a number of people do it despite the money, just like science and academia, and the overall quality of education has improved a lot this decade but America has a way to go if we are going to keep at the forefront of science and technology in the face of huge populations in China and India.
But there has been resistance to that from educational lobbyists and a hardline union that only votes Democrat, which has unfortunately made education a political football.

Nyiragongo, an active African volcano, possesses lava unlike any other in the world, which may point toward its source being a new mantle plume says a University of Rochester geochemist. The lava composition indicates that a mantle plume—an upwelling of intense heat from near the core of the Earth—may be bubbling to life beneath the soil of the Democratic Republic of the Congo. The findings are presented in the current issue of the journal Chemical Geology.
