stanley kubek fter a coal mine explosion in West Virginia. This has been an unimaginably difficult week for the people who live near Montcoal, said Mr. Obama.Obama said Friday more needs to be done to ensure mine safety. He has asked federal officials to report to him next week on the cause of Monday s deadly explosion. Officials have suggested a buildup of methane might have been to blame.The blast killed at least 25 miners. Toxic gases have hampered attempts to search for the missing miners. Rescue teams trekked far enough into a ruined coal mine early Friday to see that no one had used

It was the latest gut-wrenching setback in a rescue effort that started with only the slimmest likelihood of finding anyone alive after Monday s blast, the worst U.S. mine disaster in two decades.It was the third time since the explosion at Massey Energy Co. s Upper Big Branch mine that rescuers had to pull back after making their way about 1,000 feet below the surface and about five miles into the massive coal mine. The teams had to scramble back to the surface during their previous attempts becaus Raug Mega Millions: 2 winning tickets sold; jackpot may hit $648M
Not content with perhaps the biggest scientific discovery of the decade, scientists at the Large Hadron Collide continue to search for new particles鈥攁nd now they ;ve found one that seems to be an entirely new form of matter.

Its sighting at the LHC changes things. Researchers from CERN have found as many as 4000 of the particles, which means that those who think tetraquarks do exist are pretty excited. There remains some work to be done to understand once and for all if Z 4430 is with 100 percent certainty a tetraquark, and even then exactly what that means for us. But in the meantime, it nice to know th
