The moon has a new hole on its surface thanks to a boulder that slammed into it in March, creating the biggest explosion scientists have seen on the moon since they started monitoring it.

The meteorite crashed on March 17, slamming into the lunar surface at a mind-boggling 56,000 mph (90,000 kph) and creating a new crater 65 feet wide (20 meters). The crash sparked a bright flash of light that would have been visible to anyone looking at the moon at the time with the naked eye, NASA scientists say.

“On March 17, 2013, an object about the size of a small boulder hit the lunar surface in Mare Imbrium,” Bill Cooke of NASA’s Meteoroid Environment Office said in a statement. “It exploded in a flash nearly 10 times as bright as anything we’ve ever seen before.” [The Greatest Lunar Crashes Ever]

Asteroid 1998 QE2 To Give Earth A Close Shave On May 31 (VIDEO)

FROM

.

A gigantic asteroid will fly by our planet at the end of this month, making its closest approach for at least the next two centuries on May 31. But, don’t worry, it won’t get closer than about 3.6 million miles, which is around 15 times the distance between Earth and the moon.

Astronomers plan to use radar telescopes to get a good look at the space rock, named Asteroid 1998 QE2, between May 30 and June 9.

“Asteroid 1998 QE2 will be an outstanding radar imaging target at Goldstone and Arecibo [observatories] and we expect to obtain a series of high-resolution images that could reveal a wealth of surface features,” radar astronomer Lance Benner, the principal investigator for the Goldstone radar observations from NASA’s Jet Propulsion Laboratory, said in a written statement.

Willie Wilkins, Veteran, Gets Back Dog Tag He Lost In World War II

Carol Wilkins leaned over the side of her father’s wheelchair and handed him the small red box, a heart-shaped cutout revealing its contents: a weathered, bent silver dog tag.

“Oh, Daddy, look,” Wilkins exclaimed as her 90-year-old father opened it, his eyes beaming and smile wide. “They’re back.”

Sixty-nine years after losing his dog tag on the battlefields of southern France, Willie Wilkins reclaimed it Wednesday after a trans-Atlantic effort to return it to him. It started more than a decade ago in a French backyard and ended with a surprise ceremony in Newark City Hall.

“I am so happy,” Carol Wilkins said. “You don’t know what joy is on my heart for what you have done for my father.”

Antimatter-Gravity ‘Alpha’ Experiment At CERN Tests Force’s Effect, Yields Ambiguous Result

FROM

.

When it comes to antimatter, what goes up doesn’t necessarily come down. In a new study, physicists weighed antimatter in an effort to determine how this strange cousin of matter interacts with gravity.

Ordinary matter atoms fall down due to the pull of gravity, but the same might not be true of antimatter, which has the same mass as matter, but opposite charge and spin. Scientists wondered whether antimatter atoms would instead fall up when pulled by gravity, and whether such a thing as antigravity exists.

“In the unlikely event that antimatter falls upward, we’d have to fundamentally revise our view of physics and rethink how the universe works,” Joel Fajans, a physicist at the Lawrence Berkeley National Laboratory in California, said in a statement.

Fajans and his colleagues at the Alpha experiment at Switzerland’s CERN physics lab made the first experimental measurements of the gravitational mass of antihydrogen — the antimatter equivalent of hydrogen, made of an antiproton and a positron (the antimatter counterpart to an electron).

Too-Big-To-Fail Banks Have Raked In $102 Billion In Subsidies Since 2009: Report

FROM

.

America’s biggest banks want you to believe that they get no special advantage, no subsidies, from being too big to fail. And yet people keep finding evidence of those subsidies.

The latest is World Bank economist Deniz Anginer, in a study for Bloomberg Markets magazine. Anginer estimates that the six biggest U.S. banks have saved $82 billion in borrowing costs since 2009 because investors believe the government will never let them fail and thus don’t charge as much to lend them money as they do smaller banks. The report will be published in the June issue of the magazine.

Together with dirt-cheap government borrowing programs, Bloomberg estimates these banks — JPMorgan Chase, Bank of America, Citigroup, Wells Fargo, Goldman Sachs and Morgan Stanley — have saved $102 billion since 2009 because of their size advantage.

New discovery may be step toward ending malaria

Click link below picture

.

Worldwide elimination of malaria would save hundreds of thousands of lives each year, according to the World Health Organization (WHO). But eradication remains elusive, because the parasite that causes the disease can evolve to withstand the effects of new malaria drugs and become drug-resistant.

Researchers, however, now believe they have discovered a way to track the spread of drug-resistant malaria, and this discovery may help to finally eradicate the disease. Their study was recently published in the journal Nature Genetics.

“We’ve seen past cases of (malaria) drug resistance spread in a specific pattern,” said study author Nicholas White from Mahidol University in Bangkok, Thailand, and the University of Oxford in the UK. “It starts in Cambodia, spreads across Southeast Asia and crosses over to Africa, killing millions of children in the process.”

DR Congo toughest place for mothers – Save the Children

.

The Democratic Republic of Congo is the world’s toughest place to raise children, Save the Children reports.

Finland was named the best place to be a mother, with Sweden and Norway following in second and third places.

The charity compared factors such as maternal health, child mortality, education and income in 176 countries.

In India, over 300,000 babies die within 24 hours of being born, accounting for 29% of all newborn deaths worldwide, the report says.

The 10 bottom-ranked countries were all from sub-Saharan Africa, with one woman in 30 dying from pregnancy-related causes on average and one child in seven dying before his or her fifth birthday.

In DR Congo, war and poverty have left mothers malnourished and unsupported at the most vulnerable time of their lives.

Gravity Waves, Predicted By Einstein’s General Relativity Theory, May Soon Be Detected

FROM

.

In the next five years or so, scientists are poised to discover proof that space and time can wrinkle in the form of gravitational waves. These waves were predicted almost 100 years ago by Albert Einstein’s general theory of relativity, but have yet to be seen.

That could change soon when the latest, most sensitive experiments hunting gravitational waves come online. “There’s so much activity and excitement in the field right now,” said Mansi M. Kasliwal, an astronomer at the Observatories of the Carnegie Institution for Science in Pasadena, Calif. “The momentum is really building.”

Kasliwal is the author of a paper published online today (May 2) in the journal Science describing the burgeoning field of gravitational wave studies.

Willie Jerome Manning Execution Blocked By Mississippi Supreme Court

FROM

Click link below picture

.

The Mississippi Supreme Court has indefinitely delayed Tuesday’s scheduled execution of Willie Jerome Manning amid questions involving evidence in the case, intervening hours before he was set to die for the slayings of two college students.

Manning, who had challenged errors involving evidence analysis, was originally set to receive a lethal injection at 6 p.m. CDT at the state prison in Parchman. But with mere hours remaining, the high court blocked the execution until it rules further in the case.

Manning was convicted in 1994 in the shooting deaths of two Mississippi State University students, Jon Steckler and Tiffany Miller. Their bodies were found in a rural area in December 1992.

The FBI has said in recent days that there were errors in agents’ testimony about ballistics tests and hair analysis in the case.

The Cicadas Are Coming: Billions Of Insects To Emerge After 17 Years Underground

FROM

.

If you live on the East Coast between Georgia and Connecticut, get ready for the air to be filled with billions of large, buzzing insects known as cicadas, a massive brood of which have been feeding on roots underground for the past 17 years — all in preparation for this one moment.

A small number of the “Brood II” cicadas, which are one of seven different species of the insect, have already begun emerging in some eastern states, according to Magicicada.org, a website run by John Cooley, a cicada expert and research scientist at the University of Connecticut.

By the end of May, the inch-and-a-half-long insects will come out in full force, swarming in massive, noisy clouds up and down the eastern seaboard, reports CBS New York.
