The more that scientists stare at it, the more a strange signal from the center of the Milky Way galaxy appears to be the result of dark matter annihilation. If confirmed, it would be the first direct evidence for dark matter ever seen.
Dark matter is a mysterious, invisible substance making up roughly 85 percent of all matter in the universe. It floats throughout our galaxy, but is more concentrated at its center. There, a dark matter particle can meet another dark matter particle flying through space. If they crash into one another, they will annihilate each other (dark matter is its own antiparticle) and give off gamma rays.
To search for a dark matter signal, astronomers use NASA’s Fermi Gamma-Ray Telescope to map the gamma radiation throughout the galaxy. Then, they try to account for all known sources of light within this map. They plot the location of gas and dust that could be emitting radiation and subtract that signal from their gamma-ray map. Then they determine where all the stars are and subtract out that light, and so on for every object that might be emitting radiation. Once all those sources are gone, there remains a tiny excess of gamma radiation in the data that no known process can account for.
“The more we scrutinize it, the more it looks like dark matter,” said astrophysicist Dan Hooper of Fermi National Accelerator Laboratory, co-author of a paper that appeared Feb. 26 on arXiv, a website that hosts scientific papers that have yet to go through peer-review.
Paul won 31 percent of the vote (compared with the 25 percent he won last year), beating a crowded field of more than two dozen names, including a number of potential 2016 GOP presidential contenders. He crushed second-place finisher Sen. Ted Cruz (R-Tex.), who came in with 11 percent.
Rather than comment on this, I will leave you with a trailer for what I assume is Rand Paul’s favorite movie of 2013:
I go, because these experiences must be recognized, must be honored. On one of my first trips to northern Uganda, an elderly man told me that if a dying person tells you their story, and it’s not passed on, you’ll be haunted. Well, I do pass on every story that I hear but the knowledge, the awareness, remains to haunt me.
You cannot read anything I have written, Mariella, of course. It will be some years till your judgment of me as a father, as a man, comes to maturity-when these struggles and sacrifices are put into context. When that time comes, please know that I tried to be the best that I could-though I faltered sometimes-that I wanted to make a better world not just for my daughter, but for all the daughters and sons of all the fathers and mothers; that I carried you in my heart everywhere I went; that when I walked through refugee camps, hospitals, schools and saw the eyes of curious child fighters, I saw you. You were with me everywhere. And seeing you, knowing my love for you, I held to the faith that a world could exist where I would want you to live, where men stand up for the women they love.

With this in mind, I sat down to write and was stunned by how easily my own story emerged; surprised, too, by how profoundly the witnessing of hostile acts against women had affected my beliefs about the world, myself, and the role of men (both innocent and guilty) in putting an end to this violent cycle. After “Rescue” was published, I was approached by other men who had stories to tell, from a photojournalist explaining to his six-year-old daughter why he needs to leave her behind for weeks at a time, to photograph raped women in Africa, to a medical doctor tracing his own healing vocation back to a childhood spent watching his mother being beaten by his father.
It became clear to me (as it already was to Eve) that violence against women was not merely a female issue; it was a human dilemma twisting the lives and consciences of men as well; men whose voices needed to be heard in order for the dialogue that began ten years ago with the founding of V-Day to be complete.
In the months to come, we will be presenting — in this space — a series of pieces written by men with the hope of bridging this gender gap.

Despite some sparring with members of the profession during my career, I must confess that one of my earliest ambitions was to become a journalist.
While studying at Wellesley, I hoped to pursue a career that reflected both my interests in journalism and world affairs.
But I was also in love and planned to get married right after graduation, which I did.
Unfortunately, my new husband happened to work for the same newspaper in Chicago that I aspired to write for, which led to a complication.
Shortly after our marriage, one of the editors said to me, “Honey, you may want to be a reporter, but it’s against company policy for both a husband and wife to work here; and it’s against common sense that you would write for a competing paper. So go home and forget about it.”
I did go home, but I didn’t forget a thing.
Conservatives should “make it clear” to Republicans that if they “pass amnesty,” they’re “going on to the death squad with the people who wrecked America,” provocateur/ columnist Ann Coulter told CPAC Saturday.
That comment, which drew laughter and applause, came at the end of a debate with Daily Caller columnist Mickey Kaus, held as “a tribute to ‘Firing Line,’” William F. Buckley’s three-decade TV show. It featured swipes from Coulter at “yuppies” (“in L.A., they have gardeners even when they don’t have gardens”); undocumented immigrants (“people who crossing the border illegally in the back of trucks marked, you know, ‘pico de gallo,’ hiding in barrels, running from the border guard - it’s not like they didn’t know what they were doing was wrong”); Marco Rubio (“all my life I’ve heard “Republicans hate black people - I’ve never seen any evidence of it until I read Marco Rubio’s amnesty bill”); and the poor (“it’s a cruel and Selfish thing…for the upper classes…to refuse to tell poor people ‘keep your knees together before you’re married - that would solve so many of life’s problems.’”)
But to Alexander’s supporters who have followed all of the high-profile cases prosecuted by Corey’s office that have made national news, Corey appears to have a vendetta against Alexander. While Corey’s office is arguing that they are following state precedent, it’s also true that prosecutors have a huge amount of discretion and power. If Corey wanted to, she could easily conclude that three years behind bars for defending yourself from your abuser is enough and send Alexander home after this ugly ordeal and grave injustice.
Most of the arrests came at an off-campus apartment complex, where large crowds began gathering Saturday morning for the annual event, which was started by bars to allow the students to celebrate the holiday before their spring break begins this week.
Police from the city, university and state troopers in riot gear converged on a crowd of about 4,000 people at an apartment complex shortly after noon, police said in a statement Saturday night. Police said party-goers were involved in destruction of property and, as officers began to disperse the crowd, they were pelted with glass bottles, beer cans and snowballs.
After handling the disturbance at the apartment complex, police say several thousand people assembled near a frat house and near an intersection. Authorities said they determined that the gathering became dangerous and out of control, and when officers tried to clear the crowd they again faced people throwing bottles, rocks, cans and snowballs.
Libya’s defense ministry has issued orders to its military authorizing the use of force to stop a North Korea-flagged tanker loading crude oil sold by armed rebels seeking to bypass the Tripoli government, state media said on Sunday.
The rebels, who have seized three major Libyan ports since August to press demands for a greater share of oil revenues and political autonomy, received the tanker on Saturday at the Es Sider port in the volatile east.
The docking and loading of crude escalates a seven-month blockade of key oil ports and is just one facet of deepening turmoil in the OPEC producer, which is struggling to control militias that helped oust Muammar Gaddafi in 2011 but kept their weapons and now challenge state authority.
She took on the role of acting NOAA administrator on Feb. 28, 2013. Prior to that, Sullivan was the assistant secretary of commerce for environmental observation and prediction and deputy administrator for NOAA. In 1993, Sullivan was appointed as NOAA’s chief scientist.
“With her impressive background as a scientist and astronaut and her excellent record of building bridges between diverse environmental stakeholder communities and federal policymakers, Kathy brings a great blend of scientific rigor, team-building skills, and strategic sensibility to the important job of NOAA administrator,” said John P. Holdren, assistant to the president and director of the White House Office of Science and Technology Policy.
Joining the NASA astronaut corps in 1978, she was the first American woman to walk in space.
