Did Neutrinos Really Break Light Speed?
Last week, scientists at the Gran Sasso National Laboratory in Italy claimed to observe neutrinos travelling faster than the speed of light. Now teams are preparing to test the claim.
What's the Latest Development?
Last week, a team of scientists at the Gran Sasso National Laboratory in Italy claimed to have observed neutrinos, subatomic particles that have a small but non-zero mass, travelling faster than the speed of light. "Physicists, for the most part, suspect that an unknown systematic error lies behind [the team's] startling result. But nothing obvious has emerged, and many see the experiment as a tour de force because of its high precision." In March 2011, the team at Gran Sasso observed neutrinos arriving to a fixed point faster than light would have. After testing the results for six month, they went public.
What's the Big Idea?
If the researchers' claim is correct, it would invalidate Albert Einstein's principle that matter cannot achieve light speed, upending one of the most accepted premises of modern physics. But not everyone at the Italian lab agreed to sign their name to the experiment's results. Physicist Caren Hagner declined to confirm the results her team had recorded because she wanted more time to validate the startling conclusion. Teams of physicists around the world are currently calibrating their own particle accelerators to test Gran Sasso's results.

In his final years, Martin Luther King, Jr. become increasingly focused on the problem of poverty in America.
- Despite being widely known for his leadership role in the American civil rights movement, Martin Luther King, Jr. also played a central role in organizing the Poor People's Campaign of 1968.
- The campaign was one of the first to demand a guaranteed income for all poor families in America.
- Today, the idea of a universal basic income is increasingly popular, and King's arguments in support of the policy still make a good case some 50 years later.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
For Damien Echols, tattoos are part of his existential armor.
- In prison Damien Echols was known by his number SK931, not his name, and had his hair sheared off. Stripped of his identity, the only thing he had left was his skin.
- This is why he began tattooing things that are meaningful to him — to carry a "suit of armor" made up the images of the people and objects that have significance to him, from his friends to talismans.
- Echols believes that all places are imbued with divinity: "If you interact with New York City as if there's an intelligence behind... then it will behave towards you the same way."
