About 140 cases of missing or unauthorized use of nuclear and radioactive material were reported to the U.N. atomic agency in 2013, highlighting the challenges facing world leaders at a nuclear security summit next week.
Any loss or theft of highly enriched uranium, plutonium or different types of radioactive sources is potentially serious as al Qaeda-style militants could try to use them to make a crude nuclear device or a so-called "dirty bomb", experts say.

Scientists offer new 360-degree glimpse of the Milky Way galaxy
In creating a zoomable, 360-degree portrait of the Milk Way galaxy, University of Wisconsin scientists have offered new insight into the structure and contents of the spiral star system.
To create the holistic portrait, Wisconsin astronomers pieced together 2 million cosmic images collected by NASA’s Spitzer Space Telescope. The team unveiled their impressive galactic collage today at a TED conference in Vancouver.
While the seas rise in the Outer Banks and elsewhere in NC, science treads water
There’s not much dispute these days, up and down the coast, about whether the ocean is rising. The question is: How high will it go here, and how fast?
North Carolinians must wait until 2016 for an official answer. That’s the law.
After promoters of coastal development attacked a science panel’s prediction that the sea would rise 39 inches higher in North Carolina by the end of this century, the General Assembly passed a law in 2012 to put a four-year moratorium on any state rules, plans or policies based on expected changes in the sea level. The law sets guidelines under which the Coastal Resources Commission, a development policy board for the 20 coastal counties, will formulate a new sea-level prediction to serve as the official basis for state planners and regulators.
Alex Baer: This Computes Just Fine, Thank You
Enjoy this sight experience while you can. Before long, robots will also be reading the news that they, themselves, produce.
In fact, give it 10 or 20 years, and half of all jobs in the U.S. will be held by machines. The Oxford study does not provide details on other ripples through the financial and social strata. This leaves a lot of room for paranoid imagination, also known as alternately laughing at improbabilities and scaring the bejesus out of yourself.
When it comes to robot workers, perhaps the adage is right: It's not if you are paranoid, but if you are paranoid enough. This is not your grandfather's replacement-by-robots fear, not even its reality, as it has already worked out in the world. Pick your metaphor: This time it's serious as a heart attack, this program's on steroids, it's a whole new level of...
US tech giants knew of NSA data collection
The senior lawyer for the National Security Agency stated unequivocally on Wednesday that US technology companies were fully aware of the surveillance agency’s widespread collection of data, contradicting months of angry denials from the firms.
Rajesh De, the NSA general counsel, said all communications content and associated metadata harvested by the NSA under a 2008 surveillance law occurred with the knowledge of the companies – both for the internet collection program known as Prism and for the so-called “upstream” collection of communications moving across the internet.
Feds accused of steering funding to anti-pot researchers
As the nation’s only truly legal supplier of marijuana, the U.S. government keeps tight control of its stash, which is grown in a 12-acre fenced garden on the campus of the University of Mississippi in Oxford.
From there, part of the crop is shipped to Research Triangle Institute in North Carolina, where it’s rolled into cigarettes, all at taxpayer expense.
U.S. says Toyota to pay $1.2 billion over safety issues
Toyota Motor Corp will pay a record $1.2 billion to resolve a criminal investigation into its handling of consumer complaints over safety issues, the U.S. Justice Department said on Wednesday.
Toyota admitted it misled American consumers by concealing and making deceptive statements about two safety issues, each of which caused a type of unintended acceleration, the Justice Department said.
Was the Los Angeles Earthquake Caused by Fracking Techniques?
Was the 4.4-magnitude earthquake that rattled Los Angeles on Monday morning caused by fracking methods? It's hard to say, but what's clear from the above map, made by Kyle Ferrar of the FracTracker Alliance, is that the quake's epicenter was just eight miles from a disposal well where oil and gas wastewater is being injected underground at high pressure.
Don Drysdale, spokesman for the state agency that oversees California Geological Survey, told me that state seismologists don't think that the injection well was close enough to make a difference (and the agency has also raised the possibility that Monday's quake could have been a foreshock for a larger one). But environmental groups aren't so sure.
The Toxins That Threaten Our Brains
Forty-one million IQ points. That’s what Dr. David Bellinger determined Americans have collectively forfeited as a result of exposure to lead, mercury, and organophosphate pesticides. In a 2012 paper published by the National Institutes of Health, Bellinger, a professor of neurology at Harvard Medical School, compared intelligence quotients among children whose mothers had been exposed to these neurotoxins while pregnant to those who had not.
Bellinger calculates a total loss of 16.9 million IQ points due to exposure to organophosphates, the most common pesticides used in agriculture.
