Getting through an airport is a nightmare if you have this insanely cool job

Explosives test at Los Alamos National Laboratory, LANL photo.

Los Alamos National Laboratory scientists talked about using “biology, physics, chemistry, engineering, [and] high-performance computing…to keep America safe” in a Reddit AMA (“Ask Me Anything”) live online chat yesterday. They also talked about the difficulties of getting through airport security because their belongings are often covered in the vestiges of explosives.

So be thankful for this team. Not only do they help keep the US safe, but we can pretty much guarantee that their trip through security is going to be much more annoying than yours. (Full Story)

A Homeland Security Department science and technology program manager is high on new tech at Los Alamos. “Right now, most forms of cryptography can be broken with the right tools — but what if there were a development in the works that could change the game completely?” the DHS official, Michael Pozmantier, writes for TechCrunch. “At Los Alamos National Laboratory, scientists have taken the first step toward exactly that. It’s a device the size of a Starburst candy, which fits on a small circuit board the size of a video card. Inside that unassuming exterior is a crazily fluctuating quantum light field — the quickest and most reliable true random number generator ever made.” (Full Story)

An exclusive look at the world’s largest-ever nuclear cleanup


LANL's Chris Morris on the PBS NewsHour.

TEPCO has turned to a team of scientists and engineers from the Los Alamos National Laboratory for some assistance. They are helping build a device designed to see through the walls of the reactor buildings and hopefully make what looks like three-dimensional X-rays of the reactor cores.

Physicist Chris Morris leads the team. "You can reconstruct the amount of material at the core in the reactor. And we can actually measure if there’s any uranium there, if there’s a lot of uranium there, how much is left." (Full story)



 

Melting of ice wedges adds to Arctic warming

Arctic ice, from VOA

Ice wedges are a particularly cool surface feature in the Arctic tundra. And new research suggests they are melting fast, which is bad news for the ecosystem at the top of the world — and the planet in general.

"The unique structure of ice wedge polygon landscapes promotes ponding of water and the accumulation of vast stores of soil carbon as wetland vegetation dies off seasonally and is buried and frozen over thousands of years" said Cathy Wilson, the Los Alamos National Laboratory geomorphologist.

Millions of earthquakes shake the globe every year, the ground suddenly lurching in response to movements of the tectonic plates that form Earth’s crust.

We still don’t fully understand the details inside faults or how those details might control the location and timing of earthquakes, but geophysicists and computer scientists at Los Alamos National Laboratory and their colleagues are wielding an array of new tools to study the interactions among earthquakes, precursor quakes (often very small earth movements) and faults.

At Los Alamos National Laboratory, we’ve developed a portable MRI, also called Battlefield MRI that uses ultra-low-field magnetic resonance imaging to create images of the brain that can be used in field hospitals for wounded soldiers or in remote villages in developing countries.

Conventional MRI machines use very large magnetic fields that align the protons in water molecules to create magnetic resonance signals, which are detected by the machine and turned into images. The large magnetic fields create exceptionally detailed images, but they are difficult and expensive to make. (Full story)

Surprise nuclear strike? Here's how we'll figure out who did it

Trinitite, the green-hued glass left by the first U.S. nuclear blast, for use in forensic studies. From Science

“Each type of weapon has a distinct fingerprint,” says Michael Pochet, a U.S. Air Force electrical engineer detailed to DTRA. In plutonium bombs, for example, the fissile isotope is plutonium-239, made in nuclear reactors and extracted by reprocessing spent fuel, which contains a mix of plutonium isotopes and other actinides like americium. Detecting those nuclei indicates that the bomb’s core was plutonium.

Their proportions hold clues to the bomb’s history, says Joel Ullom, a physicist at the U.S. National Institute of Standards and Technology in Boulder, Colorado, who, with colleagues at Los Alamos National Laboratory in New Mexico, has developed a superconducting sensor that speedily differentiates plutonium isotopes.

Bolivia’s second largest lake has vanished into thin air. In December, Lake PoopĆ³ became a dry salt pan and its largest lake – Lake Titicaca – is heading towards trouble, too.

This is largely due to the permafrost thawing. When frozen soil thaws, the water can drain, bursting out sideways or disappearing underground. “These ponds are the baby lakes, and if they disappear then we will have no Arctic lakes in the long term,” says Christian Andresen from the Los Alamos National Laboratory.

One weakness of encryption algorithms — one that simply increasing from 128-bit to 256-bit can’t solve — is that they are based on pseudo-random number generators; not truly random number generators.

As Raymond Newell, research scientist at Los Alamos National Laboratory and contributor to Whitewood Encryption Systems's creation, explains, "We take the randomness we create and spread it across the network." (Full Story)

Earth’s radiation belts change wildly with solar storms



Van Allen belts can vary, NASA illustration.

Satellites can short-out if they encounter a surge of radiation in Earth orbit and a new study of the Van Allen belts’ shape — an intensely charged region surrounding our planet — could help better protect them from this highly-charged environment, researchers say.

"The shape of the belts is actually quite different depending on what type of electron you're looking at," said lead author Geoff Reeves, of Los Alamos National Laboratory.

New dates have been obtained for fossils discovered in Ethiopia’s Chorora Formation. Argon dating and paleomagnetic methods, combined with fieldwork, volcanic ash chemistry, and geochronology, suggest that the nine gorilla-like teeth of Chororapithecus abyssinicus, a common ancestor of apes and humans, are younger than previously thought.

“Our analysis of C. abyssinicus fossils reveals the ape to be only eight million years old, younger than previously thought. This is the time period when human and African ape lines were thought to have split, but no fossils from this period had been found until now,” said geologist Giday WoldeGabriel of Los Alamos National Laboratory.
