Los Alamos turns its nuclear weapons power to war on cancer

Eva Birnmbaum (right) talks to NBC News reporter Janet Shamlian. From NBC News.

Hidden amid the mountains and mesas of northern New Mexico lies Los Alamos National Laboratory. It's shrouded in secrecy. Once known simply as Project Y, it was a classified lab where scientists built the atomic bomb.

Now, 70 years later, scientists there still work on nuclear weapons, but they're also using some of that same knowledge to battle cancer.

NBC News got exclusive access to the secure facility, where physicist Eva Birnbaum is working to use radioactive elements to battle cancer. (Full Story)

Mars Rover finds changing rocks, surprising scientists

After arriving at a spot the scientists named Marias Pass, an intersection between the older mudstone and younger sandstone near the base of the mountain, Curiosity spied a patch of light-toned bedrock, part of the mudstone. It fired a laser to vaporize the rock in several places; the instrument identifies the constituent elements from the colors of light given off.

“The science team decided to make the rare decision to go back and investigate this more,” said Jens Frydenvang, a member of the science team from Los Alamos National Laboratory and from the University of Copenhagen. (Full Story)



Curiosity Rover finds piles of silica on Mars

NASA says its Curiosity rover has found very high concentrations of silica on the red planet.  Explanations for the high silica levels "all require considerable water activity," says Jens Frydenvang of Los Alamos National Laboratory and the University of Copenhagen. He adds, "and on Earth high silica deposits are often associated with environments that provide excellent support for microbial life."

Silica, NASA reminds us, "is a rock-forming chemical containing silicon and oxygen, commonly found on Earth as quartz." It was found in an area that also had significantly higher levels of hydrogen than other parts of Mars explored by Curiosity. (Full Story)





Rocks rich in silica present puzzles for Mars Rover team

Seven months ago, Curiosity approached "Marias Pass," where two geological layers are exposed in contact with each other. The rover's laser-firing instrument for examining compositions from a distance, Chemistry and Camera (ChemCam), detected bountiful silica in some targets the rover passed on its way to the contact zone. The rover's Dynamic Albedo of Neutrons instrument simultaneously detected that the rock composition was unique in this area.

"The high silica was a surprise -- so interesting that we backtracked to investigate it with more of Curiosity's instruments," said Jens Frydenvang of Los Alamos National Laboratory in New Mexico and the University of Copenhagen, Denmark. (Full Story)

Flu season will peak at an unusual time this winter

A team of mathematicians and computer scientists at the Los Alamos National Laboratory in New Mexico say it’s probable that this season’s flu cases will spike in February. That’s in contrast to the past three years, when the flu peaked in mid-to-late-December.

Scientist Sara Del Valle, who leads a group tracking flu cases for the federal government, said her team looks at two types of data to make their predictions: the number of ‘flu-like’ virus symptoms being reported at doctor’s offices, and actual lab samples of the flu. (Full Story)

Could UN climate pact work? This is one way we’d actually know

The need is highlighted by China's recent acknowledgement that it had underreported its carbon dioxide (CO2) emissions from burning coal by 17 percent, notes Mavendra Dubey, a climate researcher at Los Alamos National Laboratory.

“The good news is that everybody agrees that climate change is a problem,” says Los Alamos’s Dr. Dubey. “Now we have to verify and monitor – not punitive, but to build capacity and evidence that we're moving in the right direction.” (Full Story)

'Hoverboard' scooter fires: Faulty batteries may be to blame

Image from Live Science.

Lithium-ion batteries, first commercialized by Sony Corporation in 1991, give power to countless electronics, including cellphones, laptops, power tools and children's toys. Lithium itself is fairly dangerous; it can explode if it comes into contact with oxygen or water. But Sony developed a way to contain the metal, said Lloyd Gordon, the chief electrical safety officer at Los Alamos National Laboratory in New Mexico.

The invention keeps lithium ions in "some sort of a suspension or chemical so that it's never pure lithium," Gordon told Live Science. (Full Story)




New model tracks gases for underground nuclear explosion detection

Scientists at Los Alamos National Laboratory have developed a new, more thorough method for detecting underground nuclear explosions (UNEs) by coupling two fundamental elements--seismic models with gas-flow models--to create a more complete picture of how an explosion's evidence (radionuclide gases) seep to the surface.

Magnetic field helps qubit electrons store information longer

Semiconductor nanostructures.

Physicists at the Technical University of Munich, the Los Alamos National Laboratory and Stanford University (USA) have tracked down semiconductor nanostructure mechanisms that can result in the loss of stored information – and halted the amnesia using an external magnetic field. The new nanostructures comprise common semiconductor materials compatible with standard manufacturing processes.

Quantum bits, qubits for short, are the basic logical elements of quantum information processing (QIP) that may represent the future of computer technology. (Full Story)



New seed treatment accelerates nutrient uptake

The plant-growth biological technology in Take Off ST is a discovery made by the Los Alamos National Laboratory in New Mexico and made into a seed treatment by Verdesian Life Sciences for use on soybeans, corn and wheat to accelerate the crop plant’s natural ability to acquire nutrients and put them to work during seed germination and early plant growth.

According to Verdesian data, tests on wheat treated with Take Off ST showed nitrogen content increased 48 percent compared to the untreated crop. (Full Story)

Los Alamos scientist describes Antarctica Meteor Hunt: Mind blown in 60 seconds


There are plenty of attempts at making science accessible. Researchers have tried to use simple words, interpretive dance, or really cool videos to explain complex scientific concepts. This new one might have all of those beat, at least when it comes to speed.

Los Alamos National Laboratory has unveiled a video where they challenged staff scientist Nina Lanza of LANL’s Space and Remote Sensing group describe her upcoming trip to Antarctica to hunt for meteorites in just 60 seconds. (Full story)

 Sinha discusses acoustics for energy, national security challenges

    
Laboratory fellow Dipen Sinha of discusses acoustics and its applications, including how it is possible to use sound to solve problems in health, national security and industry, in a Santa Fe Radio Cafe interview.

“I take advantage of the nature of sound waves and often manipulate these waves to solve technically challenging problems related to energy and national security,” Sinha said. “How an object vibrates also tells a lot about it. (Full story)

 Sequencing algae’s genome may aid biofuel production

Haptophytes Chrysochromulina, from Biomass.

Scientists have sequenced the complete genetic makeup of haptophytes algae. First author Blake Hovde is now a postdoc at Los Alamos National Laboratory. Co-authors include LANL’s Ramesh Jha and Shawn Starkenburg.

The researchers hope to better understand haptophytes and perhaps transform them into an important new tool for aquaculture, biofuel production and nutrition. They discovered that a haptophyte type, called Chrysochromulina, would make an ideal subject for investigating how algae make fat, a process important for nutrition, ecology and biofuel production.

One representative project, run by Tustin, Calif.–based company Magneto-Inertial Fusion Technologies, is designed to “pinch” a plasma with an electric current until it compresses itself enough induce fusion. The approach has pedigree: scientists at Los Alamos National Laboratory used the pinch technique in 1958 to create the first sustained fusion reaction in a laboratory. (Full Story)
