By listening to the acoustic signal emitted by a laboratory-created earthquake, a computer science approach using machine learning can predict the time remaining before the fault fails.

“At any given instant, the noise coming from the lab fault zone provides quantitative information on when the fault will slip,” said Paul Johnson, a Los Alamos National Laboratory fellow and lead investigator on the research, which was recently published in Geophysical Research Letters.

Gevo and Los Alamos to collaborate on high energy denisity biofuels

News has emerged from Gevo (GEVO) in Colorado and New Mexico’s Los Alamos National Lab that the two will collaborate to improve the energy density of Gevo hydrocarbon products to meet product specifications for tactical fuels for specialized military applications such as RJ-4, RJ-6 and JP-10, which are currently purchased by the US Department of Defense (DoD).

High energy-density fuels are currently used in air and sea-launched cruise missiles used by the US military forces. If this project is successful in scaling the fuels cost-effectively, there may be an even broader application in the general aviation sector, enabling higher energy density jet fuel that would provide superior mileage to traditional aviation fuels.

LANL seismologist doing breakthrough earthquake research

Researchers may be getting closer to one day being able to predict the next earthquake. Los Alamos National Labs seismologist Paul Johnson says this is breakthrough research.

“We’re learning new things about the system that we didn’t know existed,” he said.  Johnson and a researcher from Pen-State are using a so-called earthquake machine to make quakes in a lab.

Johnson is collecting sound information from that machine using a stethoscope of sorts. What is new here is the use of machine learning or artificial intelligence. (Full Story)



Water in one dimension

Water molecules (red and white balls) forming a chain in a carbon nanotube, from the University of Antwerp.

Single-walled carbon nanotubes act like tiny straws that are so narrow that water confined within cannot freeze into its normal crystal-like structure. For the first time, scientists observed that at a cool 150 K, these molecules go through a quasiphase transition. In this transition, the molecules orient themselves in a highly structured, classically hydrogen-bonded arrangement.

Clean water is vital to people, crops and livestock. Technologies using carbon nanotubes may benefit water purification and desalination. Creating such devices demands knowing how water confined in such tubes behaves.

The team of scientists includes Xia Ma, Han Htoon, and Stephen K. Doorn of the Center for Integrated Nanotechnologies at Los Alamos. (Full Story)

Los Alamos is one of just a few places in the world that can perform neutron CT – 3-D imaging – with X-ray CT that yields unique insights into dense objects, more than can be gleaned by either method alone.

With these techniques, Los Alamos researchers create 3-D images and animations of various materials and components, inside and out. Typically, scanning work supports the Lab’s primary mission of ensuring the safety, security and reliability of the nation’s nuclear stockpile, for which the medical X-ray variety also does not work, but as a user facility with unique imaging capability, LANSCE is also available to outside researchers for a variety of projects.

Pew! Pew! Curiosity’s ChemCam zaps a half million Martian rocks

Late last Tuesday, the ChemCam instrument that sits atop NASA’s Mars Curiosity rover fired its 500,000th shot at a Martian rock. That’s big news for the ChemCam team at Los Alamos National Laboratory, which developed the instrument in conjunction with CNES (Centre National d’√Čtudes Spatiales) in France and continues to help direct operations. Data collected from ChemCam has helped quantify elements like hydrogen, boron, and manganese in Martian rocks, which revealed that the Red Planet was habitable in its ancient past. (Full Story)


Hunt is over for one of the 'Top 50 Most-Wanted Fungi'

The “mystery” fungus, LANL image.

“Working estimates tell us that there should be more than 5 million species of fungi,” said Cheryl Kuske, a Los Alamos scientist on the project. “We have really only identified and fully described 100,000 of them, though, and new DNA sequencing capabilities show us that many, many specimens in research collections are uncharacterized. Solving this particular mystery shows the potential value of using environmental sequencing to guide taxonomic and ecological discovery.” (Full Story)

Deep waters spiral upward around Antarctica

Three-dimensional upward spiral of North Atlantic deep water. From MIT.

Through observations and modeling, scientists have long known that large, deep currents in the Pacific, Atlantic and Indian oceans flow southward, converging on Antarctica. After entering the Southern Ocean they overturn — bringing water up from the deeper ocean — before moving back northward at the surface.

A team including scientists from Los Alamos National Laboratory published research in the journal Nature Communications, which reveals that strong eddies, caused by topographical interactions at five locations within the current circling Antarctica, play a major role in this upwelling process.

Collider serves up drop of primordial soup

Reconstructed particle tracks picked up by the detector, from BNL.

A tiny drop of an exotic ultra-hot "soup" that permeated the universe for an instant immediately after the Big Bang appears to have been created in collisions between gold nuclei and deuterons at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory.

One such signature is the abundance and flow pattern of different types of particles emitted in the collisions. Collaboration member Darren McGlinchey of Los Alamos National Laboratory says that abundance data provide information on the temperature of a QGP or quark–gluon plasma. (Full Story)
