As if bark beetles and low river water levels weren’t enough, there’s another local impact of drought in New Mexico that we can think about – Valley fever. It’s a dust-borne fungal infection, common in the San Joaquin Valley of California and parts of Arizona, but more and more likely to move north through New Mexico, affecting large population centers, such as Albuquerque and Santa Fe, as heat and drought make our soils more welcoming to the fungus.

A 2019 study by a Los Alamos scientist and researchers at the University of California, Irvine documented this expansion, projecting that the fungal infection’s range will likely more than double in the United States, with the list of affected states jumping from 12 to 17, and the number of individual Valley fever cases predicted to grow by 50% by the year 2100.

The next coronavirus nightmare is closer than you think

Coronavirus illustration.

Global warming can accelerate displacement by thawing, burning, flooding, or drying out habitats in response to hotter temperatures and stronger storms. “As habitats change and people move and wildlife moves, they’re going to be coming into contact more with each other,” said Jeanne Fair, a biosecurity and public health expert at Los Alamos National Laboratory in Los Alamos, New Mexico. Increasingly close contact, in turn, significantly raises the risk that an animal disease will spill over into humans. (Full story)

Carbon Capture: Solved by Software?

SimCCS software shows potential carbon sources (red dots), sinks (blue dots), and proposed optimal pipelines (green). LANL image.

Most scenarios for a clean-energy future rely on carbon capture—taking CO2 emissions from their sources, such as power plants, then sequestering them underground or converting the carbon into a usable product. For example, at the National Carbon Capture Center in Alabama, where the DOE has tested the technology since 2009, equipment on the coal power plant’s smokestacks separates the carbon from other emissions. The byproduct is then transported in the form of liquid to a storage sink.

SimCCS is a software program developed at Los Alamos National Laboratory to solve the problem of high transportation costs between emitter and sink. The open-source software, which is also being developed and expanded on by universities across the country, finds the most efficient route between a carbon-emitting plant and a sink. (Full Story)

Where Australia's smoke goes to die

Smoke from Australia's megafires has already traveled tens of thousands of miles around Earth. "It circles the globe in roughly a week," said Manvendra Dubey, who researches air pollution and wildfire smoke at Los Alamos National Laboratory.

Much of this carbon dioxide will likely stay in the atmosphere, where it will live for hundreds of years. Though, plants on land and plankton in the ocean will consume some of this carbon dioxide — though exactly how much is unknown. "It will have climatic consequences," said Dubey. (Full Story)

New high-energy gamma-ray sources found in the galaxy

New sources of high-energy gamma rays, HAWC image.

Most of the gamma rays scientists have observed in the past have been lower-energy gamma rays. But with the High-Altitude Water Cherenkov Gamma-Ray Observatory (HAWC) in Mexico, which was completed a few years ago, physicists are now able to survey the entire sky for gamma rays with especially high energies.

These are actually the highest-energy gamma rays ever seen,” said Brenda Dingus, a physicist at Los Alamos National Laboratory and a senior member of the HAWC collaboration.

The new high-energy gamma-ray sources are all located near pulsars — this makes the researchers wonder whether the high-energy gamma rays are a common feature of pulsars, says Kelly Malone, an LANL physicist and lead author of the new paper. (Full Story)

“These are actually the highest-energy gamma rays ever seen,” said Brenda Dingus, a physicist at Los Alamos National Laboratory and a senior member of the HAWC collaboration. Some of these gamma rays have about 10 times the energy of the most energetic gamma rays that have been created in particle accelerators on Earth.

Interestingly, the new high-energy gamma-ray sources are all located near pulsars — extremely magnetic rotating neutron stars that shoot jets of radiation through space. This makes the researchers wonder whether the high-energy gamma rays — and the cosmic rays that produced them — are a common feature of pulsars, says Kelly Malone, an LANL physicist and lead author of the new paper.

Why the Taal volcano's eruption created so much lightning

Thunder clapped and lightning streaked through the dark column of volcanic ash. From Mashable.

Volcanic lightning, however captivating, is common, explained Sonja Behnke, a scientist at Los Alamos National Laboratory who researches these volcanic phenomena and has repeatedly observed volcanic lightning in places like Iceland and Japan.

First, the volcanic ash needs an electric charge. When a volcano erupts explosively it ejects exploded particles of molten rock into the air, which becomes volcanic ash. In the towering plume of ash, these billions of particles start colliding and rubbing against each other, which creates charged volcanic particles. It's similar to how you create static electricity by rubbing socks on carpet. "The ash gets charged as the volcano is erupting," said Behnke. (Full Story)

Why premature claims of life on Mars hurt science

Most scientists aren’t surprised when some people come up with a sci-fi explanation for an image from another planet. After all, humans evolved to find recognizable patterns amid chaos. There’s even a word for it: pareidolia. But what we don’t expect is for fellow scientists—those who have been trained in the scientific method—to make those claims. When they do, it hurts science as a whole. (Full Story)

New Mexico faces worst flu season in a decade

Experts at Los Alamos National Lab (LANL) say this is the worst flu New Mexico has seen in a decade. The most recent report from the New Mexico Department of Health (NMDOH) shows the flu is hitting hard all across the state.

"We're just seeing elevated flu activities kind of everywhere," said Dave Osthus, who created last year's Centers for Disease Control and Prevention (CDC) flu forecast model. "And the main reason for that is influenza A and influenza B, two different strands of influenza, are sort of ramping up at the same time." (Full Story)

Scientists at Los Alamos National Laboratory have incorporated meticulously engineered colloidal quantum dots into a new type of LED containing an integrated optical resonator, which allows the LEDs to function as lasers.

The researchers demonstrated an operational LED that also functioned as an optically pumped, low-threshold laser. To achieve those goals, they incorporated an optical resonator directly into the LED architecture without obstructing the charge-carrier flows into the quantum dot emitting layer. (Full Story)

An interesting solution to [the problem of manmade objects in orbit] being developed at Los Alamos National Laboratory is ELROI – the Extremely Low Resource Optical Identifier. We spoke with David Palmer, a scientist at the lab who is developing ELROI, to learn more about this technology.

ELROI (which stands for Extremely Low Resource Optical Identifier) is our solution. This is a little flashing light that can be built into a solar-powered package the size of a Scrabble tile. The flashing light can be seen with a small telescope on the ground and its blinks encode a “license plate number” that tells you exactly which satellite it is. (Full Story)

What do rocks and explosives have in common?

Like rocks, high explosives have curious acoustic behavior, LANL images.

The definitive way to test an aging detonator in the U.S. nuclear stockpile is to fire it. But this destroys the detonator, and it doesn’t reveal much about what impact time has on the high explosives inside.

“Getting information on the high explosive inside those detonators is either really difficult or not possible,” says explosives chemist Peter Schulze. Even so, answering this question—will an aged detonator still work as intended?—is vital to the Los alamos National Laboratory’s mission. (Full Story)
