Want to start a space colony? Even if you don’t, space agencies across the globe do. Whether it’s a moon base now, à la the Trump administration’s plans for NASA, or a Mars landing later, such a colony will need a lot of power. And given the possibility of light-obscuring dust storms on the Red Planet and the moon seeing an uneven amount of sunlight, solar panels may not cut it. But don’t worry — Los Alamos National Lab has a plan.

It hinges on nuclear power, which, at its most basic, consists of harnessing energy from radioactive elements. (Full story)

and target vessel. LANL Graphic.

The National Nuclear Security Administration (NNSA) has approved Critical Decision-1 (CD-1) for the Advanced Sources and Detectors Project (ASD), a cornerstone of the Enhanced Capabilities for Subcritical Experiments portfolio (ECSE). ASD is a proposed 20-million electron volt (MeV) accelerator that will generate X-ray images, or radiographs, of subcritical implosion experiments for the nuclear weapons program.

“The ECSE portfolio is designed to better understand plutonium when it is subjected to extreme pressure from explosively driven shocks, a central mission need for NNSA’s science-based Stockpile Stewardship Program,” said Thom Mason, Director of Los Alamos National Laboratory. (Full story)




Squashed quantum dots can possibly emit more stable light


Some of the amazing features of the squashed dots are that the spectrally narrow light emitted has a highly stable intensity plus non-fluctuating emission energy. According to the Los Alamos National Laboratory’s new research, the stressed colloidal quantum dots signify a practicable substitute for the current in use nanoscale light sources. Additionally, they earn the title nanoscale, single-particle light sources for further application in medical diagnostics, optical quantum circuits, and ultrasensitive sensors.

In comparison to the conventional dots, the newly produced squashed dots offer great flexibility for bringing about manipulation in the emission color along with the exceptional subthermal, narrow linewidth. (Full story)

A retired Los Alamos National Laboratory biologist thinks he has found the solution to long-term allergy relief.

It’s a lollipop. Specifically, a lollipop that Cliff Han says tackles what he believes is the root cause of environmental allergies, rather than the symptoms. By stabilizing levels of “good” oral bacteria, he says, his product helps “switch off” an overworking immune system that makes people sneeze or cough. (Full story)

Magnetic north just changed. Here's what that means.

Magnetic north has never sat still. In the last hundred years or so, the direction in which our compasses steadfastly point has lumbered ever northward, driven by Earth's churning liquid outer core some 1,800 miles beneath the surface.

“We know that the pole now is moving faster than it has for decades, but how often does that happen in the long historical record?” inquires Geoff Reeves, a space scientist at Los Alamos National Lab. “We don't have any idea. What we know is what it's doing now is different, and that's always exciting scientifically.” (Full Story)



Research team creates bacterial sensor modeled after the immune system

Left to right: Jessica Kubicek-Sutherland, Harshini Mukundan and Aaron Anderson accept their R&D 100 Award, from R&D.

The human innate immune system is capable of detecting all pathogens quickly, sensitively and effectively. It does this by selectively recognizing and binding to pathogen-specific biomarkers—or bacterial calling cards—via a suite of immune receptors.

A team at Los Alamos National Laboratory (LANL) has created a possible solution. They’ve designed a Universal Bacterial Sensor—modeled after the human innate immune system—that mimics the biological recognition of all categories of bacterial pathogens. Requiring less than a drop of blood, it detects all pathogens without prior knowledge of what they might be, before symptom onset and within 15 to 30 minutes. (Full Story)



We need more powerful nuclear engines to explore farther and faster into space

NASA has also investigated making more efficient RTGs called eMMRTGs, or enhanced multi-mission RTGs. But to really take a bigger step forward, we have to look at something new. “Eventually we will need higher-power systems. Only fission can supply that in any type of near-term scenario,” says Los Alamos National Laboratory researcher David Poston.

Poston is the chief reactor designer for Kilopower, a prototype fission reactor that NASA successfully testedlast year. It could provide power over the course of long missions, possibly even for human planetary outposts. “The way we evolved it to being feasible was simplifying things,” says Poston. “We’ve had plenty of space reactor programs over the past 30 years, but they’ve all failed. Mostly because they became too expensive.”  (Full Story)

Sharp turns cause rivers to meander, migrate

 
According to new research by geologists, current river migration models are unnecessarily complicated. The latest analysis, published this week in the journal Geology, showed that a river's rate of migration is closely correlated with the sharpness of its bends.

"The authors' method for relating curvature to migration rate provides a very nice framework for determining where a simple migration model is appropriate," said Jonathan Schwenk, a postdoctoral fellow at Los Alamos National Lab who studies river behavior. "I would love to see this analysis extended to rivers flowing through different environments to really get a sense of the factors that make simple models and the theory diverge from observed migration patterns."

More strategic control of air conditioners could improve the overall efficiency and reliability of the power grid and make it easier to transition to renewable energy, and that’s the goal of a $2.9 million grant University of Michigan researchers have received from the Advanced Research Projects Agency-Energy.

In the experimentation stage, the team will build a small distribution feeder of air conditioners in a warehouse at Los Alamos National Laboratory. With this setup, the team will test the load balancing system to its breaking point, and therefore learn how to prevent such issues from occurring in real life. (Full Story)

Doing work that matters at Los Alamos


From the moment Los Alamos first invented the atomic bomb, the scientists who worked on it knew that its enormous destructive power posed a unique danger to the world and were immediately concerned with how to stop the spread of nuclear weapons.

The laboratory’s nuclear nonproliferation work has focused primarily on detection: How will the United States and our allies know if another country is developing or testing nuclear weapons? How will we know if someone is smuggling nuclear material into or out of the country? (Full story)

“During these first 90 days one thing that has really struck me as I’ve visited the various areas of the Laboratory is the total commitment to the Laboratory’s mission by all Lab staff that I’ve met,” Mason said. “They clearly have a sense that their efforts really matter.”

Mason describes the most enjoyable aspect of his job. “The thing I really like is the variety that comes from the breadth of the institution. I can touch in the course of a day the science, the technology, the operations, the community engagement ... that variety really keeps me engaged,” he said. (Full story)




Celebrate the women behind the periodic table

Darleane Hoffman, from Nature.

Here we spotlight some of the women who revolutionized our understanding of the elements. Marie Curie is the most celebrated, for her double Nobel-prizewinning research on radioactivity and for discovering polonium and radium1. Stories of other women’s roles are scarce.

US chemist Darleane Hoffman made a monumental leap in the early 1970s. She showed that the isotope fermium-257 could split spontaneously — not only after being bombarded with neutrons. The first woman to lead a scientific division at Los Alamos National Laboratory in New Mexico, Hoffman also uncovered plutonium-244 in nature. She trained generations of female scientists.

LANL deploys DataWarp Tech to speed simulations on Trinity


One of Los Alamos National Laboratory’s central missions is guarding the safety, security and reliability of the U.S. nuclear stockpile as part of the National Nuclear Security Administration’s (NNSA) Stockpile Stewardship program. Computer simulation, of course, is key tool in the effort, and LANL uses its Trinity supercomputer (Cray XC40) to run simulations and to explore new technology that could be used to speed simulations.

As LANL points in a description of the issue, “The application runs for extended periods of time — often several months on end. As a result, data flushing to the Lustre file system creates inefficiencies because the application stops completely during the flushing process.” (Full story)
