Science versus the 'Horatio Alger myth'

Horatio Alger was a prolific 19th-century American writer, from Wikipedia.

In a new study published today in the journal PLOS ONE, Los Alamos National Laboratory scientists have taken a condensed matter physics concept usually applied to the way substances such as ice freeze, called "frustration," and applied it to a simple social network model of frustrated components. They show that inequality of wealth can emerge spontaneously and more equality can be gained by pure initiative.

It's a computer-modeling exploration of the 19th-century Horatio Alger theme, whereby a motivated young person overcomes poor beginnings and lives the "rags to riches" life thanks to strength of character. "Most theories of wealth inequality rely on social stratification due to income inequality and inheritance," said Cristiano Nisoli, of the Physics of Condensed Matter and Complex Systems group at Los Alamos and lead author of the study.

To determine the rate of SEUs in 16-nanometer chips, the Vanderbilt researchers took samples of the integrated circuits to the Irradiation of Chips and Electronics (ICE) House at Los Alamos National Laboratory. There they exposed them to a neutron beam and analyzed how many SEUs the chips experienced. Experts measure the failure rate of microelectronic circuits in a unit called a FIT, which stands for failure in time. One FIT is one failure per transistor in one billion hours of operation.

Physics greats of the 20th century mixed science and public service

Enrico Fermi, from Science News

When he arrived in the United States in 1939, Fermi almost immediately went to work studying nuclear fission, discovered only weeks earlier in Hitler’s Germany. Eventually Fermi took a major role in the Manhattan Project, leading the team that first demonstrated a controlled nuclear fission chain reaction.

Fermi, a foreigner, assumed a lead role because he was so widely recognized among the world’s physicists as infallible — hence his nickname “the pope.” In The Pope of Physics, Gino Segrè and Bettina Hoerlin chronicle Fermi’s life and science with insight and rich detail. (Full Story)

Can artificial intelligence predict earthquakes?

Image from SciAm.

So far, no one has found a reliable way to forecast earthquakes, even though many scientists have tried. Some experts consider it a hopeless endeavor. “You’re viewed as a nutcase if you say you think you’re going to make progress on predicting earthquakes,” says Paul Johnson, a geophysicist at Los Alamos National Laboratory. But he is trying anyway, using a powerful tool he thinks could potentially solve this impossible puzzle: artificial intelligence. (Full story)

That work brought me to the HAWC team at Los Alamos, where I could pursue the deep mystery of dark matter.

One of our searches uses this unusual telescope to look for gamma rays from relatively near dwarf galaxies. They’re unusually dim given the number of stars in them and are known dark matter hangouts. If we do see gamma rays coming from them, that would be a smoking gun for dark matter interactions. (Full story)

Mindful of the danger, the nation has developed a plan to support electric utilities in defending against severe geomagnetic storms. As part of that plan, space scientists at Los Alamos National Laboratory are researching the credible scenarios that could lead to large impacts. Los Alamos has been studying space weather for more than 50 years as part of its national security mission to monitor nuclear testing around the globe, and part of that work includes studying how the radiation-saturated environment of near space can affect technology and people.

Calls for space nuclear power are not new. In fact, numerous reactor concepts have been proposed in the past. Their development is often dampened by the perception that nuclear is too hard, takes too long and costs too much.

Los Alamos National Laboratory, in partnership with NASA Research Centers and other DOE National Labs, is developing and rapidly maturing a suite of very small fission power sources to meet power needs that range from hundreds of Watts-electric (We) to 100 kWe. These designs, commonly referred to as kiloPower reactors, are based on well-established physics that simultaneously simplifies reactor controls necessary to operate the plant and incorporates inherent safety features that guard against consequences of launch accidents and operational transients.

Featured R&D 100 Award winner: Entropy Engine

A portion of the engine’s circuitry,

LANL image.

The Entropy Engine, developed by Los Alamos National Laboratory and Whitewood Encryption Systems, is a computer hardware system that uses quantum mechanics to generate an inexhaustible supply of pure random numbers at speeds of 200 megabits per second. The unpredictability and speed of such entropy provides the highest possible level of defense because the quantum processes used in this technology are irreducibly random. Modern cryptosystems rely on high-quality randomness, consuming surprisingly high quantities of random numbers to generate their keys and perform cryptographic operations. (Full story)

US government agency pops 16 years of solar weather data online

Solar flares influence space weather, from The Register.

National Oceanic and Atmospheric Administration has released 16 years' worth of GPS solar weather data gathered by the Los Alamos National Laboratory for all comers.

Los Alamos explains the release is designed to help researchers create and refine models for understanding and predicting solar weather, to better-protect “satellites, aircraft, communications networks, navigation systems, and [the] electric power grid”.

The sensors measure the energy and intensity of electrons and protons trapped in the Earth's magnetic field to form the Van Allen radiation belts. Each of the 23 sensors in the GPS constellation measures the largest radiation belt every six hours. (Full Story)

Keeping nuclear materials secure in an uncertain world

The Atoms for Peace tour, from the LANL Archives.

Keeping nuclear materials out of the hands of bad actors is critical to keeping the world safe from nuclear attack. To do that requires a team of people who are deployed to countries all over the world to inspect their nuclear-related operations.

These inspectors – from the International Atomic Energy Agency (IAEA) based in Austria – make sure the nuclear materials a country possesses are being used for peaceful purposes (such as for energy or medicine), and not diverted for use in weapons. But how do the inspectors know what to look for? They come to Los Alamos National Laboratory to learn how. (Full Story)

Creating family trees for disease-causing microbes could help control outbreaks

A study examining the origins of AIDS recently made headlines for debunking the infamous myth that Gaetan Dugas, the French-Canadian flight attendant dubbed “Patient Zero,” brought the AIDS pandemic to North America.

The international team of researchers sequenced the genomes of HIV viruses that had been recovered from more than 2,000 blood samples taken in the late 1970s — before AIDS had been identified in the United States. By comparing those sequences to other strains of HIV in the Los Alamos National Laboratory HIV database, the scientists were able to build a family tree of the disease, also known as a phylogeny.

Sixteen years of data about solar weather

The orbital planes in which GPS satellites

travel around Earth, LANL image.

For years, the satellites of America's Global Positioning System have been carrying sensors that measure the weather in space. The information has been kept by the military, which manages the satellites, because solar storms and other space weather can damage satellites.

Today, as the result of an executive order signed last October, the government released 16 years of that space weather data to the public for the first time. "It's really an unprecedented amount of information," explained Marc Kippen, a program manager at Los Alamos National Laboratory, where the sensors were designed. (Full Story)

Los Alamos releases 16 years of GPS solar weather data

susceptibility to space weather. NASA Illustration.

It’s not often that a scientific discipline gains a 23-satellite constellation overnight. But today, space weather scientists are reaping such a windfall, as the Los Alamos National Laboratory in New Mexico has released 16 years of radiation measurements recorded by GPS satellites.

Although billions of people globally use data from GPS satellites, they remain U.S. military assets. Scientists have long sought the data generated by sensors used to monitor the status of the satellites, which operate in the heavy radiation of medium-Earth orbit and can be vulnerable to solar storms. But few have been allowed to tap this resource. (Full story)

Physicists seek neutron lifetime’s secret

Two methods used for measuring the neutron lifetime disagree, leaving scientists uncertain about the subatomic particle’s true longevity.  One technique involves containing chilled neutrons in a trap, or “bottle,” waiting awhile, and counting the remaining neutrons to determine how many decayed.

One drawback of typical bottle experiments is that neutrons can be absorbed or otherwise lost when they hit the wall of the bottle. So physicist Robert Pattie, of the Los Alamos National Laboratory in New Mexico, and colleagues are working on an updated bottle-style measurement using a magnetic field. (Full Story)
