The solace of quantum
Eavesdropping on secret communications is about to get harder

A third project, organised by Jane Nordholt of Los Alamos National Laboratory, has just demonstrated how a pocket-sized QKD transmitter called the QKarD can securesignals sent over public data networks to control smart electricity grids. Smart grids balance demand and supply so that electricity can be distributed more efficiently. (full story)

Our Endangered Nuclear Weaponeers
No more nukes means no more experts, and their talents have kept us safe.

It takes a nuclear weaponeer to stop a nuclear weaponeer. And I should know.

In the 1990s, I designed nuclear bombs at Lawrence Livermore National Laboratory. In the 2000s at Los Alamos, I ran one of the largest programs to reduce thethreat of weapons of mass destruction, directing hundreds of professionals who had worked for decades on all aspects of nuclear weapons. The background, experience and judgment of these weaponeers were responsible for successfully mitigating and preventing various nuclear threats, details of which are still classified. (full story)

Researchers Explain Magnetic Field Misbehavior in Solar Flares: The Culprit is Turbulence

When a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flowaway in lock-step with the particles, whole and unbroken. Instead, the lines sometimes break apart and quickly reconnect in a way that has mystified astrophysicists.

But in a paper published in the May 23 issue of the journal Nature, an interdisciplinary research team led by a Johns Hopkins mathematical physicist says it has found a key to the mystery. The culprit, the group proposed, is turbulence -- the same sort of violent disorder that can jostle a passenger jet when it occurs in the atmosphere. Using complex computer modeling to mimic what happens to magnetic fields when they encounter turbulence within a solar flare, the researchersbuilt their case, explaining why the usual rule did not apply.

U.S. weapons-grade uranium shipments to Chalk River near end

The U.S. National Nuclear Security Administration applied last week to Washington regulators for a new license to export seven kilograms of highly-enriched uranium (HEU) to Canada. Approval seems assured.

The HEU will be used as “target” material and irradiated in core of the NRU research reactor to produce six varieties of radioactive isotopes for life-saving nuclear medicine.

The U.S. has promising research underway too. The Los Alamos National Laboratory, for one, announced last week that for the first time, irradiated uranium fuel from has been recycled and reused for molybdenum-99 (Mo-99) production, with virtually no losses in Mo-99 yields or uranium recovery. Tc99m is a decay product of Mo-99. (full story)

NASA Confirms That Curiosity Found An Ancient Martian Stream

Last year, NASA announced that the Curiosity rover had found preliminary evidence of an ancient streambed, indicating that water once flowed freely on Mars. After a few more months of study, that preliminary announcement has been confirmed – Curiosity has found the remains of an ancient stream.

In addition, Curiosity’s ChemCam  also took pictures of the rocks. ChemCam is a high powered laser that is used to blast tiny parts of the rock. The camera in ChemCam then captures the photons that are produced as a result. The spectra produced tell scientistswhat the chemical compositions of the rock are. (full story)

Securing power grids from cyber attacks key to energy security

Securing power grids against cyber attacks is going to pose  critical security challenge. Speaking to top US energy executives near Washington, Charles McMillan, director of the US Los Alamos National Laboratory, said, that securing the electrical grid is becoming more serious.

Scientists are pretty pleased with the results so far, said Roger Wiens, a Los Alamos National Laboratory geochemist, who is among the international gaggle of researchers using Curiosity’s data to learn more about the Red Planet. Wiens will talk about Mars, the rover mission and what scientists have learned so far during a free talk Tuesday, May 14, at 7 p.m. at the James A. Little Theater in Santa Fe. (full story)

The solace of quantum

Jane Nordholt of Los Alamos National Laboratory has just demonstrated how a pocket-sized QKD transmitter called the QKarD can secure signals sent over public data networks to control smart electricity grids.

Smart grids balance demand and supply so that electricity can be distributed more efficiently. This requires constant monitoring of the voltage, current and frequency of the grid in lots of different places—and the rapid transmission of the results to control centres. That transmission, however, also needs to be secure in case someone malicious wants to bring the system down. (Full Story)

Top-secret Los Alamos National Laboratory has not been deliberately keeping a secret about its new hyper-secure information technology. It’s just that the lab’s ongoing quantum communications project, which has already set world records and won important science prizes, has been undergoing another evolution from theory and experimentation to practice.

Cyber attacks, currently a serious threat to the American energy system, are set to become only more substantial in the coming years, said Dr. Charles McMillan, the director of Los Alamos National Laboratory.

“Another area that I’d like to treat as an example is the security issues associated with our critical infrastructure,” McMillan said. “To just give you as sense of scale, in the time that it took me to say the last sentence my external firewalls at Los Alamos were challenged hundreds of times.” (Full Story)

Los Alamos National Laboratory announced that for the first time, irradiated uranium fuel has been recycled and reused for molybdenum-99 (Mo-99) production, with virtually no losses in Mo-99 yields or uranium recovery. This demonstrates the viability of the separation process, as well as the potential for environmentally- and cost-friendly fuel recycling. Medical isotope production technology has advanced significantly now that scientists have made key advances in separating Mo-99 from an irradiated, low-enriched uranium (LEU) solution.
