The glorious boneyard: A report from our starting line

A friendly, athletic man from the Los Alamos National Laboratory in New Mexico, Giday WoldeGabriel is the team’s chief geologist: a connoisseur of the stacked volcanic tuffs that the bone prospectors employed to date their finds.
I asked him why, geologically speaking, this improbably discrete patch of the Rift was the Klondike of the fossil hominid world. It turned out to be complicated. A combination of biochemistry and tectonics. But WoldeGabriel circled back to the common ingredient in both life and death. (Full Story)
Los Alamos researchers help forecast how melting ice will affect sea levels
Stephen Price is also studying the effects of melting ice sheets on sea levels. From the New Mexican.
At a conference in Hobart, Tasmania, last month, Los Alamos National Laboratory climate scientist Phil Jones addressed one of the outstanding unknowns in global warming — the problem of projecting and quantifying how fast and how high sea levels will rise in the future. His presentation, representing the recent work of a team of researchers at the laboratory, focused on Greenland and Antarctica, and how quickly water that is locked up in ice sheets and glaciers might be released into the surrounding oceans.

LANL wants students’ glimpse of lab’s future
What kind of issues will scientists at Los Alamos National Laboratory be addressing 70 years from now? That’s a question lab officials are posing to sixth- through 12th-grade students in northern New Mexico in an online contest.
The Los Alamos STEM Challenge asks students to envision the next 70 years of discovery and create a poster, video, written essay or an idea for an application software that communicates what they foresee. (Full Story)
Online Competition Challenges Northern New Mexico Students
As part of Los Alamos National Laboratory's 70th anniversary of service to the nation, LANL is sponsoring an online science, technology, engineering and math (STEM) challenge for Northern New Mexico students in grades six through 12. LANL's STEM Challenge invites students to learn the history of the Laboratory and the work currently being performed and then design a poster, create a video, write an essay or design an app on their version of a LANL science or technology in the year 2083.

Los Alamos researchers and German collaborators have investigated the application of giga-electron volt energy proton beams for medical imaging in combination with proton radiation treatment for cancer.
The use of such a high-energy proton beam is ideal for imaging small tumors within patients for targeted proton therapy. Proton radiography, which was invented at Los Alamos, employs a high-energy proton beam to image the properties and behavior of materials. (Full Story)

Scientists studying data from the Curiosity rover have found another interesting puzzle, one which may easily have gone unnoticed were it not for one diligent researcher in particular, Nina Lanza of Los Alamos National Laboratory.
The ChemCam's laser is one of the most important tools Curiosity has to study the composition of Martian rocks. It vapourizes a tiny spot on a rock's surface, and the resulting sample can then be analyzed by the spectrometer. (Full Story)
Laser empties atoms from the inside out
An international team of plasma physicists has used one of the world's most powerful lasers to create highly unusual plasma composed of hollow atoms.
Lead author Dr James Colgan, from the Los Alamos National Laboratory, said: “The conditions under which the hollow atoms were produced were highly non-equilibrium and the production mechanism was quite surprising. (Full Story)

Seven months after it hurtled to a landing on Mars, NASA’s Curiosity rover has rolled just 738 metres across the surface. It remains about 10 kilometres from its primary goal: Aeolis Mons, a 5-kilometre-high mountain thought to contain layers formed in ancient ponds.
Since 23 January, the rover has more or less stayed in one place, a region called Yellowknife Bay. Yellowknife “has been a great place to start”, says team member Roger Wiens of Los Alamos National Laboratory in New Mexico. (Full Story)

In the worst case long-term scenarios, however, the Save the Redwods League projects that most habitat for coastal redwoods would eventually be rendered unsuitable for the big trees. In the near term, however, coastal redwoods may have an environmental advantage over their inland sequoia cousins since fog condensate provides as much as 45 percent of their annual water needs, says Park Williams, a climate and forest researcher at Los Alamos National Laboratory in New Mexico.

Game-changing career opportunities for postdocs are everywhere. Whether it is a paper to write, a fellowship to chase, or an informal conversation to have, any opportunity could be “the one” —how do you pick which avenues to pursue?
For any opportunity, Eric Brown, deputy group leader in the Physics Division of Los Alamos National Laboratory, advises weighing “the potential return on investment versus the time you would put in and whether you’ve done something that can achieve this goal in a different way.” (Full Story)

Astronomers conduct first remote reconnaissance of another solar system
Researchers have conducted a remote reconnaissance of a distant solar system. From Space Daily.
"The variation in the spectra of the four planets is really intriguing," said Didier Saumon, an astronomer at Los Alamos National Laboratory who was not involved in this study. "Perhaps this shouldn't be too surprising, given that the four gaseous planets of the solar system are all different. The hundreds of known exoplanets have forced us to broaden our thinking, and this new data keeps pushing that envelope." (Full Story)
