"Although the Greenland Ice Sheet initially speeds up each summer in its slow-motion race to the sea, the network of meltwater channels beneath the sheet is not necessarily forming the slushy racetrack that had been previously considered," said Matthew Hoffman, a Los Alamos National Laboratory scientist on the project.

Team advances understanding of the Greenland Ice Sheet’s meltwater channels

A high-profile paper appearing in Nature this week notes that observations of moulins (vertical conduits connecting water on top of the glacier down to the bed of the ice sheet) and boreholes in Greenland show that subglacial channels ameliorate the speedup caused by water delivery to the base of the ice sheet in the short term.

“By developing this ‘homo minutus,’ we are stepping beyond the need for animal or Petri dish testing: There are huge benefits in developing drug and toxicity analysis systems that can mimic the response of actual human organs,” said Rashi Iyer, a senior scientist at Los Alamos National Laboratory.

Los Alamos National Lab created its own system, the MagRay (Magnetic Resonance Imaging), that combines X-ray and MRI techniques to create 3-D images that reveal a liquid's proton content and density, which can tell you more about what it is. (Currently, most liquids scanners are slow and give a lot of false positives.) (full story)
LANL licenses polarization cryptography technique

Developed at Los Alamos National Laboratory, the technology has been licensed to Whitewood Encryption Systems Inc. for commercialization.
The LANL technology uses random polarization to generate random numbers for real-time encryption at high data rates. It represents an improvement over existing random-number generators based on mathematical formulas that can be broken by a computer with sufficient speed and power. (full story)
