Study Explains Acceleration of Greenland’s Inland Ice

AGU News:
WASHINGTON, D.C. — Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, a new study finds.
During the last decade, researchers have captured compelling evidence of accelerating ice flow at terminal regions, or “snouts,” of Greenland glaciers as they flow into the ocean along the western coast. Now, the new research shows that the interior regions are also flowing much faster than they were in the winter of 2000-2001, and the study authors propose a reason for the Read More

WASHINGTON, D.C. – The National Nuclear Security Administration (NNSA) last week conducted an International Radiological Assistance Program Training for Emergency Response (I-RAPTER) training in Almaty, Kazakhstan.
The training, held at the Institute of Nuclear Physics in Almaty, included using radiation detection equipment to locate hidden radioactive sources during a practical exercise. At the conclusion of the course, international first responders were able to appropriately Read More

New, Stricter Pajarito Road Access Rules Go Into Effect Aug. 12
- No more “vouching” for family members
Los Alamos National Laboratory, at the direction of the National Nuclear Security Administration’s Los Alamos Field Office, will restrict access on Pajarito Road to only Laboratory badge holders effective Monday, Aug. 12.
This means that Laboratory personnel and subcontractors will no longer be able to “vouch” for non-Laboratory personnel such as family members.
“Our Laboratory and security access procedures are continually reviewed and updated Read More

Enabling Time Travel for the Scholarly Web
- Banishing the dreaded Internet search where 30 percent of research paper hyperlinks fail to connect
An international team of information scientists has begun a two-year study to investigate how web links in scientific and other academic articles fail to lead to the resources being referenced.
This is the focus of the Hiberlink project in Read More

SFI News:
Glenn Loury of the Brown University Department of Economics will present “A Theory of Collective Reputations with Endogenous Identity’ at the next Santa Fe Institute (SFI) Colloquium at 3:30 p.m. Thursday, July 18 in the Noyce Conference Room at SFI. The event is free and open to all.
In his abstract, Loury writes:
“We explore a formal economic model of “collective reputations” — i.e., of the rational formation by external observers of beliefs about the unobserved traits of varied population aggregates. This phenomenon (sometimes referred Read More

AGU News:
WASHINGTON, D.C.—By pinpointing locations on Earth from space, GPS systems have long shown drivers the shortest route home and guided airline pilots across oceans. Now, by figuring out how messed up GPS satellite signals get when bouncing around in a storm, researchers have found a way to do something completely different with GPS: measure and map the Read More
