And the record has been a good one, give or take a dozen or so non-threatening delivery-truck mishaps and a couple of misdirected deliveries; more than 7,000 loads have been carried there –
Since 2004, the sun has been in a prolonged period of low sunspot activity, which has led some to fear that the phenomenon could lead to global cooling, a new ice age, the death of the sun or even to the end of the world predicted by the Mayan calendar.
But the reality is that the phenomenon is part of a natural 11-year repeating sunspot cycle that fluctuates from intense activity to no activity and back again about every six years. And while it's interesting that the low number of sunspots over the past few years is the fourth longest such trend since the mid-1600s, it's by no means any reason to panic, said Geoff Reeves, a space scientist at Los Alamos National Laboratory.

Star crust is 10 billion times stronger than steelThe crust of a neutron star is strong enough to hold up ultra-dense mountains, a new simulation suggests. Penn State Illustration
Since laboratory experiments cannot replicate the extreme conditions on the surface of a neutron star, astronomers have largely assumed that the crust's strength would be similar to that of the strongest substances on Earth.
But in new computer simulations, Charles Horowitz of Indiana University and Kai Kadau of the Los Alamos National Laboratory show the crust of a neutron star is much stronger. Materials like rock and steel break because their crystals have gaps and other defects that link up to create cracks. But the enormous pressures in neutron stars squeeze out many of the imperfections. Test the stronger-than-steel story here.
Mapping the evolution of ideasComparing physics maps from 1997 and 2006, above, shows how areas shrink and grow and how they merge with one another. Physics World image.
Now physicists have made a map using the Physics and Astronomy Classification Scheme (PACS) codes produced by the American Institute of Physics (AIP). Taking papers from the last two decades in the AIP's database, Mark Herrera from the University of Maryland, David Roberts from Los Alamos National Laboratory and Natali Gulbachce from the Northeastern University in Boston, have created a map using the links between different PACS numbers.

Chu visits Los Alamos National Laboratory
LOS ALAMOS, N.M. (AP) -- He's the U.S. energy secretary and the new boss, but Steven Chu was all scientist as he launched a two-day visit to New Mexico with a stop at Los Alamos National Laboratory. Chu chatted informally with lab scientists about their ongoing research into climate modeling, hydrogen storage, nanotechnology, HIV and other issues on Thursday. In a large hall in the lab's computing center, he scrutinized displays of the programs, listened intently to explanations, then peppered lab employees with questions that made it clear he was a fellow scientist.
"He knew a lot about our field - which was dazzling," said Bette Korber, a theoretical biologist who is researching HIV. (Extra! Extra! Read all about it
Energy secretary assessing labs
LOS ALAMOS, N.M. (KRQE) - Energy Secretary Steven Chu toured Los Alamos National Laboratory Thursday and is scheduled to visit Sandia National Laboratories on Friday.
His department oversees both facilities. After working in Washington Chu jetted across the country and at 5 p.m. was hustled into LANL for a whirlwind three-hour tour.
The Los Alamos agenda showed Chu the lab does a lot more than just weapons work, for example using computers in the war on HIV/AIDS. (Enjoy the story on your own computer!)
Energy secretary visits Los AlamosALBUQUERQUE, N.M. (AJ) -- The visit was an opportunity for Los Alamos to display what a few of its 2,200 some Ph.D.'s have been up to, with large posters specially made for the visit describing research in fields as diverse as climate change and cybersecurity.
“We wanted to give him a chance to see the breadth” of LANL's work, said Terry Wallace, a principal associate director. (Subscription required to read this story.)
