On Wednesday, Jan. 14, Fermilab scientists Joe Lykken and Don Lincoln will appear in the NOVA special "Big Bang Machine." The documentary will air at 9 p.m. Central time on WTTW (viewers should check their local listings). It will explore the deepest mysteries of the early universe and the quest to find the Higgs boson.

FermiWorks and retirement savings plans email

As you are aware, Fermilab is in the process of moving retirement savings plans to Fidelity. Over the weekend Fermilab completed multiple activities related to the retirement plan transition. As a result, employees received an open enrollment event via email from FermiWorks about retirement savings plans. You do not need to do anything in FermiWorks regarding your retirement savings plan at this time.

From now on, employees will make changes to their payroll deductions and investment elections on the Fidelity transition website. Remember: Jan. 14 is the pre-blackout period deadline for payroll deductions changes and Jan. 20 is the pre-blackout period deadline for investment elections. The blackout period begins on Jan. 23 and ends the week of Feb. 15. After Feb. 15 you will be able to view your retirement savings plans elections on the Fidelity transitions website, and you will be able to make changes to payroll deduction and investment elections at any time.

All employees will be notified via Fermilab Today when all retirement savings plan transition activities are completed. If you have any questions, contact the Benefits Office.

New calculations support dark-matter discovery by DAMA, say physicists

From Physics World, Jan. 12, 2015

A controversial claim by the DAMA group that it has detected dark matter in an underground lab in Italy might turn out to be true after all, according to physicists in Europe and the US. The new research reconciles the claimed detection with apparently null results from other experiments, as well as indirect astrophysical evidence. It proposes that dark matter interacts with ordinary matter not via one of the four known fundamental forces but instead through a fifth force mediated by an axion-like particle.

Transition edge sensors

This wiring diagram, drawn in 1994, is an early sketch of a concept that might help scientists detect dark matter or discover what happened just after the big bang. It was drawn by physicist Kent Irwin of Stanford University and SLAC National Accelerator Laboratory, about a year into his development of the transition edge sensor.

The TES makes use of a centuries-old concept in particle detection. The cooler a metal is, the better it is at conducting electricity. A particle that hits a metal will give itself away by producing heat and changing the metal's conductivity.

In the late 1800s, American astronomer Samuel Langley created a bolometer, a device that used delicately balanced metals to detect the smallest changes in heat. By 1880, it was sensitive enough to detect the thermal radiation from a cow standing in a field more than a quarter of a mile away. Today, technology based on Langley's bolometer is used in many experiments, including the Planck satellite, which studies patterns in light from the early universe.

Before the TES, scientists spent decades trying to figure out how to build bolometers out of superconducting metal. They did this because every superconductor has a temperature above which its ability to conduct electricity rapidly worsens. Right at this transition temperature, a superconducting metal becomes a superbly sensitive thermometer, making it ideal for use in a bolometer.

However, bolometers operating at this transition temperature also tend to become unstable.

Astronomers seek widest view ever of the universe with new telescope

From The Washington Post, Jan. 11, 2015

SEATTLE — At the annual meeting of the American Astronomical Society last week, the booth devoted to a revolutionary new telescope called the LSST got a lot of traffic.

Staffed by scientists from the University of Washington and other institutions, the display didn't feature sexy pictures of galaxies or nebulae, but it did include a sign that said LSST is hiring.
