URA Runs Science Ads in The Washington Post to Influence Policy Makers|
Promoting research in basic science, six advertisements will appear in
The Washington Post in May and early June. The first set of ads
ran in The Washington Post last week, and the second set appears
in the paper this week. Through the combined efforts
of Universities Research Association, Inc., Research! America and The
Science Coalition, the ads seek to educate policy makers on the importance
of funding basic science, even when government resources are scarce.

Recent Butterfly Sightings at Fermilab|

Fermilab engineer and butterfly expert Tom Peterson reports a recent sighting
of a Luna moth on Fermilab's site. "Something great is that people have started
to call me when they see something like this Luna moth or the
Meadow Fritillaries," Peterson said. "The first two butterfly/moth highlights
of the year were by other people." In his report, Peterson writes
that Bill Griffing and Tim Miller of ES&H spotted the Luna moth
along the path between the Lederman Education Center and Wilson Hall.
Peterson found three Luna moths later that same evening.
Luna moths are members of the Giant Silk Moth family (Saturniidae).
They feed as caterpillars on walnut and other trees and overwinter
in a cocoon on the ground. Like other giant silk moths,
they do not feed as adults and live for approximately a week.
They rest during the day, usually well-hidden in the green vegetation,
fly at night, and are quite attracted to lights.

Asteroids Change Colour With Age
In an article published today in the journal Nature, a team led by Robert Jedicke of the University of Hawaii’s Institute for Astronomy provides convincing evidence that asteroids change color as they age.
David Nesvorny, a team member from the Southwest Research Institute in Boulder, CO, used a variety of methods to estimate asteroid ages that range from 6 million up to 3 billion years. Accurate color measurements for over 100,000 asteroids were obtained by the Sloan Digital Sky Survey (SDSS), and catalogued by team members Zeljko Ivezic from the University of Washington and Mario Juric from Princeton University.
Electrical Safety Month Profiles|
In connection with Electrical Safety Month, Fermilab Today offers a series of profiles recognizing Electrical Safety Managers at Fermilab.
Electrical Safety Manager Jack MacNerland
As the Feynman Computing Center's Building Manager and as electrical
coordinator, construction coordinator and a task manager for the
Computing Division, Jack MacNerland juggles many different tasks
every day. In everything he does, however, safety is always a priority.
"We try to maintain the same safety procedures throughout our system,"
said MacNerland, who is also a member of the lab's safety committee.
"I want our employees to go home exactly the way they came here in
the morning. It's not so important that tasks get done quickly, but
that they are done well and safely."
As the FCC's first building manager, MacNerland was responsible for
adapting the laboratory's safety procedures for use in the CD. With
the amount of computing power continually increasing, he now faces
the challenge of adapting an older building to current requirements.
Air conditioning, power supplies and electrical conduits all require
upgrades and maintenance to keep the FCC in good working order,
necessitating many hours of work by electricians and contractors.
"We make sure everyone carries a non-invasive electric tester to
make sure electrical circuits are off when they should be," explained
MacNerland. "They also use a voltmeter to double-check within the panel
that nothing is live."
