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 Washington DC 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 Hawaiiís 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.

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."
