Fermilab scientists, staff selected as APS fellows

Earlier this month, four Fermilab scientists were named fellows of the American Physical Society, a distinction awarded each year to no more than one-half of 1 percent of current APS members by their peers.

Gaston Gutierrez, Patty McBride and Rob Plunkett were named 2009 fellows to the Division of Particles and Fields. Craig Hogan was named a fellow to the Division of Astrophysics.

Gaston Gutierrez

Gutierrez, a scientist on the DZero experiment, was selected as a fellow for "leading the introduction of 'matrix-element' techniques for extracting precise measurements of standard-model parameters at hadron colliders and for seminal and vital contributions to the construction of the unique scintillating fiber tracker for the DZero experiment."

Patty McBride

McBride, currently deputy head of the Computing Division, was selected as a fellow for "original contributions to flavor physics at LEP and the Tevatron and to the development of major new initiatives in B-physics and collider physics."

Rob Plunkett

Plunkett, current co-spokesperson for Fermilab's MINOS experiment, was selected as a fellow for "distinguished contributions throughout the NuMI/MINOS Construction Project and subsequent leadership as co-spokesperson of the MINOS Experiment."

Craig Hogan

Hogan, head of the Center for Particle Astrophysics, was selected for his "innovative research in diverse areas of astrophysics, including the constituents of the universe, dark energy, gravitational waves, cosmological phase transitions, and cosmic background radiation."

Congratulations to all 2009 APS Fellows.


Bardeen, McBride elected AAAS Fellows

The American Association for the Advancement of Science has elected Fermilab employees Marge Bardeen and Patty McBride as AAAS fellows.

Bardeen and McBride were among 531 AAAS members nominated this year as fellows by their peers in recognition of distinguished contributions to their fields of study.

Marge Bardeen

Bardeen was selected to the AAAS Section on Education for "sustained, imaginative, and diverse contributions to the educational experience of K-12 teachers and students, including active engagement of teachers and students in research."

Patty McBride

McBride was elected to the AAAS Section on Physics for her "important contributions to particle physics experiments and for her leadership in the international scientific community."

Recognition of these new fellows will take place at the Fellows Forum on Feb. 20 during the AAAS meeting in San Diego.

At a mine's bottom, hints of dark matter

From New York Times, Dec. 18, 2009

An international team of physicists working in the bottom of an old iron mine in Minnesota said Thursday that they might have registered the first faint hints of a ghostly sea of subatomic particles known as dark matter long thought to permeate the cosmos.

The particles showed as two tiny pulses of heat deposited over the course of two years in chunks of germanium and silicon that had been cooled to a temperature near absolute zero. But, the scientists said, there was more than a 20 percent chance that the pulses were caused by fluctuations in the background radioactivity of their cavern, so the results were tantalizing, but not definitive.

Gordon Kane, a physicist from the University of Michigan, called the results "inconclusive, sadly," adding, "It seems likely it is dark matter detection, but no proof."

Coyotes key to keeping goose population in check

A male coyote at Eola and Batavia Roads on Dec. 28, 2006.

Coyotes and geese are among the most visible wildlife species on our site, and they have the potential to interact with humans in a regular and significant way that can have implications far beyond Fermilab.

The control of goose populations has become a growing issue in suburbs as a proliferation of detention and retention ponds has attracted larger, often year-round flocks.

A study on the relationship between coyote predation of geese and goose population control in urban areas was done in part at Fermilab by Justin Brown, of Max MacGraw Wildlife Foundation in Dundee, as his master's thesis at The Ohio State University. This look at the dynamics of urban populations of Canada geese and coyotes was conducted at Fermilab in 2004 and 2005 through the NERP program.

As recently as 1978, Fermilab imported Canada geese to the site. On the other hand, during the mid-1990s, coyote populations were depleted, owing primarily to an epidemic of sarcoptic mange.

Current estimates of Canada geese numbers are in the thousands, and coyotes now number between 15 and 20. Brown discovered that the primary means by which coyotes prey on geese is through hunting out their nests, which results in roughly 75 percent of all Canada goose egg mortality. There is also a strong suggestion that during the nesting season, coyotes may shift their territories somewhat to take advantage of goose nests.

Brown examined the question of whether this behavior has any real effect on the growth of the goose population. His model of goose population dynamics shows that the current net birth rate for geese is 1.055. However, if coyote predator behavior is statistically removed from the model, the birth rate jumps to 1.255. To put these numbers in perspective, the first population size would double in 13 years, but the second (without coyote intervention) would double in just 3.6 years.

The important lesson here is that species interact in ways that profoundly affect each other. Even though some people might not especially admire coyotes, or may actually fear them, they play an important and vital role in the overall functioning of the community.

-- Rod Walton, Fermilab ecologist

Employee Advisory Group nominations due today

Nominations for an employee advisory group forming at Fermilab are due today. The advisory group will provide Fermilab senior management with employee perspectives, concerns, insights and suggestions with regard to the development and implementation of new and revised policies that affect the Fermilab workplace. It is Fermilab's goal to establish and maintain a safe and productive workplace environment where employees can pursue the highest-quality work while maintaining a healthy work/life balance. Consider nominating yourself or a coworker for this important role.

Learn more about the Employee Advisory Group.
