| Volunteers needed for annual prairie seed harvest | ||
| ||
|
Volunteers are needed to help maintain prairie diversity by collecting seeds at the annual seed harvests Saturday, October 7 and Saturday, November 4.
"Everyone is welcomed to help. You don't have to be a botanist," said Bob Lootens of Roads and Grounds. "If we need rattlesnake master [yucca-like plant], we'll show you how to find rattlesnake master."
Less than one tenth of one percent of the Illinois prairie remains in its complete and original state. Most prairies lack many of their original species and ecological interactions, such as insect pollination. Fermilab has been working since the mid-70s to reverse this process. "We've come a long, long way," said Martin Valenzuela, senior grounds keeper. During seed harvests volunteers collect seeds from older, species-rich areas for a spring-time planting in younger prairies. This fall, volunteers will collect uncommon species like white and purple prairie clovers, pale purple cone flower, yellowish and bottle gentians. Volunteers should wear field clothing and gloves, and bring paper grocery bags and hand clippers if possible. Work will start at 10 a.m. and will last until 2 p.m. The harvests will take place in the center of the Tevatron ring, signs will be posted and a picnic lunch will be provided. E-mail Bob Lootens if you plan to bring a large group.
Call Fermilab switchboard at (630) 840-3000 in case of bad weather. For more information call the Public Affairs Office at (630) 840-3351 or check this Website.

PhysOrg.com, September 18, 2006: Scientists snap first images of brown dwarf in planetary system Scientists using NASA's Spitzer Space Telescope have discovered and directly imaged a small brown dwarf star, 50 times the mass of Jupiter, orbiting with a planet around a Sun-like star. Such an arrangement has never before been seen but might be common, the scientists say, leading to solar systems with distorted planetary orbits. Kevin Luhman of Penn State University is the lead author on a report describing this discovery, which will be published in The Astrophysical Journal. The discovery concerns a class of the coldest brown dwarfs, called T dwarfs. "Over the last ten years, astronomers have been extremely successful in finding planets close to their host stars using indirect detection methods," said Luhman, an assistant professor in the Penn State Department of Astronomy and Astrophysics. "Because of its infrared capabilities, Spitzer is well suited for directly detecting cool T dwarfs, and perhaps even large planets, in the outer parts of planetary systems."
Luhman's team also discovered a second brown dwarf that is smaller yet, about 20 times the mass of Jupiter, orbiting another star. This smaller object could be the youngest T dwarf known, offering scientists a snapshot of early brown-dwarf development. The two T dwarfs are the first to be imaged by Spitzer. Shortly after these companions were found, Spitzer also discovered a T dwarf that is floating through space by itelf rather than orbiting a star. The team that discovered that T dwarf is led by Daniel Stern at NASA's Jet Propulsion Laboratory.

| Our Ambassadors | ||
We now have some 30 volunteers who will become new ambassadors from Fermilab
Fermilab's Community Envoy Program is designed to vastly enlarge our channels of communication with Fermilab's stakeholders. By establishing an ongoing dialogue between Fermilab's envoys and key stakeholders we are ensuring that community members have a regular point of contact for any information or concern related to Fermilab. Elected officials, city mayors, heads of civic and social organizations, homeowners' associations, local school officials, local area universities and local business leaders and organizations will have an established personal connection with a member of Fermilab who can help them understand the laboratory, its programs, and the impact that these programs have now or might have in the future on the local area. Our ambitions for a strong and healthy future will mean significant changes not only for Fermilab but for the community. As one of the members of our community task force said last year: "Fermilab has to think of itself as an integral part of the community, not an entity apart." Fermilab together with the community will confront the future challenges and opportunities. The envoys are a key ingredient in binding Fermilab and the community together. I want to personally thank our envoys - another example of the spirit that makes Fermilab a great institution. |
