Employees learn about their risk of osteoporosis |
|
| |
Yesterday, Melodee Probst, radiological technologist from Delnor Hospital, scanned Ruth DeJerld's heel with an ultrasound machine and broke the bad news: her bone density was a little below normal. Sandy Boyd, hospital outreach and screening specialist, discussed with DeJerld methods to maintain and promote bone health. DeJerld, of the Main Injector Recycler Office, was grateful for the screening. "Now I know I have a problem," said DeJerld. "I started taking calcium last week--I'll definitely continue." Appointments for yesterday's free screening filled quickly. Within two hours of inviting sign-ups, Fermilab's Medical Office reported all 43 spots taken. Due to the high demand, the Delnor group has agreed to return to Fermilab on November 28. Screenings will be held from 8:30 a.m. to noon. Employees will be able to make appointments through the ES&H website.
After a morning of screenings Boyd said, "We've definitely seen some people who need follow up." Bone loss can affect men and women of any age and any ethnicity. Women, ages 50 and older, of Asian, Caucasian and Hispanic descent are at the highest risk. About half of these women have low bone mass, according to the National Osteoporosis Foundation. In non-Hispanic African-American women this number is about 35 percent. Bone loss is preventable through diet, supplements and exercise. "It's easier to maintain healthy bones than it is to rebuild them," said Boyd. "Catching bone loss early will lead to fewer problems. We are encouraging patients to take the initiative in discussing this with their doctors."

| Particle Astrophysics Center discusses new leadership | |
| |
Members of Fermilab's Particle Astrophysics Center gathered yesterday to discuss the center's future and new leadership. "The center will play a prominent role in the future of Fermilab, and we are currently without a director," said Hugh Montgomery, Fermilab's associate director for research. Montgomery was referring to the fact that PAC founder Rocky Kolb retired from his position as director in September and has not yet been replaced. Kolb, now chair of the U.C. Department of Astronomy and Astrophysics, and Fermilab Director Pier Oddone have established a committee to search for a new director in a process that is expected to take about a year. Montgomery announced at the meeting that Fermilab physicist Scott Dodelson will serve as the interim director while the committee makes a selection, with a term stretching from December 1, 2006 to September 30, 2007.
After the announcement, Dodelson offered suggestions for the coming year, including the formation of committees to attract visitors, provide outreach, and chart the center's future. He noted some of the center's successes, and said he didn't want to impose too much "top-down" structure. "In the past things have just percolated here--and I think we want to maintain that," said Dodelson.

Science Magazine November, 2006: Japanese Latecomer Joins Race To Build a Hard X-ray Laser SAYO, HYOGO PREFECTURE, JAPAN--It's the scientific version of keeping up with the Joneses. Once researchers in one region plan a big, new experimental device, researchers everywhere want their own. The latest example: x-ray free-electron lasers (XFELs), which promise beams that are vastly brighter and with higher energy and shorter pulses than today's workhorse synchrotron x-rays. Read More |
| WZ couple: Discovering a match made in heavies | ||
| ||
|
The mediators of the weak interaction, the massive W and Z gauge bosons, are readily produced at the Tevatron and have been studied extensively by the CDF and DZero experiments. But producing pairs of heavy gauge bosons is far more rare. While one W boson is produced in every 3 million Tevatron collisions, and one Z boson in every 10 million, WZ pairs are produced only once per 20 billion events. Facing these odds, it is no wonder that WZ has never been observed--that is, until now.
The elusive WZ has finally been netted at CDF. We found it by searching for WZ production in its most easily observable signature, where 3 charged leptons are produced along with missing energy from a neutrino. CDF observed 16 of these signatures, and about 13 of them are expected to be WZ events. If WZ production was not actually happening in the Tevatron, the probability of getting this result would only be 2 in a billion. This indicates that our results are significant; and we have, in fact, observed WZ production. Finding the WZ pair is important because it teaches us about how gauge bosons interact with each other, and it confirms Standard Model predictions. Observing such a rare process at CDF also represents an important experimental milestone in our pursuit of the Higgs particle and new physics at the Tevatron. We look forward to a bright future as we continue to collect data from Run II!
