Neutrino Trio Visits AAAS
On Sunday, February 15, an all-star team of neutrino scientists descended upon the

Annual Meeting of the American Association for the Advancement of Science in Seattle. And three of the five invited speakers came from Fermilab.

"There has been a lot of compelling evidence in the past half dozen years that neutrinos have mass," noted Fermilab's Boris Kayser, explaining why this is such an exciting time for neutrino physics.

Kayser set the stage with an introduction to the physics of neutrinos. Janet Conrad of Fermilab and Columbia University discussed current and future accelerator-based neutrino experiments. Rocky Kolb, from Fermilab and the University of Chicago, concluded the symposium by explaining the neutrino's role in astrophysics and cosmology.

Two other scientists described experiments with solar and atmospheric neutrinos.

The five scientists spoke to a crowd of 100-120 physicists, chemists, biologists, high-school teachers, journalists, and even a 12-year-old who asked a question of the presenters. "I had the sense that there was a lot of excitement in the room," Kayser said.

Scientists Say Administration Distorts Facts
By James Glanz
More than 60 influential scientists, including 20 Nobel laureates, issued a statement yesterday asserting that the Bush administration had systematically distorted scientific fact in the service of policy goals on the environment, health, biomedical research and nuclear weaponry at home and abroad.

The sweeping accusations were later discussed in a conference call organized by the Union of Concerned Scientists, an independent organization that focuses on technical issues and has often taken stands at odds with administration policy. On Wednesday, the organization also issued a 38-page report detailing its accusations.

NASA casts a shadow over bid to illuminate dark energy
By Geoff Brumfiel
NASA is delaying a mission to explore the fundamental make-up of the Universe, riling astronomers and physicists who consider it a top priority.

About three-quarters of all the mass and energy in the Universe may be dark energy. In a ground-breaking collaboration, NASA and the US Department of Energy (DOE) were set to explore this poorly understood entity on the Joint Dark Energy Mission, which supporters hoped would be launched into space by 2014 (see Nature 425, 887; 2003).

Engineers Week News
logo Next week activities will be in full swing for National Engineers Week 2004. On Monday, February 23 from 9:15 a.m. to 9:45 a.m., David Nevin, Head of FESS, will host the Engineers Week kickoff on the WH5E crossover. Don't forget to sign up for the Engineers Week Finale Luncheon by Wednesday, February 25. Send an email to e-week@fnal.gov to reserve your place for the luncheon. More information and a full schedule for Engineers Week can be found online.

Numbers From the Fermilab Library
The table below shows the top ten journals with articles that have received over 50 citations in SPIRES, giving results for articles published in 2003 and in 1993. Articles published 10 years ago had more time to gather citations, hence the 1993 numbers are higher than the 2003 numbers.
