Newly observed high-altitude auroras surprise scientists
December 11, 2003 (USA Today)
A military satellite has detected auroras, those shimmering displays of colorful light, at altitudes far higher above Earth than previously known, confirming anecdotal reports from astronauts that scientists had dismissed.

UCSD scientist keeps eye on sun
December 11, 2003 (San Diego Union-Tribune)
For the first time, scientists are creating three-dimensional images
of huge clouds of plasma that the sun periodically hurls into space.
Strange Lights Imaged, Astronauts Not Crazy
December 10, 2003 (Space.com)
The first direct images ever made of a solar storm as it engulfs Earth have also vindicated astronauts who said they'd seen colorful sky lights at dubiously high altitudes.
Smoky air samples yield valuable data
November 28, 2003 (San Diego Union-Tribune)
On Oct. 26, as smoke and ash rained on San Diego County from the wildfires, a small team of UCSD scientists began collecting samples of acrid air outside a fifth-floor laboratory on campus.
Smart-dust designers deliver dirt-cheap chips
November 27, 2003 (EDN.com)
Imagine fully functional sensor circuits so small and inexpensive that you could afford to scatter thousands into an area of interest to sense local conditions or to detect the presence and movement of chemicals, vehicles, or even humans. These small circuits, collectively referred to as smart dust, are part of a new vision of tiny elements that combine sensing, computing, and communications. Although today's technology has not yet reached dust-particle size, several design teams, including the military, are working hard to perfect the concept and decrease the size. Some of their long-term dreams include intravenous circuits that seek out and attack cancer cells and networked sensors that are dropped from an airplane and then report troop and vehicle locations in a battlefield situation.
Why not rocket science?
November 20, 2003 (The Oregonian)
Sally Ride flew into space two years before Ashlen Saulson was born. But the 18-year-old senior at St. Mary's Academy says although the former astronaut may be from another generation, she "definitely" serves as an important role model for girls interested in science and math.
Antihydrogen atoms may have been drifters
November 1, 2003 (New Seiences)
IT IS a mystery of cosmic proportions: why is the universe filled with matter and not antimatter? Physicists hoping to find the answer have been left scratching their heads this week by an analysis which claims that some antihydrogen atoms created last year may not be normal antiatoms after all. Instead they may sit on the blurry line between atoms and plasma.
