HOUSTON - Designing groundbreaking experiments and being
accepted into an elite program alone would have most students
floating on air. But after working for months to perfect their
ideas, two teams of University of Arizona students are at NASA's
Johnson Space Center this week to literally g…

children around a lab setting, but so far, it's been pretty
In a situation reminiscent of Spider-Man, a team led by UA
researchers has discovered sweet-potato whiteflies - a common crop
pest - experience "instant" evolution when infected with Rickettsia
bacteria, which allows them to thrive better than uninfected
A group that includes a University of Arizona astronomer has
discovered a galaxy believed to have formed just after the Big
Bang. With stars dating back 13.5 billion years, the galaxy - which
hasn't been named - was created only 200 million years after the
Big Bang, astronomers believe, and …

Mars' current atmosphere thanks to a dry-ice discovery.
Solar power and wind energy are popular in the green movement,
but when there's no wind or sun, there's no power.

It's still unknown who wrote it and what it means, but a UA-led
team has solved one mystery of the "Voynich manuscript" - its age.
Through radiocarbon dating, a team led by University of Arizona

island's largest cities, officials are slowly beginning to consider
rebuilding metropolitan areas.
Turns out some moths are good for more than hogging the
lamplight or putting holes in your favorite sweaters. They may help
scientists answer an important mystery in evolutionary biology: How
do organisms decide to use their limited resources?
Peter Rose sees the science around him at Biosphere 2. But to
Rose, science also is art.
Scientists and rock stars usually don't have much to do with
each other - unless you're Eric Reiman. The University of Arizona
psychiatry professor is part of a six-page ad dedicated to "Rock
Stars of Science" in this month's issue of GQ magazine.
The Internet lets us watch television shows, connect with
friends and even have groceries delivered if we don't want to brave
the store. It's used for just about everything - but that doesn't
mean it's perfect.
The Large Synoptic Survey Telescope is an impressive astronomy
project that will allow scientists to conduct sophisticated
research with cutting-edge data.
If you think Wikipedia can't be scientifically analyzed, look no
further than Sudha Ram.
Dave Newman e-mailed a village in Ghana last week to offer
advice about water pumps.
Joshua Lopez gently peels transparent covering from a metal tray
in his lab. His actions are fluid, like he's undoing gift-wrap he
plans to reuse. He has good reason to be careful: Inside the
plastic bundle is a human head.
William K. Hartmann sees the big picture. Talk to him about his
varied interests - Spanish conquistadors, space artist Chesley
Bonestell, archaeology, the environment - and you'll see.
University of Arizona astronomer Laird Close understands the
value of double-checking your work.
In one room, Essy Levy hands out small glass vials and colorful
posters about biotechnology as she explains the importance of
A group that includes a local researcher is one step closer to understanding how cancer cells work. The group studied 200 breast-cancer-tissue samples provided by Nhan Tran, a UA graduate and associate investigator at the Translational Genomics Research Institute.
If you're depressed, your internal wiring may not be the only
culprit. Local research suggests it might be more than biology.
During the time of year when students' brains are shutting off,
Tricia Hindley is busy learning how they work.
