When astronauts finally land on Mars, a safe bet is that they'll head for northern climes if they intend to spend much time there. That's because nearly all the available water is frozen as ice at the north pole.

Scientists at the California Institute of Technology and Purdue
University have determined the fine-detail structure of the virus
that causes dengue fever. This advance could lead to newer and more
focused strategies for devising a vaccine to protect the world
against a viral illness that causes 20,000 deaths each year.
Reporting in the March 8 issue of the journal Cell, Caltech
biology professor James H. Strauss, lead author Richard J. Kuhn of
Purdue (a former postdoctoral scholar in Strauss's lab), and
Michael G. Rossman and Timothy S. Baker, both of Purdue, describe

In an age when nearly all astronomical work requires really big telescopes, David Charbonneau is something of an anomaly.

Using specially prepared HIV-derived viruses stripped of their disease-causing potential, California Institute of Technology biologist David Baltimore and his team have invented a new method of introducing foreign DNA into animals that could have wide-ranging applications in biotechnology and experimental biology.
The Baltimore team reports, on today's Science Express Web site, on their study of single-cell mouse embryos that have been virally infected in a manner that leaves a new gene from a jellyfish permanently deposited into their genomes.

Astronomers using NASA's Hubble Space Telescope have made the first direct detection of the atmosphere of a planet orbiting a star outside our solar system and have obtained the first information about its chemical composition.

Scientists at the California Institute of Technology have discovered that hearing can significantly change visual perception, and that the influence of hearing on visual perception occurs at an early perceptual level rather than at a higher cognitive level.
Ladan Shams, a Caltech postdoctoral researcher, and Shinsuke Shimojo, a professor of computation and neural systems at Caltech report that visual signals are influenced significantly by sounds at early cortical levels that have been believed to be "vision specific."

Astrophysicists have combined the Palomar Mountain 200-inch Hale Telescope with the abilities of a new NASA satellite to detect and characterize a gamma-ray burst lying at a distance of only 5 billion light-years from Earth. This is the closest gamma-ray burst ever studied by optical telescopes.
