Program finds lost genes in nematode genome

This is *C. elegans*. Its genome was thought to have been completed until a WUSTL computer scientist found otherwise.A computer scientist at Washington University in St. Louis has applied software that he has developed to the genome of a worm and has found 150 genes that were missed by previous genome analysis methods. Moreover, using the software, he and his colleagues have developed predictions for the existence of a whopping 1,119 more genes.

Despite hurdles, human missions to Mars are in the works

Mars Exploration Rover mission scientists remind us that the amazing success of the rovers *Spirit* and *Opportunity* is a harbinger for the day when humans inhabit the Red Planet.The major drawback to a human mission to Mars is preparing for the one to two years of radiation and microgravity exposure that astronauts must endure. While that is a large hurdle, enabling technologies are emerging that should be able to make this goal a reality over the next couple of decades, and America should go for it. That’s the theme of a report from NASA’s 2002 Astrobiology Academy appearing soon as a paper in Acta Astronautica.

Map of life on Earth could be used on Mars

Carinne Blank has a method she uses to date ancient life forms that could be helpful for specimens from Mars.A geologist from Washington University in St. Louis is developing new techniques to render a more coherent story of how primitive life arose and diverged on Earth – with implications for Mars.

Certain female fish have special mating preference

Male Bahamas mosquitofish (left) chasing a female (right).A biologist at Washington University in St. Louis has shown that for some fish species, females prefer males with larger sexual organs, and actually choose them for mating. That does not exclude males with an average-sized sex organ, called a gonopodium. These fish out-compete the larger-endowed males in a predator-laden environment because they have a faster burst speed than the males with larger genitalia, thus avoiding predators and staying in the mating game.

Kingsbury Ensemble to conclude season May 15

Washington University’s Kingsbury Ensemble will conclude its 2004-05 season with works of Antonio Vivaldi (1678-1741) and Johann Sebastian Bach (1685-1750) — today’s most popular composers of the Baroque era. The performance begins at 7:30 p.m. Saturday, May 15, in Holmes Lounge, Ridgley Hall. Tickets are $5 to $15.

WUSM gets grant for work on microscopic capsules

The National Heart, Lung, and Blood Institute has chosen the School of Medicine as one of four national research centers dedicated to the advancement of nanotechnology. The center, funded by a five-year, $12.5 grant, will be headed by WUSM chemist Karen Wooley. Read more in the following St. Louis Post-Dispatch article.
