Larger male genitalia in some fish are more attractive to females, but they make the males more susceptible to predation, Yale researchers reported Friday in the Proceedings of the National Academy of Sciences. Studying western and Bahamas mosquitofish -- species in which the males cannot retract their gonopodia -- the team found that females preferred to watch videos of males with digitally enhanced genitalia.

Scientists have discovered a trove of life-forms lurking in the human gut -- 395 different bacteria, 60% of which had never been described, according to a report published Thursday in the online edition of the journal Science. The study analyzed samples of stool and mucous from six parts of people's colons. The results were surprising and "a bit sobering," said the paper's lead author, Stanford University researcher Dr. Paul Eckburg.

Pictures of products danced in his head. There was an Apple iPod, then a black Aeron chair. A coffeepot by Capresso and a washing machine by Dyson. Christian Dior followed by Versace, Oakley, Honda, Evian and Louis Vuitton. Each icon of commercial design -- 140 in all -- was projected onto goggles covering the eyes of a 54-year-old, college-educated, middle-class white male.

Despite the midnight hour, Jim Kohn decided to top off a night at the opera with a visit to a museum. So -- decked out in a tuxedo -- the 41-year-old Los Angeles man very early Sunday caught the last act of the California Science Center's "Body Worlds: The Anatomical Exhibition of Real Human Bodies." Drawing more than 650,000 spectators since it opened in July, the collection of "plastinated" cadavers proved so popular that museum officials kept the doors open for the final 41 hours.

"We are in great haste to construct a magnetic telegraph from Maine to Texas," Henry David Thoreau wrote in "Walden," which was first published 150 years ago. "But Maine and Texas, it may be, have nothing important to communicate." Thoreau would be astonished at just how much information we have to communicate a century and a half later. How much of it is actually important remains a question.

Spiders, it turns out, are very much like geckos -- at least in the way in which they cling to walls and ceilings. In both cases, the creature's extraordinary gripping ability has been found to be produced by Van der Waals' forces generated by literally thousands of microscopic hairs on each of their feet. The discovery provides a remarkable example of evolution providing identical answers to the same problem in widely divergent species.

Pear-shaped people may have more trouble losing weight -- from their hips, thighs and posterior, specifically -- but it's the apple-shaped folks who need to redouble their efforts. Their fat is more dangerous. Researchers have known that carrying extra pounds around the belly and upper body increases the risk of hypertension, heart disease, stroke, diabetes and cancers of the breast, ovary and prostate. Now they're learning why.

When Dr. Darlyne Johnson, 46, found out three years ago that she needed hernia surgery, she balked. "I knew what was going to happen -- I'd get sick." Each time Johnson has had surgery over the years, she's wound up with such terrible nausea and vomiting from painkillers that she had to stay in the hospital overnight. This time, however, she heard about a device called ON-Q.
