Mitchell Lardner didn't pay much attention to an April 8 company memo alerting him and other employees of Sumitomo Corp. of America that they could be the targets of "home protests" from animal rights activists who believe the firm has ties to animal research. This won't affect him, Lardner reasoned. He's just a mid-level manager, and he believed it when his company said it had no such links.

Scientists in St. Louis have created a genetically altered strain of mousepox virus that is so potent it kills mice vaccinated against the mouse disease, rekindling concerns that some avenues of biotechnology research may be generating lethal knowledge useful to bioterrorists. Health officials emphasized that the federally financed work posed no threat to people.

For a century, the towering Tyrannosaurus Rex has been regarded as a savage killer marauding unchallenged across the later dinosaur era. But new research suggests a different interpretation, casting T. Rex as little more than a scavenger, stealing the kills of other carnivores. Paleontologist Jack Horner says the monster's forelegs were too short, its eyes too small and its speed too slow to make it a hunter.

Mice implanted with ovaries from much younger mice live to a riper old age, according to UC Davis researchers. Ovaries from female mice aged 11 months (the equivalent, in mouse age, to a 50-year-old woman) were replaced by fresh ones from 2-month-old females. The mice lived 40% longer than mice that had undergone no surgery, the scientists found.

Researchers from Columbia University have devised a technique to procure pure DNA from the dung of animals, which eliminates the need to capture, sedate and draw blood from wild, endangered or aggressive animals.

Fruit flies have the rudiments of consciousness, according to a study published online in the journal Nature Neuroscience. Bruno van Swinderen and Ralph Greenspan of the Neurosciences Institute in San Diego presented flies with various images. The flies responded with a characteristic burst of brain activity.

A university livestock program has stopped selling former research pigs to market after the announcement of a federal investigation into whether the animals had been genetically modified. The University of Illinois at Urbana-Champaign took the step after the Food and Drug Administration said more than 300 pigs sold to market should have been destroyed instead. The research involved increasing pigs' natural levels of some growth proteins already present in meat.

Bugs don't have lungs, so how do they breathe? Maybe more efficiently than people, according to the first close-up view of insects forcing air in and out of tiny oxygen pipes. It took one of the world's strongest X-ray beams -- a view hundreds of times more detailed than today's most sophisticated medical scans can provide -- for scientists at the Field Museum in Chicago and Argonne National Laboratory to videotape how beetles, crickets and ants breathe.

The European Parliament approved a ban on using animals to test cosmetics in the European Union by 2009. The 626-member parliament passed the final draft with a show of hands, ending years of debate. The ban will be implemented in phases as a compromise with cosmetics firms, who had said they needed time to find alternative test methods. Where no alternatives have yet been found, in three particular toxicity test areas, a ban will be phased in by 2013.

In the eternal war between the sexes, the lady side-blotched lizard wins it all: She selects her many mates, decides where they'll live and even determines if they will have sons or daughters. Virtually every element of the mating and reproductive cycle of the small American lizard is controlled by choices made by the female, according to UCLA biologist Ryan Calsbeek.
