A model to explain how animals fly
In order to control themselves, flying creatures need to use specialized movements, or maneuvers, to get from one place to another. For a long time, researchers have wondered exactly how they do it. Now, researcher Tyson Hedrick and colleagues have created a model of flight for small creatures (like insects) and large ones (like birds) to better explain how it's done.

Teens ask: Will the stimulus act work?
This year's Moody's Mega Math Challenge problem, "$787 Billion: Will the Stimulus Act Stimulate the US Economy?" asked high school students to identify and mathematically assess the parts of the stimulus package most likely to produce the greatest improvements in employment and the time frame over which this effect would take place. Top 23 teams are announced.

Robots working in the laboratory
Could robots replace scientists in the laboratory one day? Some researchers seem to think so -- at least to some degree. After building a robot that designed and performed scientific experiments in a laboratory, Ross King and colleagues seem convinced that robots will work together with human scientists someday in the lab. But, they do not believe human scientists will be replaced entirely.

Boy or girl? Female finches make the choice
In some species, females can adjust the sex of their offspring when they are pregnant. Depending on the quality of their mate, females can sometimes decide if they will have a male or a female baby. This is a very adaptive trait that allows the females to make the most out of what they have -- their offspring, their mates, and food.
