California scientists are reporting a pair of victories in the epic struggle between man and mosquito.
A team at the University of California, Riverside, appears to have finally figured out how bugs detect the insect repellent known as DEET. And the team used its discovery to identify several chemical compounds that promise to be safer and cheaper than DEET, according to the report in the journal Nature.

In 1818, the 21-year-old Mary Shelley published the great (perhaps greatest) classic of gothic literature, Frankenstein, Or the Modern Prometheus. As we all know, it's the story of a brilliant and anguished doctor who wants to use the cutting-edge science of his time — the relationship between electricity and muscular motion — to bring the dead back to life. Two decades before Shelley's novel, the Italian Luigi Galvani had shown that electric pulses could make dead muscles twitch.
Eye contact may prove persuasive only if a person's already on your side, a study finds.
Pop psychology holds that to connect with someone, you should look deep into their eyes. The more you look, the more persuasive you'll be. But that may work only when your audience already agrees with you.
Researchers in Germany tested the power of the eye lock by polling university students about their opinions on controversial issues like assisted suicide, nuclear energy and affirmative action in the workplace.
