<jats:p> Highlights from <jats:italic>Science</jats:italic> 's online daily news site, <jats:italic>Science</jats:italic> NOW, this week include a breathalyzer for cancer, the reason "close talkers" make others uncomfortable, ancient armored mammals at bat, and the effects of global warming on marine food webs. </jats:p>

<jats:p>In just 4 months, a research team in northern Laos captured an astounding 38 large-antlered muntjacs—a rare deer that was discovered only in 1994 and was photographed for the first time by a camera trap in 2007.</jats:p>

<jats:p>At an emergency meeting in Vientiane last month, researchers hammered out a set of measures that, if implemented within the next year, could give the saola, a rare ungulate no scientist has ever glimpsed in the wild, a shot at survival.</jats:p>
