Well, now we've seen it all: Scientists from UC Davis and San Diego State University have released a video of a venomous rattlesnake attacking a robotic squirrel. And we thought robojelly, the robotic jellyfish was weird. The video was made by Rulon Clark , a biology professor at San Diego State who is trying to determine how squirrels and rattlesnakes communicate in the wild. When a squirrel thinks a rattlesnake is nearby, rather than running away, it will raise its tail, heat it up, and wag it. Scientists call this "flagging behavior.

A recent Times article cites a study that implicates certain landscape trees as a significant source of hydrocarbons; and, hence, air pollution. One such popular tree, the liquidambar, was said to be a prime offender. No mention was made, however, that this particular tree is deciduous so that for the considerable period it is dormant (leafless), it emits no hydrocarbons. More important, deciduous trees, when strategically located near dwellings, provide shade during the summer and allow for passive heating by the sun in the winter.

Health news to keep in mind as a particularly cold winter wends on: Crackling logs in a fireplace might warm the heart and the toes. A toasty fire might even be good for the soul. But a new study in Chemical Research in Toxicology , a journal of the American Chemical Society, reminds readers that wood smoke is not particularly good for human bodies. Danish researchers showed that tiny particles from wood smoke damaged the DNA in human cells in culture.   Another study, published Monday in the Archives of Pediatrics and Adolescent Medicine , found that smoke from burning heating coal has negative health effects as well.
