Study Finds Smoking in Movies Tied to Adolescent Tobacco Use

According to a new study, when it comes to smoking, adolescents may be emulating the movie stars they see on the big screen. Writing in the December 15 issue of the British Medical Journal, researchers at Dartmouth College report that they have found a link between tobacco use in movies and smoking amongst young people.

James D. Sargent and colleagues questioned 4,919 New England middle school students between the ages of nine and 15 about their smoking habits and movies they had seen. “For

Warming May Increase Risk Of Sudden Climate Change

Most climate change research has focused on gradual changes, such as the processes by which emissions of greenhouse gases lead to warming of the planet.
But new evidence shows that periods of gradual change in Earth’s past were punctuated by episodes of abrupt change, including temperature changes of about 10 degrees Celsius, or 18 degrees Fahrenheit, in only a decade in some places.

Severe floods and droughts also marked periods of abrupt change.

Just-For-Fun Experiment Creates Self-Assembly Method

An experiment that University of Chicago physicists conducted just for fun has unexpectedly led them to a new technique for producing nanoscale structures.
The Chicago physicists have built simple electronic devices using the new technique, which precisely controls the growth of metal wires along tiny scaffolds that automatically assemble themselves following nature’s own tendencies.

“This is perhaps the first time that it has been possible to assemble large numbers of parallel, contin

Cluttered Surfaces Baffle Echolocating Bats

When it comes to locating a meal, insect-eating bats generally employ one of two foraging tactics: capturing prey in the air or snatching it from a substrate. Accordingly, the animals use different kinds of echolocation during these activities. Whereas aerial hunters tend toward longer calls with constant frequency, substrate-gleaning species generate short calls that sweep from low to high frequencies (FM echolocation). Less clear, however, is how effective the latter is at distinguishing the prey i

Gentech breakthough for ecological Chrysanthemums

Researchers at Plant Research International in the Netherlands have achieved a breakthrough in the development of chrysanthemums with resistance to thrips, bringing the ecological cultivation of chrysanthemums a step closer. This is the conclusion of the thesis with which Seetharam Annadana, a Plant Research International guest member of staff from India, recently obtained his doctorate at Wageningen University. Annadana developed new techniques which make possible the genetic modification of two th

American Geophysical Society Meeting, San Francisco, December 2001

Pressure system secrets could help long range forecasts.

The rise in levels of greenhouse gases has halted an oscillation of air pressures over the Arctic, bringing warmer, wetter winters to Northern Europe, Siberia and Alaska. The shift could get worse with increasing CO2 emissions, delegates heard this week at the American Geophysical Union meeting in San Francisco, California.

The trend is unlikel
