In 2006, Timothy Carter, an Assistant Professor of Biology in the Ball State Department of Biology, was honored by the Wildlife Habitat Council for his work with the endangered Indiana bat population.

On Tuesday, 2 October at the E.B. and Bertha Ball Center at 6:30 p.m. he will give a talk: "Indiana Bats: Creatures of the Night." The event announcement reads: "Learn about Indiana's bats and what you can do to promote bats in your neighborhood while keeping them out of your house! At the end of the talk, we will go outside to watch and listen to bats as they feed around the Ball Center. Bring a flashlight!" There is no charge for this event but reservations are required (call 285-8975).

From the archives: Wireless printing at University Libraries

Just a reminder of a service now offered by the University Libraries that I announced in a previous entry: You can print from your laptop to select printers in the University Libraries- such as the Science-Health Science Library.

This means that you can sit in the "rotunda" on the first floor of Cooper and print downstairs to the Science-Health Science Library or by the Frog Baby Fountain and print to the Architecture Library.

How do you do this? Read the previous SHSL Blog post.

Secondhand smoke/Environmental tobacco smoke

Researchers from Stanford published a study in the May 2007 issue of Journal of the Air and Waste Management Association which measured outdoor tobacco smoke (OTS). They concluded that “it is possible for OTS to present a nuisance or hazard under certain conditions of wind and smoker proximity”(Klepeis, 522). If upwind from an active cigarette source or at least 2 meters away, OTS levels measured nearly zero. While OTS concentration levels can rival those of indoor levels when measured within 0.5 meters of an active OTS source, “unlike indoor SHS [secondhand smoke] levels, which decay slowly over a period of hours, OTS levels drop abruptly to zero when smoking ends” (Klepeis, 533).

[Update, 20nov07: Orac at Respectful Insolence, has posted an interesting entry about a Dr. Siegel who tries to look at the exaggerations of the war on smoking and SHS]

Relative Risk (RR) of cancer from secondhand smoke approximate average = 1.3

(ie RR = risk of cancer for smokers/risk of cancer for non-smokers)
