Inches of rain to bring pests

JANESVILLE, Wis. (AP) — The eight inches of rain that fell in some parts of central Wisconsin over the last three days will bring back an unwanted pest – mosquitoes.

So says University of Wisconsin Extension entomologist Phil Pellitteri.

Pellitteri says people will notice an increase in the biting insects.

From eggs to landfills: live chickens at the dump?

Capital Times

Liz and Garrett Perry were dropping off scrap lumber and old shingles from a garage roofing project at the Deer Track Park landfill when they saw what appeared to be a bloody chicken darting between the big trash bearing rigs roaring through the massive dump just off Interstate 94 near Johnson Creek.

Throwing cold water on hot-weather myths

Wisconsin State Journal

Like ghost stories around the campfire, hot weather myths are part of summer.

There are the endearing, the enduring and the just plain ridiculous — dogs with sweaty paws, potato salad’s bacteria bonanza, air-conditioning-induced colds.

So what about these almost believable, almost dismissable summer legends?

Bridge terms may face change (Appleton Post-Crescent)

Appleton Post-Crescent

The collapse of Minnesotaâ??s busiest bridge will lead to revisions in the terminology inspectors use to label conditions of the structures, predicts an expert in bridge ratings.

The term â??structurally deficientâ? â?? used to describe the Interstate 35W bridge in Minneapolis and more than 2,000 bridges in Wisconsin â?? can be misleading, said Lawrence Bank, a civil and environmental engineering professor at the University of Wisconsin-Madison.

Hearing that twenty-one hundred bridges in Wisconsin are deficient doesn’t mean they’re ready to collapse.

There are degrees of deficiency according to UW-Madison Civil Engineering professor Mike Oliva. And, he says, that doesn’t mean a bridge declared deficient is necessarily ready to collapse. It could mean inspectors need to take a closer look to see what’s going on and keep close track of it.

Wisconsin Bridge Safety

Wisconsin officials have dealt with bridge section failures in the past. They will be watching Minnesota’s bridge collapse investigation closely, and preparing to make safety changes here, if problems are discovered which apply to Wisconsin’s bridge structures.

UW-Madison bridge engineering professor Mike Oliva said the design of Minneapolis’ 35-W bridge reflects an older design without newer safety features. “The industry is definitely moving away from bridges where there are critical members that cause a collapse.”

“Structurally deficient” does not necessarily imply a bridge is dangerous, said Lawrence Bank, a professor in the Department of Civil and Environmental Engineering at the University of Wisconsin at Madison. It means the bridge has undergone wear and tear.

“Structurally deficient means that some or all of the components of the bridge might not meet their original design capacities. They may have degraded in some way,” Bank said. “Not everything is expected to remain in a new and pristine state.”

Bridge repairs could cost state over $2 billion

Michael Oliva, a structural engineer at UW-Madison, agreed the state’s bridges are in better shape than the national average. But the Minnesota collapse was sobering, he said, because large portions of the bridge failed.

“Even for an engineer like myself, this is scary because we never expect this to happen in design,” Oliva said, noting that most bridges are engineered so that at most only a limited section of the bridge can fail.

Curiosities: No proof that lasers help people stop smoking

Wisconsin State Journal

Q. There’s a new stop-smoking treatment being advertised on TV somehow using lasers. What is this and how does it work?
A. The method uses low-power lasers to stimulate parts of the body much like acupuncture. The catch, according to Michael Fiore of the UW-Madison Center for Tobacco Research and Intervention, is that acupuncture as a means to quit puffing has not been determined by the U.S. Public Health Service to be effective and is not supported by science.

Study warns of emission of fine particles

Your office laser printer may be hazardous to your health.

That’s because some printers emit large quantities of very fine particles that can be breathed into the lungs, according to a study by Australian researchers at the International Laboratory for Air Quality and Health at the Queensland University of Technology.

A ‘China opening’ to Iran?

Historian Jeremi Suri writes:

President Bush confronts a civil war in Iraq with no end in sight, American standing abroad has plummeted and domestic opposition to present policies is growing. America’s long time adversary, Iran, similarly contends with a clash of generations and worldviews at home, as well as a cast of external challengers, including the International Atomic Energy Agency and the UN Security Council.

Leaders in Washington and Tehran need one another. The White House should pursue a “China opening” with Iran.
