Plastic processors and machinery suppliers collaborate as productivity gains score over price
Although price is a significant purchase factor, plastic processors are forging partnerships with their machinery suppliers based on quality of products and service. These partnerships, especially among multinational corporations, have to be flexible no matter which sector (primary, auxiliary, software, or services) the processing equipment is meant for.

Threatened juvenile salmon get scientific assistance
Research has found that thousands of miles of essential juvenile salmon habitat are blocked by tens of thousands of culverts that lay beneath Pacific Northwest roadways. Many of these culverts - that for years have successfully channeled water under roadbeds - are acting as barriers to young salmon preventing them the upstream passage required for growth and development.

Hydrothermal vent systems could have persisted for millions of years, incubated early life
The staying power of sea-floor hydrothermal vent systems like the bizarre Lost City vent field is one reason they also may have been incubators of Earth's earliest life, scientists report in a paper published in the July 25 issue of Science. (2003-07-24)

Hydrothermal vent systems could have persisted millions of years, incubated life
The staying power of seafloor hydrothermal vent systems like the bizarre Lost City vent field, discovered just 2 ½ years ago, is one reason they also may have been incubators of Earth's earliest life. If hydrothermal venting can occur without volcanism, it also means explorers may have more places than previously thought to look for microbial life in the universe. (2003-07-24)

Navy's new 'gunk-o-lyzer'?
Ten years ago, John Reintjes watched as Navy ships took regular oil samples from their lubricating systems and sent them ashore to be analyzed. Fine debris and particulate matter suspended in a ship's oil reservoirs points to trouble. Up to three months might pass before analysts' results were returned to the ship. This could be well after an engine or mechanical system breakdown or catastrophic failure might have already occurred. (2002-04-24)

Antarctic ice shelf collapses in largest event of last 30 years
Recent satellite imagery analyzed at the National Snow and Ice Data Center at the University of Colorado at Boulder has revealed that the northern section of the Larsen B ice shelf, a large floating ice mass on the eastern side of the Antarctic Peninsula, has shattered and separated from the continent in the largest single event in a 30-year series of ice shelf retreats in the peninsula.

Men with higher levels of PCBs more likely to father boys
A Michigan State University study indicating that men with higher levels of PCBs in their bodies are more likely to father boys than girls is more evidence of the effects environmental contaminants can have on the human body. The study, using data from three separate studies in which PCB levels were measured in the bodies of men who ate Lake Michigan fish, found that of the 208 children born to those men, more than 57 percent were boys. (2002-01-28)

Measurements of an exposed earthquake fault helps scientists understand subsurface faults' behavior, improve hazard forecasts
Geological scientists know something of the causes of earthquakes, and they know where many faults are located. However, they know much less about the rocks within the fault zone that control earthquake properties. But seismic studies of an exposed fault are now providing new information - and at least one mystery. (2001-04-04)

Guidelines developed for hydraulic design of safer canoe chutes
With the advent of warmer weather, many outdoor enthusiasts are taking to the water in canoes and kayaks. Some boaters, blocked in their travels by one of the myriad dams that dot the nation's waterways, may attempt to navigate the spillway - a dangerous practice that could result in death by drowning in the strong undertow that forms at the base of a dam. University of Illinois scientists have a safer alternative: properly designed passageways called canoe chutes. (2001-04-01)

Ancient quakes leave mark from Kentucky to New York

Midwest geologists propose new view of ancient continental collisions
A team of Midwest geologists will present evidence at the Geological Society of America annual meeting supporting a new world view from the Ordovician Period. Unlike a previous model which showed the future North and South American land masses colliding near the equator, the new model is consistent with evidence that an Ice Age affected South America late in the Ordovician.
