Large Old Trees Grow Fastest, Storing More Carbon

THREE RIVERS, Calif, — Trees do not slow in their growth rate as they get older and larger — instead, their growth keeps accelerating, according to a study published in the journal Nature.

“This finding contradicts the usual assumption that tree growth eventually declines as trees get older and bigger,” says Nate Stephenson, the study’s lead author and a forest ecologist with the U.S. Geological Survey. “It also means that big, old trees are better at absorbing carbon from the atmosphere than has been commonly assumed.” (more…)

Trial to test using ultrasound to move kidney stones

Almost one in 10 people will someday experience a kidney stone, which creates what is described as the most intense pain imaginable. This increasingly common condition leads to hundreds of thousands of surgeries in the United States each year.

A new device developed at the University of Washington would let doctors use ultrasound to move kidney stones inside the body and help them pass by natural means. (more…)

Book explains astrobiology for a general audience

In the late 1990s, the University of Washington created what was arguably the world’s first graduate program in astrobiology, aimed at preparing scientists to hunt for life away from Earth. In 2001, David Catling became one of the first people brought to the UW specifically to teach astrobiology.

Catling, a UW professor of Earth and space sciences, is the author of Astrobiology: A Very Short Introduction, the 370^th offering in the Oxford University Press series of “very short introduction” books by experts in various fields. Catling was commissioned by editors to write the book, which was published in the United States on Jan. 1. Following are his answers to some questions about the book and astrobiology. (more…)

8 million lives saved since surgeon general’s tobacco warning 50 years ago

A Yale study estimates that 8 million lives have been saved in the United States as a result of anti-smoking measures that began 50 years ago this month with the groundbreaking report from the Surgeon General outlining the deadly consequences of tobacco use. The Yale School of Public Health-led analysis is published in the Journal of the American Medical Association.

The study used mathematical models to calculate the long-term effect of the seminal report, and subsequent anti-smoking measures, over the past half-century. These cumulative efforts have significantly reshaped public attitudes and behaviors concerning cigarettes and other forms of tobacco, note the researchers. (more…)

Updating Air Pollution Measurement Methods with UMass Amherst Air Quality, Health Effects Research

AMHERST, Mass. – Launching a natural research experiment in Kathmandu, Nepal, this month using advanced monitoring methods to assess health risk from air pollution, environmental health scientist Rick Peltier at the University of Massachusetts Amherst hopes to demonstrate for the first time in a real-world setting that air pollution can and should be regulated based on toxicology variables rather than simply on the volume of particles in the air.

Recent technological advances in air quality measurement methods now make it possible and practical to monitor air pollution in a much more sophisticated way than before, Peltier says. Researchers now use X-ray fluorescence spectrometry to measure air pollution metal content, ion chromatography to identify other chemicals and other tactics to assess organic and elemental carbon levels.

Record-Breaking Slide Would Bury Central Park 66 Feet Deep

Last year’s gigantic landslide at a Utah copper mine probably was the biggest nonvolcanic slide in North America’s modern history, and included two rock avalanches that happened 90 minutes apart and surprisingly triggered 16 small earthquakes, University of Utah scientists discovered.

The landslide – which moved at an average of almost 70 mph and reached estimated speeds of at least 100 mph – left a deposit so large it “would cover New York’s Central Park with about 20 meters (66 feet) of debris,” the researchers report in the January 2014 cover study in the Geological Society of America magazine GSA Today.

Saving the Great Plains water supply

Significant portions of the Ogallala Aquifer, one of the largest bodies of water in the United States, are at risk of drying up if it continues to be drained at its current rate.

In the current issue of Earth’s Future, a journal of the American Geophysical Union, Michigan State University scientists are proposing alternatives that will halt and hopefully reverse the unsustainable use of water drawdown in the aquifer. The body of water, also known as the High Plains Aquifer, spans from Texas to South Dakota and drives much of the region’s economy. (more…)
