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…)

Establishing World-Class Coral Reef Ecosystem Monitoring in Okinawa

Enduring two typhoons over a three-week period in August, Woods Hole Oceanographic Institution (WHOI) researchers, working in partnership with the Okinawa Institute of Science and Technology Graduate University (OIST), have successfully deployed an OceanCube Observatory System in waters off Motobu Peninsula, Japan — a biodiversity hotspot that is home to ecologically significant coral reefs. The observatory system enables real-time monitoring of temperature, salinity, and other chemical, biological and physical data critical to understanding the health of and changes in the coral reef ecosystem.

Okinawa is situated at the northernmost end of the border between the Pacific and the Indian Oceans. The coral reefs there support the highest diversity of endemic species, plants and animals in the world. These coral reefs are also economically valuable, generating as much as 3 trillion yen ($30 billion) globally, and 250 billion yen ($2.5 billion) in Japan. (more…)

Experts Team Up on Tsunami Resilience in California

While scientists can’t predict when a great earthquake producing a pan-Pacific tsunami will occur, thanks to new tools being developed by federal and state officials, scientists can now offer more accurate insight into the likely impacts when tsunamis occur. This knowledge can lead officials and the public to reduce the risk of the future tsunamis that will impact California.

What are the potential economic impacts? Which marinas could be destroyed? Who needs to be prepared for evacuations? A newly published report looks at these factors and more. (more…)

The New Face of Mining: Women Carving Out a Place in Surging Industry

The UA department of mining and geological engineering, one of only 14 U.S. schools offering mining engineering degrees and only a handful with its own student mine, is dedicated to helping fill the industry pipeline, and that includes ensuring female engineers continue to gain ground in a surging industry.

They roam the remotest corners of the world, scale the highest mountains and descend deep into the Earth.

They go places few women have ever gone. They are not afraid of getting dirty, or of much else for that matter, certainly not adversity or a good challenge. And they know, better than most, how and when to take a joke. (more…)

How Silver Turns People Blue

Ingesting silver — in antimicrobial health tonics or for extensive medical treatments involving silver — can cause argyria, condition in which the skin turns grayish-blue. Brown researchers have discovered how that happens. The process is similar to developing black-and-white photographs, and it’s not just the silver.

PROVIDENCE, R.I. [Brown University] — Researchers from Brown University have shown for the first time how ingesting too much silver can cause argyria, a rare condition in which patients’ skin turns a striking shade of grayish blue.

“It’s the first conceptual model giving the whole picture of how one develops this condition,” said Robert Hurt, professor of engineering at Brown and part of the research team. “What’s interesting here is that the particles someone ingests aren’t the particles that ultimately cause the disorder.” (more…)

Wind Power’s Potential

UD-Stanford team calculates maximum global energy potential from wind

Wind turbines could power half the world’s future energy demands with minimal environmental impact, according to new research published by University of Delaware and Stanford University scientists in the Proceedings of the National Academy of Sciences.

The researchers arrived at the determination by calculating the maximum theoretical potential of wind power worldwide, taking into account the effects that numerous wind turbines would have on surface temperatures, water vapor, atmospheric circulations and other climatic considerations.

“Wind power is very safe from the climate point of view,” said Cristina Archer, associate professor of geography and physical ocean science and engineering at UD. (more…)

Employees at ‘Green’ Companies are Significantly more Productive, Study Finds

Bucking the idea that environmentalism hurts economic performance, a new UCLA-led study has found that companies that voluntarily adopt international “green” practices and standards have employees who are 16 percent more productive than the average.

Professor Magali Delmas, an environmental economist at UCLA’s Institute of the Environment and Sustainability and the UCLA Anderson School of Management, and Sanja Pekovic from France’s University Paris–Dauphine are the first to study how a firm’s environmental commitment affects its productivity.

Their findings are published online Sept. 10 in the Journal of Organizational Behavior. (more…)

Despite Efforts for Change, Bangladeshi Women Prefer to Use Pollution-Causing Cookstoves

Women in rural Bangladesh prefer inexpensive, traditional stoves for cooking over modern ones — despite significant health risks, according to a Yale study in the Proceedings of the National Academy of Sciences.

A large majority of respondents (94%) believed that indoor smoke from the traditional stoves is harmful. Still, Bangladeshi women opted for traditional cookstove technology so they could afford basic needs.

“Non-traditional cookstoves might be more successful if they were designed with features valued more highly by users, such as reducing operating costs even if they might not reduce environmental impact,” said Mushfiq Mobarak, a co-author and associate professor of economics at the Yale School of Management.
