Three Ways to Improve Your Indoor Air Quality Naturally

While outdoor pollution always seems to be on the forefront of all of our minds, many people don’t stop to consider the quality of the air indoors and inside their own home. It is a little known fact that indoor air quality can be up to five times worse than outdoor air quality. Additionally, the EPA has ranked indoor air pollution as one of the top five environmental concerns that we face on a daily basis and that up to 50% of illnesses are caused or made worse by inadequate indoor air quality. When you stop to think about these statistics, it is concerning that we spend most of our time in our homes being exposed to these pollutants. This article will discuss some simple ways to improve your indoor air quality in your home naturally so that you and your family can remain safe and healthy.

Too Hot to Exercise? New Research Links Obesity to Temperature and Humidity

AUSTIN, Texas — If you live in the South and have trouble exercising during the muggy summer months, you’re not alone. New research by researchers at The University of Texas at Austin has found that adults are less physically active — and more obese — in counties where summers are hot, especially if they are also humid or rainy.

The new study, which appears in the American Journal of Public Health, also found that adults are less active and more obese in counties where winters are especially cold, cloudy and dark. (more…)

Geothermal Energy Keeps Turkeys Comfortable and Saves Farmers’ Money; Prototype Designed by MU Engineer

COLUMBIA, Mo. — While Americans prepare to cook millions of turkeys for Thanksgiving, a geothermal energy system developed by a University of Missouri engineer will be keeping live turkeys toasty during the chilly autumn weather. In a prototype facility, designed by a University of Missouri engineer, environmentally and economically friendly geothermal energy is keeping turkeys comfortable during both cold and hot weather. The system is designed to reduce utility costs while improving the air quality for the birds.

“This is our first prototype of a geothermal system in a commercial livestock operation,” said Yun-Sheng Xu, associate research professor in civil and environmental engineering. “Our first set of performance data suggests that farmers could cut their heating costs in half at current propane prices. Currently, two units are installed at the test farm. Other farmers could begin installing units on their turkey farms as soon as next year, for use by next winter.” (more…)

Researchers Devise More Accurate Method for Predicting Hurricane Activity

Researchers from North Carolina State University have developed a new method for forecasting seasonal hurricane activity that is 15 percent more accurate than previous techniques.

“This approach should give policymakers more reliable information than current state-of-the-art methods,” says Dr. Nagiza Samatova, an associate professor of computer science at NC State and co-author of a paper describing the work. “This will hopefully give them more confidence in planning for the hurricane season.” (more…)

Researchers Develop New, Less Expensive Nanolithography Technique

Researchers from North Carolina State University have developed a new nanolithography technique that is less expensive than other approaches and can be used to create technologies with biomedical applications.

“Among other things, this type of lithography can be used to manufacture chips for use in biological sensors that can identify target molecules, such as proteins or genetic material associated with specific medical conditions,” says Dr. Albena Ivanisevic, co-author of a paper describing the research. Ivanisevic is an associate professor of materials science and engineering at NC State and associate professor of the joint biomedical engineering program at NC State and the University of North Carolina at Chapel Hill. Nanolithography is a way of printing patterns at the nanoscale. (more…)

Got Milk? Climate Change Means Stressed Cows in Southern U.S. May Have Less

“Cows are happy in parts of Northern California and not in Florida” is a good way to sum up the findings of new research from the University of Washington, said Yoram Bauman, best known as the “stand-up economist.”

Bauman and colleagues found that the decline in milk production due to climate change will vary across the U.S., since there are significant differences in humidity and how much the temperature swings between night and day across the country. For instance, the humidity and hot nights make the Southeast the most unfriendly place in the country for dairy cows.

Their study combined high-resolution climate data and county-level dairy industry data with a method for figuring out how weather affects milk production. The result is a more detailed report than previous studies and includes a county-by-county assessment — that will be available to farmers — of the impact climate change will have on Holstein milk production in the U.S. through 2080.

The Depths of Winter: How Much Snow Is In Fact On the Ground?

*Will lasers and GPS technology finally enable accurate measurement of snowfall?*

Equipped with specialized lasers and GPS technology, scientists are working to address a critical wintertime weather challenge: how to accurately measure the amount of snow on the ground.

Transportation crews, water managers and others who make vital safety decisions need precise measurements of how snow depth varies across wide areas. (more…)
