Me and my microbes In the past decade or so, the microbiota, the community of microbes that makes its home in the guts of humans and other animals, has become quite a popular research topic. Quite rightly so, since our little guests seem to affect aspects of our lives that we wouldn’t necessarily consider to […]... Read more »

A new study using aerial imagery across the state of California has found that converting land to grow almonds between 2007 and 2014 has led to a 27% annual increase in irrigation demands—despite the state's historic drought. The expansion of almonds has also consumed 16,000 acres of wetlands and will likely put additional pressure on already stressed honeybee populations.

According to new research, widespread adoption of genetically modified crops has decreased the use of insecticides, but increased the use of weed-killing herbicides as weeds become more resistant. This is the largest study of genetically modified crops and pesticide use to date. The team of economists studied annual data from more than 5,000 soybean and 5,000 maize farmers in the U.S. from 1998 to 2011, far exceeding previous studies that have been limited to one or two years of data.

Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.

With nearly sixty percent of American adults now taking prescription medications--from antidepressants to cholesterol treatments--there is growing concern about how many drugs are flowing through wastewater treatment facilities and into rivers and lakes. Research confirms that pharmaceutical pollution can cause damage to fish and other ecological problems--and may pose risks to human health too.

The bacteria in and on our bodies have been shown to be vital for human health, influencing nutrition, obesity and protection from diseases. But science has only recently delved into the importance of the microbiome of plants. Since plants can't move, they are especially reliant on partnerships with microbes to help them get nutrients.
