While you indulge in some Easter Peeps and chocolates this weekend, you might want to think about all that sugar. No, this isn't a calorie warning. In the U.S., raw sugar can cost twice the world average.
Critics say U.S. sugar policy artificially inflates sugar prices to benefit an exclusive group of processors — even though it leads to higher food prices. But this year, prices fell anyway. Now, the government could be poised to use taxpayer dollars to buy up the excess sugar.
There's a mystery in West Africa that's puzzled scientists for years. Strange circles of bare soil appear in grassland; they're commonly called "fairy circles." These naturally occurring shapes last for decades, until the grass eventually takes over and the circles fade.
Now German scientists think they have an explanation — a horde of insects seems to be bioengineering thousands of miles of desert.
When workplace safety expert Eric Esswein got a chance to see fracking in action not too long ago, what he noticed was all the dust.
It was coming off big machines used to haul around huge loads of sand. The sand is a critical part of the hydraulic fracturing method of oil and gas extraction. After workers drill down into rock, they create fractures in that rock by pumping in a mixture of water, chemicals and sand. The sand keeps the cracks propped open so that oil and gas are released.
