Our dogs understand us better than they’ve been given credit for — and scientists say they have the brain wave evidence to prove it. By placing electrodes on the heads of 18 pet dogs, researchers found striking evidence that the animals did not merely recognize the patterns of sound that…

To help California fight climate change, air quality regulators would like to see 20% of the state’s farmland go organic by 2045. That means converting about 65,000 acres of conventional fields to organic practices every year. But depending on how that transition happens, the change could lead to an overall…
