Organic milk has more beneficial fats than conventional milk, at least in the United Kingdom, says a new study. Whether these differences are nutritionally significant is less clear. Surveys of U.S. milk have yielded different results, though they also show differences between organic and conventional milk.

With climate change predicted to alter precipitation and raise temperatures in North American grain-growing regions by 3 to 4 degrees Celsius (about 5 to 7 degrees Fahrenheit) by the end of the century, crops in the future will face dramatically different growing conditions than they do today. But a new study shows that over the…

Planting more reflective versions of crops could cool regional temperatures in summertime, reducing the impact of increasing global temperatures in these areas, according to ongoing research. Increasing the reflectivity of crop plants by 20 percent could decrease temperatures in a given area by about one degree Celsius (1.8 degrees Fahrenheit), said Joy Singarayer of the…
