...while these hormones have been successfully manipulated in lab mice to prompt weight gain or loss, the same has not been true in humans. Experiments in which obese human patients were injected with leptin have failed, because the metabolic pathways that control hunger and fullness in people are far more complex than they are in mice. Knocking out one of, say, 50 such pathways through drug treatment just means the other 49 will eventually pick up the slack, says Dr. George Fielding, a bariatric surgeon at the NYU Program for Surgical Weight Loss...
...then something else happened - us. The Science researchers found that during the 20th century, as human beings began pouring greenhouse gases into the atmosphere, the Arctic stopped cooling and started warming. Even though the Arctic is still gradually getting less sunlight, it's still getting hotter - summer temperatures in the Arctic are 1.4 degrees C higher than they would have been if the cooling had continued unabated, according to the study. The most recent decade recorded - from 1999 to 2008 - was the warmest of the past 2,000 years. The recent warming trend has been so strong that researchers...

...placed too much faith in client-states to keep the peace. Exhibit A: Ramzan Kadyrov. Kadyrov was hailed as a success by Putin, who has painted himself as a strongman who brought peace and prosperity to Russia. But Kadyrov is a thug whose militia are guilty of every human-rights abuse imaginable; when the Russians ended their 10-year counterterrorism operations in the region earlier this year, violence surged...
