Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin? A new UCLA study pinpoints uniquely human patterns of gene activity in the brain that could shed light on how we evolved differently than our…
Despite government efforts to ban unapproved stem cell treatments, companies around China still offer them openly.
Climate change is set to reduce Latin America’s capacity to produce renewable energy, according to Roberto Schaeffer, a Brazilian energy planning expert.

The number isn’t quite a surprise, because it’s been rising at an accelerating…
What if it is too late to save the climate by cutting greenhouse gas emissions? What if the amount of carbon dioxide already added to the atmosphere by human activity is so great that it is going to produce big temperature changes no matter what, with big shifts in rainfall and in ocean chemistry? Options…
