It’s hard for animals to find places that remain untouched by human beings. Berkeley wildlife ecologist Kaitlyn Gaynor and her colleagues noticed that the mammals they studied seemed to be more active at night than in the past. So they decided to investigate: Are animals all over the world “adjusting their daily activity patterns to avoid humans in time, given that it is becoming harder to avoid us in space”?
For parents, time often seems to fly by as the babies they could once hold in their hands all too quickly become toddlers, teens and adults. Keith Payne, a father as well as a professor of psychology and neuroscience, explains why we perceive time as whooshing by – and why, fortunately, it’s all in our heads.
For years, Mexico has helped stop undocumented migration into the U.S. by capturing and deporting Central Americans in transit. But the Trump administration’s immigration crackdown may be pushing America’s southern neighbor to change its strategy, writes Mexican human rights scholar Luís Gómez Romero. Far from demonizing Central Americans on the campaign trail, most Mexican presidential candidates now say Mexico should welcome refugees.

Trump's anti-immigrant policies are leading more Central Americans to stay put in Mexico. Mexico's presidential candidates have a lot to say about that, and none of it involves mass deportations.
