As part of NPR's coverage of this year's presidential election, All Things Considered asked three science reporters to weigh in on the race. The result is a three-part series on the science of leadership. In Part 1, Alix Spiegel looked at the personalities of American presidents.
Voters could learn some things about choosing a leader from a fish. Or a chimp. Or an elephant.

Consider: two scientists are asked whether there's any doubt that humans are responsible for climate change. The first says, "It's a fact humans are causing climate change – there's no room for doubt." The second replies, "The evidence for anthropogenic climate change is overwhelming, but in science there's always room for doubt."
The first scientist is probably a more effective spokesperson for the scientific consensus. But the second scientist is providing a more accurate representation of how science works.

I grew up in Greenwich Village, not that far from the campus of New York University. Back in the 1970s campus demonstrations were pretty common, but I remember one in particular. I was walking by myself toward Washington Square Park and I came upon what was a small but very energetic and frightening protest. I think what made the encounter scary for me was that the students were objecting to the presence on campus of a "Nazi," who, apparently, was coming to give a lecture. Or maybe what I found disturbing was that I found it hard to believe the protesters.
If you're reading this blog, you're probably into food. Perhaps you're even one of those people whose world revolves around your Viking stove and who believes that cooking defines us as civilized creatures.
Well, on the latter part, you'd be right. At least according to some neuroscientists from Brazil.
Scientists around the world were stunned yesterday when a judge in Italy found six Italian earthquake experts and a government official guilty of manslaughter. The judge found that the men downplayed the risk of a major earthquake in the city of L'Aquila. A 6.3 magnitude quake struck in early April 2009 and killed more than 300 people. Shortly before that earthquake struck, the scientists had held a meeting in L'Aquila to examine a recent spate of tremors, a so-called swarm of seismic activity.
These are baby bats — embryos actually. They remind me of those See No Evil, Say No Evil, Hear No Evil monkey pictures I saw growing up, but these little guys are much, much cuter. And, of course, being bats, the hearing thing doesn't apply. Bats don't hear with our kind of ears, so of course, there's no covering-ears-up picture. That wouldn't make bat sense.
Add all of us up, all 7 billion human beings on earth, and clumped together we weigh roughly 750 billion pounds. That, says Harvard biologist E.O. Wilson, is more than 100 times the biomass of any large animal that's ever walked the Earth. And we're still multiplying. Most demographers say we will hit 9 billion before we peak, and what happens then?
