There is something deeply repugnant about coming into contact with the clothing of someone we revile. It's as if a killer's evil might rub off on us.

Anatomically speaking, the clitoris has a checkered history. Even after some of the best known anatomists of the 16th century, among them Falloppia and De Graaf, apparently discovered the clitoris, more prominent ones, such as Vesalius and Galen denied its existence.

These are the best of times and the worst of times for the climate change cartoonist field. On the plus side, there is no problem coming up with new ideas. On the down side, there are new, horrifying climate findings being reported every day.

Cox and Graner conjectured that the whole cluster was becoming hexagonal to accommodate the hexagonal structure from the individual bubbles. I, on the other hand, conjectured that the whole cluster should become round to minimize the perimeter.

I realized that a universal moral imperative based on working to decrease suffering is something that I and, I think, many scientists could embrace, and upon which one might even become positively evangelical. More importantly, my student seemed to agree.

The petition to reform DSM 5 speaks with the powerful voice of more than 50 mental-health associations. It represents a significant percentage of the potential customers who eventually will have to decide whether or not DSM 5 is worth buying and using.

Global warming is an undisputed scientific fact now, and there is little doubt that this ominous trend is related to human activity, including the burning of fossil fuels. I completely accept the science of climate warming, yet I don't always do the right thing by my heirs. Why is that?

Cameron's achievements within exploration are a reminder that in an era of technological advancement there are still many new frontiers left to be explored.

The seemingly lifeless science of rocks and minerals is inextricably linked to biology. Life is among the most powerful agents of geological change. We cannot understand our planet's history without a keen sense of the coevolution of the geosphere and the biosphere.

A team of scientists from the Universities of Manchester and Sheffield has found that men don't need to live like monks if they want to become fathers. Rather than putting down the beer can, they should put down the too-tight tighty whities and opt for a pair of boxers instead.

The pattern of polarizing rhetoric and inability to compromise is sure to continue. However, both Democratic and Republican voters should insist their leaders act and agree to maintain funding for scientific research and development.

Because we have to rely so much on people around us to learn, it is important that we do a good job of figuring out who to trust to teach us well. This would seem to be a particular problem for children.

We have brought back James Dean to our current days' cool. I could breathe freely again. Cancel my tattoos' removal appointment. Light another smoke.

Maybe college students don't think about aging, but they think a lot about two things that will get them older faster.

From GZA and Neil deGrasse Tyson we learn that exposure to a multitude of positive experiences is the key to creating more options in the future for young people.

Carl Wieman, the Nobel-Prize-winning physicist who has been a key science official in the White House since 2010, has resigned from his government post for personal reasons. His departure provides an opportunity to reflect on his contributions in government as well as academia.

A major advance in our understanding of heredity and genetics is recognizing that organism characters are produced by networks and not by individual "gene products."
