5:00 PM | Get Over It: Men and Women Are from the Same Planet

Recent publication in PLoS ONE by psychologist Del Giudici and colleagues [i] has reignited the debate about just how “naturally” different men and women are. Del Giudici et al. state that their findings of a “pattern of global sex differences…may help elucidate the meaning and generality of the broad dimension of individual differences known as [...]

Video Tip of the Week: Canary Database for sentinels of human health

Recently we attended the Medical Library Association conference (#MLAnet13). Librarians are working so hard to wrangle information into usable forms, and to generate new connections among data types to reveal new information and leads for further studies. I ♥ librarians. In one of the sessions I attended on Medical Informatics, I heard several great talks. One [...]

Down in the underground, scuds lose eyes but keep genes

When animals live caves full time, their descendents often lose their eyes. It has happened over and over and over and over again, in all different kinds of animals. But how this happens is not obvious. Stephen Jay Gould wrote that some people would use cave fish as an argument that “Lamarck must have been on to something” with his idea that acquired characteristics can be inherited. Well, no, that’s not that case, but it is a good example of how tricky thinking about losses can be. The […]

The mystery of the missing experiments

Can experimental findings look too good to be true? Last week I wrote a blog post about some experiments showing a counterintuitive finding regarding how the need to urinate affects decision making. It’s since been brought to my attention that these experiments (along with dozens of others) have ...Read More

We Didn't Know This about Iron Before

It's amazing that we're still discovering things about our own planet at a time when we have the technology to explore planets other than our own. A study that was published in Nature Geoscience last week found that iron is weaker than previously thought. What's interesting about this is that we didn't know before this experiment how iron acted at high pressures, like those found in Earth's core.What we know about the composition of the center of the Earth is just made from inference. The […]
