It's counterintuitive but psychologists say we tend to remember unattractive faces more likely than attractive ones - attractive faces leave much less distinctive impressions on our memory unless they have particularly remarkable features.

Population health has a lot of different factors - and infant mortality is one of them but it doesn't tell the entire story. Some in America laud Cuban health care, for example, but Cuba just had a cholera epidemic, something that doesn't happen in the United States.

And Cubans abort babies if there are signs of trouble, as do many industrialized nations, while America does not. Trying to save more babies is one reason why America ranks 27th among industrialized nations in infant mortality, and if you are in the business of criticizing American health care, you can stop thinking critically right there. 

Estimates say there are over 3,000,000 registered freelancers worldwide, competing for everything from computer programming and web design to finance and engineering.

How can you make yourself more attractive to potential employers?  

Does home field advantage matter? In baseball outfielders, the tricks and corners of a new baseball park might be meaningful but that effect should diminish over time. The Seattle Seahawks have a famously loud stadium and the team calls the audience "the twelfth man" but they didn't need it to rout the Denver Broncos in the Super Bowl.

There are no athletes in the Olympics who are from Sochi, yet psychologists believe that Russian athletes will have a psychological edge, even though Russia covers 6,600,000 million square miles, because they have a home field advantage.

While there is a glut of PhDs in academia, to an extent where some post-doc jobs don't even pay anything, the President's Council of Advisors on Science and Technology said in 2012 that America will need an additional 1,000,000 science, technology, engineering and mathematics (STEM) graduates in the United States over the next decade to meet corporate economic needs. In a speech last week he ridiculed art history majors. He loves scientists and wants more of them.

Organic farms support more biodiversity, supporting 34% more plant, insect and animal species than conventional farms, according to a new paper. For pollinators such as bees, the number of different species was 50% higher on organic farms, although the authors stress that the study only looked at 'species richness'.
