12:25 PM | Dedifferentiation—Turning Back the Cellular Clock

“But a civilized man is better off than the savage in this respect. He can go up against gravitation in a balloon, and why should he not hope that ultimately he may be able to stop or accelerate his drift along the Time-Dimension, or even turn about and travel the other way?” in “The Time [...]

Exonerated but forever tarnished? On the lingering stigma toward the wrongfully convicted

Wrongful convictions are disturbingly common. It's estimated that over 1,050 people have suffered this fate in the USA alone. A new study, the first to systematically study stigma towards convicted innocents, finds that the old adage is true - mud sticks. Convictions may be overturned, but stigma persists. Kimberley Clow and Amy-May Leach surveyed 86 psychology students in Canada about either "people who have been wrongfully convicted of a crime"; "people who have been convicted of a crime […]

Wanna learn a second language? Ditch that familiar face.

Have you ever felt like you behave differently depending on your cultural surroundings? As an immigrant, I know I start mimicking others’ accents and body language once I’m out of my heritage culture. This type of environment-induced chameleon-like morphing is called – quite aptly – “frame switching” in psychology. Scientists don’t really know if it […]

LEGO Faces are Getting Angrier; So What?

Transport yourselves back to sprawling across the living room floor—colored blocks scattered like confetti about the carpet—building the highest towers and fattest spaceships (without directions, of course), all the while ignoring your parents' yelps as they step on a rogue piece. There's nothing quite like LEGO. And certainly there's nothing quite like those ubiquitious yellow, blocky LEGO faces. But a piece in The Daily Mail last week cites that "LEGO faces are getting angrier," and that […]

Thanks Dad!

Daddy's girl. Photo from freedigitalphotos.net.Let’s take a moment to appreciate just how special dads are. Across the animal kingdom, fathers caring for their young is the exception, not the rule. Paternal care is most often seen in species in which males can be pretty sure that they are indeed the father (for example, in species that fertilize eggs outside of the mothers’ bodies or in socially monogamous species). Mammals rarely act fatherly - Only 10% of mammalian species show […]
