Running from math

By Ashley Yeager

. . . 158 . . . 159 . . . 160.

In the first minute of my morning run, my feet strike the ground 160 times, 80 times each foot.

Yes, I count. But not for the whole run. I cheat and do the math.

It's pretty astounding to calculate that in a short, 30-minute jog through Duke Forest, each foot hits the dirt 2,400 times.

Heliconius erato butterflies

Flying high on stolen wings

Guest post by Viviane Callier, Duke biology

The wing color patterns on some butterfly species have evolved to copy wings on other butterfly species. In Heliconius butterflies, which are toxic to birds, the convergence of several species on the same wing color pattern gives them all mutual benefit – birds recognize one pattern saying “I’m poisonous; don’t eat me!"

Seeing the quarks in particle collisions

By Ashley Yeager

Quarks are prisoners to their nuclear family. The sub-atomic particles are rooted so deep within their protons and neutrons that it takes an extreme amount of energy for them to escape.

Though extreme, that energy barrier hasn’t deterred scientists from trying to set the quarks free.

Math department ranks 10th in world

By Ashley Yeager

Bet you've never seen a molecule dance. You'd probably never think that a molecule's jitterbug would make Duke the tenth best school in the world for studying math, either.

But, this dance, called Brownian motion, is among the subjects Duke mathematicians have tackled in their research.

ring-tails

Sir Richard's Possible Folly

Moving animals, like the ring-tailed lemur, from one continent to another to save the species hasn't been done often and typically isn’t successful.

But that hasn't deterred businessman and adventure tycoon Sir Richard Branson from announcing plans to import 30 ring-tailed lemurs from global zoos to his private island of Moskito, located in the Caribbean.
