The Friday Five

Highlighting some of the coolest science news we’ve seen lately.

1. Birds of a feather really do flock together. A recent study finds that you and your friends have similar DNA.

2. Can science help us understand our political differences? Experiments in this new study show that conservatives respond significantly more rapidly to threatening stimuli.

3. You won’t believe the camouflage this gecko is capable of. The only thing better is its name:  the satanic leaf-tailed gecko.

4. Ivan Seah Yu Jun explains Alzheimer’s disease in under 5 minutes in this TED video.

5. So your friends scoff when you rather fist bump than handshake. Now science has justified your action. Fist bumps are the best way to greet someone without adopting their germs.
