science20.com – We know the left and right side of our brain are specialized for cognitive abilities like language (left hemisphere) and the right hand. That functional lateralization is reflected by morphological asymmetry too. The left and right hemispheres differ subtly in brain anatomy, distribution of nerve cells, connectivity and even neurochemistry.

science20.com – When a drop of liquid evaporates, solids are left behind in a pattern that depends on what the liquid is, what solids are in it and the environmental conditions. You may have seen a 'coffee ring' when overflow deposits solids along the edge of the puddle as it evaporates. The same things happen with other beverages.

engadget.com – Ankle exoskeletons could help you run longer and faster and even serve as a new mode of transportation, according to a team of Stanford University engineers. The engineers tested a motorized exoskeleton rig that attaches around the ankle and foot and found that it made running 15 percent easier. They explained that when the exoskeleton's motor is switched on, it reduces the energy cost of running and allows the user to run longer than they're usually capable of. The device can also boost a...
