'Whiskey Webs' Could Be Used To Identify Counterfeit Spirits – 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.

Engineers test a powered 'ankle exoskeleton' to make running easier – 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...
