The Neurological Complications Of Lyme Disease

Lyme disease is caused by a bacterial organism that is transmitted to humans via the bite of an infected tick. Most people bitten by an infected tick develop a characteristic skin rash around the area of the bite. The rash may feel hot to the touch, and vary in size, shape, and color, but it will often have a “bull’s eye” appearance (a red ring ...

A Shear Mystery

ShearMysteryEveryone has had problems with a ketchup bottle at one time or another. After struggling and only getting a few drops, a flood suddenly gushes out and buries your food. With perfect timing, the ketchup changes from a thick paste to a runny liquid. If you find yourself wondering 'why?' you're in good company. Physicists are puzzled, too.

Ketchup is one of many complex fluids - including whipped cream, blood, film emulsions, nail polish and some plastics - that share a property called 'shear thinning.' Normally thick like honey, they can become thin and flow like water when stirred or shaken. The phenomenon is common enough, yet scientists aren't sure why it happens.

The ketchup-like behavior of pure fluids at their critical point is still only theoretical. Even simulations using supercomputers can't prove the theory. Think of that the next time you whack the bottom of a ketchup bottle. Even supercomputers can't predict the outcome!
