Researchers have reported what they believe is the first documented death from a meat allergy that can be triggered by tick bites.  A 47-year-old New Jersey man died last year from alpha-gal syndrome, which in 2011 was first linked to bites from the Lone Star tick.  More than 100,000 people in the U.S. have become allergic to red meat since 2010 because of the syndrome, according to one estimate.

A peek inside some leading research labs shows how scientists-turned-detectives are painstakingly decoding what causes autoimmune diseases and how to stop the immune system from attacking you instead of protecting you.  Researchers use laser-powered machinery and brightly colored fluorescent dyes to tell rogue cells from normal ones.  Take Type 1 diabetes, caused when cells in the pancreas that produce insulin are gradually killed off by rogue T cells.
