Royal Victim: 5 Most Incredible Discoveries of the Week

A surprise find about certain migraines and an explanation for blah-tasting tomatoes were among the interesting discoveries of the week:

• Skeleton Found in Castle May Be That of Doomed Lover: Construction workers fixing up a German castle may have stumbled across the remains of a Swedish count murdered more than 322 years ago in a tangled love story gone wrong. The body is believed to be that of a man who had the misfortune of falling for the wife of the future King George I of Britain. People figured he'd been murdered over the affair, but his body had never been found.
• Scientists May Have Discovered Migraine Trigger: Certain foods like chocolate, wine, and processed meats have long been linked to migraines, and while nitrates in those foods are often seen as the culprit, it's not entirely clear why some people are more susceptible. Now scientists think they know: It's all about bacteria in their mouths. Might a migraine mouthwash be near?
• Why Tomatoes Lose Their Flavor in the Fridge: Salad lovers might already know that storing tomatoes in the fridge robs them of flavor, and now scientists think they've figured out why. When chilled tomatoes are brought back to room temperature, telltale genes that affect taste are turned off—permanently. This does not bode well for those who get their tomatoes from supermarkets.

• Ancient Bison Mystery Solved: Scientists were never sure how the modern European bison appeared seemingly out of nowhere about 11,000 years ago. New research provides an answer: It seems the now-extinct steppe bison mated with the aurochs, the ancestor of cows, and created a rare hybrid mammal. The discovery answers an ancient question about cave drawings, too.
• Commuter Study Reveals an Advantage of the Rich: Chalk up one more health advantage for the rich over the poor: more sleep. Researchers in Colombia crunched data about the movement of residents in two big cities and found that rich and poor people traveled longer distances to get to work than the middle class—but their journeys were very different. Poorer residents left their homes at 5 or 6am, at least an hour earlier than their wealthier counterparts. That seemingly minor difference speaks volumes about the income divide.
