A group of researchers are contending obese kids may not be the result of lax parenting or a junk-food culture; obesity may have an infectious origin, according to a cross-sectional study by University of California, San Diego School of Medicine researchers who correlate children exposed to a particular strain of adenovirus, human adenovirus 36 (HAdV-36 or AD-36), being significantly more likely to be obese with some causation. 
It's been hard for archaeologists to pin down the extent of idle wealth in ancient people, but it is generally believed only those in the richest locations, like capital cities, had it.   

A recent discovery, in an urban context and at an orderly archaeological dig, may be of great significance in learning about ancient people outside large cities.  Most small pieces of art originating in the Near East are of unknown origin, having been displaced through illegal antique trade, or purchased by museums and collectors before scientific archaeological research began, but an ornately designed signet ring of Apollo may lend some insight into the economic state of ancient Phoenicians.
