Fruit fly protein found to aid healing in mamals

Biologists at the University of California, San Diego have determined that a protein essential for the normal embryonic development of fruit flies is also used by mammals to assist in the timely healing of cuts and lacerations. Their discovery, detailed in the June 3 issue of the journal Developmental Cell, provides new insight for scientists into the molecular mechanisms responsible for wound healing in humans and may one day lead to the design of new drugs for individuals whose healing is compromised.

Family lives with 2,000-plus brown recluse spiders without bites

Have you had a skin wound lately and did a physician tell you a brown recluse spider was the culprit? A California study, focusing on 2,055 brown recluse spiders in a Kansas home, notes that many skin lesions are misdiagnosed by doctors as “brown recluse spider bites.” The study finds that even where brown recluses can be very common, bites from these spiders are uncommon. Moreover, the study finds that in non-endemic areas, there aren’t enough brown recluses to account for skin conditions diagnosed as “brown recluse bites.”
