Matt Cordes, a UA associate professor in the department of chemistry and biochemistry, led the team that discovered that the venom of some spiders in the genus Loxosceles causes a different reaction in the body than previously thought. Arachnologist Greta Binford, an associate professor of biology at Lewis and Clark College in Portland, Ore. who completed her PhD and postdoctoral studies at the UA, searches the world for spiders and milks their venom to study its chemical compounds. It usually depends on the spider which bit you, but lets say it's not a spider which could be venomous, even if it were to stay in your body, it'd be harmless. Many bites attributed to spiders turn out to have been inflicted by other bugs. Biological poisons (toxins) are generally degraded in the body in short order, so it’s not possible for them to “resurface” at a later time. The research team includes Cordes; Vahe Bandarian, an associate professor also in the UA's department of chemistry and biochemistry; and Greta Binford, an associate professor of biology at Lewis and Clark College in Portland, Ore. who, completed her doctorate and a postdoc at the UA. This type of venom “can also attack the body’s supply of ATP, a nucleotide which is critical in energy transfer between cells” (wisegeek). "We found something more interesting.".
