Waterhemp has done it again. University of Illinois researchers just published an article in Pest Management Science confirming that waterhemp is the first weed to evolve resistance to HPPD-inhibiting herbicides. "A fifth example of resistance in one weed species is overwhelming evidence that resistance to virtually any herbicide used extensively on this species is possible," said Aaron Hager, U of I Extension weed specialist. Waterhemp is not a weed species that can be adequately managed...

Superbugs are not just a problem in hospitals but could be also coming from our animal farms. Research published in BioMed Central's open access journal BMC Microbiology indicates insects could be responsible for spreading antibiotic resistant bacteria from pigs to humans. Ludek Zurek and collaborators from Kansas and North Carolina State Universities isolated bacteria from farm pig feces and compared them to the bacteria present in the intestines of the house flies and German cockroaches...

In a little over seven hours, University of Illinois weed scientist Patrick Tranel got more genetic information about waterhemp than in two years time in a lab. The genetic information was obtained using pyrosequencing technology in the Keck Center at the U of I. The genetic sequence will allow scientists to study herbicide resistance in waterhemp.Ten years ago genomics was reserved for what Tranel refers to as "important species" such as humans, cows, fruit flies, and mice. "That's changed...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
