Training Brains:  Sheena Josselyn’s lab at SickKids specifically erased a fear memory in mice by selectively ablating CREB neurons using an inducible diptheria toxin.  Let me break this down, because it’s so unbelievably cool: 

  • they trained mice to be afraid of a sound,
  • then they destroyed some specific cells in the brains of the mice,
  • then the mice forgot that they were afraid of the sound.

The mice were subsequently able to learn new things, like how to find cheese in a maze, and were even able to learn to be afraid of the same sound again.  Between this and the mind-reading experiment in the UK this week, it’s enough to give you a serious bout of insomnia … which often lasts over a year, according to researchers at Laval.

Gout Rout: Dr. Hyon Choi and colleagues at the University of British Columbia reported in Monday’s issue of the Archives of Internal Medicine, that Vitamin C appeared to lower the levels of uric acid in the blood, and that men who take in more vitamin C appear to be less likely to develop gout, a painful type of arthritis.

Beef Relief: Researchers using Bioniche’s E. coli O157 vaccine, Econiche™, published a study in Foodborne Pathogens and Disease showing that vaccinated cattle were 92% less likely to be colonized with E. coli O157:H7 than non-vaccinated cattle (odds ratio (OR)=0.07, p=0.0008). This is the second published study demonstrating more than 90% effectiveness of the Bioniche vaccine against colonization.
