Cuddling cows
OPINION: Years of floods and low food prices have driven a dairy farm in England's northeast to stop milking its cows and instead charge visitors to cuddle them.
University of Auckland affiliated researchers Lindsay Matthews and Douglas Elliffe believe their research with German colleagues could help reduce water contamination and greenhouse gas emissions.
If cows could be trained to urinate in a 'toilet', at least some of the time, nitrogen could be captured and dealt with before it reaches waterways or turns into nitrous oxide gas. Matthews and Elliffe's research has been published in the prestigious journal Current Biology and is profiled in Science.
