Lake harvests are likely more fruitful than we knew

Harvests from freshwater fisheries such as the Great Lakes could total more than 12 million tons a year globally and contribute more to global food supplies and economies than previous estimates indicate, according to a study. …read more

Genetic engineering tool generates antioxidant-rich purple rice

Researchers in China have developed a genetic engineering approach capable of delivering many genes at once and used it to make rice endosperm — seed tissue that provides nutrients to the developing plant embryo — produce high levels of antioxidant-boosting pigments called anthocyanins. The resulting purple endosperm rice holds potential for decreasing the risk of certain cancers, cardiovascular disease, diabetes, and other chronic disorders. …read more

Slow motion makes soccer referees more likely to give a red card

Video assistant refereeing in soccer has to be used with caution. Researchers have shown that refs are more likely to give red when they see a foul committed in slow motion, even when a yellow card is more justifiable. This is because fouls viewed in slow motion appear to be more serious. …read more

Researchers discover novel colistin resistance gene mcr-3 in Escherichia coli 0

Researchers discover novel colistin resistance gene mcr-3 in Escherichia coli

A new mobile colistin resistance gene, mcr-3, has been discovered in E. coli of pig origin. The novel mcr-3 gene was discovered when a colistin-resistant Escherichia coli isolate tested negative for both mcr-1 and mcr-2. This novel mobile colistin resistance gene may already be widely disseminated. Screening for the mcr-3 gene should be urgently included in the surveillance of colistin-resistant Gram-negative pathogens from animals, humans, and the environment. …read more
