94563 Discovery of a bottleneck relief in photosynthesis may have a major impact on food crops

Scientists have found how to relieve a bottleneck in the process by which plants transform sunlight into food, which may lead to an increase in crop production. They discovered that producing more of a protein that controls the rate in which electrons flow during photosynthesis, accelerates the whol... 2019-08-16 07:55:43 [anonymous]
94562 Could biological clocks in plants set the time for crop spraying?

Plants can tell the time, and this affects their responses to certain herbicides used in agriculture according to new research. The study found that plant circadian rhythms regulate the sensitivity of plants to a widely used herbicide according to the time of day. The findings could benefit agricult... 2019-08-16 07:55:40 [anonymous]
94561 New insight into bacterial infections found in the noses of healthy cattle

New research used the 'One Health' approach to study three bacterial species in the noses of young cattle and found the carriage of the bacteria was surprisingly different. The findings which combined ideas and methods from both animal and human health research could help prevent and control... 2019-08-16 07:55:38 [anonymous]
