New approach makes AI adaptable for computer vision in crop breeding

Scientists developed a machine-learning tool that can teach itself, with minimal external guidance, to differentiate between aerial images of flowering and nonflowering grasses — an advance that will greatly increase the pace of agricultural field research, they say. The work was conducted using images of thousands of varieties of Miscanthus grasses, each of which has its own flowering traits and timing.

Illinois leads most rigorous agricultural greenhouse gas emissions study to date

Farmers apply nitrogen fertilizers to crops to boost yields, feeding more people and livestock. But when there’s more fertilizer than the crop can take up, some of the excess can be converted into gaseous forms, including nitrous oxide, a greenhouse gas that traps nearly 300 times as much heat in the atmosphere as carbon dioxide. About 70% of human-caused nitrous oxide comes from agricultural soils, so it’s vital to find ways to curb those emissions.

Study explores how food manufacturers respond to state regulations

When West Virginia recently banned seven artificial food dyes in products to be sold within their borders, they joined an increasing number of individual U.S. states issuing their own regulations about food manufacturing practices, allowable ingredients, or product labeling.

CABBI Team Deploys Robotic Lab to Revolutionize Plant Bioengineering

As the global population grows, the demand for food and energy is increasing even as extreme weather events make crops more vulnerable to stress. While traditional breeding takes years to develop more resilient crops, plant bioengineering offers a faster, more precise way to improve traits for higher yields and better stress tolerance.

But engineering plants to enhance their helpful traits is a complex process demanding significant time and labor.

Study: Microalgae and bacteria team up to convert CO2 into useful products

Scientists have spent decades genetically modifying the bacterium Escherichia coli and other microbes to convert carbon dioxide into useful biological products. Most methods require additional carbon sources, however, adding to the cost. A new study overcomes this limitation by combining the photosynthetic finesse of a single-celled algae with the production capabilities of the bacteria E. coli.

The researchers report their results in the journal Metabolic Engineering.

Parents’ advice benefits African American youth – when they seek support

Adolescence is a critical time for developing social skills and youth often navigate difficult peer experiences. Parents can help their children by giving advice on how to deal with challenges, but it matters whether youth want support or not.
