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.

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.

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.

AI is changing the way we work, create, and share information — but brownies?

The success of in vitro fertilization depends on many factors, one of which is sperm viability.

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.

Up to 25% of new mothers suffer from postpartum depression, which can significantly impact their parenting behavior and the wellbeing of their children.

A nine-year study comparing a typical two-year corn and soybean rotation with a more intensive three-year rotation involving corn, cereal rye, soybean and winter wheat found that the three-year system can dramatically reduce nitrogen — an important crop nutrient — in farm runoff without compromising yield.

The new findings are detailed in the journal Frontiers in Environmental Science.

The physical structure of corn plants — including the angle of leaves bending from the stem and the number of pollen-laden tassel branches — makes a big difference for yield. Compact plants can be planted closer together, adding up to more ears per acre. But compact corn didn’t happen by accident; years of hybrid breeding did that. Now, two new genome-based studies are making it possible to precisely adjust corn architecture to meet future demands.

Nanozymes are synthetic materials that have enzyme-like catalytic properties, and they are broadly used for biomedical purposes, such as disease diagnostics. However, inorganic nanozymes are generally toxic, expensive, and complicated to produce, making them unsuitable for the agricultural and food industries.
