Fetal brain impacted when mom fights severe flu: New mouse study explains how

New research using live mouse-adapted influenza virus improves upon previous mouse experiments to explain how maternal infection impacts fetal brain development. The study also indicates fetal brain changes are more likely once the severity of the mother's infection meets a specific threshold.

New additive process can make better -- and greener -- high-value chemicals

Researchers have achieved a significant breakthrough that could lead to better -- and greener -- agricultural chemicals and everyday products. Using a process that combines natural enzymes and light, the team developed an eco-friendly way to precisely mix fluorine, an important additive, into chemicals called olefins -- hydrocarbons used in a vast array of products, from detergents to fuels to medicines. This groundbreaking method offers an efficient new strategy for creating high-value chemicals with potential applications in agrochemicals, pharmaceuticals, renewable fuels, and more.

'Dancing molecules' heal cartilage damage

New therapy uses synthetic nanofibers to mimic the natural signaling of a protein that is crucial for cartilage formation and maintenance. Researchers found that intensifying the motion of molecules within the nanofibers led to more components needed for regeneration. After just four hours, the treatment activated the gene expression necessary to generate cartilage. Therapy could be used to treat osteoarthritis, which affects nearly 530 million people worldwide.

New understanding of fly behavior has potential application in robotics, public safety

Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out of a moving car? Flies aren't just reacting to an odor with a preprogrammed response: they are responding in context-appropriate manner. This knowledge potentially could be applied to train more sophisticated algorithms for scent-detecting drones to find the source of chemical leaks.
