Body movement is achieved by molecular motors. A new ‘molecular nano-patterning’ technique allows us to study these motors, reveals that some motors coordinate differently

Body movement, from the muscles in your arms to the neurons transporting those signals to your brain, relies on a massive collection of proteins called molecular motors. Fundamentally, molecular motors are proteins that convert chemical energy into mechanical movement, and have different functions depending on their task. However, because they are so small, the exact Read more about Body movement is achieved by molecular motors. A new ‘molecular nano-patterning’ technique allows us to study these motors, reveals that some motors coordinate differently[…]

Turns out that RNA affects DNA in multiple ways. Genes don’t just send messages to RNA which then direct proteins to do stuff.

Rather than directions going one-way from DNA to RNA to proteins, the latest study shows that RNA itself modulates how DNA is transcribed—using a chemical process that is increasingly apparent to be vital to biology. The discovery has significant implications for our understanding of human disease and drug design. […] The picture many of us Read more about Turns out that RNA affects DNA in multiple ways. Genes don’t just send messages to RNA which then direct proteins to do stuff.[…]
