Amyloids are perhaps best known as a key driver of Alzheimer's disease. The amorphous proteins, found throughout the human body, stick to nerve cells like plaque, choking off their function and ...

Penn State scientists uncovered an ancient bacterial defense where dormant viral DNA helps bacteria fight new viral threats. The enzyme PinQ flips bacterial genes to create protective proteins that ...

Bacteria come in all shapes and sizes -- some are straight as a rod, others twist like a corkscrew. Shape plays an important role in how bacteria infiltrate and attack cells in the body. The helical ...

Scientists didn’t understand how bacteria divide up carbon sources into different paths for energy or to build new materials. Professor Ludmilla Aristilde; Professor Niall Mangan; Postdoctoral ...
