Scientists were wrong for decades about DNA knots

Scientists at the University of Cambridge, working with international collaborators, have identified a crucial process that shapes how DNA behaves as it moves through nanoscale pores. This process is fundamental to many biological activities and to fast-growing DNA sensing technologies. The research highlights a long-overlooked DNA structure called plectonemes, a…

Forests are changing fast and scientists are deeply concerned

Trees are essential to life on Earth. They absorb and store CO2, support animals, fungi, and insects, hold soil in place, manage water cycles, and provide people with vital resources such as wood, food, and cooling shade during hot weather. Despite their importance, forests around the world are undergoing a…

Why this rust-like mineral is one of Earth’s best carbon vaults

Scientists have known for years that iron oxide minerals help store vast amounts of carbon by keeping it out of the atmosphere. A new study from Northwestern University now explains the chemistry behind that ability, revealing why these minerals are especially effective at locking carbon in place. By closely examining…
