A volcano erased an island’s plants. Their DNA revealed how life starts over

Scientists have determined the genetic lineage of a now extinct plant population from Nishinoshima, a volcanic island whose frequent eruptions periodically "reset" the vegetation. While they traced the lineage to a nearby island, they discovered distinct genetic quirks due to…

Image: Using data from known protein structures and sequences, scientists developed an artificial intelligence (AI) workflow to predict the structures and functions of unknown proteins, including how these proteins would interact with metals such as zinc. In this example, predicted to be a zinc-binding protein, the model of the protein shows that four cysteine residues are directly involved in the interaction with zinc.

How do plants recover after drought?

A plant’s number one priority is to grow—a feat that demands sunlight, nutrients, and water. If just one of these three inputs is missing, like water in a drought, growth halts. You might then think that at the end of that…
