A new database of weeds that can help scientists understand how traditional agricultural systems were managed throughout history, could also provide insights into how global trends like the climate crisis could affect the resilience of our modern day food systems.

The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.

Early in 2023, a series of storms dumped record-breaking amounts of rain and snow across California.
