Indigenous peoples have used forest thinning to protect against wildfires for millennia. These traditional methods – including cultural burning – have often been neglected in modern times, which is thought to have contributed to wildfires in the US and elsewhere. Now, researchers have shown for the first time in a regional hotspot for wildfire risk and drought risk that forest thinning with modern tools has an additional benefit: it increases the snowpack in winter by 16 to 30%, thus recovering lost water and helping to safeguard its supply for natural and human needs.

A new study by NYU chemists finds that DNA tiles can assemble into 3D structures without the sticky cohesion of hydrogen bonding. This finding, published in Nature Communications, turns a fundamental paradigm in the field of DNA self-assembly on its head.

Scientists have identified a new way to distinguish healthy guts from diseased ones and track how some illnesses progress by measuring how gut bacteria interact with one another.

According to a study published in Science, a collaboration between scientists at Rutgers University, Universidad de Granada in Spain and Princeton University found that healthy and diseased gut microbiomes behave like two distinct ecological states, driven not by individual microbes but by how entire bacterial communities compete and cooperate.

Scientists have published a review of what they’ve learned about moths and butterflies over the last few decades, with special attention given to pivotal moments that occurred during their ~300 million-year history.
