Researchers show which signaling pathways make plants more resistant to flooding. The molecule ethylene is a warning signal for plants that they are under water and switches on the emergency supply for survival without oxygen. A team shows that plants can survive longer without oxygen when pretreated with ethylene.
Despite dire warnings, monarch butterfly numbers are solid
Scientists have been warning for quite some time that monarch butterflies were slated for extinction due to diminishing winter colonies. But a new study found that warming temperatures and growth in the summer population of monarchs has compensated for losses during the winter. Researchers did preach continued caution, as the...

Portland State Study Shows How ‘Green Islands’ Help Forests Regenerate After Fire
Thanks to climate change, high-elevation forests in the Central Cascade mountains of the Pacific Northwest are burning more frequently and expansively than in the recent past, prompting researchers and fire managers to question whether forests will be able to recover from these emerging fire patterns and whether they will require...
Pre-historic Wallacea: A melting pot of human genetic ancestries
The Wallacean islands of present-day Eastern Indonesia have a long history of occupation by modern humans. Notably, the maritime expansion of Austronesian speakers into Wallacea left archaeological traces of a Neolithic lifestyle and a genetic imprint still detectable in Eastern Indonesians today. To gain further insights into Wallacea's settlement history,...
