Rescue crews airlift hundreds out of rural Alaskan villages after powerful storm
YouTube video by PBS NewsHour Rescue crews airlift hundreds out of rural Alaskan villages after powerful storm

This is good reporting on the disaster in Alaska if you're looking for a reliable summary.

This is a bigger disaster than I think most are realizing. 1500 people have been displaced by the flooding with an exceptionally complicated response and recovery.

Orwell’s opposition to totalitarianism was rooted in his support for freeing workers from poverty and exploitation George Orwell, the author of two classic anti-totalitarian, pro-freedom novels from the 1940s, was a democratic socialist who opposed authoritarian leaders of the left and the right.

Orwell’s opposition to totalitarianism was rooted in his support for freeing workers from poverty and exploitation... and his earlier writings show how his convictions were formed and evolved.

Archaeologists are unearthing the most powerful women who ever lived Astonishing new archaeological finds and ancient DNA analysis leave no doubt that throughout prehistory women were rulers, warriors, hunters and shamans

Astonishing discoveries by archaeologists and analysis of ancient genomes mean we must rethink the emergence of patriarchy and the roles of women in prehistoric societies.
