Northern spotted owl once became a symbol of America’s logging wars; now scientists say it is already functionally extinct

The northern spotted owl, once a revered icon of environmental activism, faces dire circumstances as it becomes functionally extinct in numerous regions. A recent study indicates a severe decline in its populations throughout their historical habitat. Factors such as habitat destruction and rampant wildfires have severely impacted the species over the years, while the encroaching barred owl emerges as a formidable threat.

Chicago physicist’s 20-year-old quantum imaging theory gets experimental proof using superconductors

The University of Illinois Chicago’s Dirk Morr proposed a way to create high-resolution quantum images using superconductors two decades ago. A new experiment by researchers in Germany, supported by Morr’s theoretical model, has now produced quantum imaging similar to what he predicted, providing experimental confirmation of his earlier work.

NASA tests GPS-free navigation using other satellites and space debris as landmarks

NASA has tested FALCON, a system that lets satellites navigate without GPS by using other spacecraft and orbital debris as reference points. During a three-day test, the system autonomously improved the known orbits of more than 200 space objects while also calculating the position of NASA’s Starling spacecraft.

Three forgotten kings may change the accepted timeline of ancient Assyria

Research indicates that ancient Assyrian king lists could have neglected to mention several ephemeral rulers. Evidence points to three monarchs who temporarily ascended the throne amid turbulent political times. Their short reigns might have been intentionally omitted from the official historical timeline, raising questions about the accuracy of Assyria's established chronology.
