#Salar de Uyuni’s #Mirror effect is not uniform, but varies with rainfall and evaporation. The most reflective conditions occur after heavy rain, with peak visibility from late January to early March. @NaturePortfolio https://t.co/IrWXcv2VPX https://t.co/zKoVmV4HBN

#A rare hybrid bird, the offspring of a green jay and a blue jay, has been identified in Texas, likely resulting from overlapping ranges driven by recent climate shifts. @utaustin https://t.co/85N8OHCFf3 https://t.co/42EVhOfSVz

Cecilia Payne-Gaposchkin was just 25 years old when she discovered what stars are made of: hydrogen, helium and just a dash of nearly every other element.

The subatomic particles called neutrinos are famously elusive. But an unconventional trick could make a laser beam of the aloof particles.

#Earth’s early composition lacked key #VolatileElements for life. Evidence indicates a later collision with a distant, water-rich body likely delivered these essentials, enabling Earth’s habitability. @ScienceAdvances https://t.co/BmZmyo2AGA https://t.co/2gidJhCxxf

The first quantum computer in space is now orbiting Earth on a satellite, scientists report. Launched on June 23, the computer had to be designed to fit in a small package, use limited power and endure wild temperature swings.

The Fed has paid $188B to banks NOT to loan money, 40% of that is going to foreign banks. It’s losing money while micromanaging rates. I explained why it’s time to rethink the entire system with @LarryKudlow.
