In the San Joaquin Valley, a lake emptied in the 19th century briefly returned, swallowing farmland, roads and power lines before retreating just as suddenly.
The San Joaquin Valley lake was drained about 130 years ago to create farmland.
Its return flooded roads, fields and power lines before the water quickly withdrew.
The event is tied to extreme rainfall and the land's underlying hydrological memory.
Three findings of the week: a space "airbag" against solar storms, a new theory on black holes, and research linking modern individualism to weakening emotional bonds.
An orbital magnetic shield could deflect solar storms and protect Earth's infrastructure.
Black holes may exist without a singularity at their core, new mathematical models suggest.
Modern individualism statistically reduces people's capacity for emotional attachment.
The Romanian scientist discovered the aerodynamic "Coandă effect" and contributed to early jet engine development — a legacy still present in physics textbooks worldwide.
Henri Coandă was born on 7 June 1886 and died in 1972, aged 86.
The Coandă effect describes fluid jet adhesion to curved surfaces, with broad technical applications.
Coandă also contributed to early jet engine research in the early 20th century.
Physicists at the University of Pittsburgh have shown that energy flow in turbulence can be deliberately reversed — opening new doors in climate science, oceanography, and medicine.
Pittsburgh researchers reversed the direction of energy flow inside a turbulent fluid.
The finding challenges a foundational fluid-physics theory established roughly 80 years ago.
Potential applications include climate modelling, ocean current control, and medical devices.
