Zero-Covid harming 75% of European firms in China: business group

Beijing (AFP) Sept 21, 2022 - China's inflexible and inconsistent zero-Covid policy is crippling European business operations in the country, a major business lobby said Wednesday, warning that the presence of the companies can no longer be taken for granted.

Outer Planets

Titan's methane should have been stripped away by sunlight within tens of millions of years — the fact that it persists after four billion years means something, possibly ice volcanoes venting from the interior, is still replenishing it, and no one yet knows what

Sunlight should remove Titan's methane on a geological blink. Cryovolcanism may refill the atmosphere, but Cassini never caught an eruption and the source remains unknown.

Water World

What happened when engineers removed a century-old hydroelectric dam from a New England river, and Atlantic salmon returned to spawning grounds they had not reached in roughly 200 years?

On the Kennebec River in central Maine, excavators cut into the Edwards Dam on 1 July 1999, and the impoundment behind it began to drain…

Outer Planets

On Titan, Saturn's largest moon, water is the bedrock — frozen to minus 179 degrees and harder than granite — and the rain, rivers and seas that run over it are not water at all but liquid methane, exactly as it comes out of a gas pipe

Titan’s familiar-looking weather is built from reversed materials: water ice forms the landscape while methane cycles through clouds, rain, rivers, lakes and seas.

Earth Observation

How does a soft-bodied ocean animal with no bones and no central command run its eight limbs semi-independently, keeping roughly two-thirds of its half-billion neurons out in the arms themselves?

About two-thirds of an octopus's roughly 500 million neurons sit in its arms, not its brain. A 2025 University of Chicago study in Nature Communications explains why: each axial nerve cord is segmented like a corrugated pipe, with local circuits controlling sucker movement and building a topographical map of the arm.

The SR-71 Blackbird cruised at Mach 3.2 above 25,000 metres, and its titanium skin ran so hot in flight that the fuselage grew about 10 centimetres longer, which is why the fuel tanks were designed to leak on the ground and only seal once the plane heated up in the air

The SR-71 Blackbird's titanium airframe grew several inches longer at Mach 3.2 as skin temperatures passed 300°C, which is why Lockheed engineers designed the fuel tanks to leak on the ground and seal only in flight.
