Scientists identify a six-year cycle of super-and sub-rotation that affected the length of a day based on their analysis of seismic data.

Earth’s structure is divided into layers, with the inner core at the center followed by the outer core, lower mantle, upper mantle, crust, and atmosphere. The inner core is the hottest part of the planet at about 10,000 °F (5400 °C), which is similar to the temperature of the surface of the sun!

Believed to consist mostly of an iron-nickel alloy.

Next up in our series exploring deconstructivist architecture we look at Gehry House, architect Frank Gehry’s radical extension to his home in California.

“If something drastic doesn’t change in the next few weeks/months, I promise you, you’ll see empty shelves everywhere you look,” Smith wrote in a post that was shared nearly 290,000 times. “You’ll see chaos as people fight for the basic necessities of everyday life.”

Smith did not respond to a request for comment from Insider in time for publication.

Insider spoke with five truckers who warned that the industry could be at a breaking point. The drivers say they’ve had to get creative in recent months as they work to turn a profit while spending thousands at the pump.

When moving furniture, heavy objects are easier to move if you rotate them while pushing. Many people intuitively do this. An international research team from Konstanz (Germany), Trieste and Milan (Italy) has now investigated on the microscopic scale the reduction in static friction caused by simultaneous rotation.

In their recent study, to be published in Physical Review X on June 15, the researchers found that the reduction in static friction of a microscopic object on a crystalline surface can be described by moiré patterns, which occur when periodic patterns superimpose. Based on this concept, the researchers predict an unusual state, in which microscopic objects can be set in rotation by applying a minimal amount of torque. In the future, this could enable the construction of micro-machines with ultra-low static friction against rotation.

A new science fiction novel does a masterful job of crafting a narrative from an idea long discussed in philosophy: Is the mind needed?
