Could use magnetism to pull the iron back inside. O,.,o.

Earth’s molten core may be leaking iron, according to researchers who analyzed how iron behaves inside our planet.

The boundary between the liquid iron core and the rocky mantle is located some 1,800 miles (2,900 km) below Earth’s surface. At this transition, the temperature drops by more than a thousand degrees from the hotter core to the cooler mantle.

SAN FRANCISCO — German launch services provider Exolaunch announced plans April 14 to send multiple small satellites into orbit on a SpaceX Falcon 9 rideshare mission scheduled for December.

Exolaunch has integrated payloads and arranged launches for almost 100 satellites, but this is the company’s first launch services agreement with SpaceX, Exolaunch Commercial Director Jeanne Medvedeva told SpaceNews.

“Participation in SpaceX’s smallsat rideshare program will allow Exolaunch to offer reliable and cost efficient rideshare options out of the United States,” Medvedeva said by email. “Most of our customers have been proactively requesting such opportunities.”

Simple rules generating complicated networks may be how to build the universe.

Most of the pieces of Elon Musk’s Master Plan, Part Deux are already in place. Tesla’s mass-market cars, the Model 3 and Model Y, have already been released. The Solar Roof is finally seeing a ramp. And the release of a feature-complete version of the company’s Full Self-Driving suite seems to be drawing closer.

For Tesla’s Full Self-Driving suite to be feature-complete, the electric car maker would need to master inner-city driving. FSD already works for highway driving with Navigate on Autopilot with automatic lane changes. But when it comes to inner-city streets, Full Self-Driving still has some ways to go. Fortunately, if Tesla’s v10.2 2020.12.5 release is any indication, it appears that more and more aspects of city driving are becoming recognized by the company’s neural networks.

Mathematicians and neuroscientists have created the first anatomically accurate model that explains how vision is possible.

Students from Australia have unearthed a trove of rare treasures at a site in Israel and may have solved the mystery to King David’s long-lost city of Ziklag.

Strange particles observed by an experiment in Antarctica could be evidence of an alternative reality where everything is upside down.

A nightly jaunt on the exercise wheel enhances muscle-repair capabilities in old mice, according to a new study by researchers at Stanford School of Medicine.

Only older mice saw this benefit, which the researchers found is due to the rejuvenation of the animals’ muscle stem cells.

“The effect in old animals is very significant,” said Thomas Rando, MD, Ph.D., professor of neurology and neurological sciences and director of Stanford’s Glenn Center for the Biology of Aging. “We found that regular exercise restores youthfulness to tissue repair. Their muscle stem cells start to look and behave like those of much younger animals.”
