Summary: A new technique which involves fusing human and chimpanzee skin cells that have been modified to act like stem cells, allowed researchers to identify two novel genetic differences between humans and chimps.

One of the best ways to study human evolution is by comparing us with nonhuman species that, evolutionarily speaking, are closely related to us. That closeness can help scientists narrow down precisely what makes us human, but that scope is so narrow it can also be extremely hard to define. To address this complication, researchers from Stanford University have developed a new technique for comparing genetic differences.

Facebook is showing off its mind-reading wrist device and an augmented reality keyboard that it is working on as it prepares to release its smart glasses.

“The most spectacular result is the presence of strong jets, with speeds of up to 400 meters per second, which are located under the aurorae near the poles,” says Cavalié. These wind speeds, equivalent to about 1450 kilometers an hour, are more than twice the maximum storm speeds reached in Jupiter’s Great Red Spot and over three times the wind speed measured on Earth’s strongest tornadoes.

“Our detection indicates that these jets could behave like a giant vortex with a diameter of up to four times that of Earth, and some 900 kilometers in height,” explains co-author Bilal Benmahi, also of the Laboratoire d’Astrophysique de Bordeaux. “A vortex of this size would be a unique meteorological beast in our Solar System,” Cavalié adds.

Satellite imagery specialist Capella Space on Thursday released the first images captured by its two latest spacecraft launched in January.

The firm is trying to tap part of an Earth intelligence market it estimates is worth about $60 billion.

Capella’s business is based on combining a special type of imagery with a small, inexpensive spacecraft. The company is building a network of satellites that can capture images of places on Earth multiple times a day.

Master communicator Neil DeGrasse Tyson is at his inimitable self in this new episode. We discuss everything from why space aliens might have a whole other set of senses than we humans and why moving to Mars might never work. Please have a listen.

Astrophysicist Neil DeGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History (AMNH) in New York City, discusses everything from pond scum to space aliens in this off-the-wall and very engaging episode. It’s vintage Tyson. We also touch on his latest book written with George Mason University physicist James Trefil — “Cosmic Queries: StarTalk’s Guide To Who We Are, How We Got Here, And Where We’re Going.”

Just because a mathematical formula works does not mean it reflects reality.

These robots have nailed bottle-flipping, proving not even internet challenges are safe from automation.

A fundamental decision on a new station would be made by the end of this year, he said.

Rogozin said that current negotiations with NASA on the future of the ISS were “shallow”. He speculated that ISS’s life cycle would be repeatedly prolonged not by several years, but by one year. Also, he said it might be possible to extend the service life not of the whole station, but of its individual modules.

“On the sidelines of the April 9 launch we plan to hold technical consultations with NASA,” Rogozin said, adding there was a possibility of configuring the Lunar orbital platform Gateway for its possible docking with Russia’s new generation spacecraft Oryol.
