Some neural nets can work well using both bits and qubits.

The researchers used human stem cells to create a model of early brain development — organoids.

An international team of scientists has uncovered the vital role of microglia, the immune cells in the brain that acts as its dedicated defense team, in early human brain development.

Experts have searched for decades for a polygon that only makes non-repeating patterns. But no one knew it was possible until now.

Space fans, get ready to start your moon engines.

NASA’s Artemis 1 uncrewed moon mission lifted off from NASA’s Kennedy Space Center (KSC) in Florida on Nov. 16, 2022. One year later, the next moon rocket ride for astronauts is in testing for a new mission that could launch in late 2024.

United Launch Alliance has its missing rocket piece in hand at Cape Canaveral and all systems are go for a Christmas Eve launch to mark the debut of its Vulcan Centaur rocket.

A new Centaur upper stage arrived by barge to the Space Coast on Monday, a replacement for the stage ULA originally planned to fly on the Certification-1 mission this past May. That initial flight, already delayed for nearly two years, was again put on hold after an issue with a test version of the Centaur stage was destroyed amid a massive fireball in the spring, requiring design changes to ensure a repeat didn’t happen during actual liftoff.

“The path to flight 1 is clear,” said ULA President and CEO Tory Bruno. “All we need to do is integrate the stage onto the vehicle. We do all kinds of system testing anytime we touch it, so we’ll have to pass all of that, get through the [wet dress rehearsal] and then integrate the payload, and off to space,”

SpaceX delayed its second test flight of a Starship rocket and Super Heavy booster to no earlier than Saturday (Nov. 18), to replace a rocket part.

The Great Resignation may be over for most workers — but for some top honchos, it’s only just begun.

The number of chief executive resignations this year hit a record high, according to a recent report by Challenger, Gray and Christmas Inc.

Over 1,400 CEOs have stepped down from their positions between January to September, marking an almost 50% rise from the 969 departures over the same period last year. The career consultancy firm noted that the figure is the highest since it started compiling data in 2002.

The machine-learning model takes less than a minute to predict future weather worldwide more precisely than other approaches.
