Artificial intelligence helped co-pilot a U-2 “Dragon Lady” spy plane during a test flight Tuesday, the first time artificial intelligence has been used in such a way aboard a US military aircraft.

Mastering artificial intelligence or “AI” is increasingly seen as critical to the future of warfare and Air Force officials said Tuesday’s training flight represented a major milestone.

“The Air Force flew artificial intelligence as a working aircrew member onboard a military aircraft for the first time, December 15,” the Air Force said in a statement, saying the flight signaled “a major leap forward for national defense in the digital age.”

Astronomers may have found a “Planet Nine,” but in another solar system. Will we eventually find the hypothetical Planet Nine in our own Solar System?

Even with all we’ve learned about our own Solar System, especially in the last couple of decades, researchers still face many unanswered questions. One of those questions regards the so-called Planet Nine. The Planet Nine hypothesis states that there’s a massive planet in our Solar System orbiting at a great distance from the Sun.

Nobody’s ever observed the hypothesized planet; the evidence for it lies in a cluster of bodies that orbit the Sun 250 times further out than Earth does. These objects are called e-TNOs, for extreme Trans-Neptunian Objects. According to the hypothesis, Planet Nine’s gravity is responsible for the unusual clustered orbits of these e-TNOs.

Summary: YKL-40 may be a key player in circadian rhythm disruptions associated with Alzheimer’s disease.

Fractured sleep, daytime sleepiness and other signs of disturbance in one’s circadian rhythm are common complaints of people with Alzheimer’s disease, and the problems only get worse as the disease progresses. But the reason for the link between Alzheimer’s and circadian dysfunction is not well understood.

Anyone who has ever worked on a team knows that their strength lies in coordination and a shared vision. However, it is not always easy to provide that coordination and shared vision, and any team that lacks that cohesiveness becomes more of a hindrance than a help.

Science is not immune to the difficulties of running effective teams. There is plenty to be gained from more coordination between differing silos and physical locations. Recently a meeting in Chile prompted a group of scientists to propose a plan to change that. The result is a white paper that points out the potential benefits of coordinating ground, orbital and in situ based observations of objects. But more importantly, it suggests a different path forward where all of the space science community can benefit from the type of coordinated output that can only come from a cohesive team.

The suggested path laid out in the white paper began at the Planets2020 conference in Chile, hosted by the ALMA observatory. The meeting took place back in March, right before the Coronavirus outbreak began to restrict travel. At the conference, there was a significant amount of discussion focused on the capabilities of different Earth and space based observing platforms. The intention was to learn more about missions that coordinated ground and space-based observations, and to flesh out future ideas of how to replicate that coordination with new and existing platforms to make the best of their different capabilities. The lead author of the white paper, Vincent Kofman, a research chemist at Goddard Space Flight Center, took on that the task of coordinating that team and produced a paper that clearly lays out a better way to perform observations.

Summary: When convolutional neural networks are trained under experimental conditions, they are deceived by the brightness and color of a visual image in similar ways to the human visual system.

A convolutional neural network is a type of artificial neural network in which the neurons are organized into receptive fields in a very similar way to neurons in the visual cortex of a biological brain.

Summary: A new AI model mimics how the prefrontal cortex uses gating to control information flow between different areas of neurons. The system could help in the development of new artificial intelligence technologies that better mimic the human brain.

Getting computers to “think” like humans is the holy grail of artificial intelligence, but human brains turn out to be tough acts to follow. The human brain is a master of applying previously learned knowledge to new situations and constantly refining what’s been learned. This ability to be adaptive has been hard to replicate in machines.

Johnson & Johnson said Thursday that late-stage clinical trials for its coronavirus vaccine are now fully enrolled, and expects to release initial data on the shot’s effectiveness by the end of January.

The pharmaceutical company’s single-dose vaccine is in Phase 3 clinical trials that are now fully enrolled, and is already being reviewed by Health Canada.

Sit! Stay! Fetch! Map a Martian cave!

Robotic “Mars Dogs” could use artificial intelligence and sensors to investigate the Martian surface and map hidden lava tunnels.

Electric vehicle start-up Canoo unveiled a new delivery van Thursday ahead of its public debut on the Nasdaq next week.

The futuristic-looking van — known as a multi-purpose delivery vehicle, or MPDV, because of the ways it can be upfitted — is designed for everything from last-mile deliveries to food trucks, according to the California company. It is expected to start at around $33, 000.

“There are many use cases that this vehicle can do,” Canoo Chairman Tony Aquila, a major investor in the company, said during a video unveiling of the MPDV. “We wanted it to look very smart, very modern but at the same time be very affordable.”
