Research has long strived to develop computers to work as energy efficiently as our brains. A study, led by researchers at the University of Gothenburg, has succeeded for the first time in combining a memory function with a calculation function in the same component. The discovery opens the way for more efficient technologies, everything from mobile phones to self-driving cars.

In recent years, computers have been able to tackle advanced cognitive tasks, like language and image recognition or displaying superhuman chess skills, thanks in large part to artificial intelligence (AI). At the same time, the is still unmatched in its ability to perform tasks effectively and energy efficiently.

“Finding new ways of performing calculations that resemble the brain’s energy-efficient processes has been a major goal of research for decades. Cognitive tasks, like image and voice recognition, require significant computer power, and mobile applications, in particular, like mobile phones, drones and satellites, require energy efficient solutions,” says Johan Åkerman, professor of applied spintronics at the University of Gothenburg.

For scanning underground structures and caves. Maybe scanning buildings, and doing security stuff, but doors would be a problem. Also too loud, but would be a nice start point for an Ion Drive flight system.

Looking like a micro-sized version of the Death Star, the Dronut X1, which Boston-based start-up Cleo Robotics released for commercial use earlier this month, is the first professional-grade bi-rotor ducted-fan drone – a drone without exposed rotor blades – built to conduct inspections in close-quartered and hazardous environments.

Its unique design, featuring hidden propellers and rounded form, means the Dronut is collision-tolerant and can be operated near sensitive equipment, Cleo Robotics’ CEO and co-founder Omar Eleryan said in an interview.

SpaceX’s newest drone ship is on its way out into the Atlantic Ocean for a Starlink mission that will break the company’s record for annual launch cadence.

Somewhat confusing known as Starlink Shell 4 Launch 3 or Starlink 4–3, the batch of 53 laser-linked V1.5 satellites is scheduled to fly before Starlink 4–2 for unknown reasons and at the same time as Starlink 2–3 is scheduled to fly before Starlink 2–2 on the West Coast. Regardless of the seemingly unstable launch order, perhaps related to the recent introduction of Starlink’s new V1.5 satellite design, drone ship A Shortfall of Gravitas’ (ASOG) November 27th Port Canaveral confirms that SpaceX is more or less on track to launch Starlink 4–3 no earlier than (NET) 6:20 pm EST (23:20 UTC) on Wednesday, December 1st.

In a bit of a return to stride after launching 20 times in the first six months but only three times in the entire third quarter of 2021, Starlink 4–3 is currently the first of four or even five SpaceX launches scheduled in the last month of the year. Nevertheless, if Starlink 4–3 is successful, it will also set SpaceX up to cross a milestone unprecedented in the history of satellite launches.

Substantially extending the strike range of fighter jets.

Boeing’s unmanned air tanker MQ-25 Stingray is currently completing ground tests at the Naval Station Norfolk in Virginia in preparation for a carrier demonstration, the U.S. Navy confirmed in a press release.

Unveiled over three years ago, the MQ-25 or T1 tanker is designed to refuel naval fighter aircraft mid-air. Although mid-air refueling is common practice for the U.S. military, this is the first attempt with an unmanned drone. The MQ-25 has been making rapid strides since its unveiling and has successfully completed a refueling attempt of the F-35C aircraft in September this year.

The drone tanker is now moving a step closer to deployment. According to the press release, the U.S. Navy and Boeing are moving through ground tests currently and aiming for a carrier demonstration in December. As part of the tests, the team recently completed deck handling where the engines on the aircraft were up and running and the taxiing was handled by controllers on the deck.

Walmart has launched an instant drone delivery system for customers living within a 50-mile radius of its headquarters in northern Arkansas.

The retail giant has partnered with drone company Zipline to launch the new system that will offer on-demand delivery for health and wellness and consumable items within 50 miles of the Walmart Neighborhood Market in Pea Ridge, according to a press release.

“It’s unbelievably exciting, we’ve been working towards this day for many many years,” Zipline’s CEO Liam O’Connor told CBS News.

It’s a cool concept; the blades cant get caught, or stuck, or broken. but, it’s pretty loud, there’s no audio in the demo videos. Still, i think a flying drone would be superior for exploring underground structurers and caves, til it hit a door or something anyways. Anyhow, i think the flight system should focus on some kind of a total silence ion drive.


It was three years ago that we first heard about the Cleo, a robust, donut-shaped prototype drone made by Cleo Robotics. Well, its successor is now commercially available, under the new (and apt) name of the Dronut X1.

Like its predecessor, the Dronut X1 features just two counter-rotating rotors stacked one above the other. While we have seen other drones that take this approach, Cleo Robotics goes the extra step of enclosing those rotors within a composite ducted body. This means that they can’t harm bystanders, nor can they be harmed when bumping into obstacles such as walls.

SpaceX has aced its first operational interplanetary launch, sending NASA’s Double Asteroid Redirection Test (DART) spacecraft on its way out of the Earth-Moon system as part of the world’s first planetary defense mission.

Right on time, SpaceX’s flight-proven Falcon 9 booster lifted off at 10:21 pm PST with an expendable upper stage, new fairing, and the ~630 kg (~1400 lb) DART spacecraft in tow, reaching a nominal low Earth parking orbit about eight minutes later. A few seconds after the second stage’s first engine cutoff (SECO-1), booster B1063 safely landed on drone ship Of Course I Still Love You (OCISLY), wrapping up its third orbital-class launch and spaceflight in twelve months.

Around 28 minutes after liftoff, Falcon 9’s orbital second stage fired up for the second and final time. In just 53 seconds, Falcon 9’s upper stage accelerated from a stable velocity (relative to Earth’s surface) of 7.5 kilometers per second (4.7 mi/s) to almost 11.1 km/s (6.9 mi/s), sending DART (and itself) from low Earth orbit (LEO) to an Earth escape trajectory that will ultimately leave them in orbit around the sun.

Move over, Hollywood—science fiction is getting ready to leap off the big screen and enter the real world. While recent science fiction movies have demonstrated the power of artificially intelligent computer programs, such as the fictional character J.A.R.V.I.S. in the Avenger film series, to make independent decisions to carry out a set of actions, these imagined movie scenarios could now be closer to becoming a reality.

In a recent study published in Nature Communications, a journal of Nature, researchers at the University of Missouri and University of Chicago have developed an , called a metamaterial, which can respond to its environment, independently make a decision, and perform an action not directed by a human being. For example, a drone making a delivery might evaluate its environment including , speed or wildlife, and automatically change course in order to complete the delivery safely.

Guoliang Huang, Huber and Helen Croft Chair in Engineering, and co-author on the study, said the mechanical design of their new artificial material incorporates three main functions also displayed by materials found in nature—sensing; information processing; and actuation, or movement.

Get ready for the ‘White Bat’.

What’s the best way to counter gossip? Coming out with the truth. That seems to be the idea behind a new video released by the U.S. Air Force’s Profession of Arms Center of Excellence (PACE).

The video that was released earlier this month recounts the ways intelligence gathering, surveillance, and reconnaissance (ISR) have improved over the decades. The U.S. has moved far ahead from the days when balloons were sent up in the air to understand what was happening behind enemy lines. Adversaries of the U.S. are now a world away and the military still has the ability to “find the unfindable.”
