United Airlines Wants to Bring Back Supersonic Air Travel
Lauren Hirsch | The New York Times
“…United Airlines said it was ordering 15 jets that can travel faster than the speed of sound from Boom Supersonic, a start-up in Denver. …Boom, which has raised $270 million from venture capital firms and other investors, said it planned to introduce aircraft in 2025 and start flight tests in 2026. It expects the plane, which it calls the Overture, to carry passengers before the end of the decade.”

SPACE
Spacex Signs ‘Blockbuster Deal’ To Send Space Tourists to the ISS
Amanda Kooser | CNET
“On Wednesday, space tourism company Axiom Space announced a ‘blockbuster deal’ with SpaceX that will send private crews to the ISS through 2023. Axiom and SpaceX already had a deal in place for a Dragon spacecraft flight with three private citizens and former NASA astronaut Michael López-Alegría in early 2022. The new agreement expands the scope to a total of four flights.”

TRANSPORTATION
Why Electric Cars Will Take Over Sooner Than You Think
Justin Rowlatt | BBC News
“This isn’t a fad, this isn’t greenwashing. Yes, the fact many governments around the world are setting targets to ban the sale of petrol and diesel vehicles gives impetus to the process. But what makes the end of the internal combustion engine inevitable is a technological revolution. And technological revolutions tend to happen very quickly.”

ETHICS
Have Autonomous Robots Started Killing in War?
James Vincent | The Verge
“…over the past week, a number of publications tentatively declared, based on a UN report from the Libyan civil war, that killer robots may have hunted down humans autonomously for the first time. As one headline put it: ‘The Age of Autonomous Killer Robots May Already Be Here.’ But is it? As you might guess, it’s a hard question to answer.”

ENERGY
Chart: Behind the Three-Decade Collapse of Lithium-Ion Battery Costs
Rahul Rao | IEEE Spectrum
“Between 1991 and 2018, the average price of the batteries that power mobile phones, fuel electric cars, and underpin green energy storage fell more than thirtyfold, according to work by Micah Ziegler Jessika Trancik and at the Massachusetts Institute of Technology. …Batteries today, the researchers say, have mass-production scales and energy densities unthinkable 30 years ago.”

HEALTH
The UK Has a Plan for a New ‘Pandemic Radar’ System
Maryn McKenna | Wired
“i‘What we really need is a broadly distributed, high-fidelity, always-on surveillance system…’ says Samuel V. Scarpino, an assistant professor at Northeastern University who directs its Emergent Epidemics Lab. ‘This is not something that can be built easily. But we have a narrow window right now, where basically the whole planet knows that we need to solve this.’i”

INTERFACES
Vilnius, Lithuania Built a ‘Portal’ to Another City To Help Keep People Connected
Kim Lyons | The Verge
“They really went all-in on the idea and the design; it looks quite a bit like something out of the erstwhile sci-fi movie/show Stargate. …The portals both have large screens and cameras that broadcast live images between the two cities—a kind of digital bridge, according to its creators—meant to encourage people to ‘rethink the meaning of unity,’ Go Vilnius said in a press release. Aw.”

SECURITY
Amazon Devices Will Soon Automatically Share Your Internet With Neighbors
Dan Goodin | Ars Technica
“Amazon’s experimental wireless mesh networking turns users into guinea pigs. …By default, a variety of Amazon devices will enroll in the system come June 8. And since only a tiny fraction of people take the time to change default settings, that means millions of people will be co-opted into the program whether they know anything about it or not.”

#439263 Somehow This Robot Sticks to Ceilings by ...

Just when I think I’ve seen every possible iteration of climbing robot, someone comes up with a new way of getting robots to stick to things. The latest technique comes from the Bioinspired Robotics and Design Lab at UCSD, where they’ve managed to get a robot to stick to smooth surfaces using a vibrating motor attached to a flexible disk. How the heck does it work?

According to a paper just published in Advanced Intelligent Systems, it’s due to “the fluid mediated adhesive force between an oscillatory plate and a surface” rather than black magic. Obviously.

Weird, right? In the paper, the researchers explain that what’s going on here: As the 14cm diameter flexible disk vibrates at 200 Hz, it generates a thin layer of low pressure air in between itself and the surface that it’s vibrating against. Although the layer of low pressure air is less than 1 mm thick, the disk can resist 5 N of force pulling on it. You can sort of think of this as a suction effect, except that it doesn’t require the disk to be constantly sealed against a surface, meaning that the robot can move around without breaking adhesion.

The big advantage here is that this is about as simple and cheap as a smooth-surface climbing robot gets, especially at small(ish) scales. There are a couple of downsides too, though. The biggest one could be that 200 Hz is a frequency that’s well within human hearing, which probably explains that soundtrack in the video—the robot is, as the researchers put it, “inherently quite noisy.” And in contrast to some other controllable adhesion techniques, this system must be turned on at all times or it will immediately plunge to its doom.

The robot you’re looking at in the video (with a 14cm disk) seems to be the sweet spot when it comes to size—going smaller means that the motor starts taking up a disproportionate amount of weight, while going larger would likely not scale well either, with the overall system mass increasing faster than the amount of adhesion that you get. The researchers suggest that “it could be advantageous to combine several disk geometries to achieve the desired load capacity and resilience to disturbances,” but that’s one of a number of things that the researchers need to figure out to properly characterize this novel adhesion technique.

Gas-Lubricated Vibration-Based Adhesion for Robotics, by William P. Weston-Dawkes, Iman Adibnazari, Yi-Wen Hu, Michael Everman, Nick Gravish, and Michael T. Tolley, is available here. Continue reading

COMPUTING
A New Brain Implant Translates Thoughts of Writing Into Text
John Timmer | Wired
“In early experiments, a paralyzed man with implants in his premotor cortex typed 90 characters per minute—by envisioning he was writing by hand. …[This easily topped] the previous record for implant-driven typing, which was about 25 characters per minute. The raw error rate was about 5 percent, and applying a system like a typing autocorrect could drop the error rate down to 1 percent.”

VIRTUAL REALITY
Grand Theft Auto Looks Frighteningly Photorealistic With This Machine Learning Technique
Andrew Liszewski | Gizmodo
“What’s even more impressive is that the researchers think, with the right hardware and further optimization, the gameplay footage could be enhanced by their convolutional network at ‘interactive rates’—another way to say in real-time—when baked into a video game’s rendering engine. So instead of needing a $2,000 PS6 for games to look like this, all that may be needed is a software update.”

INTERFACES
Better Than Holograms: 3D-Animated Starships Can Be Viewed From Any Angle
Jennifer Oullette | Ars Technica
“The technology making this science fiction a potential reality is known as an optical trap display (OTD). These are not holograms; they’re volumetric images, as they can be viewed from any angle, as they seem to float in the air.”

NEUROSCIENCE
Genes Linked to Self-Awareness in Modern Humans Were Less Common in Neanderthals
Emily Willingham | Scientific American
“Our creative powers may explain why we have been around for the past 40,000 years and Neanderthals have not. Also, traits that stand out in modern humans may provide clues as to why we have maneuvered a helicopter on Mars while chimpanzees have only engaged in the most basic tool use.”

FUTURE
The Profound Potential of Elon Musk’s New Rocket
Robert Zubrin | Nautilus
“Starship won’t just give us the ability to send human explorers to Mars, the moon, and other destinations in the inner solar system, it offers us a two-order-of-magnitude increase in overall operational capability to do pretty much anything we want to do in space.”

ARTIFICIAL INTELLIGENCE
The Pentagon Inches Toward Letting AI Control Weapons
Will Knight | Wired
“The drill was one of several conducted last summer to test how artificial intelligence could help expand the use of automation in military systems, including in scenarios that are too complex and fast-moving for humans to make every critical decision. The demonstrations also reflect a subtle shift in the Pentagon’s thinking about autonomous weapons, as it becomes clearer that machines can outperform humans at parsing complex situations or operating at high speed.”

TECHNOLOGY
Smartphone Is Now ‘the Place Where We Live’, Anthropologists Say
Alex Hern | The Guardian
“i‘The smartphone is perhaps the first object to challenge the house itself (and possibly also the workplace) in terms of the amount of time we dwell in it while awake,’ they conclude, coining the term ‘transportal home’ to describe the effect. ‘We are always “at home” in our smartphone. We have become human snails carrying our home in our pockets.”

SCIENCE
Extraterrestrial Plutonium Atoms Turn up on Ocean Bottom
William J. Broad | The New York Times
“Scientists studying a sample of oceanic crust retrieved from the Pacific seabed nearly a mile down have discovered traces of a rare isotope of plutonium, the deadly element that has been central to the atomic age. They say it was made in colliding stars and later rained down through Earth’s atmosphere as cosmic dust millions of years ago.”

The Robot Surgeon Will See You Now
Cade Metz | The New York Times
“Real scalpels, artificial intelligence—what could go wrong? …The [Berkeley] project is a part of a much wider effort to bring artificial intelligence into the operating room. Using many of the same technologies that underpin self-driving cars, autonomous drones and warehouse robots, researchers are working to automate surgical robots too. These methods are still a long way from everyday use, but progress is accelerating.”

FUTURE
This Tech Was Science Fiction 20 Years Ago. Now It’s Reality
Luke Dormehl | Digital Trends
“A couple of decades ago, kids were reading Harry Potter books, Pixar movies were all the rage, and Microsoft’s Xbox and Sony’s PlayStation were battling it out for video game supremacy. That doesn’t sound all that different from 2021. But technology has come a long way in that time. Not only is today’s tech far more powerful than it was 20 years ago, but a lot of the gadgets we thought of as science fiction have become part of our lives.”

LONGEVITY
How Long Can We Live?
Ferris Jabr | The New York Times Magazine
“As the global population approaches eight billion, and science discovers increasingly promising ways to slow or reverse aging in the lab, the question of human longevity’s potential limits is more urgent than ever. When their work is examined closely, it’s clear that longevity scientists hold a wide range of nuanced perspectives on the future of humanity.”

3D PRINTING
Forget Digging for Fossils. This Museum Printed a Full T-Rex Skeleton Instead
Luke Dormehl | Digital Trends
“For a team of researchers at the Naturalis Biodiversity Center in Leiden, the Netherlands, copying a T. rex took some state-of-the-art laser scanning technology, a giant 3D printer, a just-as-sizable postage bill, almost 45 million square millimeters of acrylic paint, and a group of experts wishing to push the boundaries of additive manufacturing.”

HEALTH
One Vaccine to Rule Them All
James Hamblin | The Atlantic
“i‘A universal SARS-CoV-2 vaccine is step one,’ [Anthony] Fauci said. Step two would be a universal coronavirus vaccine, capable of protecting us not only from SARS-CoV-2 in all its forms, but also from the inevitable emergence of new and different coronaviruses that might cause future pandemics. The race to create such a vaccine may prove one of the great feats of a generation.”

TECHNOLOGY
These Materials Could Make Science Fiction a Reality
John Markoff | The New York Times
“Imagine operating a computer by moving your hands in the air as Tony Stark does in Iron Man. Or using a smartphone to magnify an object as does the device that Harrison Ford’s character uses in Blade Runner. …These advances and a host of others on the horizon could happen because of metamaterials, making it possible to control beams of light with the same ease that computer chips control electricity.”

DRONES
Wingcopter Debuts a Triple-Drop Drone to Create ‘Logistical Highways in the Sky’
Aria Alamalhodaei | TechCrunch
“The Wingcopter 198, which was revealed Tuesday, is capable of making three separate deliveries per flight, the company said. Wingcopter has couched this multi-stop capability as a critical feature that will allow it to grow a cost-efficient—and hopefully profitable—drone-delivery-as-a-service business.”

SPACE
The Asteroid Impact Simulation Has Ended in Disaster
George Dvorsky | Gizmodo
“An international exercise to simulate an asteroid striking Earth has come to an end. With just six days to go before a fictitious impact, things don’t look good for a 185-mile-wide region between Prague and Munich. …This may sound like a grim role-playing game, but it’s very serious business. Led by NASA’s Jet Propulsion Laboratory’s Center for Near Earth Object Studies, the asteroid impact simulation is meant to prepare scientists, planners, and key decision makers for the real thing, should it ever occur.”
