Are you ready to put mini robots in your mouth?
Do you get lazy about brushing your teeth? Well, soon microbots could do the whole thing for you. A multidisciplinary team at the University of Pennsylvania has created a novel automated way to perform brushing and flossing through robotics, according to a press release published by the institution last month.
The development could be particularly useful for those who lack the manual dexterity to clean their teeth effectively themselves.
A shapeshifting robotic microswarm may one day act as a toothbrush, rinse, and dental floss in one.
The technology, developed by a multidisciplinary team at the University of Pennsylvania, is poised to offer a new and automated way to perform the mundane but critical daily tasks of brushing and flossing. It’s a system that could be particularly valuable for those who lack the manual dexterity to clean their teeth effectively themselves.
The building blocks of these microrobots are iron oxide nanoparticles that have both catalytic and magnetic activity. Using a magnetic field, researchers could direct their motion and configuration to form either bristlelike structures that sweep away dental plaque from the broad surfaces of teeth, or elongated strings that can slip between teeth like a length of floss. In both instances, a catalytic reaction drives the nanoparticles to produce antimicrobials that kill harmful oral bacteria on site.
With all our global instability and still-nascent grasp on tech, adding in ASI would be lighting a match next to a fireworks factory.
Why do we think that reducing risks from AI is one of the most pressing issues of our time? There are technical safety issues that we believe could, in the worst case, lead to an existential threat to humanity.
Human languages are notoriously complex, and linguists have long thought it would be impossible to teach a machine how to analyze speech sounds and word structures in the way human investigators do.
But researchers at MIT, Cornell University, and McGill University have taken a step in this direction. They have demonstrated an artificial intelligence system that can learn the rules and patterns of human languages on its own.
When given words and examples of how those words change to express different grammatical functions (like tense, case, or gender) in one language, this machine-learning model comes up with rules that explain why the forms of those words change. For instance, it might learn that the letter “a” must be added to end of a word to make the masculine form feminine in Serbo-Croatian.

Researchers have developed a new chip-based beam steering technology that provides a promising route to small, cost-effective, and high-performance lidar systems. Lidar, or light detection and ranging, uses laser pulses to acquire 3D information about a scene or object. It is used in a wide range of applications such as autonomous driving, 3D holography, biomedical sensing, free-space optical communications, and virtual reality.
“Optical beam steering is a key technology for lidar systems, but conventional mechanical-based beam steering systems are bulky, expensive, sensitive to vibration, and limited in speed,” said research team leader Hao Hu from the Technical University of Denmark. “Although devices known as chip-based optical phased arrays (OPAs) can quickly and precisely steer light in a non-mechanical way, so far, these devices have had poor beam quality and a field of view typically below 100 degrees.”

No more dark side of the Moon?
An international research team headed by ETH Zurich has investigated the permanently shadowed regions of the Moon with the use of artificial intelligence. Future lunar missions will be able to find acceptable spots thanks to the knowledge they have gained about the region’s physical properties.
The research was published in Geophysical Research Letters on August 26.
We produce the first high-signal-to-noise ratio and-resolution orbital images over 44 shadowed regions within the Artemis exploration zone using an AI tool.
It will be reconfigured to meet testing needs.
The giant drone, RQ-4 RangeHawk, will soon be used to support the development of hypersonic missiles in the U.S., its manufacturer, Northrop Grumman, said in a press release.
Hypersonic missiles are the newest frontier in the weapons race, with countries like Russia and North Korea laying claims to have successfully demonstrated this technology. The U.S. hypersonic missile program has faced a few hiccups with repetitive test failures. Last month, the U.S. Air Force confirmed that its Air-launched Rapid Response Weapon (ARRW) had been successfully tested, almost after a year after similar claims from Russia.
GRAND FORKS, N.D. – Aug. 24, 2022 – Northrop Grumman Corporation’s (NYSE: NOC) RQ-4 RangeHawk is poised to support the SkyRange program’s U.S. hypersonic missile flight tests from its Grand Sky facility near Grand Forks, North Dakota. SkyRange is the Department of Defense Test Resource Management Center’s (TRMC) unmanned high-altitude, long-endurance, responsive mobile flight test system.
In support of the SkyRange initiative, Block 20 and 30 RQ-4B Global Hawk aircraft are being transferred to TRMC to be reconfigured into RangeHawks. The conversion will integrate advanced payloads to equip the aircraft with the capability to support the testing of hypersonic vehicles and other long-range weapons. RangeHawks provide over-the-horizon altitude, endurance and flexibility, which are critical for collecting telemetry and other data to monitor the vehicle during flight tests. Increasing the capacity of hypersonic vehicle testing furthers research and development necessary to remain competitive in the global landscape.
“Our RQ-4 RangeHawks will support the emerging class of hypersonic weapons and provide a combination of range, endurance and payload capacity,” said Jane Bishop, vice president and general manager, global surveillance, Northrop Grumman. “These aircraft will continue their role in vital national security missions while enabling us to bring premier aircraft design, modification, operations and sustainment work to the Grand Forks community.”
