DEET may be an effective mosquito repellent, but it can cause irritation, and has to be reapplied every few hours. Scientists are now working on a more innocuous, longer-laster alternative, that involves introducing genetically engineered bacteria to p… Continue reading Microbiome-altering mosquito repellent could last for two weeks
The U.S. government officials trying to test the country’s ability to respond to a major cyberattack thought they had pulled out all the stops. Engineers had planned to simulate the kind of security incident that would cause an electrical blackout, after all, and had even planned to hold the event on an isolated island off the coast of New York. Even with all that preparation, a once-in-a-century pandemic still wasn’t in the script. Until this year, National Guard personnel, Pentagon contractors and engineers at big U.S. utilities would typically gather in person to run through exercises involving dire scenarios, from a weeks-long power outage to a mock attack on utility computers that appeared to delete data. In October, though, COVID-19 forced planners from the departments of Defense and Energy to figure out how to run the event virtually, with participants plugged in from around the country. And they used the […]

DARPA has revealed that attempted air-recovery of three X-61A Gremlins missed success by just inches during recent tests over Dugway Proving Ground, Utah. Nine attempts to capture the drones as they flew behind a C-130 transport plane failed, and they … Continue reading DARPA’s X-61A Gremlin drone misses airborne retrieval by inches
Now that we drive around cars that are more like mobile data centers than simple transportation, there’s a wealth of data to be harvested when the inevitable crashes occur. After a recent Tesla crash on a California highway, a security researcher got a hold of the car’s “black box” and …read more
Out of the thousands of constraints and design decisions to consider when building a robot, the way it moves is perhaps one of the most fundamental. The method of movement constrains the design and use case for the robot perhaps more than any other parameter. A team of researchers at …read more
When it comes to methods of locomotion for robots, wheels are good for some things, while legs are better for others. Scientists are now working on a bot that combines the best of both worlds, with wheels that become legs.Continue ReadingCategory: Robo… Continue reading α-WaLTR robot will have wheels that double as legs
DARPA has awarded a US$14-million contract to the Gryphon Technologies engineering firm to develop and demonstrate a nuclear rocket engine for the agency’s Demonstration Rocket for Agile Cislunar Operations (DRACO) program. The High-Assay Low Enriched … Continue reading Gryphon Technologies to develop nuclear rocket engine for DARPA

Two variants of the Hypersonic Air-breathing Weapon Concept (HAWC) being developed for DARPA and the US Air Force have completed their final captive carry flight tests and are now cleared for their first free-flight tests within the next year.Continue … Continue reading DARPA/US Air Force hypersonic air-breathing weapon ready for free flight
DARPA has announced that its unmanned Gremlins X-61A air vehicle has completed a second round of aerial tests at the US Army’s Dugway Proving Ground in Utah. In late July 2020, the agency completed multiple air-vehicle ground and recovery tests as part… Continue reading DARPA’s Gremlins military drone completes key second test flight
