Rutgers engineers have created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs.

Their most recent research results, published in the journal Nature Machine Intelligence, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.

Medical robots could reduce injuries and improve the efficiency and outcomes of procedures, as well as carry out tasks with minimal supervision when resources are limited. This would allow health care professionals to focus more on other critical aspects of medical care and enable emergency medical providers to bring advanced interventions and resuscitation efforts to remote and resource-limited areas.

The field of robotics took one step forward—followed by another, then several more—when a robot called Rainbow Dash recently taught itself to walk. The four-legged machine only required a few hours to learn to walk backward and forward, and turn right and left while doing so.

Researchers from Google, UC Berkeley and the Georgia Institute of Technology published a paper on the ArXiv preprint server describing a statistical AI technique known as deep reinforcement learning they used to produce this accomplishment, which is significant for several reasons.

DARPA has established a new partnership with U.S. industry to jointly develop and deploy advanced robotic capabilities in space. The agency has signed an Other Transactions for Prototypes agreement with Space Logistics, LLC, a wholly-owned subsidiary of Northrop Grumman Corporation, as its commercial partner for the Robotic Servicing of Geosynchronous Satellites (RSGS) program.

The RSGS program’s objective is to create a dexterous robotic operational capability in geosynchronous orbit that can extend satellite life spans, enhance resilience, and improve reliability for current U.S. space infrastructure. The first step is the RSGS program’s development of a dexterous robotic servicer, which a commercial enterprise will then operate.

“DARPA remains committed to a commercial partnership for the execution of the RSGS mission,” said Dr. Michael Leahy, director of DARPA’s Tactical Technology Office. “Building upon the successes of the DARPA Orbital Express mission and the recent successful docking of Space Logistics’ Mission Extension Vehicle-1, the agency seeks to bring dexterous on-orbit servicing to spacecraft in geosynchronous orbit (GEO), and to establish that inspection, repair, life extension, and improvement of our valuable GEO assets can be made possible and even routine.”

Phase 3 of DARPA’s Operational Fires (OpFires) program began in earnest this month with government and contractor staff finalizing the system architecture approach, including a plan to use existing components from ground-launched missile systems, along with new booster technologies designed to support future hypersonic weapons. Lockheed Martin Missiles and Fire Control is leading the integration effort for the third phase of the program, which will focus on first stage booster design and maturation, launcher development, and vehicle integration.

Broad participation from the Army’s Combat Capabilities Development Command, range safety offices, and performers from OpFires Phase 2 propulsion teams contributed to success in the early, critical stages of the program. Since 2018, OpFires has made impressive strides developing and demonstrating advanced booster technologies that had never been used in prior systems. Phase 1 and 2 performers Aerojet Rocketdyne, Exquadrum, and Sierra Nevada Corporation continue work towards throttle-able upper stage rocket motors suitable for tactical transport, storage, and engagement.

“The objective of DARPA’s OpFires program is to deliver an intermediate-range surface-to-surface missile in line with the Department of Defense’s push to field hypersonic platforms,” said MAJ Amber Walker (USA), the DARPA program manager for OpFires.

Autonomous and semi-autonomous systems need active illumination to navigate at night or underground. Switching on visible headlights or some other emitting system like lidar, however, has a significant drawback: It allows adversaries to detect a vehicle’s presence, in some cases from long distances away.

To eliminate this vulnerability, DARPA announced the Invisible Headlights program. The fundamental research effort seeks to discover and quantify information contained in ambient thermal emissions in a wide variety of environments and to create new passive 3D sensors and algorithms to exploit that information.

“We’re aiming to make completely passive navigation in pitch dark conditions possible,” said Joe Altepeter, program manager in DARPA’s Defense Sciences Office. “In the depths of a cave or in the dark of a moonless, starless night with dense fog, current autonomous systems can’t make sense of the environment without radiating some signal—whether it’s a laser pulse, radar or visible light beam—all of which we want to avoid. If it involves emitting a signal, it’s not invisible for the sake of this program.”

EXCLUSIVE: In a plot which seems straight out of the Netflix original series Altered Carbon, experts have told Daily Star Online the wealthy could soon achieve immortality.

Good dog :3.

Hank and Storm show Gray Hall how they do their jobs with the Philadelphia Police.

The dogs’ handlers, Officer Alvin Outlaw, who works with Storm, and Officer Richard Treston, who is paired with Hank, say it was the weeks of training and guidance that prepared them for the heavily wooded conditions that they encountered in Bucks County. Hank sniffed out the grave first and Storm followed up with the same results.

Elon Musk and the late Stephen Hawking are not alone in their calls for humanity to become a multi-planetary species. But they certainly are the most visible advocates for space colonization. And while the moon might be the most obvious jumping off point to the solar system and beyond, nothing stands out as a potential site for long term settlement more than Mars.

But just how realistic is sending astronauts to the Red Planet anytime soon–let alone colonizing it permanently? The obstacles are many, and aerospace engineering may well be the least of them. The human biological, psychological tolss and survival strategies–radiation, low gravity, isolation and the marshalling air, water, and food resources–all stand in the way. And then there is the economic cost and the political and public will. In this edition of Seeking Delphi,™ I talk to former NASA Mars mission navigator, Moriba Jah, about the many challenges of leaving of our home planet.
