MIT’s new thread-like robots could travel through blood vessels in the brain for more effective surgery – gpgmail


MIT has developed robotic thread that could make even the least invasive current brain surgery techniques even less so, and potentially make it easier and more accessible to treat brain blood vessel issues like blockages and lesions that can cause aneurysms and strokes.

The new development from MIT researchers combines robotics with current endovascular (i.e. within blood vessel) surgery techniques, reducing the risks associated with guiding incredibly thin wires through complicated brain blood vessel pathways. Today, this type of procedure, which is much less invasive than past methods of brain surgery, nonetheless requires an incredibly skilled surgeon to guide the wire manually. It’s a very difficult surgery for surgeons, and it also means that they’re exposed to radiation from the X-rays required to provide a view of the path they’re weaving through the patient’s brain.

These “robot-threads” developed by MIT expand on research done on so-called “hydrogels,” which are materials made mostly of water that work well within the human body. At the thread’s core is a material called “nitinol” that can bend, and is springy, meaning it has a natural tendency to spring back to its original shape when bent.

The material is coated in an ink-like substance, which is then bonded with a hydrogel, thus regulating it in a magnetically manipulable material that can still survive within the human body. Using a large magnet, the researchers could then steer the thread through a demonstration obstacle course they built to show off how it could work in a surgical situation.

MIT’s researchers also note that you can modify the core construction of the robot threads with other materials to serve different functions, and showed this by replacing the nitinol at its center with a fiber-optic filament, which in practice could be used to transmit laser light to blast away a blockage in a brain blood vessel.

The tech could be put to use to make it so surgeons can operate the threads from a safe distance — or even remotely. This would not only be safer for the doctors, but could also open up more access to this highly specialized kind of surgery for patients, too.

Northrup Grumman is among the companies tapped to make the US Army’s drone-killing lasers – gpgmail


Northrop Grumman is going to be working on the U.S. Army’s long-planned drone-killing lasers.

The Army wants to mount 50 kilowatt laser systems on top of its General Dynamics-designed Stryker vehicle as part of its U.S. Army Maneuver Short Range Air Defense (M-SHORAD) directed energy prototyping initiative.

Basically, the army wants to use these lasers to protect frontline combat troops against drone attacks.

The initiative includes integrating a directed energy weapon system on a Stryker vehicle as a pathfinding effort toward the U.S. Army M-SHORAD objective to provide more comprehensive protection of frontline combat units.

“Northrop Grumman is eager to leverage its portfolio of innovative, proven technologies and integration expertise to accelerate delivery of next-generation protection to our maneuver forces,” said Dan Verwiel, vice president and general manager, missile defense and protective systems, Northrop Grumman, in a statement.

The drone, helicopter, rocket, artillery and mortar defense system that the Army is looking to mount on a group of Stryker all-terrain vehicles could come from either Northrop Grumman or Raytheon, which was also tapped to develop tech for the project.

“The time is now to get directed energy weapons to the battlefield,” said Lt. Gen. L. Neil Thurgood, director of hypersonics, directed energy, space and rapid acquisition, in a statement. “The Army recognizes the need for directed energy lasers as part of the Army’s modernization plan. This is no longer a research effort or a demonstration effort. It is a strategic combat capability, and we are on the right path to get it in soldiers’ hands.”

For the Army, lasers extend the promise of reducing supply chain hurdles that are associated with conventional kinetic weapons. In May, the Army gave the green light to a strategy for accelerated prototyping and field use of a wide array of lasers for infantry, vehicles and air support.

While Raytheon and Northrop Grumman have both been tapped by the Army, the military will also entertain pitches from other vendors that want to carry out their own research, according to the Army.

It’s a potential $490 million contract for whoever wins the demonstration, and the Army expects to have the vehicles equipped in fiscal year 2022.

“Both the Army and commercial industry have made substantial improvements in the efficiency of high energy lasers — to the point where we can get militarily significant laser power onto a tactically relevant platform,” said Dr. Craig Robin, RCCTO Senior Research Scientist for Directed Energy Applications, in a statement. “Now, we are in position to quickly prototype, compete for the best solution, and deliver to a combat unit.”
