Stripping donor hearts and repopulating them with recipient-derived stem cells

Heart transplants have been around since 1967, but they're still anything but routine. In an effort to ensure a steady supply of compatible organs, a team of scientists from Massachusetts General Hospital (MGH) is working on ways to create bioengineered human hearts by first stripping donor hearts of cells that could provoke an immune response in a potential recipient, and then using the recipient's own induced pluripotent stem cells (iPSCs) to generate cardiac muscle cells that can be used to repopulate the heart in an automated bioreactor system.Read More

ExoMars 2016 is on its way to the Red Planet

The latest mission to Mars began its long journey today as the ExoMars 2016 lifted off at 09:31 GMT atop a Russian Proton-M/Breeze-M rocket at the Baikonur cosmodrome in Kazakhstan. A joint effort led by the European Space Agency (ESA) and Roscosmos, ExoMars 2016 is the first of a two-spacecraft mission to the Red Planet with the second unmanned probe scheduled to launch in 2018.Read More

Review: u-Jays on-ear headphones offer easy repair and upgrade

Shelling out a couple of hundred dollars for a pair of high-end headphones is something of an investment, so if they turn out to be fragile or aren't comfortable, it can be a waste of money. Swedish headphone developer Jays has swapped the bells-and-whistles approach for one of comfort and ruggedness for its latest u-Jays on-ear headphones.We plugged in a pair to see how they performed.Read More

DARPA looks to head off threats from off-the-shelf tech

In a world where 3D-printed guns are a reality, security threats are no longer the reserve of a hostile nation's military. With advanced technologies increasingly accessible to groups and individuals, DARPA is initiating a program called "Improv" that's intended to identify and anticipate potential threats from commercially-available off-the-shelf technology.Read More

Solid lubricant smooths the way for reduced weapon maintenance

One the most tedious yet vital tasks of the foot soldier is personal weapon cleaning and maintenance. Under field conditions, it has to be done daily and failure to do so can literally mean the difference between life and death. To reduce this task and make the weapon more durable and reliable, the US Army Research, Development, and Engineering Center (ARDEC) at Picatinny Arsenal, New Jersey is developing a Durable Solid Lubricant (DSL) that replaces the more conventional wet lubricants.Read More

Cool Runnings: Lockheed using microscopic drops of water to chill chips from the inside

Every year, electronic components shrink a bit more, allowing engineers to create more powerful and sophisticated chips. Unfortunately, these chips also generate a lot of heat, so novel cooling systems are needed to keep them running. As part of DARPA's ICECool-Applications research program, Lockheed Martin is developing a way of cooling high-powered microchips from the inside using microscopic drops of water.Read More

BMW looks to the future with shape-shifting Vision Next 100 concept

BMW's Vision Next 100 concept car might look like someone came to the tires and got a bit confused, but there is definite method to what seems like automotive madness. Developed as a celebration of the BMW Group's centenary, the Vision Next 100 is the company's attempt to take a long-term look at what the car of tomorrow might look like after autonomous drive technology has fundamentally changed automotive design.Read More

DARPA's unmanned X-Plane packs electric fans aplenty for vertical take-off and landing

If there was a competition for the oddest looking aircraft, then DARPA's VTOL Experimental Plane (VTOL X-Plane) would have to be in the running for the main prize. With a modularized, cellular wing design that looks like a flying set of cupboards, the unmanned aircraft is a hybrid of fixed-wing and rotary wing technologies designed to create a vertical take-off and landing (VTOL) aircraft that boasts greater range and speed capabilities.Read More
