Good stuff

I love these examples of small, relatively simple medical device applications that can deliver such big value and comfort to patients. Chuck, you say that the device has already been used on upwards of 1,000 patients. Does that mean it's an available offering that's cleared the requisite FDA approval process?

Charles, I assumed that to be the case, which is why I don't really believe trying to switch to non-rare-earth materials is a valid option to deal with political problems.

TJ: I don't know if they could have used a different magnetic material, but I do know that they wanted a very powerful coupling force between the magnets because they are phyically separated by the plastic tube. It takes very strong hands to pull them apart. That's why they wanted neodymium.

Yesterday's articles included one about rare earth metal shortages caused by China cutbacks.  The product described in this article uses a neodymium magnet.  Is its component materials sourced from China?  Could this product have been made with a magnet that was not rare-earth, or something other than neodymium?

Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
If you see a hitchhiker along the road in Canada this summer, it may not be human. That’s because a robot is thumbing its way across our neighbor to the north as part of a collaborative research project by several Canadian universities.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
Stanford University researchers have found a way to realize what’s been called the “Holy Grail” of battery-design research -- designing a pure lithium anode for lithium-based batteries. The design has great potential to provide unprecedented efficiency and performance in lithium-based batteries that could substantially drive down the cost of electric vehicles and solve the charging problems associated with smartphones.
UK researchers have come up with a method for machining aerospace-grade, carbon fiber-reinforced composites, along with high-strength aerospace alloys, using an ultrasonically assisted machining device. It also works on high-strength aerospace alloys.
