Flat screen TVs that incorporate quantum dots are now commercially available, but it has been more difficult to create arrays of their elongated cousins, quantum rods, for commercial devices. Quantum rods can control both the polarization and color of light, to generate 3D images for virtual reality devices.
Using scaffolds made of folded DNA, MIT engineers have come up with a new way to precisely assemble arrays of quantum rods. By depositing quantum rods onto a DNA scaffold in a highly controlled way, the researchers can regulate their orientation, which is a key factor in determining the polarization of light emitted by the array. This makes it easier to add depth and dimensionality to a virtual scene.
"One of the challenges with quantum rods is: How do you align them all at the nanoscale so they're all pointing in the same direction?" says Mark Bathe, an MIT professor of biological engineering and the senior author of the new study. "When they're all pointing in the same direction on a 2D surface, then they all have the same properties of how they interact with light and control its polarization."
i’ve started babysitting for a VERY christian family which is great because they pay me a lot of money but as someone who was raised almost completely agnostic it’s kind of insane. the 2 year old keeps asking me to read her stories from the bible. (why are we reading david and goliath to a 2 year old????) the 5 year old told me today that he was going to bring his legos to heaven with him. he also has repeatedly told me that the lego spaceships he builds are stronger than jesus. (not sure what to say to that. do i deny it??? are things allowed to be stronger than jesus??) had to stop myself mid sentence today because i almost told them im not going to heaven which would DEFINITELY have caused several meltdowns. they’re also both completely fascinated by my nose ring

also I love that Grover gets separated from the kids and immediately starts playing mind games with a god. he's like finally I don't have to be a good role model for a second. let's talk brutality.
