"Mark Rober's DNA Nerf Gun: Revolutionizing Medical Breakthroughs"

Mark Rober breaks the record for the world's smallest Nerf gun five times, culminating in ones made out of DNA using a technique called DNA origami. These nano Nerf guns, at 100 nanometers in length, could not be seen with the naked eye and required an atomic force microscope to view. Rober suggests that the technology behind these miniaturized Nerf guns could have potential applications in medical breakthroughs, such as targeting and eliminating cancer cells or enhancing healthy cells.

"Nanopore-Electronic Hybrid Device Revolutionizes Disease Detection"

Researchers at UC Santa Cruz and MIT have developed a bioprotonic system that combines electronic components with biological components to detect biomolecules indicating the presence of human disease. The system utilizes a DNA nanopore, created through DNA origami, which acts as a channel for protons. The device translates the proton signal into an electronic signal, allowing researchers to detect the presence of biomolecules. The researchers demonstrated the system's potential for detecting B-type natriuretic peptide, an indicator of cardiac disease, and envision the device being able to detect multiple types of biomolecules in the future.

"Quantum Rods Pave the Way for Ultra High-Def Virtual Reality"

Researchers at MIT, funded by the Department of Energy, have made a breakthrough in utilizing DNA to align quantum rods, which could lead to advancements in televisions and virtual reality (VR) devices. Quantum rods offer superior optical properties, including the ability to control polarization and color of light, making them ideal for VR and holographic technology. The researchers developed a technique that effectively aligns quantum rods, is cost-effective, and can be performed in minutes. By using DNA origami scaffolds, the team was able to create precise arrays of aligned quantum rods, paving the way for improved electronics applications and ultra-realistic VR displays.

LEGO Robot Accelerates DNA Purification for Nanostructures

Bioengineers at Arizona State University have developed a LEGO robot as a gradient mixer to purify DNA origami nanostructures. The mixer, made using off-the-shelf LEGO kits, spins material inside cylindrical tubes to create a gradient. The robot performed as well as commercial versions but at a lower cost. The researchers suggest that this approach could be used to create other expensive lab machines.
