1. Alzheimer's May Not Originate in the Brain
The long assumption that Alzheimer's disease originates in the brain may not be true after all--as new findings indicate the disease could be triggered by breakdowns elsewhere in the body.
2. Scientists Discover How to Control Electrons in Graphene
The problem of electrons moving freely through graphene with no control has finally been solved. Researchers from Rutgers University-New Brunswick have tamed the unruly electrons in graphene by sending voltage through a high-tech microscope with an extremely sharp tip about the size of an atom.
3. Nanopartides Used to Help Treat Spinal Cord Injuries
A new nanopartide treatment could help those suffering from spinal cord injuries walk better after their injury, while also reducing secondary nerve damage caused by inflammation and internal scarring. A research team from Northwestern University has created a biodegradable nanopartide that can be injected after spinal cord trauma to prevent inflammation and internal scarring that inhibits the repair process.
4. Next-Generation Drones Inspired by Nature
The key to designing the next generation of drones could reside in the animal kingdom.Engineers are exploring an area of research called biomimetics, which is an interdisciplinary field combining principles of engineering, chemistry, and biology. R&D Magazine highlighted some of the nature-based innovations being worked on at laboratories around the world.
5. What's Next For CAR T: The Potential of Engineering Immune Cells to Treat Cancer
It is not often that an entirely new, effective, class of therapy is discovered, especially in a disease as difficult to treat as cancer. It is even less common that a completely new therapeutic is effective in a large majority of patients right from the start. But chimeric antigen receptorT cell therapy--CART-cell therapy--is anything but typical. In an interview with R&D Magazine Stephan Grupp, MD, PhD shared his insights on CAR T-cell therapy's impact.
6. Understanding Defects Found in 3D Printed Products
An effect called "splatter" can emerge during Powder Bed Fusion production process where particles of liquid metal fly out of the laser's path and land back on certain parts contaminating the powder bed therefore affecting the build quality of a layer.This can lead to a variety of defects like roughness, porosity, and lack of fusion in these finished metal parts. Previous experiments believed that this issue occurred as a result of laser-induced recoil pressure, but an investigation done by researchers at the Lawrence Livermore National Laboratory dispelled this notion.
