LLNL Reinventing Metal 3D Printing with Direct Metal Writing Process

Thu, 30 Mar 2017 06:05:06 EST

(image) Metal 3D printing has enormous potential to revolutionize modern manufacturing. However, the most popular metal printing processes, which use lasers to fuse together fine metal powder, have their limitations. Parts produced using Selective Laser Melting (SLM) and other powder-based metal techniques often end up with gaps or defects caused by a variety of factors. To overcome those drawbacks, Lawrence Livermore National Laboratory researchers, along with collaborators at Worchester Polytechnic Institute, are taking a wholly new approach to metal 3D printing with a process they're calling Direct Metal Writing, in which semisolid metal is directly extruded from a nozzle, like ketchup from a bottle.(image)



Blind Tadpoles Learn Visually After Researchers Graft Eyes Onto Tails and Treat Them with Neurotransmitter Drugs

Thu, 30 Mar 2017 06:00:00 EST

(image) Blind tadpoles were able to process visual information from eyes grafted onto their tails after being treated with a small molecule neurotransmitter drug that augmented innervation, integration, and function of the transplanted organs. The work, which used a pharmacological reagent already approved for use in humans, provides a potential road map for promoting innervation - the supply of nerves to a body part - in regenerative medicine.(image)

Unique Genome Architectures After Fertilisation in Single-Cell Embryos

Wed, 29 Mar 2017 13:00:00 EST

Using a newly developed method researchers at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) have been able to shed light on the complexity of genome reorganization occurring during the first hours after fertilization in the single-cell mammalian embryo. Their findings have recently been published in the journal Nature. The team of researchers (from three continents) have discovered that the egg and sperm genomes that co-exist in the single-cell embryo or zygote have a unique structure compared to other interphase cells. Understanding this specialized chromatin "ground state" has the potential to provide insights into the yet mysterious process of epigenetic reprogramming to totipotency, the ability to give rise to all cell types.(image)
