Perinatal hypoxia associated with long-term cerebellar learning deficits and Purkinje cell misfiring — ScienceDaily

Oxygen deprivation associated with preterm birth leaves telltale signs on the brains of newborns in the form of alterations to cerebellar white matter at the cellular and the physiological levels. Now, an experimental model of this chronic hypoxia reveals that those cellular alterations have behavioral consequences. Chronic sublethal hypoxia is associated with locomotor miscoordination and long-term cerebellar learning deficits in a clinically relevant model of neonatal brain injury, according to a study led by Children’s National Health System researchers published…

Notebook Innovation at Netflix – Netflix TechBlog – Medium

By Michelle Ufford, M Pacer, Matthew Seal, and Kyle Kelley Notebooks have rapidly grown in popularity among data scientists to become the de facto standard for quick prototyping and exploratory analysis. At Netflix, we’re pushing the boundaries even further, reimagining what a notebook can be, who can use it, and what they can do with it. And we’re making big investments to help make this vision a reality. In this post, we’ll share our motivations and why we find Jupyter…

A novel synthetic antibody enables conditional ‘protein knockdown’ in vertebrates — ScienceDaily

Research groups led by Dr. Jörg Mansfeld of the Biotechnology Center of the TU Dresden (BIOTEC) and Dr. Caren Norden of the Max Planck Institute for Molecular Cell Biology and Genetics (MPI-CBG) have developed a novel synthetic antibody that paves the way for an improved functional analysis of proteins. They combined auxin-inducible “protein knockdown” with a synthetic antibody to not only observe fluorescent proteins in living cells but also to rapidly remove them in a temporally controlled manner. Perhaps the…

First science with ALMA’s highest-frequency capabilities — ScienceDaily

The ALMA telescope in Chile has transformed how we see the universe, showing us otherwise invisible parts of the cosmos. This array of incredibly precise antennas studies a comparatively high-frequency sliver of radio light: waves that range from a few tenths of a millimeter to several millimeters in length. Recently, scientists pushed ALMA to its limits, harnessing the array’s highest-frequency (shortest wavelength) capabilities, which peer into a part of the electromagnetic spectrum that straddles the line between infrared light and…

Open Sourcing Facebook’s Solar-Powered Aircraft Design Tools – Facebook Code

Connectivity is at the heart of Facebook’s work to bring the world closer together. Together with our partners, we’re committed to working on a number of initiatives to build and leverage infrastructure, new technologies, tools, and programs to bring more people online. One of the ways we’re working to do this is through the development of next-generation connectivity technologies like Aquila, a high-altitude platform station (HAPS) connectivity system. Though we recently decided to shift our focus away from designing and…

Color effects from transparent 3-D printed nanostructures

Light hits the 3-D printed nanostructures from below. After it is transmitted through, the viewer sees only green light — the remaining colors are redirected. Credit: Thomas Auzinger Most of the objects we see are colored by pigments, but using pigments has disadvantages: such colors can fade, industrial pigments are often toxic, and certain color effects are impossible to achieve. The natural world, however, also exhibits structural coloration, where the microstructure of an object causes various colors to appear. Peacock…

Virtual reality providing real-world literacy and numeracy learning tool

PhD student Jonny Collins helps a user operate the system. Credit: University of Otago Virtual reality is moving beyond purely entertainment to become a potential tool in improving literacy, and the University of Otago is behind one ground-breaking approach. The University of Otago Information Science department has been working with Methodist Mission Southern to look at a totally new way of helping prisoners in the Otago Corrections Facility at Milburn to improve reading and writing skills. The resulting prototype…

From pine cones to an adaptive shading system

The movable sunshade made of bilayered wooden planks does not need to be controlled and runs without electricity, completely autonomously. Credit: Chiara Vailati/ETH Zurich An adjustable shading system that adapts itself independently over the course of the day, without sensors or motors and largely maintenance-free? It really is possible: an ETH doctoral student at the Institute for Building Materials has developed an alternative to motor-driven sunshades. It gets hot in the city in summer, and buildings in direct sunlight get…

Interactive software tool makes complex mold design simple

Objects created using the new design tool using resin casting or injection molding. Credit: Ran Zhang Most of the plastic objects we see are created using injection molding, but designing such molds is a difficult task, usually requiring experts. Now, computer scientists from the Institute of Science and Technology Austria (IST Austria), the University of Tokyo, and CONICET have created an interactive design tool that allows non-experts to create molds for an object of their choice. The software will be…

Fabric for Open Source Android – Kickstarter Engineering

So you’re thinking of working on an Android application that will be open source or you join a codebase that’s open source. There are many things to keep in mind when you’re working on an open source project. Here at Kickstarter we don’t have that many external dependencies in our Android application, but for the ones we have we need to keep our credentials secret from the public. We recently added Crashlytics, a kit available through Fabric, to our app…
