Células artificiales

-

Parte de un concepto de bio-nanotecnología con incursiones en la nanomedicina según el cual se podrían hacer "células de diseño" con un "comportamiento muy eficiente" (más eficiente que las células ordinarias) por ejemplo en la entrega de oxígeno o haciendo y destruyendo virus.

En la actualidad forma parte de un Programa de investigación de la Nasa en que imitando a los glóbulos rojos (que solo saben transportar oxígeno) les permita llegar a una célula artificial eficiente.

Un grupo de investigadores universitarios está ayudando a la NASA a desarrollar esta célula artificial que pueda hacer de transportadora eficiente y otras potentes funciones dentro del cuerpo humano.



Este texto resume la intención de la NASA:

"Los Bioingenieros Dan Hammer y Dennis Discher de la Universidad de Pennsylvania, y Frank Bates de la Universidad de Minnesota, han creado un tipo de molécula especial -- un polímero -- que puede fabricar algo muy parecido a una membrana celular, y han podido convertir estas membranas en células artificiales, o Polimerosomas, que son más fuertes y más fácilmente manejables que las células reales.

Un polímero es simplemente una cadena de moléculas más pequeñas que se han entrelazado. La celulosa en las plantas y la lana en las ovejas, son polímeros naturales.

Podemos encontrar polímeros fabricados por el hombre en muchas formas, desde medias de nylon hasta repuestos para coches o relleno para muebles.." (ver Nasa).

At its one of the biggest ever hardware events, Google unveiled its Pixel smartphones. Coming in two variants, Pixel and Pixel XL, the new flagships pose a tough competition to Apple iPhones. These phones are powered by a quad-core Snapdragon 821 processor and 4GB RAM. Pixel also comes with the best-in-class camera and Google Assistant. After a series of leaks and speculations, Google took to the stage and revealed Pixel smartphone at its biggest hardware event in years. The phone looks just like the leaks suggested and resembles Apple’s iPhone–only without a physical button at the bottom. Google Pixel and Pixel XL specifications and features Google revealed two models of its new flagship smartphone — Pixel and Pixel XL. Pixel comes in the standard 5-inch size, while Pixel XL features a 5.5-inch XL screen. Both of these AMOLED screens are protected by Gorilla Glass 4. Pixel is powered by Snapdragon 821 processor clocked at 2.15 GHz, 4GB RAM, and comes with 32/128GB storage s

What Is Digital Twin Technology - And Why Is It So Important?

-

While the concept of a digital twin has been around since 2002, it’s only thanks to the Internet of Things (IoT) that it has become cost-effective to implement. And, it is so imperative to business today, it was named one of Gartner’s Top 10 Strategic Technology Trends for 2017. Quite simply, a digital twin is a virtual model of a process, product or service. This pairing of the virtual and physical worlds allows analysis of data and monitoring of systems to head off problems before they even occur, prevent downtime, develop new opportunities and even plan for the future by using simulations. Thomas Kaiser, SAP Senior Vice President of IoT, put it this way: “Digital twins are becoming a business imperative, covering the entire lifecycle of an asset or process and forming the foundation for connected products and services. Companies that fail to respond will be left behind.” How does a digital twin work? Think of a digital twin as a bridge between the physical and digital world. Firs
