In our Universe, a black hole is bounded by a spherical surface called an event horizon. Whereas in ordinary three-dimensional space it takes a two-dimensional object (a surface) to create a boundary inside a black hole, in the bulk universe the event horizon of a 4D black hole would be a 3D object - a shape called a hypersphere. When Afshordi's team modelled the death of a 4D star, they found that the ejected material would form a 3D brane surrounding that 3D event horizon, and slowly expand. The authors postulate that the 3D Universe we live in might be just such a brane - and that we detect the brane's growth as cosmic expansion. "Astronomers measured that expansion and extrapolated back that the Universe must have begun with a Big Bang - but that is just a mirage," says Afshordi.

"Der Mediziner Glenn Green und der Maschinenbauer Scott Hollister erwirkten eine Notfallfreigabe ihrer noch unerprobten Technik bei der US-Aufsichtbehörde und entwickelten ein Implantat, das aus dem Polymer Polycaprolacton gefertigt wurde. Dieser Kunststoff wird vom Körper langsam abgebaut. Die Stützkonstruktion, die den Hauptbronchus auseinanderhält und sich dennoch bewegen und leicht dehnen lässt, soll sich innerhalb von ungefähr drei Jahren auflösen, damit das Wachstum des Kindes nicht behindert wird. Green und Hollister haben den Splint auf Basis einer Computertomographie des Kindes am Rechner konstruiert und dann mit Hilfe eines 3D-Druckers hergestellt. Der Splint, der wie eine längs aufgeschnittene Röhre aussieht, wurde Anfang Februar 2012 am C.S. Mott Children's Hospital mit Einwilligung der Eltern eingesetzt. Das Implantat bietet dem Bronchus eine Skelett-artige Stütze. Drei Wochen nach dem Eingriff konnte die Gerätebeatmung beendet werden. Auch ein Jahr nach dem Eingriff wurde eine normale Entwicklung der Luftröhre diagnostiziert."

"A team of scientists at Oxford University have printed - yes, printed - what could be the predecessors to usable synthetic human tissue. The researchers released a paper called A Tissue-Like Material, announcing that they created their own version of a 3D printer, saying the current ones on the market couldn't print what they were after, according to PhsyOrg. And what were they after? A protein sack of water that can mold itself into different shapes and perform similar functions to human cells. After developing the printer, the team was able to print out a series of droplets that formed a network of human-like cells that could act like nerves and send electrical signals across the network."

BrainBrowser is web-based, 3D visualization tool for neuroimaging. Using web-standard technologies, such as WebGL and HTML5, it allows for real time manipulation and analysis of 3D neuroimaging data whether it be precalculated maps, such as the MACACC data set (Mapping Anatomical Correlations Across Cerebral Cortex), or models provided by the user in MNI object format and data in one of the many currently supported formats (Minc, Nifti, object files, plain text).

"Researchers are using these Philly-made 'bioprinters' to make hearts, stomachs, BioBots makes a device that 3D-prints living cells instead of plastic."

"Gedrucktes Essen: Algen, Gras und Insekten als Nährstofflieferanten Bis jetzt ist es nicht viel mehr als ein interessantes Konzept, aber der Nasa ist es immerhin 125.000 Dollar wert. So viel investiert die amerikanische Raumfahrtbehörde in die Entwicklung eines 3-D-Druckers für Lebensmittel. Dabei geht es weniger um die Realisierung von Science-Fiction-Visionen wie dem Replikator aus "Star Trek". Vielmehr stellt sich mit Blick auf künftig geplante Langzeitmissionen zum Mars die Frage nach der Lebensmittelversorgung der Astronauten. Der Entwurf des Nasa-Partners Systems & Materials Research Corporation (SMRC) sieht dabei vor, dass ein 3-D-Drucker die verschiedenen Bestandteile menschlicher Ernährung in pulverisierter, lagerfähiger Form verarbeitet. Zucker, Proteine und Kohlenhydrate würden dann je nach zuvor vom Computer geladenen "Rezept" zusammengestellt und tellerfertig produziert. Die ersten Entwürfe für das Astronautenessen der Zukunft sehen allerdings noch etwas fremdartig aus und erinnern ein wenig an Hundekuchen. Hinter SMRC steht Anjan Contractor, ein Ingenieur mit einiger Erfahrung im Bereich des dreidimensionalen Druckens. In den kommenden Wochen will er sich zunächst an die Umsetzung eines vergleichsweise einfachen Rezepts machen und mit einem 3-D-Drucker eine Pizza herstelle"

"Tissue engineering is often thought of as a "Frankenstein-type" science where scientists build living tissues from otherwise "dead" tissues and organs. However, current advances in technology mean bringing life to cadaveric tissues is becoming more and more sophisticated: less of the lightning strikes and more stem cells and 3D printing!"

The Singularity is massively awesome utopia, perfect happiness.

Droplet network printer ""We aren't trying to make materials that faithfully resemble tissues, but rather structures that can carry out the functions of tissues," said Professor Hagan Bayley of Oxford University's Department of Chemistry, who led the research. "We've shown that it is possible to create networks of tens of thousands of connected droplets. The droplets can be printed with protein pores to form pathways through the network that mimic nerves and are able to transmit electrical signals from one side of a network to the other.""

" Dieses intelligente Rückstoßprinzip stand Forschern des Fraunhofer-Instituts für Produktionstechnik und Automatisierung IPA beim Entwickeln eines Unterwasserantriebs Pate. »Kraken nutzen diese Art der Fortbewegung hauptsächlich für eine plötzliche schnelle Flucht. Das System ist zwar einfach, aber effektiv. Die Oktopoden können damit über kurze Strecken enorm beschleunigen«, sagt Andreas Fischer, Ingenieur am IPA in Stuttgart. »Wir haben das Antriebsprinzip in unsere Unterwasseraktoren integriert: Vier elastische Kunststoffbälle mit einem mechanischen Innenleben pumpen Wasser und sorgen so für Vortrieb.«"

James Newhard is Director of Archaeology at the College of Charleston, where he works to bring 3D imaging, mobile technology and geographic information systems to a field more popularly associated with shovels and dusty brushes. Gizmodo got in touch with Dr. Newhard to learn how he uses emerging tech to dig deep into ancient societies.

"I am a Neuroscientist working at the Centre for Integrative Neuroscience (CIN), University of Tübingen, Germany. In My Research I use a combination of 2-photon imaging, electrophysiology and computational modelling to unravel principles of synaptic and network computations in the vertebrate early visual system. Outside my regular work I am also co-founder of a not-for-profit organisation TReND in Africa, dedicated to foster Neuroscience Education and Research on the African continent. Moreover I am contributor to Open Labware, the design and building of open source laboratory equipment based on off-the-shelf electronics and simple mechanics as made possible by 3D printing"

"100,000 skin samples every year (that's 5 square meters of skin or a full cow's-worth annually) at its lab in Lyon. Currently, the company receives bits of donor skin from plastic surgery procedures. Then L'Oreal breaks the samples down into individual cells, re-cultures and grows them into .5 cm testing squares. The whole process takes about a week to complete but could soon be done much faster thanks to Organovo's NovoGen Bioprinting Platform. ... The bioprinter has already partnered with Merk to create liver and kidney tissues"

Bacteria are often social creatures. Suspended in colonies of varying shapes and sizes, these microbes communicate with their brethren and even other bacterial species - interactions that can sometimes make them more deadly or more resistant to antibiotics. Now, bacterial colonies sculpted into custom shapes by a 3-D printer could be a key to understanding how some antibiotic-resistant infections develop. The new technique uses methods similar to those employed by commercial 3-D printers, which extrude plastic, to create gelatin-based bacterial breeding grounds. These microbial condos can be carved into almost any three-dimensional shape, including pyramids and nested spheres.

A new project to create a 3D map of space so large that scientists can find a 500 million-light-year-size remnant from the early universe inside it began operation last month. The Baryon Oscillation Spectroscopic Survey opened its eyes to the universe, taking in data from hundreds of galaxies and quasars in the constellation Aquarius, from its perch on the Apache Point Observatory in New Mexico. Eventually, it will image two million galaxies and quasars.
