3D printing with high-performance carbon fiber

Posted by in categories: 3D printing, materials

Lawrence Livermore National Laboratory (LLNL) researchers have become the first to 3D print aerospace-grade carbon fiber composites, opening the door to greater control and optimization of the lightweight, yet stronger than steel material.

The research, published by the journal Nature Scientific Reports online on Feb. 28, represents a “significant advance” in the development of micro-extrusion 3D printing techniques for carbon fiber, the authors reported.

Rapid changes point to origin of ultra-fast black hole ‘burps’

Posted by in category: cosmology

Gas outflows are common features of active supermassive black holes that reside in the center of large galaxies. Millions to billions of times the mass of the Sun, these black holes feed on the large disks of gas that swirl around them. Occasionally the black holes eat too much and burp out an ultra-fast wind, or outflow. These winds may have a strong influence on regulating the growth of the host galaxy by clearing the surrounding gas away and suppressing star formation.

Scientists have now made the most detailed observation yet of such an outflow, coming from an active galaxy named IRAS 13224–3809. The outflow’s temperature changed on time scales of less than an hour, which is hundreds of times faster than ever seen before. The rapid fluctuations in the outflow’s temperature indicated that the outflow was responding to X-ray emissions from the accretion disk, a dense zone of gas and other materials that surrounds the black hole.

The new observations are published in the journal Nature on March 2, 2017.

Team puts dark matter on the map

Posted by in categories: cosmology, particle physics

A Yale-led team has produced one of the highest-resolution maps of dark matter ever created, offering a detailed case for the existence of cold dark matter—sluggish particles that comprise the bulk of matter in the universe.

The dark matter map is derived from Hubble Space Telescope Frontier Fields data of a trio of galaxy clusters that act as cosmic magnifying glasses to peer into older, more distant parts of the , a phenomenon known as .

Yale astrophysicist Priyamvada Natarajan led an international team of researchers that analyzed the Hubble images. “With the data of these three lensing clusters we have successfully mapped the granularity of dark matter within the clusters in exquisite detail,” Natarajan said. “We have mapped all of the clumps of dark matter that the data permit us to detect, and have produced the most detailed topological map of the dark matter landscape to date.”

Forget SpaceX: 10 companies that will change space travel in 2017 & 2018

Posted by in categories: Elon Musk, space travel

SpaceX’s announcement that they will launch two tourists on a trip around the moon has captured imaginations with renewed speculation about the future of space travel and accessibility to the beyond.

“We are excited to announce that SpaceX has been approached to fly two private citizens on a trip around the moon late next year. They have already paid a significant deposit to do a moon mission,” Musk wrote in their announcement. “Like the Apollo astronauts before them, these individuals will travel into space carrying the hopes and dreams of all humankind, driven by the universal human spirit of exploration.”

Mark O’Connell’s book on the “transhumanist movement” came out yesterday

Posted by in categories: geopolitics, life extension, transhumanism

It’s really the first widely reviewed book by a prominent writer that specifically covers modern #transhumanism. While it’s done from a non-transhumanist perspective, it’s great reading and a BIG step forward for transhumanism and life extension (we need books about the movement that target laypeople). The last chapter is dedicated to the Immortality Bus and my presidential campaign. Additionally, many transhumanists and their work are covered in this comprehensive book. Grab a copy!…sr=8-1

Singapore to implement a digital identity programme inspired by Estonia

Posted by in categories: finance, government, transportation

The nation of Singapore is planning to implement a digital identity programme that is inspired by the one in Estonia.

The aim of the programme is to revamp its current national IDs, potentially allowing citizens simpler access to government services, financial transactions, and more.

According to the country’s prime minister Lee Hsien Loong, Singapore is not “going as fast as we ought to” in its drive to implement digital solutions and improving in areas such as electronic payment and transportation, news portal Today Online reported.

Forget Mammoths, We Could Bring Dinosaurs and Neanderthals Back to Life

Posted by in categories: biotech/medical, genetics

Dangerous thought.

The scientific world was set ablaze of late as discussions ramped up about the resurrection of the wholly mammoth. I know what you’re thinking: Jurassic Park. Well, not quite — but maybe not that far off, either. Dr. Michio Kaku, professor of theoretical physics at the City College of New York, wonders: what if we could clone the Neanderthal, or a dinosaur, based solely off their genomes?

‘Like a Bespoke Suit’: 3D-Printed Skin Breakthrough Gives Hope to Burn Victims

Posted by in categories: 3D printing, bioengineering, bioprinting, biotech/medical

A 3D bioprinter able to create human skin is already being used to help burns patients and carry out skin testing, Alfredo Brisac, CEO of Spanish bioengineering company BioDan, told Radio Sputnik.

Last month, scientists at Universidad Carlos III de Madrid and the BioDan Group presented a prototype 3D bioprinter that can create human skin suitable for transplantation to patients or for use in cosmetic, chemical or pharmaceutical testing.

One of the first living human organs to be created using bioprinting, the 3D-printed skin is created using bio-inks with living cells that are deposited onto a structure that replicates nature. The bio-ink contains the key elements of keratinocytes, fibroblasts and fibrin, which can recreate the structure of the skin.

This Smart AI Can Now Steal Code to Write Its Own Programs

Posted by in category: robotics/AI

Our artificial intelligence systems are continuing to get smarter, with scientists demonstrating that a system called DeepCoder is now clever enough to borrow bits of code from other programs to solve basic problems.

But the team behind the tool don’t want to put human programmers out of a job – they want to make it easier for people to build programs without any coding knowledge.

DeepCoder is a project run by Microsoft and the University of Cambridge, using deep learning techniques to mimic the neural network of a brain, where vast amounts of data are processed and evaluated to make decisions.
