Scientists develop smart technology for synchronized 3D printing of concrete

Posted by in categories: 3D printing, robotics/AI, space

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a technology whereby two robots can work in unison to 3D-print a concrete structure. This method of concurrent 3D printing, known as swarm printing, paves the way for a team of mobile robots to print even bigger structures in the future. Developed by Assistant Professor Pham Quang Cuong and his team at NTU’s Singapore Centre for 3D Printing, this new multi-robot technology is reported in Automation in Construction. The NTU scientist was also behind the Ikea Bot project earlier this year, in which two robots assembled an Ikea chair in about nine minutes.

Using a specially formulated cement mix suitable for 3D , this new development will allow for unique concrete designs currently impossible with conventional casting. Structures can also be produced on demand and in a much shorter period.

Currently, 3D-printing of large concrete structures requires huge printers that are larger in size than the printed objects, which is unfeasible since most construction sites have space constraints. Using multiple that can 3D print in sync means large structures and specially designed facades can be printed anywhere, as long as there is enough space for the robots to move around the work site.

The Next Social Networks Could Be Brain-to-Brain

Posted by in categories: neuroscience, physics, space

It might already feel like social media is taking up too much of our mental space, but just wait until it’s literally inside of our brains.

Physicists and neuroscientists have developed the world’s first “brain-to-brain” network, using electroencephalograms (EEGs), which record electrical activity in the brain, and transcranial magnetic stimulation (TMS), which can transmit information into the brain, to allow people to communicate directly with each other’s brains — a new and thrilling (and a little terrifying?) example of science fiction brought to life.

Researchers at the University of Washington in Seattle announced last week that they successfully used their interface, which they call BrainNet, to have a small group of people play a collaborative “Tetris-like” game — with their minds.

Scientists Think They’ve Finally Found The Crushing Limits of Gravity Humans Could Survive

Posted by in categories: entertainment, space

They don’t call Hafþór Júlíus Björnsson ‘The Mountain’ for nothing.

In 2015, the strong man and Game of Thrones actor broke a millennium-old record by taking – or more accurately, staggering – five steps with a 650 kilogram (1,430 pound) log on his back.

To most of us, this was simply an extraordinary example of heroic strength. To scientists, this feat marked a crushing limit to the gravitational pull any mortal could ever hope to endure, setting a boundary on the mass of planets we might expect to colonise.

Settle down, guys. A skull-shaped asteroid is not headed for Earth this Halloween

Posted by in category: space

In 2015, the asteroid missed Earth by just 300,000 miles and was visible to those with good telescopes. This year, the closest it will come is 25 million miles — which is way too far to tell what it looks like.

There Is a Rogue Group of Stars Behaving Very Suspiciously in the Milky Way’s Disk

Posted by in categories: biotech/medical, space

The Milky Way has a violent past. When it isn’t swallowing renegade sausage galaxies, it seems to be waging endless games of interstellar tug-of-war with its nearest galactic neighbors — and not always winning. According to a new study published Sept. 19 in the journal Nature, one such encounter ended with a cosmic wound to the Milky Way’s disk that still hasn’t fully healed, 300 million years later.

That wound, researchers say, is visible in a cluster of several million stars that are not behaving as they should be. While still rotating around the Milky Way’s galactic center, these rogue stars also orbit around one another in a wobbly, spiral pattern that has only become more tangled over the past eon.

“We have observed shapes. [of star clusters] with different morphologies, such as a spiral similar to a snail’s shell,” lead study author Teresa Antoja, a researcher at the Institute of Cosmos Sciences (ICCUB) at the University of Barcelona, said in a statement. “These substructures allow us to conclude that the disk of our galaxy suffered an important gravitational disturbance.”

Iridium plans to launch CloudConnect satellite IoT system in partnership with Amazon Web Services

Posted by in categories: internet, space

Iridium, the satellite communications network, announced Thursday that it intends to work with Amazon Web Services to connect the leading cloud-provider’s internet-of-things services with Iridium’s satellite network in 2019.

This new service will be called CloudConnect. It builds on an existing IoT satellite network operated by Iridium to allow companies using AWS IoT services to reach places where the physical internet does not reach, which even in 2018 is a lot more places than you might imagine. Iridium is joining the AWS Partner Network along with this announcement, which will present Iridium’s satellite network as a deployment choice for AWS customers using its IoT services.
