Here’s how we could build a colony on an alien world
Posted by Julius Garcia in categories: alien life, habitats, solar power, space travel, sustainability
If the human race is to survive in the long-run, we will probably have to colonise other planets. Whether we make the Earth uninhabitable ourselves or it simply reaches the natural end of its ability to support life, one day we will have to look for a new home.
Hollywood films such as The Martian and Interstellar give us a glimpse of what may be in store for us. Mars is certainly the most habitable destination in our solar system, but there are thousands of exoplanets orbiting other stars that could be a replacement for our Earth. So what technology will we need to make this possible?

Microrobots learn from ciliates
Posted by Klaus Baldauf in categories: biotech/medical, chemistry, materials, robotics/AI
Ciliates can do amazing things: Being so tiny, the water in which they live is like thick honey to these microorganisms. In spite of this, however, they are able to self-propel through water by the synchronized movement of thousands of extremely thin filaments on their outer skin, called cilia. Researchers from the Max Planck Institute for Intelligent Systems in Stuttgart are now moving robots that are barely perceptible to the human eye in a similar manner through liquids. For these microswimmers, the scientists are neither employing complex driving elements nor external forces such as magnetic fields. The team of scientists headed by Peer Fischer have built a ciliate-inspired model using a material that combines the properties of liquid crystals and elastic rubbers, rendering the body capable of self-propelling upon exposure to green light. Mini submarines navigating the human body and detecting and curing diseases may still be the stuff of science fiction, but applications for the new development in Stuttgart could see the light-powered materials take the form of tiny medical assistants at the end of an endoscope.
Their tiny size makes life extremely difficult for swimming microorganisms. As their movement has virtually no momentum, the friction between the water and their outer skin slows them down considerably — much like trying to swim through thick honey. The viscosity of the medium also prevents the formation of turbulences, something that could transfer the force to the water and thereby drive the swimmer. For this reason, the filaments beat in a coordinated wave-like movement that runs along the entire body of the single-celled organism, similar to the legs of a centipede. These waves move the liquid along with them so that the ciliate — measuring roughly 100 micrometres, i.e. a tenth of a millimetre, as thick as a human hair — moves through the liquid.
“Our aim was to imitate this type of movement with a microrobot,” says Stefano Palagi, first author of the study at the Max Planck Institute for Intelligent Systems in Stuttgart, which also included collaborating scientists from the Universities of Cambridge, Stuttgart and Florence. Fischer, who is also a Professor for Physical Chemistry at the University of Stuttgart, states that it would be virtually impossible to build a mechanical machine at the length scale of the ciliate that also replicates its movement, as it would need to have hundreds of individual actuators, not to mention their control and energy supply.

Is this the future of work? Scientists predict which jobs will still be open to humans in 2035
Posted by Karen Hurst in categories: computing, employment, government, quantum physics, robotics/AI, security, space, virtual reality
1st; we all know in 30 years anything can change, wars can be fought & lost, natural disasters can occur, etc. However, posting for everyone’s amusement. 30 years ago which would be 1986; no one thought USSR would be broken up, 9/11 would happen creating the US Homeland Security, Lybia & Eygpt would overthrow their own leaders, that US Space missions would be outside the US Government, hacking at the levels we have today creating the CISO roles, of VR technology would exist, DNA and CRISPR would be discovered, etc.
So, who really knows what jobs will be fully automated v. not in 30 years or even created as a result of Quantum technology (Computing, Networking, Q-Dots for numerous thing that are not only technology, etc.). Just a fun article to share with everyone.
CSIRO says the Australian workplace of the future will be increasingly digitally-focused and automated, with titles such as online chaperone.
