ELON MUSK wants to plump humans on Mars by 2024 and the first batch of settlers could live in 3D-printed home pods that pack hologram computers.
You’ll be able to tour the Red Planet habitat in virtual reality and view a scale model of the sci-fi living space at the Goodwood Festival of Speed next month.
In a profound talk about technology and power, author and historian Yuval Noah Harari explains the important difference between fascism and nationalism — and what the consolidation of our data means for the future of democracy. Appearing as a hologram live from Tel Aviv, Harari warns that the greatest danger that now faces liberal democracy is that the revolution in information technology will make dictatorships more efficient and capable of control. “The enemies of liberal democracy hack our feelings of fear and hate and vanity, and then use these feelings to polarize and destroy,” Harari says. “It is the responsibility of all of us to get to know our weaknesses and make sure they don’t become weapons.” (Followed by a brief conversation with TED curator Chris Anderson)

One of the enduring sci-fi moments of the big screen—R2-D2 beaming a 3D image of Princess Leia into thin air in “Star Wars”—is closer to reality thanks to the smallest of screens: dust-like particles.
Scientists have figured out how to manipulate nearly unseen specks in the air and use them to create 3D images that are more realistic and clearer than holograms, according to a study in Wednesday’s journal Nature. The study’s lead author, Daniel Smalley, said the new technology is “printing something in space, just erasing it very quickly.”
In this case, scientists created a small butterfly appearing to dance above a finger and an image of a graduate student imitating Leia in the Star Wars scene.
Why aren’t holograms or related optical devices part of our everyday lives yet? The technologies can be created by using magnetic fields to alter the path of light, but the materials that can do that are expensive, brittle and opaque. Some only work in temperatures as cold as the vacuum of space.

Now, researchers from the University of Michigan and the Federal University of Sao Carlos in Brazil have demonstrated that inexpensive nanoparticles in a gel can replace traditional materials at a drastically reduced cost. And their approach works at room temperature.
A new technique for recording image information onto a surface creates the ability for one space to contain multiple holographic snapshots, depending on how you look at it.
With this new research, cramming numerous holograms without loss of resolution on the same material could open the way to some fascinating new applications.
Holograms have been around for over half a century, serving as art, entertainment, and foils to counterfeiting. It’s been a hard and fast rule that no matter which way you view a hologram, the same object would appear in three dimensions. Until now.
As fast as fiber optic lines have become, they’re still hamstrung by one key limitation: you still need to transmit that data over wires, which limits where you can transmit and the affordability of the fastest connections. Scientists may have a way to eliminate those cables while offering even faster speeds, though. They’ve discovered a way to ‘twist’ photons in a way that not only crams more data into each transmission, but survives interference from turbulent air. If you pass light through a special hologram, you can give photons an optical angular momentum that lets them carry more than just 1s and 0s — and so long as the light’s phase and intensity are right, you can reliably beam that data over long distances.
The research team successfully tested just such a link over a 1-mile stretch in Germany, making sure that it took place in an urban environment where the turbulence from taller buildings could theoretically cause chaos.
There’s still a lot of work to be done before this kind of wireless networking is practical. How do you serve a large number of people, and how is data affected by rain or snow? Still, it’s promising. The technology is clearly limited by the challenges of transmitting light (you couldn’t use this to transmit indoors, for obvious reasons), but it could be instrumental to the next generation of last-mile wireless networks. Instead of having to painstakingly wire homes and offices to achieve multi-gigabit speeds, internet providers could use light-based wireless links for large parts of their network and install cabling only when it’s absolutely necessary.
VNTANA and Satisfi Labs are collaborating on a hologram concierge platform. The finished product will allow businesses to combine a virtual assistant powered by artificial intelligence with augmented reality visuals.
VNTANA and Satisfi Labs have announced a new platform that will allow businesses to develop a hologram concierge to be used in business. The project fuses artificial intelligence (AI) with augmented reality (AR) technology to produce a 3D persona that can interact with customers.
For millennials and the generations to follow, the future will differ radically from their parents’ world. Massively powerful digital technologies will bring seismic changes in the lifestyles, opportunities, privileges and choices experienced by young people compared to their parents.
