Elon Musk talks to Chris Anderson, head and curator of the TED media organisation, about the challenges facing humanity in the coming decades – and why we should be more optimistic.

They discuss climate change, clean energy, electric vehicles, the rise of AI and robotics, brain-computer interfaces, self-driving cars, the revolutionary potential of reusable rockets and the forthcoming missions to Mars, as well as the other projects he is working on.

Imagine a future in which you could 3D-print an entire robot or stretchy, electronic medical device with the press of a button—no tedious hours spent assembling parts by hand.

That possibility may be closer than ever thanks to a recent advancement in 3D-printing technology led by engineers at CU Boulder. In a new study, the team lays out a strategy for using currently-available printers to create materials that meld solid and liquid components—a tricky feat if you don’t want your robot to collapse.

“I think there’s a future where we could, for example, fabricate a complete system like a robot using this process,” said Robert MacCurdy, senior author of the study and assistant professor in the Paul M. Rady Department of Mechanical Engineering.

Scientists from Beijing set a new quantum secure direct communication (QSDC) world record of 102.2 km (64 miles), a massive leap over the previous record of 18 km (11 miles), according to The Eurasian Times.

The research could eventually lead to a massive quantum communications network that would be virtually hacker-proof due to the nature of the technology.

The researchers, who published their findings in a paper in Nature, demonstrated transmission speeds of 0.54 bits per second, much slower than communications using classical computing devices. Still, this was fast enough for phone call and text message encryption over a distance of 30 km (19 miles).

Newly discovered Fermi arcs that can be controlled through magnetism could be the future of electronics based on electron spins.

These new Fermi arcs were discovered by a team of researchers from Ames Laboratory and Iowa State University, as well as collaborators from the United States, Germany, and the United Kingdom. During their investigation of the rare-earth monopnictide NdBi (neodymium-bismuth), the research team discovered a new type of Fermi arc that appeared at low temperatures when the material became antiferromagnetic, i.e., neighboring spins point in opposite directions.

Fermi surfaces in metals are a boundary between energy states that are occupied and unoccupied by electrons. Fermi surfaces are normally closed contours forming shapes such as spheres, ovoids, etc. Electrons at the Fermi surface control many properties of materials such as electrical and thermal conductivity, optical properties, etc. In extremely rare occasions, the Fermi surface contains disconnected segments that are known as Fermi arcs and often are associated with exotic states like superconductivity.

The brain is inarguably the single most important organ in the human body. It controls how we move, react, think and feel, and enables us to have complex emotions and memories. The brain is composed of approximately 86 billion neurons that form a complex network. These neurons receive, process, and transfer information using chemical and electrical signals.

You read that right, a hologram doctor.

It’s not science fiction: Hologram doctors beamed to space to visit astronauts.

In 2021, a team of hologram doctors was “holoported” to space to visit astronauts living aboard the International Space Station, NASA has revealed in a new post. The hologram teams, led by NASA flight surgeon Dr. Josef Schmid and Fernando De La Peña Llaca, CEO of software provider Aexa Aerospace, were the first humans to ever be “holoported” from Earth to space.
