Scientists might have reached the theoretical limit of how strong this particular material can get, designing the first-ever super-light carbon nanostructure that’s stronger than diamond.

The latest development in the nanoworld of carbon comes from a team that has designed something called carbon plate-nanolattices. Under a scanning electron microscope, they look like little cubes, and the math indicated that this structure would be incredibly strong, but it’s been too difficult to actually make, until now.

The team’s success was made possible by a 3D printing process called two-photon polymerization direct laser writing, which is essentially 3D printing on the level of atoms and photons.

Artificial sentience straddles the fields of philosophy and engineering.

Throw robots into the mix and it gets really interesting.

Seeker examines what it mean for a robot to be self-aware.

The Creative Machines Lab at Columbia University https://www.creativemachineslab.com/“At the Creative Machines Lab we build robots that do what you’d least expect robots to do: Self replicate, self-reflect, ask questions, and even be creative. We develop machines that can design and make other machines – automatically.”

Commercially viable quantum computing could be here sooner than you think, thanks to a new innovation that shrinks quantum tech down onto a chip: a cryochip.

Seeker explains:

It seems like quantum computers will likely be a big part of our computing future—but getting them to do anything super useful has been famously difficult. Lots of new technologies are aiming to get commercially viable quantum computing here just a little bit faster, including one innovation that shrinks quantum technology down onto a chip.

Seeker examines how research into quantum computing may uncover more about the universe.

Scientists have built an advanced instrument with parts from a quantum computer that’s sensitive enough to listen for the signal of a dark matter particle. The Axion Dark Matter Experiment (ADMX) at the University of Washington is the world’s first dark matter experiment that’s hunting specifically for axions.

Seeker examines a leaked paper from Google claimed that a quantum computer demonstrated “quantum supremacy.”

But what does that mean exactly?

Quantum computers’ potential and the advantages they promise over classical computers all remain largely theoretical, and hypothetically speaking, it is predicted that quantum computers will be able to solve problems that are beyond the reach of the classical computers we use today. Passing such a threshold will be considered proof of what we call “quantum supremacy.”
