A Longtime Educator Says K-12 Schools Need To Encourage Creativity And Curiosity

Posted by in categories: education, innovation

It is about time to revisit our assumptions about the public school system. What should be the goal of school education?


If we want to change a classroom to embrace innovation and questioning, we need the leaders and the school system as a whole to embrace innovation and questioning.

Incredible Sneak Peek of Mars Landing Sent Back

Posted by in categories: health, robotics/AI, space

The six-wheeled robot’s latest data since touching down yesterday include a series of images captured as the rover’s “jet pack” lowered it to the ground.

Less than a day after NASA ’s Mars 2020 Perseverance rover successfully landed on the surface of Mars, engineers and scientists at the agency’s Jet Propulsion Laboratory in Southern California were hard at work, awaiting the next transmissions from Perseverance. As data gradually came in, relayed by several spacecraft orbiting the Red Planet, the Perseverance team were relieved to see the rover’s health reports, which showed everything appeared to be working as expected.

Twisted trilayer graphene could help make high-temperature superconductors

Posted by in categories: materials, particle physics

Two’s company, but three’s a crowd – unless you’re trying to make graphene superconduct at higher temperatures. That is the finding of researchers at Harvard University in the US, who discovered that the superconducting state in three stacked and twisted layers of graphene is more robust to temperature increase than the equivalent state in two-layer graphene. The researchers also found evidence that superconductivity in the trilayer system comes from strong interactions between electrons, rather than weak ones as in most conventional superconductors – corroborating a result reported a few days earlier by a separate team at the Massachusetts Institute of Technology (MIT).

A sheet of graphene consists of a simple repetition of carbon atoms arranged in a two-dimensional hexagonal lattice. When two sheets of graphene are placed atop each other and slightly misaligned, they form a moiré pattern, or “stretched” superlattice that dramatically changes the electronic interactions in the material compared to its pristine counterpart. The misalignment angle is critical: in 2018, the MIT group, led by Pablo Jarillo-Herrero, discovered a so-called “magic” angle of 1.1° where the material switches from an insulator to a superconductor. This means the twisted graphene can carry electrical current with no resistance below a superconducting transition temperature, Tc, of 1.7 K.

Scientists 3D print new dragonfly-inspired ‘spiky-joints’ for treating wrist injuries

Posted by in categories: 3D printing, biotech/medical

Researchers from the German Kiel University have developed novel 3D printed ‘spiky-joints’ that provide wrist injury patients with a more flexible form of arm support.

Inspired by the natural wing micro-joints of the dragonfly, the spiky-joint features a novel interlocking mechanism that’s designed to cushion the wrist without impairing free movement. When set to its maximum rigidity, the scientists believe their device could be ideal for treating everyday strains and sprains, and preventing common hyperextension injuries in athletes.
