Global thermonuclear war. The slight possibility that a massive asteroid could boop Earth. Jenga. These are a few of the things that give humans debilitating anxiety.

Robots can’t solve any of these problems for us, but one machine can now brave the angst that is the crumbling tower of wooden blocks: Researchers at MIT report today in Science Robotics that they’ve engineered a robot to teach itself the complex physics of Jenga. This, though, is no game—it’s a big step in the daunting quest to get robots to manipulate objects in the real world.

Arthur Ashkin is the oldest person ever awarded a Nobel Prize. But he says he’s not done discovering yet. He still works every day.

The physics of ferromagnetism has long befuddled scientists, but a familiar puzzle is getting them closer to an answer.

The Big Bang didn’t just result in our familiar universe, according to a mind-bending new theory — it also generated a second “anti-universe” that extended backwards in time, like a mirror image of our own.

A new story in Physics World explores the new theory, which was proposed by a trio of Canadian physicists who say that it could explain the existence of dark matter.

The new theory, which is laid out in a recent paper in the journal Physical Review of Letters, aims to preserve a rule of physics called CPT symmetry. In the anti-universe before the Big Bang, it suggests, time ran backwards and the cosmos were made of antimatter instead of matter.

From Reese Witherspoon to Jeff Bezos, those who are super successful in their chosen domain accept this truth.

The energy use of data centers is a major drag on resources, but they also use a lot of water. Any technology that increases their efficiency while reducing resource waste is a good thing.

“Now, Forced Physics, a company based in Scottsdale, Ariz., has developed a low-power system that it says could slash a data center’s energy requirements for cooling by 90 percent. The company’s JouleForce conductor is a passive system that uses ambient, filtered, nonrefrigerated air to whisk heat away from computer chips.”

The company that created it, Forced Physics, plans to install the technology in a pilot plant in February.

For the first time ever, an international team of researchers imaged the microscopic state of negative capacitance. This novel result provides researchers with fundamental, atomistic insight into the physics of negative capacitance, which could have far-reaching consequences for energy-efficient electronics.

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?

CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.

Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”

“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”
