The strongest magnetic field ever measured anywhere in the universe has failed to produce detectable magnetic monopoles. These hypothetical particles are predicted by many calculations of possible phenomena beyond the standard model of particle physics, but more than a century of searching still hasn’t turned up any signs of them.

All magnets that we know of have at least two poles – typically a north and south pole – with opposite magnetic charges. However, some models of the universe predict that there should be particles with only a north or a south pole called magnetic monopoles. For example, the existence of magnetic monopoles would explain why electric charge is quantised, meaning it comes in packets with a minimum size.

Over the past century or so, researchers have searched for magnetic monopoles both in space and in the smash-ups of particles at colliders, but they haven’t been found yet. Igor Ostrovskiy at the University of Alabama and his colleagues looked for monopoles being produced by a proposed phenomenon called the Schwinger effect, wherein extremely powerful magnetic fields could spontaneously produce magnetic particles and their antiparticles.

Koenigsegg has announced new high power, compact motors and powertrains for electric cars.

Christian von Koenigsegg is an inveterate tinkerer who has built a business on his ability to squeeze extraordinary amounts of power out of internal combustion engines. Lately, he has turned his talents to electric motors and drivetrains. On January 31, his company announced two breakthrough products that could transform the world of electric cars.

If scientists could measure the oscillations of just one energized cesium atom, they’d be able to keep perfect time, but they can’t due to a weird phenomenon called the standard quantum limit.

Instead, they have to measure thousands of atoms at once and then average out the results for atomic clocks, which leads to a just slightly imprecise second.

Now, MIT researchers have found a way to create a more precise atomic clock by exploiting another weird quantum phenomenon: entanglement.

For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes—pipes with walls that can be just one atom thick. The streams have confounded all theories of fluid dynamics; paradoxically, fluid passes more easily through narrower nanotubes, and in all nanotubes it moves with almost no friction. What friction there is has also defied explanation.

In an unprecedented mashup of fluid dynamics and quantum mechanics, researchers report in a new theoretical study published February 2 in Nature that they finally have an answer: ‘quantum friction.’

The proposed explanation is the first indication of quantum effects at the boundary of a solid and a liquid, says study lead author Nikita Kavokine, a research fellow at the Flatiron Institute’s Center for Computational Quantum Physics (CCQ) in New York City.

Dubbed the “Quark,” the motor weighs just 63 pounds.

Koenigsegg is also marketing an EV drive unit made up of two Quark motors, plus its small-but-powerful inverter, and small low-ratio planetary gearsets at each output shaft. The unit is called the “Terrier,” and serves up 670 hp and 811 lb-ft in a package that weighs just 187 pounds, and which offers torque vectoring across an axle. A Terrier can be bolted directly to a car’s monocoque as well.

More information on the Terrier unit is forthcoming, and presumably, it will be featured on future Koenigsegg products. As ever, the numbers are deeply impressive and entirely unsurprising from the innovative Swedish firm.

Cosmic physics mimicked on table-top as graphene enables Schwinger effect.

Researchers from the University of Illinois developed GPU-accelerated software to simulate a cell that metabolizes and grows like a living cell.

Every living cell contains its own bustling microcosm, with thousands of components responsible for energy production, protein building, gene transcription and more.

Scientists at the University of Illinois at Urbana-Champaign have built a 3D simulation that replicates these physical and chemical characteristics at a particle scale — creating a fully dynamic model that mimics the behavior of a living cell.

As soon as we understand how the human brain works, we should be able to make functional copies of our minds out of other materials. Given that everything is made of atoms, if you make a machine, in some sense it is made of the same kinds of materials as brains are made but organized either in very different ways or fundamentally the same ways.

That is not to say that the advantage has been proven yet. The quantum algorithm developed by IBM performed comparably to classical methods on the limited quantum processors that exist today – but those systems are still in their very early stages.

And with only a small number of qubits, today’s quantum computers are not capable of carrying out computations that are useful. They also remain crippled by the fragility of qubits, which are highly sensitive to environmental changes and are still prone to errors.

Rather, IBM and CERN are banking on future improvements in quantum hardware to demonstrate tangibly, and not only theoretically, that quantum algorithms have an advantage.
