Physics theory suggests that exotic excitations can exist in the form of bound states confined in the proximity of topological defects, for instance, in the case of Majorana zero modes that are trapped in vortices within topological superconducting materials. Better understanding these states could aid the development of new computational tools, including quantum technologies.

One phenomenon that has attracted attention over the past few years is “braiding,” which occurs when electrons in particular states (i.e., Majorana fermions) are braided with one another. Some physicists have theorized that this phenomenon could enable the development of a new type of quantum technology, namely topological quantum computers.

Researchers at Pennsylvania State University, University of California-Berkeley, Iowa State University, University of Pittsburgh, and Boston University have recently tested the hypothesis that braiding also occurs in particles other than electrons, such as photons (i.e., particles of light). In a paper published in Nature Physics, they present the first experimental demonstration of braiding using photonic topological zero modes.

Seismic waves, commonly associated with earthquakes, have been used by scientists to develop a universal scaling law for the sense of touch. A team, led by researchers at the University of Birmingham, used Rayleigh waves to create the first scaling law for touch sensitivity. The results are published in Science Advances.

The researchers are part of a European consortium (H-Reality) that are already using the theory to develop new Virtual Reality technologies that incorporate the sense of touch.

Rayleigh waves are created by impact between objects and are commonly thought to travel only along surfaces. The team discovered that, when it comes to touch, the waves also travel through layers of skin and bone and are picked up by the body’s touch receptor cells.

If the surge in digital finance is universal, the business models behind it are not. In Latin America look out for digital banks and e-commerce pioneers such as Nubank and MercadoLibre, owner of Mercado Pago. In South-East Asia Grab and Gojek, two ride-hailing services, are becoming “super-apps” with financial arms. Fintech firms now provide the majority of consumer loans in Sweden. In America credit-card firms such as Visa (the world’s most valuable financial firm), digital-finance giants such as PayPal (the sixth) and the big banks both co-operate and compete. Tech giants such as Apple and Alphabet are dipping their toes in, tempted by the financial industry’s $1.5trn global pool of profits.

Scientists long believed its function was simply to coordinate movements. Now they suspect it could do much more.

In the world of extreme auto, there are no machines that are more intimidating than monster trucks. With their massive engines and giant tires, monster trucks are associated with pure automotive mayhem and insanity. And if there is anything that’s still largely missing from the monster truck scene, it is the presence of all-electric vehicles. A Tesla Cybertruck could probably change this status quo.

Automotive 3D concept specialist shubbak.3D recently shared his take on what a “Monster Edition” of the Tesla Cybertruck could look like. The artist did pretty well in his concept, adding classic monster truck flourishes to the already domineering Cybertruck. The beast of the machine is pictured with numerous modifications such as a body kit, high suspension, and giant wheels.

China has deployed tens of thousands of soldiers on India’s Northern border, Secretary of State Michael Pompeo said, in further signs that a deadly military standoff between the world’s two most populous countries is far from cooling down.
