An international team led by physicists from the Ludwig-Maximilians Universitaet (LMU) in Munich realized a novel genuine time-dependent topological system with ultracold atoms in periodically-driven optical honeycomb lattices.

Topological phases of matter have attracted a lot of interest due to their unique electronic properties that often result in exotic surface or boundary modes, whose existence is rooted in the non-trivial topological properties of the underlying system. In particular, the robustness of these properties makes them interesting for applications.

Periodic driving has emerged as an important technique to emulate the physics of undriven topological solid-state systems. The properties of driven topological systems, however, transcend those of their static counterparts. Using a BEC of 39K loaded into a periodically-modulated optical honeycomb lattice, we could generate such a time-dependent topological system.

When we think of Earth and its neighboring planets orbiting around our common host star, we picture the center of the Solar System as smack in the middle of the Sun. However, that’s not entirely true, according to new research.

The planets and the Sun actually orbit around a common center of mass. And for the first time, a team of astronomers has pinpointed the center of the entire Solar System down to within 100 meters, the most precise calculation yet.

Clint Brauer’s farm outside of Cheney, Kansas, could be described as Old MacDonald’s Farm plus robots. Along with 5,500 square feet of vegetable-growing greenhouses, classes teaching local families to grow their food, a herd of 105 sheep, and Warren G—a banana-eating llama named after the rapper—is a fleet of ten, 140-pound, battery-operated robots.

Brauer, the co-founder of Greenfield Robotics, grew up a farm kid. He left for the big city tech and digital world, but eventually made his way back to the family farm. Now, it’s the R&D headquarters for the Greenfield Robotics team, plus a working farm.

When Brauer returned to his agricultural roots, he did so with a purpose: to prove that food could be grown without harmful chemicals and by embracing soil- and planet-friendly practices. He did just that, becoming one of the premier farmers growing vegetables in Kansas without pesticides, selling to local markets, grocery store chains, and chefs.

The papers appear to feature the same pictures as others, raising doubts about the checks on scientific research, The Wall Street Journal reported.

And America’s can’t compete.

The best way to prevent this is by focusing on the basics. America needs a major all-of-society push to increase the number of U.S. students being trained in both the fundamentals of math and in the more advanced, rigorous, and creative mathematics. Leadership in implementing this effort will have to come from the U.S. government and leading technology companies, and through the funding of ambitious programs. A few ideas come to mind: talent-spotting schemes, the establishment of math centers, and a modern successor to the post-Sputnik National Defense Education Act, which would provide math scholarships to promising students along with guaranteed employment in either public or private enterprises.

Forget about “AI” itself: it’s all about the math, and America is failing to train enough citizens in the right kinds of mathematics to remain dominant.

Authorities in the northern Chinese region of Inner Mongolia have issued an early epidemic warning after a resident contracted bubonic plague.

Bubonic plague, known as the ‘Black Death’ in the Middle Ages, is one of the most devastating diseases in history, having killed around 100million people in the 14th century.

An old photo of a human-sized bat in the Philippines has resurfaced on Twitter, puzzling social media users.

On June 24, a Twitter user with the handle @AlexJoestar622 shared an image of a giant golden-crowned flying fox hanging from a wire attached to the roof of a building.

“Remember when I told y’all about the Philippines having human-sized bats?” the user asked. “Yeah, this was what I was talking about.”
