In the welding field, however, some argue that a robot takeover might be beneficial, and even necessary.

Columbus startup Path Robotics believes AI is one solution to the shortage of skilled labor that plagues welding. Path boasts the “world’s first truly autonomous robotic welding system.” Conceived after 18 months in the basement of a foundry, its system identifies what needs to be welded, welds it and learns along the way.

Path Robotics CEO Andy Lonsberry said he and his brother, Alex Lonsberry, chief technology officer at Path Robotics, always wanted to start a business.

Earth’s oldest known material: Some zircons from Australia date back more than 4 billion years.

Crystals of the mineral zircon are rugged enough to survive the most violent geologic events.

How materials behave depends on the interactions between countless atoms. You could see this as a giant group chat in which atoms are continuously exchanging quantum information. Researchers from Delft University of Technology in collaboration with RWTH Aachen University and the Research Center Jülich have now been able to intercept a chat between two atoms. They present their findings in Science on May 28, 2021.

Atoms, of course, don’t really talk. But they can feel each other. This is particularly the case for magnetic atoms. “Each atom carries a small magnetic moment called spin. These spins influence each other, like compass needles do when you bring them close together. If you give one of them a push, they will start moving together in a very specific way,” explains Sander Otte, leader of the team that performed the research. “But according to the laws of quantum mechanics, each spin can be simultaneously point in various directions, forming a superposition. This means that actual transfer of quantum information takes place between the atoms, like some sort of conversation.”

There’s already a strong link between sleep and memory, and scientists have just found out more about how that relationship works: there are specific patterns of brain activity that open up windows on our past experiences, fixing them in our long-term memory.

These patterns involve the slow oscillations (SOs) of brain waves that normally accompany sleep, and the sharper sleep spindle bursts of activity that happen during dreamless slumber. It now seems that the precise way these two types of brain activity coordinate with each other makes a big difference in how well we remember something.

Our memories are essentially being reactivated during sleep via these two brain activity patterns, the researchers suggest, making us more likely to remember them. The stronger the reactivation, the more likely we are to be able to recall a memory later on.

There are now at least 16 malware families designed to compromise Pulse Secure VPN products.

It would be nice if they listed their diet.

Summary: Simple dietary changes and adopting lifestyle alterations, including improved sleep schedules, taking probiotics, and exercising, can reduce signs of biological aging by three years in just eight weeks, a new study reports.

Great new episode with guest Ben K.D. Pearce on how and why our own genetic code was able to form in Earth’s warm little ponds as early as 4.5 billion years ago. Please have a listen.

Guest Ben K.D. Pearce, a Ph.D student in astrophysics and astrobiology at McMaster University in Toronto, and an expert on the origins of life’s building blocks here on Earth. We discuss the idea that all the genetic components from which life emerged were incredibly readily available biogenically very early in Earth’s evolution. As early as 4.5 billion years ago. Pearce is part of a group making great strides in learning how this all may have happened in Earth’s very ancient warm little ponds.

The stuff of your cell walls forms in space before stars do — meaning the seeds of life could be abundant.

On the 91st Martian day, or sol, of NASA’s Mars 2020 Perseverance rover mission, the Ingenuity Mars Helicopter performed its sixth flight. The flight was designed to expand the flight envelope and demonstrate aerial-imaging capabilities by taking stereo images of a region of interest to the west. Ingenuity was commanded to climb to an altitude of 33 feet (10 meters) before translating 492 feet (150 meters) to the southwest at a ground speed of 9 mph (4 meters per second). At that point, it was to translate 49 feet (15 meters) to the south while taking images toward the west, then fly another 164 feet (50 meters) northeast and land.
