A recent experiment detailed in the journal Nature is challenging our picture of how electrons behave in quantum materials. Using stacked layers of a material called tungsten ditelluride, researchers have observed electrons in two-dimensions behaving as if they were in a single dimension—and in the process have created what the researchers assert is a new electronic state of matter.

“This is really a whole new horizon,” said Sanfeng Wu, assistant professor of physics at Princeton University and the senior author of the paper. “We were able to create a new electronic phase with this experiment—basically, a new type of metallic state.”

Our current understanding of the behavior of interacting in metals can be described by a theory that works well with two-and three-dimensional systems, but breaks down when describing the interaction of electrons in a single dimension.

We’ve been hearing a lot about synthetic skins designed for robotic hands, which would give the devices more human-like qualities. Well, scientists in Japan have gone a step further, by covering a robotic finger in a self-healing skin made from live human cells.

Led by Prof. Shoji Takeuchi, a team at the University of Tokyo started by building an articulated motor-driven robotic finger, capable of bending and straightening like its human counterpart. That finger was then submerged in a cylinder filled with a solution made up of collagen and human dermal fibroblast cells – these are the main components of our skin’s connective tissues.

Due to its natural properties, that solution shrank and conformed to the contours of the finger, forming a seamless hydrogel coating. Next, the scientists added a layer of human epidermal keratinocyte cells, which constitute 90 percent of our epidermis (the outermost layer of skin). These formed a moisture-retaining/water-resistant barrier on top of the gel, and gave the finger a more natural texture.

Conflux has specialized in making heat exchangers since its inception. Previously, the company collaborated with GKN to make its technology available in Europe. We interviewed CEO Michael Fuller, including on the 3DPOD. We also saw how the startup obtainined a series A round. The next step in Conflux’s development is the mass customization of its heat exchange products.

So far, Conflux offers individually designed heat exchangers to order. Usually for F1 teams and high-end industrial applications, these high-value heat sinks have all been unique and made specifically for their applications. That’s all well and dandy, of course, but it won’t really scale.

Now. the company has developed an annular water charge air cooler (WCAC) heat exchanger. WCAC heat exchangers are all the rage in automobiles now because they can potentially be more efficient in engine cooling than plate or other heat exchangers. WCACs could potentially improve mileage, top speed, and reduce A/C consumption in passenger cars. In racing, they probably won’t focus too much on the A/C consumption, but would be very pleased with the other potential advantages.

Numerous activities, including construction and demolition, mining and industrial activities, cooking and gardening, and others, generate a substantial amount of garbage. The amount of waste generated is directly proportional to consumption and production patterns.

In most cases, waste formation is the result of inefficient material utilization. Trends in the number, composition and impacts of these materials provide insight into the nation’s efficiency in using (and reusing) materials and resources. It also provides a better understanding of the effects of waste on human health and the environment.

According to surveys, 92 million tonnes of cloth are dumped as garbage each year worldwide. Estimates predict that this figure will likely exceed 130 million tonnes by 2030. When 200 tonnes of water used to make a single tonne of fabric is considered, it becomes clear that the end-to-end processes of the garment industry are severe threats to environmental initiatives.

NASA said it was interested in UAPs from a security and safety perspective. There was no evidence UAPs are extraterrestrial in origin, NASA added. The study will begin this fall and is expected to take nine months.

The team will gather data on “events in the sky that cannot be identified as aircraft or known natural phenomena — from a scientific perspective,” the agency said.

Scientists who study the cosmos have a favorite philosophy known as the “mediocrity principle,” which, in essence, suggests that there’s really nothing special about Earth, the sun or the Milky Way galaxy compared to the rest of the universe.

Now, new research from CU Boulder adds yet another piece of evidence to the case for mediocrity: Galaxies are, on average, at rest with respect to the . Jeremy Darling, a CU Boulder astrophysics professor, recently published this new cosmological finding in The Astrophysical Journal Letters.

“What this research is telling us is that we have a funny motion, but that funny motion is consistent with everything we know about the —there’s nothing special going on here,” said Darling. “We’re not special as a galaxy or as observers.”
