Spintronics: A new path to room temperature swirling spin textures

Posted by in categories: materials, particle physics

In some materials, spins form complex magnetic structures within the nanometer and micrometer scale in which the magnetization direction twists and curls along specific directions. Examples of such structures are magnetic bubbles, skyrmions, and magnetic vortices.

New research could enable more—and more efficient—synthesis of metastable materials

Posted by in category: materials

Ion exchange is a powerful technique for converting one material to another when synthesizing new products. In this process, scientists know what reactants lead to what products, but how the process works—the exact pathway of how one material can be converted to another—has remained elusive.

Evolution’s recipe book: How ‘copy paste’ errors led to insect flight, octopus camouflage and human cognition

Posted by in category: evolution

Seven hundred million years ago, a remarkable creature emerged for the first time. Though it may not have been much to look at by today’s standards, the animal had a front and a back, a top and a bottom. This was a groundbreaking adaptation at the time, and one which laid down the basic body plan which most complex animals, including humans, would eventually inherit.

The inconspicuous animal resided in the ancient seas of Earth, likely crawling along the seafloor. This was the last common ancestor of bilaterians, a vast supergroup of animals including vertebrates (fish, amphibians, reptiles, birds, and mammals), and invertebrates (insects, arthropods, mollusks, worms, echinoderms and many more).

To this day, more than 7,000 groups of genes can be traced back to the last common ancestor of bilaterians, according to a study of 20 different bilaterian species including humans, sharks, mayflies, centipedes and octopuses. The findings were made by researchers at the Centre for Genomic Regulation (CRG) in Barcelona and are published today in the journal Nature Ecology & Evolution.

New study sheds light on the structure and evolution of an enzyme in psychoactive fungi

Posted by in category: evolution

An international research team has investigated the biosynthesis of psilocybin, the main ingredient of hallucinogenic mushrooms. They gained new insights into the structure and reaction mechanism of the enzyme PsiM. It plays a key role in the production of psilocybin. The results of the study were published in the journal Nature Communications.

Kia has the ‘secret sauce’ for affordable EVs in the US

Posted by in categories: sustainability, transportation

Cheaper electric vehicles are on the way, and Kia believes it has an advantage. With its own “secret sauce,” Kia is moving to launch a series of affordable EVs in the US.

“We’re ahead of most, and we’re trying to rush out ahead because our technology will be more evolved,” Kia America COO Steve Center told Automotive News.

Kia revealed a new range of low-cost EVs during its first annual EV Day in October, including the EV2, EV3, EV4, and EV5.

First Fractal Molecule in Nature Assembles Into a Sierpinski Triangle And We Don’t Know Why

Posted by in category: space

From the spiral arms of galaxies to microscopic snow crystals, nature seems to fall into fractal-like patterns that repeat in increasingly smaller increments. No matter how small you go, parts of the pattern still resemble the whole.

One exception appears to be molecules, which have not been known to exhibit self-similarity at changing scales. That is, until now.

Researchers from Germany, Sweden, and the UK have discovered an enzyme produced by a single-celled organism that can arrange itself into a fractal – not just any fractal, but a repeating pattern of triangles known as a Sierpiński triangle.
