It's the spin that makes the difference      (via sciencedaily.com)     Original source 

Biomolecules such as amino acids and sugars occur in two mirror-image forms -- in all living organisms, however, only one is ever found. Why this is the case is still unclear. Researchers have now found evidence that the interplay between electric and magnetic fields could be at the origin of this phenomenon.

Plastic recycling with a protein anchor      (via sciencedaily.com)     Original source 

Polystyrene is a widespread plastic that is essentially not recyclable when mixed with other materials and is not biodegradable. A research team has now introduced a biohybrid catalyst that oxidizes polystyrene microparticles to facilitate their subsequent degradation. The catalyst consists of a specially constructed 'anchor peptide' that adheres to polystyrene surfaces and a cobalt complex that oxidizes polystyrene.

Advanced artificial photosynthesis catalyst uses CO2 more efficiently to create biodegradable plastics      (via sciencedaily.com)     Original source 

A research team that had previously succeeded in synthesizing fumaric acid using bicarbonate and pyruvic acid, and carbon dioxide collected directly from the gas phase as one of the raw materials, has now created a new photosensitizer and developed a new artificial photosynthesis technology, effectively doubling the yield of fumaric acid production compared to the previous method. The results of this research are expected to reduce carbon dioxide emissions and provide an innovative way to produce biodegradable plastics while reusing waste resources.

Fundamental equation for superconducting quantum bits revised      (via sciencedaily.com)     Original source 

Physicists have uncovered that Josephson tunnel junctions -- the fundamental building blocks of superconducting quantum computers -- are more complex than previously thought. Just like overtones in a musical instrument, harmonics are superimposed on the fundamental mode. As a consequence, corrections may lead to quantum bits that are 2 to 7 times more stable. The researchers support their findings with experimental evidence from multiple laboratories across the globe.

Greetings from the island of enhanced stability: The quest for the limit of the periodic table      (via sciencedaily.com)     Original source 

Since the turn of the century, six new chemical elements have been discovered and subsequently added to the periodic table of elements, the very icon of chemistry. These new elements have high atomic numbers up to 118 and are significantly heavier than uranium, the element with the highest atomic number (92) found in larger quantities on Earth. This raises questions such as how many more of these superheavy species are waiting to be discovered, where -- if at all -- is a fundamental limit in the creation of these elements, and what are the characteristics of the so-called island of enhanced stability. In a recent review, experts in theoretical and experimental chemistry and physics of the heaviest elements and their nuclei summarize the major challenges and offer a fresh view on new superheavy elements and the limit of the periodic table.
