A new vibrant blue pottery pigment with less cobalt      (via sciencedaily.com)     Original source 

Whether ultramarine, cerulean, Egyptian or cobalt, blue pigments have colored artworks for centuries. Now, seemingly out of the blue, scientists have discovered a new blue pigment that uses less cobalt but still maintains a brilliant shine. Though something like this might only happen once in a blue moon, the cobalt-doped barium aluminosilicate colorant withstands the high temperatures found in a kiln and provides a bright color to glazed tiles.

An awkward family reunion: Sea monsters are our cousins      (via sciencedaily.com)     Original source 

The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study discovered that the hindbrain -- the part of the brain controlling vital functions like blood pressure and heart rate -- of both sea lampreys and humans is built using an extraordinarily similar molecular and genetic toolkit.

Kiss-and-tell: A new method for precision delivery of nanoparticles and small molecules to individual cells      (via sciencedaily.com)     Original source 

The delivery of experimental materials to individual cells with exactness and exclusivity has long been an elusive and much sought-after ability in biology. With it comes the promise of deciphering many longstanding secrets of the cell. A research team has now successfully shown how small molecules and single nanoparticles can be applied directly onto the surface of cells. In the study the scientists describe their technique as a ' kiss' (microkiss) -- an easy and cost-effective new method, unlocking new possibilities in single-cell science with a view towards next generation therapeutic applications.

An environmentally friendly way to turn seafood waste into value-added products      (via sciencedaily.com)     Original source 

Reduce, reuse, recycle, and repurpose: These are all ways we can live more sustainably. One tricky aspect of recycling, though, is that sometimes the recycling process is chemically intensive, and this is the case for recycling one of the world's most abundant materials -- chitin. Researchers have tackled this problem and found a way to sustainably recover chitin from seafood waste.

The cultural evolution of collective property rights      (via sciencedaily.com)     Original source 

Common pool resources comprise around 65 percent of Earth's surface and vast tracts of the ocean. While examples of successful governance of these resources exist, the circumstances and mechanisms behind their development have remained unclear. Researchers have developed a simulation model to examine the emergence, stability and temporal dynamics of collective property rights.

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.

Accelerating the discovery of single-molecule magnets with deep learning      (via sciencedaily.com)     Original source 

Single-molecule magnets (SMMs) are exciting materials. In a recent breakthrough, researchers have used deep learning to predict SMMs from 20,000 metal complexes. The predictions were made solely based on the crystal structures of these metal complexes, thus eliminating the need for time-consuming experiments and complex simulations. As a result, this method is expected to accelerate the development of functional materials, especially for high-density memory and quantum computing devices.

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.
