Antibiotics wrapped in nanofibers turn resistant disease-producing bacteria into ghosts

Encapsulating antibiotics inside nanofibers, like a mummy inside a sarcophagus, gives them the amazing ability to destroy drug-resistant bacteria so completely that scientists described the remains as mere "ghosts".

Imaging the paintings under the paintings of the Old Masters

Speaking at the 241st National Meeting and Exposition of the American Chemical Society, an international team of scientists today described use of a new technique to see the paintings under the paintings of Rembrandt, Caravaggio, Rubens, and other 17th Century Old Master painters. The report was among almost two dozen studies presented as part of a symposium on chemistry and art titled "Partnerships and New Analytical Methodologies at the Interface of Chemistry and Art."

The quest for new materials: Can any insulator become topological?

Researchers at the Joint Quantum Institute (JQI) and the California Institute of Technology have shown that it may be possible to take a conventional semiconductor and endow it with topological properties without subjecting the material to extreme environmental conditions or fundamentally changing its solid state structure.

Researchers make first perovskite-based superlens for the infrared

Researchers have fabricated a superlens from perovskite oxides that are simpler and easier to fabricate than metamaterials, and are ideal for capturing light in the mid-infrared range, which opens the door to highly sensitive biomedical detection and imaging. It is also possible that the superlensing effect can be selectively turned on/off, which would open the door to highly dense data writing and storage.

Growing cells on 3D scaffolds

What is so fascinating about this method is that the cells are able to attach to special micrometre-sized "handles" on the scaffolds and nowhere else. The direct laser writing method used gives the researchers full control over the formation of cell adhesion sites and shape of the cells, which represents a major progress in the field of biomaterial engineering.
