Chemists journey to Gobi region for samples, discover novel dye in textiles from Peru
Although searching for 3,000-year-old mummy textiles in tombs under the blazing sun of a western Chinese desert may seem more Indiana Jones than analytical chemist, two Boston University researchers recently did just that. Traveling along the ancient Silk Road in Xinjiang Province on their quest, they found the ancient fabrics – and hit upon a research adventure that combined chemistry, archaeology, anthropology, botany, and art.
The chemists, Richard Laursen, a professor in the Boston University Department of Chemistry, and Xian Zhang, a chemistry graduate student, have refined a technique that helps archaeologists and anthropologists identify the plant species that ancient people used to make fabric dyes. Their technique has not only provided researchers with a new, more powerful tool for analyzing previously known dye types, it also has led to the discovery of at least one never-before described dye. In addition, the BU chemists have started a catalogue of plant sample characteristics for use by dye researchers around the world.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
