NIST has made electron spin resonance useful for exploring tiny objects for the first time, potentially enabling the decades-old technique to spot defects on computer chip surfaces or view the workings of proteins on the surface of cells.

Archaeologists examining late period Mayan containers have identified nicotine traces from a codex-style flask, revealing the first physical evidence of tobacco use by ancient Mayans. The study published in Rapid Communications in Mass Spectrometry (doi: 10.1002/rcm.5339) reveals the flask is marked with Mayan hieroglyphics reading, “y-otoot ’u-may” (“the home of its/his/her tobacco”), making it only the second case to confirm that the text on the exterior of a Mayan vessel corresponds to its ancient use.

A new type of terahertz sensor, that is much faster than competing technologies used to detect and identify hidden objects, has been developed by scientists at the University of Warwick, UK.

As part of around €24.5 million in funding for the next three years, the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish one new Clinical Research Unit and nine new Research Units. As all DFG Research Units, the new units will collaborate interdisciplinarly and span multiple locations.

Among the new Research Units are three that may be of interest to readers (in alphabetical order by Host University).

Terahertz spectroscopy enables the measurement of fundamental magnetotransport details and provides basis for advanced nanoelectronics.

In this illustration, the Quantum Dot (QD) spectrometer device is printing QD filters—a key fabrication step. Other spectrometer approaches have complicated systems in order to create the optical structures needed. Here in the QD spectrometer approach, the optical structure, QD filters, are generated by printing liquid droplets. This approach is unique and advantageous in terms of flexibility, simplicity and cost reduction. Image: Mary O’Reilly

Super-eruptions are not the only type of eruption to be considered when evaluating hazards at volcanoes with protracted eruption histories, such as the Yellowstone (Wyoming), Long Valley (California), and Valles (New Mexico) calderas in the USA. There have been more than 23 effusive eruptions of rhyolite lava at Yellowstone since the last caldera-forming eruption ~640,000 years ago, all of similar or greater magnitude than the largest volcanic eruptions of the 20th century.

Europe is getting ready for its first unmanned visit to the surface of Mars. The first European Mars Rover on a joint mission of the American and European space agencies, NASA and ESA, will take off in 2018. The 250 kg Rover will roll over the surface of Mars at a speed of 100 m per hour. While doing so, it will inspect the surface and gather up ground and rock samples, some of them up to 2 m deep.

Recent hyperspectral imaging of Thomas Jefferson’s rough draft of the USA’s Declaration of Independence has clearly confirmed past speculation that Jefferson made an interesting word correction during his writing of the document, according to scientists in the Library of Congress’ Preservation Research and Testing Division (PRTD).

Elemental and isotope analysis of the metals in ancient artefacts such as the prutah shown here sometimes can pinpoint the places where the metal was mined. This can be combined with historical sources to determine when the coin was likely struck. Archaeologists can use the evidence to identify or narrow date ranges of historical significance.
