Terahertz radiation—the band of electromagnetic radiation between microwaves and visible light—has promising applications in security and medical diagnostics, but such devices will require the development of compact, low-power, high-quality terahertz lasers.
In a multinational collaboration, researchers from the Universities of Luxembourg, Ljubljana and Vienna have developed a new method to produce unique reflecting patterns that can be applied on valuable objects. As these patterns can’t be cloned or copied, they could be used to identify products unambiguously in order to avoid counterfeiting.

Knowledge of the minute details of the proteins that are linked to diseases is crucial if we are to discover therapeutic targets and thus pave the way for possible treatments. Such knowledge gains even more relevance when dealing with rare diseases that have received little attention and for which no treatments are available, such as the case of Kennedy’s disease.

Physicists at the National Institute of Standards and Technology (NIST) have “entangled” or linked together the properties of up to 219 beryllium ions (charged atoms) to create a quantum simulator. The simulator is designed to model and mimic complex physics phenomena in a way that is impossible with conventional machines, even supercomputers.
Super quantum simulator 'entangles' hundreds of ions Read More »
Scientists working for Murdoch University, the Wildlife Conservation Society, The Nature Conservancy, and other groups have good news about fishing closures established in Indonesia’s shark sanctuary: It’s good for sharks and other fish, all of which are more abundant within zones with fishing restrictions.
Fishing prohibitions produce more sharks along with problems for fishing communities Read More »
Analysis of oxygen isotopes in fossil teeth from red deer near the Adriatic Sea suggest that they migrated seasonally, which may have driven the movements of the Paleolithic hunter-gatherers that ate them, according a study published June 8, 2016 in the open-access journal PLOS ONE by Suzanne Pilaar Birch from University of Georgia, USA, and colleagues.

Researchers at the Georgia Institute of Technology looked at nearly 29 million tweets surrounding four recent Black Lives Matter (BLM) events to identify the social media patterns of its activists. They found that the community is unlike many other social movements because of its ability to bond over the course of many months.
The social media profile of the Black Lives Matter movement Read More »
Researchers at the Paul Scherrer Institute’s Swiss Light Source in Villigen, Switzerland, have developed a new design for X-ray spectrometers that eschews a commonly utilized component to lowers overall production costs and increase the efficiency of x-ray flux, which may lead to faster acquisition times for sample imaging and increased efficiency for the system.
Laboratory breakthrough may lead to improved X-ray spectrometers Read More »
Although proteins are usually electrically insulating, hair-like nanoscale filaments (called pili) on the surface of Geobacter bacteria exhibit metallic-like conductivity. To understand why pili are conductive, scientists from the University of Massachusetts at Amherst, Holy Cross, and Brookhaven National Laboratory recently used X-ray diffraction to analyze the structure of the filaments
Researchers from four U.S. universities are teaming up with dairy farms across the Northeast and Mid-Atlantic to study the effect of three different manure management techniques on preventing the occurrence and spread of antimicrobial-resistant bacteria, genes tied to resistance, and antibiotic residues—traces of antibiotics and the compounds they break down into.
