Entangled atoms cross quantum network from one lab to another      (via sciencedaily.com) 

Trapped ions have previously only been entangled in one and the same laboratory. Now, teams have entangled two ions over a distance of 230 meters. The nodes of this network were housed in two labs at the Campus Technik to the west of Innsbruck, Austria. The experiment shows that trapped ions are a promising platform for future quantum networks that span cities and eventually continents.

Amplified search for new forces      (via sciencedaily.com) 

In the search for new forces and interactions beyond the Standard Model, an international team of researchers has now taken a good step forward. The researchers are using an amplification technique based on nuclear magnetic resonance. They use their experimental setup to study a particular exotic interaction between spins: a parity-violating interaction mediated by a new hypothetical exchange particle, called a Z' boson, which exists in addition to the Z boson mediating the weak interaction in the standard Model.

Magnetic sandwich mediating between two worlds      (via sciencedaily.com) 

An international research team has developed a new method for the efficient coupling of terahertz waves with much shorter wavelengths, so-called spin waves. Their experiments, in combination with theoretical models, clarify the fundamental mechanisms of this process previously thought impossible. The results are an important step for the development of novel, energy-saving spin-based technologies for data processing.

Quantum physicists make major nanoscopic advance      (via sciencedaily.com)     Original source 

In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.

Ethical ancient DNA research must involve descendant communities, say researchers      (via sciencedaily.com) 

The analysis of ancient DNA allows scientists to trace human evolution and make important discoveries about modern populations. The data revealed by ancient DNA sampling can be valuable, but the human remains that carry this ancient DNA are often those of the ancestors of modern Indigenous groups, and some communities have expressed concerns about the ethics of sampling by outside parties. A group of scientists make the case for involvement of descendant communities in all aspects of the research process.

Smallpox has plagued humans since ancient Egyptian times, new evidence confirms      (via sciencedaily.com)     Original source 

Smallpox was once one of humanity's most devastating diseases, but its origin is shrouded in mystery. For years, scientific estimates of when the smallpox virus first emerged have been at odds with historical records. Now, a new study reveals that the virus dates back 2,000 years further than scientists have previously shown, verifying historical sources and confirming for the first time that the disease has plagued human societies since ancient times.

Jawbone may represent earliest presence of humans in Europe      (via sciencedaily.com) 

For over a century, one of the earliest human fossils ever discovered in Spain has been long considered a Neanderthal. However, new analysis from an international research team dismantles this century-long interpretation, demonstrating that this fossil is not a Neanderthal; rather, it may actually represent the earliest presence of Homo sapiens ever documented in Europe.
