##### CALET Makes First Direct Measurements of Cosmic Ray Electrons up to 3 TeV in Space

##### CALET (CALorimetric Electron Telescope), a Japan-Italy-US experiment on the International Space Station (ISS), has successfully carried out a high-precision measurement of the cosmic ray electron spectrum up to 3 tera electron volts (TeV). This experiment, based on two years of data taken on the Exposed Facility on the ISS, is the first to make direct measurements of such high energy electrons in space. The CALET team published its first results in Physical Review Letters November 1 (O. Ariadne et al., Physical Review Letters 119, 181101, 2017). The measured spectrum provides a hint of a feature in the high energy spectrum that may be due to a nearby high energy source (e.g., a pulsar) or the annihilation of dark matter particles. CALET expects to take data on the ISS for an additional 3 years, and increase its current statistics by approximately a factor of 6. Read More

##### Kristina Launey published a book "Emergent Phenomena in Atomic Nuclei from Large-Scale Modeling: A Symmetry-Guided Perspective"

##### This book is a unique collection of reviews that discuss emergent phenomena in the world of protons and neutrons, and that of quarks and gluons, as viewed from first principles, microscopic considerations, and analysis of experimental data. A special theme resonates throughout the book: the important role of symmetries, exact and approximate, in exposing emergent features and guiding large-scale nuclear modeling, such as Lattice Quantum Chromodynamics, Effective Field Theory, Ab Initio Models, Quantum Monte Carlo Methods, and Density Functional Theory.

##### The Laser Interferometer Gravitational-wave Observatory, or LIGO, has made a third detection of gravitational waves, which are ripples in space and time, demonstrating that a new window in astronomy has been firmly opened. As was the case with the first two detections, the waves were generated when two black holes collided to form a larger black hole.

##### Jorge Pullin co-edited a book "Loop quantum gravity: the first 30 years"

##### Jorge Pullin has co-edited with Abhay Ashtekar, the Eberly Chair of Physics at the Pennsylvania State University, the volume "Loop quantum gravity: the first 30 years". It includes eight chapters by young emerging leaders of the field providing a snapshot of its state of the art, including one by LSU's Ivan Agullo and Parampreet Singh. The book is part of the series that World Scientific Publishing Co. of Singapore is putting out to celebrate the 100 years of Einstein's General Theory of Relativity. According to the publisher, It will include "two dozen excellent monographs written by top-notch authors from the international gravitational community". Read more

**Mark Wilde's Second Edition of his book "Quantum Information Theory" has been published. **Developing many of the major, exciting, pre- and post-millennium developments from
the ground up, this book is an ideal entry point for graduate students into quantum
information theory. Significant attention is given to quantum mechanics for quantum
information theory, and careful studies of the important protocols of teleportation,
superdense coding, and entanglement distribution are presented. In this new edition,
readers can expect to find over 100 pages of new material, including detailed discussions
of Bell's theorem, the CHSH game, Tsirelson's theorem, the axiomatic approach to quantum
channels, the definition of the diamond norm and its interpretation, and a proof of
the Choi–Kraus theorem. Discussion of the importance of the quantum dynamic capacity
formula has been completely revised, and many new exercises and references have been
added. This new edition will be welcomed by the upcoming generation of quantum information
theorists and the already established community of classical information theorists.** Read more **
