New method for precisely identifying and treating fractures.
You’ve injured your knee. A doctor straps a listening device to it, and the noises you hear coming out of it are cringe-worthy. “Crackle! Krglkrglkrgl! Snap!”

In the last few years, hundreds of contained “nano” satellites known as CubeSats have been launched in low Earth orbit for many purposes, including for collecting targeted scientific data. Federal agencies such as NASA and the National Science Foundation are exploring the potential of these highly affordable satellites in advancing research goals.
A new report from the National Academies of Sciences, Engineering, and Medicine concludes that CubeSats have demonstrated usefulness for scientific data gathering and can also augment – but not replace — the capabilities of large satellite missions and ground-based facilities. The report identifies examples of high-priority science goals that could be pursued through the use of CubeSats in areas such as solar and space physics, planetary science, and Earth science.
In order to continue building the capabilities of CubeSats for research, federal support is crucial, the report says, which identifies several steps NASA and NSF should take to ensure that CubeSats reach their full potential.
Biography:
Stuart Russell received his B.A. with first-class honours in physics from Oxford University in 1982 and his Ph.D. in computer science from Stanford in 1986. He then joined the faculty of the University of California at Berkeley, where he is Professor (and formerly Chair) of Electrical Engineering and Computer Sciences and holder of the Smith-Zadeh Chair in Engineering. He is also an Adjunct Professor of Neurological Surgery at UC San Francisco and Vice-Chair of the World Economic Forum’s Council on AI and Robotics. He has published over 150 papers on a wide range of topics in artificial intelligence including machine learning, probabilistic reasoning, knowledge representation, planning, real-time decision making, multitarget tracking, computer vision, computational physiology, and global seismic monitoring. His books include “The Use of Knowledge in Analogy and Induction”, “Do the Right Thing: Studies in Limited Rationality” (with Eric Wefald), and “Artificial Intelligence: A Modern Approach” (with Peter Norvig).
Abstract:
Autonomous weapons systems select and engage targets without human intervention; they become lethal when those targets include humans. LAWS might include, for example, armed quadcopters that can search for and eliminate enemy combatants in a city, but do not include cruise missiles or remotely piloted drones for which humans make all targeting decisions. The artificial intelligence (AI) and robotics communities face an important ethical decision: whether to support or oppose the development of lethal autonomous weapons systems (LAWS).
In a blog post today, Uber showed off the self-driving car that’s been stealthily cruising around Pittsburgh. The car is a hybrid Ford Fusion and is currently in early stages of safety testing. This particular Uber test vehicle was first spotted almost a year ago by local Pittsburgh media, but this is Uber’s first acknowledgement of such tests.
Uber and Google (among others) have been racing to be the first to develop self-driving taxis for over a year now. Uber “cleaned out” Carnegie Mellon and the National Robotics Engineering Center to be part of its Advanced Technology Center in Pittsburgh, the research arm responsible for developing this “look ma, no hands” technology. This heavy hiring out of Carnegie Mellon could give Uber a big boost. The Pittsburgh-based university considers itself the birthplace of self-driving cars, and it probably is. CMU researchers were testing autonomous vehicles before Google even existed.
In March, Uber also joined a coalition, this time in partnership with Google, to advocate for self-driving adoption.

Pressure is on DARPA by US Military to speed up on completing the soft Exosuit.
The clothing-like Soft Exosuit has been described as a “Wearable Robot” by the U.S. Defense Advanced Projects Research Agency (DARPA) that’s commissioning universities and research institutions to advance this military technology. The DARPA Soft Exosuit is part of the agency’s Warrior Web program.
A prototype Soft Exosuit had a series of webbing straps around the lower half of the body with a low-power microprocessor and a network of flexible strain sensors. These electronics act as the “brain” and “nervous system” of the Soft Exosuit. They continuously monitor data signals, including suit tension, wearer position (walking, running, crouched) and more.

Today’s emergence of nano-micro hybrid structures with almost biological complexity is of fundamental interest. Our ability to adapt intelligently to the challenges has ramifications all the way from fundamentally changing research itself, over applications critical to future survival, to posing small and medium as well as truly globally existential dangers.
The fabrication of a prototype tissue with functional properties close to natural tissues is crucial for effective transplantation. Tissue engineering scaffolds are typically used as supports that allow cells to form tissue-like structures essentially required for the correct functioning of the cells under the conditions close to the three-dimensional tissue.
Scientists of the Bionanotechnology Lab at Kazan Federal University combined biopolymers chitosan and agarose (polysaccharides) and gelatine protein to produce tissue engineering scaffolds and demonstrated the enhancement of mechanical strength, higher water uptake and thermal properties in chitosan-gelatine-agarose hydrogels doped with halloysite.
Chitosan, a natural biodegradable and chemically versatile biopolymer, has been effectively used in antibacterial, antifungal, anti-tumour and immunostimulating formulations. To overcome the disadvantages of pure chitosan scaffolds such as mechanical fragility and low biological resistance, chitosan scaffolds are typically doped with other supporting compounds that allow for mechanical strengthening, thus yielding composite biologically resistant scaffolds.

Quantum future discussed at London’s Royal Society Conference.
By Tushna Commissariat
Not a week goes by here at Physics World that we don’t cover some advance in quantum mechanics – be it another step towards quantum computing or error correction, or a new type of quantum sensor, or another basic principle being verified and tested at new scales. While each advance may not always be a breakthrough, it is fair to say that the field has grown by leaps and bound in the last 20 years or so. Indeed, it has seen at least two “revolutions” since it first began and is now poised on the brink of a third, as scientific groups and companies around the world race to build the first quantum computer.

Robotics with grace — hmmm.
A new type of hydrostatic transmission that combines hydraulic and pneumatic lines can safely and precisely drive robot arms, giving them the delicacy necessary to pick up an egg without breaking it.
You are really starting to see the shape of the Singularity, ever more clearly, in the convergence of so many engineering and scientific discoveries, inventions, and philosophical musings.
I can say, without a doubt, that we are all living in truly extraordinary times!
