- Lead becomes stronger than steel under extreme pressures | Under normal conditions, lead is relatively soft, easily scratched with a fingernail. But when compressed under extreme pressures, it becomes hard and strong —even stronger than steel, scientists report in 'Physical Review Letters, Vol. 123' https://www.sciencenews.org/article/lead-becomes-stronger-than-steel-under-extreme-pressures 134 comments science

- To mark the passing of Stephen Hawking, they gathered together and made free to read his 55 papers in Physical Review D and Physical Review Letters. They probe the edges of space and time, from "Black holes and thermodynamics” to a "Wave function of the Universe." https://journals.aps.org/collections/stephen-hawking 12 comments technology
- The collision of two neutron stars formed a black hole and simultaneously solved several cosmic mysteries, researchers announced. More than 30 papers have been published so far in five journals — Physical Review Letters, Science, Nature, Nature Astronomy and Astrophysical Journal Letters. http://www.nature.com/news/colliding-stars-spark-rush-to-solve-cosmic-mysteries-1.22829 3 comments science
- On the road to creating an electrodeless spacecraft propulsion engine - headway on research towards creating an electrodeless plasma thruster used to propel spacecraft by researchers from Tohoku University published in Physical Review Letters. http://www.tohoku.ac.jp/en/press/electrodeless_spacecraft_propulsion_engine.html 17 comments space
- Scientists just took a major step towards achieving nuclear fusion. The new technique works by decelerating runaway electrons. This is done by injecting heavy ions, such as argon or neon in the form of gas or pellets, into the reactor. Study published today in Physical Review Letters. http://www.wired.co.uk/article/nuclear-fusion-closer 248 comments science
- The “chicken or egg” paradox was first proposed to describe the problem of determining cause-and-effect. Now, physicists show that, as far as quantum physics is concerned, the chicken and the egg can both come first. This is called `indefinite causal order’, as reported in Physical Review Letters. https://www.uq.edu.au/news/article/2018/09/quantum-weirdness-chicken-or-egg%E2%80%99-paradox 211 comments science
