Clouds of bubbles in low-gravity environments behave differently from those on Earth, owing to their reduced buoyancy. A paper in Soft Matter reports a study of the behaviour of bubble clouds in a vessel in freefall.
A Nature Astronomy paper finds that distributing peer review amongst grant applicants, aided by a machine-learning algorithm, can lead to more democratic decisions and provide more detailed feedback.
A paper in Communications Physics catalogues the swarming behaviour of Bacillus subtilis as a function of the colony density and the cell aspect ratio, contributing to the picture of how physical properties of cells affect their motion in groups.
An Advanced Materials paper presents a new type of device that generates polarized single photons without the need for high magnetic fields or cryogenic temperatures.
Experiments published in Physical Review Letters on the separation dependence of gravitational attraction find results consistent with Newton’s law of gravitation for separations between 52 μm and 3 mm.
As the number of COVID-19 cases continues to grow around the world, physicists — many of whom rely on international travel and collaborations — are adapting.
Although the ultimate fate of the the International Linear Collider, a future 250 GeV linear accelerator based on superconducting radiofrequency technology, is yet to be decided, research and development efforts are proceeding undeterred.
Over the next 5 years the Dark Energy Spectroscopic Instrument (DESI) will be mapping 35 million galaxies and 2.4 million quasars trying to uncover the mystery of dark energy.
A Nature Communications paper reports a new model describing friction in layered materials and explaining previous results that were in apparent contradiction with one another.
A PNAS paper presents a neural network of physics publications that can identify trends and provide suggestions for future research directions in quantum physics
A Nature Physics paper reports a hardware-independent variational quantum algorithm that can be used to verify sampling and characterize unknown physical processes.
