Life in a carbon-neutral world
Cities and countries around the world are aiming to become net carbon neutral within the next few decades. Kate Ravilious asks, what will day-to-day life look like in such a world?
COVID-19: how physics is helping the fight against the pandemic
With the world in the grips of the COVID-19 pandemic, Jon Cartwright investigates how physics-based techniques are helping scientists study viruses, including this latest novel coronavirus
Time crystals enter the real world of condensed matter
Peter Hannaford and Krzysztof Sacha ask whether we can realize condensed-matter phenomena exhibited by ordinary spatial crystals in the time dimension
Navigating the terahertz gap
The terahertz region of the electromagnetic spectrum is exploited less than its neighbouring wavelengths but plays a vital role in astronomy, as Sidney Perkowitz explains
Turning water into watts
The oceans seem like an obvious source of renewable energy, but there are huge technical and financial hurdles to harnessing their vast power. Stephen Ornes investigates
Double slits with single atoms
Andrew Murray describes a new variant of the classic Young's double-slit experiments, but this time using photoelectrons emitted via two different paths from rubidium atoms excited by infrared ...
The enduring enigma of the cosmic cold spot
Why does the cosmic microwave background have a strange patch that is much colder than expected? Syed Faisal ur Rahman looks at some possible explanations
Acoustics in architecture
Giving audiences a great listening experience is a complex mix of acoustics and architecture. But as Anna Demming explains, the challenges are even harder when revamping historic venues
The secret of the synchronized pendulums
Huygens was first to notice that pairs of linked pendulums can swing in synchrony. But as Jonatan Pena Ramirez and Henk Nijmeijer explain, mystery still surrounds the behaviour of synch...
