Dozens of bird species became more abundant in 93 urban centres across the US and Canada when covid-19 restrictions cut noise and pollution from traffic

A computer reconstruction of a small two-legged dinosaur suggests it ran more efficiently if it waggled its tail from side to side with every step

Around one third of all food produced globally goes to waste, the vast majority being thrown into landfill sites where it is left to rot away

Modelling suggests covid-19 hospitalisations in England could soon be as high as 7000 a day, but that is only one of several different possible scenarios

By studying DNA from people living in Polynesia, geneticists have worked out the order in which the islands – some thousands of kilometres apart– were populated

Millimetre-sized wireless sensors modelled after spinning or gliding seeds could be used to measure environmental factors such as pH

A 3D-printed material rolls itself up into a tube, becoming a  “4D-printed” robot that travels up hills when exposed to heat

The World Health Organization has released guidelines for strict limits on air pollution from cars, power stations and other sources. If countries adopt them, millions of deaths could be avoided

Black holes devour stuff and then shrivel away over billions of years. Explaining what happens to anything that falls in explodes our current theories of physics, says cosmologist Paul Davies

The latest coronavirus news updated every day including coronavirus cases, the latest news, features and interviews from New Scientist and essential information about the covid-19 pandemic

A record magnitude 5.9 earthquake struck in a remote part of Victoria, Australia, on 22 September, damaging buildings in Melbourne but not causing any fatalities

Over the past decade, minuscule land movements and strange chemical signals may have been clues that the Cumbre Vieja volcano on La Palma island was going to erupt

The Inspiration4 mission was the first orbital space flight to carry only private passengers and was mostly not broadcast publicly, a surprising change from the space agency transparency

A quantum computer made by researchers in China has outperformed classical computers, achieving what is known as quantum supremacy with a more complex quantum processor than ever before

Catnip contains a chemical that makes a highly effective insect repellent, but extracting it from plants is expensive. Now it can be produced using genetically engineered yeast

People who have had a stroke are generally given physiotherapy for around a month, but those who received extra treatment saw improved physical ability, against the received wisdom that only early intervention helps

The latest coronavirus news updated every day including coronavirus cases, the latest news, features and interviews from New Scientist and essential information about the covid-19 pandemic

Rising gas prices mean the UK is facing a difficult winter and some people are keen to point the blame at the shift to renewables – but relying on fossil fuels will always lead to cyclical crises

Five planetary nurseries have been chemically mapped in the most detail ever, showing hints of unexpected variety and high concentrations of the chemicals required for life

Quantum computers can simulate quantum circuits, which helps to speed up the design of new quantum processors
