Climate change’s effects on ocean water temperatures and salinity could shrink sonar detection ranges underwater and make it more challenging to spot submarines

Amazon says it will create new jobs to replace roles taken over by machines, but it isn’t clear whether this will happen quickly enough

The balance of omega fatty acids in the food we eat affects our health. But what does the evidence say about claims you should be seeking to reduce omega-6 intake as well as boosting omega-3s?

AI can analyse satellite images to reveal the movements of dark ships in a shadow fleet that smuggles oil and other cargo from sanctioned countries such as Russia, Iran, Venezuela and North Korea

With severe climate impacts becoming more and more apparent, many scientists think we should explore ways to block out solar radiation, but doing so would be risky

Our blood sugar levels vary a lot from day to day, so results from continuous glucose monitors need to be interpreted with caution

A group of around 40 scientists signed a declaration calling for formal acknowledgement of consciousness in a range of animals, including insects and fish – but the evidence is still lacking

As work begins on building the US’s first high-speed rail service – linking Los Angeles to Las Vegas – analysts say the project could serve as a blueprint for similar projects across the country

In the 1920s, Erwin Schrödinger wrote an equation that predicts how particles-turned-waves should behave. Now, researchers are perfectly recreating those predictions in the lab

"Advanced recycling" promises to convert dirty, mixed waste plastic into brand new plastic time and time again. It is a major step towards creating a circular economy and fighting climate change

The finding that managed fires burn a much greater area than thought means we may be underestimating the increase in wildfires due to global heating

Forensic investigators can reliably measure drug and explosive residue using gels that lift fingerprint samples

Shading the planet by spraying aerosols into the stratosphere might stave off ice sheet collapse, modelling studies suggest, but we are running out of time

An Australian bull ant is the first animal known to use the patterns produced by polarised moonlight to navigate its environment

20 April is weed's unofficial holiday. In honour of the special day, we collected our answers to all your cannabis questions. This is the science of 420

It can be difficult to figure out how to move a spacecraft from one orbit to another, but a trick from knot theory can help find spots where shifting orbits becomes easy

Carbon storage calculations don’t always take into account the effects of animals – when they eat, defecate and die, they help store lots of carbon

By measuring how birds’ vocal muscles move while they are asleep and using a physical model for how those muscles produce sound, researchers have pulled songs from the minds of sleeping birds

Identical twins seem to experience more similar levels of pleasure when listening to music than non-identical twins, which suggests it has a genetic element

Curved wing tips inspired by the world's heaviest flying bird could enhance the efficiency of wind turbines by of 10 per cent, according to simulations
