Six full-body fossils of Ptychodus sharks have been formally analysed for the first time, revealing that they were fast swimmers that preyed on shelled creatures
Climate change’s effects on ocean water temperatures and salinity could shrink sonar detection ranges underwater and make it more challenging to spot submarines
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
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
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
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
What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore...
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
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
A site in Siberia has evidence of human presence 417,000 years ago, raising the possibility that hominins could have reached North America much earlier than we thought
Teams of staff usually return e-scooters to where they will be needed, but adapted scooters that can balance and stop themselves, and be controlled remotely, are a step towards autonomous ones that can take themselves wherever they have...
Last year’s marine heatwaves saw an unprecedented decline in the growth of phytoplankton and algae, which many animals in the oceans depend on for food
The 2010 Gulf of Mexico Deepwater Horizon oil spill, the largest accidental spill in history, released almost 100 million gallons of oil, causing significant pollution. A decade later, its long-term effects remain unclear. A study...
Cryptographers are scrambling to understand an algorithm that could undermine the mathematics behind next-generation encryption methods, which are intended to protect against quantum computers
In the foundations of a Maya temple, researchers found the charred bones of royal individuals – possibly evidence of a fiery ritual to mark the end of one dynasty and the beginning of another
Cloud seeding almost certainly did not play a significant role in the flooding on the Arabian peninsula this week – but the heavy rains may have been exacerbated by climate change
The jawbone of an ichthyosaur uncovered in south-west England has been identified as a new species, and researchers estimate that the whole animal was 20 to 25 metres long
One in five adults worldwide is living with fatigue. The general advice is to “do more” - but this isn’t the only solution to our exhaustion epidemic, says Amy Arthur
Caused by debris from a comet thought to originate in the Oort Cloud, the Lyrid meteor shower peaks this year on 22 April and is best viewed from the northern hemisphere, says Abigail Beall
Artist Matthew Attard turned to eye-tracking technology to generate a fresh take on images of ships carved by seafarers on chapels in Malta hundreds of years ago
Amid a deluge of dour TV shows about the end of the world, Fallout, based on the hit video games of the same name and set in the wastelands of 2296, stands out, says Bethan Ackerley
We know there is some connection between skin and gut health, but many assumed the gut was the one calling the shots. A new study suggests that the influence can go the other way
A computer intended to mimic the way the brain processes and stores data could potentially improve the efficiency and capabilities of artificial intelligence models
