A set of large, distinctive footprints suggest a raptor dinosaur that lived in East Asia 96 million years ago grew to a length of 5 metres
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
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
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 to go
Set in an English manor in 1890, Botany Manor is a video game that places you in the shoes of a botanist working on a herbarium of forgotten flora
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
Both a special diet that excludes “FODMAP” compounds and a low-carb high-fibre diet were effective
Cocaine and morphine hijacked neural responses in the brains of mice, which resulted in them consuming less food and water
The vertebrae of Vasuki indicus, a snake that lived 47 million years ago, suggest it could have been as long as 15 metres
Measurements of sulphur isotopes in Io’s atmosphere show that the moon may have been volcanically active for its entire lifetime
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
A mathematical model of a particle that remembers its past so that it never travels the same path twice produces stunningly complex patterns
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
Underground tunnels created by lava flows provided humans with shelter for thousands of years beneath the hot desert landscape of Saudi Arabia
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
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
Feedback pores over new research that suggests "robot-human boxing" would reduce brain injuries by reducing the number of live opponents involved
Millions of people experience symptoms many doctors dismiss as imaginary, but why? Caroline Crampton's moving first-person account is very revealing
Negative thinking is unpopular but it could drive more realistic efforts to limit harm from global warming
Can you see through deceiving data and beguiling stories? Read Alex Edmans's new book and take his card test to find out
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
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
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
Weeding robots can sometimes struggle to tell weeds from crops, but genetically modifying the plants we want to keep to make them brightly coloured would make the job easier, suggest a group of researchers
Investigations of the paradoxical link between tinnitus and hearing loss have revealed a hidden form of deafness, paving the way to possible new treatments
Up to 17 US states could be peppered with more than a trillion cicadas this spring, and though it has been a while since these two specific broods emerged at once, double broods are not that rare
