The direction of cause and effect was brought into question for quantum objects more than a decade ago, but new calculations may offer a way to restore it

A new technique uses glowing molecules, laser light and microscopes to measure distances as minuscule as 0.1 nanometres – the width of a typical atom

A mathematical study finds that three definitions of what it means for entropy to increase, which have previously been considered equivalent, can produce different results in the quantum realm

Olivier Grunewald took this image of the Icelandic volcano's central crater filled with lava, forming a fiery lake of liquid rock

If humans still exist millions of years from now, they will face inhospitably warm conditions on a supercontinent centred at the equator. Most land mammals won't be able to survive

A better picture of the hidden landscape beneath the frozen surface of Antarctica could help us understand how the ice will respond to climate change

Two strange, high-density blobs buried more than a kilometre underground may have come from the ancient world Theia, which is thought to have slammed into Earth to create the moon

Iceland’s Fagradalsfjall volcano, located on the country’s south-west Reykjanes peninsula, has erupted after weeks of earthquake activity

Scientific bodies are due to make an official decision in the coming year about whether to declare a new geochronological unit precipitated by the impact of humans on Earth

Mysterious green sunsets were reported after the massive eruption of Krakatoa in 1883 – now simulations show how they were created and just how rare they are

Humans are drastically changing the planet and the Anthropocene is a useful tool to help us deal with that – so let's stop quibbling over definitions

Rapid erosion caused by a geological act of “piracy” tens of thousands of years ago may have raised Earth’s crust and elevated Mount Everest by as much as 50 metres

Diets that claim to control excess oestrogen or stress hormones are all the rage on Instagram and TikTok. They could be good for us, just not for the reasons claimed

Our metabolism's response to food is highly idiosyncratic and there are hints that tailoring our diet to these personal differences can deliver health benefits

Thanks to artificial intelligence, understanding animals may be closer than we think. But we may not like what they are going to tell us, says RSPCA chief executive Chris Sherwood

An off-the-shelf millimetre wave sensor can pick out the tiny vibrations made by a smartphone's speaker, enabling an AI model to transcribe the conversation, even at a distance in a noisy room

I have a confession to make. After taking a handful of autonomous taxi rides, I have gone from a hater to a friend of robot cars in just a few weeks, says Annalee Newitz

The health benefits of fermented food and drink have long been touted, but firm evidence in favour of kombucha, sauerkraut and kefir is surprisingly elusive

Fibres in wet wipes and clothes often make their way into soil - and natural versions could be more damaging than synthetic ones

The controversies surrounding football’s video assistant referee (VAR) system highlight our troubled relationship with uncertainty – and point to potential solutions

A stone wall nearly a kilometre long found under the Baltic Sea may have been built by ancient hunters to channel deer into a confined space

Birthrates are projected to have fallen below the replacement level, of 2.1 per woman, in more than three quarters of countries by 2050

Animal life on Earth existed for over half a billion years before hominins hit the scene – a complex combination of environmental changes, innovations in technology and competition may have led to us

Historians have claimed the people of Easter Island overexploited natural resources, causing a population crash, but new evidence suggests they lived sustainably for centuries

An arm bone from an ancient human that lived 700,000 years ago on the island of Flores is the smallest ever found from an adult hominin, adding a new piece to the puzzle of Homo floresiensis

The nearest source of the altar stone at the centre of Stonehenge has finally been identified – and it is at least 750 kilometres away in north-east Scotland

Ancient humans are said to have evolved to leave the trees, where our primate ancestors lived, in favour of open grassy savannahs – but we may have this idea wrong

New research is revealing that common sense is a lot more idiosyncratic than we thought, with important implications for tackling political polarisation and the future of AI
