We may never know what lies beyond the boundaries of the observable universe, but the fabric of the cosmos can tell us whether the universe is infinite or not

People don't realise just how bad our antibiotic resistance problem is, says Jeanne Marrazzo, the top infectious disease specialist in the US

Your body is home to trillions of beneficial viruses crucial for a healthy microbiome. We may one day be able to tweak this "virome" to treat obesity and anxiety

Recent fossil finds suggest that big brains weren't an evolutionary asset to our ancestors but evolved by accident – and are likely to shrink again in the near future

Alex Lupsasca plans to extend Earth's largest telescope network beyond the atmosphere with a space-based dish. It could spot part of a black hole we've never seen before – and perhaps discover new physics

Devices that let people with paralysis walk and talk are rapidly improving. Some see a future in which we alter memories and download skills – but major challenges remain

There are secrets aplenty in a pot of honey – from information about bees' "micro-bee-ota" to DNA from the environment – that can help us fight food fraud and even monitor shifts in climate

The International Space Station will burn up and splash down into the Pacific sometime around 2030. What could possibly go wrong? And will we ever see anything like the ISS again?

With its particles in two places at once, quantum theory strains our common sense notions of how the universe should work. But one group of physicists says we can get reality back if we just redefine its foundations

Neuroscientists have been surprised to discover that the human brain is teeming with microbes, and we are beginning to suspect they could play a role in neurodegenerative disorders like Alzheimer's

To capture the clearest and most direct images of a “Wigner crystal”, a structure made entirely of electrons, researchers used a special kind of microscope and two pieces of graphene unusually free of imperfections

A contentious meeting of physicists highlighted concerns, failures and possible fixes for a crisis in condensed matter physics

ITER, a €20 billion nuclear fusion reactor under construction in France, will now not switch on until 2035 - a delay of 10 years. With smaller commercial fusion efforts on the rise, is it worth continuing with this gargantuan project?

The atoms within quasicrystals are arranged in repeating forms, but unlike ordinary crystals they have more complex symmetry. It turns out this makes them perfect for producing mazes

The gamma ray burst known as GRB221009A is the biggest explosion astronomers have ever glimpsed and we might finally know what caused the blast

Researchers were surprised to find that a very slightly curved object produces a more dramatic splash than a perfectly flat one

The hunt for particles of dark matter has been stymied once again, with physicists placing constraints on this mysterious substance that are 5 times tighter than the previous best

With its particles in two places at once, quantum theory strains our common sense notions of how the universe should work. But one group of physicists says we can get reality back if we just redefine its foundations

Marie Curie redefined the role of women in science by training a generation of “lab daughters” to have stellar careers, shows Dava Sobel's detailed and intimate new biography, The Elements of Marie Curie

The Impossible Man by Patchen Barss salutes Roger Penrose's groundbreaking work in physics and mathematics while challenging the idea that a genius should be exempt from ordinary obligations

Allowing for moves that create quantum superpositions makes a quantum version of a Rubik’s cube incredibly complex, but not impossible to solve

Semi-mythical "earthquake lights" may be accompanied by changes to Earth's magnetic field. Now researchers say these changes could be used to forecast major tremors

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

Once seen as miraculous, these days ice is no longer extraordinary. But in a winter season when Antarctic sea ice hit a historic low, it is clear we should cherish it more, says Max Leonard

The dynamics of how plants and animals change Earth is central to this last book in a trilogy by Other Minds author and "scuba-diving philosopher" Peter Godfrey-Smith

Antibiotics can reduce diversity in the gut microbiome, raising the risk of infections that cause diarrhoea - and the effects may last years

Radiocarbon dating and DNA analysis have revealed that a complete skeleton found in a 2nd-century cemetery is made up of bones from many people spanning thousands of years – but we don’t know who assembled it or why

A bird flu virus that has been circulating in dairy cattle for months has now been found in a pig in the US for the first time, raising the risk of the virus evolving to become more dangerous to people

Although the COP16 summit in Colombia ended with some important agreements, countries still aren’t moving fast enough to stem biodiversity loss

The Impossible Man by Patchen Barss salutes Roger Penrose's groundbreaking work in physics and mathematics while challenging the idea that a genius should be exempt from ordinary obligations

Blood tests have shown that about 7 per cent of workers on dairy farms that had H5N1 outbreaks had antibodies against the disease

Allowing for moves that create quantum superpositions makes a quantum version of a Rubik’s cube incredibly complex, but not impossible to solve

Seven major datasets used to train audio-generating AI models are three times more likely to use the words "man" or "men" than "woman" or "women", raising fears of bias

Samantha Harvey has won the UK's top fiction prize for a novel that takes place over 24 hours on the International Space Station

Eurasian reed warblers don’t just get a sense of direction from Earth’s magnetic field – they can also calculate their coordinates on a mental map

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

Can cultivating positive behaviours and tweaking our lifestyles lead to healthier, happier lives – even longer lives? Discover the daily choices that may make the difference in a fascinating new book

Underground tunnels created by lava flows provided humans with shelter for thousands of years beneath the hot desert landscape of Saudi Arabia

Recent fossil finds suggest that big brains weren't an evolutionary asset to our ancestors but evolved by accident – and are likely to shrink again in the near future

In an effort to understand ancient Neanderthal food preparation techniques, researchers butchered five wild birds using flint stone tools and roasted them

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

Radiocarbon dating and DNA analysis have revealed that a complete skeleton found in a 2nd-century cemetery is made up of bones from many people spanning thousands of years – but we don’t know who assembled it or why
