When it comes to exercise, more isn't necessarily better – and we're now discovering the ideal dose for better health

More and more parents are choosing to only have one child. Here’s what the evidence says about how growing up without siblings affects their personality traits and well-being

From artificial retinas to ageing mice, here are five of the most promising results from research performed on the ISS – and what they might mean for humans on Earth and in space

What anxiety actually is has puzzled scientists for decades. Now we are starting to figure out how it may arise from miscommunication between the body and the brain

Artificial intelligence has more in common with ants than humans, says Neil Lawrence. Only by taking a more nuanced view of intelligence can we see how machines will truly transform society

Male pattern baldness could soon be a thing of the past, with new hair loss treatments beginning to show tantalising results

Could the universe's missing matter be hiding in a "dark" extra dimension? We now have simple ways to test this outlandish idea - and the existence of extra dimensions more generally

What life is and how the mind works fall within the compass of one bold concept. But critics say that by attempting to explain everything, it may end up explaining nothing

The systems we use to produce food have many problems, from horrifying waste to their dependence on fossil fuels. Vaclav Smil explains how to fix them

You might have heard about plans to establish a self‑sustaining city on Mars. Here’s what life would really be like on the Red Planet

Two important barriers to a stable, powerful fusion reaction have been leapt by an experiment in a small tokamak reactor, but we don’t yet know if the technique will work in larger devices

The Large Hadron Collider is testing entanglement in a whole new energy range, probing the meaning of quantum theory – and the possibility that an even stranger reality lies beneath

Time loops have long been the stuff of science fiction. Now, using the rules of quantum mechanics, we have a way to effectively transport a particle back in time – here’s how

Strange solids called temporal metamaterials finally make it possible to investigate the controversial idea of quantum friction – and push special relativity to its limits

While time is relative, it still flows in one direction for every observer. We don’t yet understand why, but some physicists are looking for answers that invoke the evolution of entropy, says Chanda Prescod-Weinstein

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?

One hundred years ago, we discovered there were other galaxies beyond our own. Now, we might be on the verge of another discovery: that there are other universes

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

Photographer Enrico Sacchetti captures the power and potential of ITER, an international nuclear fusion experiment currently under construction in southern France

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

An ordinary-looking valley has a secret – each of its neighbours is 20 years removed in time. Scott Alexander Howard's debut is heartfelt and deeply enjoyable, says Emily H. Wilson

Commercially available quantum technology could let stock traders coordinate decisions to buy or sell nearly instantaneously using a technique called “quantum telepathy”

In an experiment simulating what happens deep in the interiors of planets, scientists have found that liquid can be compressed into ice crystals – even at extremely high temperatures

Could the universe's missing matter be hiding in a "dark" extra dimension? We now have simple ways to test this outlandish idea - and the existence of extra dimensions more generally

Researchers used a collection of charged atoms to create a quantum superposition of an exotic type of defect

Carbon emissions within the next 50 years could lead to a tipping point where large parts of the Greenland ice sheet melt over the next 10,000 years

Pressure on the San Andreas fault from a now-dried lake could have been sufficient to trigger past major earthquakes in California. The lake’s disappearance could explain why there have been no such quakes for nearly 300 years

Chris Packham's new BBC series, Earth, looks at significant moments in Earth's history, including anthropogenic climate change and biodiversity loss, "It's not a sixth mass extinction event that we're precipitating," he says, "it's a mass extermination event"

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

The Chicxulub impact 66 million years ago filled the sky with fine silicate dust, which blocked out sunlight and lingered for 15 years

Few volcanos come with more risk than Mexico's Popocatépetl, situated near Mexico City.  To mitigate danger, volcanologist Chiara Maria Petrone is trying to predict its next eruption

Several enormous craters left by explosions have been spotted in Siberia over the past 15 years, and a new explanation links them to hot gas – and climate change

Microbes that rapidly convert CO2 to rock could lock away the greenhouse gas in deep underground storage sites, such as depleted oil and gas reservoirs

Global warming means many of the world’s ancient rivers of ice will be gone within decades, threatening ecosystems that rely on their meltwater, a looming crisis that photographer Edward Burtynsky highlights in his work

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
