Daniele Oriti’s pursuit of a theory of quantum gravity has led him to the startling conclusion that the laws of nature don’t exist independently of us – a perspective shift that could yield fresh breakthroughs

Discoveries from the genomes of the last Neanderthals are rewriting the story of how our own species came to replace them

Netflix’s Ancient Apocalypse peddles the idea that we have overlooked an extraordinary ancient civilisation. Flint Dibble explains why that is wrong, and why real archaeology is more exciting

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 discovery that a small blue blob of neurons, the locus coeruleus, controls your mode of thinking suggests ways to increase learning, creativity, focus and alertness

As more of us take up vaping and concerns rise about the long-term effects, we now have enough data to get a grip on the health impact – and how it compares to smoking

Physicists finally know whether black holes destroy the information contained in infalling matter. The problem is that the answer hasn’t lit the way to a new understanding of space-time

Most ingredients touted as the key to better health fail to live up to the hype but fibre bucks this trend, with benefits for the whole body, not just the gut

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

We get about a quarter of our calories from snacks and new research shows that this isn't necessarily bad for us. Done right, snacking can boost our health

From nuclear strikes to giant spikes, discover the systems in place to prevent a collision and test your decision-making to see if you could avoid a catastrophic impact

Extreme weather and a growing population is driving a food security crisis. What can we do to break the vicious cycle of carbon emissions, climate change and soaring food costs – or is it already too late?

A super-stretchy hydrogel can stretch to 15 times its original length and return to its initial shape, and could be used to make soft inflatable robots

A new equation shows a surprisingly simple relationship between pressure and the temperature needed to melt any solid substance into a liquid

Claudia de Rham thinks that gravitons, hypothetical particles thought to carry gravity, have mass. If she’s right, we can expect to see “rainbows” in ripples in space-time

Nobel prizewinning theoretical physicist Peter Higgs has died aged 94. He proposed the particle that gives other particles mass – now named the Higgs boson and discovered by the Large Hadron Collider at CERN in 2012

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

Researchers have used quantum light to create a magnetic field with a strength that is measured in imaginary numbers

Cosmological puzzles are tempting astronomers to rethink our simple picture of the universe – and ask whether dark matter is even stranger than we thought

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

From the vastness of the universe to the infinitesimal particles that comprise it, extremes of scale defy comprehension – and present a problem for physicists seeking a unified theory of everything

When I heard Stephen Hawking extol the mysteries of black holes, I knew theoretical physics was what I wanted to do. There is still so much to learn about these strange regions, says Chanda Prescod-Weinstein

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?

An experiment with a robot and gelatine determined that 65-micrometre-thick paper is the most prone to slicing our skin – but it can also make for a handy recyclable knife

Through science, we are striving for objective knowledge about the universe around us. But physicists increasingly believe achieving this will never be possible

Almost all the stars that will ever exist have already been born, and they have been around long enough for life to evolve on planets that orbit them

Research has found the universe is remarkably similar in structure to the human brain. But does this mean the cosmos has a consciousness of its own?

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

A subatomic particle called the muon caused waves when its experimental behaviour didn't align with a prediction based on the standard model. A new calculation might resolve the discrepancy – but some particle physicists are sceptical

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
