Understanding the “effort paradox” can help you reshape your relationship to exertion so that you commit to those hard but truly meaningful activities

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

New research into the moments between wakefulness and sleep could bring hope for insomniacs and even make us more creative problem-solvers

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

Ultra-fast pulses of laser light can be shaped into vortices similar to smoke rings – when chained together, they can carry enough information to transmit a simple image

A solar energy absorber that uses quartz to trap heat reached 1050°C in tests and could offer a way to decarbonise the production of steel and cement

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

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

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

A century ago, Albert Einstein suggested that the universe might contain ripples in space-time, known as gravitational waves – but then he changed his mind

An experiment to test distant particles’ ability to correlate their behaviour is one of the strongest pieces of evidence that classical ideas about reality are incorrect

A single ytterbium atom, cooled down to extreme temperatures and manipulated with laser beams, could reveal how gravity affects quantum objects

Experiments in a state-of-the-art wave tank suggest we have underestimated the potential size and power of rogue waves and the risk they pose to offshore infrastructure

Particles of light can spend "negative time" passing through a cloud of extremely cold atoms – without breaking the laws of physics

Light can be directed and steered around bends using a method similar to the way clouds scatter photons, which could lead to advances in medical imaging, cooling systems and even nuclear reactors

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

The second series of this show about Earth 66 million years ago is a joy to watch - but it inspires more than it informs. A little more science would have been nice

Climate researchers thought that current global average sea levels were the highest in more than 100,000 years, but new models suggest oceans just 6000 years ago may have been higher than at the beginning of the industrial revolution, and possibly even higher than today

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

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

This spectacular selection of images is taken from the winners of the Northern Lights Photographer of the Year competition, run by Capture the Atlas

Lightning strikes during volcanic eruptions could have provided nitrogen in a form that was needed by early life forms

An analysis of satellite observations has identified some extreme thunderstorms over the Indian Ocean and Gulf of Mexico with lightning flashes so frequent that the sky would appear continuously lit

Strange volcanoes called kimberlites bring diamonds up from Earth's depths. Scientists have always struggled to understand why they switched off millions of years ago – but perhaps they didn't

Computer simulations of how influenza A moves through human mucus found it is ideally configured to slide through the sticky stuff on its way to infecting cells

From the benefits of fermented foods to diets that promise a better hormone balance, there is a confusing array of dietary advice out there

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

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

Light can be directed and steered around bends using a method similar to the way clouds scatter photons, which could lead to advances in medical imaging, cooling systems and even nuclear reactors

One day, doctors might be able to 3D print copies of your organs in order to test a variety of drugs, thanks to a new technique that uses light and sound for rapid printing

A small world in the outer solar system appears to have volcanic activity possibly spurred by liquid water

Experiments show that illuminating the underside of a decoy seal reduces attacks by great white sharks, revealing a possible strategy to protect surfers and swimmers

SpaceX is preparing for the sixth test flight of Starship, the world's most powerful rocket. Next week's launch – if successful – will be the fastest turnaround yet

An annual accounting of CO2 emissions from burning fossil fuels and land use change finds no sign emissions will peak this year

Our hominin ancestors originated in Africa and the consensus is that they didn't leave there until about 1.8 million years ago, but stone tools found in Jordan challenge the idea

Most people are too risk-averse when it comes to life's biggest choices. Learning how to overcome the cognitive biases at play can help you make better decisions - with no looking back

Remote sensing, including lidar, reveals that the Amazon was once home to millions of people. The emerging picture of how they lived challenges ideas of human cultural evolution

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

Where do morals come from? In Animals, Robots, Gods, anthropologist Webb Keane argues imagination and differing senses of the world are key to discerning right from wrong

On a recent expedition, researchers braved summer storms in northern Greenland to learn the secrets of the ancient peoples who lived there 4500 years ago

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
