Dark matter may be the source of antimatter streaming past Earth

Two nearby powerful pulsars aren’t responsible for the stream of antimatter positrons snaking past Earth, so dark matter might be behind it after all

A ‘magic number’ of people walking across a bridge makes it sway

We thought walking in lock step made bridges sway, like London’s Millennium Bridge when it opened. But it turns out crowd size matters more than rhythm

Consciously quantum: How you make everything real

The idea that we create reality seems absurd. But an audacious new take on quantum theory suggests the fundamental laws of nature emerge from our own experiences

We’ve figured out how to ensure quantum computers can be trusted

Quantum computers will be useless if we can't trust their calculations. Now, two teams have programmed quantum systems to detect their own errors

Peek inside a gilded cage of liquid argon made to spot neutrinos

This huge shiny cube is just a 1/20th scale model of the planned DUNE neutrino detector. It will be filled with liquid argon to catch these elusive particles

Quantum code: why building the ultimate computer is the easy bit

After decades of hype, quantum computers are poised to prove their superiority over classical machines. Now the race is on to figure out what to do with them

Cosmic rays have revealed a new chamber in Egypt’s Great Pyramid

Particles from outer space have helped scientists uncover a hidden chamber within Egypt’s most famous pyramid, the first such finding in over a century

How learning to share cakes could help stop unfair US elections

The “I-Cut-You-Choose” method results in provably fair slices of cake. The same game theory approach can produce fairer voting districts in US states, too

AI physicists: The machines cracking the quantum code

We are all too easily bamboozled by the quantum world's complexity – now artificial intelligence is venturing where human minds fear to go

Light’s quantum weirdness survives after going to space and back

Photons act both like waves and particles, and their dual nature has now been seen even after bouncing them off a satellite in low Earth orbit

Why our ‘freakish’ galaxy has got cosmologists seriously worried

In the grand club of galaxies, the Milky Way is increasingly looking like an outlier. This is a looming challenge for cosmology, says Geraint Lewis

Hiding in plain sight: The mystery of the sun’s missing matter

A mass equivalent to 1500 Earths has vanished from the sun. Tracking it down could transform how we see the stars

Roadside barrier that folds like origami blocks traffic noise

Traffic noise has many frequencies, making it hard to suppress. A new barrier with movable folds can change its acoustic properties in response to traffic patterns

How to beat the bookies by turning their odds against them

Bookmakers use complex prediction models to set the odds of sporting outcomes in their favour – but a simple analysis of available odds can still give good returns

We can finally map the spiral arm on the far side of the galaxy

Using a jet of radio waves, astronomers have begun to map the other side of the Milky Way. Within 10 years we could have a complete map of the entire galaxy

It was always crazy to shoot for Mars before colonising the moon

Common sense is prevailing in human space exploration, and the moon is back as the place we need to colonise before a riskier trip to Mars, says Paul Marks

Culture picks: Read your way into (almost) any science subject

From gravitational waves to waves of flavour, Jonathon Keats surveys the best of the current crop of science writing

Most science papers turn out to be wrong. It’s time to fix that

Research findings often crumble under the microscope. Rows over the best way to fix this must end so we can stop trust in science crumbling too, says Robert Matthews

Light-filtering paint cools your home when exposed to hot sun

Laser cooling has been applied to paint, which could mitigate urban heat islands and solve the problem of how to cool objects in space

Nobel prizes would be better without all the fame and fortune

A Nobel prize brings big money and celebrity status for a few, but that's at odds with modern, collaborative science done for the greater good, says Geraint Lewis
