Mystery honeycombs in rock may be created by water and salt

Many rocks are covered with circular hollows that look like honeycomb, and now we may finally understand how these strange formations come into existence

Bats’ hairy tongues are perfectly adapted for lapping up nectar

If you're a greedy bat, it helps to have a hairy tongue. The hairs will ensure that you can slurp as much nectar as possible from flowers into your mouth

Quantum time machine: How the future can change what happens now

The idea that the future can influence the past may finally explain the inherent randomness of quantum theory and bring it in line with Einstein's space-time

A single atom is visible to the naked eye in this stunning photo

This photo shows a strontium atom suspended in electric fields. A blue laser makes the tiny dot visible, though it’s only 215 billionths of a millimetre wide

Suns and daughters: The family tree that may unite all the stars

The chemical make-up of stars tells us a lot about their explosive family history. Unlocking those secrets could reveal how the galaxy got its shape

SpaceX’s rocket test wasn’t a complete success – but was close

SpaceX's historic launch wasn't 100 per cent successful, but there is now a Tesla Roadster floating on an orbit between Mars and Jupiter

Ghostly images show the history of X-ray tubes

Some of the first machines ever built to emit X-rays have been given a taste of their own medicine - and these ghostly images are the result

Shrinking black holes avoid paradox by oozing hidden information

As black holes evaporate, they release particles that may carry more information than we thought, so black holes may not break the laws of physics after all

Sound waves may be able to trigger earlier tsunami warnings

When an earthquake sets off a tsunami, it releases speedy sound waves that could give us early warning. But they still can’t predict the size of the tsunami  

Neutrinos may have more kinds of cosmic sources than we thought

Trillions of neutrinos hit Earth each day, but we don’t know where they come from. A new model shows how many may be made in our atmosphere, our galaxy and beyond

So long, suckers: Where have all the black holes gone?

The universe is well-stocked with black holes large and small, but none in medium. Strange dwarf galaxies might hold the answer

Clever maths will stop hackers spying on the quantum internet

Quantum communications are theoretically secure, but keeping a complex quantum network unhackable in practice is more difficult than expected

Mathematician set to publish ABC proof almost no one understands

After a five year struggle, Shinichi Mochizuki’s epic ABC proof may finally appear in a journal, but it is still not clear if mathematicians understand his work

Good news: one form of air pollution may be falling in Europe

Levels of nitrogen dioxide in European city air rose throughout the 2000s but seem to have reached a peak in 2010 – suggesting Europe might get cleaner air sooner than expected

We’ve found a bunch of dwarf galaxies we thought didn’t exist

The missing dwarf galaxies around the Milky Way have been found. Their existence means dark matter could be made of particles that are warmer than we expected

How a fiery matter-antimatter union may lead to limitless energy

A weird, self-destructive blend of opposite stuffs briefly reigned at the birth of the universe. Recreating it could crack the nut of nuclear fusion

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
