We tend to think of Mars as similar to Earth, and in many ways that is true. It's relatively small and rocky. It has an atmosphere and recognisable geological features. We can identify the composition of its rocks, study its weather patterns, and d

The day the US mourned reaching a tragic milestone - 100,000 novel coronavirus deaths - people on the other side of the world in New Zealand celebrated a much more hopeful one: No new coronavirus cases over the prior five days.

An area near Yellowstone National Park has been struck by nearly a dozen earthquakes on Friday, according to the US Geological Survey.

Mars - glorious, dusty, complex Mars - may once have been even more dazzling. New research provides even more evidence that a rubbly ring once circled the Red Planet.

So much of our everyday tech runs on batteries, the importance of lithium-ion rechargeables cannot be overstated. But they are expensive to produce, with difficult-to-source materials.

Superspreader events, in which one person infects a disproportionately large number of others, are the primary means by which the coronavirus spreads, new preprint research suggests.

Russia on Thursday intensified efforts to clean up a major fuel spill that environmentalists say is the worst such accident in the Arctic, as investigators made their first arrest.

Thanks to rapid advances in technology, prosthetic limbs and artificial organs are pushing past the limits of what nature provides us. It's now blood's turn for a boost, with researchers finding a new way to mimic the tissue that carries oxygen.

Melting permafrost, suspected by Russia of being behind an unprecedented fuel spill that has polluted huge stretches of Arctic rivers, is a time bomb threatening health and the environment, and risks speeding up global warming.​

It sounds like something from a sci-fi movie, but the newly revealed Shadow-Effect Energy Generator (SEG) is a real prototype device. The fascinating concept could help us to transform the way renewable energy is generated indoors.

Editor's update: New Zealand has "eliminated" COVID-19 "for now", Prime Minister Jacinda Ardern has declared, announcing the nation will move to alert level 1 from midnight on June 8, lifting all requirements for social distancing and restrictions

For the second time ever, astronomers have found a fast radio burst (FRB) that repeats on a regular, predictable cycle. This could mean that - at least in some cases - the wild unpredictability of mysterious deep-space FRBs could actually be a prob

Some chimpanzees might be growing hard-hearted with age. A curious little bone has been found forming in the heart tissue of several chimpanzees, according to a newly published study.

By this time next year, NASA expected to have a new observatory in orbit, one that would make the Hubble Space Telescope look like a kid's toy. Unfortunately, we will need to wait a little longer for the next generation of stunning space photograp

An ancient giant crocodile may have once walked on only two legs, its tail held proudly in the air, its feet rolling heel-to-toe, not unlike our own.

Two people with beta thalassaemia and one with sickle cell disease no longer need blood transfusions after their blood stem cells were gene edited and put back in their bodies

This is fascinating.
