Over the past 150 years, the rise in Caesarean sections and changes in diet could have led to smaller pelvises among women – which may make vaginal birth more difficult but could also reduce common conditions associated with childbirth

A simulation of the "aerial screw" designed by Leonardo da Vinci in 1480 suggests it would use less power than modern drone rotors to generate the same lift, and make less noise too

A high-speed crash between two dwarf galaxies might explain a unique feature in space – and provide useful information on dark matter

Our climate seems to be more sensitive to greenhouse gas emissions than some researchers had hoped, meaning the world will have to up its decarbonisation efforts

Humans established a wild population of brown forest wallabies in the Raja Ampat Islands thousands of years ago for their meat and fur in one of the earliest known species translocations

We're a step closer to two men being able to have genetic children of their own after the creation of fertile mice by putting two sperm cells in an empty egg

In just 10 hours of observing the night sky, the powerful new telescope detected more than 2000 new asteroids, including a few that will pass near Earth

Drone footage has captured killer whales breaking off stalks of kelp and rubbing the pieces on other orcas, a rare case of tool use in marine animals

What are quantum particles doing before we measure them? Getting to grips with this century-old debate takes us to the heart of whether there is an objective reality

Astronomers have been trying to detect atmospheres on planets orbiting TRAPPIST-1, but bursts of radiation from the star make this challenging

We have discovered legions of strange particles that seem to only have a ghostly existence inside materials. Even so, they are the basis of much modern technology - so are they actually real?

Two life forms living together helped spark the evolution of all complex life. By learning to appreciate this process more fully, we might be able to harness it to heal our planet too

From four-dimensional hexagons to the mind-bending amplituhedron, geometrical shapes are wilder than we learn at school - and they are a crucial tool for understanding reality

From acquaintances to besties, our relationships fall on a wide continuum. Research into the ingredients for meaningful and lasting connections can help you strengthen them

Geoengineering comes in many forms and the risks and potential benefits vary widely. But many researchers now feel it’s time to investigate this controversial idea

There’s an argument rumbling about why our ancestors evolved language. And surprisingly, one of the possible explanations has nothing to do with communication

Conditions in our little pocket of the universe seem to be just right for life - and the much-debated anthropic principle forces us to wonder why

All of us hold metaphysical beliefs, whether we realise it or not. Learning to question them is spurring progress on some of the hardest questions in physics

There is mounting evidence that even surprisingly simple animals, like invertebrates, have a level of consciousness - but not in the way you might think

Concepts like the “growth mindset” are much misunderstood. But learn to cultivate certain beliefs about your future potential, and evidence suggests it really can foster success and bring health benefits
