A gene therapy that patients breathe in has been found to shrink lung tumours by inserting immune-boosting genes into surrounding cells

South Australia is proving to the world that relying largely on wind and solar energy with battery back-up is incredibly cheap, with electricity prices tumbling by 30 per cent in a year and sometimes going negative

Scientists have captured remarkable footage of the young of a mouse-sized marsupial, called a fat-tailed dunnart, making their way to their mother’s pouch soon after being born

Building the human story based on a few artefacts is tricky – particularly for wooden tools that don’t preserve well, or cave art that we don’t have the technology to date. Columnist Michael Marshall explores how we determine what came first in the timeline of our species

Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, according to new calculations

Networks of molecules in our body behave as though they have goals and desires. Understanding this phenomenon could solve the origins of life and mind in one fell swoop

Electric vehicle batteries are typically retired once they reach about 80 per cent of their original capacity, but they could be repurposed in electricity grids to balance out slumps in renewable generation

Setting a limit for global warming didn't succeed in galvanising climate action quickly enough – now we should focus on making the annual average temperature rise clear for all to see, says Bill McGuire

The lines worn into an engraved limestone object from the Netherlands are consistent with the idea that it was a Roman game board, according to an AI analysis

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity

Scientists have pinpointed a group of bacteria that consistently appear in high numbers in healthy people, suggesting that these could one day be targeted through diet or probiotics

People classed as “overweight” according to BMI can be perfectly healthy. But there are better measures of fat, and physicians are finally using them

A type of cognitive training that tests people's quick recall seems to reduce the risk of dementia, including Alzheimer's disease

Paul Erdős was one of the most prolific mathematicians to ever live, known for showing up at the door of others in the field and declaring they should host and feed him while they do maths together. His radical life should be immortalised by Hollywood in a comedy biopic, says columnist Jacob Aron

One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are getting a handle on how to attenuate or stop it completely

The first people to reach the Kitsissut Islands off the north-west coast of Greenland were Indigenous peoples, who crossed over 50 kilometres of treacherous water

The flow of ice at Pine Island Glacier in West Antarctica has sped up dramatically due to the disintegration of the ice shelf in front of it, and this could lead to faster sea level rise

Science funding cuts in the UK are expected to be a "devastasting blow" for physics research, affecting international projects such as particle detection experiments at CERN

When we exercise more, our bodies may compensate by using less energy for other things – especially if we eat less too
