Unexplained gamma ray radiation coming from the edge of the Milky Way galaxy could be produced by self-annihilating dark matter particles – but the idea requires further investigation

The laws of thermodynamics don't accurately account for the complex processes in living cells – do we need a new one to accurately measure the ways living systems are out of equilibrium?

Hoverflies, often mistaken for bees and wasps, pollinate three quarters of our crops. Now we’re discovering we can train them to be even more efficient

See some of the winning entries for this year's Oceania Photo Contest, including Miesa Grobbelaar's shot of a whale, which took the top prize

The cultivation of wheat, barley and maize, which are easily stored and taxed, seems to have led to the emergence of large societies, rather than agriculture generally

Our brain wiring seems to undergo four major turning points at ages 9, 32, 66 and 83, which could influence our capacity to learn and our risk of certain conditions

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum cause and effect could bridge the gap

There are widespread concerns that deep-sea mining for metals will damage fragile ecosystems. But if mining ever goes ahead, hydrogen plasma could shrink the carbon footprint of smelting the metal ores

Analysis of the DNA and proteins of a range of animals has revealed that sperm’s molecular toolkit arose in our single-celled ancestors, perhaps more than a billion years ago

As the impact of global warming becomes more obvious, you might expect countries to step up climate action and preparation, but we’re seeing the opposite happen

From woolly mammoths to giant sloths, via some lesser-known ice-age beasts like 'killer koalas', the visuals in this documentary are simply astounding

The distant universe might be littered with supermassive stars between 1000 and 10,000 times the mass of the sun, which could solve a cosmic mystery about the origins of extremely large black holes

Spinning vortices of water trapped under the Thwaites glacier ice shelf account for 20 per cent of the ice melt. They’re expected to get worse as the world warms

Around 1000 markings on a slab of rock that was once a seafloor during the Cretaceous period may have been made by sea turtle flippers and swiftly buried by an earthquake

Conventional computing devices will play a crucial role in turning quantum computers into tools with real-world application

The discovery that a toxin made by bacteria found in dirty water might help trigger ulcerative colitis could lead to new treatments for this form of IBD

Astronauts strapped moss spores to the outside of the International Space Station for nine months - and most of them survived the challenging experience

Scientists have observed mice helping each other when they encounter difficulties during birth, prompting a rethink of caregiving among rodents and other animals 

Orforglipron, a GLP-1 drug taken as a pill, achieved positive results in people with obesity and type 2 diabetes, although it seems less effective than injectable drugs
