Efforts are underway to tidy up the ocean's biggest plastic hotspot. But this cleanup operation could be damaging a unique ecosystem and doing little to stop the overwhelming plastic problem | Continue reading
Several enormous craters left by explosions have been spotted in Siberia over the past 15 years, and a new explanation links them to hot gas – and climate change | Continue reading
Invasive mink, which are native to North America, have been eradicated from most of East Anglia in England after a trial used the scent of the animals' anal glands to lure them into traps | Continue reading
Titan’s methane seas have ephemeral “magic islands” that have baffled scientists for years. They may be made of odd, porous clumps of snow | Continue reading

Brain scans of 110 first-time mothers during and after pregnancy showed that some brain regions become thinner during pregnancy and that giving birth largely reverses this effect | Continue reading
NASA is hoping to gather evidence that its X-59 aircraft will be able to fly at the speed of sound quietly, justifying a change in the regulations to allow supersonic commercial aviation | Continue reading
A secure exchange between a merchant and a buyer has been successfully tested as a proof of concept using a small quantum computing network in China | Continue reading

A model of US water systems foresees a big drop in hydropower generation by 2050 as the climate gets drier and river flow decreases, while electricity demand is set to increase | Continue reading
When we exhale, we reveal distinctive information about the shape of our airways, which could serve as an ID test for unlocking smartphones – and unlike some other biometric ID tests, this one can’t be hacked after we die | Continue reading
Black holes may be hiding within stars and their extra mass could help explain odd gravitational effects in the universe ascribed to dark matter | Continue reading
