Physicists found the shortest measurement to collapse a quantum state:


Measuring a quantum object makes it lose its odd quantum properties, and it only takes between 0.1 billionth of a second to 0.1 sextillionth of a second

Decarbonising the shipping industry will cost more than $1 trillion:


Powering all shipping vessels with zero-emission fuels by 2050 would slash the industry's emissions, but it would require between $1 trillion and $1.4 trillion of investment

Bubble of hot electrons seen hurtling around our galaxy’s black hole:


For about two hours, a bubble of extremely hot electrons whirled around the Milky Way’s supermassive black hole at 30 per cent of the speed of light, and then it was destroyed

Astronomers trace fireball in Earth's skies to space rock that made it:


In an effort to learn more about potentially hazardous asteroids, astronomers have used telescopic surveys to find an image of the space rock that produced a 0.4-kiloton fireball over the Pacific Ocean

Lemurs hug tree trunks to cool down when temperatures top 30°C:


A type of lemur called white sifakas embraces the base of some trees to release heat, with the base of the tree trunk being up to 5°C cooler than the surrounding air

Defining what constitutes a 'new' species isn't straightforward:


Even at this time of rapid extinction, there are many species to be discovered, but we need to take care over what we mean when referring to "new species", says Penny Sarchet
