An exclusive New Scientist survey of leading scientists reveals widespread concern that schemes to tweak Earth’s atmosphere could launch within decades in a risky bid to cool the planet

Confining and rotating extremely cold atoms or molecules within atomic “Ferris wheels” made from laser light could test relativity’s predictions on the quantum scale

We have more satellites than ever before, but when they burn up they create a new kind of air pollution. Evidence is now revealing what effects this could have and how to tackle it

The comet-like object Chiron has been caught in the process of forming new rings, which could help us understand how these complex systems work

Many of the signs of perimenopause can also be symptoms of other conditions, and some of these get increasingly dangerous if they’re misdiagnosed

It has remained mysterious for millennia, but we’re finally uncovering the profound role the lymphatic system plays in everything from preventing dementia to fighting cancer

Age-related macular degeneration is a common cause of vision loss, with existing treatments only able to slow its progression. But now an implant in the back of the eye and a pair of high-tech glasses have enabled people with the condition to read again

Turning the crank on a simple device filled with nanoparticles can remove serious pathogens from water in seconds, making it suitable for areas without electricity

When Homo sapiens and Neanderthals interbred, a genetic variation affecting red blood cells may have hindered reproduction in women who were hybrids, and this might have played a part in Neanderthals’ demise

An analysis of patient records suggests that mRNA covid-19 vaccines boost the immune response to cancerous tumours when given soon after people start a type of immunotherapy, extending their lives

Quantum computers hold great potential for solving many problems more quickly or efficiently than conventional computers, but researchers are starting to identify where they could falter

One of the longest trials of artificial sweeteners to date found that they may increase beneficial gut bacteria, though the boost may also be related to weight loss

Physicists have tried so many different ways to find dark matter, but none has been successful. Now an unexpected contender has entered the arena - ordinary table sugar.

Experiencing severe hardship in childhood can have a lasting impact. Understanding this better could open the door to more effective treatments

A new chip design includes 41 vertical layers of semiconductor and insulator materials, which allow it to outrun the limits of miniaturisation

A mysterious excess of gamma rays in the middle of the Milky Way may come from dark matter particles smashing into one another and annihilating

If users chose the most efficient model each time they performed a task with AI, researchers calculate it would slash energy consumption by more than a quarter

The rush to grow more biofuels continues, despite the fact they increase CO2 emissions rather than lower them, raise food prices and devastate nature. It has to stop, says Michael Le Page

The evidence to support phone bans in schools has been inconclusive, and now it seems that the move could harm some students' mental health in a particular way
