Fibromyalgia, which causes chronic pain all over the body, is poorly understood, but two studies – made up of millions of participants – are helping us get to the roots of the condition

A four-fingered robotic hand built from Lego Mindstorms pieces can push, pull and grip with almost as much force as a leading 3D-printed hand

Birds all over the world break into a dawn chorus every morning – now experiments in zebra finches suggest both a mechanistic and a functional explanation for this phenomenon

A growing body of research suggests testosterone replacement therapy can alleviate menopausal symptoms such as a decrease in libido, mood swings and brain fog. But some in the field are sceptical

Scientists are finding out how coffee beans are transformed when they pass through the guts of Asian palm civets in the hope of replicating the process without using animals

Buried underground near the surface, frozen regions of Mars could have tiny hidden channels full of liquid water, which could be a habitable environment for microscopic organisms

Microbes high in Earth’s stratosphere produce pigments to protect them from UV light – so similar molecules could be biosignatures of life elsewhere in the galaxy

Solar electricity is growing rapidly, but can it really dominate the global energy system? Here is what it will take for us to power the planet on sunshine

Human embryos formed with in vitro fertilisation can develop genetic abnormalities in the time between genetic testing and implantation – though this may not affect their viability

Lithium-ion batteries are prone to catching fire when damaged, but a simple change of electrolyte material can put a stop to the vicious chemical cycle that causes the problem

So far, immune cells that have been engineered to kill cancers, known as CAR T-cells, haven’t worked well against solid cancers - but a study in mice suggests that could soon change

Studies have suggested that Wegovy directly boosts heart health, beyond just the benefits of losing weight, and now that has been demonstrated in a robust trial in people

The White House Effect is a distressing look back at how President George H. W. Bush came to abandon his climate ambitions. It is essential viewing and a glimpse at a world that could have been, says Bethan Ackerley

Future Chronicles is our regular speculative look at inventions yet to come. In this latest installment, we journey to 2050, when technology had been developed so that criminals could be monitored at home. It led to a drop in crime, writes Rowan Hooper

The books, TV, games and more that New Scientist staff have enjoyed this week

In the run-up to this year's COP in Brazil, Madeleine Cuff explores The Climate Diplomat, a poignant account by the late Peter Betts, a negotiator who showed what diplomacy can achieve

Skin irritation, such as through eczema, promotes hair growth in mice, which prompted scientists to create a treatment that works via similar pathways, with no discomfort required

There are hundreds of coherent theories attempting to explain the origins of experience. Robert Lawrence Kuhn explores what they reveal about free will, artificial intelligence and life after death

A new quantum computing protocol may be able to augment a standard technique for understanding molecules in chemistry, biomedicine and materials science

Classical swine fever reduces productivity and harms animal welfare, but pigs have now been genetically edited to make them completely resistant to the disease
