Hearing a sound while working on a complex puzzle, and then hearing it again during sleep, helped lucid dreamers better tackle the problem the next day

A mathematical equivalent of a microscope with variable resolution has shed light on why some atoms are exceptionally stable, a riddle that has persisted in nuclear physics for decades

The psychedelic DMT has been linked to improved mental health outcomes before, but now, scientists have shown it reduces depression symptoms more than a placebo when given alongside therapeutic support

The big bang wasn’t the start of everything, but it has been impossible to see what came before. Now a new kind of cosmology is lifting the veil on the beginning of time

Biologists have debated the reason why Homo sapiens evolved a prominent lower jaw, but this unique feature may actually be a by-product of other traits shaped by natural selection

We are used to heat flowing from hot objects to cool ones, and never the other way round, but now researchers have found it is possible to pull off this trick in the strange realm of quantum mechanics

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark energy. Columnist Leah Crane explores what observations tell us about how much universe is out there and whether it’s shaped like a sheet, a saddle or something else entirely

Intermittent fasting appears to be no better than doing nothing when it comes to helping people who are overweight or have obesity lose weight

Five dietary patterns that involve eating lots of plants have been linked with living up to three years longer, even among people who are genetically predisposed to have a shorter life

Finding rhinoviruses, which cause the common cold, in preserved medical specimens and analysing their RNA genome could let us trace the evolution of human illness

Simulations suggest that two enormous masses of hot rock have been involved in generating Earth’s magnetic field and giving it an irregular shape

Scientists may have stumbled across a network of vessels in the brain that helps clear out waste fluid – a discovery that could "represent a paradigm shift in our understanding of all neurodegenerative diseases"

Immune cells in the brain that go rogue contribute to the death of neurons, so getting rid of them may slow the progression of neurodegenerative conditions like amyotrophic lateral sclerosis

A growing body of psychological research shows that the best relationships – romantic or otherwise – come with a feeling of personal growth. Columnist David Robson explores the evidence-backed ways to broaden our horizons and connect more deeply with our loves, our friends and ourselves

Life may have begun when RNA molecules began to replicate themselves, and now we’ve finally found an RNA molecule that is very close to being able to do this

The planets around a nearby star seem to be in the wrong order, hinting that they formed through a different mechanism than the familiar one by which most systems grow

The activity of certain neurons may influence our endurance for exercise, and these could be targeted to help us run faster for longer

The idea of self-amplifying gene editing is to get cells to pass on packages of CRISPR machinery to their neighbours, boosting the effect

A fleet of wind-propelled robot boats could act as a sensor network covering a wide area and relay acoustic signals to a submarine

Many researchers thought that earthquakes in the Himalayas recur at regular intervals – but an analysis of sediment cores has shown they are largely random, and the region has seen far more than we previously realised
