Our cells follow 24-hour circadian rhythms that regulate our blood sugar levels and are heavily influenced by light exposure. Scientists have harnessed this to show that just sitting by a window improves blood sugar control in people with type 2 diabetes

A distant world with carbon in its atmosphere and extraordinarily high temperatures is unlike any other planet we’ve seen, and it’s unclear how it could have formed

The largest study so far into the genetics of chronic fatigue syndrome, or myalgic encephalomyelitis, has implicated 259 genes – six times more than those identified just four months ago

Our understanding of the true nature of the cosmos relies on measurements of its expansion, but cosmologists have been arguing back and forth about it for more than 100 years

There are two small moons in orbit around Mars today, but both may be remnants of a much larger moon that had enough of a gravitational pull to drive tides in the Red Planet's lost lakes and seas

Controlling qubits with quantum superpositions allows them to dramatically violate a fundamental limit and encode information for about five times longer during quantum computations

Neisseria gonorrhoeae, the microbe responsible for gonorrhoea, is developing resistance to most antibiotics, which means we need new drugs to treat the condition. An antibiotic called zoliflodacin might be part of a solution
