Forecasting tool predicts when demand will be highest, allowing NHS trusts to better plan staffing and bed space

Hospitals in England are using artificial intelligence to help cut waiting times in emergency departments this winter.

The A&E forecasting tool predicts when demand will be highest, allowing trusts to better plan staffing and bed space. The prediction algorithm is trained on historical data including weather trends, school holidays, and rates of flu and Covid to determine how many people are likely to visit A&E.

Over the holiday period, the Guardian leader column is looking ahead at the themes of 2026. Today we look skyward, where a new lunar contest mirrors humanity’s struggle to live within planetary limits

During the cold war’s space race, the Apollo moon missions were driven by the need to prove American superiority. Having made that political and technological point with the 1969 moon landing, the contest between Moscow and Washington petered out. A new dash across the skies kicks off in 2026, reigniting geopolitical competition under the guise of “peaceful exploration”. The moon’s south pole is emerging as the most valuable real estate in the solar system, offering “peaks of eternal light” for solar arrays and ice deposits in craters shielded from the sun.

The US and a China-led bloc are eyeing the lunar surface and its potential to control a post-terrestrial economy. Space had been humanity’s last commons, supposedly shielded by the 1967 UN outer space treaty that bans state exploitation of the heavens. It is vague, however, on private claims – a loophole that is now fuelling a tycoon-led scramble for the stars. The aim is obvious: to act first, shape norms and dare others to object. Two lunar missions launching next year– Nasa’s Artemis II and China’s Chang’e 7 – are competing for strategic supremacy.
