New research reveals major drop in England’s air pollution
Air pollution in England has halved since 2003, according to new research from the Institute for Fiscal Studies (IFS). The study, funded by the Economic and Social Research Council, highlights significant progress in reducing PM2.5 levels — fine particulate matter known to damage health.
Interestingly, a sharp decline during the COVID-19 pandemic has resulted in lasting improvements, with pollution levels remaining much lower than pre-pandemic averages.
The findings reveal that ethnic minority communities have seen substantial benefits. The gap in exposure to PM2.5 between ethnic minorities and white populations narrowed from 13 per cent in 2003 to 6 per cent in 2023. This improvement stems from both demographic shifts and reduced pollution in urban centres like London and the Midlands, where many ethnic minority communities reside.

Despite these gains, 96 per cent of England’s population remains exposed to air pollution levels exceeding the World Health Organisation’s recommended limit, and experts stress the need for continued progress.
“New clean air zones in several of England’s largest cities and reduced steel production may have both played a role,” says Bobbie Upton, an IFS research economist. “It is important for the nation’s health, and for reducing health inequalities, that progress continues to be made on reducing air pollution.”

Astronomers edge closer to unlocking galaxy formation mystery
Astronomers from the University of Southampton have made significant strides in solving the “intergalactic mystery” of how the universe’s largest elliptical galaxies formed. These giant galaxies, often shaped like bulging footballs rather than the flat discs of galaxies like the Milky Way, have puzzled scientists for decades. New research suggests that cosmic collisions, where disc galaxies collided eight to 12 billion years ago, could hold the key.

Published in Nature, the study outlines how these galactic crashes drove massive amounts of gas to the centres of merging galaxies, triggering the formation of trillions of stars. Dr Annagrazia Puglisi, lead researcher, explained: “These cosmic collisions happened when the universe was in a much more active phase of its evolution. Our findings take us closer to solving a long-standing mystery in astronomy that will redefine our understanding of how galaxies were created in the early universe.”

Christmas magic on the rails: England’s ‘Train of Lights’ dazzles spectators
A steam train illuminated with festive lights recently turned heads in Paignton, a coastal town in southern England, offering a scene reminiscent of The Polar Express.
The annual Christmas Train of Lights, operated by the Dartmouth Steam Railway & River Boat Company, runs through the holiday season, enchanting passengers and onlookers alike with its vibrant display.
Local photographer Scott Williams captured breathtaking footage of the glowing train as it completed a trial run ahead of its official opening. He described the train as a “magical sight for anyone who sees it.”
