Even low levels of widely used agricultural chemicals were linked to accelerated ageing, research suggests

The lifespan of fish appears to be drastically reduced by pesticides, a study has found.

Even low levels of common agricultural pesticides can stunt the long-term lifespan of fish, according to research led by Jason Rohr, a biologist at the University of Notre Dame in Indiana.

Pressure mounting for use of glyphosate, listed by WHO since 2015 as probable carcinogen, to be heavily restricted

Children are potentially being exposed to the controversial weedkiller glyphosate at playgrounds across the UK, campaigners have said after testing playgrounds in London and the home counties.

The World Health Organization has listed glyphosate as a probable human carcinogen since 2015. However, campaigners say local authorities in the UK are still using thousands of litres of glyphosate-based herbicides in public green spaces.

There was a time when nobody picked up after their dogs – and it would have been considered disgusting to do so. What caused the change in attitude?

A PE teacher from Cardiff called Tony is frozen solid after being caught in an avalanche in 1979. There he remains until global heating sees to his thawing and he pops up in the present day, exactly as he was back then. Comedy ensues. This is make-believe, by the way; it’s the premise of Mike Bubbins’ BBC series Mammoth. In the masterful opening scenes, to the sound of Gerry Rafferty’s Get It Right Next Time, we see Tony being scornful, angry, frightened and disgusted by four things that didn’t happen before his big freeze.

He scoffs at a bloke carrying a baby in a sling, gives a charity chugger very short shrift, and jumps out of his skin when a youth on a hoverboard zips past him. But it was Tony’s disgust at a woman picking up her German shepherd’s poo that got me thinking. When did picking up dog poo become the thing to do? Or, put another way, when did just leaving it there become the thing not to do? When did we start becoming disgusted at those who didn’t pick it up rather than those who did? This is a pretty seismic cultural shift, I’m sure you’ll agree.

Study from research firm finds that US greenhouse gas emissions grew faster than economic activity last year

In a reversal from previous years’ pollution reductions, the United States spewed 2.4% more heat-trapping gases from the burning of fossil fuels in 2025 than in the year before, researchers calculated in a study released on Tuesday.

The increase in greenhouse gas emissions is attributable to a combination of a cool winter, the explosive growth of datacenters and cryptocurrency mining, and higher natural gas prices, according to the Rhodium Group, an independent research firm. Environmental policy rollbacks by Donald Trump’s administration were not significant factors in the increase because they were only put in place this year, the study authors said. Heat-trapping gases from the burning of coal, oil and natural gas are the major cause of worsening global warming, scientists say.

Exclusive: Some scientists say many detections are most likely error, with one high-profile study called a ‘joke’

High-profile studies reporting the presence of microplastics throughout the human body have been thrown into doubt by scientists who say the discoveries are probably the result of contamination and false positives. One chemist called the concerns “a bombshell”.

Studies claiming to have revealed micro and nanoplastics in the brain, testes, placentas, arteries and elsewhere were reported by media across the world, including the Guardian. There is no doubt that plastic pollution of the natural world is ubiquitous, and present in the food and drink we consume and the air we breathe. But the health damage potentially caused by microplastics and the chemicals they contain is unclear, and an explosion of research has taken off in this area in recent years.
