Physical and psychological impacts of a tap water parasite outbreak continue to be felt in south Devon

• South West Water fined £1.85m over parasite outbreak in Devon

Most of the tourists milling around the busy fishing harbour or visiting Agatha Christie’s riverside holiday retreat have probably forgotten what South West Water euphemistically calls the “Brixham incident”.

But for residents at the centre of the “incident” – a parasite outbreak that caused perhaps hundreds of people in south Devon to fall ill after they drank contaminated water – the physical and psychological impacts are still keenly felt.

Pauline Hanson wants the government to take a stake in resource operations. While experts say this may sound reasonable, the devil’s in the details

In September 2022, Pauline Hanson stood up in the Senate to berate the chamber – but she wasn’t fired up about immigration or the latest battle in the never ending culture wars.

The One Nation leader was arguing for gas and oil exploration laws to change “to make the benefit of the Australian community a guiding principle in the interpretation of the act”.

Investigation reveals regulator let firms off the hook on cleanup bonds despite backlog that will take decades to clear

When Christiaan van Woudenberg moved to Erie, Colorado, in 2007, he never imagined he would become an anti-fracking activist. He simply thought he was buying his dream home – a four-bedroom with a panoramic mountain view, 30 minutes north of downtown Denver.

Then, in 2014, the drilling started. Oil and gas rigs sprang up, some just 800ft (240m) from his bedroom window. The dream turned to nightmare: loud noises rumbled all night long, and the air stank like exhaust. Neighbors started getting headaches and nosebleeds, and Van Woudenberg developed new respiratory issues. He kept his windows shut and worried about his daughters going outside.

Novel forms of CO₂ removal must expand at ‘highly ambitious rates’ if world is to limit global heating to 1.5C, says study

Humanity must suck carbon out of the atmosphere with new technologies even faster than the breakneck speed with which it has deployed solar panels if it is to limit global heating to 1.5C, a report has found.

Novel forms of carbon dioxide removal (CDR) must grow at “highly ambitious rates” to bridge the gap between what governments have pledged to clean up and what is needed to comply with the Paris climate agreement, according to researchers. They said the next five years were critical to establishing the technologies’ role in limiting climate damages.

Kielder in Northumberland is balancing commercial production with conserving peatland and rare plants and animals

Driving through part of Northumberland, you might look around at the tall Sitka spruce and imagine yourself in Canada’s evergreen forests, or perhaps, on a sunny day, in northern California. Instead, you are in England’s largest forest, Kielder, often heralded as a success story that balances commercial production with ambitious conservation.

The first trees of this 60,000-hectare forest were planted 100 years ago with one aim: increasing Britain’s timber reserves. Much has changed since then. From a single-use plantation, Kielder Forest has been transformed into a haven for nature and an invaluable environmental asset.

Scientists believe they may now have found the cause of Fair Isle’s pollution – and warn that it should be ringing alarm bells in other coastal areas

When the wind picks up on Fair Isle, Britain’s most remote inhabited island, puffs of seafoam start to drift across fields like tumbleweed. The pale yellow blobs are ubiquitous enough to hold their own place in the island’s mythology: known as the butter churned by a local troll, Lukki Minni.

“When the Atlantic gets going, foam covers the whole island,” says Tommy Hyndman, an artist who moved to the Fair Isle from upstate New York two decades ago. “Your windows get caked and your plants all die from the salt.”

UN agency predicts phenomenon that supercharges weather extremes has 80% chance of forming before September

The world must prepare for the imminent return of El Niño and the supercharged weather extremes it brings, the UN has warned.

The powerful natural weather pattern, which raises global temperatures and worsens some rainfall, has an 80% chance of forming before September and a 90% chance before November, the World Meteorological Organization (WMO) said on Tuesday.

Hogshaw, Derbyshire: We’re up to 27 spotted orchids in our garden, and every one is a miracle

When we moved to this house, we didn’t need the encouragement of No Mow May – the ecological campaign advocating restraint in the garden. Our old lawnmower was designed to tackle your average handkerchief and leaving nine-tenths of the new place uncut was a matter of necessity as much as self-control.

The highlight of last year’s non-labouring efforts addressed directly the whole meaning of no-mow gardening. Who knows what lies hidden in a uniform shorn expanse, unless it is allowed to express itself? A slender pink flower among the green swathe turned out to be a spotted orchid, the commonest, most widespread of our 54 UK species. With this as a search image, I eventually climbed to 16 spikes last year. That alone felt like a triumph.

Looking down the barrel of a telephoto lens, Dr Elizabeth Hawkins tells the dolphins circling the research boat to work it for the camera.

Net zero industry accounts for more than a million jobs and benefits whole country, according to CBI Economics

More than a million jobs, higher wages, nearly half a trillion pounds in investment in the pipeline – the UK’s green economy is powering ahead, according to research by the country’s leading business organisation.

The net zero economy, which is worth more than £100bn a year, benefits all of the UK, according to the CBI Economics analysis commissioned by the Energy and Climate Intelligence Unit thinktank, despite critics who want to abolish the UK’s net zero targets.

While Westminster’s attention is focused on Andy Burnham and Makerfield, another pivotal byelection is taking place in Scotland’s north-east

The coming byelection in Makerfield, from where Andy Burnham aspires to make rapid progress towards Downing Street, is perhaps the most consequential in British political history. But the decision by the Scottish National party’s former Westminster leader, Stephen Flynn, to relocate to Holyrood means that another pivotal contest is taking place more than 350 miles to the north. If Makerfield is a test case for Mr Burnham and Labour’s ability to see off Reform UK, Mr Flynn’s old constituency of Aberdeen South is on the frontline of the increasingly fraught politics of North Sea oil.

Labour, despite finishing second in the 2024 general election thanks largely to anti-Tory tactical voting, will not be expecting much this time round. The ramifications of Donald Trump’s reckless war in Iran have exposed Britain’s ongoing vulnerability to fossil-fuel-related energy shocks, highlighting the practical benefits of moving to a green economy. But the knock-on effects of the closure of the strait of Hormuz have also been a gift for the Scottish Conservatives and Reform, who are framing the byelection as a local referendum on reviving oil and gas production beyond Westminster-imposed limits.

The 15-week-old triplets get their first swimming lesson from their mum, Bonita, and dad, Manu. The two boys, Uca and Yali, are named after an area of the Amazon rainforest and the second largest region in Peru. The female pup is named Yara, which means ‘river spirit’ in Brazilian folklore. Endangered giant otters face an uncertain future as conservationists estimate that only a few thousand remain across South America. The pups have been born as part of the international conservation breeding programme in European zoos that is working to safeguard them from extinction

It is a short-term fix, but AC is an essential tool for many for whom the heat can be harmful, and even life-threatening

I used to love a heatwave. I was the sort of British person who acted like I was in the Mediterranean if the sun was slightly visible, coercing friends to take the outside restaurant table and eagerly working in the garden until my MacBook started to overheat rather than my internal organs. That was until I developed post-viral fatigue from the flu nine years ago.

Now, the heat means suffering rather than pleasure: less energy, more pain and worse breathing. This has only increased as heatwaves across Europe have soared. I have spent this week of record-high May temperatures in the UK largely in bed, with the blinds drawn and two 5ft-high fans looming over me like security guards at a club no one wants to get into.

Clean power remains essential. But until it arrives, Britain must stop LNG made scarce by the Iran war setting gas and electricity prices

The US-Israel war on Iran will drive household energy costs in Britain to their highest level in two years over the summer. This has given fresh impetus to calls for the energy secretary, Ed Miliband, to change course. The cabinet minister is vulnerable because he promised cheaper bills if Britain embraced his clean, green power plan.

Critics, including Labour’s former prime minister Sir Tony Blair, are circling. Yet Mr Miliband ought to ignore the naysayers. Until global carbon emissions, including Britain’s, are reduced to net zero, the planet will continue to fry and temperature records will continue to be broken.

For those of us working in Aboriginal health, the outbreak doesn’t come as a surprise. We must invest in housing that keeps remote communities safe

The diphtheria outbreak should shock Australia. Not simply because a disease once considered virtually eradicated has returned, but because of where it is spreading and why.

More than 220 cases have been recorded in 2026, primarily across the Northern Territory and northern Australia. The overwhelming majority of patients are Aboriginal people, including those living in remote and very remote communities.

Investigators are still searching for what caused the recent deaths of a mother and her calf, but conservationists say the animal’s shrinking habitat may be the first place to look

The two elephants were found dead in the Indonesian province of Bengkulu, in an area of “production forest” in southern Sumatra. The mother and her calf were lying side by side with their tusks still intact.

Unlikely to be poachers, the cause of their deaths – and that of a tiger nearby – at the end of April is still being investigated but conservationists say this is not an isolated case. It is estimated that seven wild elephants have died in Bengkulu since 2018.

Calaminarian grassland is a rare habitat where plants thrive in soils contaminated by heavy metals. But should these toxic meadows be protected or allowed to fade away?

At first, the small purple flowers are hard to spot in the weak May sunshine. Slowly the drifts of delicate mountain pansies, along with the white rosettes of alpine pennycress, begin to jump out, scattered across an area little bigger than a football pitch, on the banks of the River Allen in Northumberland.

This is a pocket of calaminarian grassland, an increasingly rare habitat where specialist plants called metallophytes have adapted to live in soils deeply contaminated by heavy metals, the legacy of more than 1,000 years of lead mining.

The Lincolnshire seaside town is often written off by YouTubers as a place defined by deprivation and decline. But for many young people it's a place they love and are proud to call home, even though high unemployment limits their opportunities. The Guardian follows 19-year old Cohen, who is desperate to find a permanent job while running a mascot hire company and chasing his dream of becoming a professional wrestler

• This video is part of a year-long project, Against the tide, from the Guardian’s Seascape series, reporting on the lives of young people in coastal communities across England and Wales

High unemployment and a lack of support mean life can be tough in Grimsby, but 19-year-old Cohen is determined to make the best of life in this coastal town

It’s mid-afternoon in the Lincolnshire seaside town of Cleethorpes and Cohen is sitting in the back seat of a car putting on an Easter bunny outfit. A group of teenagers nearby stare in amusement. Cohen isn’t fazed. He is hoping we can take some new photographs that he can use to advertise his mascot business for the upcoming holidays.

Cohen, 19, lives with his parents a couple of miles down the road in neighbouring Grimsby and set up Co Co Mascots last year as one of his many attempts to find work. People can hire him in one of the outfits for birthday parties, events and doorstep surprises for children. He’s done a few paid gigs so far, which has been a boost for his confidence, he says, but what he really wants is a permanent job.

Staff at the Mount Kenya Wildlife Conservancy are helping the repatriation of ‘the shiest antelope’ from western zoos to their native east African country

“We are bringing the boys home,” says Ngenoh Erick Kibet, a wildlife officer at the Mount Kenya Wildlife Conservancy, as he hears of the moment that a cargo plane carrying four mountain bongo has touched down on a wet runway at Jomo Kenyatta international airport.

The operation is the culmination of two weeks spent in Czechia, a first flight for Kibet, and a decades-long collective effort to rescue a species on the edge of extinction.

The 100th bongo calf was recently born at the conservancy

A new exhibition, Jurassic Oceans, showcases the fearsome creatures that lurked below the surface – and offers a stark warning about the impact of warming waters on marine ecosystems today

Deep in the bowels of the Natural History Museum, Kate Whittington is standing in front of the skeleton of a 23ft plesiosaur, one of prehistoric Earth’s most fearsome marine reptiles, explaining how it would eat us for dinner, were it still around today.

“Its long neck allowed its head to get a head start on its body,” says the museum’s exhibition and interpretation manager. “So it could sneak up on prey and grab it [with its mouth] before its body and flippers created a disturbance in the water.”

‘Floral buzzing’, the vibrations bees use to shake pollen loose from flowers, takes more energy than previously thought

Bees use as much energy collecting pollen through “floral buzzing” as they do taking off in flight, a study shows.

Scientists have found the vibrations bumblebees use to shake pollen loose from flowers are among the most exhausting behaviours they perform, forcing bees to “carefully choose” which flowers are worth visiting.

Study of Channel finds levels of toxic Pfas in Solent at 13 times safe limits in some places, with much coming from treated sewage

Scientists have found high levels of toxic Pfas, or “forever chemicals”, in soil, water and throughout the marine food chain in the UK’s Solent strait, including at protected environmental sites, according to a new study.

In some samples, pollution was 13 times the safe threshold for coastal waters. Others, which were below legal limits for individual chemicals, failed tests for combined toxicity.
