London Tree Ring project aims to create corridors of plant and animal life around the city to strengthen its biodiversity
Harry Ewing is heaping branches and foliage from the forest floor on to a dead hedge, reinforcing the protective circle around his newly planted trees in Hadley Wood, north London. He is in a glade created by a fallen oak that was previously overrun with thick bramble.
“I feel very happy – the trees are growing already. It’s really nice seeing it when it starts,” says Ewing.

Scientists are returning to a wartime solution that may be more sustainable than the traditional rubber tree
There is a global shortage of natural rubber and dandelions may be coming to the rescue. In the second world war there was such a severe shortage of rubber that the Allies used the Russian dandelion, Taraxacum koksaghyz, from Kazakhstan. Soviet scientists found the dandelion roots produced enough white milky latex to make natural rubber, but when the war ended producers returned to the traditional rubber tree, Hevea brasiliensis.
But the demand for rubber is now increasing, with rubber trees suffering from a fungal disease and the impacts of extreme weather caused by the climate crisis. So, scientists are looking again at using dandelions, with the added benefit that they grow in temperate climates, are a sustainable crop that do not need pesticides and lots of water, and don’t lead to the deforestation common in tropical rubber tree plantations.

Frome, Somerset: This much-maligned midsummer menace has few friends among humans, but look closely and you might find an orgy of eating and mating
Eyes smarting, throat tickling, nostrils dog-wet, I pick my way along a thready footpath up the combe, only half-prepared for the next irritation. Nettles, I am watching you. But not well enough it seems, for a sneaky one hidden under the skirts of encroaching grasses and umbellifers grazes the back of my bare calf. It induces that tingling somewhere between pain and pleasure – one that quickly develops into a needling throb.
It is hard to love a nettle. This much-loathed plant may be one of the first that many children learn to identify, for their own protection. It has a secondhand look, with wrinkly, crinkly jagged hearts for leaves. It has no sheen; it does not shine. Near-invisible fine hairs on the upper surfaces give the dulled green a dusty, soiled appearance.

Sea ice is melting fast, worsening the climate crisis, but a bold attempt to rethicken it is showing early signs of success
‘This would have been a wild dream a year ago,” says Andrea Ceccolini, standing on Arctic sea ice just a 4-mile snowmobile ride from the Inuit town of Cambridge Bay, northern Canada. To his left are sky blue ponds of meltwater created in the last few days by a sun that no longer sets in the high north summer. To his right, the sea ice is still a brilliant white, the light dusting of snow on top continuing to sparkle.
“It’s incredibly different, the boundary – I mean, you can point to it,” he says. The difference is the result of a bold geoengineering experiment being conducted by Ceccolini’s company, Real Ice, funded by the UK government.

Almost every child, including those from high-income countries, is now exposed to at least one hazard
Half of the world’s children are exposed to at least three overlapping climate hazards threatening their health, education and survival, according to a Unicef report.
Globally, children face increasing threats from heatwaves, storms, floods and droughts as the climate crisis worsens, with more than one billion facing at least three of these at once.

Tech is helping to identify and save new specimens and could open ‘genomic goldmine’ of fungi data
The rise of AI and digitisation could be a turning point in the “race against extinction” faced by botanists trying to identify and save vital plants before they vanish, according to a major report from Royal Botanic Gardens, Kew.
New technology is enabling scientists to track how flowering times have shifted by weeks around the world, rapidly identify new specimens and even get crucial genetic data from 180-year-old fungus specimens, potentially opening a “genomic goldmine”. Digitisation and online access to millions of specimens that were until now only accessible in archives is also producing new insights, especially in the global south.

The short-tailed roundleaf bat was feared extinct until scientist Iroro Tanshi found one in Afi sanctuary in Nigeria, and set out to protect the only confirmed roosting colony
Just after sunrise, a cacophony of whoops and chatter can be heard over the verdant forests of the Afi mountain wildlife sanctuary. Nestled within the Cross River rainforest in south-east Nigeria, and spanning an area about the size of central Paris, the steep sanctuary is a haven for endangered gorillas, drill monkeys, the grey-necked rockfowl – and the short-tailed roundleaf bat.
The Nigerian biologist Iroro Tanshi remembers the moment she first spotted the endangered bat in 2016, during a field expedition for her PhD research. “We were trapping near a roost that night, so we caught a lot of bats,” says Tanshi. But, she adds: “This looked very, very different. Big-eared.” She promptly turned to her identification guide, which revealed that the tiny furry creature she was holding between her fingers was Hipposideros curtus, better known as the short-tailed roundleaf bat, last recorded in the wild in the 1970s.

Residents of West Oakland, which suffers from toxic waste and high pollution rates, rally against a coal export facility
West Oakland, a California neighborhood known for its rich history of Black activism from the Pullman Porters’ union to the Black Panthers, might not seem like the site of the country’s next great coal project.
But that’s exactly what the Trump administration is pushing for – with the injection of $75m to build a sprawling coal export terminal in the nearby port of Oakland.

‘Saddened, stunned, surprised and haunted’ is how one surfer describes the mood at the popular Sydney beach two days after Leah Stewart was bitten by a great white
Under a clear blue sky on a Monday morning, Coogee beach in Sydney’s east is quiet.
A few swimmers have ventured into the ocean pools at the northern and southern ends of the beach. Most others sit on the sand, looking towards the water.

Amid fears the wreck will be more accessible to explorers – and new species – as the climate warms, conservationists want to create the region’s first underwater protected area
The harsh temperatures, treacherous currents and shifting pack ice of the Antarctic’s Weddell Sea, which crushed and sank his ship, Endurance, in 1915, led Ernest Shackleton to describe it as the “worst portion of the worst sea in the world”.
For more than a century, the inhospitable conditions, which present a challenge even for modern icebreaker ships, helped to protect the lost wreck, which was discovered in 2022, its structure still largely intact.
