‘It’s very challenging’: how the Duke of Westminster’s farm is taking on the climate crisis
Amid world pressure from heatwaves and fertiliser shortages, billionaire’s business has invested in circular farming and biomethane
There is a distinctive smell of cow manure in the air at the Duke of Westminster’s dairy farm near Chester. It is a world away from the collection of grand West End properties controlled by the duke that form the backbone of his near £10bn fortune, a decade on from becoming Britain’s youngest billionaire.
As part of his 349-year-old Grosvenor empire, Lea Manor Farm on the duke’s Eaton Estate in north-west England has fared better than most dairy farms in recent years.

People flocking to Spain to view solar eclipse could spark more ‘devastating’ wildfires
Northern Spain will be one of the best places in world to view phenomenon with 460,000 extra visitors expected
Authorities in Spain have warned of an increased risk of fires when hundreds of thousands of people head to the hills and beaches to get a better view of Wednesday’s total solar eclipse.
“The vegetation is extraordinarily dry and the smallest spark or carelessness could lead to devastating forest fires,” the environment minister, Sara Aagesen, said on a visit to Niebla in the south of the country, the site of Spain’s latest fire.

Harry Potter fans force relocation of £430m undersea cable to avoid Dobby’s ‘grave’
Power cable linking UK and Ireland now passes near Bronze Age human burial remains instead of fictional grave on Welsh beach
Harry Potter fans have forced a new multimillion-pound power cable between the UK and Ireland to be relocated after complaining it would desecrate the “grave” of Dobby, a fictional elf.
The character was laid to rest on Freshwater West beach in Pembrokeshire, Wales, in the film Harry Potter and the Deathly Hallows. Fans of the wizard series come to leave stones reading “Here Lies Dobby” despite being asked not to by the land owner, the National Trust, because the beach is an ecologically sensitive site.

Typhoon Dolphin: more than a million people evacuated in China as record rainfall dumped on Shanghai
Authorities warn that days of intense rain could trigger widespread flooding and landslides as storm moves north and further inland
More than a million people were moved to safety across eastern China by Sunday evening as powerful Typhoon Dolphin made landfall amid fears torrential rain would cause flooding and landslides.
Wenzhou, a coastal city in Zhejiang province, said it relocated more than 900,000 people and opened more than 1,500 emergency shelters. In neighbouring Fujian, 98,900 people were moved from high-risk areas.

Country diary: The thin, hungry fox goes for the sleepy hen | Nic Wilson
Hitchin, Hertfordshire: A rare daytime attack on our chickens led to a standoff. But I could see this animal was suffering in the heatwave
High-pitched shrieking shattered the mid-morning calm and I knew, immediately, that there was a killer on the loose. I tore out of the patio door and across the lawn to intervene between predator and prey, facing down a fox with black tail feathers in its jaws. Shouting and growling, all animal myself, I was driven by instinct to protect our chickens, Cumulus and Burnet, from further onslaught.
The fox froze. Stared. I stared back. An unfathomable silence. Breaking the stalemate, I glanced over my shoulder, but my girls had evaporated. Moss (our third hen) is broody and spends much of her time on the nest, so I sidled over to the chicken run while still watching the fox, and there she was. Fluffsome, flat and completely unharmed.

Jean hoped bird flu wouldn’t come to Australia. Then it arrived – and she saw a tern ‘trembling and swaying’
Volunteers are on the lookout for sick birds as outbreak shatters ‘fairytale belief’ that disease would not reach Australia

Bird enthusiast Jean Turner hoped avian flu would never arrive at her doorstep.
At her home on Kangaroo Island in South Australia, bossy fairy wrens chirp at her from the deck, grey currawongs clumsily fall into her bird bath, and fluffy, hooded plover chicks emerge from speckled eggs in front of her binoculars.

Can Florida’s ‘coastal corridor’ project safeguard wildlife and boost economy?
Conservationists have created a ‘coastal corridor’ of ocean-based projects designed to preserve and nourish vulnerable marine life
From disappearing manatees to bleached coral reefs, gender-changing turtles and oyster beds destroyed by hurricanes, no other state’s marine life faces the magnitude of climate-related challenges that Florida’s does.
Now, wildlife authorities are attempting to bring some cohesion to tackling the diverse slate of issues by borrowing from a playbook that has already proved successful on land.

‘Unprecedented, dangerous territory’: US north-west reckons with a summer of historic wildfires
Extreme conditions in Washington and Oregon have fueled fast-moving fires, leaving the region draped in toxic plumes – and the danger isn’t over
Piles of twisted metal and ashen debris line the cul-de-sacs where the tranquil suburbs of Spokane, Washington, once stood.
The scale of devastation from a historic wildfire season in the Pacific north-west has come into sharper focus as firefighters wrangle a trio of blazes that consumed at least 846 structures on the eastern side of the state.

Otkrivena nova genetska ranjivost akutne mijeloične leukemije
Studija objavljena u časopisu Nature Cell Biology izvještava o novoj ranjivosti akutne mijeloične leukemije (AML) koja bi mogla dovesti do novih terapija za liječenje ovog raka uz minimiziranje štete za normalne stanice. Inače, znanstvenici s Medicinskog fakulteta Baylor i suradničkih institucija proučavali su u ovoj studiji novi način na koji djeluju lijekovi koji neutraliziraju mutacije enzima FLT3.

Skriveni mikrobi unutar tumora mijenjaju imunitet i liječenje raka
Sve veći broj dokaza mijenja način na koji se rak shvaća, stavljajući pozornost na intratumoralnu mikrobiotu kao snažne, ali prethodno zanemarene igrače unutar mikrookruženja tumora. Daleko od toga da su sterilni, tumori su domaćini složenim zajednicama bakterija, gljivica i virusa koji aktivno utječu na napredovanje bolesti, imunološke odgovore i ishode liječenja.

Novi tretman za bolesti desni ubija štetne bakterije, a istovremeno čuva korisne mikrobe
Znanstvenici sa Sveučilišta Nagoya u Japanu stvorili su inovativan tretman za parodontitis koji cilja i uklanja štetne bakterije, a istovremeno čuva korisne oralne mikrobe bitne za zdravlje. Oralno zdravlje ovisi o raznolikoj i uravnoteženoj mikrobnoj zajednici. Porphyromonas gingivalis (P. gingivalis) je ključni patogen koji izaziva upalu i remeti tu ravnotežu. Takav poremećaj može oštetiti kost koja podupire zube i na kraju dovesti do gubitka zuba.
