Amber heat-health alerts issued for most of England as temperatures could reach 36C or higher this week – latest updates
The upgraded alerts will be in place from 9am on Tuesday until 9pm on Friday
An 18-year-old died after getting into difficulty in the sea at Camber Sands beach, East Sussex, yesterday, bringing the number of deaths in open-water incidents over the hot, dry summer to over 40, according to estimates compiled by the Press Association.
The UK Health Security Agency (UKHSA) has updated heat-health alerts for nine regions in England, warning that rising temperatures this week may increase health risks, particularly for vulnerable groups.
It’s important that everyone is aware of the simple steps they can take to stay safe during periods of hot weather. Drinking plenty of water, avoiding the sun during the hottest part of the day and keeping indoor spaces cool are all things you can do to keep yourself and others safe.
For vulnerable groups including older adults and those with existing health conditions, warmer weather than result in serious health outcomes.

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.

Avoid rare species and only take what you need: how to forage and save money on your food shopping
While there are fears that people harvesting their food could put pressure on habitats, some ecologists suggest responsible foraging can boost conservation and biodiversity
Angus Morton crouches behind a cricket pavilion in a London park to snip stinging nettles from an unkempt patch of greenery.
“They’re so abundant and they’re so good,” says Morton, a regenerative gardener who pops out once a week to forage bits for dinner. “I use them in pesto, tea … I’ve even seen someone putting them in croquetas.”

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.

An ambitious new project in Florida is giving marine scientists hope: ‘I just see so much potential’
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 than Florida’s.
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 fire season of wildfire 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.

How clean air clubs are protecting Americans from wildfire smoke
Mutual aid groups that started giving out PPEs during Covid are now loaning air purifiers and distributing masks to fume-addled communities
Miquette Thompson’s home in rural Mendocino county has been covered in smoke all week. There are the nearby Feliz and Woodside fires in northern California, which have burned more than 1,000 acres, as well as the wildfires devastating Oregon and Washington that are sending smoke their way, too.
“It’s become not unusual,” she said of walking outside and seeing a hazy sky.

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.
