Prof Gustaf Hugelius warns wildfires could accelerate release of methane and carbon as vast regions approach irreversible thresholds
Heatwaves and wildfires are not just scorching forests, they are adding to the tipping point risks in the world’s vast permafrost regions, which contain three times more carbon than all the living vegetation on Earth.
This is a major concern for Gustaf Hugelius, a professor at the Bolin Centre of Climate Research at Stockholm University, Sweden, and a leading authority on the risks from thawing tundra and peatlands. In this Q&A, he explains why the world should pay attention.

In a much closer contest than previous years – when the tardigrade and the common earthworm won with popular landslides – the winner of the 2026 Guardian Invertebrate of the year has been decided.
The competition was launched three years ago to celebrate overlooked and often derided invertebrates, which number at least 1.7m species – about 97% of all animals – with probably millions more still to be discovered and described.
Watch presenter and naturalist Chris Packham run down the top three to reveal the winner.

Most allotment holders say the heat has meant more work for smaller crops, although some have found a silver lining
After a summer of repeated heatwaves and exceptionally dry weather in the UK, rain has brought some relief this week, but drought remains widespread and experts warn it will take weeks of sustained rainfall for water supplies to recover.
For people growing their own fruit and vegetables, it has been a challenging and sometimes surprising season. The Guardian spoke to growers across England about how they are adapting to a hotter, drier climate.

Novice gardeners James Reed McGuire and Crystal Fritz wanted to try something new when they moved out to the suburbs. Little did they know they were joining a nationwide movement
When James Reed McGuire and Crystal Fritz first decided to replace their lawn with native plants, they did not really know what they were doing. As former city-dwellers who had moved from Chicago out to the suburb of Highland Park, Illinois, they had never done much gardening together beyond growing some planters of herbs and flowers on their balcony.
But for McGuire, an avid birder who did not want to live with a sea of turf that does “absolutely nothing for the environment”, figuring out an alternative to the suburban status quo was imperative.

This punishingly hot and dry summer will probably be followed by another wet winter. But it’s nothing compared with what Britain will endure in years to come
This summer could be the hottest, driest and deadliest in English history. Successive heatwaves have so far claimed almost 3,000 lives. Nearly three-quarters of England and all of Wales is in drought, while key reservoirs are parched. Across this brown and stickily unpleasant land, from Grimsby down to St Ives, hosepipe bans are in force, while music festivals are staged not on green fields but in giant dust bowls.
Just how bad is it? I asked a leading climate scientist.

Andy Burnham promises drive to tackle toxic waste, raise fines and use AI-powered drones to detect illegal activity
Illegal dumps in West Yorkshire, Surrey and Kent will be cleared up using taxpayer money, Andy Burnham has announced, as the prime minister promises a new drive to tackle toxic waste.
Ministers have identified dumps in Bradford, Runnymede and the Isle of Sheppey, which collectively contain about 22,000 tonnes of illegal waste, to be cleared in the next phase of the government’s national clear-up effort.

The overpopulation of axis deer has taken an environmental toll, but Maui Nui Venison sees it as a resource instead of a pest
In 1868, the government of Hong Kong gave eight axis deer to Hawaii’s King Kamehameha V. They were a beautiful gift, these creatures that hail from south Asia, with their honey-colored pelts marked by a smattering of white spots. But their incursion into Maui started much later, in the 1950s, when they were brought to the island for recreational hunters.
Now, more than a century after their introduction, an estimated 60,000 traverse the Hawaiian islands of Lanai, Maui and Molokai in herds that are reshaping the environment. Unlike the white-tailed deer common along the US east coast, whose breeding season lasts from October to January, axis deer breed year-round. Their herds are constantly reduplicating. They feast on native grasses and endangered plants, chewing them down to their roots, leaving wide swathes of lands fallow. They can leap 10ft over fencing or barrel through it, consuming farmers’ crops and the cattle feed needed for Maui’s small beef industry.

Crustaceans are the subject of tests to see if alkalis added to seawater, so it absorbs more CO2, harm marine life. But Trump’s halt to funding threatens to scupper the research
For many in the US region of New England, the lobster roll is synonymous with summertime. Loaded into a toasted bun, chunks of the sweet meat are served hot and soaked in butter, or chilled and slathered in mayonnaise with celery and herbs.
The only thing more debated than the recipe is the price: the once-humble roll now routinely fetches $30 (£22), or even $50, in a sign of the changing times – and seas.

The leaf sheep, a neon green solar-powered slug, has inspired at least one Pokémon character and triumphs in global ballot
A neon green solar-powered slug that lives underwater is the winner of the increasingly popular Invertebrate of the Year competition run by the Guardian.
The leaf sheep, Costasiella kuroshimae, triumphed in the global ballot after hundreds of thousands of readers around the world read about and shared their appreciation for the spineless creatures who make up the majority of animal life on Earth.

Five hundred people turn up to adopt plants from conservatory that will reopen in 2030 after renovation project
Above the waxy monstera leaves and bright pink hibiscus flowers in the Barbican conservatory hangs a giant net to catch the panes of glass that are at risk of falling from the ceiling on the unwitting plant lovers below.
This precarious situation has caused the estate to shutter its greenhouse on the third and fourth floors for three years so a full refurbishment can take place. But the hiatus has a silver lining for many of those who visited on Wednesday to give the plants from the conservatory a new home.

Američki znanstvenici otkrili su da u predkliničkim modelima raka debelog crijeva tumori mogu početi oštećivati periferne živce prije početka kemoterapije. Ovi rezultati sugeriraju da upala povezana s tumorom i promjene u metabolizmu masti mogu oštetiti zaštitni omotač oko živaca, poremetivši signale i potencijalno ih čineći osjetljivijima na perifernu neuropatiju ili oštećenje živaca uzrokovano liječenjem.
Spoj koji se proizvodi u tijelu nakon jedenja nara poboljšava funkciju srca do 80% kod vrste zatajenja srca s ograničenim mogućnostima liječenja, pokazala je britanska studija. Naime, pokazalo se da urolitin A - prirodni spoj koji se proizvodi u tijelu nakon konzumiranja hrane poput nara, oraha i nekih bobičastih plodova - poboljšava sposobnost srca da se opusti, smanjuje ožiljke i sprječava štetno povećanje srca.
U nedavno objavljenom istraživanju pokazalo se da je prehrana bogata antioksidansima povezana s nižim rizikom od raka vrata maternice kod žena. Smatra se, da ovi rezultati sugeriraju da unos antioksidansa u prehrani može igrati potencijalnu ulogu u prevenciji raka vrata maternice.
Nova studija sugerira da se Alzheimerova bolest može otkriti snimanjem mozga više od sedam godina ranije nego što se prije pretpostavljalo. Naime, otkrivene su strukturne promjene u mozgu koje se događaju mnogo godina prije nego što se visoke razine amiloid-beta plaka vide na PET snimkama, što je snimanje mozga koje se trenutno koristi za identifikaciju najranijih znakova Alzheimerove bolesti.
Prema rezultatima novog istraživanja, fluktuacije estrogena utječu na mozak, pomažući u preoblikovanju veza između neurona. Pokazalo se da specijalizirana tehnika snimanja nazvana magnetska rezonantna elastografija (MRE) može otkriti mehaničke promjene ovisne o estrogenu u hipokampusu, području mozga uključenom u pamćenje i učenje, tijekom reproduktivnog ciklusa.
Imunoterapija je transformirala liječenje raka, no mnogi tumori ostaju otporni na njezine učinke. Među najizazovnijima su tzv. hladni tumori, uključujući rak jajnika, rak dojke i rak prostate, koji izbjegavaju imunološki napad i slabo reagiraju na postojeće imunoterapije. Iako je poznato da kronični okolišni i metabolički stres oštećuju imunološke funkcije, kako dugoročni okolišni i prehrambeni stres reprogramira prirodne stanice ubojice (NK), ostalo je slabo shvaćeno.
Otprilike 65% odraslih osoba u SAD-u izvještava da svakodnevno konzumiraju jedno ili više napitaka zaslađenih šećerom. Znanstvenici Instituta za rak Mass General Brigham otkrili su da je svakodnevna konzumacija ovih napitaka povezana s povećanim rizikom od razvoja raka želuca.
Novi pregled otkriva da cjelovita, minimalno prerađena biljna hrana nudi najjače metaboličke koristi, dok rafinirana hrana, slatka pića i prekomjerno crveno i prerađeno meso mogu potkopati prevenciju i kontrolu dijabetesa.
Osobe koje žive s teškim mentalnim bolestima suočavaju se sa znatno većim rizikom od demencije tijekom odrasle dobi, kao i sa značajno povećanim rizikom od moždanog udara u ranoj i srednjoj odrasloj dobi, pokazuje nova studija.
Ulcerozni kolitis je kronična upalna bolest crijeva kod koje je teško kontrolirati ponavljajuću crijevnu upalu dugoročno. Trenutni tretmani uključuju 5-aminosalicilnu kiselinu (5-ASA), kortikosteroide, imunomodulatore, biološke lijekove i terapije malih molekula, ali otpornost na lijekove i nuspojave ostaju važna klinička pitanja.
