  • Exclusive: Fixing a leak can be simple and equivalent to closing a coal power station, making lack of action maddening, say analysts

    The world’s worst mega-leaks of the potent greenhouse gas methane in 2025 have been revealed by an analysis of satellite data.

    The super-polluting plumes from oil and gas facilities have a colossal heating impact on the climate but often result from poor maintenance and can be simple to fix. The assessment found dozens of mega-leaks, each having the same global heating impact as a coal-fired power station.

  • Our photojournalist explores the Cornish landmark on the eve of its anniversary and meets some of its staff, visitors, plants and creatures

    “Give me a sleeping bag and I’ll happily sleep here overnight,” says Kim Mackintosh as she wanders amid the vibrant flora of the Mediterranean biome at the Eden Project on the eve of the tourist attraction’s 25th anniversary.

    Loupe in hand, the leader of the biome’s horticulture team is marvelling at an array of plants that have recently come into bloom, tenderly examining the yellow furry buds of an Acacia glaucoptera before flogging a Grevillea flower to dispense its rich, honey-flavoured nectar.

  • Drosopigi, the Mani, Greece: This rocky region’s abundance of flora takes the breath away – not least a long and winding trail of Chios chamomile

    The Greek name for this southernmost tip of the Peloponnese is linked to a Byzantine fort at Cape Tigani (called Megali Maina), but it may well also draw on the region’s desolate, mountainous rocky country that persists throughout the entire peninsula.

    The fierce Maniot people were well described by Patrick Leigh Fermor in his book Mani (1958), but the region has been more recently celebrated in Charles Foster’s brilliant The Edges of the World, published in January. In history the Mani was known variously for the relentless and sometimes centuries-long vendettas between its local clans, as a fertile recruiting ground for Mediterranean piracy and as an early outpost for Greek liberation from Ottoman rule.

  • Researchers project that reduced activity could contribute to half a million additional premature deaths annually by 2050

    Rising temperatures are making physical activity undesirable and even dangerous in many parts of the world, and as global heating worsens, it will further affect how much people are able to move.

    Researchers analysed data from 156 countries between 2000 and 2022 and modelled how rising temperatures may affect physical activity globally by 2050.

  • Exclusive: Claire Earley’s son Rex spent six weeks in hospital after contracting E coli from contaminated lake

    Realtime pollution alerts are needed across Windermere urgently, campaigners have said, as the mother of a seven-year-old boy who kayaked on the lake described how he nearly died after contracting a dangerous strain of E coli from contaminated water.

    Claire Earley’s son Rex spent six weeks in hospital, and underwent two emergency operations, after a family kayaking trip on Windermere last August.

  • Recording of humpback whale from 1949 could also provide new understanding of how the huge animals communicate

    A haunting whale song discovered on decades-old audio equipment could open up a new understanding of how the huge animals communicate, according to researchers who say it is the oldest such recording known.

    The song is that of a humpback whale, a marine giant beloved by whale watchers for its docile nature and spectacular leaps from the water, and was recorded by scientists in March 1949 in Bermuda, said researchers at Woods Hole Oceanographic Institution in Falmouth, Massachusetts.

  • Falling costs and government incentives made solar an attractive option for many, which has reduced need for gas

    After prices of liquefied natural gas surged to record highs following Russia’s full-scale invasion of Ukraine in 2022, millions of people in Pakistan were repeatedly left without electricity. An intense heatwave and gas shortages amid record-breaking prices resulted in power cuts across the country.

    But people soon started to realise there was an alternative. The falling costs of solar panels and generous government incentives to feed excess power back to the grid made rooftop solar an attractive option.

  • Water shortages and rising heat is putting pressure on beer ingredients, but US brewers and farmers are adapting

    With St Patrick’s Day this week, millions of Americans are raising a glass. Beer remains the country’s most popular alcoholic drink with more than 6bn gallons consumed each year. But from water shortages to rising temperatures, the climate crisis is putting pressure on beer’s most essential ingredients.

    At Deschutes Brewery in Bend, Oregon, beer is either stacked high in warehouse rows or racing down a canning line and assembled into 12-packs. Inside the cavernous cellars, enormous 6,000-gallon tanks hold the latest batches in progress.

  • The Quapaw Nation is the only US Native community to carry out a cleanup of one of the country’s worst sites of environmental contamination

    They call this land the Laue. In the late 1800s, part of these 200 acres of grassland inside the Quapaw Nation were allotted to tribal citizen Charley Quapaw Blackhawk. After forcing dozens of tribes into Indian territory before the civil war, the US government then parceled out reservations and property to individual members. It was part of the government’s attempt to “civilize” Native Americans by turning them into private, not communal,landholders and yeoman farmers in the model of Thomas Jefferson’s ideal citizen.

    Yet, for the last century, little grew on the Laue. Half of it was buried beneath towering mounds of toxic rock known as chat piles. The waste rock, laced with chemicals, was left after miners extracted millions of tons of lead and zinc from the Tri-State Mining District, where the valuable ores stretched across Kansas, Missouri and Oklahomabetween 1891 and the 1970s. By 1983, the Environmental Protection Agency (EPA) had designated 40 sq miles that include nearly all the Quapaw Nation as the Tar Creek Superfund site, joining the EPA’s list of the most contaminated places in the country. Informally called a “megasite”, Tar Creek remains one of the largest and most complex environmental disasters in the country.

  • Jednostavan plan vježbanja kod kuće pomogao je pacijentima da ostanu aktivni tijekom kemoterapije, smanjujući mentalni umor i pokazujući potencijal za ublažavanje kemo mozga, posebno kod onih na kraćim ciklusima liječenja, pokazala je nova studija.

  • Japanski registar identificirao je slijepu točku u rutinskoj skrbi pacijenata s kroničnom bolešću bubrega (CKD). Razina bikarbonata u serumu rijetko se mjeri, što metaboličku acidozu uglavnom ostavlja neotkrivenom i stoga nedovoljno liječenom. Metabolička acidoza česta je komplikacija kronične bubrežne bolesti i povezana je s gubitkom mišićne mase, bolestima kostiju, inzulinskom rezistencijom, ubrzanim propadanjem bubrega i povećanom smrtnošću. Kliničke smjernice preporučuju liječenje kada razina bikarbonata u serumu padne ispod 22 mEq/L.

  • Rezultati nove studije sugeriraju da bi povećanje unosa mlijeka na preporučene razine moglo smanjiti učestalost moždanog udara i smanjiti nacionalne troškove zdravstvene zaštite povezane s moždanim udarom, ističući kako male promjene u prehrani mogu donijeti značajne dobitke za javno zdravstvo.

  • Stres u ranom životu može dovesti do probavnih problema kasnije u životu, uzrokovan promjenama u crijevima i simpatičkom živčanom sustavu, tvrdi nova studija. Naime, ova studija pokazuje da stresori mogu imati stvaran utjecaj na razvoj djeteta i dugoročno utjecati na probleme s crijevima, a razumijevanje uključenih mehanizama može pomoći u stvaranju ciljanijih terapija.

  • Kolorektalni karcinom ostaje jedan od vodećih uzroka smrtnosti povezane s rakom u svijetu, uglavnom zbog metastaza i ograničenog odgovora na imunoterapiju kod većine pacijenata. Iako su inhibitori imunoloških kontrolnih točaka transformirali liječenje određenih podtipova tumora, većina kolorektalnih karcinoma ostaje "imuno-hladna", što znači da ne uspijevaju pokrenuti učinkovit antitumorski imunitet.

  • Upala, obilježje Crohnove bolesti, donosi nakupine ili agregate imunoloških stanica u submukozu. Koristeći sekvenciranje RNK pojedinačnih stanica (scRNA-seq) za proučavanje fibroze kod Crohnove bolesti, znanstvenici su otkrili neobično nakupljavanje endotelnih stanica - stanica koje obično oblažu krvne žile - oko ovih skupina imunoloških stanica (poznatih kao Crohnovi limfoidni agregati ili CLA). Ove nakupine stanica krvnih žila signaliziraju stanicama koje grade ožiljke (fibroblasti/miofibroblasti) izravno ili putem makrofaga da počnu proizvoditi prekomjernu količinu kolagena ili ožiljnog tkiva, što sugerira da ovi Crohnovi limfoidni agregati mogu imati značajnu ulogu u pokretanju procesa fibroze.

  • Znanstvenici otkrivaju kako promjene u vaginalnom mikrobiomu tijekom trudnoće mogu utjecati na upalu i rizik od prijevremenog poroda, ukazujući na nove terapije temeljene na mikrobiomu koje bi mogle poboljšati zdravstvene ishode majke i dojenčadi. Jednako tako, studija ističe dokaze koji upućuju na to da je okruženje u kojem dominiraju Lactobacillusi obično povezano s imunološkom tolerancijom, dok je disbioza povezana s fiziološki štetnim upalnim kaskadama.

  • Studija provedena na gotovo 16.000 odraslih osoba sugerira da često preskakanje doručka može biti povezano s većom vjerojatnošću razvoja metaboličkog sindroma, glavnog faktora rizika za srčane bolesti. Budući da je metabolički sindrom glavni faktor rizika za kardiovaskularne bolesti, ovi rezultati ističu potencijalnu važnost redovite konzumacije doručka radi poboljšanja kardiometaboličkog zdravlja.

  • Gotovo svi duktalni adenokarcinomi gušterače (PDAC) nastaju aktiviranjem mutacija u onkogenu KRAS, koje se javljaju u više različitih alelnih oblika. Iako su značajni napori doveli do razvoja inhibitora koji ciljaju specifične mutantne KRAS proteine, jedini agensi trenutno odobreni za kliničku upotrebu selektivno ciljaju varijantu KRASG12C. Međutim, mutacije KRASG12C su izuzetno rijetke kod raka gušterače.

  • Nedostatak vitamina B2 čini tumorske stanice osjetljivijima na jedinstveni oblik stanične smrti, pokazala je nova studija. Ljudsko tijelo ne može samo proizvesti vitamin B2, poznat i kao riboflavin, te ga mora apsorbirati putem prehrane. Vitamin B2 se može naći u mliječnim proizvodima, jajima, mesu i zelenom povrću. Metabolizam ga pretvara u molekule koje, između ostalog, štite stanicu od oksidativnog oštećenja. No, sada je nova studija pokazala da ova funkcija vitamina B2 ima i lošu stranu: također štiti stanice raka. Naime, vitamin B2 igra ključnu ulogu u zaštiti stanica raka od feroptoze, posebnog oblika programirane stanične smrti.
