Researchers say sediment changes due to waste dumping and coastal erosion intensified by climate breakdown
As much as half of some British beaches’ coarse sediments consist of human-made materials such as brick, concrete, glass and industrial waste, a study has found.
Climate breakdown, which has caused more frequent and destructive coastal storms, has led to an increase in these substances on beaches. Six sites on the Firth of Forth, an estuary on Scotland’s east coast joining the River Forth to the North Sea, were surveyed to better understand the makeup of “urban beaches”.

Ministers’ proposals to tackle ‘forever chemicals’ fail to match tougher stance taken in Europe, say experts
Environmental campaigners have criticised a “crushingly disappointing” UK government plan to tackle “forever chemicals”, which they warn risks locking in decades of avoidable harm to people and the environment.
The government said its Pfas action plan set out a “clear framework” of “coordinated action … to understand where these chemicals are coming from, how they spread and how to reduce public and environmental exposure”.

Chagossian people would be allowed to fish in area that has teemed with life since ban was introduced in 2010
One of the most precious marine reserves in the world, home to sharks, turtles and rare tropical fish, will be opened to some fishing for the first time in 16 years under the UK government’s dealto hand back the Chagos Islands to Mauritius.
Allowing non-commercial fishing in the marine protected area (MPA) is seen as an essential part of the Chagossian people’s return to the islands, as the community previously relied on fishing as their main livelihood. But some conservationists have raised the alarm, as nature has thrived in the waters of the Indian Ocean since it was protected from fishing.

Sector bounces back as consumers focus on provenance and healthy eating, but is still well behind Europe
Consumers searching for healthy food from trusted sources have fuelled the UK organic market’s biggest boom in two decades, according to vegetable box seller Riverford.
The delivery business, which sells meat, cheese, cookbooks and recipe boxes alongside vegetables, recorded a 6% increase in sales to £117m in the year to May 2025, as the UK organic food and drink market grew by almost 9% in that year, according to new figures from the Soil Association. The strong growth, significantly outpacing the wider food market, helped the employee-owned business give a £1.1m bonus to workers.

Priestcliffe, Derbyshire:The limestone walls in this parish are festooned with luminous mosses, in a variety that’s often beyond our comprehension
The word bryophyte refers to a group of plants that may have colonised terrestrial Earth almost half a billion years ago. They need water to reproduce sexually and they love rain. So it’s hardly surprising that Britain is an important archipelago for them, with the two main groups, liverwort and mosses, represented by nearly 300 and 770 species respectively. This is a 20th of all the world’s bryophytes.
Perhaps the best summary of the British public’s sense of the group was offered by a friend recently, who said that he hadn’t been aware that there was more than one bryophyte. Moss doesn’t occupy our conscious minds. It lives at the periphery, trembling on the edge of our sense of things. Especially when it rains, because moss is then even more luminous.

Volunteer workers say increasing case numbers and dozens of dead birds raise fears spread is wider than recorded
Members of the public and charity volunteers are working to contain a suspected outbreak of bird flu among swans in the Thames Valley, amid signs that confirmed cases are continuing to rise.
Since October, 324 cases of bird flu in swans have been recorded by the Animal and Plant Health Agency (Apha), which is sponsored by the Department for Environment, Food and Rural Affairs (Defra). Of these, 39 were recorded in the first four weeks of 2026 alone.

With some of Ukraine’s most valuable biodiversity sites and science facilities under occupation, experts at Sofiyivka Park in Uman are struggling to preserve the country’s natural history
In the basement laboratory of the National Dendrological Park Sofiyivka, Larisa Kolder tends to dozens of specimens of Moehringia hypanicabetween power outages. Just months earlier, she and her team at this microclonal plant propagation laboratory in Uman, Ukraine, received 23 seeds of the rare flower.
Listed as threatened in Ukraine’s Red Book of endangered species, Moehringiagrows nowhere else in the wild but the Mykolaiv region of Ukraine. Of those 23 seeds, only two grew into plants that Kolder and her colleagues could clone in their laboratory, but now her lab is home to a small grove of Moehringiaseedlings, including 80 that have put down roots in a small but vital win for biodiversity conservation amid Russia’s war with Ukraine.

With government action stalled and living in ‘inhumane’ conditions, families in San José are making plans to relocate
In Emilio Peña Delgado’s home, several photos hang on the wall. One shows him standing in front of a statue with his wife and oldest son in the centre of San José and smiling. In another, his two sons sit in front of caricatures from the film Cars. For him, the photos capture moments of joy that feel distant when he returns home to La Carpio, a neighbourhood on the outskirts of Costa Rica’s capital.
Delgado migrated with his family from Nicaragua to Costa Rica when he was 10, as his parents sought greater stability. When he started a family of his own, his greatest hope was to give his children the security he had lacked. But now, that hope is often interrupted by the threat of extreme weather events.

Support from more than 20 countries propels National Trust to its target to protect chalk figure and local wildlife
It feels like a very British monument: a huge chalk figure carved into a steep Dorset hillside that for centuries has intrigued lovers of English folklore and legend. But an appeal to raise money to help protect the Cerne giant – and the wildlife that shares the landscape it towers over – has shown that its allure stretches far beyond the UK.
Donations have flooded in from more than 20 countries including Australia, Japan and Iceland, and on Tuesday, the National Trust confirmed it had reached its fundraising target to buy land around the giant.

Events such as Storm Chandra take a terrible toll on ecosystems, but nature can be part of the solution for mitigating flood waters
“The flood waters are only good for scavenger species,” says Steve Hussey, searching hard for a silver lining to last week’s deluges brought by Storm Chandra. When the waters recede, crows and ravens will feast on the carrion of hedgehogs, dormice and other small animals unable to escape the rising water, he says.
“It sounds very apocalyptic, doesn’t it?” says Hussey, a communications officer with the Devon Wildlife Trust.

Strategija prevencije koju su razvili kanadski znanstvenici može smanjiti rizik od najčešćeg i najsmrtonosnijeg oblika raka jajnika za gotovo 80 posto, tvrde rezultati nove studije. Strategija, poznata kao oportunistička salpingektomija (OS), uključuje proaktivno uklanjanje jajovoda osobe kada već prolazi kroz rutinsku ginekologiju poput histerektomije ili podvezivanja jajovoda, što se obično naziva podvezivanje jajovoda.
Signali popravka DNK i integriranog odgovora na stres (ISR) u krvi otkrivaju kratki molekularni prozor koji prethodi dijagnozi Parkinsonove bolesti, pokazala je nova studija. Parkinsonova bolest je progresivni neurodegenerativni poremećaj karakteriziran motoričkim simptomima, poput bradikinezije, posturalne nestabilnosti, tremora i ukočenosti, koji se pojavljuju tek nakon značajne neurodegeneracije.
Analizirajući tkivo pacijenata s Parkinsonovom bolešću te životinjske i stanične modele bolesti, španjolski znanstvenici s INc-UAB otkrili su da glavne imunološke stanice mozga postaju reaktivne i prekomjerno eksprimiraju određene receptore koji potiču eliminaciju dopaminergičnih neurona, čak i kada su ti neuroni još uvijek funkcionalni. Studija ukazuje na novi pristup imunoterapiji koji bi mogao pomoći u očuvanju održivih neurona kod osoba s ovom dijagnozom.
Dvoje od troje adolescenata sa sindromom iritabilnog crijeva (IBS) započinje odraslu dob bez bolesti, tvrde rezultati dugoročne studije koja je pratila više od 2.500 ispitanika. Simptomi IBS-a često uključuju dugotrajne bolove u trbuhu, zatvor ili proljev, neredovitu stolicu i plinove. Iako se smatra da čimbenici u ranoj dobi igraju ulogu u razvoju bolesti, istraživanja u ovom području su ograničena - posebno u odnosu na prijelaz iz adolescencije u odraslu dob.
Chlamydia pneumoniae - uobičajena bakterija koja uzrokuje upalu pluća i infekcije sinusa - može se godinama zadržati u oku i mozgu te može pogoršati Alzheimerovu bolest, pokazuje nova studija. Ovo otkriće sugerira da ova bakterija može pojačati Alzheimerovu bolest i ukazuje na potencijalne intervencije, uključujući terapije za ograničavanje upale i rano liječenje antibioticima.
Hordom je rijedak tumor karakteriziran lošom prognozom, ograničenim terapijskim mogućnostima i visokom stopom ponovne pojave. Unatoč napretku u onkologiji, učinkoviti tretmani za hordom ostaju ograničeni. Otpornost na konvencionalnu radioterapiju i kemoterapiju ograničava terapijske mogućnosti, a kirurško liječenje često je izazovno zbog blizine tumora kritičnim anatomskim strukturama. Posljedično, identificiranje novih terapijskih ciljeva ključno je za poboljšanje dijagnoze hordoma, strategija liječenja i predviđanja ishoda.
Dodavanje palbocikliba anti-HER2 i endokrinoj terapiji, nakon indukcijske kemoterapije, može odgoditi napredovanje bolesti kod pacijenata s metastatskim rakom dojke pozitivnim na hormonske receptore (HR+) i pozitivnim na receptor 2 humanog epidermalnog faktora rasta (HER2+), pokazala je nova studija. Rezultati su pokazali medijan preživljavanja bez progresije bolesti od 44,3 mjeseca u skupini koja je primala palbociklib, u usporedbi s 29,1 mjesecom u kontrolnoj skupini.
Znanstvenici su razvili način uzgoja visoko specijaliziranog podskupa moždanih živčanih stanica koje su uključene u bolesti motornih neurona i oštećene su kod ozljeda kralježnice. Smatra se, da ovo postignuće postavlja temelje za daljnja istraživanja o tome mogu li ovi molekularno usmjereni neuroni formirati funkcionalne veze u tijelu i za istraživanje njihove potencijalne upotrebe u ljudskim bolestima gdje su kortikospinalni neuroni ugroženi.
Međunarodni tim znanstvenika otkrio je stotine gena i proteina koji vjerojatno igraju uzročnu ulogu u dijabetesu tipa 2, od kojih bi mnogi bili propušteni studijama koje se oslanjaju samo na uzorke krvi. Nova studija pokazuje da su biološki mehanizmi koji leže u osnovi dijabetesa tipa 2 vrlo tkivno specifični i da je genetska raznolikost u populacijama ključna za identificiranje pokretača bolesti.
Nova studija otkriva kako bakterije u crijevima mogu pomoći u određivanju hoće li aminokiselina asparagin iz prehrane hraniti rast tumora ili aktivirati imunološke stanice protiv raka. To crijevni mikrobiom, koji se sastoji od bilijuna mikroorganizama koji žive u crijevima, postavlja kao središnjeg igrača u odgovoru tijela na rak i na moderne tretmane raka poput imunoterapija.
