Santa Marta conference born out of frustration at Cop summits, where renewable progress has been stalled by major polluters
Everybody knows fossil fuels cause climate breakdown, but until recently, mention of them was all but erased from the annual UN climate summits. Last year, two weeks of discussions ended without fossil fuels being mentioned in the final outcome.
Frustration with those talks led a small developing country with a large fossil fuel sector – Colombia, the largest coal and fourth biggest oil exporter in the Americas – to rewrite the rules. With co-convener the Netherlands, and support from more than 50 countries, Colombia will host a groundbreaking new global conference this month to begin the long-awaited “transition away from fossil fuels”.

Scientists say finding is ‘very concerning’ as collapse would be catastrophic for Europe, Africa and the Americas
The critical Atlantic current system appears significantly more likely to collapse than previously thought after new research found that climate models predicting the biggest slowdown are the most realistic. Scientists called the new finding “very concerning” as a collapse would have catastrophic consequences for Europe, Africa and the Americas.
The Atlantic meridional overturning circulation (Amoc) is a major part of the global climate system and was already known to be at its weakest for 1,600 years as a result of the climate crisis. Scientists spotted warning signs of a tipping point in 2021 and know that the Amoc has collapsed in the Earth’s past.

Exclusive: Experts say scheme will help repair damaged marine ecosystems while sequestering large amounts of carbon
More than 15m juvenile oysters are to be released into the North Sea in one of the biggest rewilding projects in UK waters.
The scheme, which will use a unique rearing process, hopes to re-establish a huge oyster bed around Orkney that experts say will create a “trophic cascade” of climate and ecological benefits.

Pollution is ‘silent accelerator that robs individuals of their healthiest years’, say researchers
Research reveals air pollution is advancing the average age that people in the UK acquire long-term illnesses. For some conditions people could be getting ill more than two years earlier because of the air pollution they breathe.
The first author of the research from Prof Hualiang Lin’s group at Sun Yat-sen University said: “Our study demonstrates that air pollution is not just a risk factor for falling ill; it acts as a silent accelerator that robs individuals of their healthiest years.”

Legally questionable confidentiality clause adopted almost word for word from demands of Microsoft and trade groups
Microsoft and other US tech companies successfully lobbied the EU to hide the environmental toll of their datacentres, an investigation has found, with demands to block a database of green metrics from public view written almost word for word into EU rules.
The secrecy provision, which the European Commission added to its proposal almost verbatim after industry lobbying in 2024, hinders scrutiny of the pollution that individual datacentres emit. It leaves researchers with just national-level summaries of their energy footprints.

Lower Botanic Gardens, Belfast:A precious field here provides flood protection and carbon research, and has a productive community garden. Still, it is in jeopardy
Among many languages on the poster at the field’s entrance gate is a declaration in Ulster-Scots: This be oor fiel. Close to my home in the heart of an urban landscape, “our field” in Lower Botanic Gardens invites my idle wandering.
Going by the desire paths that crisscross its floodplain meadow, I follow in many footsteps. Recently rewilded and recultivated for a new age, this council-owned field has always responded to the needs of the times. The field grew vegetables during the second world war, and grew families in prefabricated housing after that war ended. Today, in subtle and transformative ways, this cherished place still provides for and protects local people.

From rainwater harvesting to tree nurseries, communities in Medellín are taking steps to increase their landslide and flooding resilience
In his home on a steep hillside in the neighbourhood of Golondrinas in Medellín, Róbinson Velásquez Cartagena stands proudly next to two large tanks of water – a rainwater harvesting system he designed and built to help reduce the risk of flooding and landslides.
It is one of the nature-based solutions that Velásquez and others in the community have proposed as part of a disaster risk and climate crisis adaptation plan for Comuna 8, a growing informal settlement of 150,000 people in Colombia’s second-largest city.

Seven deaths and 15 injuries have been recorded in the past year as crocodiles move their habitats closer to human settlements
• Warning: contains graphic descriptions of crocodile attacks
Ng’ikalei Loito was walking out of the warm waters of Lake Turkana on a sunny afternoon, having just finished swimming with her two sisters-in-law, when she suddenly felt the crushing force of a crocodile’s bite on her legs.
In excruciating pain, she instinctively clung to a partially submerged tree that was within reach and screamed for help, as the crocodile tried to drag her under the water.

Energy crisis unfolding in Middle East has added political urgency, and more funding, to transform South Korea’s solar industry
In Guyang-ri, a farming village of 70 households about 90 minutes south-east of Seoul, people gather for communal free lunches six days a week. The meals are funded by the village’s one-megawatt solar installation, which generates roughly 10m won ($6,800) in net profit each month.
“Residents eat lunch together every day, so we see each other’s faces, talk together,” says Jeon Joo-young, the village chief. “Bonds and solidarity between residents become much stronger. Life becomes more enjoyable.”

Određivanje prisutnosti proteina u netumorskim stanicama unutar mikrookruženja raka moglo bi biti jedan od ključeva za utvrđivanje prognoze kod pacijenata s rakom debelog crijeva. Također, to može pomoći u utvrđivanju koji bi pacijenti mogli imati koristi od imunoterapije ili od tretmana usmjerenih na inhibiciju specifičnog proteina povezanog s proliferacijom tumora.
Aortne aneurizme karakterizira abnormalno povećanje aorte, primarne arterije odgovorne za prenošenje krvi iz srca. Ruptura često dovodi do iznenadne smrti, a trenutno nema učinkovitih terapija lijekovima za zaustavljanje napredovanja bolesti. Sada su japanski znanstvenici otkrili da su aortne aneurizme povezane s klonskom hematopoezom, procesom povezanim sa starenjem u kojem matične stanice koje stvaraju krv stječu genetske mutacije.
Odrasli koji su izjavili da se osjećaju usamljeno imali su veći rizik od razvoja degenerativne bolesti srčanih zalistaka, čak i nakon što su uzeti u obzir tradicionalni faktori rizika za srčane bolesti i genetika, pokazuje nova studija.
Nova studija pokazuje da aktivni mitohondriji održavaju dendritične stanice, stražare imunološkog sustava, u stanju spremnosti za odgovor, povezujući stanični metabolizam s regulacijom gena i aktivacijom T-stanica. Smatra se, da ovo otkriće otvara nove puteve za poboljšanje cjepiva i imunoterapije raka.
Daraksonrasib, lijek tvrtke Revolution Medicines za rak gušterače, uspio je u dugo očekivanom kliničkom ispitivanju faze III, gotovo udvostručivši tipično trajanje preživljavanja i smanjivši rizik od smrti za 60% u odnosu na kemoterapiju.
Crijevne bakterije mogle bi uzrokovati probleme djece s rijetkim, ali ozbiljnim stanjem alergije na hranu, tvrdi nova studija. Naime, djeca sa sindromom enterokolitisa induciranog proteinima hrane (FPIES) imaju profile crijevnih bakterija koji se značajno razlikuju od profila kod zdrave djece.
Prema rezultatima novog istraživanja, rizik od razvoja demencije značajno je veći u osoba koje koriste e-cigarete. Jednako tako, pokazalo se, da je znatno veći udio korisnika e-cigareta (39,7%) klasificiran kao rizičan za kognitivno oštećenje u usporedbi s nepušačima (0,9%) (p < 0,001).
Velika studija je pokazala da se posttrombotski sindrom - česta i često bolna komplikacija od koje pate mnogi ljudi koji su doživjeli začepljenje glavnih vena zbog krvnih ugrušaka - može učinkovito liječiti minimalno invazivnim postupkom. Naime, studija je otkrila da postavljanje stenta za otvaranje i jačanje zahvaćene vene smanjuje težinu posttrombotskog sindroma te poboljšava venske simptome i ukupnu kvalitetu života kod oboljelih pacijenata.
Rezultati kliničkog ispitivanja faze 2 koje su osmislili i nadzirali znanstvenici s Mass General Brigham Cancer Institute, pokazuju da ispitivani lijek mezagitamab može učinkovito povećati broj trombocita kod pacijenata s imunom trombocitopenijom (ITP), autoimunom bolešću koju karakterizira povećano uništavanje trombocita i smanjena proizvodnja trombocita, što povećava rizik od krvarenja i ugrožava kvalitetu života.
Rezultati nove studije otkrivaju kako veći broj koraka može suzbiti neke štete dugotrajnog sjedenja, no istovremeno upozoravaju da previše vremena provedenog u sjedenju i dalje nosi trajne rizike za srce. Inače, više od jedne trećine odraslih osoba provodi dulje vrijeme u sjedilačkom ponašanju, iako je to povezano s većim rizikom od kroničnih bolesti i prerane smrti.
