Exclusive: European Commission planning to rewrite key law to allow water-intensive mines in regions suffering from drought
The European Commission plans to rewrite the EU’s flagship water protection law to speed up the development of critical minerals mines, despite many being located in drying and water-stressed regions, analysis has found.
Mining is a water-intensive industry, requiring large volumes of water for ore processing, dust suppression, waste management and mine dewatering. While modern projects recycle water, they still require significant amounts, and in water-stressed regions those demands can add to pressure on already stretched rivers, aquifers and water supplies.

Blaenau Ffestiniog, Gwynedd: This living sculpture, planted in the 1970s ‘for the 21st century’, is fading fast. But heartbreak is not the only response
Ten years ago when I visited the Ash Dome, it was an elegant, twisting circle of beautiful trees. Ten years ago, ash dieback had not yet reached this corner of Wales. Returning now to this secret location, I steeled myself for heartbreak. And there it was.
Today, the Ash Dome, a living sculpture by the renowned artist David Nash, is an elephant’s graveyard. Pale, twisted limbs encircle a heap of dead branches. On a few trunks, new shoots spring innocently upwards, but most are ailing, their bark white and flaky as dead skin.

Apart from effort to electrify, there were geopolitical tensions around climate science and the 1.5C goal at pre-Cop31 climate talks
Electrifying the world – with electric vehicles, electric heating and cooling, and modernised heavy industry – could be the next biggest step towards phasing out fossil fuels, replacing the 80% of global energy that still comes from hydrocarbons. As using electrical energy is much more efficient than combustion, the move would save billions of dollars for consumers and businesses – global energy demand could be halved, according to one estimate.
For decades, electrification has been a nerdish backwater of global climate action. But in the last two weeks, at preparatory talks in Bonn before the forthcoming UN Cop31 climate summit, the subject finally took centre stage.

Experts cast doubt on conclusion of government-funded study of factory emitting forever chemicals near Blackpool
Questions have been raised about the conclusions drawn by a government-funded study into kidney cancer rates near a factory linked to forever chemicals near Blackpool.
Pfoa, a known carcinogenic forever chemical that was banned globally in 2020, was emitted from the AGC Chemicals Europe plant in Thornton-Cleveleys, near Blackpool, between the 1950s and 2012. An estimated 49 tonnes of Pfoa were emitted during that period. The factory, which AGC Chemicals Europe bought in 1999, stopped using Pfoa in 2012.

Move to dismantle $368m sea observatory initiative faced opposition from experts and lawmakers
The Donald Trump administration has reversed its decision to dismantle a $368m deep-sea observation system following an outcry from lawmakers and ocean experts.
On Thursday, the National Science Foundation announced that it would halt plans to dismantle the Ocean Observatories Initiative, stating: “effective immediately, [it] will not proceed with further removal or descoping of equipment from the remaining arrays and will continue operations including planned maintenance”.

Expansion could also hit access to housing, education, healthcare, open spaces and transport, analysis says
Construction of a third runway at Heathrow is likely to have significant adverse effects on the health and wellbeing of up to 3 million people living nearby, an official report has said, as the government launched the next stage of its rapid airport expansion plan.
An analysis for the Department for Transport (DfT) has found that expanding London’s hub airport could have “major adverse” impacts on the health of the most local population.

In this week’s newsletter: The melting of the Arctic’s summer sea ice is the most visible upshot of the climate crisis. Refreezing it might be a long shot – but do drastic times call for drastic measures?

Speeding across rapidly melting Arctic ice on a snowmobile gave me a vivid feel for its beauty and fragility. The brilliant white landscape gleamed ahead, while the sky blue pools of meltwater jetted up on to my boots.
When I visited Cambridge Bay in northern Canada at the start of this month, the melt season had hit with brutal speed: temperatures were 5-10C above normal, kickstarting the melting almost overnight.

Lanchester Wines in north-east England uses heat from a disused coalmine to maintain wine temperatures and with 23,000 flooded mines in the UK, there’s huge potential for more businesses and homes to follow its lead
Shove them in a fridge, stash them in a cellar – this is how most people store their favourite bottles of wine. But if you have warehouses full of thousands of vintages, you have to think a little differently.
For the last eight winters, Lanchester Wines has used heat from a disused coalmine to maintain ideal storage temperatures at its facilities in the north-east of England, helping to prevent freezing or spoilage.

As demand soars, the country’s mangrove forests and the livelihoods of shellfish gatherers are under threat from encroaching farms and unchecked pollution
At low tide, Johana Carolina Cruz Potes steps into the mudflats around Isla Costa Rica, in Ecuador’s Jambelí Archipelago. Holding a bucket and a short metal hook, she probes the tangled roots of a mangrove patch, searching for conchanegra, black-shelled cockles, buried beneath the sludge.
Cruz Potes has done this work since she was nine, when she first followed her father into the mud. But earning a living from shellfish gathering – often the only income for families here – has become harder as grounds shrink and catches decline.

A prospecting company’s search for gold has the town of Lone Pine and Indigenous leaders on edge, as the Trump administration greenlights new projects across the American west
Lone Pine, population 1,882, lies along a stretch of California highway framed by the vast Inyo mountains and a sweeping desert landscape of sagebrush and dunes.
It’s the type of small town tourists drive through en route to Death Valley; where hikers get a motel room between Pacific Crest Trail treks. But amid the quiet downtown strip of bars and shops, there are signs of a battle brewing under the town’s sleepy surface.

Zemlje s visokim prihodima koje su sredinom 2000-ih započele široko rasprostranjenu primjenu cjepiva protiv humanog papiloma virusa (HPV) doživjele su značajan pad slučajeva raka vrata maternice, što označava značajno postignuće u medicini.
Britanski znanstvenici prvi su put otkrili vezu između žvakanja žvakaće gume sa šećerom nakon konzumiranja povrća bogatog nitratima, poput cikle, špinata i kelja, i snižavanja krvnog tlaka. Povrće apsorbira nitrat iz tla, ali ga bakterije u ustima moraju pretvoriti u nitrit prije nego što ga tijelo može koristiti. Nitrit ima širok raspon učinaka, uključujući opuštanje i širenje krvnih žila, što omogućuje lakši protok krvi, snižavajući krvni tlak.
Trans-vakcenska kiselina (TVA), najzastupljenija transmasna kiselina koja se nalazi u majčinom mlijeku, pomaže u poticanju razvoja imunološkog sustava i ima dugotrajne učinke na zdravlje imunološkog sustava miševa, tvrdi nova studija.
Menopauza je povezana s nizom štetnih zdravstvenih učinaka, od kojih se neki mogu ublažiti nizom promjenjivih zdravstvenih ponašanja, uključujući prehranu, tjelovježbu i trajanje spavanja. Novo istraživanje nastojalo je utvrditi imaju li menopauza i status hormonske terapije ikakvu povezanost s promjenjivim zdravstvenim ponašanjima. Početni rezultati sugeriraju da veza postoji.
Mikroplastika – sićušni komadići plastike razgrađeni od većeg plastičnog otpada – sve su veća briga za ljudsko zdravlje, posebno za jetru. Sada nova studija pokazuje da je uobičajena vrsta mikroplastike posebno štetna za jetru u uvjetima prehrane s visokim udjelom masti.
Znanstvenici s Medicinskog fakulteta u Beču opisali su mehanizam u metastatskom raku debelog crijeva kojem se do sada posvećuje malo pažnje: ključna meta postojećih terapija, takozvani receptor epidermalnog faktora rasta (EGFR), vjerojatno utječe na više od samih stanica raka. Studija pokazuje da EGFR također utječe na određene imunološke stanice u mikrookruženju tumora - i time pomaže u određivanju koliko učinkovito vlastita obrana tijela može boriti se protiv tumora.
Lijek prethodno razvijen na UCLA-i kako bi pomogao srčanom tkivu da se popravi nakon srčanog udara također bi mogao pomoći u popravku i regeneraciji tkiva bubrega, pokazala je nova studija.
Prema rezultatima nove studije izgleda da odrasli koji jednostavno udišu pasivni dim cigareta imaju oko 1,5 puta više toksina kadmija u krvi od ljudi u okruženjima bez dima. Ovo je važna informacija jer se kadmij s vremenom nakuplja u tijelu i faktor je u raku bubrega, raku pluća i raku prostate.
Nova studija sugerira da bi jačanje prirodnih dnevnih ritmova tijela radi poboljšanja sna moglo pomoći mozgu da se oporavi nakon moždanog udara, što ukazuje na potencijalnu novu strategiju za poboljšanje uklanjanja otpada iz mozga i ishoda dugo nakon početne ozljede.
Vrsta bijelih krvnih stanica u imunološkom sustavu, poznata kao neutrofili, može smanjiti učinkovitost imunoterapije raka, tvrdi nova studija. Naime, rezultati pokazuju da signalna molekula u tumoru utječe na neutrofile, smanjujući učinak liječenja.
