But there are alternatives....
Doyne Farmer says a super-simulator of the global economy would accelerate the transition to a green, clean world
It’s a mind-blowing idea: an economic model of the world in which every company is individually represented, making realistic decisions that change as the economy changes. From this astonishing complexity would emerge forecasts of unprecedented clarity. These would be transformative: no more flying blind into global financial crashes, no more climate policies that fail to shift the dial.
This super simulator could be built for what Prof Doyne Farmer calls the bargain price of $100m, thanks to advances in complexity science and computing power.

The government has not made enough of a dent in emissions, but global trends and a shambolic opposition offer a rare opportunity to act

There is good news out there, even if it feels like scraps in a world on the brink. Some came last week – with plenty of caveats – when analysts at the Paris-based International Energy Agency (IEA) found coal-fired power generation decreased in both China and India last year.
This is a potentially big shift. Among other things, it exposes the hollowness of arguments in Australia that there is no point doing anything about the climate crisis because the big Asian economies are building endless new coal plants.

Torcross, Devon: 2026 has been defined by storms here. My job of repairing a thatched roof is simple compared with the wider recovery
During the storm, the waves sounded like bombs going off under the house, Bonni Breeze Lincoln tells me. She lives on the seafront of Torcross, a Devon village that is accustomed to weathering storms, but even she is not used to waves shattering her storm shutters, or sending seawater down the chimney.
I’ve come to Torcross to repair the thatch on Bonni’s roof. Up the ladder, I tie bundles of reed, called “wads”, to pack them into the holes; the thatch is riddled with shingle, fragments of seaweed and even limpet shells. Looking down the seafront to torn up paving slabs and slate roofs that yawn open to the sky, it’s clear that this house – the oldest in the village – has come off comparatively well. The soft, springy nature of thatch allows it to absorb even the impact of breaking waves.

Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware
The world is closer than thought to a “point of no return” after which runaway global heating cannot be stopped, scientists have said.
Continued global heating could trigger climate tipping points, leading to a cascade of further tipping points and feedback loops, they said. This would lock the world into a new and hellish “hothouse Earth” climate far worse than the 2-3C temperature rise the world is on track to reach. The climate would also be very different to the benign conditions of the past 11,000 years, during which the whole of human civilisation developed.

The radical project is an attempt to preserve wildlife in one of Europe’s most light-polluted countries, but can they persuade local people they will still feel safe?
Two yellowing street lamps cast a pool of light on the dark road winding into the woods outside Mazée village. This scene is typical for narrow countryside roads in Wallonia in the south of Belgium. “Having lights here is logical,” says André Detournay, 77, who has lived in the village for four decades. “I walk here with my dog and it makes me feel safe and gives me some protection from theft.”
Belgium glows like a Christmas decoration at night, as witnessed from space. It is one of the most light-polluted countries in Europe, with the Milky Way scarcely visible except in the most remote areas.

Born of student disquiet after the 2008 crash, the group says it is reshaping economists’ education
As the fallout from the 2008 global financial crash reverberated around the world, a group of students at Harvard University in the US walked out of their introductory economics class complaining it was teaching a “specific and limited view” that perpetuated “a problematic and inefficient system of economic inequality”.
A few weeks later, on the other side of the Atlantic, economics students at Manchester University in the UK, unhappy that the rigid mathematical formulas they were being taught in the classroom bore little relation to the tumultuous economic fallout they were living through, set up a “post-crash economics society”.

Vast flocks of birds return to Somerset and a rare grebe turns an ordinary walk into something special
After weeks of heavy rain, Cheddar reservoir in Somerset is finally full again – of water, and of birds. Thousands of coots, hundreds of gulls and ducks, and dozens of great crested grebes crowd the surface, some already moulting into their smart breeding plumage, crests and all.
They feed almost constantly, building up energy reserves for the breeding season. Among the throng are some less familiar visitors: a flock of scaup, the males bulkier than the nearby tufted ducks, with pale grey backs that catch the light. Flocks of goosanders dive frequently for food, the colourful males looking like a cormorant in extravagant drag.

Marineland Antibes, the French government and animal welfare groups all agree on the need to rehome the listless killer whales but no one can agree where
In a sprawling aquarium complex in south-eastern France that once drew half a million visitors a year, only a few dozen people now move between pools that contain the last remaining marine mammals of Marineland Antibes. Weeds grow on walkways, the stands are empty and algae grows in the pools, giving the water a greenish hue.
It is here that Wikie and Keijo, a mother and son pair of orcas, are floating. They were born in these pools, and for decades they performed in shows for crowds. But since the park’s closure in January 2025, they no longer have an audience. When they are alone, they “log”, or float at the water’s surface, according to a court-ordered report released last April.

Intricate ice formations can grow on frozen lakes and seas when relatively warm ice is exposed to still air
Intricate fern-like “frost flowers”, said to be painted on windows and windscreens by Jack Frost, are a familiar feature of British winter. In Arctic regions there is an even prettier three-dimensional version.
These frost flowers are typically 3-4cm across and whole gardens of them grow on frozen lakes and seas. Like the window version, they are the result of ice crystals growing in a slow, orderly fashion.

Emissions have plunged 75% since communist times in the birthplace of big oil – but for some the transition has been brutal
Once the frozen fields outside Bucharest have thawed, workers will assemble the largest solar farm in Europe: one million photovoltaic panels backed by batteries to power homes after sunset. But the 760MW project in southern Romania will not hold the title for long. In the north-west, authorities have approved a bigger plant that will boast a capacity of 1GW.
The sun-lit plots of silicon and glass will join a slew of projects that have rendered the Romanian economy unrecognisable from its polluted state when communism ended. They include an onshore windfarm near the Black Sea that for several years was Europe’s biggest, a nuclear power plant by the Danube whose lifetime is being extended by 30 years, and a fast-spreading patchwork of solar panels topping homes and shops across the country.

Pretilost doprinosi otprilike 1 od svaka 4 smrtna slučaja od zaraznih bolesti u SAD-u, procjenjuje se u novoj velikoj studiji. Naime, osobe s pretilošću imaju veći rizik od hospitalizacije ili smrti od zaraznih bolesti, od gripe i COVID-19 do gastroenteritisa i infekcija mokraćnog sustava.
Propisivanje acetilsalicilatne kiseline prilikom prvog prenatalnog pregleda svim trudnicama povezano je s ukupnim smanjenjem razvoja teške preeklampsije, pokazuju rezultati nove studije. Preeklampsija je ozbiljna komplikacija trudnoće koja uključuje trajno visoki krvni tlak i znakove oštećenja organa poput proteina u mokraći ili abnormalnosti jetre.
Znanstvenici sa Case Western Reserve University napravili su značajan napredak u razumijevanju Barrettovog jednjaka, prekanceroznog stanja koje dramatično povećava rizik od razvoja adenokarcinoma jednjaka, jednog od najbrže širećih i najsmrtonosnijih oblika raka.
Posljednjih godina mnogi medijski izvještaji i utjecajni ljudi na društvenim mrežama naglašavali su opasnosti od konzumiranja previše ugljikohidrata. Iako prehrana bogata ugljikohidratima može biti štetna, konzumiranje previše masti može uzrokovati više zdravstvenih problema, tvrdi nova studija.
Dijabetes tipa 2 i visoki krvni tlak (hipertenzija) dijele genetsku vezu, pokazuje novo istraživanje. Naime, ljudi s jednim stanjem imaju veću vjerojatnost da će razviti drugo stanje.
Znanstvenici sa Åbo Akademi Universityi identificirali su novu molekularnu promjenu kod pacijenata s rakom debelog crijeva i razvili genetski model bolesti koji stvara tumore u debelom crijevu, slične onima koji se vide kod pacijenata. Ovaj novi model pomaže znanstvenicima da bolje razumiju kako se bolest razvija i podržava potragu za novim tretmanima.
Nova studija upozorava da dugotrajna primjena inhibitora protonske pumpe (PPI) može oštetiti apsorpciju hranjivih tvari. Inhibitori protonske pumpe su klasa lijekova koja uključuje lijekove poput omeprazola, pantoprazola, rabeprazola, lansoprazola i esomeprazola. Koriste se za liječenje želučanih poremećaja. Njihova neprimjerena primjena dulje od preporučenih od strane liječnika može uzrokovati nutritivne nedostatke, poput anemije, i ugroziti zdravlje kostiju.
Rezultati nove studije otkrivaju kako imunološke stanice u mozgu odraslih osoba mogu regulirati stvaranje novih neurona. Ovo otkriće vodi do novog razumijevanja kako imunološke stanice mogu utjecati na neurogenezu odraslih, proces stvaranja novih neurona u mozgu. Neuroni su temeljni prijenosnici informacija u mozgu, a imunološke stanice provode nadzor i šalju poruke novim neuronima.
Prema rezultatima nove studije, izgleda da vremenski ograničeno hranjenje - oblik povremenog posta - značajno smanjuje simptomatsku aktivnost bolesti i sustavnu upalu kod odraslih s Crohnovom bolešću i prekomjernom tjelesnom težinom ili pretilošću. Ovo je prva studija koja pokazuje da jedenje samo unutar 8-satnog prozora može smanjiti aktivnost Crohnove bolesti za 40% i nelagodu u trbuhu za 50% u samo 12 tjedana, u usporedbi sa standardnim rasporedom prehrane.
Skupina lijekova koji se često koriste za liječenje dijabetesa također može pomoći u zaštiti bubrega koji stare, tvrdi nova studija. Naime, nedavno objavljena studija je testirala lijekove nazvane SGLT2 inhibitori kod afričke tirkizne killifish, male ribe koja živi samo 4 do 6 mjeseci. Budući da ribe tako brzo stare, znanstvenici su mogli promatrati ekvivalent desetljeća starenja organa u samo nekoliko tjedana. Rezultati su pokazali da ribe kojima su davani spomenuti lijekovi imaju zdravije bubrege kako stare.
