But there are alternatives....
Vast swathes of the country’s trees have been killed off by droughts and infestations, in a trend sweeping across Europe. A shift towards more biodiverse cultivation could offer answers
Even the intense green of late spring cannot mask the dead trees in the Harz mountains. Standing upright across the gentle peaks in northern Germany, thousands of skeletal trunks mark the remnants of a once great spruce forest.
Since 2018, the region has been ravaged by a tree-killing bark beetle outbreak, made possible by successive droughts and heatwaves. It has transformed a landscape known for its verdant beauty into one dominated by a sickly grey.

Abernethy Forest, Cairngorms: Thanks to a local collaborative effort, linnets, bramblings, green and goldfinches are coming to this field in joyful flocks
It’s -6C and I’m off to what has been a regular haunt recently – a field planted by Speyside Fields for Wildlife. This is a small, community-run charity that works with local farmers, crofters and others to take over “spare” fields and land for wildlife-friendly crops.
Some sites are planted with annuals such as cornflower, corncockle, marigold and poppy – important sources of pollen, nectar and flowers that used to grow among the grain crops before herbicides became commonplace. Others, such as this one on a hill farm, have been planted with seed crops that benefit birds and other wildlife during autumn and winter.

Study of 1,000 products finds wet, raw and meat-rich products have higher climate impact than dry kibble
Dog food accounts for 1% of the UK’s total greenhouse gas emissions, according to research that found wet, raw and meat-rich products were associated with substantially higher emissions than dry kibble.
The analysis revealed striking differences in the environmental impact of commercial dog foods, with the highest-impact foods being responsible for up to 65 times more emissions than the lowest-rated options.

Shift from ‘big 5’ imports to British fish such as sprats and sardines would help diets and the planet, say researchers
Supermarkets could help to support British consumers to move away from their reliance on mainly imported seafood – the “big 5” of cod, haddock, tuna, salmon and prawns – to more sustainable, nutritious and locally caught fish such as sardines and anchovies, researchers say.
A study by the University of East Anglia (UEA), which confirmed previous research showing consumers did not eat the recommended amount of fish in their diet, suggests the UK could be overlooking a major opportunity to improve national health as well as bolstering local economies by embracing its own rich populations of nutritious small fish.

Scientists also name an overlooked snowdrop growing in the UK and a fruit that tastes like banana and guava
A zombie fungus that springs from a trapdoor and a flame-like shrub named after the fire demon in the Studio Ghibli film Howl’s Moving Castle are among the species of plant and fungi named by scientists in 2025.
A list of 10 “weird and wonderful” new species was compiled by scientists at the Royal Botanic Gardens (RBG), Kew and their international partners, who together named 125 new plants last year. The list also includes an orchid whose flowers look bloodstained and attract sexually aroused flies, and a beautiful snowdrop that had been hiding in plain sight in UK gardens.

Outcome of aggression will determine whether rare earths and other resources drive energy transition – or strengthen US military power and oil interests
The US’s first overt attack on an Amazon nation last weekend is a new phase in its extractivist rivalry with China. The outcome will decide whether the vast mineral wealth of South America is directed towards a 21st-century energy transition or a buildup of military power to defend 20th-century fossil fuel interests.
Although this onslaught was ostensibly aimed at one corrupt dictatorship in a miserably dysfunctional country, the ramifications are far wider.

The practice is ‘much more widespread’ than previously realised, researchers say, with serious environmental impact
The household burning of plastic for heating and cooking is widespread in developing countries, suggests a global study that raises concerns about its health and environmental impacts.
The research, published in the journal Nature Communications, surveyed more than 1,000 respondents across 26 countries.

Sandbanks can shift position during winter storms, but sonar mapping means charts can now be updated immediately
Offshore sandbanks are a particular navigation hazard because, unlike rocks and reefs, they have a habit of shifting position during winter storms.
The Goodwin Sands is a 10-mile (16km) bank off the coast of Deal in Kent, close to the busy shipping lanes of the Dover strait. The sands have claimed about 2,000 vessels over the years. In 1634, two lighthouses were set up on South Foreland for sailors to follow a safe route through.

A year after the Eaton fire, residents returning to Altadena confront lingering contamination and little official clarity
One year on from the Eaton fire, long after the vicious winds that sent embers cascading from the San Gabriel mountains and the flames that swallowed entire streets, a shadow still hangs over Altadena.
Construction on new properties is under way, and families whose homes survived the fire have begun to return. But many are grappling with an urgent question: is it safe to be here?

Across Africa, baobabs have rich symbolic meaning, but the breakneck expansion of the DRC’s capital has reduced their number in the city centre to one
The older inhabitants of Kinshasa can remember when trees shaded its main avenues and thick-trunked baobabs stood in front of government offices.
Jean Mangalibi, 60, from his plant nursery tucked among grey tower blocks, says the capital of the Democratic Republic of the Congo’s frenzied expansion has all but erased its greenery. “We’re destroying the city,” he says, over the sound of drilling from a nearby building site.

Švedski znanstvenici s Karolinska Instituta otkrili su da mikroglija, imunološke stanice živčanog sustava pomažu u zaštiti leđne moždine od oštećenja povezanih sa starenjem. Smatra se, da ovo otkriće može doprinijeti novim spoznajama o nastanku određenih neuroloških bolesti.
Novi dokazi upućuju na to da hvatanje željeza u neupotrebljivim oblicima može izgladnjeti ranjive neurone, što dovodi u pitanje desetljeća razmišljanja o toksičnosti željeza kod Parkinsonove bolesti i otvara nova terapijska pitanja.
Otprilike polovica starijih muškaraca pati od problema sa spavanjem, bolova u leđima ili oboje. Sada je nova studija istražila prethodi li jedno drugom i otkrila da problemi s leđima mogu predvidjeti probleme sa spavanjem godinama kasnije kod muškaraca starijih od 65 godina.
Povećeni omjer neutrofila i limfocita (NLR) značajno je povezan s povećanim rizikom od depresivnog poremećaja i može također korelirati s rizikom od samoubojstva (suicida) među osobama s depresivnim poremećajem, tvrdi nova meta-analiza.
Pokazalo se da genetska mutacija koja se prenosi s majke na djecu u obiteljima pogođenim shizofrenijom sada potpuno utišava moždani receptor koji farmaceutske tvrtke nastoje ciljati novim lijekovima. Naime, promjena jedne aminokiseline transformira receptor 1 povezan s aminom u tragovima (TAAR1) iz funkcionalnog staničnog čuvara u molekularnu slijepu ulicu.
Prema rezultatima nove studije, akupunktura nudi potencijalno niskorizičnu dodatnu opciju za intenzivnu njegu, pomažući u smanjenju ovisnosti o analgeticima i sedativnim lijekovima, skraćenju trajanja mehaničke ventilacije i boravka na intenzivnoj njezi, smanjenju učestalosti delirija te poboljšanju gastrointestinalne pokretljivosti.
Nedavno objavljena studija otkrila je novi mehanizam bakterije Streptococcus anginosus koji potiče rak. Istraživanje pokazuje da metaboliti metionina koje proizvodi ova bakterija mogu značajno doprinijeti razvoju raka želuca. Smatra se, da ovo otkriće produbljuje razumijevanje uloge crijevnog mikrobioma u raku i otvara nove putove za strategije prevencije usmjerene na mikrobiotu.
U novoj studiji kineski znanstvenici su otkrili da nikotinska kiselina - uobičajeni oblik vitamina B3 - može dramatično smanjiti oštećenje jetre uzrokovano ishemijsko-reperfuzijskom ozljedom (IRI), glavnom komplikacijom u kirurgiji i transplantaciji jetre.
Znanstvenici s Princeton University Branch of the Ludwig Institute for Cancer Research identificirali su nove mehanizme kojima metabolički derivat vitamina A all-trans retinoična kiselina, ugrožava i normalan imunološki odgovor tijela protiv raka i, u drugom kontekstu, učinkovitost obećavajućeg tipa cjepiva protiv raka.
Bol u donjem dijelu leđa (LBP) je rašireno stanje povezano s invaliditetom, gubitkom posla i ekonomskim teretom za zdravstvenu skrb. Značajni čimbenici rizika uključuju loš san, fizički i psihički stres, neaktivnost, stariju dob i pušenje. Nova studija je pokazala da osobe s prekomjernom tjelesnom težinom ili pretilošću imaju značajno veći rizik od razvoja boli u donjem dijelu leđa u usporedbi s onima s normalnom tjelesno težinom.
