Butterfly Conservation poll is open until 7 June with choice of 60 species from small tortoiseshells to purple emperors
Will it be the rapidly disappearing former garden favourite, the small tortoiseshell? Or the poet John Masefield’s “oakwood haunting thing”, the charismatic purple emperor? Or perhaps the brimstone, the ultimate harbinger of spring?
The question of which is Britain’s favourite butterfly is being put to a popular vote for the first time. The charity Butterfly Conservation is running the poll, which runs until 7 June, giving people the chance to choose their favourite from the 60 species that fly around Britain every summer.

Timmy the whale is lost at sea, presumed dead.
In normal circumstances, the loss of a young humpback whale would be a sad yet unremarkable part of the circle of life. Dead whales help sustain thousands of marine species – and are part of the global carbon cycle.

Glenn Murcutt pioneered architecture that was sensitive to its environment, and accomodating to changing temperatures and wildlife
The house teaches you things, Lynne Eastaway says. Today, a choir of cicadas fill the scrub with a rhythm that rises and falls. On other days, there may be visits from birds, goannas, echidnas, wombats, wallabies and kangaroos.
“The bush ends, and the house begins,” she says. “You’re not the centre; you’re just part of it. That’s the thing you learn.

Murlough Nature Reserve, Dundrum, County Down: Its arrival signals the start of summer, and another cycle of its extraordinary breeding method
Sheltered from the Irish Sea by the towering white foredunes of Murlough beach, I follow a trail through the heather and scrub. In the distance, the Mourne mountains slip in and out of view, already charred by this year’s wildfires. My attention turns to the season’s happier signs: sand martins chittering overhead; the scratchy cries of a whitethroat deep in the gorse; a meadow pipit stuttering into song flight. And now, the chant that clinches summer’s arrival.
I follow the cuckoo’s call and find him perched in a stunted sycamore. Through binoculars, I meet his orange eye. As he leans into his song, his jaunty tail and drooping wings make a fin for the long torpedo of his body – the ideal form for a life lived on the move.

When the birds started nesting on her land at Useless Bay, Chile, Cecilia Durán Gafo decided she would protect them from people and predators
Five pairs of rubbery feet carry velvet-sheathed black-and-white bodies towards the rope line separating the king penguins from the dozen or so visitors, who look on in awe. As these emissaries shuffle over, a hundred of their cohorts parade on a nearby bank, splashing around in the water and regurgitating food into their chicks’ open beaks.
The king penguin (Aptenodytes patagonicus)makes its home almost exclusively on islands in the Southern Ocean. But it has been coming to this wind-battered bay in southern Chile’s Tierra del Fuego region for hundreds of years, probably because its shallow shores offer protection from marine predators and humans.

Study of samples from seven winters suggests neurotoxic metal coming from wood itself rather than old paint
Wood heating is reintroducing lead into the air of local communities and homes, a systematic investigation by academics has found.
Overwhelming evidence of lead’s neurotoxicity meant the metal was banned as an additive in petrol more than 25 years ago. The research by academics from the University of Massachusetts Amherst began by analysing samples of particle pollution from five suburban and rural towns in the north-east US. They looked for tiny particles of potassium that are given off when wood is burned and also particles containing lead.

Ever fancied creating your own enormous effigy? One Cornish art collective has reinvigorated the practice – and now they want to draw on the public’s skills, too
This New Year’s Eve, environmentalist and author Lisa Schneidau did something she had never done before. She welcomed in 2026 with giants. “At a certain time of the evening, they started appearing from all over the town. Then everyone flooded out of their houses and congregated into a massive procession of giants and lights and drums and music. It was absolutely extraordinary.”
Schneidau’s fairytale experience happened in Lostwithiel, the Cornish home town of the art collective The Lost Giants (TLG), a group of craftspeople and artists reviving the British tradition of making giants and beasties and goliaths. The giants she celebrated with were made of wooden frames and cloth, papier-mache and card, but were full of life.

A warm spell mitigated some of the effects of the strike but colder weather would have taken their own toll
May 1926 is remembered in Britain for the general strike, when the TUC called out millions of workers in support of miners who had been locked out while fighting a pay cut.
The strike, which lasted from 3 May to 12 May, took place during a spell of relatively mild weather with little rain. Transport was disrupted but fine conditions allowed many people to walk or cycle to work. There was a shortage of coal but this was mitigated because there was less need for heating. The TUC, fearing legal action and doubting the strike could be sustained, called it off after nine days.

Osobe s Parkinsonovom bolešću mogle bi pronaći olakšanje zahvaljujući novoj tehnici duboke stimulacije mozga koja ne zahtijeva operaciju, pokazuje nova studija. Jedan od najučinkovitijih tretmana za uznapredovalu Parkinsonovu bolest uključuje operaciju implantacije elektroda u mozak, koje isporučuju električne impulse za stimulaciju moždanih regija. No, znanstvenici su sada razvili tehniku koja bi mogla primijeniti istu stimulaciju izvan lubanje, bez potrebe za operacijom mozga.
Rezultati nove studije pokazali su da je kombinacija kolbopasvira i sofosbuvira vrlo učinkovita i sigurna u liječenju kroničnog hepatitisa C, uključujući genotip 3b i pacijente s kompenziranom cirozom jetre ili koinfekcijom hepatitis B virusom (HBV), te se smatra vrijednom opcijom za eliminaciju hepatitis C virusa (HCV).
Analiza bioloških satova u ljudskom tijelu sugerira da premalo sati sna - i previše - može ubrzati starenje mozga, srca, pluća i imunološkog sustava te je povezano sa širokim rasponom bolesti.
Nova studija pokazala je da je biološka dob starija od kronološke dobi povezana s većom vjerojatnošću razvoja demencije, i to posebno vaskularne demencije, te s ranijom dobi početka bolesti kod svih podtipova demencije.
Osteoporoza, koja je vrlo česta kod žena u postmenopauzi, dugo se povezivala s povećanim rizikom od prijeloma. Nova studija sugerira da također može povećati ukupni rizik od smrti kod žena - za čak 47% - posebno unutar specifičnih raspona gustoće minerala kostiju (0,46-0,71 g/cm2 za ukupnu gustoću minerala bedrene kosti).
Izgleda da antitijelo NG101 može potaknuti regeneraciju oštećenog tkiva leđne moždine, pokazuje nova studija provedena u Švicarskoj. Naime, uz poticaj ovog novog antitijela, nova živčana vlakna ponovno formiraju funkcionalne veze, omogućujući pacijentima da postanu samostalniji.
Izraelski znanstvenici su identificirali prethodno neprepoznati obrambeni mehanizam u crijevima, pokazujući da crijevne matične stanice mogu aktivno reagirati na infekciju salmonelom i pomoći u zaštiti crijeva od bakterijske invazije.
Iako dijele slične depresivne i kognitivne simptome, biološki temelji bipolarnog poremećaja i velikog depresivnog poremećaja su različiti. Nova studija, prva je koja identificira klinički relevantne putove koji povezuju metaboličku disfunkciju, strukturu mozga i kogniciju kod poremećaja raspoloženja, s jačim i specifičnijim učincima uočenim kod bipolarnog poremećaja. Ističe potencijal ciljanja metaboličkih putova za poboljšanje kognitivnih simptoma kod bipolarnog poremećaja.
Izgleda da mentalni stres može izravno utjecati na protok krvi u mišićima i finu motoričku kontrolu tijekom jednostavnih fizičkih zadataka, pokazuje nova studija. Naime, stabilnost sile tijekom kontrakcija vrlo niskog intenziteta i vaskularni odgovori uključeni u izvođenje motoričkih zadataka mogu se smanjiti pod kognitivnim stresom.
Znanstvenicii koji prate pacijente s blagim moždanim udarom otkrili su da je abnormalno širenje i iskrivljenje moždanih arterija, a ne tradicionalno sužavanje velikih arterija, najsnažnije povezano s progresivnim oštećenjem mozga malih krvnih žila i lakunarnim moždanim udarom.
