But there are alternatives....
More than 20,000 votes cast in Butterfly Conservation’s poll of 60 native species to find nation’s favourite for first time
The votes are in on Britain’s favourite butterfly, and it is one of the most ubiquitous yet spectacular backyard beauties that has flown to victory.
With its lavender, yellow and maroon eye spots and luscious rusty red and black colouration, the peacock butterfly is both beautiful and commonplace, flying throughout spring, summer and autumn in all corners of the British Isles.

Imperial College scientists analysed health records before and after introduction of air pollution reduction zones
Low emission and clean air zones attract controversy whenever they are proposed, but there is growing evidence that they work in improving air quality. The Bradford zone was followed by a reduction of about 25% in GP visits for heart and breathing problems and survey data shows that the central London zone was followed by a reduction in the likelihood of a person taking sick leave.
Now analysis of health records has found emergency admissions to hospital reduced after the introduction of the T-charge and ultra-low emissions zone (Ulez) in central London.

Long-awaited course to examine human effects on natural world and explore everyday ways to aid biodiversity
School pupils will learn how to plant a wildflower-friendly garden, according to long-awaited plans announced on Thursday for a natural history GCSE in England, Wales and Northern Ireland.
Campaigners have for more than a decade called for the study of biodiversity loss and global heating to be introduced as a dedicated subject in classrooms across the country, but despite a curriculum being previously drawn up, its launch has faced repeated delays.

Intricate tests show hair-trigger detection causes cells on outer surface of leaf to soften, prompting closure
The Venus flytrap is one of nature’s most impressive predators, luring insects with the intoxicating scent of nectar before capturing them with a snap of its jaw-like leaves.
Now, scientists have revealed the mechanism that allows the carnivorous plant to react with lightning speed, resolving a problem that stumped Charles Darwin and many researchers after him.

Darwin and Wolf Islands in the Galápagos archipelago are the kinds of places scuba divers and marine biologists dream of visiting, myself included. I even wrote a children’s book imagining a team of scientists exploring the underwater wonders of the Galápagos islands on a beautiful sailing ship.
That’s why I’m still pinching myself that earlier this year I got to take part in a real expedition to Darwin and Wolf.

Cardiff: I still remember my first otter sighting, on a bog in the mid-90s. This, in a lab on a stainless steel table, is something else
Otter No 4,888 was found at the side of the road near the River Cefni on Anglesey in November 2024. The collector froze her body and sent it, as every dead otter in the UK should be, to Cardiff University’s Otter Project for a postmortem. The vast majority of the 200 or so animals dissected here annually are roadkill.
On one of the hottest days of the year, we put on lab coats, gloves and masks. Otter No 4,888 is laid out on the stainless steel table. Aside from a mark on her hind left leg and some bleeding from the nose, this young female’s body looks intact. I take the rare opportunity to look closely at her cat-like whiskers, the white patch under her chin, and the round black pads of her webbed feet.

As the US shuts its doors to most refugees, there’s little hope of a new system to help those forced from home by climate impacts
Millions of people around the world are having their lives upended by floods, storms and heatwaves worsened by the climate crisis. Those forced to flee their home countries, however, are finding that the door to the US is more firmly shut than ever.
Neither US nor international law recognizes environmental hazards, such as climate-related displacement, as a valid cause to claim asylum or gain entry through other migration pathways, despite the mounting toll of disasters caused by an overheating planet.

US energy secretary Chris Wright featured in seminars to judges when he was a fracking executive
As cities and states sue big oil for billions in damages over allegations that it covered up the dangers of its products, rightwing organizations are attempting to discredit the wave of litigation. They claim the lawyers behind it are teaming up with an environmentally focused legal education non-profit to bias federal judges against oil companies.
But it is actually fossil fuel-backed organizations that are attempting to sway the judiciary in their favor, one of those law firms is countering. Evidence of this includes judicial seminars hosted by one such group featuring pro-industry speakers such as the current energy secretary, Chris Wright, in his former occupation as a fracking executive.

Pacoima is hemmed in by highways and heavy industry, and its residents are fighting pollution with hyperlocal air quality monitoring
Jose Luis Salas looks up at the ladder. “Are you ready?” he asks Shance Taylor, an environmental project manager who’s holding a white container, about the size of a shoebox, covered with wires and numbers.
Taylor nods and climbs up to reach the side of Salas’s tidy house in Pacoima, a neighborhood in Los Angeles’s north-east San Fernando valley. The curious box in their hands is known as Aeroqual sensor – part of a community air-quality monitoring program run by Pacoima Beautiful, a local environmental group.

Brojne vrste kardiovaskularnih bolesti i faktori rizika za kardiovaskularne bolesti povezani su s većim rizikom od Alzheimerove bolesti, pri čemu nizak krvni tlak pokazuje najjaču vezu, tvrdi nova studija.
U jednoj od najvećih studija do danas, znanstvenici su ispitali odnos između dugotrajne izloženosti onečišćenju zraka i koronarne ateroskleroze te otkrili da je čak i na umjerenim razinama dugotrajna izloženost onečišćenju zraka povezana s uznapredovalijom koronarnom bolešću srca.
Nova studija povezuje kronični zatvor (konstipacija) s većom vjerojatnošću depresije, ukazujući na puteve crijevo-mozak i potrebu za zajedničkom procjenom crijevnog i mentalnog zdravlja. Depresija je među najraširenijim, onesposobljavajućim mentalnim poremećajima u svijetu, značajno doprinoseći teretu bolesti i smrtnosti. Prema nedavnim globalnim procjenama, oko 350 milijuna ljudi ima depresiju. Kronični zatvor jedan je od najčešćih gastrointestinalnih poremećaja i uzrokuje trajnu nelagodu, remeti svakodnevne aktivnosti i psihološku dobrobit.
Rezultati nove studije pokazuju da povećanje histaminergičke signalizacije može izoštriti pronalaženje pamćenja, podržati adaptivno donošenje odluka i stabilizirati učenje iz negativnih iskustava, otkrivajući zanemarenu ulogu neurotransmitera u kognitivnim procesima.
Kineski znanstvenici razvili su mineralizirani DNK hidrogel koji kombinira imunološku regulaciju s održivom regeneracijom kostiju. Koristeći tetraedarske DNK nanostrukture i mineralizaciju kalcijevog fosfata, znanstvenici su stvorili skelet koji potiče aktivnost makrofaga pogodnu za zacjeljivanje, a istovremeno podržava matične stanice koje stvaraju kosti.
Prema rezultatima nove studije, rizik od moždanog udara se ne povećava jednako kod svih pacijentica s atrijskom fibrilacijom. Naime, studija sugerira da je ženski spol više poput modifikatora rizika, s povećanim rizikom od moždanog udara koji se prvenstveno opaža kod žena u dobi od 75 i više godina ili onih s većim opterećenjem drugim zdravstvenim stanjima.
Trenutne terapije za reumatoidni artritis oslanjaju se na trajnu imunosupresiju, a ne na obnovu imunološke tolerancije, pri čemu remisija bez lijekova ostaje rijetka. No, nedavna izvješća sugeriraju da bi terapija himernim antigenskim receptorom T (CAR-T) stanicama usmjerenim na CD19 mogla biti učinkovit pristup.
Pacijenti s refluksom kiseline, koji se javlja kada želučana kiselina prolazi u jednjak, dobro poznaju simptome: žgaravicu, podrigivanje, bol u prsima i probleme s gutanjem. Osim ovih tegoba, refluks kiseline također povećava rizik od raka jednjaka, koji ima petogodišnju stopu preživljavanja od oko 22%.
Rana primjena paracetamola može ubrzati zatvaranje otvorenog ductus arteriosusa kod izrazite nedonoščadi, tvrdi nova studija. Otvoreni ductus arteriosus (PDA) je često stanje kod nedonoščadi kod kojeg se fetalna krvna žila između aorte i plućne arterije ne zatvara normalno nakon rođenja. Stanje može povećati rizik od ozbiljnih bolesti i smrtnosti, posebno među najmanjom nedonoščadi.
Nova studija pokazuje potencijal novog pristupa liječenju anoreksije nervoze - poremećaja za koji su učinkoviti tretmani značajno ograničeni. Naime, pokazalo se, da je ketogena nutritivna intervencija - dijeta s visokim udjelom masti, niskim udjelom ugljikohidrata i umjerenim udjelom proteina - bila izvediva i sigurna za pacijente s anoreksijom nervoze s normaliziranom težinom i blago pothranjenom težinom. Sudionici studije su dobro podnijeli ketogenu intervenciju, s visokim stopama pridržavanja i bez značajnog gubitka težine tijekom cijelog programa.
