Exclusive: Fighting Dirty taking legal action against government over proposal it says could import weaker standards
An environmental campaign group is taking legal action against the government over proposals that it claims could fast-track chemical hazard classifications from other countries with lower standards into UK law.
Fighting Dirty claims proposals to change the classification and labelling of potentially hazardous chemicals could result in the UK weakening standards on cancer-causing substances.

Photosynthesis does not always result in wood growth, a key factor in carbon dioxide sequestration
Trees may not be able to store as much planet-heating carbon as hoped, a study suggests, with researchers finding photosynthesis does not always lead to wood growth.
Scientists studied 137 sites across the US and found trees stopped growing months before the point in the year at which photosynthesis stopped.

ExclusiveA vast area of the Bellingshausen Sea should be covered by sea ice by now, with one expert calling the loss of ice ‘depressing’
Antarctica’s west coast is missing an area of winter sea ice the size of France, sparking concerns for threatened penguins other marine life and global sea levels.
One expert said the loss of ice in the Bellingshausen Sea was “depressing” and the failure of ice to form could have intensified a heatwave over the continent’s peninsula last week that saw daytime temperatures peak at 15.4C which is more than 20C above average.

Appearance of a western reef heron in north Wales is unlikely to be the last, as heating temperatures mean species can survive Britain’s winter, say experts
It is a tropical bird typically encountered between west Africa and India, but last week a western reef heron arrived in north Wales in what is believed to be the first ever sighting in the UK.
The heron was first spotted in Foryd Bay at the weekend before flying to nearby Caernarfon harbour where it fed among the boats.

Wolsingham, Weardale: These stunning butterflies are here in incredible numbers this year, yet what’s most remarkable is their multigenerational migration
There’s a painted lady basking on the footpath. Her orange, black-tipped, white-spotted wings, a little worn after her long journey, blend with shadows and sun-flecks on heatwave-baked mud, so she’s almost under our feet before she takes flight. And here’s another, nectaring on a dandelion; and another; then several more. I can’t recall ever seeing so many so early in the year.
Waiting for the arrival of these migrant butterflies is akin to anticipating the first swallow. Tantalising mid-April sightings from Wales and Cumbria were reported on social media, but we waited until mid-May before finding our first in Weardale.

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.

Despite plunging border crossings, the Trump administration is circumventing laws to expedite building in a vast, pristine wilderness
The Trump administration has waived a slew of environmental and historical preservation laws that would allow it to build a towering border wall that cuts through Big Bend national park, a vast protected wilderness in south Texas.
Congress poured a whopping $46.5bn for border wall construction into the “Big, Beautiful” bill last year, supercharging Donald Trump’s ambition to wall off the southern border with Mexico. The longest unwalled stretches lie along a roughly 500-mile (800km) section of west Texas that Customs and Border Protection calls the “Big Bend sector”.

While La Calera faced severe water rationing, local springs were being drained by the drinks giant’s franchise. So the residents fought back
When a severe drought struck La Calera near Bogotá, many of its residents lost their water for drinking, cooking and farming and faced up to 15 days of strict water rationing each month. Yet the area is home to Chingaza reservoir, which supplies about 70% of the drinking water for Colombia’s capital.
As the drought stretched from April 2024 to April last year, people began to look more closely at how their water was being managed.

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.

Enterobaktin, molekula koju proizvode crijevne bakterije, možda ima iznenađujući ključ za smanjenje crijevne upale, pokazuje nova studija. Ne izravnim napadom na imunološki sustav, već privremenim usporavanjem vlastite proizvodnje energije stanica.
Neočekivano laboratorijsko opažanje dovelo je tim znanstvenika do otkrića kako prehrana može utjecati na preživljavanje u životinjskim modelima glioma, jednog od najagresivnijih i najsmrtonosnijih oblika raka mozga. Naime, otkrilo se kako ograničavanje jednog nutrijenta, aminokiseline metionina, u prehrani destabilizira organizaciju DNK i dovodi do smrti stanica raka i povećanog preživljavanja životinja.
Japanska studija provedena na 2.044 starije odrasle osobe otkrila je da oni s nižim razinama vitamina C u krvnoj plazmi imaju tendenciju imati manji volumen sive tvari u mozgu, kao i nižu povezanost među skupom moždanih regija poznatih kao mreža zadanog načina rada.
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.
