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.

Activists argue business model is ‘plantation tourism’ designed to benefit elite and disadvantage most Jamaicans
Devon Taylor remembers when the Mammee Bay shoreline in St Ann, Jamaica, was filled with children frolicking in the ocean after school, fishers haggling with locals over the price of their daily catch and craft vendors carving souvenirs under almond trees.
“I grew up on Mammee Bay,” Taylor says. He recalls fetching seawater in bottles for his grandmother when she was no longer able to go to the beach, learning to swim in the shallows, and watching generations of fishers cast their nets. “That beach raised us. It fed us.”

Rebalance Earth is investing in Broughton Sanctuary to generate financial, environmental and social returns
From a high point on the hill, the North Yorkshire landscape unrolls below. The moorland above gives way to grassland, trees and then pasture, divided by the region’s traditional dry stone walls.
The view may be idyllic, but it belies the condition of parts of this land, belonging to the sprawling 1,100 hectare (2,500-acre) Broughton Sanctuary estate, near Skipton.

It could top 90F in several cities hosting World Cup games – and workers could pay the price with their health
As the World Cup kicks off, labor advocates and scholars warn that the workers making the tournament possible could face serious heat-related risks.
“It’s going to be extremely hot, and you just cannot leave people unprotected or you’re going to deal with a lot of injuries,” said Jonathan Alingu, co-executive director of Central Florida Jobs With Justice, which has been calling for worker protections at the Miami games. “Or, God forbid, something even worse.”

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.
