The US, Russia, Iran and Saudi Arabia – some of the highest oil-producing nations and major greenhouse gas emitters – opposed the measure
The UN has voted 141-8 to adopt a resolution backing a world court opinion that countries have a legal obligation to address climate change, with the US – which is the world’s biggest historical emitter – among the small group opposing it.
The UN secretary general, António Guterres, said Wednesday’s general assembly vote, in which 28 countries abstained, underscored that governments are responsible for protecting citizens from the “escalating climate crisis”.

Phenomenon, often seen around Britain’s coast at this time of year, is caused by a combination of algae and weather
At this time of year a sinister-looking substance can often be sighted around Britain’s coast: a frothy foam piled up along the shoreline or appearing in long ribbons offshore. People sometimes assume this foam is the result of pollution or sewage dumping. In fact it is a common natural phenomenon produced by a combination of algae and weather.
Sea algae start to grow in April as conditions warm. The most common sort, phaeocystis, is not toxic and forms part of the marine food chain. When the algal bloom dies it leaves a brown scum of organic material with surfactant properties, which, like soap, lowers the surface tension of the water.

Willington, County Durham: On a fine May morning, there’s no better time to look at the stunning array of ways that bees and flowers have co-evolved to interact
“It is a truth universally acknowledged, that a wild flower in possession of a fortune in nectar and pollen, must be in want of a pollinator,” Jane Austen might have written, had she been a botanist. All along this former railway line, on a sunny May morning, there are thousands of newly opened flowers laden with such inducements, vying for the attention of foraging bumblebees. And none delivers its pollen with such deception and violence as broom (Cytisus scoparius).
A large bumblebee arrives, settles briefly, finds no nectar and departs, leaving a deranged tangle of stamens protruding from the petals. What happened? Poking my finger into an intact flower, to mimic the visitor, there’s an explosion of pollen as 10 stamens and a coiled stigma, confined in the boat-shaped keel petal, break free. Simultaneously, they deliver and collect pollen, with a gut-punch to the insect’s furry abdomen. Bumblebees don’t seem to mind; the trap has been tripped in almost every flower on this bush.

Environmental activists lock themselves to pesticide barrels in protest outside Syngenta headquarters
More than 40 people, including Greenpeace UK’s programme director, Amy Cameron, have been arrested after a protest outside pesticide company Syngenta’s Yorkshire headquarters.
A number of the activists locked themselves on to 15 blue pesticide barrels outside the headquarters, blocking the gates and leading to the temporary closure of the local A62. Activists had transformed a roundabout outside the front entrance into a giant hazard symbol carrying the message “Syngenta poisons nature” with an arrow pointing directly at the building. The action took place on World Bee day.

Global study finds wrappers, bottles and lids on shorelines of 93% of countries analysed as UN talks to tackle issue in turmoil
Plastic food wrappers, bottles, lids and caps are by far the most common items of litter found on the world’s shorelines, a study has found.
Researchers looked at data from more than 5,300 surveys of coastal litter to produce the first global analysis of its kind. They found the data in 355 existing studies on the subject.

Landmark report calls for widespread air conditioning and says UK temperatures forecast to exceed 40C by 2050
British homes will need air conditioning to survive predicted levels of global heating, the government’s climate advisers have warned in a report, as measures such as drawing curtains, opening windows and growing trees for shade are not likely to be enough.
Air conditioning should be installed in all care homes and hospitals within the next 10 years, and in all schools within 25 years, according to the Climate Change Committee (CCC), which published a major report on adapting to the impacts of global heating on Wednesday.

As conflict in Iran sends prices soaring, fossil fuel companies are seeing extraordinary gains – but the crisis may also accelerate the shift towards clean energy

A friend of mine was recently left in tears after filling up the car she relies on to drive to work. Thanks to the US-Israeli attacks on Iran, prices at the pumps have soared. She wasn’t sure how her family was going to make it to the next paycheck.
It is a personal story and a distressing one, but the big picture is truly obscene. Fossil fuel companies are raking in monstrous, unearned war profits taken from the pockets of people like you, me, my friend, and any of us who fills up a vehicle or pays an energy bill.

One way to pay for wildlife conservation is to allow the rich to bag a few animals for high prices. But critics see this approach as an exercise in neocolonialism

When pupils could no longer play outside, St John’s school in Barnet decided to act, enlisting Trees for Cities to help rethink its outside space
The play area at St John’s Church of England primary in Barnet, north London, used to flood so severely it was often unusable. “It would get so bad that the children couldn’t be dismissed from the playground,” says Macci Dobie, the school’s headteacher. “We had to dismiss them from different parts of the school or, literally, parents were stepping into puddles to lift their children out of the classroom.”
Because the school sits in a basin with clay foundations, rain would pool on the grey tarmac and just sit there, often denying the children a proper break for play outside.

Gestacijski dijabetes snažan je faktor rizika za budući dijabetes tipa 2, čak i kod žena s normalnom tjelesnom težinom prije trudnoće, tvrdi nova studija. Stoga stručnjacii pozivaju na ranije testiranje i bolje praćenje.
Konzumiranje hrane koja sadrži uobičajene aditive za konzervanse u hrani može povećati rizik od visokog krvnog tlaka (hipertenzija) i kardiovaskularnih bolesti, prema rezultatima novog istraživanja.
Prestanak pušenja može biti povezan sa smanjenim rizikom od demencije, posebno za ljude koji izbjegavaju veće debljanje nakon prestanka pušenja, tvrdi nova studija.
Migrena s aurom povezana je s povećanim rizikom od ishemijskog moždanog udara kod osoba srednje i starije dobi, pokazuje nova studija. Migrena bez aure nije bila povezana s povećanim rizikom. Studija ne dokazuje da migrena s aurom uzrokuje povećani rizik od moždanog udara, već samo pokazuje povezanost.
Izgleda da osobe s hepatičkom steatozom, obično nazvanom bolest masne jetre, imaju veću količinu nekalcificiranog, rupturirajuće koronarnog plaka i suočavaju se s gotovo dvostruko većom stopom kardiovaskularnih događaja poput srčanog udara u usporedbi s onima bez steatoze, pokazuje nova studija.
Nova studija je pokazala da kada je vitamin C prisutan i u hrani, poput lisnatog povrća poput špinata, može smanjiti rizik od raka. Studija također sugerira da uzimanje dodataka vitamina C nakon svakog obroka može imati umjeren pozitivan učinak u smanjenju stvaranja nitrozacijskih produkata povezanih s rizikom od raka od nitrita i nitrata u prehrani, poput onih koji se nalaze u hrani poput slanine i salame.
Nedostatak vitamina D povezan je s umjerenijom do jakom boli nakon operacije raka dojke i povećanom konzumacijom opioidnih lijekova, otkriva novo istraživanje. Stoga pacijentice s rakom dojke s niskom razinom vitamina D (ispod 30 nmol/L) mogu imati koristi od uzimanja dodataka prehrani prije radikalne mastektomije.
Znanstvenici sa Stanford Medicine otkrili su da najčešće bijele krvne stanice u našem tijelu - imunološke stanice zvane neutrofili - mogu proizvoditi protein C4A za koji nitko nije znao da ga proizvode. Novo uočena neutrofilna veza, kao izvor proteina zvanog C4A, povezuje dugi popis drugih opažanja koja su identificirala C4A kao izražen faktor rizika za shizofreniju. Osobe sa shizofrenijom imaju tendenciju povećanja broja neutrofila u krvi, a najučinkovitiji lijek za shizofreniju inhibira neutrofile.
Nedavna studija pokazuje da poremećaji spavanja tijekom trudnoće mogu biti značajan faktor rizika za gestacijski dijabetes. Inače, gestacijski dijabetes je brzo rastući javnozdravstveni problem koji povećava rizik od komplikacija i za majku i za dijete tijekom trudnoće, a dugoročno i rizik od pretilosti i dijabetesa.
Lijek tezepelumab pokazao se učinkovitim u kliničkim ispitivanjima kod osoba s teškom astmom. Naime, tezepelumab je bio povezan s boljim ishodima kod pušača, pacijenata s preklapajućom astmom i kroničnom opstruktivnom plućnom bolesti (KOPB), kao i kod adolescenata.
