Four-year study warns destabilised marine food webs could jeopardise food security by 2050
Warming seas around the UK and the wider north-east Atlantic could destabilise marine food webs, weaken ocean health and jeopardise food security by 2050, according to a four-year study.
Scientists who projected the impact of climate breakdown on four key groups of marine life crucial to maintaining ocean ecosystems in the region said their results challenged assumptions that in middle latitudes, such as the UK, marine biodiversity was likely to increase across the board.

With parts of region served by company in severe drought still, regulators give it six weeks to come up with action plan
Repeated failures by South West Water to tackle leaks are putting customers at higher risks of losing water supplies as parts of the region remain in severe drought, regulators have said.
In a warning to the privatised company that serves 1.8 million people across the south-west of England, the regulators said it had been failing to meet targets to reduce leaks and repair burst pipes for seven years.

A stricken container ship shed tonnes of tiny pellets called nurdles on the west coast. Five years on, locals are counting the cost to marine life and livelihoods
On the beach in Pamunugama, on Sri Lanka’s west coast, women in uniform work under the scorching sun. They sift through rubbish washed ashore, searching among the usual litter for something much smaller: tiny plastic pellets.
Five years ago, in May 2021, this same beach was swamped with pellets as smoke rose over the Indian Ocean.

Events that deliver about half of global rainfall are getting shorter but more intense, with wide-ranging implications
The world’s wettest rainstorms produce about half of the global annual rainfall. Now a study shows that these intense downpours have become shorter in duration and fewer in number, compressing the same amount of rain into quicker and more extreme events, with implications for flood and drought risk.
Chiyuan Miao and colleagues from Beijing Normal University in China analysed daily measurements between 1980 and 2022 from more than 19,000 rain gauges around the world. They found that an average of about half of the world’s rainfall fell during about nine multi-day storms, delivered over a cumulative time of about 28 days.

We were promised a panacea for the climate crisis and a way to save our food system. So why is nobody firing up the chicken vats? I went to find out
On 5 August 2013, a man and a woman ate a burger. Not just any burger: a world-historic burger, made from cattle cells grown in a laboratory by Mark Post, a professor of vascular physiology at Maastricht University in the Netherlands. The burger had taken two years to produce and cost €250,000 (about £210,000 at the time), money furnished by the Google co-founder Sergey Brin. Now it was being tasted in public for the first time at Riverside Studios in London, at an event attended by 200 members of the press and livestreamed to thousands.
To make this particular burger, Post had extracted stem cells from the shoulder muscle of a living cow, then cultivated them in plastic containers filled with a nutrient-rich supplement called foetal bovine serum, which is derived from cow foetuses. The cells eventually became 20,000 strands of tissue, which in turn became a single 140g patty. Post believed that beef produced this way had the potential to dramatically reduce greenhouse-gas emissions and slow the climate crisis. Raising cattle for consumption requires massive amounts of land and water – and massive amounts of feed grown at a high environmental cost. He projected that global demand for meat would soon outstrip our ability to produce it the old-fashioned way, at which point our food systems would become unsustainable. But that didn’t have to mean a mass recalibration of our consumption habits or a global shift away from red meat. Post and his team had found another way.

Liverpool: Their summer flowers provide the name and the fame, but this species is arguably at its best now
Beech mast crunches underfoot, and the occasional conker catches the sunlight, tiny beacons leading me to Camp Hill, south Liverpool, with its distant views over the Mersey estuary. Goldfinches erupt from desiccated knapweed, and a flock of pink-footed geese fly overhead. For once, the birds are not my goal, but a tree: the tulip tree (Liriodendron tulipifera).
Every autumn, the Camp Hill tulip tree flaunts its flamboyant presence: the Lady Gaga of the parkland. Named because its flowers resemble a tulip flower, and its leaves a tulip silhouette, few can resist its tulle lace canopy of butter-gold leaves. The luminescence is enhanced by the sheen of its leaf cuticles, and the fissured trunk adds yet more sensory impact. Yet this year there is a strangeness: instead of the golden monotone you would expect of this moment, there is a messy mix of different shades. Might the summer drought have disrupted the pigment battle between anthocyanins and carotenoids?

Ministers urged to go further than proposed cut to 110 decibels to ease acute stress on birds and other animals
Campaigners are calling on the UK government to protect the welfare of wild animals by cutting the maximum noise level of fireworks sold to the public from 120 to 90 decibels.
The Center for Wild Animal Welfare (CWAW) has said lowering the limit to 90dB – which is about one-eighth of the loudness of 120dB – would help to protect millions of wild animals from acute stress by reducing the area over which a firework disturbs surrounding wildlife.

From energy prices to datacenters, climate became a cost-of-living issue – and a winning one
Climate-forward Democrats swept into power on Tuesday night as a blue tsunami flipped the Senate, House and several governor’s races. Voters were laser-focused on affordability, and experts said Democrats succeeded in linking cost-of-living concerns with rising energy prices, datacenters and, to some extent, the climate crisis. They may have even created a path for a “new climate politics”.
The results delivered a sharp rebuke of Donald Trump, who started a war with Iran that raised gas pump prices across the country and exposed the fragility of fossil fuels, all while the US oil industry earned $130bn in profits since the war began. Household energy costs soared, driven by various factors including constraints on renewables, climate disasters and a datacenter boom.

The BLVD is home to 250 enterprises, from banks, tattoo shops and restaurants to museums and a performing arts centre
Passing through the Mojave desert on State Route 14, going by landscapes Hollywood uses to represent alien planets, a driver might not expect to find a walkable, tree-lined boulevard.
But there are nine beautiful, leafy blocks on West Lancaster Boulevard, a piece of what used to be Highway 14. They were redeveloped as part of a mixed-use urban streetscape in the city of Lancaster, California in 2010.
The BLVD, as it’s been rebranded, is home to 250 public and private enterprises, from banks, tattoo shops and restaurants to museums, a performing arts centre and a public library. City Hall is just a block south.
The city invested $11.5m (£8.5m) to transform a busy thoroughfare into an inviting public space. The three lanes in the centre of the former five-lane road were replaced by a series of tree-lined ramblas – Spanish for “avenue” and “watercourse,” because dry stream beds served as streets in early cities.
The redesign was planned and funded by the city of redevelopment agency. Within four years of completion, it had generated more than $270m in economic output, attracted $130m in investment, created hundreds of jobs and prompted the building or renovation of hundreds of housing units, according to the city.
The revitalisation has also created more intangible benefits, residents say. The city centre the feels like a gathering space, they said — somewhere where they can feel like part of a community.

Terapija kombinacijom triju lijekova može preoblikovati tumorsko mikrookruženje u bolesnika s uznapredovalim rakom želuca te pokazuje obećavajući sigurnosni profil, ukazuju rezultati nove studije. Ova studija pruža detaljan uvid u to kako navedeni lijekovi preoblikuju imunološke stanice u neposrednoj blizini tumora te otkrivaju obećavajuće ciljeve za buduće imunoterapijske pristupe.
Vizualne abnormalnosti nakon upotrebe psihodelika desetljećima se prepoznaju kao poremećaj perzistentne percepcije halucinogena (HPPD), ali ovo stanje se ne dijagnosticira često jer zahtijeva klinički značajnu nelagodu i oštećenje. Najčešća nuspojava nakon primjene psihodelika su svjetlije boje.
Žene s nasljednim stanjem kolesterola, obiteljskom hiperkolesterolemijom, mogu imati nešto veći rizik od razvoja preeklampsije, stanja u trudnoći koje može uzrokovati ozbiljne komplikacije, pokazuje nova studija.
Antihipertenzivni lijekovi se široko propisuju, ali kliničke značajke i genetska predispozicija koja je u osnovi oštećenja jetre koje povremeno uzrokuju ostaju slabo shvaćene.
Imunološki sustav posjeduje snažne stanice koje mogu prepoznati i uništiti rak, no ta sposobnost može postupno slabjeti kada se te stanice nalaze unutar tumora. No, znanstvenici s Medicinskog fakulteta Yong Loo Lin pri Nacionalnom sveučilištu u Singapuru (NUS Medicine) identificirali su protein koji bi mogao pomoći u održavanju aktivnosti tih imunoloških stanica koje se bore protiv raka, te potencijalno ponuditi novi način za jačanje terapija modificiranim T-stanicama u borbi protiv raka debelog crijeva.
Kliničko ispitivanje u trajanju od 16 tjedana otkriva potencijalno korisne promjene u inzulinskim odgovorima u regijama mozga povezanim s pamćenjem, nakon svakodnevne konzumacije neslanog, pečenog kikirikija, nudeći nove tragove o tome kako prehrana može utjecati na kognitivno zdravlje.
Nova studija provedena u SAD-u rasvjetljava ulogu majčinog mlijeka u poticanju razvoja crijeva i sprječavanju hiperbilirubinemije – stanja u kojem se bilirubin, otpadni produkt razgradnje crvenih krvnih stanica, nakuplja u krvi i uzrokuje žutu boju kože i očiju, poznatu kao žutica.
Slušne halucinacije – ili slušanje glasova koje drugi ne čuju – pogađaju više od 70% osoba sa shizofrenijom. Unatoč liječenju antipsihoticima, otprilike 40% i dalje ima trajne halucinacije. Za ove pacijente hitno su potrebni novi pristupi liječenju.
Nova studija je otkrila da žene koje su češće jele hranu s visokim udjelom šećera imaju veći rizik od raka dojke, dok ni ukupni šećer u prehrani ni konzumacija voća nisu pokazali statistički značajnu povezanost. Voće je činilo oko 43% ukupnog šećera u prehrani, a prosječni unos šećera bio je 44 grama dnevno. Žene koje su konzumirale više od dvije porcije hrane s visokim udjelom šećera tjedno imale su 28% veći rizik od onih koje su jele jednu porciju mjesečno ili manje.
Protein koji sudjeluje u izgradnji zuba mogao bi se jednog dana koristiti kako bi se oštećenim zubima omogućilo da se sami obnove, pokazuju rezultati nove studije provedene u SAD-u.
