Exclusive: Sir Paul Marshall’s climate views and those broadcast on GB News said to be ‘in direct opposition’ to those of Church of England
The co-owner of GB News, a British TV channel accused of broadcasting climate change denial, has donated £28m to influential Church of England institutions that support climate action.
This raises “serious questions”, say Christian leaders, given that Sir Paul Marshall’s views on the climate crisis and those frequently broadcast on the TV channel are “in direct opposition” to the Church of England, which believes that “responding to the climate crisis is an essential part of our responsibility to safeguard God’s creation and achieve a just world”.

The species is abundant within the protected archipelago but when they migrate outside the marine reserve to give birth they run the gauntlet of industrial fishing
The unmistakable fluted T-shape of a scalloped hammerhead shark slides by, followed by a diver holding his breath and a metal spear like an extra-long snooker cue. The spear hits the fish behind its dorsal fin and the 2-metre shark darts away, disgruntled but otherwise unharmed.
Carlos Robalino, a marine biologist from the Galápagos Islands, trained as a shark researcher in Mexico but is now back home and working as a junior researcher at the Charles Darwin Foundation. When we meet in March, he is one of the divers on the foundation’s research expedition to Darwin and Wolf, the most northerly islands in the Galápagos marine reserve.

Third of world’s energy needs should come from electricity by 2035, says Murat Kurum, as priorities set out for this year’s UN climate summit
The world should aim to meet a third of its energy needs from electricity within a decade to cut greenhouse gas emissions, the host of the next UN climate summit has said.
While about a third of global electricity generation already comes from renewable sources, other energy-intensive sectors – chiefly transport, heating and industries – have lagged behind. Close to four-fifths of final energy still comes from fossil fuels, as a result.

JPMorgan Chase leads 65 banks making decisions incompatible with restraining rising temperatures, researchers say
The world’s largest banks committed $906bn in financing to the fossil fuel industry last year, an “unfathomable” increase in investment locking in years more of coal, oil and gas production as the world continues to overheat, a new report has found.
The surge in new fossil fuel lending, up $64bn or nearly 8% on 2024, shows that the world’s largest 65 banks are making decisions incompatible with international agreements to restrain rising global temperatures, according to the coalition of environmental groups behind the new analysis.

The bottom of the ocean has barely been explored, but every journey to the deep reveals wondrous new lifeforms. As underwater mining gains momentum, we risk destroying one of the Earth’s last great wildernesses
On 8 March 2014, at 1.20am, Malaysian Airlines flight 370 veered off its scheduled route from Kuala Lumpur to Beijing. An hour later, military radar spotted the plane heading west over the Andaman Sea. Six or seven hours later, it is presumed to have crashed somewhere over the southern Indian Ocean, one of the least studied bodies of water in the world.
Just how little we knew about this part of the ocean became clear during the subsequent search for the missing aircraft. Before a proper underwater search could even begin, a vast stretch of seafloor had to be mapped. Over the next three years, a team of ships from Australia, China and Malaysia scanned the bottom with a combination of submersible robots and ship-borne sonar. Together, they charted a swath of ocean roughly 1,500 miles long and 150 miles wide, encompassing an area the size of France. The maps produced from these scans revealed a lost world, full of undersea canyons, crevasses, volcanic plateaux and a single, enormous cliff taller than the Swiss Alps. Even the abyssal plains, thought to be some of the flattest areas on the planet, were home to previously uncharted hills.

Brigg, Lincolnshire: With harvest approaching, we’re putting the glorious long evenings to good use, and both humans and insects are working hard to protect the crops
There’s something magical about the long evenings in June, the warmth and the way the setting sun casts long shadows across the fields. The extra hours are much-needed though as there is plenty to do.
We’re in the run-up to harvest in July, so if the weather is dry we walk up and down the seed crop tramlines, pulling out (rouging) unwanted wild oats, brome and blackgrass. They drop seeds that could contaminate not only our ground, but potentially someone else’s. Strict numbers govern how many of such plants are allowed per hectare in a seed crop, and independent inspectors check the results. Government officials in the Animal and Plant Health Agency will even walk the higher quality seed crops.

Global effort needed to limit effects of pollution, industrial fishing and climate crisis, World Ocean Assessment says
The world’s oceans are under “severe and accelerating” pressure from human activities, with the rate of sea-level rise double that of a decade ago, according to a damning assessment from the United Nations.
The “intensifying” stressors, which include pollution and large-scale industrial fishing, are cumulative, said the report, resulting in widespread biodiversity loss and putting ocean systems under “severe strain”.

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.

Marine biologist Issah Seidu has found a way for Ghana’s fishing communities to earn a living – and help protect the ancient and critically endangered fish species
Guitarfish are an odd-looking and ancient species, with the tail of a shark and the flattened body of a ray, but their coveted fins have driven populations to the brink of extinction. In west Africa, where their meat is also a local delicacy, many guitarfish species are among the most critically endangered fish in the ocean.
Conservationists at the International Union for the Conservation of Nature (IUCN) describe the slow-maturing ray, which produce young annually, as an “indicator species”, which reflect the overall health of an ecosystem and pose challenges in the way coastal fishing of them is managed. The IUCN red list categorises more than half of guitarfish species as critically endangered.

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.
Moždani udar je razorno stanje koje remeti pravilnu funkciju mozga. Nakon moždanog udara, mnogi pacijenti obično će osjetiti bol u udovima na strani tijela suprotnoj od moždane lezije. U rijetkim slučajevima, bol se razvija i na istoj strani kao i lezija, šireći se bilateralno na zrcalni način. To je fenomen poznat kao bilateralna bol ili bol zrcalne slike.
U nedavno objavljenoj studiji znanstvenici su istraživali može li istovremena inhibicija homologa Kirstenovog virusnog onkogena štakorskog sarkoma (KRAS), receptora epidermalnog faktora rasta (EGFR) i pretvarača signala i aktivatora transkripcije 3 (STAT3) izazvati trajnu regresiju karcinoma gušterače i spriječiti otpornost na liječenje.
