A Guardian investigation with DeSmog reveals thousands of tonnes of fish are illegally turned into fishmeal and oil off the coast of Guinea-Bissau
The only ice factory on Bubaque, an island in west Africa’s Guinea-Bissau, is out of service. Local fishers, such as Pedro Luis Pereira, are forced to source ice from factories on the mainland, about 70km away – a six-hour round trip by boat.
“The machines have been broken for months,” Pereira says, as he pulls in his nets on the shore of the island inside the protected Bijagós archipelago. “We’ve alerted the ministry of fisheries, but so far, no one has come to fix them.”

Lower Ouseburn, Newcastle upon Tyne: Under boardwalks, in concrete, on window ledges, seeds borne by water and carried on feet survive
The Ouseburn slides glassily, reflecting clouds, as it moves towards the Tyne. These lower reaches are tidal, once used for loading coal barges, here in the industrial heart of Newcastle. From glassworks, bottleworks, potteries and flax mills, the area is now transformed into waterside cafes, bars and housing. The burn flows through a variety of habitats: a wooded dene beneath a soaring viaduct, past stables, a farm and converted factories, exposed mud and ivied ruins, an evolving cityscape, its plants often overlooked.
We study the ground while joggers and prams go past and progress is slow; there’s so much life here in the footpath margins. James Common has researched the city’s plants for six years and his book Urban Flora of Newcastle and North Tyneside is published on Monday. He found the Lower Ouseburn to be the fifth most diverse 1km square of the 188 he covered, the others being nature reserves and the Victorian park of Jesmond Dene. This vibrancy is the result of movement, of people and industry, animals and ships’ ballast, seeds borne by the river or carried on feet.

Private equity group EQT to take 42% stake as supplier faces scrutiny over environmental record and CEO’s pay
A leading European investor will pump fresh funding into Yorkshire Water including helping to cover a £600m loan, despite recent heavy sewage fines and a scandal over executive pay at the utility firm.
EQT, a Swedish private equity group, said on Monday it would take a 42% stake in Kelda Holdings, the Jersey-registered parent company of Yorkshire Water, which has 5.7 million customers across Yorkshire and parts of the East Midlands and Lincolnshire.

Self-styled ‘punk’ beer company bought land in 2020, pledging to plant Scotland’s ‘biggest ever forest’
The self-styled “punk” beer company BrewDog sold its Highland estate for a knockdown price after abandoning its efforts to plant Scotland’s “biggest ever forest” there.
BrewDog’s co-founder James Watt claimed its Lost Forest project at Kinrara in the Cairngorms national park would cover a “staggering area” and capture tens of millions of tonnes of CO2 during its lifetime.

Once abundant in California, the white abalone had all but vanished. Now, thanks to an innovative breeding program, it’s staged a remarkable comeback
On a sunny January afternoon in Bodega Bay, some 70 miles north of San Francisco, the White Abalone Culture Lab is humming with activity.
It’s spawning day. Alyssa Frederick, the lab’s program director, invites me into an industrial room full of troughs and tubs of bubbling seawater. The abalone program is tucked away in the UC Davis Bodega Marine Laboratory, a research facility devoted to studying ocean and coastal health. The goal is to bring the endangered sea snails, known for their iridescent shells and delicate meat, back from the brink.

Prof Tim Lang says country produces far less food than it needs to feed population and is particularly vulnerable
The British government should be stockpiling food, according to a leading expert on food policy, as it is not prepared for climate shocks or wars that could cause the population to starve.
Prof Tim Lang of City St George’s, University of London said the UK produced far less food than it needed to feed itself, and as a small island that relied on a few large companies to feed its giant population, it was particularly vulnerable to shocks.

Plastic, textiles, e-waste and more end up at the vast Dandora site, where waste pickers spend all hours sifting through toxic debris looking for recyclables
On my journey documenting environmental stories in Kenya, I attended the Africa Climate Summit in 2023. It ignited a deeper exploration into the lives of waste pickers, revealing a glaring omission in global recycling narratives: the invisibility of these essential workers.
Living and working in Nairobi, I immersed myself in Dandora, the largest dump in Kenya, spanning more than 12 hectares (30 acres) near the Nairobi River and receiving an estimated 2,000 tonnes of industrial and domestic waste daily. For months I witnessed first-hand how waste is devastating local ecosystems and human lives. Kenya’s waste streams are now overwhelmed by single-use plastics from companies shifting the burden on to informal workers.
Pre-sorting has reduced the amount of recylables in the waste brought by truck to Dandora

zack mennell made a costume out of nappies and waded into filthy waterways saying: ‘I’m going to be the parasite.’ The performance artist’s project became more literal than originally intended
On the Deptford foreshore, a ghoulish figure is sinking into the Thames. Performance artist zack mennell (who writes their name in lower case) wades to their belly button as a crowd watches on. DAs they dip down further, their mutant costume – sewn together from 24 adult nappies – swells with water … and waste.
mennell’s work smears the personal and political across their body. The Thames performance is the finale of a project called (para)site, made in response to revelations of sewage discharge in our waterways and a reaction to the way benefit claimants are labelled a drain on society. “OK,” mennell thought, “I’m going to be the parasite.” Their taking on of pollution was more literal than they intended; they contracted Weil’s disease from rat urine in the water.

When the Gardens of Stone in the Blue Mountains was declared a state conservation area in 2022, it should have been cause of great celebration for Keith Muir. Instead, the plans put forward by the NSW National Parks and Wildlife Service (NPWS) for the nature reserve make him weep.
“The geology is spectacular,” he says of the nature reserve. “The pagoda landforms are sculptured natural artworks, that is the only way to describe them. They are symphonies in stone.”

U novom istraživanju znanstvenici su otkrili potencijalno novu strategiju za borbu protiv Alzheimerove bolesti i Parkinsonove bolesti, stanja koja su povezana s toksičnim nakupljanjem nakupina proteina tau i alfa sinukleina u mozgu. Naime, tubulin, gradivni blok mikrotubula, može spriječiti stvaranje toksičnih nakupina tau i alfa sinukleina i umjesto toga ih usmjeriti u njihove normalne, zdrave uloge.
Japanski znanstvenici otkrili su ključni mehanizam koji omogućuje širenje raka želuca u udaljene organe. Njihova studija pokazuje da stanice raka stimuliraju Wnt signalizaciju u okolnim stromalnim fibroblastima kako bi proizvodile hijaluronan, stvarajući podržavajuće mikrookruženje koje potiče metastaze.
Prirodni nusprodukt metabolizma jetre – ketonsko tijelo, β-hidroksibutirat (BHB) – može ojačati kondiciju i antitumorsku aktivnost CAR T stanica, tvrdi nova studija. Rezultati studije ističu potencijalni novi način poboljšanja imunoterapija raka, naime, pokazalo se da BHB - metabolit koji se proizvodi nakon duljeg posta ili na ketogenoj dijeti - može djelovati kao snažan izvor goriva za T stanice koje se koriste u imunoterapiji. Utvrđeno je da BHB preoblikuje i proizvodnju energije T stanica i regulaciju gena na načine koji poboljšavaju kontrolu tumora u više modela raka.
Nova studija znanstvenika s Wake Forest University School of Medicine identificirala je obećavajuću strategiju za liječenje metastaza u mozgu, jedne od najizazovnijih i najsmrtonosnijih komplikacija raka pluća, melanoma i raka dojke. Naime, metastatska bolest mozga javlja se kod do 30% pacijenata s rakom pluća, melanomom i rakom dojke, a srednje vrijeme preživljavanja ostaje kraće od godinu dana.
Po definiciji, epizodno pamćenje je svjesni fenomen. Tragovi pamćenja koje reaktivira hipokampus i ponovno uspostavi u senzornim korteksima moraju ući u svjesnu svijest da bi se ponovno doživjeli i otvoreno prisjetili. No, sve više dokaza sugerira da se epizodno prisjećanje može dogoditi bez svjesne svijesti, što postavlja temeljno pitanje: kako sjećanja ulaze u svijest?
Kada netko doživi srčani udar (infarkt miokarda), srce se ozlijedi i preoptereti. Čak i kada pacijenti prežive početnu epizodu, srce često s vremenom slabi zbog ožiljaka i gubitka zdravog tkiva. Jedan od prirodnih odgovora tijela je oslobađanje hormona nazvanog ANP (atrijski natriuretski peptid), koji pomaže u smanjenju stresa na srce i može ograničiti dugoročnu štetu. Ali tijelo nažalost proizvodi samo malu količinu ovog hormona, nedovoljnu da napravi veliku razliku u oporavku srca.
Nova studija pruža snažne dokaze o mogućoj učinkovitosti terapija koje ciljaju i lizosome – ili čestice u stanicama koje pomažu u održavanju stanične stabilnosti i dostupnosti hranjivih tvari – i protein nazvan SREBP-1 koji povećava unos glukoze i pomaže tumorima da se odupru trenutnim terapijama koje inhibiraju lizosome, kod karcinoma pluća koji ne reagiraju na imunoterapiju.
Dijabetičke makrovaskularne komplikacije glavni su uzrok smrti i invaliditeta kod dijabetičara, a vaskularna kalcifikacija jedan je od ključnih patoloških mehanizama. Kalcifikacija u aterosklerotskom plaku može uzrokovati ukočenost i smanjenu podložnost vaskularne stijenke te izazvati rupturu aterosklerotskog plaka, što povećava rizik od akutnih kardiovaskularnih događaja.
Upalna osteoliza je stanje koje uključuje progresivno uništavanje koštanog tkiva i opaženo je kod mnogih poznatih skeletnih poremećaja, uključujući reumatoidni artritis, osteoporozu i kronični apikalni parodontitis. Ovo stanje je potaknuto imunosnom hiperaktivacijom, produženim imunološkim odgovorima i povećanim brojem osteoklastnih stanica koje razgrađuju kost, što zajedno uzrokuje upalu i slabljenje zahvaćenog koštanog tkiva.
Osobe koje koriste lijekove s antikolinergičkim učincima, uključujući određene antidepresive, lijekove za urinarnu inkontinenciju i uobičajene antihistaminike, imaju veći rizik od razvoja kardiovaskularnih bolesti, pokazuju rezultati nove studije.
