Scientists have warned of a potential “regime shift” in the oceans, as the rapid growth of huge mats of seaweed appears to be driven by global heating and excessive enrichment of waters from farming runoff and other pollutants.
Over the past two decades, seaweed blooms have expanded by a staggering 13.4% a year in the tropical Atlantic and western Pacific, with the most dramatic increases occurring after 2008, according to researchers at the University of South Florida.

Trust had $254m invested in companies such as Chevron, BP and Shell in 2024, a nine-year record, analysis shows
The Gates Foundation Trust holds hundreds of millions of dollars in fossil fuel extractors despite Bill Gates’ claims of divestment made in 2019.
End-of-year filings reveal that in 2024 the trust invested $254m in companies that extract fossil fuels such as Chevron, BP and Shell. This was a nine-year record and up 21% from 2016, Guardian analysis found. Adjusting for inflation, it was the highest amount since 2019.

Experts call for tighter regulation as GPS tracking reveals how people’s behaviour affects the lives of some of the world’s largest birds
Many people look up to admire the silhouette of raptors, some of the planet’s largest birds, soaring through seemingly empty skies. But increasingly, research shows us that this fascination runs both ways. From high above, these birds are watching us too.
Thanks to the development of tiny GPS tracking devices attached to their bodies, researchers are getting millions of data points on the day-to-day lives of these apex predators of the skies, giving us greater insight into where they hunt and rest, and how they die.

There are so many koalas in some places that food is the issue – while elsewhere populations are threatened by habitat loss. And there are no easy fixes
On French Island in Victoria’s Western Port Bay, koalas are dropping from trees. Eucalypts have been eaten bare by the marsupials, with local reports of some found starving and dead. Multiple koalas – usually solitary animals – can often be seen on a single gum.
Koalas were first introduced to French Island from the mainland in the 1880s, a move that protected the species from extinction in the decades they were extensively hunted for their pelts. In the absence of predators and diseases such as chlamydia, the population thrived.

Fears of storm surges and flooding, with landslides and volcanic mudflows possible on Luzon
The Philippines is experiencing its first tropical storm of the year. Ada, also known as Nokaen, slowly developed into a tropical storm on Friday, travelling northwards along the east coast over the weekend and bringing torrential rain of up to 200mm a day and maximum wind gusts of up to 65mph near the storm’s centre.
The system is expected to remain a tropical storm until Tuesday as it tracks north-west, though weakening as a result of the incoming north-east monsoon, transitioning back to a tropical depression, which could bring further rain and strong winds enhanced by the monsoon later in the week.

Frome, Somerset: Get tuned in to the river’s sounds and you’re treated to a symphony of noise, from susurrating hisses to great belches
After three decades living alongside mute waterways in East Anglia, with their soundless glide over clay, I am learning a liquid language here, and all its boulder dialects, as our winter‑filled local stream gushes down its limestone gorge.
My fellow country diarist and wild swimmer Amy-Jane Beer shares my passion for river music. She tells me of her compulsion to listen when fresh water is given a voice by coming to the surface.

Food produce and other waste has been littering Sussex coastline as capsized shipping containers wash ashore
Coral Evans was walking along the beach in Brighton on Tuesday evening when she came across an unfamiliar sight.
“Hundreds of dust masks had washed up, along with single-use plastic gloves and cans of dried milk,” she said. “It was odd to see in winter – because nothing surprises us in summertime with the amount of people on the beach.”

A return to nuclear power is at the heart of Japan’s energy policy but, in the wake of the 2011 disaster, residents’ fears about tsunamis, earthquakes and evacuation plans remain
The activity around the Kashiwazaki-Kariwa nuclear power plant is reaching its peak: workers remove earth to expand the width of a main road, while lorries arrive at its heavily guarded entrance. A long perimeter fence is lined with countless coils of razor wire, and in a layby, a police patrol car monitors visitors to the beach – one of the few locations with a clear view of the reactors, framed by a snowy Mount Yoneyama.
When all seven of its reactors are working, Kashiwazaki-Kariwa generates 8.2 gigawatts of electricity, enough to power millions of households. Occupying 4.2 sq km of land in Niigata prefecture on the Japan Sea coast, it is the biggest nuclear power plant in the world.

Pioneering scheme hopes species that thrived for thousands of years in Irish waters can do so again
The dinghy slowed to a stop at a long line of black bobbing baskets and David Lawlor reached out to inspect the first one.
Inside lay 60 oysters, all with their shells closed, shielding the life within. “They look great,” beamed Lawlor. So did their neighbours in the next basket and the ones after that, all down the line of 300 baskets, totalling 18,000 oysters.

Some regions of the continent have enough ice to push up sea levels by 15 metres if they all melt, but researchers don’t yet fully understand the consequences
On one side of Dr Ben Galton-Fenzi’s view across the vast Totten ice shelf, the sun sat low on the Antarctic horizon. On the other, a full moon.
The ice shelf is “flat and white”, says Galton-Fenzi. “If there’s cloud around, you lose the horizon.”

Izgleda da pravilno pripremljeni proizvodi od bambusa mogu ponuditi nekoliko zdravstvenih prednosti, uključujući poboljšane probavne, antioksidativne i metaboličke ishode, pokazao je pregled više studija. Ovi učinci vjerojatno su povezani s bogatim sadržajem dijetalnih vlakana, bioaktivnih spojeva i mikronutrijenata u bambusu.
Desetljeća duga studija pokazuje kako obrasci u cirkulirajućim metabolitima, oblikovani genima i načinom života, mogu identificirati ljude s visokim rizikom od dijabetesa tipa 2 mnogo prije pojave simptoma.
Američki znanstvenici s University of Virginia School of Medicine otkrili su kako popularna ketogena dijeta s niskim udjelom ugljikohidrata štiti od epileptičnih napadaja i moguće neurodegenerativnih bolesti poput Alzheimerove i Parkinsonove bolesti.
Rezultati nove studije pokazuju da promjene metilacije DNK specifične za dob u spermi u područjima kontrole otiska mogu doprinijeti riziku od poremećaja iz autističnog spektra kod potomstva. Smatra se, da su ovi rezultati relevantni jer su dijagnoze autizma porasle dok mnogi muškarci kasnije u životu postaju očevi.
Od svih vrsta raka dojke, trostruko negativni rak dojke (TNBC) je najagresivniji i nedostaju mu specifične terapije. TNBC također ima veću vjerojatnost metastaziranja, odnosno putovanja kroz krvotok kako bi se proširio na druge organe, što uzrokuje većinu smrtnih slučajeva povezanih s rakom dojke svake godine. Do sada je praćenje cirkulirajućih tumorskih stanica (CTC), snažnog pokazatelja metastaza raka, bilo izazovno jer postoji vrlo malo markera koji specifično identificiraju te stanice.
Prema rezultatima novog istraživanja, eksperimentalno cjepivo protiv raka, NOUS-209, sigurno stimulira imunološki sustav da cilja prekancerozne i kancerogene stanice kod osoba s Lynchovim sindromom (LS).
Nove procjene otkrivaju povijesne dobitke u preživljavanju od raka i milijune spriječenih smrtnih slučajeva, istovremeno otkrivajući velike nejednakosti i upozoravajući da bi današnje političke odluke mogle odrediti hoće li se napredak nastaviti ili će stagnirati.
Novi biomarker u krvi odražava opseg ozljede mozga nakon ishemijskog moždanog udara i može predvidjeti ishode za pacijente mjesecima do godinama kasnije, tvrdi nova studija.
Trudnice s upalnom bolešću crijeva (IBD) imaju više razine proupalnih imunoloških molekula, poznatih kao citokini, u vaginalnoj sluznici nego njihove zdrave vršnjakinje, pokazala je nova studija.
Znanstvenici su identificirali bradikardiju - abnormalno nizak broj otkucaja srca - kao simptom predoziranja ksilazinom. Ovo revolucionarno otkriće Icahn School of Medicine at Mount Sinai moglo bi pomoći liječnicima hitne medicine da otkriju jesu li pacijenti bili izloženi ksilazinu, lijeku koji se sve češće nalazi kao dodatak ilegalnoj ponudi fentanila.
