Massive Sargassum blooms sweeping across the Caribbean and Atlantic are fueled by a powerful nutrient partnership: phosphorus pulled to the surface by equatorial upwelling and nitrogen supplied by cyanobacteria living directly on the drifting algae. Coral cores reveal that this nutrient engine has intensified over the past decade, perfectly matching surges in Sargassum growth since 2011. By ruling out older theories involving Saharan dust and river runoff, researchers uncovered a climate-driven process that shapes when and where these colossal seaweed mats form.

Almost two out of three corals across popular tourism spots at the world heritage-listed Ningaloo reef have died after an unprecedented marine heatwave hit the Western Australia region, scientists have discovered. The areas in Ningaloo's northern lagoon have undergone a 'profound ecological simplification' with coral species that were keystones to the habitat among those killed

Analysis of new-builds in Birmingham suggests all-electric homes not only use less energy but vary in peak usage
Some of the first homes in the UK designed to meet new building standards put less pressure on the electricity grid than expected, a study has found.
The all-electric properties in Handsworth, Birmingham, have heat pumps, which use electricity to provide heat rather than oil or gas.

Researchers from New Zealand's conservation department conducting an annual grasshopper survey near Lake Tekapo on the South Island have spotted a rare pink grasshopper. The species – the robust grasshopper – is native to New Zealand and is the country’s largest lowland grasshopper. The pink hue is thought to be caused by a genetic mutation, as the insect is typically grey or brown like the river stones of its native habitat in the MacKenzie basin

Analysis published at Cop30 summit shows adhering to pledges offers world hope of avoiding climate breakdown
Sticking to three key climate promises – on renewables, energy efficiency and methane – would avoid nearly 1C of global heating and give the world hope of avoiding climate breakdown, analysis published at the Cop30 climate summit suggests.
Governments have already agreed to triple the amount of renewable energy generated by 2030, double global energy efficiency by then, and make substantial cuts to methane emissions.

The Neoliner Origin set off on its inaugural two-week voyage from France to the US with the aim of revolutionising the notoriously dirty shipping industry
It is 8pm on a Saturday evening and eight of us are sitting at a table onboard a ship, holding on to our plates of spaghetti carbonara as our chairs slide back and forth. Michel Péry, the dinner’s host, downplays the weather as a “tempête de journalistes” – something sailors would not categorise as a storm, but which drama-seeking journalists might refer to as such to entertain their readers.
But after a white-knuckle night in our cabins with winds reaching 74mph or force 12 – officially a hurricane – Péry has to admit it was not just a “journalists’ storm”, but the real deal.

If tropical cyclone Fina crosses the Northern Territory coast on Friday, it could equal the earliest cyclone to make landfall in Australia.
Fina intensified to a category two storm on Wednesday night, the Bureau of Meteorology said, and was moving east about 370km north-east of Darwin before making an expected turn south on Thursday.

The native species is typically grey or brown and the pink hue is thought to be caused by a genetic mutation
An “exceptionally rare” pink grasshopper has been spotted basking in the sun alongside a river in New Zealand’s South Island.
A group of department of conservation researchers were conducting their annual grasshopper survey near Lake Tekapo in the MacKenzie basin when they came across the dark pink female critter.
