An experiment designed to investigate the role lobsters play in regulating sea urchin numbers unexpectedly found sharks were eating them instead. The research, led by the University of Newcastle marine ecologist Jeremy Day, involved 50 long-spined and 50 short-spined sea urchins tethered to the entrance of a lobster den on the south coast of NSW. Over the course of 25 nights, sharks ate 45 of the urchins, while lobsters ate only four. Sea urchins are native to NSW but have become are a pest in Tasmania, where they are threatening local ecosystems

The stars of 367 Collins Street have welcomed baby birds to the nest. Two hungry chicks are taking meals after entering the world on a Melbourne skyscraper. Last year’s eggs were unable to hatch after the mother stopped incubating – likely due to a territorial dispute – making the stakes all the higher this year

Interdisciplinary marine research is pivotal for addressing ocean sustainability challenges but may exclude diverse socio-economic, cultural, or identity groups. Drawing on perspectives of marine Early Career Researchers, we highlight the importance of Diversity, Equity, and Inclusion (DEI) in advancing interdisciplinary marine science and present ten recommendations to enhance DEI. As our ocean faces increasing threats, fostering DEI within this domain is not merely an aspirational goal but an ethical imperative.

New fuel efficiency standards due to come into force from January will not apply to at least four large vehicle models because of a gap within the legislation, the motor industry has been told.
The Albanese government said earlier this year its new vehicle efficiency standards (NVES) would save motorists about $1,000 a year while cutting fuel use and carbon emissions.

Investment will fund two CCS clusters – but environmental campaigners have criticised plans
What is carbon capture, usage and storage?
Rachel Reeves is paving the way for a multibillion-pound increase in public-sector investment at the budget after the government announced plans to commit almost £22bn over 25 years to fund carbon capture and storage projects.
In what is expected to be one of the biggest green spending promises of the parliament, the chancellor, prime minister and the energy secretary, Ed Miliband, will unveil the details on a visit to the Liverpool city region on Friday declaring a “new era” for clean energy jobs.

The extinction of hundreds of bird species caused by humans over the last 130,000 years has led to substantial reductions in avian functional diversity -- a measure of the range of different roles and functions that birds undertake within the environment -- and resulted in the loss of approximately 3 billion years of unique evolutionary history, according to a new study.

Harris reiterates she won’t ban fracking if elected as Trump runs ads stating the opposite in tight Pennsylvania race
Kamala Harris reiterated that she won’t ban fracking on Wednesday in an interview with KDKA-TV, the CBS affiliate in Pittsburgh, Pennsylvania. Though the US vice-president once backed a ban on the fuel extraction process, she said on Wednesday that she changed her mind since joining Joe Biden’s presidential campaign in 2020 and has since remained firm.
The statement comes as she and Donald Trump compete for votes in Pennsylvania, a swing state with 20 seats in the electoral college and a major gas producer. The Trump campaign, meanwhile, has been running ads claiming that if elected, Harris would enshrine a ban on fracking, costing Pennsylvania over 300,000 jobs.

Laborers from the Caribbean nation pick berries and process Thanksgiving turkeys across rural America
On a foggy morning in June 2021, I left my Durham, North Carolina, home to travel two and a half hours to rural Whiteville, North Carolina, population 5,000-ish. I headed there to meet some of the town’s newest, albeit temporary, residents: 200 Haitian migrants employed as blueberry pickers.
These farm workers put food on our tables – and on family tables back in Haiti. But they’re a less visible work force in our food supply chain, toiling largely out of sight on farms in places like Columbus county, with its miles of fields. They are doubly invisible among US guest workers, who overwhelmingly hail from Mexico.

Sea levels along the US coastline could rise as much as 12in from 2020 to 2050 due to climate crisis, scientists warn
Floods affecting much of the south-east US show the destructive force of higher sea levels and warmer temperatures. Now, researchers at the non-profit Climate Central are using artificial intelligence to predict how climate-related flooding will affect US communities into the next 75 years if warming continues at its current pace.
Previous research has shown that by 2050, sea levels along the US coastline could rise as much as 12in (30cm) from 2020 levels. High-tide flooding, which can occur even in sunny weather, is projected to triple by 2050, and so-called 100-year floods may soon become annual occurrences in New England.
