Scientists say yields from crops fertilised with recycled human waste rival those produced by organic methods

Using fertilisers derived from human faeces and urine can be as productive as conventional organic ones, with no risk of transmitting disease, according to new research.

It may seem unappetising, but humans have been using human waste as a fertiliser for thousands of years because it contains the key nutrients that plants need to grow, including nitrogen, phosphorus and potassium. Ploughing human excrement – conventionally flushed down our toilets and into the sewage system – back into the soil creates a more sustainable farming system without significant drops in yield, the researchers found.

In relationships, controlling and coercive behaviour is now a criminal offence. In British politics, it is glorified

Don’t let them talk to you about freedom. This government is stripping out fundamental liberties with the speed and determination you would expect in the aftermath of a military coup. Knowing that their days in office are numbered, the Conservatives seem to be snuffing out democracy as quickly as they can.

Even before the latest amendment, the public order bill was the most repressive legislation of the modern era, potentially criminalising all meaningful protest. If Rishi Sunak’s new proposal is passed, protests can be stopped before they begin on the grounds that they might be “disruptive”. Disruptive protest was redefined by last year’s Police Act to include noise. Now the definition is being further extended to incorporate “slow marching”. This Minority Report amendment puts us on the wrong side of the law before we even raise our hands in objection.

Automatic warning system activated to issue flood alerts during industrial action by staff on Wednesday

Flood-prone areas in England will be relying on automated back-up systems for flood alerts and warnings on Wednesday, as Environment Agency (EA) workers strike over pay.

Systems that would normally be monitored by experienced staff, some of whom have been left relying on food banks as a result of the cost of living crisis, will be put on autopilot during the industrial action, after weeks of working to rule failed to bring the government to the negotiating table.

The United Arab Emirates (UAE)’s Abu Dhabi National Oil Company (ADNOC) has signed two deals, one involving a pilot project to mineralise CO2 in rock formations, and the other to create new markets for hydrogen and promote global clean energy value chains, at Abu Dhabi Sustainability Week, the Gulf state's national oil company announced on Tuesday.

High court in Japan agreed defendants could not have predicted the massive tsunami that crippled the power plant and triggered a nuclear meltdown

Three former executives from the company that operates the wrecked Fukushima Daiichi nuclear plant have had their not-guilty verdicts upheld by a court in Japan, dealing a blow to campaigners demanding the firm take legal responsibility for the disaster in March 2011.

The Tokyo high court on Wednesday cleared Tsunehisa Katsumata, the former chairman of Tokyo Electric Power (Tepco), along with former vice-presidents Ichiro Takekuro and Sakae Muto, of professional negligence resulting in death.

Study also says eating one serving of fish with PFAS could be equivalent to drinking contaminated water every day for a month

Wild caught, freshwater fish in the United States are far more contaminated with toxic PFAS “forever chemicals” than those commercially caught in oceans, and the highest levels are found in fish from the Great Lakes, a new analysis of federal data suggests.

The peer-reviewed study by public health advocate Environmental Working Group (EWG) also found eating one serving of US freshwater fish contaminated with median PFAS levels could be equivalent to drinking highly contaminated water every day for a month.

The fact the eastern bristlebird had not been seen nor heard in south-east Queensland since its Gondwana rainforest home was ravaged in the black summer bushfires of 2019/20 was, in some ways, unsurprising.

For one, there are thought to have been fewer than 40 individual birds in its northern population.

Our national research on bushfires since 2003 means we know much more about how they behave – and Australians are safer for it

It has been 20 years to the day since bushfires burst out of the Brindabella Ranges and into the suburbs of our nation’s bush capital. Four lives were lost, many people were injured and more than 500 homes were destroyed.

There had been big bushfires before, and there were bigger bushfires to come, but the tragic day in Canberra of 18 January 2003 marked a pivotal moment in Australian bushfire science.
