An international court has ruled that nations have a legal obligation to reduce greenhouse gas emissions to protect the marine environment, marking a significant legal milestone. The International Tribunal for the Law of the Sea, meeting in Hamburg, Germany, declared that the ocean absorbing planet-warming gases constitutes marine pollution. The tribunal also emphasized that wealthier nations must cut emissions more rapidly than developing ones. This is the first time an international court has made such a ruling, signaling a growing role for legal institutions in addressing climate change. Meanwhile, in South Korea, a historic legal case involving over 200 individuals, including 60 children, is being heard against the government for its inaction on climate change. A decision is expected later this year, and Amnesty International Korea suggests it could establish a human rights precedent. In the UK, wind power has for the first time supplied the majority of the country’s electricity over the course of a full year. According to data from Imperial College London, wind generated 32% of the UK’s electricity, surpassing gas, which contributed 31%. Strong winds and new offshore wind farms, such as the Dogger Bank A in the North Sea, played a key role in this shift. Additionally, imported wind power from Denmark via a new undersea cable and imported nuclear power from France contributed to the change. Dan McGrail, chief executive of RenewableUK, said the UK has crossed a threshold in moving from gas to wind power, with clean energy now dominating the electricity system. Scientists have developed a method to keep human breast tissue viable outside the body for at least a week, which is considered a major breakthrough. By culturing tissue samples in a special gel solution, researchers can test various drugs and hormones on live tissue, which can speed up the development of new treatments. Lester Barr, a consultant breast surgeon and founder of the charity Prevent Breast Cancer, stressed the importance of developing new prevention and risk reduction options for women, especially those at high risk due to family history or genetic factors. The research was funded by Prevent Breast Cancer and led by the University of Manchester. Radiography departments in England are set to receive £15.5 million in funding for new AI technology that can detect cancer cells 2.5 times faster than doctors working alone. The AI will automatically review CT or MRI scans, helping doctors distinguish between cancerous and healthy tissue, and reducing damage to healthy organs during radiation treatment. Health and social care secretary Victoria Atkins called the development a breakthrough in improving cancer diagnosis and treatment. Victims of a major miscarriage of justice in British legal history are finally set to have their convictions overturned. Over 700 sub-postmasters were wrongly accused of theft due to an IT error, with some forced to repay money they hadn’t taken and others sent to prison. A law to quash their convictions has been approved by Parliament, applying to England, Wales, and Northern Ireland. The Scottish Parliament is set to pass its own bill to overturn convictions. Lee Williamson, a former sub-postmaster in Northern Ireland, expressed joy at the development. The UK’s postal service has reduced its carbon emissions by replacing diesel fuel with 10 million litres of biofuel at six of its largest sites, preventing around 30,000 tonnes of CO2 emissions. This is part of Royal Mail’s Steps to Zero environment strategy, aiming for net zero emissions by 2040. The biofuel cuts carbon emissions by 90% compared to diesel, and Royal Mail is also switching to electric vehicles to complement the move. A wearable device that delivers an electrical current to spinal nerves has shown life-changing improvements for people with paralysis in a major international trial. Researchers found that combining the Arc-Ex device with standard rehabilitation exercises helped spinal injury patients regain strength and movement in their hands and arms. The improvements were described as profound, with 87% of participants reporting a better quality of life. The device is expected to be approved for use in the US this year. A nature-inspired alternative to toxic pesticides has shown early promise in trials in the Netherlands. The innovation uses a biodegradable 'insect glue' made from edible plant oil, which mimics the natural secretions of some plants. The substance acts like a sprayable fly paper, capturing small pests while leaving larger beneficial insects like bees unharmed. In tests on the western flower thrip, 60% of the pests were captured within two days of spraying. More research is needed to determine its environmental impact. The world’s largest enclosed botanical garden, the Eden Project, was heated using deep geothermal energy this winter, marking the first time in nearly four decades that the UK has used this method. The project drilled a 5km-deep well to generate heat for its offices and biomes, which should nearly eliminate its reliance on gas and save 500 tonnes of CO2 annually. The attraction’s new nursery will benefit from geothermal heat, enabling its horticulture team to propagate and care for one million plants per year. Activists seeking to reverse the decline of the River Wye have unveiled their own four-step manifesto in response to a widely criticized government action plan. The River Wye has suffered from nutrient run-off linked to intensive chicken farming. The UK government plans to fund on-farm poultry manure combusters and provide grants for slurry stores to help restore the river. However, grassroots groups argue the plan lacks ambition and have unveiled their own Manifesto for the Wye, including a 'water protection zone' to shield the river from farm waste and sewage. A display thought to be the most biodiverse in the show’s history and a garden built with 3D printed bricks impressed the judges at the Chelsea Flower Show. The Size of Wales garden, sponsored by a climate change charity, won a gold medal and featured 313 species of plants. Meanwhile, first-time entrant Giulio Giorgi won the show’s inaugural green medal for using 100% sustainable materials, including timber and 3D printed terracotta. The RHS head of sustainability noted a 'seismic shift' in the way gardens are now built and designed.
