Experts identify common causes of fatigue and poor sleep, including high CO2 levels in bedrooms, low creatine stores, insufficient daylight exposure, lack of fibre, and late-night eating, offering simple lifestyle adjustments to improve energy and rest.
Crop nutrient content has declined for decades, prompting research into solutions. Regenerative agriculture, focusing on soil health, shows promise in boosting nutrient density in some studies, but faces skepticism regarding scalability and cost-effectiveness.
Scientists are exploring enhanced rock weathering (ERW), a method of spreading finely crushed volcanic rock on farmland to remove atmospheric carbon dioxide. This technique accelerates a natural geological process, potentially improving soil health and crop productivity while utilizing existing agricultural equipment, but requires careful monitoring and verification.
A new study reveals how changes in sea level influenced ocean phosphate levels, which in turn affected atmospheric carbon dioxide and regulated Earth's climate over the past 60 million years. Published in PNAS, the research identifies a crucial part of the planet's natural climate control system involving marine organisms.
Experts and environmental groups criticize the UK's carbon capture and storage (CCS) plans, arguing they are costly, ineffective against methane emissions, and primarily support new fossil fuel infrastructure rather than hard-to-abate industries.
Microsoft, Amazon, and Google's combined carbon emissions increased by nearly a fifth in the past year, reaching 119m mTCO₂e, largely due to datacentre construction for AI. This surge contrasts with previous efforts to reduce emissions and highlights concerns about the ecological impact of cloud computing and AI development.
China aims to peak emissions within five years, targeting a 17% reduction in CO2 emissions per GDP unit by 2030 and increasing non-fossil energy share to 25%. The plan emphasizes clean coal substitution, nuclear power, and green energy sources to meet soaring electricity demand from its AI sector and ensure energy security.
Scientists at NTU in Singapore developed a process converting discarded shrimp shells into carbon-negative hydrogen fuel, aquaculture protein, and calcium carbonate. This lab-scale technology aims to reduce waste and offer cleaner alternatives to fossil-based energy and industrial materials, though commercial scaling faces efficiency and economic hurdles.
Scientists in Singapore have developed a process to convert shrimp shells and other organic waste into hydrogen fuel, protein for aquaculture feed, and calcium carbonate for construction. The technology, developed at Nanyang Technological University, aims to be carbon-negative by removing more CO2 than it produces, offering a dual solution for waste reduction and cleaner energy.
A proverb suggests the ocean stores secrets at a 'salt' cost, altering its composition. This reflects how absorbed elements, from geological minerals to human waste, change the sea. The concept applies to human memory, systems thinking, digital storage, and unresolved conflicts, highlighting that containment alters the container.
Chinese startup Zhiyu Aerospace Technology plans to use supercritical carbon dioxide for rocket launches, aiming for low-cost, high-frequency commercial flights. The technology ejects rockets using high-pressure CO2, igniting engines mid-air to avoid ground platform contact.
Scores of Labour MPs are pressuring prospective prime minister Andy Burnham to reject the Rosebank oilfield development in the North Sea, citing new research that estimates 250m tonnes of CO2 emissions over its lifetime, equivalent to 70% of the UK's annual emissions, and arguing it won't reduce fuel prices or significantly boost the economy.
A new study in Nature Communications used rhenium isotopes from ancient seabed sediments to analyze the Toarcian Ocean Anoxic Event 183 million years ago. Researchers found that eroding organic carbon amplified global warming, suggesting a similar process may affect modern climate change, though its extent remains uncertain.
The Albanese government approved regulatory changes allowing NSW to receive carbon credit funding for protecting native forests, enabling the creation of a 176,000-hectare koala national park near Coffs Harbour. The move, an election commitment, is praised by some conservationists but criticized by others and industry for relying on contentious carbon offsets.
A UK company, VolcanoTech, has developed a low-cost air quality sensor using a modified smartphone camera and Raspberry Pi. These sensors detect sulphur dioxide, a key indicator of imminent volcanic eruptions, and are being deployed in countries like Ecuador and Indonesia, offering a cheaper alternative to existing systems.
Geoengineering, particularly solar geoengineering, is presented as a risky techno-optimistic "quick fix" for climate change. Critics argue it masks warming, poses termination shock risks, requires centuries of maintenance, and lacks scientific understanding and governance, diverting resources from decarbonization.
Fifa president Gianni Infantino aims to attend two World Cup games daily, utilizing a private jet provided by Qatar Airways. This ambitious schedule spans the US, Canada, and Mexico, covering vast distances and multiple time zones, a stark contrast to the more compact 2022 Qatar World Cup.
A new study suggests trees might not store as much planet-heating carbon as previously thought. Researchers found that tree growth stops months before photosynthesis does, meaning not all absorbed carbon is converted into wood. This could impact climate models and the effectiveness of forests as carbon sinks.
Shipbuilders in South Korea's Daebul Industrial Complex are concerned about the supply of carbon dioxide, a crucial material for welding, due to the prolonged conflict in Iran. Disruptions in petrochemical plants, which produce CO2 as a byproduct, are impacting availability, with fears of further shortages as summer demand for dry ice increases.
Weakened UK electric car sales rules may increase CO2 emissions by 17m tonnes by 2030, driven by a 48% rise in plug-in hybrid electric vehicle (PHEV) sales, which emit more than anticipated due to underuse of battery mode.
The 2026 World Cup faces criticism for its massive environmental impact, projected to be the "most polluting" ever due to increased teams and vast host countries. Concerns also include eye-watering ticket prices, political tensions, and player safety amid extreme heat.

India is burning more coal to meet surging electricity demand caused by extreme heatwaves and energy supply disruptions linked to the conflict in the Middle East, challenging the nation's long-term net-zero goals.
Researchers published a study in ACS Catalysis on April 15 detailing a process to convert carbon dioxide directly into long-chain chemicals suitable for jet fuel. The method essentially runs combustion in reverse, recombining waste gas with water to create energy-dense liquid fuel. The breakthrough addresses two major obstacles that have historically hindered this chemical process: carbon chain growth difficulties and low yields of valuable long-chain products.
