Researchers in Japan have developed a new material that allows solar cells to generate an amount of energy from sunlight that was previously thought impossible. The discovery, made by a team at Kyushu University, involves a special “spin-flip” emitter that can harvest energy from the Sun that is typically lost as heat. The breakthrough overcomes the long-standing limit of conventional solar cells to achieve an energy conversion efficiency of 130 per cent – opening up new possibilities for ultra-efficient solar panels.

Depleting THAAD and Patriot interceptor inventories threaten US extended deterrence, Gulf energy security, and the regional power balance amid sustained Iranian ballistic missile and drone assaults.

Three major Defence Agencies are quietly admitting what most still refuse to face: climate breakdown is coming for our food, and the cracks are already spreading. While the wealthy cling to logistics and illusion, the real defence strategy is soil and local growers who refuse to let their communities starve.

From floods to droughts, erratic weather patterns are affecting food security, with crop yields projected to fall if changes are not made

Exclusive: UCL scientists find large swathes of southern Europe are drying up, with ‘far-reaching’ implications

EU officials warn climate breakdown and wildlife loss ‘are ruining ecosystems that underpin the economy’ […] The European way of life is being jeopardised by environmental degradation, a report has found, with EU officials warning against weakening green rules. The continent has made “important progress” in cutting planet-heating pollution, according to the European Environment Agency, but the death of wildlife and breakdown of the climate are ruining ecosystems that underpin the economy.

Earth’s average temperature rose more than 1.5°C above pre-industrial levels in 2024 for the first time – a critical threshold in the climate crisis. At the same time, major armed conflicts continue to rage in Ukraine, Gaza, Sudan and elsewhere. What should be increasingly clear is that war now needs to be understood as unfolding in the shadow of climate breakdown. The relationship between war and climate change is complex. But here are three reasons why the climate crisis must reshape how we think about war.

Extreme heat is breaking records around the world, with wildfires and poor air quality compounding the crisis, according to a report from the World Meteorological Organization (WMO) released Thursday.

António Guterres says ‘sun is rising on a clean energy age’ as 90% of renewable power projects cheaper than fossil fuels

Heat caused 2,300 deaths across 12 cities, of which 1,500 were down to climate crisis, scientists say
