Cocoa traded above $12,000 a tonne in 2024 and around $4,700 in November 2026. Chocolate prices have not followed, because manufacturers buy cocoa months in advance and are still working through beans bought near the peak.
The EU AI Act's bans and general-purpose AI rules already apply, and transparency duties started in August 2026. A 2026 amendment pushed the main high-risk obligations back to December 2027 and August 2028.
Home fermentation is safe when you follow tested methods: the right amount of salt, vegetables kept under brine, steady temperatures and clean equipment. Official US guidance also says to discard anything mouldy, foul-smelling or in a bulging container.
Trials of a four-day week on full pay have consistently found less burnout and few signs of lost output, and most participating employers keep the model. The evidence is promising but comes mostly from organisations that chose to take part.
GLP-1 medicines such as semaglutide and tirzepatide are now approved in the US to cut heart, kidney and liver risks and to treat sleep apnoea. Not every hope has held up: a large Alzheimer's trial failed in 2025.
A heat pump moves heat from outside air or the ground into a home, delivering more heat than the electricity it uses. European sales rose 13% in 2025 after two years of decline, led by Germany.
Long-term memories last because the brain strengthens connections between neurons, then reorganises and reinforces them over days to years, much of it during sleep. Recent mouse studies have identified molecules and gene programmes that keep memories stable.
Most adults need at least seven hours of sleep a night, and the main expert ranges are seven to nine hours, or seven to eight after 65. A 2026 review of a decade of research left those ranges unchanged.
Lithium-ion batteries can be recycled by smelting, chemical leaching or newer direct methods, recovering metals such as lithium, cobalt and nickel. About a fifth of battery lithium is now recycled, and the EU requires 50% recovery by the end of 2027.
