Scientists and conservationists are debating de-extinction, the idea of bringing extinct species back using modern genetic tools. Advances such as PCR, genome sequencing and gene editing have made it technically plausible to reconstruct genomes from preserved DNA. Companies like Colossal Biosciences aim to use these methods to create proxy woolly mammoths by editing Asiatic elephant DNA. Proponents argue such projects could help restore lost ecological functions and biodiversity.

Research compiled by YouGov shows that the COVID-19 pandemic prompted different changes in daily routines around the world. In some places people slept more—Saudi Arabia, Brazil, China and Turkey reported increases—while Australians and Britons admitted to drinking more and residents of Mexico, Brazil and Spain reported cutting back on alcohol. Exercise rose in countries including China, Saudi Arabia, Mexico and the United States, and various nations reported shifts in diet quality.

Researchers presented new findings at the European Society of Cardiology meeting showing that laughter therapy can improve some measures of heart health in people with coronary artery disease. In the study, patients took part in guided laughter sessions while researchers measured inflammation markers and cardiovascular performance before and after. The reported results included lower inflammation and improved indicators of heart function after the laughter interventions.

Researchers report that reef-dwelling hogfish have light-sensitive cells embedded in their skin, allowing the animals to sense brightness and adjust their colour without relying solely on eyes. The study, published in Nature, shows this skin-based photoreception can continue to influence colour change even after death. Hogfish live in Atlantic reefs and can shift hues in milliseconds. Those rapid changes aid camouflage, social signalling and may help with temperature regulation and attracting mates.
