Today in this week's scientific news summary: zoologists discovered how a variety of creatures - bats, birds and leeches to butterflies, spiders and snails - became vampires and what difficulties they overcame along the way. The number of people suffering from anorexia and bulimia has increased by 71% since 1990. High-income areas were hit hardest. What else has the global assessment of the burden of these diseases shown? OpenAI and Anthropic models disproved the exponential time hypothesis, one of the central assumptions of the computational complexity theory of problems from various areas of computer science. More discoveries and studies in the link. Photo: AR.
