Mathematics shows that every electoral system must compromise among proportionality, local representation, and parliament size. Denmark’s 2022 national election came down to a single seat, even though its proportional voting system was designed to make party representation closely match the vote. That outcome points to a deeper mathematical problem: no electoral system can always preserve [...]

A new study suggests evolution stayed stuck for millions of years until sexual reproduction helped unleash a burst of biodiversity. New research suggests that the earliest animals on Earth may have unintentionally slowed the pace of evolution for millions of years. Scientists have found that their reliance on asexual reproduction limited competition and reduced the [...]

A groundbreaking AI-designed vaccine aims to protect against not only today’s coronaviruses, but tomorrow’s as well. A new type of universal coronavirus vaccine has passed its first test in humans, marking an important step toward broader protection against future viral threats. Researchers from the University of Cambridge and biotechnology company DIOSynVax (DVX) Ltd reported that [...]

Cambridge researchers used lab-grown human brain and spinal cord tissues to uncover a hidden mechanism that blocks nerve repair. By reversing that biological brake, they restored the ability of damaged nerve fibers to regrow. Scientists at the University of Cambridge have created miniature brain and spinal cord circuits in the lab that mimic the neural [...]
