There are growing concerns that the research system no longer benefits science or scientists. The pressures to publish and obtain funding, along with a lack of job security for early-career researchers, have created a working environment that values novelty and quantity over rigor and quality, sometimes at great personal cost. The articles in this selection explore a variety of topics within the broad area of 'research culture'. Other aspects of research culture are covered in our collections on mental health, being a scientist and parent, equity, diversity and inclusion, and being neurodivergent in academia. eLife also runs a number of initiatives to improve research culture.
