Electronic cigarettes: a quick guide to the different types, their risks and whether they are useful to quit smoking

E-cigarettes, vapes, pods, mods... The popularity of these devices continues to grow, especially among young people. According to a Spanish survey, more than half of the adolescents aged 14 to 18 have used them at some point. Vaping control varies from country to country: in Spain, vaping products have been regulated since 2017 and the new anti-smoking plan aims to equate their legislation to that of tobacco, while the United States imposes fewer restrictions. In this brief guide, we explain what is known and not known on controversial issues such as the safety of electronic cigarettes, their risks or whether they are useful to quit tobacco.

¿Qué sabemos sobre la mala conducta científica? Guía para informar sobre integridad en la investigación

Según una encuesta llevada a cabo en España, respondida por 403 investigadores en biomedicina, cuatro de cada diez admiten haber cometido algún tipo de mala práctica en su trabajo.

Entre los casos más recientes, El País informó de que el CSIC ha abierto un expediente disciplinario a cinco personas por sospechas de recibir dinero a cambio de afiliaciones falsas. Estas malas conductas pueden parecer aisladas, pero reflejan disfunciones más amplias del sistema de investigación. Ofrecemos claves para entender cómo nacen y evolucionan estos casos, y para cubrir sus matices.

Continuous or split school day: arguments in the debate

When considering which type of timetable is best, one question is: best for what and for whom? Not only does the scientific evidence on student learning and well-being come into play, but also the employment interests of teachers, the reconciliation needs of families, and the effects of each type of timetable on socio-economic inequality and the gender gap in care are also involved. We bring together more elements of the discussion in this second article.

Sixth-generation wildfires: what they are, how climate change affects them and ways to prevent them

Rising temperatures, droughts, heat waves and abundant untreated material in forests are the perfect cocktail for fires to break out. When they are beyond the control of firefighting services - because of their intensity, speed and unpredictability - we speak of mega-fires or sixth generation wildfires, a phenomenon that is not new but whose frequency could increase due to rural abandonment and climate change. Some experts have thus described the fire in Tenerife that began on August 15 and has forced the evacuation or confinement of thousands of people.
