Work by the Institute for Health Metrics and Evaluation (IHME) estimates that by 2050, more than three quarters (155 out of 204) of countries will not have fertility rates high enough to maintain their population size. The percentage will rise to 97% by the year 2100. The authors warn that national governments must plan for the threats these changes will pose to the economy, food security, health, the environment and geopolitical security. The findings are published in the journal The Lancet. 

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.

Every school year in Spain, the debate returns about what kind of timetable schools should adopt: is it better to concentrate all teaching hours or to have a lunch break and extend the time spent at school? In this first issue, we bring together research on the effect of each type of timetable on students' performance, rest and socio-affective well-being, as well as the available data on public and charter education.

A study led by researchers from Northeastern University and Stanford University in Boston (USA) has analysed the source of exposure to partisan or unreliable news when searching on Google. After tracking the information consumption of approximately 1,000 people in the 2018 and 2020 US election periods, their conclusions are that such exposure is determined more by users' own active search than by the content displayed by the search engine's algorithm. The results are published in the journal Nature.

More than two thirds of Spanish citizens think that artificial intelligence presents a very high or high risk that we will be manipulated with our data by companies or governments. However, just over a third believe that artificial intelligence will have an impact on improving the quality of public services and companies. These are some of the results gathered in the 2022 edition of the Survey of Social Perception of Science and Technology published today by the Spanish Foundation for Science and Technology (FECYT), carried out among more than 6,000 people with face-to-face interviews in the 17 autonomous communities.

The message that we must continue to protect ourselves with masks, distance, ventilation and hand washing has been repeated since the beginning of vaccination, but in the midst of the pandemic in Europe it is even more important. Several experts warn that the high vaccination coverage in Spain will mitigate the new wave but will not eliminate it: although vaccines prevent serious disease, they are not an insurmountable shield and must be complemented with behavioral measures.

European countries are implementing anti-covid strategies in the unvaccinated population. Austria will make vaccination mandatory after extending its confinement targeting the unvaccinated to the entire population. In Germany, the unimmunized have restricted access to restaurants and hotels, and must show a negative test on public transport. Slovakia has also imposed restrictions on those who have chosen not to be vaccinated. Sweden will introduce a covid passport at events of more than 100 people. What is the effect of these policies?

With the goal of vaccines reaching a huge part of the European population achieved, we must provide scientific evidence and action to ensure that all people have access to immunisation. We will find herd immunity by vaccinating and monitoring infections now more than ever.
