For science to make the news in a rigorous and attractive way, good sources are needed. Because access to scientific knowledge is a citizen's right.
We’re on the lookout for controversial information about science and we will contact you for your analysis in your area. Do you want to be part of our sources? Contact us. We will not pass your contact details on to anyone else. You can find out more about how we work here.
In the midst of an energy, economic and geopolitical crisis, and still in a pandemic, the Climate Summit in Egypt (COP27) will kick off on 6 November with the challenge of bringing the climate fight to the forefront. We explain the main stumbling blocks, the unfinished business from the previous summit and the goals it has set itself.
The WHO has published the first list of priority fungal pathogens, which affect more than 300 million people and kill at least 1.5 million people every year. However, funding to control this scourge is less than 1.5 % of that devoted to infectious diseases.
A study published in Science Advances estimates that economic losses due to heatwaves caused by climate change between 1992 and 2013 exceeded $5 trillion. Moreover, lower-income countries were more affected than richer regions.
A systematic review and meta-analysis published in JAMA Network Open examines whether there is an association between newborn exposure to SARS-CoV-2 and impaired neurodevelopment compared to those born before the pandemic. Neurodevelopment in the first year of life was not modified by being born or growing up during the covid-19 pandemic or by gestational exposure to SARS-CoV-2. However, the authors appreciated that, regardless of whether maternal infection was present, the pandemic was associated with a risk of delayed communication in these infants.
The Basque Coast Geopark has recently hosted the presentation of the first 100 geological heritage sites of the International Union of Geological Sciences. The flysch of Zumaia (Gipuzkoa), the mercury mines of Almadén (Ciudad Real) and the volcanic relief of La Palma (Santa Cruz de Tenerife) are among those chosen.
A study published in the BMJ looks at the risk of thromboembolic events associated with different covid-19 vaccines, both adenovirus- and mRNA-based. Its results are based on data collected from more than 10 million adults in France, Germany, the Netherlands, Spain, the UK and the US who received at least one dose of a covid-19 vaccine from December 2020 to mid-2021.
Today the European Commission proposed revising the air and water quality directives in line with World Health Organisation recommendations. These would include more than halving the annual limit value for fine particulate matter (PM2.5).
The Spanish Confederation of Scientific Societies (COSCE) has just published a report, submitted to the EU, which proposes and compares different possibilities for reform of the regulatory framework for genome editing techniques.
A study published in the journal Nature Communications in mice has associated the inhalation of e-cigarette aerosols with heart rhythm disorders, including ventricular arrhythmias.
The IceCube collaboration, with its detector located under the Antarctic ice sheet, has used astrophysical neutrinos to search for changes in the structure of space-time. In the research, published in Nature Physics, the team analysed more than seven years of data and found no signs of a modified structure of space-time imprinted in the characteristics of these particles, a further step towards understanding quantum gravity.
