Covering current events in science, the environment, technology and health requires a context and reliable sources that respond quickly.
When science hits the headlines, we publish reactions, explanations, and in-depth analysis from reliable sources, capturing both the evidence and the debates. Our library of science journalism resources and the upcoming briefings may be of use to you. Consult our directory of research centres.
We are on the lookout for any controversial information about science (embargoed or not), in order to react with the agility the media needs. Sign up to access our embargoed contents, all under the Creative Commons licence. Find out more about how we work here.
The Nobel Prize in Chemistry 2022 has been awarded to Barry Sharpless and Morten Meldal for laying the foundations of click chemistry, which quickly and efficiently joins molecular building blocks; and to Carolyn Bertozzi, who pioneered bioorthogonal reactions, which use this technique inside living organisms without altering the chemistry of the cell.
A Canadian study published in the Canadian Journal of Cardiology found that adjusted mortality from myocardial infarction is not different between men and women aged 18-55 years, but hospital readmission in the following year is higher in women.
The H5N1 virus that is causing an unprecedented epidemic among wild and domestic birds has a very low capacity to infect humans. The three cases where infection has been found have been due to close contact with dust raised during the handling of affected poultry.

The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics to Alain Aspect, John F. Clauser and Anton Zeilinger for their experiments with entangled photons, establishing the violation of Bell's inequalities and becoming pioneers in quantum information science.
The National Microbiology Centre has confirmed the first positive human case of H5N1 avian influenza detected in Spain, Animal's Health said yesterday. This is the worker of a poultry farm located in the province of Guadalajara who remained asymptomatic and isolated until he tested negative. This is the second case detected in Europe after the UK declared its case in January this year.
The Karolinska Institute has awarded the Nobel Prize in Medicine or Physiology to Swedish biologist Svante Pääbo, a specialist in evolutionary genetics, for his discoveries on the genomes of extinct hominids and human evolution.
The European Medicines Agency (EMA) safety committee (PRAC) has recommended a change to the information on codeine-ibuprofen combination medicines to include "a warning about serious harm, including death, especially when taken for prolonged periods at higher than recommended doses". The PRAC reviewed several cases of renal, gastrointestinal and metabolic toxicity that had been reported in association with cases of abuse and dependence on these drugs.
A study published in the journal PLOS ONE has found an association between paracetamol consumption during pregnancy and attention and sleep problems in these children at three years of age.
Research among more than 7,000 US adults shows small changes in extraversion, agreeableness, openness to change and conscientiousness between the period before the covid-19 pandemic and the year 2022, especially in younger people. The study is published in PLOS ONE.
