The European Medicines Agency (EMA) has licensed Hipra's vaccine - currently called Bimervax - against SARS-CoV-2 as a booster in people aged 16 years and older who have previously been vaccinated with mRNA vaccines. The EMA began the ongoing evaluation of the vaccine, which was expected to be approved in the middle of last year, on 29 March 2022.

Research published in The BMJ has compared the information on cancer drugs available to regulatory authorities with that officially received by doctors and patients. According to the authors, important information is often omitted. In particular, "none of the package inserts communicated information about the benefits of the drug that patients could expect based on the results of the studies". In addition, doubts raised by European evaluators about the reliability of the evidence "were rarely communicated to physicians, patients or the public," they say.

The Norwegian Academy of Science and Letters has awarded the Abel Prize to Luis A. Caffarelli, a native of Argentina with US-Argentine nationality, for his "fundamental contributions to the theory of the regularity of nonlinear partial differential equations". Considered the Nobel Prize of mathematics, the award recognises work over an entire career - unlike the Fields Medal, which is awarded for a result under the age of 40. Caffarelli has become the first Latin American to receive this award.

Researchers have presented the first connectome - a diagram of neural connections - of the whole brain of an insect, a vinegar fly larva (Drosophila melanogaster). The work, which the authors say will inspire new studies of neural circuits and machine learning architectures, is published today in Science.

A study has analyzed the genetics of 302 dogs living in areas close to the Chernobyl nuclear power plant. According to the study, they show genetic differences according to the distance they live from the plant, which distinguish them from other dog populations. The results are published in the journal Science Advances.

Every February 28 or 29, World Rare Disease Day is celebrated, an initiative that aims to raise awareness about rare diseases in order to improve access to diagnosis and treatment and achieve a better quality of life among those who suffer from them. Here are some frequently asked questions about the most important concepts, their current situation and the main complaints that affected individuals and families continue to have.   

Analysis of the two asymptomatic cases of H5N1 avian influenza detected in Spain in autumn 2022 in workers at a poultry farm in Guadalajara has confirmed the theory that no actual infections occurred, but that both were in contact with genetic material of the virus found in the environment. Spain has recently modified its protocols, according to the analysis published in Eurosurveillance.

A study published in Nature suggests that carbon sequestration is at risk of destabilising in large regions of the planet. In some areas, this sequestration - the difference between the CO₂ captured and released by ecosystems into the atmosphere - has varied greatly in recent years. The research is led by CREAF and the University of Antwerp (Belgium).

A study in mice found that a molecule called TDI-11861 works as an oral male contraceptive, temporarily blocking sperm function. The paper, published in Nature Communications, presents the research as a step towards an on-demand male contraceptive drug: the user could take a birth control pill before sex and become fertile again the next day. Four co-authors of the study have founded a company in the US to develop such products. 

Outbreaks of highly pathogenic H5N1 avian influenza have been increasing since 2021, but in recent months have evolved into what is known as a 'global panzootic' affecting all types of wild birds and new continents, but also mammals such as mink and sea lions. At a briefing organised by SMC Germany, in collaboration with SMC UK and SMC Spain, three experts discussed the situation, the level of risk and possible next steps.
