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.

Early this morning, an earthquake with a magnitude of 7.8 struck southeastern Turkey and northern Syria. The authorities have reported thousands of deaths and extensive material damage. A second earthquake has occurred further north than the previous one.

A study published in PLOS Medicine estimates that the implementation of sugary drinks taxes in the UK in 2018 was associated with an 8 % reduction in obesity in English girls aged 10-11, particularly among those living in more deprived areas.

A study has analysed the citation patterns of 45 million scientific articles and nearly 4 million patents over the last 60 years. Its conclusion is that scientific and technological innovation is proportionally less and less disruptive, although this characteristic remains constant in absolute terms. The results are published in the journal Nature.

An international study led by Spanish researchers has succeeded in reconstructing the ancestors of the CRISPR-Cas system present in extinct bacteria from up to 2.6 billion years ago. The reconstructed systems work and are more flexible than the current ones. According to the authors, this could open up new avenues for gene editing. The results are published in the journal Nature Microbiology.
