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.
About 58.5% of a baby's microbiota come from various parts of its mother's body, according to a study of the transmission of microbes between mother and child in the first month of life. The research, published in Cell Host & Microbe, is based on samples collected from 120 mother-baby pairs, with material from their nose/throat, saliva, skin, milk, vagina and faeces. It compares babies born by caesarean section and vaginally, and confirms that the reduced transfer of faecal microbes in caesarean births can be partially compensated by other transmission routes, such as breastfeeding.
This year's theme for 8M is "For an inclusive digital world: innovation and technology for gender equality". If we want to innovate for everyone, there must be women doing research in mathematics, an essential discipline in the fields of technology, finance and health. However, the future of mathematical research in Spain has a male profile and this is worrying: advances and major decisions will be made excluding half of the population.
People who had a lower respiratory tract infection—such as bronchitis or pneumonia—before the age of two have twice the risk of premature death from respiratory disease in adulthood, according to a study published in The Lancet. The research is based on long-term data from over 3,500 people born from 1946 onwards in England, Scotland and Wales. According to the study, one in five premature deaths in this representative sample could be due to respiratory infections. The team adjusted their estimate by taking into account factors such as socioeconomic status in childhood and smoking in adulthood.
An analysis published in Nature Climate Change estimates that food consumption worldwide could add 1°C to global warming by 2100. The study also says that more than half of this warming could be avoided by adopting a healthy diet, improving food system practices, and reducing food waste.
Un estudio ha estimado las muertes por cáncer que se producirán en la Unión Europea y el Reino Unido en 2023. Comparándolas con las observadas en 2018, estiman que se reducirán en un 6,5 % en hombres y un 3,7 % en mujeres de forma global. Sin embargo, en España aumentará la mortalidad por cáncer de pulmón en mujeres. Los resultados se publican en la revista Annals of Oncology.
The deadline passed and after two marathon nights of meetings, the delegations of the UN member states have managed to reach an agreement to make the so-called Oceans Treaty - or BBNJ Treaty, Biodiversity Beyond National Jurisdiction - a reality. New York City has seen the fifth session of this conference bear fruit with an agreement on the wording of the text, seventeen years after the talks began and with negotiations stalled last August due to a lack of agreement. The Treaty aims to protect and regulate the use of areas beyond national jurisdiction, which account for more than 60% of the oceans, or almost half of the planet. Marine genetic resources and how to share these benefits has been one of the main stumbling blocks.
Obesity is a growing public health problem for the entire planet. According to the 2023 Obesity Atlas published this week by the World Obesity Federation, 51% of the world's population will be overweight or obese (more than 4 billion people) by 2035, up from 38% today. At a briefing organised by SMC Spain ahead of World Obesity Day on 4 March, two experts discussed the role that drugs can play in combating a disease whose roots are social and linked to inequality.
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.
The Centre for the Coordination of Alerts and Health Emergencies (CCAES) reported yesterday that last February Germany reported two cases of dengue (one confirmed and one probable), along with four cases compatible with epidemiological links, in residents of Germany who had travelled to Ibiza during the incubation period. One of the potential vectors of dengue is the Aedes albopictus mosquito, which was first detected in Ibiza in 2014. According to the CCAES, the risk of new autochthonous cases appearing in Ibiza, "at this time of low vector activity, is considered low".
