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 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 receive our embargoed contents, all under the Creative Commons licence. Find out more about how we work here.
A press release from Eli Lilly claims that its antibody treatment, donanemab, significantly slowed cognitive and functional decline in a phase 3 study of early-stage Alzheimer's disease. The results have not yet been published in a scientific journal.
A US team has developed a non-invasive language decoder: a brain-computer interface that aims to reconstruct whole sentences from functional magnetic resonance imaging (fMRI). This is not the first attempt to create such a decoder; some of the existing ones are invasive - requiring neurosurgery; others are non-invasive, but only identify words or short phrases. In this case, as reported in the journal Nature Neuroscience, the team recorded brain responses - captured with fMRI - of three participants as they listened to 16 hours of stories. The authors used this data to train the model, which was then able to decode other fMRI data from the same person listening to new stories. The team argues that the model trained on one person's data does not decode another person's data well, suggesting that cooperation from the subject is required for the model to work properly.
A new scientific statement from the American Heart Association published in the journal Circulation analyzes how several diets (including Mediterranean, Paleo, and ketogenic) fit into the guidelines for a heart-healthy diet. The ketogenic and 'paleo' diets were not classified as heart-healthy.
A study by Spanish researchers coordinated by CEU San Pablo University has analyzed the factors associated with poor prognosis in case of influenza infection. After analyzing data on 48,000 patients from 135 investigations in 28 countries, they conclude that bacterial superinfections increase the risk of death 3.4 times. The authors propose to increase early diagnostic measures so that antibiotics can be administered quickly in cases where there is a higher risk of complications. The results are published in the International Journal of Infectious Diseases.
The hydrological, meteorological and agricultural drought that is being experienced in Spain, especially in some regions, comes after a 2022 that was the warmest and one of the driest since records have been kept. Researchers Sandra García Galiano (UPCT) and Annelies Broekman (CREAF) participated in an informative session of SMC Spain in which they analyzed the causes, consequences and possible solutions to face this complex natural phenomenon.
A phase 2 clinical trial has analysed the safety and efficacy of adding immunotherapy to traditional chemotherapy to treat a subtype of acute lymphoblastic leukaemia in children under one year of age. This subtype of leukaemia, although rare in absolute terms, is the most common in children of this age, and its prognosis in this age group had not improved in recent years. The immunotherapy used, a bispecific antibody that binds to tumour cells on the one hand and T lymphocytes on the other, improved two-year survival from 66% to 93% in treated patients, according to The New England Journal of Medicine (NEJM).
The current situation is only the beginning of what may come in the coming decades, which should lead us to increase efforts in mitigation and adaptation strategies: more green and shaded areas, energy efficiency in buildings and avoiding working outdoors in extreme temperatures.
The State Meteorological Agency (AEMET) has reported that, from Tuesday, the progressive entry of a mass of very warm and dry air of African origin over the peninsula and the Balearic Islands will cause exceptionally high temperatures for this time of year, with values typical of summer. According to AEMET, during Thursday 27, the threshold of 30 ºC is likely to be exceeded throughout the southern half, as well as on the banks of the Ebro. On the other hand, 35 ºC is likely to extend to the Guadalquivir valley in Córdoba and Jaén. During Friday it is possible that 35 ºC will be exceeded in the banks of the Ebro in Zaragoza and other points of the southern half, in addition to the Guadalquivir valley, where the maximum temperature values could be around 38-40 ºC.
Faecal microbiota transplantation can be administered by oral capsules, colonoscopy or rectal enema, among other routes. Two meta-analyses evaluate its benefits and side effects for treating two types of disease. The first focuses on recurrent infections with Clostridioides difficile, a bacterium that can cause very severe diarrhoea; it includes six studies in Europe and North America involving 320 adults and concludes that in immunocompetent people, faecal transplantation is more effective than antibiotics. The second focuses on irritable bowel diseases, such as ulcerative colitis and Crohn's disease; it includes 12 studies with 550 participants and has less clear results.
Species of birds common in the marshes of Doñana as the common tern, the brown pochard, the marbled teal, the marsh harrier or the black-bellied sandpiper have recorded a decline in their population for more than a decade, a trend that accelerated since 2019. This is one of the conclusions of the Report on the conservation status of waterfowl in Doñana, published today by SEO/BirdLife.
