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 study published today in Nature Genetics examines AstraZeneca's new tool, MILTON, which uses artificial intelligence to detect biomarkers and predict diseases before they are diagnosed. According to this analysis, the tool could potentially predict over a thousand diseases and may even be more effective than the currently available polygenic risk scores.
A new study presented at the annual meeting of the European Association for the Study of Diabetes (EASD), being held in Madrid from September 9-13, and published simultaneously in the New England Journal of Medicine (NEJM), has revealed that liraglutide, an anti-obesity drug, is safe and effective in children aged 6-12 years.
Ahead of World Suicide Prevention Day on September 10, a new series of six articles published in The Lancet Public Health calls for a shift in the narrative. Experts advocate for moving beyond framing suicide solely as a mental health issue, emphasizing the need to recognize the impact of social factors such as poverty, debt, addiction, homelessness, abuse, discrimination, and social isolation.
Brain maturation is measured by the thickness of the cortex. It is known that stress accelerates cortical thinning, which is associated with a higher risk of developing neuropsychiatric disorders. A study published in PNAS analyzes MRI data collected from 160 adolescents before COVID-19 and from 130 of them after the measures implemented during the pandemic. The comparison of brain structure before and after reveals accelerated cortical thinning which, measured in terms of equivalent years of brain development, was 4.2 years in girls and 1.4 years in boys.brain maturity
More than 60 % of the world's cities receive more precipitation than the rural areas around them, according to a study published in PNAS. The paper cites southern European cities such as Milan and Barcelona as examples of these ‘notable anomalies’, but adds that this phenomenon is not common in central and northern Europe. The research team analysed satellite and radar data from more than 1,000 cities around the world between 2001 and 2020.
A case-control study published in JAMA Pediatrics reports a relationship between certain aberrant metabolic biomarkers at birth and sudden infant death syndrome (SIDS). Although the research is preliminary and no screening test for this syndrome is yet available, the researchers believe their study is an important step toward integrating metabolic and genetic markers to identify infants at higher risk of sudden death.
A team of researchers at Stanford University (USA) has developed a technique that makes animal tissues transparent in vivo and reversibly. Based on a food dye, they have tested it topically on mice. According to the authors, who publish their research in the journal Science, “this technology could make veins more visible for blood collection or help in the early detection and treatment of cancer”.
A study has analyzed data on prostate cancer incidence and mortality in 26 countries in Europe between 1980 and 2020. Its findings are that new diagnoses have increased due to the widespread use of PSA [prostate-specific antigen] testing, but mortality rates have not benefited in parallel. This suggests possible overdiagnosis, i.e., the detection of harmless tumors that are unlikely to cause symptoms or death in the patient's lifetime. The results are published in the journal The BMJ.
A study carried out in China has analyzed tissues from 461 fur animals, mostly farm-raised. They found 125 virus species, 39 of which presented a high risk of interspecies transmission. According to the authors, who publish the results in the journal Nature, “there is a need for more extensive and regular surveillance to assess the public health risks that could result from fur animal farming”.
More than 52 million tonnes of plastic waste are emitted around the world every year, according to a study published in Nature that inventories plastic pollution in 50,702 cities. It concludes that littering is the largest source of plastic emissions in the global North, and uncollected waste is the largest source in the South.
