A team in the US has for the first time achieved quantum teleportation over 30 kilometres of fibre-optic cable already carrying internet data traffic, says a study published in the journal Optica. This type of teleportation would allow quantum communication to be combined with existing internet cable infrastructure.
Researchers in China have analysed data from more than 4,500 people and identified 13 proteins linked to brain ageing. In addition, changes in protein concentrations in the blood tend to peak at ages 57, 70 and 78. According to the authors, who publish the results in the journal Nature Aging, these ages may reflect transitions in human brain health at specific ages, and could therefore be important for designing possible interventions in the brain ageing process.
Unmarried people - whether single, divorced/separated or widowed - have a higher risk of having depressive symptoms than married people, says an international study. The paper, published in Nature Human Behaviour, includes data from more than 100,000 adults in China, Indonesia, Ireland, Korea, Mexico, the UK, the USA and the UK.
Early results from a study of newborn screening methods show that DNA analysis detects many more serious preventable or treatable diseases than standard newborn screening. The study, published today in the journal JAMA, is one of the first large-scale studies in the world to use genome sequencing as a method of newborn screening and is the first to publish preliminary results.
An international team with Spanish participation has analysed which day of the week has the highest risk of suicide mortality, and it is Monday. The research, published in The BMJ, includes more than 1,700,000 suicide cases registered in 26 countries - including Spain - from 1971 to 2019. The data also show a sharp increase in the risk of suicide on New Year's Day in most of the countries analysed. Taking these results into account, the authors propose that they should be used to define plans and awareness-raising campaigns.
A study published in the journal Nature describes a tool capable of inserting watermarks into text generated by large linguistic models - artificial intelligence (AI) systems - thereby improving their ability to identify and track artificially created content. The tool uses a sampling algorithm to subtly bias the model's choice of words, inserting a signature that can be recognised by the detection software.
The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics 2024 to researchers John J. Hopfield and Geoffrey E. Hinton for discovering the foundations that enable machine learning with artificial neural networks. Hinton for discovering the foundational basis that enables machine learning with artificial neural networks. This technology, inspired by the structure of the brain, is behind what we now call ‘artificial intelligence’.
The Karolinska Institute has awarded the Nobel Prize in Medicine or Physiology to Victor Ambros and Gary Ruvkun for the discovery of microRNAs, small RNA fragments that do not contain instructions for making proteins but instead participate in the regulation of gene expression. Their role is fundamental in processes such as cell differentiation, and their alteration can influence diseases like cancer.
Large language models - Artificial Intelligence (AI) systems based on deep learning, such as the generative AI that is ChatGPT - are not as reliable as users expect. This is one of the conclusions of international research published in Nature involving researchers from the Polytechnic University of Valencia. According to the authors, in comparison with the first models and taking into account certain aspects, reliability has worsened in the most recent models, such as GPT-4 with respect to GPT-3.
Eating a vegan diet for eight weeks is associated with reductions in biological age estimates based on levels of DNA methylation, a type of chemical modification of DNA that alters the expression of genes, but not the DNA itself. This is the main conclusion of a study published in BMC Medicine in which 21 pairs of twins participated in a clinical trial. Of each pair, one person followed an omnivorous diet and the other a vegan - and lower calorie - diet during that period.
