An international team of scientists from the KM3NeT collaboration has detected the signal from the highest-energy cosmic neutrino to date, some 30 times higher than those previously detected. The result suggests that the particle came from beyond the Milky Way, although its precise origin has yet to be determined. The results are published in the journal Nature.
A multidisciplinary team of US researchers has analyzed the presence of micro- and nanoplastics in 52 human cadavers between 2016 and 2024. The concentrations of these particles were higher in the brain than in the liver or kidneys. They were also higher in the brains of people with dementia, although the researchers acknowledge that causality cannot be established. The results are published in the journal Nature Medicine.
A meta-analysis that brings together data from 628 species of animals, plants and other organisms in terrestrial and marine ecosystems over the last three decades shows that most are losing genetic diversity, especially mammals and birds. ‘The threats affected two thirds of the populations we analysed and less than half are subject to conservation management measures,’ say the authors of the research, published in Nature.
A team of researchers has used embryonic stem cell engineering to create a bipaternal mouse - a mouse with two male parents - that lived to adulthood. Their results, published in the journal Cell Stem Cell, show how targeting a particular set of genes involved in reproduction enabled this breakthrough in unisexual reproduction in mammals.
A team of researchers from the USA has analyzed the B lymphocytes of seven healthy people in whom no exposure to H5 influenza viruses, such as the avian flu virus, had been documented. The results show that they present antibodies capable of recognizing this type of virus, which, according to the authors, could represent “a first line of defense” in the event of a pandemic. The results are published in the journal Science Immunology.
A study in mice reveals that immune cells in the brain 'engulf' microplastics, forming clumps that can cause brain clots. The findings, published in the journal Science Advances, highlight how microplastics can indirectly damage the brain by disrupting blood flow, rather than directly infiltrating brain tissue cells.
An assessment of the extinction risk of freshwater fauna, covering more than 23,000 species, reveals that around 24% of the species studied are at risk of extinction. The analysis, published in Nature, identifies the main threats from pollution, dams, agriculture and invasive species. Decapods - such as freshwater crabs and shrimps - have the highest percentage of threatened species (30 %), followed by freshwater fish (26 %) and odonates - such as dragonflies (16 %).
Meeting in the city of Windoek (Namibia), the plenary of the IPBES - Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services - has ratified two new reports: the Nexus Assessment and the Transformative Change Assessment. Three of their authors explained the main findings and the changes they propose at a briefing organised by SMC Spain.
Thirty eight scientists from different specialties, including Craig Venter, a pioneer in the creation of artificial synthetic life, have written an article in the journal Science in which they assess the possibilities of synthesizing mirror organisms, but also warn of the risks they pose. This type of microorganisms, which would present a mirror structure to that currently found in nature, would have potential applications due to their resistance to biological degradation. However, they would also pose a danger because they would not be recognized by our defenses and could spread in ecosystems. Scientists call for more research and a broad debate, and warn that until more is known, this type of organism should not be created.
A team of researchers has analyzed more than 300 human genomes from the last 50,000 years and has concluded that most of the gene flow we received from Neanderthals is attributable to a single period, which probably occurred between 50,500 and 43,500 years ago. In addition, Neanderthal inheritance underwent rapid natural selection in subsequent generations, especially on the X chromosome, according to a study published in Science.
