Sikojen hermosoluja ihmisaivoissa? Vuoden 2025 tilannekatsaus hermosolujen ksenotransplantaatioon—läpimurrot, riskit ja mitä seuraavaksi tapahtuu

Mitä neuronien ksenotransplantaatio tarkalleen on? Neuronien ksenotransplantaatio on hermojen tai niiden esiasteiden siirtämistä lajien välillä, käytännössä useimmiten geneettisesti muunnelluista sioista ihmispotilaisiin. Se eroaa allograftista (ihmiseltä ihmiselle) ja organoiditutkimuksesta, jossa ihmisen soluja laitetaan eläimiin mallinnusta varten. Terapeuttisena tavoitteena on korvata tai muokata hermoverkkoja,

  • AI deepfakes push victims into jail as evidence goes unchecked
    January 9, 2026, 3:48 AM EST. Melissa Sims says her ex-boyfriend used AI-generated texts to frame her, landing her in a Florida jail for a bond violation after she called police during an argument. The texts disparaged him and were not verified, prosecutors later dropped the bond violation, and she went to trial on a battery charge eight months after the initial incident. Judges and experts warn that AI-generated deepfakes-texts, video and images-pose a growing risk to the justice system, with detection tools lagging behind. Drexel's Rob D'Ovidio notes the difficulty of spotting synthetic material; he demonstrated with an AI-generated photo and several detectors giving divergent results. Officials urge a framework and more due diligence before charging, while Sims' case shows the real-world harms of unverified evidence.
