Pig Neurons in Human Brains? The 2025 Reality Check on Neuron Xenotransplantation—Breakthroughs, Risks, and What Happens Next

Prasečí neurony v lidském mozku? Realita roku 2025 v xenotransplantaci neuronů—průlomy, rizika a co nás čeká dál

Co přesně je xenotransplantace neuronů? Xenotransplantace neuronů je transplantace neuronů nebo jejich prekurzorů mezi druhy, nejrealističtěji z geneticky upravených prasat do lidských pacientů. Liší se od alograftů (člověk‑člověku) a od výzkumu organoidů, který vkládá lidské buňky do zvířat pro modelování. Terapeutickým cílem

  • Powering the AI race: US and China weigh energy bets amid competition
    January 9, 2026, 3:18 AM EST. Four authors from the Global China project examine how rising energy demand from AI could reshape the US-China tech rivalry. The United States retains an edge in cutting-edge AI chips, but China holds a broader energy advantage that could tilt compute toward Beijing. US data centers may need as much as 426 TWh by 2030, while China could reach about 277 TWh, according to IEA projections. China already generates more than twice US electricity and has grown power output around 6% annually, with more than half of that from clean energy such as wind, solar and hydropower. Data centers now demand up to a gigawatt per facility, stressing grids and shaping where AI gains occur. The debate covers whether Washington should embrace or restrict Chinese investment in American clean energy tech, and which regions will dominate the AI race.
