A Stanford team has revealed a new experiment where mice brains are partially replaced with human cells. The researchers genetically modified mice so their brains don’t fully develop, then injected human brain organoids.
The mice were tracked as they moved, with nearly half their brain volume replaced. This work could help study brain injuries but raises ethical questions about the limits of such experiments.
Climate tech innovators under 35: Shaping a sustainable future
MIT Technology Review has released its annual list of 35 Innovators Under 35, featuring nine individuals tackling climate and energy challenges. Their innovations include new lithium extraction methods, a furnace built to make steel cleaner and cheaper, and solid refrigerants that could cut energy consumption.
Climate tech innovations: Sustainable materials and energy efficiency
The innovators are also focusing on sustainable materials and energy efficiency. Projects include turning invasive weeds and food waste into useful materials and making AI more energy-efficient to address the growing energy demands of data centers.
AI Advances and Challenges Across Industries
AI is making significant strides in various sectors. Novo Nordisk will use Anthropic’s Claude AI for drug research, aiming to accelerate development. In cybersecurity, AI is powering a new generation of dating scams, with thousands catfished by AI-generated fake profiles. AI has also won a major forecasting contest, beating humans in predicting real events at the Metaculus Cup.
Regulatory efforts are evolving to address AI’s impact. US lawmakers passed a bill shifting grid costs to data centers to shield consumers from AI-driven energy price hikes. Globally, countries are diversifying AI investments by buying American chips and Chinese models. Google has been ordered to share more ad data with rivals and ensure compatibility with competing products.
In research, a new X-ray method allows faster deciphering of ancient scrolls. Additionally, digital twins of human organs are transforming medical treatment, with virtual replicas being used for patient care, surgery planning, and drug testing.
