Northwestern University engineers printed artificial neurons that successfully triggered responses in living mouse brain tissue, a federal executive order directed the FDA to accelerate review of psychedelic therapies, and Cerebras Systems filed for an IPO on $510 million in revenue with over $10 billion in combined deals from AWS and OpenAI.

Researchers at Northwestern created artificial neurons from nanoscale flakes of molybdenum disulfide and graphene, printed onto flexible polymer surfaces, that generate the full range of biological neural signaling - single spikes, continuous firing, bursting patterns. When placed against slices of mouse brain tissue, the synthetic devices triggered real neurons. The biological tissue responded to them as if they were native. The implications run from neuroprosthetics and brain-machine interfaces to computing architectures that operate at five orders of magnitude less energy than silicon. The boundary between electronic and biological intelligence narrowed measurably in a single experiment.

A University of Pittsburgh clinical trial published in Nature Communications demonstrated that regulatory dendritic cell therapy enabled three liver transplant recipients to stop immunosuppressant drugs entirely for at least three years. The body already possesses the machinery for organ tolerance - the breakthrough is learning how to activate it deliberately. Meanwhile, an executive order signed yesterday directed the FDA to expedite review of psychedelics already designated as breakthrough therapy drugs, with $50 million in federal research funding and three priority review vouchers expected next week. Decades of institutional resistance to accumulating clinical evidence are being compressed into months.

Cerebras Systems filed for IPO after reporting $510 million in 2025 revenue and securing partnerships with AWS and OpenAI worth over $10 billion combined. CEO Andrew Feldman said Cerebras took the “fast inference business at OpenAI” from Nvidia. The filing arrives alongside a global RAM shortage - production meeting only 60% of projected demand - that is constraining the physical infrastructure of the intelligence era even as demand accelerates. In industrial electrification, Lloyds Metals converted a 650-ton Liebherr mining excavator from diesel to electric using its own engineering teams, and UK data showed the average new EV now costs £785 less than the average petrol car. JinkoSolar published perovskite-silicon tandem cells at 32.76% certified efficiency on industrial substrates, pushing the technology from laboratory to production scale.
