Stanford School of Medicine researchers report that the human brain forms from two separate types of stem cells rather than one uniform source. One lineage, marked by the Otx2 gene, produces the midbrain and forebrain responsible for higher-order thinking and speech, while a distinct stem cell type gives rise to the hindbrain, which governs basic functions like heartbeat and breathing. Researcher Kyle Loh says this finding allows scientists to grow hindbrain neurons in a lab dish for the first time.

A research team created their own burned, rolled-up papyrus scrolls and found they could read the hidden text by using X-ray computed tomography and X-ray fluorescence to detect lead in the ink, rather than relying on carbon detection alone. The method allowed them to virtually unroll the scrolls and clearly view writing that previous X-ray CT techniques could not distinguish from the carbon-based papyrus itself. The findings are published in PLoS ONE.

A Nature Index 2026 feature on regenerative medicine reviews progress in cell therapy and tissue engineering, including the use of induced pluripotent stem cells (iPSCs) to pursue treatments for autoimmune diseases, Parkinson's disease and heart failure. It also notes clinical trials using stem-cell transplants to replace insulin-producing cells in people with type 1 diabetes have shown some success.

Researchers led by immunologist Hongkui Deng at Peking University transplanted lab-grown pancreatic islet cells, derived from a patient's own reprogrammed fat cells, into a young woman with type 1 diabetes. Nearly three years after the 2024 procedure, she no longer requires insulin injections and reports stable blood-sugar levels.

Stanford Medicine researchers discovered that the human brain is actually built from two distinct developmental lineages: a hindbrain system controlling breathing and heartbeat, and a forebrain/midbrain system responsible for higher cognition. The team found these two regions arise from separate progenitor pathways rather than one branching from the other, and used this insight to finally grow functional hindbrain motor neurons from human stem cells in the lab. They also traced this dual-origin pattern back over 550 million years, finding it in chickens, zebrafish, and acorn worms.

Researchers led by Kyle Loh at Stanford Medicine discovered that the forebrain and hindbrain arise from distinct progenitor cells rather than a single common origin, contradicting decades of neuroscience theory. The forebrain governs higher cognition like language and abstract thought, while the hindbrain controls vital functions such as heartbeat and breathing. The study, published in Nature Neuroscience, was co-led by graduate students Carolyn Dundes and Rayyan Jokhai.

IEEE is launching its inaugural International Leadership Conference on October 3-4 in Budapest, aimed at helping senior technical professionals transition into leadership roles. The event centers on the concept of 'legacy leadership,' which redefines success as mentoring others and transferring knowledge rather than personal technical achievement. Registration for the conference is currently open.

Researchers at Stanford, led by Kyle Loh, report evidence that the brain develops from two separate populations of precursor cells rather than a single universal one. One lineage forms the hindbrain, which governs vital functions like heartbeat and breathing, while a second gives rise to both the forebrain and midbrain. The findings, published in Nature Neuroscience, also describe a method for converting stem cells efficiently into hindbrain motor neurons.

A Stanford research team removed a large section of a mouse's brain and replaced it with tissue grown from human stem cells known as brain organoids. The goal was to give these lab-grown clusters of neurons a living, connected environment closer to an actual brain than a petri dish can offer.

A Stanford team led by Sergiu Pașca genetically engineered mice to lack most of their cortex and hippocampus, then implanted human brain organoid cells into the resulting gap. The human cells expanded to fill much of that space within weeks to months, and mice with the human tissue performed better on memory maze tests than mice without it.

Researchers report interim results from the ongoing Algonquin study, a multicentre, open-label trial evaluating a BPd drug combination in patients with relapsed or refractory multiple myeloma. The analysis covers patients enrolled in the trial's second phase, with data collected through late October 2025 after enrollment closed in September 2022. Eligible patients had failed prior treatments including lenalidomide and proteasome inhibitors, but had not previously received pomalidomide or BCMA-targeted therapy.

Academa is a new project that treats lecture videos like software: instructors describe what a teacher says and draws using a code-like script, which a compiler then renders into a video with text-to-speech narration and generated graphics. Because the lecture exists as editable source rather than a finished video file, mistakes can be patched and new versions shipped, much like updating a codebase. The team is now applying large language models to this text-based format, aiming to let AI generate or refine entire STEM lectures automatically.
