Date: October 2, 2026cells appear to have an unexpected “energy addiction,” relying far more heavily than healthy blood-forming cells on a molecule called NAD. Disrupting this energy pathway selectively weakened the cancer-driving cells, revealing a potential new target for treatment. Share: FULL STORY

Date: September 28, 2026 stem cell that appears to serve as a master spinal stenosis, these cells become unusually active and may drive the ligament overgrowth that squeezes spinal nerves and causes pain, numbness, and difficulty walking. Researchers found that reducing calcium signaling stopped this abnormal growth in mice. Share: FULL STORY

Date: September 21, 2026egenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.

Date: September 18, 2026 a population of cells that can start the process of programmed cell death, survive it, and then help rapidly rebuild damaged tissue. Their descendants become far more resistant to future damage, revealing a mechanism that could improve healing but may also help cancers return after treatment. Share: FULL STORY
