Scientists have discovered that E-cadherin, a protein best known as the “glue” holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, researchers found that cells can dramatically reshape their lower surfaces to engulf cellular debris while keeping their upper surfaces stable, allowing protective barriers to remain sealed.

Scientists just pushed superconductors beyond their usual current limit
Ultrashort electrical pulses allowed scientists to push superconductors closer than ever to the point where their electron pairs actually break apart. The method revealed hidden differences between superconducting materials and could open new ways to probe and control their quant

Scientists may have found a “unifying theory” of chronic fatigue
Scientists found that five seemingly unrelated conditions, including long Covid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings could help explain their shared symptoms and may open the door t
