Matrix Stiffness Directs Stemness Signatures in Breast Cancer

Advanced Healthcare Materials, EarlyView.
We built lab‐grown breast cancer models to study how the stiffness of the tumor's surroundings influences cancer behavior. Softer environments encouraged more stem‐like, drug‐resistant cells, while stiffer ones kept cells more differentiated. These findings show that tissue mechanics drive cancer diversity and drug resistance, offering new insights for

Motor learning and neuroplasticity in humans [PDF]

, 2009
The central nervous system is plastic, in that the number and strength of synaptic connections changes over time. In the adult the most important driver of such changes is experience, in the form of learning and memory. There are thought to be a number

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, EarlyView.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Connectivity reflects coding: A model of voltage-based spike-timing-dependent-plasticity with homeostasis

, 2009
Electrophysiological connectivity patterns in cortex often show a few strong connections in a sea of weak connections. In some brain areas a large fraction of strong connections are bidirectional, in others they are mainly unidirectional.
