Robotic Hair with Rich Sensation and Piloerection Functionalities Biomimicked by Stimuli‐Responsive Materials
- BiologyAdvanced Materials Technologies
A thin film composite comprising a transition metal oxide/hydroxide layer for sensation and high‐performing actuation under environmental stimuli including visible light, humidity, and temperature, and a graphene‐based layer for feedback strain sensing, is developed to demonstrate a “material intelligence” approach for robotics.

Visceral motor neuron diversity delineates a cellular basis for nipple- and pilo-erection muscle control
- BiologyNature Neuroscience
The results provide compelling evidence for a highly sophisticated organization of the sympathetic nervous system into discrete outflow channels that project to well-defined target tissues and offer mechanistic insight into how diversity and connectivity are established during development.
Hyperactivation of Sympathetic Nerves Drives Melanocyte Stem Cell Depletion
- Biology, MedicineNature
It is reported that, in mice, acute stress leads to hair greying through the fast depletion of melanocyte stem cells, and neuronal activity that is induced by acute stress can drive a rapid and permanent loss of somatic stem cells.

Hair cycle-dependent changes in adrenergic skin innervation, and hair growth modulation by adrenergic drugs.
- BiologyThe Journal of investigative dermatology
The observed hair cycle-dependent changes in adrenergic skin innervation, and hair growth modulation by isoproterenol, accompanied by changes in beta2-adrenoreceptor expression of selected regions of the hair follicle epithelium, further support the concept that bi-directional interactions between thehair follicle and its innervation play a part in hair growth control.
External light activates hair follicle stem cells through eyes via an ipRGC–SCN–sympathetic neural pathway
- BiologyProceedings of the National Academy of Sciences
It is shown that external light stimulation of animals’ eyes results in rapid activation of hair follicle stem cells with prominent hair regeneration via an ipRGC–suprachiasmatic nucleus–sympathetic nervous circuit.

Chronic variable stress activates hematopoietic stem cells
- Biology, MedicineNature Medicine
It is shown that stress increases proliferation of these most primitive hematopoietic progenitors, giving rise to higher levels of disease-promoting inflammatory leukocytes and monocytosis and neutrophilia in humans.
