Dragline spider silk is known for its combination of strength and toughness, but this combination has been hard to replicate in synthetic fibers. Liao et al. electrospun polyacrylonitrile- co -methyl acrylate fibers modified with a small amount of poly(ethylene glycol) bisazide (PEG-BA) (see the Perspective by Fox). After collecting the electrospun yarn, it was annealed under tension that both…
We designed a single-piece 3D-printable, parametric, anatomical robotic hand and captured diverse manipulation behaviors.
“No student should have to choose between financial survival and medical care,” this researcher writes
Epithelial stretching promotes the release of EGF receptor ligands that stimulate ERK activation.

A continuously operating wearable powers and exchanges data with osseosurface electronics to measure fracture recovery.
What circumstances might justify deliberate, full extinction of a species?
Dysregulated T cells and progenitors with lymphoma driver mutations are enriched in duodenal biopsies from patients with refractory celiac disease.
Mountain biodiversity reorganizes rapidly as species shift upslope to track temperatures. Pervasive species redistribution poses substantial threats to mountain ecosystems, a phenomenon sometimes described as…
