New surgical strategy offers hope for repairing spinal injuries
Both ventral and dorsal roots have been detached, which is the common scenario clinically, the ventral root is implanted directly into the cord as...
Significant ongoing decline in sperm counts of Western men
A rigorous and comprehensive meta-analysis of data collected between 1973 and 2011 finds that among men from Western countries, sperm concentration declined by more...
Potential for synthetic materials systems that can ‘count’ and sense their...
Modeled microcapsules demonstrate 'quorum sensing' behavior. A small collection of microcapsules remains dormant (left) whereas a large, crowded population exhibits oscillations in chemical activity...
Involvement of prescription opioids in fatal car crashes climbs sevenfold
The prevalence of prescription opioids increased from 0.9 percent during 1995-1999 to 5.2 percent during 2010-2015 in male drivers, and from 1.4 percent to...

Artificial muscle for soft robotics: Low voltage, high hopes
An artificial muscle built from a sandwich of soft, stretchable elastomers and carbon nanotubes electrodes. This type of actuator could be used in everything...
Somersaulting simulation for jumping bots
A simulation (top row) and real-world experiment (bottom row) match for the same jumping mechanism designed to flip over a wall and land right...
Gene transfer corrects severe muscle defects in mice with Duchenne muscular...
This photograph shows how AAV micro-dystrophin gene therapy ameliorates dystrophic pathology in skeletal muscle. Blue color in Masson trichrome staining indicates fibrosis. Dark red...
Soft-bodied robots: Actuators inspired by muscle
VAMPs are shown actuated and cut open in cross section. The cross section shows the inner chambers that collapse when vacuum is applied.
