Skeletal muscle is widely perceived as nearly incompressible despite the fact that blood and lymphatic vessels within the endomysial and perimysial spaces undergo significant changes in diameter and length during stretch and contraction. These fluid shifts between fascicle and interstitial compartments have proved extremely difficult to measure.
The use of synthetic biological systems in research, healthcare, and manufacturing often requires autonomous history-dependent behavior and therefore some form of engineered biological memory. For example, the study or reprogramming of aging, cancer, or development would benefit from genetically encoded counters capable of recording up to several hundred cell division or differentiation events.
Noble metals such as gold and silver are conventionally used as the primary plasmonic building blocks of optical metamaterials.
Otitis media (OM), a middle-ear infection, is the most common childhood illness treated by pediatricians. If inadequately treated, OM can result in long-term chronic problems persisting into adulthood. Children with chronic OM or recurrent OM often have conductive hearing loss and communication difficulties and require surgical treatment.
Microvascular networks support metabolic activity and define microenvironmental conditions within tissues in health and pathology. Recapitulation of functional microvascular structures in vitro could provide a platform for the study of complex vascular phenomena, including angiogenesis and thrombosis.
Direct electric measurement via small contacting pads on individual quasi-one-dimensional nanoentities, such as nanowires and carbon nanotubes, are usually required to access its electronic properties. We show in this work that 1D nanoentities in suspension can be driven to rotation by AC electric fields.
In this article, we propose a Flexure-FET (flexure sensitive field effect transistor) ultrasensitive biosensor that utilizes the nonlinear electromechanical coupling to overcome the fundamental sensitivity limits of classical electrical or mechanical nanoscale biosensors.
FOR the past few years, a European collaboration called IMPLICC (Implications and Risks of Novel Options to Limit Climate Change) has been looking at what it might mean to engineer the climate, by reducing the amount of sunshine that reaches the Earth’s surface. A lot of IMPLICC’s work, like much else in climate science, has taken the form of computer modelling.
Unmanned Aerial Vehicles, more commonly known as drones — the same basic technology used to hunt al Qaeda in Afghanistan — are increasingly being flown in American airspace.
Republicans rejected the proposal in a special legislative session.
