Quantum transducers will allow application-specific quantum hardware to accelerate the realization of large scale networks of entangled qubits.

Lentiviral vectors have been used for gene therapy in the clinical phase in recent years. These vectors provide a tool for gene insertion, deletion, or modification in organisms.

Two-component signal transduction systems enable bacteria to sense, respond, and adapt to a wide range of environments, stressors, and growth conditions. Signal transduction can occur through the transfer of phosphoryl groups from adenosine triphosphate ( atp ) to a specific histidine residue in the histidine kinases (hk).
Transduction is the conversion of a signal into a cellular response. Transduction occurs in one step but the majority of the time it takes multiple changes. These multiple steps are called the signal transduction pathway. The signal transduction pathway is when a small collection of signal molecules produce a large response across the cell.
This is a tale of how technology drove the discovery of the molecular basis for signal transduction in the initiation of sporulation in and in bacterial two-component systems.

Increased transduction efficiency of tyrosine-mutant vectors is due to lack of capsid ubiquitination and improved intracellular traf-ficking to the nucleus. These studies have led to the development of aav vectors that are capable of high-efficiency transduction at lower doses, which has important implications in their use in human gene therapy.
Both in situ electroporation and retroviral transduction may be used to target early hematopoietic precursors, but the latter appears more convenient if a large pool of stably transduced cells is required. We discuss the assets and limitation of both methods, which may be alternatively chosen depending on scientific constraints.
