Gene Therapy without using viruses to get genes to cells

Gene Therapy goal: deliver desired genes to cells to either cure disease or improve body functions such as stronger muscles. Gene therapy has the potential to enhance human performance and cure diseases. Problem: Viruses used for gene delivery occasionally cause severe immune responses. The novel lipid molecule created at UC Santa Barbara has a tree-shaped, …

Combination Molecular machine created

This is progress achieved via advanced chemistry towards more complex molecular machinery. A pair of light activated molecular pliers has been joined to a pair molecular flippersThe result is the first example of one molecular machine controllably driving the action of another, say the researchers. “The next step is to integrate multiple molecular machines” into …

Other tech: Fast communications – optical/wireless

Telecommunications researchers have demonstrated a novel communications network design that would provide both ultra-high-speed wireless and wired access services from the same signals carried on a single optical fiber. The system could provide 32 different channels, each providing 2.5 gigabit-per-second service. That capacity is already working in the lab. Using a technique developed at Georgia …

nanoscale technology: Artificial muscle advance

Researchers at the University of Dallas have created alcohol- and hydrogen-powered artificial muscles that are 100 times stronger than natural muscles, able to do 100 times greater work per cycle and produce, at reduced strengths, larger contractions than natural muscles. Among other possibilities, these muscles could enable fuel-powered artificial limbs, “smart skins” and morphing structures …
