Nature-inspired precisely assembled nanotubes

A new design principle for building nanostructures for filtration and desalination
March 28, 2016

Precision meets nano-construction, as seen in this illustration. Berkeley Lab scientists discovered a peptoid composed of two chemically distinct blocks (shown in orange and blue) that assembles itself into nanotubes with uniform diameters. (credit: Berkeley Lab)

Optogenetics modulation of membrane voltage to control induced tumor-like structures. (Top) Tumor induced in tadpole embryo. (Bottom left) Control embryo not injected with light-sensitive protein is highly fluorescent, indicating relative depolarization. (Bottom right) Embryo injected with light-sensitive protein, causing hyperpolarization and significantly lowering the incidence of tumor formation. Scale bar = 150 micrometers. (credit: Brook T.

New type of molecular tag makes MRI 10,000 times more sensitive

Could detect biochemical processes in opaque tissue without requiring PET radiation or CT x-rays
March 25, 2016

Duke scientists have discovered a new class of inexpensive and long-lived molecular tags that enhance MRI signals by 10,000-fold. To activate the tags, the researchers mix them with a newly developed catalyst (center) and a special form of hydrogen (gray), converting them into long-lived magnetic resonance “lightbulbs” that might be used to track disease metabolism in real time.

In this time-lapse series of photos, progressing from top to bottom, a coating of sucrose (ordinary sugar) over a wire made of carbon nanotubes is lit at the left end, and burns from one end to the other. As it heats the wire, it drives a wave of electrons along with it, thus converting the heat into electricity. (credit: MIT)
