...d protects the protein complexes from the layer of metal
that completes the sandwich. The researchers shone laser light on the device to create optical excitation, then measured the resulting current. "An important caveat is that we got very little current out, mostly because we had just a thin layer of ...
Sandia experiments may reduce possibility of future water wars
...ts growing in a series of plastic trays stacked on metal
racks, whenever a humidity sensor or a back-up timer trips a control circuit. To lessen labor and also protect against mold, the researchers are exploring the development and use of trays that themselves would be edible by livestock, thus making wash...
Optimizing protein's 'death domain' halts leukemia in laboratory study
...a pair of hydrocarbon subunits. Like a reinforcing metal
staple, Walensky explains, these links held the peptide in its natural coiled configuration. Further experiments confirmed that the stapled BH3 alpha helix retained its biological activity. In fact, it bound even more strongly to its target on the BC...

Innovative 'ceramic-on-metal' hip replacements to undergo clinical trials
...on 'metal-on-metal' as it generates ten times less metal
