Recombinant clathrin protein fragments form assemblies that template gold nanocrystals in an array across the latticed surface. The nanocrystals exhibit unusual anisotropic morphologies with long range ordering, both of which are dependent upon the presence of a hexahistidine tag on the clathrin heavy chain fragments.

Popper commanded international audiences and conversation with him was an intellectual adventure even if a little rough animated by a myriad of philosophical problems. His intense desire to tear away at the veneer of falsity in pursuit of the truth lead him to contribute to a field of thought encompassing (among others) political theory, quantum mechanics, logic, scientific method and evolution...

Starting from the 15 century in the Atlantic slave trade, black people have been treated by lighter-skinned counterparts as commodities to be sold and bought. The effects of the trade and the resulting dehumanization can still be seen in subsequent historical events and in today’s society. Analyzing the Haitian Revolution in the late 18 century through literature such as The Grateful Negro by M...

In his writings and actions, Sir William Osler betrayed no evidence of anti-Semitism. In his era, this trait was unusual. Two of his articles, "Letter from Berlin" and "Israel and medicine," dealt directly with his thoughts on the Jewish people. In both he spoke out against anti-Semitism. Osler had friendships with Jewish colleagues--an example is the great regard in which he held US pediatrici...

Pan–tilt–zoom (PTZ) camera networks have an important role in surveillance systems. They have the ability to direct the attention to interesting events that occur in the scene. One method to achieve such behavior is to use a process known as sensor slaving: one (or more) master camera monitors a wide area and tracks moving targets so as to provide the positional information to one (or more) sla...

Label-free detection of the interaction between hexahistidine-tagged human κ-opioid receptor membrane protein and anti-His antibody is demonstrated in liquid by an optical microelectromechanical system utilizing electromagnetically actuated microresonators. Shift in resonance frequency due to accretion of mass on the sensitive surface of microresonators is monitored via an integrated optical re...

We evaluate the ability of hexahistidine (His6) tags on peptide and protein substrates to recruit deoxyribozymes for modifying those substrates. For two different deoxyribozymes, one that creates tyrosine-RNA nucleopeptides and another that phosphorylates tyrosine side chains, we find substantial improvements in yield, kobs, and Km for peptide substrates due to recruiting by His6/Cu(2+). Howeve...
