Gazing into crystal balls to advance understanding of crystal formation

Researchers at The University of Tokyo Institute of Industrial Science conducted simulations considering and neglecting hydrodynamic interactions to determine whether or not these interactions cause the large discrepancy observed between experimental and calculated nucleation rates for hard-sphere colloidal systems, which are used to model crystallization. The team obtained similar nucleation rate

Two closed ATP- and ADP-dependent conformations in yeast Hsp90 chaperone detected by Mn(II) EPR spectroscopic techniques [Biophysics and Computational Biology]

Hsp90 plays a central role in cell homeostasis by assisting folding and maturation of a large variety of clients. It is a homo-dimer, which functions via hydrolysis of ATP-coupled to conformational changes. Hsp90's conformational cycle in the absence of cochaperones is currently postulated as apo-Hsp90 being an ensemble of "open"/"closed"…

A well-designed machine could always hypothetically fake it. Photograph by Paul Biryukov / Shutterstock Someday, humanity might build conscious machines—machines that not only seem to think and feel, but re
