Insights on cross-species transmission of SARS-CoV-2 from structural modeling.
PLoS computational biology
2020; 16 (12): e1008449
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the ongoing global pandemic that has infected more than 31 million people in more than 180 countries worldwide. Like other coronaviruses, SARS-CoV-2 is thought to have been transmitted to humans from wild animals. Given the scale and widespread geographical distribution of the current pandemic and confirmed cases of cross-species transmission, the question of the extent to which this transmission is possible emerges, as well as what molecular features distinguish susceptible from non-susceptible animal species. Here, we investigated the structural properties of several ACE2 orthologs bound to the SARS-CoV-2 spike protein. We found that species known not to be susceptible to SARS-CoV-2 infection have non-conservative mutations in several ACE2 amino acid residues that disrupt key polar and charged contacts with the viral spike protein. Our models also allow us to predict affinity-enhancing mutations that could be used to design ACE2 variants for therapeutic purposes. Finally, our study provides a blueprint for modeling viral-host protein interactions and highlights several important considerations when designing these computational studies and analyzing their results.

Synesthetic colors induced by graphemes that have not been consciously perceived
2015; 21 (2): 216-219
Grapheme-color synesthetes experience colors when they see printed letters of the alphabet. Currently, we tested four "projector" synesthetes, whose colors evoked by graphemes have sensory support or quale and appear to be restricted spatially to the letters like real colors. We use three different kinds of puzzle pictures that contained hidden letters, which require 30 s or more for nonsynesthetes to identify. Grapheme-color projector synesthetes recognize them three times faster and report that the colors were evoked before conscious letter recognition, clueing them as to what the letters were. Subjectively, the synesthetic subjects reported that they also saw mirror-reversed letters in the same colors as nonreversed letters which enabled them to read mirror-reversed text at thrice the normal speed. We conclude that in some synesthetes colors are evoked preconsciously early in sensory processing.

Interpolation of illusory pain in the human somatosensory system
2012; 41 (7): 878-880
Three coins are lined up with the middle coin at room temperature and flanking coins cooled down to 4 degrees C. If digits 2 and 4 are placed on the outer coins and digit 3 on the middle coin, the latter also feels cold; a striking example of perceptual filling in of temperature. We show that if digits 2 and 4 are placed on a thermal grill with alternating hot and cold bars, while digit 3 is placed on cardboard, the sensation of pain will also spread to the middle finger.

Graphemes evoke synesthetic colors even before they are consciously recognized
2011; 40 (4): 490-492
We showed a grapheme-color synesthete three different examples of stimuli in which the graphemes were 'hidden'--as in puzzle pictures--and became visible as letters only after prolonged viewing. Intriguingly the subject saw the appropriate colors accurately long before the graphemes became consciously visible--a novel form of blindsight.
