Many of us use the phrase "it leaves a bad taste in your mouth" to express moral disgust, but findings in this new paper suggest that this metaphor may be even more fitting than previously thought! The authors of this thought-provoking paper, evaluated by Kent Berridge of the Neuroscience Faculty, find that moral outrage and a bad taste appear to activate the same facial muscles and produce the same expressions. Dr Berridge writes "A morally disgusting outcome may taste bad almost literally, according to this intriguing study. When presented with an unfair deal, people make faint versions of the same facial expressions that they show to an unpleasantly bitter or sour taste: wrinkling the nose and raising the upper lip." Kent explains "The authors suggest that their results support the hypothesis that moral disgust arose in human evolution from basic chemosensory affective precursors." He also expands on this to say_ "A corollary of that hypothesis is that moral disgust may recruit some of the same affective neural circuitry which generates oral disgust to avoid bitter or other unpalatable food, and which may have evolved originally for avoidance of poisonous foods."

A recent study by scientists in San Franscisco has used the cancer drug Herceptin to create an antibody that binds to a second antigen. Peter Colman of the Structural Biology Faculty, with W Douglas Fairlie, explains "This paper describes a procedure by which a monoclonal antibody directed at human epidermal growth factor receptor 2 (HER2) has been modified so as to acquire high affinity to a second antigen, vascular endothelial growth factor (VEGF), whilst retaining HER2 binding." Dominique Eladari of the ay) siology Faculty, with Bharath Wootla, tells us "Structural studies presented a large degree of homology between the two antigen-binding sites on the bH1 antibody. The authors, furthermore, elegantly demonstrate the positive pharmacological effect of the bi-specific antibody in an in vivo model, using an affinity- improved variant of bH1 (bH1-44)." Chemical Biology Faculty Member Carlos F Barbas believes "Two-in-one antibodies of the type developed by Fuh et al. and other bi- and multifunctional approaches will be key both in treating disease and in creating an affordable class of drugs in the future." EFTA00774615 Kermit Carraway of the Cell Biology Faculty goes on to explain "These antibody variants should provide excellent reagents for therapies of cancers that require HER2 and angiogenesis for tumor progression." It is obvious that this article has important implications for the development of future treatments for diseases such as cancer. The structure of Faculty of 1000 Biology makes it possible to identify papers of broad interest, irrespective of the journal in which they are published.

Christian tells us "This interesting paper suggests that nitrogen limitation may have influenced the DNA and amino-acid compositions of plant genomes and proteomes. This hypothesis relies on the observation that the transcribed plant genomes are nitrogen-poor when compared to the whole genome composition, whereas animal genomes and transcriptomes have almost the same N content." He found "The observation that a domesticated plant like rice has a significantly higher N content in the transcribed genome than Arabidopsis is quite interesting since, according to the authors, this could reflect the fact that rice was not (or less) N-limited through the domestication process, which could have relieved its genome from selection pressure."
