SOLVENT EFFECT. “The sweetness of the two lowest concentrations of sucrose was significantly higher when dissolved in D2O compared to H2O.” https://lnkd.in/dzPDm5w View in LinkedIn

MOUSE TRIAL. “Next, we addressed the question whether the sweetness of D2O is perceived also by rodents. Lean mice of the C57BL/6J strain were drinking pure H2O, D2O, or a 43 mmol/l H2O sucrose solution for 16 h during a night period.” https://lnkd.in/dzPDm5w View in LinkedIn

CHOICE TEST. “Namely, each of the three groups of mice had a choice from two bottles containing (i) H2O and D2O, (ii) H2O and sucrose solution, or (iii) H2O and H2O (as a control). The food intake was unaffected in all groups (see SI, Figure S5 and Table S1).” https://lnkd.in/dzPDm5w View in LinkedIn

MOUSE DATA. “The results of the drinking experiments are presented in Fig. 3a–c, with a snapshot of the experimental setup shown in Fig. 3d. In cages where mice were offered both normal water and heavy water (Fig. 3a) consumption of D2O was within statistical error the same as that of H2O.” https://lnkd.in/dzPDm5w View in LinkedIn

AVOIDANCE. “Previous reports have shown that on longer timescales than those reported here mice learned to avoid D2O, as it is poisonous to them in larger quantities. It is not clear what is the cue that enables the avoidance learning, but it is evident that the early response to D2O is not attractive, suggesting that it is not eliciting sweet taste in mice.” https://lnkd.in/dzPDm5w View in LinkedIn

SO ENDS this first of two weekends on the taste of heavy water. “Less than a century ago, the discovery of the hydrogen isotope deuterium – 2H, but often simplified to D – revealed the existence of another kind of water with the chemical formula 2H2O or simply D2O. A typical hydrogen atom contains one proton within its nucleus. The deuterium isotope, however, has a neutron in addition to the proton, giving the hydrogen atom a greater mass. Hence, water formed with this type of heavy hydrogen is usually called... heavy water.” This has taste, very surprisingly. https://lnkd.in/dUTFQQG View in LinkedIn

QUANTUM NEURAL NETWORK. “The general message is that for gravity‐like synaptic connections in a quantum neural network the information storage mechanisms can become potentially richer than in more conventional approaches.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=nn-sqzr1LtkAAAAA%3Axz_GSzZ1qHcoqtsAnyUFHP7LE4hzmCqVF57CqUh5T7pkS8T48kTAc_oyaUb3Ticpy78QnB1xd9Jk4mw View in LinkedIn

ENHANCED NEURONS. “Instead of storing patterns in the local minima of the energy function, as, for example, in usual treatments of the Hopfield model, the enhanced memory points can be identified among the highly excited critical states, where set of neurons becomes gapless.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=nn-sqzr1LtkAAAAA%3Axz_GSzZ1qHcoqtsAnyUFHP7LE4hzmCqVF57CqUh5T7pkS8T48kTAc_oyaUb3Ticpy78QnB1xd9Jk4mw View in LinkedIn

NEURONS AND BLACK HOLES. “In this paper we shall attempt to take one more step and try to see if a neural network can possess some additional informational characteristics that are usually considered to be the defining properties of black holes.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=nn-sqzr1LtkAAAAA%3Axz_GSzZ1qHcoqtsAnyUFHP7LE4hzmCqVF57CqUh5T7pkS8T48kTAc_oyaUb3Ticpy78QnB1xd9Jk4mw View in LinkedIn
