<< Tourists at the Koorana Saltwater Crocodile Farm in Coowonga, Queensland, Australia (..) were randomly assigned to play a laptop-simulated Electronic Gaming Machine (EGM) either: (1) prior to entry, or (2) after having held a 1-m saltwater-crocodile >>

<< At-risk gamblers with few self-reported negative emotions placed higher average bets at the EGM after having held the crocodile when compared to the control >>

<< high arousal can intensify gambling in at-risk players, but only if this feeling state is not perceived as a negative emotion >>

# age: autophagy inactivation (e.g. in neurons) to reverse the effects of age (50% extension of life) in the whole old body (post-reproductive C. elegans)

AA << identified that the inactivation of genes governing the early stages of autophagy up until the stage of vesicle nucleation, such as bec-1, strongly extend both life span and health span >>

AA << demonstrate that the improvements in health and longevity are mediated through the neurons, resulting in reduced neurodegeneration and sarcopenia >>

AA << propose that autophagy switches from advantageous to harmful in the context of an age-associated dysfunction >>

# gene-evol: behind interactions among organisms: causality more than just correlation

<< Organisms engage in extensive cross-species molecular dialog, yet the underlying molecular actors are known for only a few interactions >>

AA << developed an expression quantitative trait locus (eQTL) mapping-based approach to identify cause-and-effect relationships between genes from two partners engaged in an interspecific interaction >>

<< In a first-of-its-kind study, NC State researchers applied a new approach to examine how members of two different species – a plant and a pathogen, for example, or a bacterium and a human – interact at the molecular level, and whether slight genetic changes in one species could affect gene expression in the other >>

<< "We're really trying to get to the genetics behind the interactions between two different organisms," said David McK. Bird [..] "Genetics gives us causality more than just correlation." >>

AA << introduce the flip-flop qubit, a combination of the electron-nuclear spin states of a phosphorus donor that can be controlled by microwave electric fields >>

<< to encode quantum information in the electron-nuclear spin states of 31P [phosphorus] donors in silicon, and to realize fast, high-fidelity, electrically driven universal quantum gates >>

<< a credible pathway to the construction of a large-scale quantum processor, where atomic-size spin qubits are integrated with silicon nanoelectronic devices, in a platform that does not require atomic-scale precision in the qubit placement [..] and, with realistic assumptions on noise and imperfections, are predicted to achieve error rates compatible with fault-tolerant quantum error correction >>

<< a new way to define a 'spin qubit' that uses both the electron and the nucleus of the atom. Crucially, this new qubit can be controlled using electric signals, instead of magnetic ones. Electric signals are significantly easier to distribute and localise within an electronic chip >>
