# chem: mimic a stable photosynthesis (inside a porous 'scaffold' to avoid deactivation / decomposition)

<< When molecules of cobalt oxide cubane, so named for its eight atoms forming a cube, are in solution, the catalytic units eventually collide into one another and react, and thus deactivate. To hold the catalysts in place, and prevent these collisions, the researchers used a metal-organic framework as a scaffold.  >>

<< Our study provides a clear, conceptual blueprint for engineering the next generation of energy-converting catalysts, >> T. Don Tilley

# brain: 'moral emotions' as a hypotetical diagnostic tool for dementia

AA << shows a particularly marked impairment of moral emotions in patients with frontotemporal dementia  >>

<< Frontotemporal dementia is a cognitive and behavioral disease caused by degenerative alteration of anterior regions of the brain. The disease is characterized by behavioral disorders such as a progressive apathy, loss of interest, social withdrawal, loss of inhibition and the processing of emotions. >>

AA << have known for a long time that these patients demonstrate impairment of emotion recognition and of theory of mind i.e. the ability to figure out the mental states of others: what they think, what they feel, what they like ... >>

<< Moral emotions can be defined as  "affective experiences promoting cooperation and group cohesion" including emotions such as admiration, shame or pity. >>

<< The results show that moral emotions are much more impaired than emotions without moral valence. In contrast, patients with Alzheimer's disease had no impairment as compared to healthy subjects and they had similar performance with moral and extra-moral emotions. >>

# ai: self-programming machines with twists, the beginning

<< Researchers have developed a flexible way of combining deep learning and symbolic reasoning to teach computers to write short computer programs. >>

<< A new program-writing AI, SketchAdapt, offers a way out. Trained on tens of thousands of program examples, SketchAdapt learns how to compose short, high-level programs, while letting a second set of algorithms find the right sub-programs to fill in the details. Unlike similar approaches for automated program-writing, SketchAdapt knows when to switch from statistical pattern-matching to a less efficient, but more versatile, symbolic reasoning mode to fill in the gaps. >>

<< Rather than rely on experts to define program structure, SketchAdapt figures it out using deep learning. The researchers also added a twist: When the neural networks are unsure of what code to place where, SketchAdapt is programmed to leave the spot blank for search algorithms to fill. >>

# phys: oscillating quasiparticles, decay and rebirth

<< Admittedly, quasiparticles do decay, however new, identical particle entities emerge from the debris," (..) If this decay proceeds very quickly, an inverse reaction will occur after a certain time and the debris will converge again. This process can recur endlessly and a sustained oscillation between decay and rebirth emerges. >> Ruben Verresen.

# gst: "diffusing wave paradox", synthetic microswimmers can mimic the behavior of Amoeba

<< Amoeba are unusual creatures that form when a dispersed population of cells spontaneously comes together and reorganizes itself into a multicellular macroscopic organism. To do this, a few leader cells emit chemical pulses that cause the other individual cells to move in the direction opposite to that of the traveling pulses (the "diffusing wave paradox," ), leading to the formation of dense clusters. >>

<< In experiments, the researchers used spherical particles that are half-coated by a carbon cap and placed in a viscous liquid. When illuminated by light, the particles propel themselves forward with the cap in front. >>

<< At low pulse speeds, the particles have enough time to reorient themselves, if needed, so that their caps are facing in the same direction as that of the traveling pulses. This orientation ensures that the particles travel in the same direction as the pulses. >>

<< At high pulse speeds, on the other hand, the pulses come too quickly for the particles to reorient themselves before the next one comes. This is because the speed of the particles' rotation is limited by the friction of the viscous liquid. So if the particles' caps are initially facing the oncoming pulses, the particles will move counter to the direction of the traveling pulses, resembling the behavior of amoeba in the diffusing wave paradox. >>
