# brain: negative emotional contagion and cognitive bias (in ravens, Corvus corax).

<< after witnessing a conspecific in a negative state, ravens perform in a negatively biased manner on a judgment task. >>

AA << findings thus suggest negative emotional contagion in ravens, and in turn advance our understanding of the evolution of empathy. >>

# phys: it could be used to completely remove all noise from a noisy channel

AA << have proposed a second level of quantization, in which both the information carriers and the channels can be in quantum superposition. In this new paradigm of communication, the information carriers can travel through multiple channels simultaneously. >>

AA << formulated a quantum communications model that can be used to compute the amount of information that can be reliably transmitted when using a given number of channels in a quantum superposition. (..) for certain types of noise, the superposition of channels, along with the ability to switch a channel with itself, could be used to completely remove all noise. This opens up the possibility of obtaining perfect quantum communication in a noisy channel. >>

# ai: apropos of black box approach in machine learning algorithms

<< A black box is a machine learning program that does not explain how it reaches its conclusions, either because it is too complicated for a human to understand or because its inner workings are proprietary. In response to concerns that these types of models may include unjust inner workings—such as racism—another growing trend is to create additional models to "explain" these black boxes. >>

<<  Even when so-called explanation models are created, (..) decision-makers should be opting for interpretable models, which are completely transparent and easily understood by its users. >>

# behav: intriguing wolves, prosociality among wolves (compared to dogs)

<<  Prosociality is important for initiating cooperation. (..) In a prosocial choice task, wolves acted prosocially to in-group partners; providing significantly more food to a pack-member compared to a control where the partner had no access to the food. Dogs did not. Additionally, wolves did not show a prosocial response to non-pack members, in line with previous research that social relationships are important for prosociality.  >>

# tech: apropos of peripheral neural interfaces; the AlterEgo 'second self'

<< AlterEgo is a  non-invasive, wearable, peripheral neural interface that allows humans to converse in natural language with machines, artificial intelligence assistants, services, and other people without any voice-without opening their mouth, and without externally observable movements-simply by articulating words internally. >>

<< AlterEgo seeks to combine humans and computers—such that computing, the Internet, and AI would weave into human personality as an internal "second self" and augment human cognition and abilities. >>
