Why dolphins swim so fast: The secrets of hidden whirlpools

Dolphins are famous for their speed and agility in the water, but what exactly allows them to swim so effectively? Scientists have been asking this question for years, hoping to learn how to optimize propulsion in fluids from these elegant creatures.

When a dolphin swims, it flaps its tail up and down in a kicking motion. This motion pushes water backward, generating a turbulent flow filled with swirling currents of many different sizes. Until now, it has been difficult to determine how these complex motions conspire to propel the dolphin forward.

Pasó con la llegada del sonido, el color y los efectos especiales por computadora (CGI). Hoy estamos viviendo ese mismo salto histórico gracias a la inteligencia artificial.

Lo divertido es que, en lugar de un drama profundo, lo primero que alguien decidió crear con este inmenso poder fue a Stephen Hawking en una silla de ruedas con láseres peleando contra Neil deGrasse Tyson por el control del multiverso. Los grandes cineastas de la historia estarían orgullosos… probablemente.

Realization experiences: a convergent account of insight and mystical experiences

We argue that the powerful transformative effects of mystical-type experiences can be understood using the same machinery that underlies insight problem solving, and that both mystical experiences and insight are species of a genus of “realization experiences”: experiences wherein some phenomenon or piece of information becomes suddenly experienced as real or true. Specifically, we argue that understanding both in this way allows us to model mystical experiences through the same combination of behavioral entropy and graph theory that have successfully been used to model insight problem solving. Starting from tension between novel information and prior representations, the agent destabilizes its representational network to allow it to enter a state of altered salience and enhanced associations to update the network.

Application of the Theory of Constraints to Radiology

Radiology throughput isn’t about doing more; it’s about fixing the bottleneck. Apply the Theory of Constraints to the imaging workflow to identify true rate-limiters and target high-impact process improvements in a resource-strained environment.


Applying the theory of constraints to the radiology workflow allows identification of constraints for more targeted and higher-yield process improvement projects to increase system throughput.

Applications of Spatial Transcriptomics in Ischemic Stroke Research

Acute ischemic stroke is a complex disorder in which the damage goes beyond neuronal loss and involves dynamic responses from glial, vascular, stromal, and immune cells. Spatial transcriptomics (ST) has become a powerful tool to study these processes by preserving tissue architecture while revealing detailed gene expression patterns. This review describes how ST has advanced the understanding of cellular changes after stroke, focusing on microglia, astrocytes, and oligodendrocytes to showcase the complexity of stroke pathobiology.
