Remembering past events in minute detail, revisiting them methodically, and reliving past emotions—this is the peculiarity of people with an exceptional memory of their own lives, known as autobiographical hypermnesia, or hyperthymesia. This fascinating condition remains poorly understood, and each new case contributes to our understanding.
In an article in Neurocase, researchers from Paris Brain Institute and the Memory, Brain, and Cognition Laboratory describe the extraordinary mental life of a 17-year-old girl.
Autobiographical memory refers to our ability to remember experiences that have shaped our lives since childhood. It consists of emotional and sensory memories of places, moments, and people, as well as a set of factual information—such as names and dates—that allows us to orient ourselves when we try to recall an episode from the past.
In the subatomic universe of quantum physics, you can achieve things considered impossible in our flesh-and-blood physical world. Things like superposition, entanglement, and even teleportation all seem possible when things go quantum. Now, scientists from the Austrian Academy of Sciences (ÖAW) and University of Vienna are adding a kind of time travel to the list.
In a series of papers published on preprint servers and in various online journals (including Optica, arXiv, and Quantum), researchers including ÖAW’s Miguel Navascués and University of Vienna’s Philip Walther explain the possibility of speeding up, slowing down, and even reversing the flow of time within a quantum system.
Several studies have indicated that forgotten memories may not be as irretrievable as once thought. Memory appears to be closely tied to the context in which it was encoded. Consequently, remembering smells, sounds and other environmental cues, as well as any feelings experienced during the time the memory was formed can help to recall the memory. However, these memory studies have not sufficiently determined how this kind of contextual memory recall is forgotten after recall.
As most people are aware, retrieving a memory normally becomes more and more difficult as time goes on, but the rate of forgetting actually declines over time in a nonlinear manner due to ongoing memory consolidation. In other words, humans will forget an event at a faster rate within the first few days or weeks, and then the forgetting levels off somewhat and less of the memory is lost over longer time periods.
In a new study, published in the Proceedings of the National Academy of Sciences, a group of German scientists sought to determine if retrieving memories with “mental time travel” can restore the retrieval and forgetting rate to how they were shortly after encoding. To do this, they recruited 1,216 participants to undergo two different memory experiments.

What is time? Speaking time travel, black holes and the remits of science. In this podcast conversation, we speak with Professor David Wilkinson — physicist and author of popular science books on Stephen Hawking to explore the question: can we ever fully understand time through science, or does it open up more mystery?
This Deep Dive AI podcast discusses my book The Physics of Time: D-Theory of Time & Temporal Mechanics, an insightful exploration into one of the most profound mysteries of existence: the nature of time. As part of the Science and Philosophy of Information series, this book presents a radical reinterpretation of time grounded in modern physics and digital philosophy. It questions whether time is a fundamental aspect of reality or an emergent property of consciousness and information processing. Drawing on quantum physics, cosmology, and consciousness studies, this work invites readers (and listeners) to reimagine time not as a linear, absolute entity, but as a dynamic, editable dimension intertwined with the fabric of reality itself. It challenges traditional views, blending scientific inquiry with metaphysical insights, aimed at both the curious mind and the philosophical seeker.
In this episode, we dive deep into The Physics of Time: D-Theory of Time & Temporal Mechanics by futurist-philosopher Alex M. Vikoulov. Explore the profound questions at the intersection of consciousness, quantum and digital physics, and the true nature of time. Is time fundamental or emergent? Can we travel through it? What is Digital Presentism?
The Physics of Time: D-Theory of Time & Temporal Mechanics by Alex M. Vikoulov is an insightful exploration into one of the most profound mysteries of existence: the nature of time. As part of the Science and Philosophy of Information series, this book presents a radical reinterpretation of time grounded in modern physics and digital philosophy. It questions whether time is a fundamental aspect of reality or an emergent property of consciousness and information processing.
The book introduces the D-Theory of Time, or Digital Presentism, which suggests that all moments exist as discrete, informational states, and that our perception of time’s flow is a mental construct. Vikoulov explores theoretical models of time travel, the feasibility of manipulating time, and the concept of the Temporal Singularity, a proposed point where temporal mechanics may reach a transformative threshold.
Researchers from the International Institute of Molecular and Cell Biology in Warsaw (IIMCB) have described a new mechanism that improves the efficiency of mRNA-based therapies. The research findings could facilitate the development of novel therapeutics against cancers and infectious diseases.
The scientific experiments were carried out at IIMCB, but important contributions also came from collaborators at the Faculty of Physics and Faculty of Biology of the University of Warsaw, the Medical University of Warsaw, and the Institute of Biochemistry and Biophysics of the Polish Academy of Sciences. The study by the Polish researchers has just been published in Nature.
“mRNA vaccines played a key role in controlling the spread of the pandemic. However, mRNA itself is an exceptionally unstable molecule. This does not affect the safety of the therapy but limits its effectiveness—for example, by shortening the duration of action. A particularly important role in mRNA stability is played by its so-called poly(A) tail. In our research, we examined these limitations,” says Prof. Andrzej Dziembowski from the Laboratory of RNA Biology—ERA Chairs Group at the International Institute of Molecular and Cell Biology in Warsaw, one of the lead authors of the study.
