Redefining Matter | Why Matter Is Not What We Think It Is?

What is matter, really? Is matter an independent substance, or is reality fundamentally relational? In this episode, we explore some of the deepest questions in philosophy, metaphysics, and modern science, including Quantum Physics, Relativity, Quantum Field Theory, Dark Matter, Consciousness, Space, Time, Cosmology, and the Nature of Reality itself.

From atoms and particles to galaxies and the Universe, modern science increasingly points toward a world of processes, relationships, and dynamic structures rather than isolated objects. Could Matter and Consciousness be different expressions of the same underlying Reality? What can Systems Thinking, Complexity Theory, Nonduality, Taoism, Buddhism, and Vedanta contribute to our understanding of existence?

Let us examine the Nature of Matter, the mystery of Dark Matter, the meaning of Space-Time, and the interconnected fabric of the cosmos. This exploration may challenge the way you think about Reality, Existence, Consciousness, and your place within the Universe.

The Past, Present, & Future of Brain-Computer Interfaces By Rolando Masís-Obando

In brief: A historical look into how brain computer interfaces have transformed over the past few decades: the landmark research of the past, the landmark research of today, and how it’s going to transform the future of XR. As a neuroscientist for about a decade, my work has focused on how people represent spatial contexts, concepts, and events. I have been able to place people in VR experiences and then through the use of neuroimaging and AI methods untangle their thoughts and how those thoughts influenced what they remember. As this neuroimaging technology reduces in form-factor and increases in accessibility, we can no longer turn a blind-eye to how it may be used nefariously in consumer products. In this talk, I will describe how Brain-computer interfaces (BCIs) have been defined over the years, how research in this field has catapulted, an overview of the neuroscience behind the technology, the landmark studies of the past and present, use-cases in which XR, robotics, prosthetics and BCI have intertwined, and how new AI models are being used to perform mind-reading of both language and mental images. “With great power comes great responsibility” – I will end the talk by describing how and what it means for the future of XR and why it’s important to be careful with this technology, but also how incredibly empowering it can be for the future of XR.

Scientists Put a Fruit Fly’s Brain in a Computer Simulation… What It Did Is Now Scaring Scientists

Scientists have achieved an incredible breakthrough by recreating the brain of a fruit fly inside a computer simulation. By mapping around 140,000 neurons and millions of connections, they built a digital brain that can sense its environment, process information, and even control a virtual body. In the simulation, the digital fly was able to search for food, respond to stimuli, and show behaviors that were not directly programmed by scientists. This discovery shows how powerful neural connections are in generating behavior. It also raises fascinating questions about the nature of intelligence, consciousness, and whether complex brains—including ours—could one day be simulated in computers.

Harnessing the stem cell potential in the human hippocampus to limit cognitive aging

The field of human adult neurogenesis has been controversial despite mounting evidence. This Perspective proposes moving beyond debating the existence of adult neurogenesis, and towards discovering strategies to harness endogenous stem cell potential for resilience against cognitive aging.

Our brains may be automatically filtering out negative words

We tend to assume that emotionally charged words are more likely to grab our attention. An insult shouted across a crowded room or a disturbing phrase overheard on television can seem impossible to ignore. But a new study published in Psychological Science suggests the opposite may happen before words reach conscious awareness.

Researchers at the Hebrew University of Jerusalem found that when people were focused on a visual task, they were less likely to consciously notice negative spoken words than neutral ones. The findings offer new insight into how the brain determines which information enters conscious awareness and which remains outside it.

“This study is a nice example of how our conscious intuitions regarding what we notice are not always what our unconscious is doing,” said lead author Gal R. Chen, a doctoral candidate in psychology at the Hebrew University of Jerusalem.

LIS1 Is Critical for Axon Integrity in Adult Mice

Mutations in human LIS1 cause lissencephaly, a severe developmental brain malformation. Although most studies focus on development, LIS1 is also expressed in adult mouse tissues. We previously induced LIS1 knock-out (iKO) in adult mice using a Cre-Lox approach with an actin promoter driving CreERT2 expression. This proved to be rapidly lethal, with evidence pointing toward nervous system dysfunction. CreERT2 activity was observed in astrocytes, brainstem and spinal motor neurons, and axons and Schwann cells in the sciatic and phrenic nerves, suggesting dysfunctional cardiorespiratory and motor circuits. However, it is unclear how LIS1 knock-out in these different cell types contributes to the lethal phenotype.

Brain tumor map finds immune cell states that may predict meningioma recurrence

One of the most detailed maps to date of meningioma—the most common brain tumor in adults—reveals how the tumor’s surrounding environment helps drive disease behavior and patient outcomes, according to new research from Mayo Clinic.

The study, published in Nature Genetics and conducted in collaboration with scientists at Princess Margaret Cancer Center in Toronto, combines several advanced laboratory techniques to examine tumors at an unprecedented level of detail, offering clues to why some meningiomas grow slowly while others recur or become more aggressive. The findings could lead to more precise ways to predict risk and guide treatment decisions.

Growing evidence suggests that traditional grading systems for meningioma do not fully capture the behavior of these complex tumors, prompting the development of molecular classification tools that more accurately predict which tumors are more likely to recur after surgery.

Parkinson’s medication shows promise in treating treatment-resistant depression

For many people who suffer from depression, the condition is not just about feeling down but also about a loss of motivation and difficulty finding pleasure in activities they used to enjoy. A new study conducted in Sweden shows that a medicine used to treat Parkinson’s disease can be used as an add-on therapy to alleviate these symptoms in some patients with treatment-resistant depression. The study has been published in Nature Medicine.

The researchers at Lund University and the psychiatric services in Region Skåne have identified the potential new therapy for the condition associated with depression that involves a reduced ability to feel joy, pleasure or motivation—known as anhedonia. Those affected may lose interest in things that they previously found meaningful or rewarding.

The study is an example of what is known as drug repurposing, whereby an already approved medicine is used to treat a different condition. In this study, the researchers investigated pramipexole, which has long been used to treat Parkinson’s disease, as an add-on therapy for depression with marked anhedonia.
