To keep our bodies properly oriented, our brains perform impressive feats of calculation that track our stumbling meat sack through a mental map of our surrounds.

While a lot of research has focussed on the mapping, little has managed to determine how our neurological wiring monitors our direction within it.

A team of researchers from the University of Birmingham in the UK and the Ludwig Maximilian University of Munich in Germany has identified signature brain activity that describes a kind of ‘neural compass’ in the hope of understanding how we find our way through the world.

Futurists, including some medical doctors, are signing up to be decapitated—and then have their brains frozen. But without a body, what will their minds become?

Researchers show that the possible cause of local bone erosion in cholesteatomas are fibroblasts from the bone that express a protein called activin A.

Chronic inflammation of the middle ear can cause several problems and complications that can affect a person’s hearing and balance. One such problem is the formation of a cholesteatoma, which is an abnormal collection of cells in the ear that can cause bone erosion if left untreated. In turn, this can cause symptoms such as hearing loss, dizziness, facial paralysis, and even a brain infection.

In a study published in the journal Nature Communications, researchers from Osaka University have revealed the cause of cholesteatomas, which may help in developing new therapies for patients who are suffering from this disease.

U.S. strategists must take heed of this important domain.

Reflections on a philosopher who believed we can solve the problem of consciousness.

Often perceived as abstract and challenging, physics covers fundamental aspects of the universe, from the tiny world of quantum mechanics to the vast cosmos of general relativity. However, it often comes with intricate mathematical formulations that intimidate many learners. Visual Intuitive Physics is an emerging field that seeks to transform this complexity into accessible visual experiences, making physics more tangible and relatable. By employing visual aids and intuitive methodologies, this approach enhances the understanding of physical principles for students, researchers, and enthusiasts.

Understanding complex physics concepts often requires intuitive visualization that transcends verbal and mathematical explanations. Visualization in physics involves using graphs, diagrams, simulations, and other visual tools to provide a tangible understanding of abstract concepts. For instance, Marr and Bruce emphasized that visual tools significantly enhance conceptual understanding in students by providing concrete ways to comprehend physical laws.

Visualization helps bridge the gap between theoretical concepts and practical understanding. Per Kozma and Russell, visualization is pivotal in building cognitive structures that make understanding and remembering scientific principles easier. This is particularly significant for concepts that lack direct physical analogs, such as quantum mechanics and relativity.

Researchers at Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine have developed a nanoparticle that can penetrate the blood-brain barrier. Their goal is to kill primary breast cancer tumors and brain metastases in one treatment, and their research shows the method can shrink breast and brain tumors in laboratory studies.

Neurons are important, but they are not everything. Indeed, it is “cartilage,” in the form of clusters of extracellular matrix molecules called chondroitin sulfates, located in the outside nerve cells, that plays a crucial role in the brain’s ability to acquire and store information.

The “Slicing Problem” is a thought experiment that raises questions for substrate-neutral computational theories of consciousness, particularly, in functionalist approaches.

The thought experiment uses water-based logic gates to construct a computer in a way that permits cleanly slicing each gate and connection in half, creating two identical computers each instantiating the same computation. The slicing can be reversed and repeated via an on/off switch, without changing the amount of matter in the system.
