The complexity of memory Now playing "Life comes at us very quickly, and what we need to do is take that amorphous flow of experience and somehow extract meaning from it." In this funny, enlightening talk, educational psychologist Peter Doolittle details the importance — and limitations — of your "working memory," that part of the brain that allows us to make sense of what's happening right now.
Is Your Brain Liberal Or Conservative? The political differences between liberals and conservatives might run as deep as the brain, researchers suggest. Scientists had previously found that some psychological traits were associated with certain political views. For instance, studies have shown that conservatives tend to be more sensitive to threatening faces, while liberals tend to be more open to new experiences. Political ideology has even been found to leave its footprint in how we set up our bedrooms and offices, with liberals' offices judged as significantly more distinctive, comfortable, stylish and colorful than conservatives' offices. Cognitive neuroscientist Ryota Kanai of the University College London and his colleagues reasoned that such fundamental differences in personality might be seen in the brain. They scanned the brains of nearly 120 volunteers to investigate the idea.
How Relying on Algorithms and Bots Can Be Really, Really Dangerous Machines can make decisions. That doesn’t mean they’re right.Illustration: Kronk So you can’t wait for a self-driving car to take away the drudgery of driving? Me neither! But consider this scenario, recently posed by neuroscientist Gary Marcus: Your car is on a narrow bridge when a school bus veers into your lane. Quantum physics enables perfectly secure cloud computing Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. They have performed an experimental demonstration of quantum computation in which the input, the data processing, and the output remain unknown to the quantum computer. The international team of scientists will publish the results of the experiment, carried out at the Vienna Center for Quantum Science and Technology (VCQ) at the University of Vienna and the Institute for Quantum Optics and Quantum Information (IQOQI), in the forthcoming issue of Science. Quantum computers are expected to play an important role in future information processing since they can outperform classical computers at many tasks. The latest research, to appear in Science, reveals that quantum computers can provide an answer to that challenge.
Computational neuroscience Computational neuroscience (also theoretical neuroscience) is the study of brain function in terms of the information processing properties of the structures that make up the nervous system. It is an interdisciplinary science that links the diverse fields of neuroscience, cognitive science, and psychology with electrical engineering, computer science, mathematics, and physics. Computational neuroscience is distinct from psychological connectionism and from learning theories of disciplines such as machine learning, neural networks, and computational learning theory in that it emphasizes descriptions of functional and biologically realistic neurons (and neural systems) and their physiology and dynamics. These models capture the essential features of the biological system at multiple spatial-temporal scales, from membrane currents, proteins, and chemical coupling to network oscillations, columnar and topographic architecture, and learning and memory.

Earth - Why would an animal lose its brain? Sponges don't ponder about the meaning or origin of life. But in some ways they are better at the whole life thing than we are. They have lived for millions more years, surviving on the sea floor by taking in nutrients through their porous bodies. To our eyes, they look almost laughably simple. Breakthrough: The first sound recordings based on reading people's minds SExpand For all of you thinking "it's tinfoil hat time"; you should know aluminum foil doesn't block anything... If you want to get the job done, choose a NATO SDIP-27 Level A (AMSG 720B) certified EMI shielding foil, and make your noggin a Faraday cage! I recommend Mu-copper foil! ಥ‿ಥ You'll thank me later!
Philosophy will be the key that unlocks artificial intelligence To state that the human brain has capabilities that are, in some respects, far superior to those of all other known objects in the cosmos would be uncontroversial. The brain is the only kind of object capable of understanding that the cosmos is even there, or why there are infinitely many prime numbers, or that apples fall because of the curvature of space-time, or that obeying its own inborn instincts can be morally wrong, or that it itself exists. Nor are its unique abilities confined to such cerebral matters. The cold, physical fact is that it is the only kind of object that can propel itself into space and back without harm, or predict and prevent a meteor strike on itself, or cool objects to a billionth of a degree above absolute zero, or detect others of its kind across galactic distances.
Building 'invisible' materials with light A new method of building materials using light, developed by researchers at the University of Cambridge, could one day enable technologies that are often considered the realm of science fiction, such as invisibility cloaks and cloaking devices. Although cloaked starships won't be a reality for quite some time, the technique which researchers have developed for constructing materials with building blocks a few billionths of a metre across can be used to control the way that light flies through them, and works on large chunks all at once. Details are published today (28 July) in the journal Nature Communications.
[ETUDE SCIENCE] Conscious Brain-to-Brain Communication in Humans Using Non-Invasive Technologies Human sensory and motor systems provide the natural means for the exchange of information between individuals, and, hence, the basis for human civilization. The recent development of brain-computer interfaces (BCI) has provided an important element for the creation of brain-to-brain communication systems, and precise brain stimulation techniques are now available for the realization of non-invasive computer-brain interfaces (CBI). These technologies, BCI and CBI, can be combined to realize the vision of non-invasive, computer-mediated brain-to-brain (B2B) communication between subjects (hyperinteraction). Here we demonstrate the conscious transmission of information between human brains through the intact scalp and without intervention of motor or peripheral sensory systems.
