Invisible Worlds Richard Hammond's Invisible Worlds is a BBC television documentary programme presented by Richard Hammond that features state-of-the-art camera technology used to focus on what humans cannot see with the naked eye. It is one series long consisting of three episodes. 1. Speed Limits - Richard Hammond explores the extraordinary wonders of the world of detail hidden in the blink of an eye. The human eye takes about fifty milliseconds to blink. What new marvels would we see? 2. From death-defying aerial repairmen in the United States using ultraviolet cameras to seek out an invisible force that lurks unseen on power lines, to German scientists unlocking the secrets of animal locomotion with the world's most powerful moving x-ray camera, to infrared cameras that can finally reveal the secrets within a humble beehive, he shows how new technologies are letting us see our world anew. 3.

Consciousness of subjective time in the brain — PNAS Author Affiliations Contributed by Endel Tulving, November 9, 2010 (sent for review June 13, 2010) Abstract “Mental time travel” refers to conscious experience of remembering the personal past and imagining the personal future. Little is known about its neural correlates. Here, using functional magnetic resonance imaging, we explored the hypothesis that mental time travel into “nonpresent” times (past and future) is enabled by a special conscious state (chronesthesia).

Consciousness Representation of consciousness from the seventeenth century At one time consciousness was viewed with skepticism by many scientists, but in recent years it has become a significant topic of research in psychology, neuropsychology and neuroscience. The primary focus is on understanding what it means biologically and psychologically for information to be present in consciousness—that is, on determining the neural and psychological correlates of consciousness. The majority of experimental studies assess consciousness by asking human subjects for a verbal report of their experiences (e.g., "tell me if you notice anything when I do this"). Issues of interest include phenomena such as subliminal perception, blindsight, denial of impairment, and altered states of consciousness produced by drugs and alcohol, or spiritual or meditative techniques.

The period of the brain pretending to be the mind The mind is different from the brain , just as psychology is different from biology. Although mental processes are associated with some biochemical/neurological operations, some researchers and the popular media have misrepresented the association between the two systems as the causal relation (biochemical changes cause psychological experiences) or simply seen the two as the same. With the growing use of psychophysiological measures such as fMRI, PET, EEG, MEG, and optical neuroimaging, it has become pervasive to hear that biological events underlie (are more fundamental than) psychological events. Fortunately, some psychologists (e.g., Beck, 2010; Gernsbacher, 2010; Miller, 2010) have identified major problems with the claim that "biological events underlie the psychological events." First, Correlation is not causation. For example, research has show that after aerobic exercise, there were structural and functional brain changes. References
Google: Behind the Screen What if all the information in the world was categorized and easily searchable? What if all the news from around the world, all books, written texts, photos and videos that exist on a place in the world would be collected, and would be available everywhere? That is precisely the goal of Google and it will not be long for it to be realized. Through the well-known search engine, Google Earth, where all information is classified by geographical location, along with Google Books, a project where Google digitizes complete libraries. Tegenlicht visits the head office of Google in Mountain View, California and spoke with Vint Cerf, who commissioned by the American army is the forerunner of the developed Internet. Cert now works at Google, where he helps to create and develop new possibilities for the Internet. Google grows like a cabbage and they continue to hire more and more smart people in order to achieve their company goal faster. Watch the full documentary now
More Than Meets the Mirror: Illusion Test Links Difficulty Sensing Internal Cues with Distorted Body-Image With all of the New Year's diet ads claiming you can lose dozens of pounds in seemingly as many days, you probably are not alone if you looked in the mirror this morning and saw a less than ideal body. Or maybe you just picked up a new magazine in which already thin models have their remaining flesh scavenged by Photoshop to make them appear even slimmer. With all of these unrealistic promises and images, it can be hard to gain an accurate sense of one's own body. But the disjunction for some people might go deeper than manipulated photos. A new study shows that the way people perceive their external appearance is likely linked to how they experience their bodies internally. "The sense of self is built up from a representation of internal states," says Hugo Critchley, a professor of psychiatry at the University of Sussex in England who was not involved with the study. Most of the time, the image someone has of their body is pretty close to its external appearance.
The Blog : The Mystery of Consciousness II (Photo by h.koppdelaney) The universe is filled with physical phenomena that appear devoid of consciousness. From the birth of stars and planets, to the early stages of cell division in a human embryo, the structures and processes we find in Nature seem to lack an inner life. At some point in the development of certain complex organisms, however, consciousness emerges. This miracle does not depend on a change of materials—for you and I are built of the same atoms as a fern or a ham sandwich. Many readers of my previous essay did not understand why the emergence of consciousness should pose a special problem to science. This situation has been characterized as an “explanatory gap” and the “hard problem of consciousness,” and it is surely both. However, many people imagine that consciousness will yield to scientific inquiry in precisely the way that other difficult problems have in the past. Scarcely twenty years passed before our imaginations were duly stretched. Unfortunately, no.
The Search for Life: The Drake Equation For many years our place in the universe was the subject of theologians and philosophers, not scientists, but in 1960 one man changed all that. Dr Frank Drake was one of the leading lights in the new science of radio astronomy when he did something that was not only revolutionary, but could have cost him his career. Working at the National Radio Astronomy Observatory in Greenback in Virginia, he pointed one of their new 25-meter radio telescopes at a star called Tau Ceti twelve light years from earth, hoping for signs of extra-terrestrial intelligence. Although project Ozma resulted in silence, it did result in one of the most seminal equations in the history of science - the Drake Equation - which examined seven key elements necessary for ET intelligence to exist, from the formation of stars to the likely length a given intelligent civilization may survive. However, in the 50 years of listening that has followed, not one single bleep has been heard from ET.
The Roots of Consciousness: Theory, The Biological Perspective The Biological Perspective In the Introduction, I discussed the evolution of organized matter from the photon through particles, atoms and molecules to living cells which begin to differentiate in structure and function forming a wide variety of tissues and organs that play a specialized function in the human body. It is reasonable to assume all these levels of organization including the whole human being play a role in shaping consciousness. Particularly important are the nervous system, comprising brain and spinal cord, and the endocrine system, comprising a number of ductless glands that secrete hormones into the bloodstream. Many biological scientists today implicitly believe that these structures not only shape consciousness, but are actually the source of conscious awareness. This view is known as the biological identity theory. The Nervous System Neuron cells are the principle units of the nervous system.

Think time flies? Well actually, you may be right - Technology & science - Tech and gadgets - Gizmodo Time flies when you're having fun. But you're at work, and work sucks. So how is it 5 p.m. already? When we talk about "losing time," we aren't referring to that great night out, or that week of wonderful vacation, or the three-hour film that honestly didn't feel like more than an hour. No, when we fret about not having enough time, or wonder where exactly all those hours went, we're talking about mundane things. Why does that happen? First of all, yes In understanding any complex issue, especially a psychological one, intuition doesn't usually get us too far. But not today. "Philosophers have written on (the perception of time) for a long period, and psychology has been interested in it since its inception as a separate discipline — since the late 1800s," explains Dr. Brown says that common wisdom about how time "flies" is basically correct. This jibes with common experience as well as decades of experimentation. The secret, Brown says, is something called habituation. But why?
