Cosmos Master-Post
“Spread Knowledge, It Is Power, It Is Free”
From the lives of the stars to creation theories, functions of the human brain, and the ongoing search for extraterrestrial intelligence, Cosmos asks big questions. When appropriate, Sagan offers big answers, or asks still bigger–and yes, even spiritual–questions at the boundaries of science and religion.
What’s most remarkable about Cosmos is that it remains almost entirely fresh, with few updates needed to the science that Sagan so passionately celebrates. It is no exaggeration to say that Cosmos–for all the debate it may continue to provoke–is a vital document for humanity at a pivotal crossroads of our history.
The complete landmark TV series – 13 one-hour episodes, including:
I: The Shores Of the Cosmos II: One Voice In the Cosmic Fugue III: The Harmony Of the Worlds IV: Heaven and Hell V: Blues For A Red Planet VI: Travellers’ Tales VII: The Backbone of Night VIII: Travels In Space and Time IX: The Lives Of the Stars X: The Edge Of Forever XI: The Persistence Of Memory XII: Encyclopedia Galactica XIII: Who Speaks For Earth?

Black Holes

Cosmic sink-holes or Black Holes is a region of spacetime from which nothing, not even light, can escape. The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return. It is called “black” because it absorbs all the light that hits the horizon, reflecting nothing, just like a perfect black body in thermodynamics. Quantum mechanics predicts that black holes emit radiation like a black body with a finite temperature. This temperature is inversely proportional to the mass of the black hole, making it difficult to observe this radiation for black holes of stellar mass or greater.

J.R. Eyerman’s peek inside the opening-night screening of Bwana Devil, the first full-length color 3-D feature, certainly is peculiar: Men and women, young and old all angle in the same direction, formally dressed but for those silly specs over their eyes.
Funny as it is, with the audience members coming off like clones of an alien species, there’s also prescience in the photo — not just about the emergence of special effects in cinema but also, on a deeper level, about the hypnotizing nature of our entertainment.

Understanding where technology is heading is more than guesswork. Looking at emerging trends and research, one can predict and draw conclusions about how the technological sphere is developing, and which technologies should become mainstream in the coming years.
Envisioning technology is meant to facilitate these observations by taking a step back and seeing the wider context. By speculating about what lies beyond the horizon we can make better decisions of what to create today.

Autonomo 2030

Charles Rattray’s vision of what the automotive industry will be capable of by the year 2030 is far more feasible that it may seem at first glance. Autonomo, his fully autonomous vehicle concept, certainly looks the part, but should not be dismissed as just another flashy concept car. As car makers worldwide gear up to face the enormous challenges posed by congestion, pollution, and infrastructural deficiencies, Rattray’s final year student project offers a glimpse into the world where these challenges are already a thing of the past. Inspired by biomimicry, sustainability, artificial intelligence and information technology in general, the concept draws on technologies that are already being developed in R&D centers around the world.

Autonomous transport is central to the whole idea. Drawing heavily on the principles of swarm robotics, the self-driving autonomos travel in tight clusters that shift their configurations to maintain an uninterrupted flow of traffic while allowing particular vehicles to reach their respective destinations. This so called “platoon mode” allows to vastly reduce energy consumption through reducing the aerodynamic impact on the vehicles further back down the platoon. Thanks to microwave sensors, the spaces between vehicles are reduced to mere 20cm (7.8 inches), as keeping a safe distance from cars ahead is no longer required. Another type of microwave detectors scan the road surface ahead to prime the suspension accordingly and provide a smoother ride.

Later Terminator: We’re Nowhere Near Artificial Brains
How can we be near a digital brain when we can’t even fully decipher the workings of the 300 neurons of C. elegans? And if we can’t answer the question of why brain size isn’t related to intelligence in different animals? Furthermore, our neural systems aren’t written in “sharp joints” (hard-wired connections) like physical circuits.
This is a great read on why the dream of digital brains is still just that … a dream. We aren’t close to building one, despite what IBM wants you to think. But we are learning a lot of fun stuff along the way.

Display interface in thin air

Displair, a Russian company from Astrakhan, has come up with a technology to project images into the thin air, and use gestures to move them.

The company uses a stream of cold fog to project images onto it and an infrared camera to capture gestures. Unlike oversized body movements that Microsoft Kinect analyze and process using motion camera and infrared depth sensors, Displair solves a bigger challenge of detecting and interpreting finer movements of hands.

When manufactured in large quantities, the device may cost between $4000 and $30 000.

Why do many psychiatric disorders emerge during adolescence? 
Adolescence is a critical developmental time period marked by the increased incidence of a myriad of psychiatric illnesses, including but not limited to: anxiety and mood disorders, eating disorders, substance abuse disorders and psychosis. It is believed that abnormalities in maturational events that typically accompany adolescence may contribute to psychopathologies. 
Areas of research that study the effect of aberrant brain and neural development typically focus on studying and understanding: 
Trajectories of grey/white matter volume and cortical thickness: MRI evidence suggests that cortical grey matter and cortical thickness decrease during adolescence, which has commonly been interpreted as being the result of synaptic pruning, a process by which redundant (and therefore unnecessary) synapses are eliminated through an experience-dependent process throughout early development. However, these decreases in volume/thickness do not apply to all brain areas, as some display a nonlinear relationship with age. Volumes of white matter usually show a linear increase throughout childhood and adolescence.
Changes in myelination and synaptic pruning and their effect in the formation of functionally interconnected circuits: This is one of the most popular areas of study, as changes in synaptic pruning and myelination have been the most popular explanations for the structural differences in the adolescent brain. Early post-mortem studies have indicated a decrease in the number of synapses during childhood and adolescence. Newer evidence, however, has indicated that the gradual decrease of synapse number begins in childhood (in several cortical regions) and continues through adolescence. 
Changes in brain activity of neural networks: Age-related changes in neural connectivity and neurotransmission are thought to underlie the functional changes associated with adolescence.Using fMRI techniques, researches have found that adolescents show differential functional connectivity across multiple circuits. Some of these include: the action-observation network, considered by many to be the neural substrate of imitation; the biological-motion processing network, also known as the superior temporal sulcus (STS) network, implicated in the extraction and encoding of socially relevant cues imparted by movement (i.e. eyes, hands, etc); and, the executive network, which underlies multiple cognitive processes involved in decision-making and working memory.Adolescents have also long been regarded as being high risk takers and displaying increased novelty-seeking behaviors.
Neurochemistry: Finally, the efficacy of communication and integration of neural networks depends on neurotransmission and the state of these transmitter systems. Due to the experimental constraints of studying human children and adolescents, the scientific knowledge of developmental changes in neurotransmitter systems is limited. Most of the known data comes from post-mortem or nonhuman primate studies. However, one of the better studied systems is the developmental changes in dopamine neurotransmission and its relation to adolescent-specific changes in motivational behavior. The mesolimbic dopamine pathway, a key circuit implicated in reward and addiction, has been found to be anatomically and functionally distinct in adolescents. 
After reading all of this, one thing is clear: there is no single answer. Adolescence is the product of many integrated developmental and functional changes. Both our body and our brains are constantly changing to reflect what we’ve learned and what is necessary for survival. Additionally, many other factors come into play in influencing healthy and normal development like sleep patterns, history of disease, hormonal changes underlying puberty, dietary habits and teenage smoking/drinking.
