Some paradoxes - an anthology How to increase serotonin in the human brain without drugs Understanding Evolution The bacteria that changed the world - May, 2017 The make-up of Earth's atmosphere, once the domain of Earth science textbooks, has become an increasingly "hot" news topic in recent decades, as we struggle to curb global warming by limiting the carbon dioxide that human activity produces. While the changes that humanity has wrought on the planet are dramatic, this isn’t the first time that one species has changed Earth’s atmosphere. Three billion years ago, there was no free oxygen in the atmosphere at all. Life was anaerobic, meaning that it did not need oxygen to live and grow. That all changed due to the evolution of Cyanobacteria, a group of single-celled, blue-green bacteria. Read the rest of the story here | See the Evo in the News archive

Relativistic Baseball What would happen if you tried to hit a baseball pitched at 90% the speed of light? - Ellen McManis Let’s set aside the question of how we got the baseball moving that fast. We'll suppose it's a normal pitch, except in the instant the pitcher releases the ball, it magically accelerates to 0.9c. From that point onward, everything proceeds according to normal physics. The answer turns out to be “a lot of things”, and they all happen very quickly, and it doesn’t end well for the batter (or the pitcher). The ball is going so fast that everything else is practically stationary. The ideas of aerodynamics don’t apply here. These gamma rays and debris expand outward in a bubble centered on the pitcher’s mound. The constant fusion at the front of the ball pushes back on it, slowing it down, as if the ball were a rocket flying tail-first while firing its engines. After about 70 nanoseconds the ball arrives at home plate. Suppose you’re watching from a hilltop outside the city.

NLP: Neuro Linguistic Programming – Part 1 According to Neuro Linguistic Programming (NLP), 10% of the mind is conscious, leaving 90% of the mind to the unconscious. Now what does this mean? The conscious mind is simply what we are focused on at any given moment. On the other hand, the unconscious is the massive store of every experience, belief, habit, method and thought we have ever had. Think of the conscious being the area of a dark hole that is illuminated by a torch (our mind). NLP states that there are programs in our unconscious that dictate how we think and act. During the 1970′s, Richard Bandler and John Grinder studied therapy sessions transcripts from Fritz Perls, Milton Erickson and Virginia Satir — three of the most renowned psychologists of the time. After years of studying these transcripts and modeling them in sessions with their own patients, Bandler and Grinder came up with 3 rules for successful communication in therapy, business and sales: 1. More articles on the complex subject of NLP to come.

An Essay by Einstein -- The World As I See It "How strange is the lot of us mortals! Each of us is here for a brief sojourn; for what purpose he knows not, though he sometimes thinks he senses it. But without deeper reflection one knows from daily life that one exists for other people -- first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy. A hundred times every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I must exert myself in order to give in the same measure as I have received and am still receiving... "I have never looked upon ease and happiness as ends in themselves -- this critical basis I call the ideal of a pigsty. "My passionate sense of social justice and social responsibility has always contrasted oddly with my pronounced lack of need for direct contact with other human beings and human communities.

Changes in brain activity related to eating chocolate Introduction Early cortical representations of visual, auditory and somatosensory information (e.g. `primary' and `secondary' areas) are in the unimodal neocortex. In contrast, the cortical representations of the chemical senses (taste and smell) are in the limbic and paralimbic cortex. This is true in primates (e.g. Tanabe et al., 1975a, b; Pritchard et al., 1986; Takagi, 1986; Price, 1990; Baylis et al., 1995; Rolls et al., 1996; Scott and Plata-Salaman, 1999) and in humans (Zatorre et al., 1992; Jones-Gotman and Zatorre, 1993; Petrides and Pandya, 1994; Faurion et al., 1999; Pritchard et al., 1999; Small et al., 1999). Many neuroimaging studies have investigated brain activity evoked by affective stimuli, including chemosensory stimuli. To investigate brain activity related to affective changes associated with feeding, we performed successive H215O-PET scans on volunteers as they ate chocolate to beyond satiety. Fig. 1 Rating scale.

The Origin and Evolution of Cells - The Cell - NCBI Bookshelf RuSpace | Soyuz console Fighter jet and spaceship cockpits seem to fascinate me and that of the Soyuz is no exception; unfortunately there are no detailed diagrams or manuals publically-available on the Internet that I know of! The following diagrams are ones I have collected from various places, and are the best I can do at the moment. The Soyuz TM Information Display System is called the “Neptune”, «Нептун»; for the TMA it is the Neptune ME. Some of the buttons and controls on the console can’t be reached without a stick to poke at them! The stick is called Указател, Ukazatel, “Pointer”. The computer used on the Soyuz is called Argon, «Аргон». Some of the Russian translations below are uncertain or unclear (I couldn’t find exact definitions for them).

To Map Or Not To Map The Brain? That's Tonight's Question : Krulwich Wonders... "Mind is such an odd predicament for matter to get into," says the poet Diane Ackerman. "If a mind is just a few pounds of blood, dream and electric, how does it manage to contemplate itself? Worry about its soul? Do time and motion studies? Admire the shy hooves of a goat? ...How can a neuron feel compassion?" Yes, how? All over the world, neuroscientists are beginning to address these questions, which are really the same question: How do gooey, stringy brain cells produce a mind? How would you do it? Thomas Deerinck and Mark Ellisman/Portraits of the Mind Do Experiences Re-Wire Our Brains? Well, we begin with a hypothesis: that when I have a significant experience, that experience literally changes me. So suppose I'm at a high school dance and I see a beautiful girl across the room, and I ask a friend, "Who is that?" Remember what happens to Tony in West Side Story? Mariaaaaaaaaa! Or, if you're not into Broadway musicals, let's say Tony's brain has created a neuronal pattern.
