L'érotisme (2/4) : Philosophie du sexe. Il y a toujours, comme le disait Diderot, "un peu de testicule au fond de nos sentiments les plus purs" ; l'érotisme se déploie dans cette dualité entre humanité et bestialité par laquelle l'érotisme est le propre de l'homme.
Pourquoi se cache-t-on généralement pour faire l'amour ? Même quand on est athée, le sexe a "un petit goût de péché", il y a toujours une part de transgression. Mais cela suffit-il à définir l'érotisme ? Il y a notamment chez Georges Bataille une mystique du sexe qui fait parfois perdre la dimension triviale, profane et concrète de la relation érotique, selon notre invité André Comte-Sponville. Le texte du jour Ne pourrions-nous pas dire qu’il n’y a rien en nous, dans cette prison terrestre, de purement corporel ou de purement spirituel, et que c’est à tort que nous séparons ces éléments chez un homme vivant, et qu’il semble raisonnable que nous nous comportions, dans la pratique du plaisir, aussi favorablement au moins que nous le faisons pour la douleur ?
Medical Xpress: Better memory makes people tire of experiences more quickly. We're fickle creatures.
At least if we can remember to be, according to a new study led by a University of Kansas researcher of marketing and consumer behavior. "People with larger working memory capacities actually encode information more deeply," said Noelle Nelson, lead author of the research published in the Journal of Consumer Research. "They remember more details about the things they've experienced, and that leads them to feel like they've had it more.
That feeling then leads to the large capacity people getting tired of experiences faster. " The study could have implications for marketers seeking to maintain interest in their products and brands. "Our findings suggest that if they can enhance their memory for the other times they've eaten these foods, they may feel satiated and then not seek out those unhealthy things," said Nelson, an assistant professor of marketing and consumer behavior in the KU School of Business.

Yet miraculously, the man was not only fully conscious, but lived a rich and unhindered life, working as a civil servant and living with his wife and two kids, blissfully unaware of the gaping hole in his brain.
His ability to function without so many of the key brain regions previously considered vital for consciousness raises some major questions about existing theories regarding how the brain works and the mechanisms underlying our awareness. For example, neuroscientists have often asserted that a brain region called the thalamus, which relays sensory signals to the cerebral cortex, is indispensable for consciousness. "Origin of the Universe Riddle Solved- and,er, It Wasn't God" Claim Canadian Physicists.
A Group of researchers have made what may turn out to be the most significant discovery in HISTORY – how the cosmos came into being from nothing.
The immense question has concerned religions, philosophers and researchers since the dawn of time but now a Canadian group of scientists consider that they have finally solved this riddle. And the results are so convincing they even challenge the need for religion, or in any case an omnipotent creator – the foundation of all world religions. A group of scientists led by Prof Mir Faizal, at the Dept of Physics and Astronomy, at the University Of Waterloo, Canada, has positively applied the theory to the very creation of existence itself. Medical Xpress: Neurons' faulty wiring leads to serotonin imbalance, depression-like behavior in mice. Columbia scientists have identified a gene that allows neurons that release serotonin—a neurotransmitter that regulates mood and emotions—to evenly spread their branches throughout the brain.
Without this gene, these neuronal branches become entangled, leading to haphazard distribution of serotonin, and signs of depression in mice. These observations shed light on how precise neuronal wiring is critical to overall brain health, while also revealing a promising new area of focus for studying psychiatric disorders associated with serotonin imbalance—such as depression, bipolar disorder, schizophrenia and autism. The findings were published today in Science. "By pinpointing the genes that guide the organization of neurons, we can draw a line between changes to those genes, and the cellular, circuitry and behavioral deficiencies that can occur as a result," said Tom Maniatis, PhD, a principal investigator at Columbia's Mortimer B.

As complex as the human brain is, it more or less has the same fundamental structure as most other backboned animals - which means it can be divided into three general regions: forebrain, midbrain, and hindbrain.

Using just that eye, he silently dictated his memoir, The Diving Bell and the Butterfly, later adapted into a film. The Brain Has Its Own "Autofill" Function for Speech. The world is an unpredictable place.
But the brain has evolved a way to cope with the everyday uncertainties it encounters—it doesn’t present us with many of them, but instead resolves them as a realistic model of the world. The body’s central controller predicts every contingency, using its stored database of past experiences, to minimize the element of surprise. Take vision, for example: We rarely see objects in their entirety but our brains fill in the gaps to make a best guess at what we are seeing—and these predictions are usually an accurate reflection of reality. The same is true of hearing, and neuroscientists have now identified a predictive textlike brain mechanism that helps us to anticipate what is coming next when we hear someone speaking. The findings, published this week in PLoS Biology, advance our understanding of how the brain processes speech.
The study is the first to directly compare humans’ and monkeys’ neural responses with complex sounds. Here's what Cassini heard as it made its daring dive between Saturn and its rings - ImaGeo. A Simon and Garfunkel song comes to mind—and that has scientists scratching their heads as the spacecraft heads today for a second dive.

(Source: NASA/JPL-Caltech) As the Cassini spacecraft swooped between Saturn and its innermost ring on April 26th, one of its instruments listened for the sounds of its passage through the heretofore unexplored region. We Have Weird New Details On The Strangest Symbiotic Relationship Ever Found. How dark matter became a particle. It took decades for dark matter to enter the lexicon of particle physics.
Today, explaining the nature and abundance of dark matter is one of the most pressing problems in the field. Résumé Comment la matière noire est devenue une particule La matière noire, prédite dans les années 1930, est essentielle dans notre connaissance de l’Univers.

En Afrique de l'ouest, et seulement là, des chimpanzés ont une drôle d'habitude : ils jettent de lourdes pierres contre un arbre, toujours le même. La signification de ce comportement est énigmatique. Les découvreurs, qui l'ont décrit en 2016, pensent qu'il est peut-être de la même nature que les rituels humains. WATCH: There's a genetic reason why some people sneeze in the sunshine - ScienceAlert. Like many of us, Derek Muller, host of the YouTube channel Veritasium, has a condition known as a photic sneeze reflex.
The condition affects roughly one in four of us, and makes us sneeze whenever we go from a darker room into the sunshine. Research into the genetics underlying photic sneeze reflex has found that just one letter's difference in our DNA code can determine if someone is a Sun sneezer or not - but we still don't know why humans have evolved such a strange anomaly. The variation is known as a single nucleotide polymorphism, or SNP: a spot where our DNA code varies slightly. And the result can actually trigger the unique photic sneeze reflex, as Derek explains in the video below: New Research Suggests Dark Energy Might be the Reason Time Runs Forward. In Brief A new study may have found a link between dark energy and the Second Law of Thermodynamics—suggesting that the very expansion of the universe may impart a direction to time. About Time. Medical Xpress: Brain 'relay' also key to holding thoughts in mind.
Long assumed to be a mere "relay," an often-overlooked egg-like structure in the middle of the brain also turns out to play a pivotal role in tuning-up thinking circuity. A trio of studies in mice funded by the National Institutes of Health (NIH) are revealing that the thalamus sustains the ability to distinguish categories and hold thoughts in mind. By manipulating activity of thalamus neurons, scientists were able to control an animal's ability to remember how to find a reward.
In the future, the thalamus might even become a target for interventions to reduce cognitive deficits in psychiatric disorders such as schizophrenia, researchers say. The prevailing notion of the thalamus as a relay was based on its connections with parts of the brain that process inputs from the senses. But the thalamus has many connections with other parts of the brain that have yet to be explored, say the researchers. Dr. What kind of information was the thalamus helping to maintain?

Quantum Physics: Are Entangled Particles Connected Via An Undetected Dimension?
This physicist says consciousness could be a new state of matter. Consciousness isn't something scientists like to talk about much. You can't see it, you can't touch it, and despite the best efforts of certain researchers, you can't quantify it. And in science, if you can't measure something, you're going to have a tough time explaining it. But consciousness exists, and it's one of the most fundamental aspects of what makes us human.
And just like dark matter and dark energy have been used to fill some otherwise gaping holes in the standard model of physics, researchers have also proposed that it's possible to consider consciousness as a new state of matter. To be clear, this is just a hypothesis, and one to be taken with a huge grain of salt, because we're squarely in the realm of the hypothetical here, and there's plenty of room for holes to be poked. What is energy? The reason energy is so hard to define is because it’s an abstract notion. In physics, the concept of “energy” is really just a kind of shorthand, a tool to help balance the books. Energy is always conserved (or converted into mass) so is incredibly useful in working out the results of any kind of physical or chemical process. There is no physical “essence” of energy, and no such thing as “pure energy”. Energy is always carried by something, usually in the form of movement. Computer solves a major time travel problem.

Picatrix: An ancient manuscript that teaches how to obtain energy from the cosmos. “Through this ancient manuscript…the reader could attract and channel the energy of the cosmos so that a certain event develops according to the will of the practitioner, zodiacal magic; which is said to help master and dominate with accuracy—through the force of the universe—nature and its surroundings.” The Picatrix is an ancient Arabian book of astrology and occult magic dating back to the 10th or 11th century, which has gained notoriety for the obscene natural of its magical recipes.
The Picatrix, with its cryptic astrological descriptions and spells covering almost every conceivable wish or desire, has been translated and used by many cultures over the centuries, and continues to fascinate occult followers from around the world. The Picatrix was originally written in Arabic, titled Ghāyat al-Ḥakīm, which translates to “The Aim of the Sage" or "The Goal of the Wise.” No long, twisted tail trails the solar system. The solar system doesn’t have a long, twisted tail after all.
