Introduction to algorithm MIT Press. Une comète artificielle, clé des origines. 6 Big HealthTech Ideas That Will Change Medicine In 2012. “In the future we might not prescribe drugs all the time, we might prescribe apps.” Singularity University‘s executive director of FutureMed Daniel Kraft M.D. sat down with me to discuss the biggest emerging trends in HealthTech. Here we’ll look at how A.I, big data, 3D printing, social health networks and other new technologies will help you get better medical care. Kraft believes that by analyzing where the field is going, we have the ability to reinvent medicine and build important new business models.
For background, Daniel Kraft studied medicine at Stanford and did his residency at Harvard. Artificial Intelligence Siri and IBM’s Watson are starting to be applied to medical questions. For example, an X-ray gun in remote africa could send shots to the cloud where an artificial intelligence augmented physician could analyze them. This has the potential to disintermediate some fields of medicine like dermatology which is a pattern based field — I look at the rash and I know what it is. Immoral thoughts: how does the brain react? When a person thinks about naughty things, does one side of the brain get more exercised than the other? Eight scientists studied that question. Their report, Hemispheric Asymmetries During Processing of Immoral Stimuli, appears in the journal Frontiers in Evolutionary Neuroscience. The stated goal is to describe "the neural organisation of moral processing". Debra Lieberman, a professor of evolutionary psychology at the University of Miami, Florida, acts as spokesperson for the team.
They had to work with a few limitations – the same limitations that apply to anyone who tries to describe what's going on in the brain. With the exception of a few crackpots or geniuses, scientists don't claim to understand how the 100,000,000,000 or so parts of the human brain manage to think thoughts. The study does not risk getting bogged down in those larger, complicated conundrums. The scientists sought their answer by recruiting some test subjects.

Loosely speaking, the red, yellow and some blue bits are the skeleton, and the green stuff is squishy. Credit: Frank Krauss, Sherpa. We're measuring all kinds of stuff at the Large Hadron Collider right now. The question we're addressing could be summed up as Does the Standard Model of particle physics work at LHC energies or not? If it works, there is a Higgs boson but not much else new. This begs the question (of me at least) How well do we really understand the predictions of the Standard Model at these energies? This isn't an easy one. The strength of a force can be expressed as a number. This is mostly true at LHC energies, except for when it isn't. The bits when isn't mostly involve the strong nuclear force, Quantum Chromodynamics. For example, aspects of how quarks and gluons are distributed inside the protons we collide can't be calculated from first principles.

While most 13-year-olds spend their free time playing video games or cruising Facebook, one 7th grader was trekking through the woods uncovering a mystery of science.
After studying how trees branch in a very specific way, Aidan Dwyer created a solar cell tree that produces 20-50% more power than a uniform array of photovoltaic panels. His impressive results show that using a specific formula for distributing solar cells can drastically improve energy generation. The study earned Aidan a provisional U.S patent – it’s a rare find in the field of technology and a fantastic example of how biomimicry can drastically improve design.
Photo by Cristian Bortes Aidan Dwyer took a hike through the trees last winter and took notice of patterns in the mangle of branches. His studies into how they branch in very specific ways lead him to a central guiding formula, the Fibonacci sequence. His results did turn out to be incorrect though. . + The Secret of the Fibonacci Sequence in Trees Via Treehugger. OW2.0:Plastic to Oil Fantastic. Scientists select new species for top 10 list; issue SOS. The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists - scientists responsible for species exploration and classification - today announce the top 10 new species described in 2009. On the list are a minnow with fangs, golden orb spider and carnivorous sponge. The top 10 new species also include a deep-sea worm that when threatened releases green luminescent "bombs," a sea slug that eats insects, a flat-faced frogfish with an unusual psychedelic pattern, and a two-inch mushroom that was the subject of a "Bluff the Listener" segment on the National Public Radio quiz show "Wait, Wait Don't Tell Me.
" Rounding out the top 10 list are a banded knifefish, a charismatic plant that produces insect-trapping pitchers the size of an American football, and an edible yam that uncharacteristically sports multiple lobes instead of just one.

By Tony Schwartz | 10:37 AM March 3, 2011 Let’s cut to the chase. Say you decide to go on a fast, and so you effectively starve yourself for a week. At the end of seven days, how would you be feeling? You’d probably be hungry, perhaps a little weak, and almost certainly somewhat thinner. Now let’s say you deprive yourself of sleep for a week.
Here’s what former Israeli Prime Minister Menachem Begin had to say in his memoir White Nights about the experience of being deprived of sleep in a KGB prison: “In the head of the interrogated prisoner a haze begins to form. So why is sleep one of the first things we’re willing to sacrifice as the demands in our lives keep rising? Many of the effects we suffer are invisible.
So how much sleep do you need? When I ask people in my talks how many had fewer than 7 hours of sleep several nights during the past week, the vast majority raise their hands. Great performers are an exception. Go to bed earlier — and at a set time. Si c'est bon pour le moral, c'est bon pour le cœur. Un généticien américain crée la première cellule vivante synthét. L'Homme qui prenait sa femme pour un chapeau. Un article de Wikipédia, l'encyclopédie libre. L'Homme qui prenait sa femme pour un chapeau (titre original : The Man Who Mistook His Wife for a Hat) est un livre publié en 1985 par Oliver Sacks, neurologue d'origine anglaise. Il s'agit plus précisément d'un recueil dans lequel l'auteur décrit les affections « les plus bizarres » qu'il a rencontrées. Le titre provient du cas d'un homme qui savait reconnaître les objets composés de formes géométriques simples, tel un chapeau, mais pas les visages, dont le sien et celui de sa femme.

STEPHEN HAWKING: How to build a time machine. By STEPHEN HAWKING Created: 18:47 GMT, 27 April 2010 All you need is a wormhole, the Large Hadron Collider or a rocket that goes really, really fast 'Through the wormhole, the scientist can see himself as he was one minute ago. But what if our scientist uses the wormhole to shoot his earlier self? He's now dead. So who fired the shot? ' Hello. Time travel was once considered scientific heresy.
To see how this might be possible, we need to look at time as physicists do - at the fourth dimension. But there is another kind of length, a length in time. To see what that means, let's imagine we're doing a bit of normal, everyday car travel. Let's indulge in a little science fiction for a moment. Physicists have been thinking about tunnels in time too, but we come at it from a different angle. Enlarge Nothing is flat or solid. Unfortunately, these real-life time tunnels are just a billion-trillion-trillionths of a centimetre across. The fastest manned vehicle in history was Apollo 10.
