Sleep Homeostasis and Models of Sleep Regulation Peter Achermann According to the two-process model of sleep regulation, the timing and structure of sleep are determined by the interaction of a homeostatic and a circadian process. The original qualitative model was elaborated to quantitative versions that included the ultradian dynamics of sleep in relation to the non-REM-REM sleep cycle. The time course of EEG slow-wave activity, the major marker of non-REM sleep homeostasis, as well as daytime alertness were simulated successfully for a considerable number of experimental protocols. Perfect Faults: A Self-Correcting Crystal May Unleash the Next Generation of Advanced Communications Researchers from the National Institute of Standards and Technology (NIST) have joined with an international team to engineer and measure a potentially important new class of nanostructured materials for microwave and advanced communication devices. Based on NIST's measurements, the new materials—a family of multilayered crystalline sandwiches—might enable a whole new class of compact, high-performance, high-efficiency components for devices such as cellular phones.* "These materials are an excellent example of what the Materials Genome Initiative refers to as 'materials-by-design'," says NIST physicist James Booth, one of the lead researchers. "Materials science is getting better and better at engineering complex structures at an atomic scale to create materials with previously unheard-of properties." The new material has layers of strontium oxide, believed to be responsible for the self-correcting feature, separating a variable number of layers of strontium titanate. *C-H Lee, N.D.
New Zealand Man is 3D-Printing a Fully-Functional 1961 Aston Martin Replica New Zealander Ivan Sentch is 3D printing an entire 1961 Aston Martin DB4 replica! Using a CAD rendering from TurboSquid, which he modified to suit his design goals, Sentch has so far produced 2,500 fiberglass molds and four four-inch sections that he has mounted on a wooden frame and glued into place. He spent about $2,000 on plastics for the 3D printing, and now plans to build a mold for a fiberglass exterior shell. There are only 1,200 existing models of the 1961 Aston Martin DB4 in the world, each costing between several hundred thousand to $1 million on the auction circuit. Because of its limited availability, software engineers can’t get a hold of detailed designs, which eventually forced Sentch to crib a CAD rendering from TurboSquid to get his car built. It may not look like it, but Sentch has been using the 3D printing technology only since last December. So far he’s spent about $2,000 on the 3D printing material and still plans to create the exterior shell out of fiberglass.
4 Ways to Heal your Body using Crystals Now that we’ve made a post about all of the different types of crystals there are available, I thought it might be a good opportunity to talk about what we can use them for. Obviously, Crystals have many practical applications in the mainstream world. Did you know that all of our Computer Technology is based off of the core Element that Crystals are? Fyi – It’s Silicon, and that’s just the tip of the iceburg. So besides massive amount of Data Storage and Computing Technology, Crystals also can have an effect on your body too. Consider Crystals like Materia from FF7…. Here are 4 ways that you can use Crystals to facilitate healing in your body. Before we begin, let me share with you this prerequisite to using any and all of your crystals: Let them sit in the sun for several hours before you use them, this will charge them with the life-bearing energy of the sun, and it can be fuelled through the crystals into you. Now that your crystals are all charged, we can do the following 1. 2. 3. 4.
Stop Hyping Big Data and Start Paying Attention to 'Long Data' | Wired Opinion Our species can’t seem to escape big data. We have more data inputs, storage, and computing resources than ever, so Homo sapiens naturally does what it has always done when given new tools: It goes even bigger, higher, and bolder. We did it in buildings and now we’re doing it in data. Sure, big data is a powerful lens — some would even argue a liberating one — for looking at our world. Despite its limitations and requirements, crunching big numbers can help us learn a lot about ourselves. But no matter how big that data is or what insights we glean from it, it is still just a snapshot: a moment in time. Samuel Arbesman is an applied mathematician and network scientist. By “long” data, I mean datasets that have massive historical sweep — taking you from the dawn of civilization to the present day. Because as beautiful as a snapshot is, how much richer is a moving picture, one that allows us to see how processes and interactions unfold over time? We also need to build better tools.
Praise as Manipulation: 6 Reasons to Question Compliments Source: Fake Smile / Flickr As long as another’s praise doesn’t sound patently insincere, you’re likely to welcome it. Being richly recognized for what you do—or who you are—just feels good. It’s wonderfully confirming, as reassuring as it is validating. Most of us thrive on compliments and flattery precisely because they can buoy us up, warm our hearts, and allay old fears and self-doubts. article continues after advertisement But praise has its dark side, too. If you’re insecure, and so require external confirmation to feel worthwhile or good about yourself, you’ll be especially susceptible to (or a “target” for) disingenuous praise with invisible strings (or a price tag) attached to it. This is hardly to suggest that you should be suspicious (or paranoid) upon any instance of another’s positive acknowledgment. Here are six ways flatterers might, covertly, be scheming to “take you in”: I've also written a series of posts on getting conned. © 2014 Leon F.
Hempcrete Could Change The Way We Build Everything When it comes to new and sustainable housing ideas, it seems to always be about creating a more efficient home in terms of insulation, lighting, electricity, etc. Mainstream belief on the subject would have you believe that top corporations and government projects are working with the best possible technology to bring forth solutions that work and are going to be great for the environment. If that was truly the case, I can guarantee you that the whole world would be using Hempcrete right now. Haven’t heard of it? I’m not too surprised. First off, what is Hempcrete? Since lime is the binding material, builders do not have to heat up the lime as much as a supplier would need to in the industrial creation of concrete. conservation when producing Hempcrete vs. concrete. Hempcrete is a much more superior building material due to the fact that it is a very strong, lightweight and breathable material. petrify but is still incredibly strong.
Chinese Scientists Grow False Teeth From Human Urine Over the years scientists have made false teeth from a variety of materials – from cuspids crafted out of animal bone to chompers made from wood and gold. However a group of Chinese scientists just announced that they have successfully grown “rudimentary teeth” from an extremely unlikely and slightly unsettling source: human pee. According to the research, published in Cell Regeneration Journal, the tiny tooth-like structures were grown from stem cells harvested from urine. While the scientists believe it could herald a new, albeit disturbing, age for false teeth, stem cell researchers believe they could have several hurdles to overcome. These cells were then mixed with organic material to form teeth. Prof Chris Mason, a stem cell scientist at University College London, said to BBC News that urine was a poor starting point and “was probably one of the worst sources [for stem cells]. Yes, there’s that and the fact that many people probably wouldn’t be too keen on urine-based teeth.
(1) Water Not For Sale March on Jasper Avenue in Edmonton. Oh, those crazy Frenchies: Facebook faces family photo tax in France High performance access to file storage Facebook should pay the French government for hosting the holiday photos and status updates of the French people, a new report commissioned by the French government has suggested. The new 200-page report* on taxing the digital economy - commissioned by four French Cabinet Ministers - proposes that France should tax data collection. The touted idea would see new tax bills from the French government landing on Google, Facebook, Amazon and any other web companies that store data about their French users. The report was commissioned in July by Fleur Pellerin, France's Minister for Small and Medium Enterprise, Innovation and the Digital Economy, backed by three colleagues amid government frustration about the low tax American web giants were paying in France. Web companies pay under 1 per cent of what a standard French company would pay in tax, according to figures from Le Monde. French wonks: Let's tax data like we tax pollution
Scientists Finally Show How Your Thoughts Can Cause Specific Molecular Changes To Your GenesTunedBody With evidence growing that training the mind or inducing certain modes of consciousness can have positive health effects, researchers have sought to understand how these practices physically affect the body. A new study by researchers in Wisconsin, Spain, and France reports the first evidence of specific molecular changes in the body following a period of intensive mindfulness practice. The study investigated the effects of a day of intensive mindfulness practice in a group of experienced meditators, compared to a group of untrained control subjects who engaged in quiet non-meditative activities. After eight hours of mindfulness practice, the meditators showed a range of genetic and molecular differences, including altered levels of gene-regulating machinery and reduced levels of pro-inflammatory genes, which in turn correlated with faster physical recovery from a stressful situation. The study was published in the Journal Psychoneuroendocrinology. According to Dr. In fact, Dr. Dr.
