Researchers at Yale University have discovered that the brain is capable of making fructose – a simple sugar, usually found in fruit, vegetables and honey.
Not all sugars are equal. Glucose is a simple sugar that provides energy for the cells in your body. Fructose has a less important physiological role and has been repeatedly linked to the development of obesity and type 2 diabetes. When there is excess glucose the processes that break it down can become saturated, so the body converts glucose into fructose instead, using a process known as the “polyol pathway”, a chemical reaction involved in diabetic complications. The researchers at Yale reported in the journal, JCI Insight, that the brain uses the polyol pathway to produce fructose in the brain.
Now this is what I am talking about when brain stimulation can treat disease and disorders were often better off.
LONDON: A small study in 16 people with severe anorexia has found that implanting stimulation electrodes into the brains of patients could ease their anxiety and help them gain weight.
Researchers found that in extreme cases of the eating disorder, the technique — known as deep brain stimulation (DBS) — swiftly helped many of those studied reduce symptoms of either anxiety or depression, and improved their quality of life.
A few months later, the improved psychological symptoms began to lead to changes in weight, the researchers said, with the average body mass index (BMI) of the group increasing to 17.3 – a rise of 3.5 points – over the course of the study.
I remember a year ago when this 1st came out; nice they are highlighting 1 yr later as a reminder.
British scientists David Thouless, Duncan Haldane and Michael Kosterlitz won this year’s Nobel Prize in Physics “for theoretical discoveries of topological phase transitions and topological phases of matter”. The reference to “theoretical discoveries” makes it tempting to think their work will not have practical applications or affect our lives some day. The opposite may well be true.
To understand the potential, it helps to understand the theory. Most people know that an atom has a nucleus in the middle and electrons orbiting around it. These correspond to different energy levels. When atoms group into substances, all the energy levels of each atom combine into bands of electrons. Each of these so-called energy bands has space for a certain number of electrons. And between each band are gaps in which electrons can’t flow.
If you apply an electrical charge (a flow of extra electrons) to a material, its conductivity is determined by whether the highest energy band has room for more electrons. If it does have room, the material will behave as a conductor. If not, you need extra energy to push the current of electrons into a new empty band and as a result the material behaves as an insulator. Understanding conductivity is vital to electronics, since electronic products ultimately rely on components that are electric conductors, semiconductors and insulators.
While I was at Toy Fair, I swung by the Quantum Mechanix booth to check out their newest Q-Fig offerings, as it’s one of my favorite vinyl statue lines these days. I was not disappointed, as I got to see new addition to the Marvel, DC, and Harry Potter collections, as well as one from ANIMANIACS!
Physicist: As much of a trope as “Other Quantum Worlds” has become in sci-fi, there are reasons to think that they may be a real thing; including “other yous”. Here’s the idea.
Superposition is a real thing (on small scales at least)
One of the most fundamental aspects of quantum mechanics is “superposition “. Something is in a superposition when it’s in multiple states/places simultaneously. You can show, without too much effort, that a wide variety of things can be in a superposition. The cardinal example is a photon going through two slits before impacting a screen: the double slit experiment.
MIT researchers have done even better. MIT has spunout a company called Sistine Solar that has developed a technology to print any kind of image on a skin that can be applied on solar panels, which change the appearance of the photovoltaic cells from all angles, without compromising on their capacity to generate electricity. Founded by the Sloan School of Management at MIT, Sistine Solar hopes to increase the adoption of clean energy with solar panels that mimic the surroundings or environment.
Scientists from the Universidad Carlos III de Madrid (UC3M), CIEMAT (Center for Energy, Environmental and Technological Research), Hospital General Universitario Gregorio Marañón, in collaboration with the firm BioDan Group, have presented a prototype for a 3D bioprinter that can create totally functional human skin. This skin is adequate for transplanting to patients or for use in research or the testing of cosmetic, chemical, and pharmaceutical products.
This research has recently been published in the electronic version of the scientific journal Biofabrication. In this article, the team of researchers has demonstrated, for the first time, that, using the new 3D printing technology, it is possible to produce proper human skin. One of the authors, José Luis Jorcano, professor in UC3M’s department of Bioengineering and Aerospace Engineering and head of the Mixed Unit CIEMAT/UC3M in Biomedical Engineering, points out that this skin “can be transplanted to patients or used in business settings to test chemical products, cosmetics or pharmaceutical products in quantities and with timetables and prices that are compatible with these uses.”
This new human skin is one of the first living human organs created using bioprinting to be introduced to the marketplace. It replicates the natural structure of the skin, with a first external layer, the epidermis with its stratum corneum, which acts as protection against the external environment, together with another thicker, deeper layer, the dermis. This last layer consists of fibroblasts that produce collagen, the protein that gives elasticity and mechanical strength to the skin.
We can even use a vacuum to explain how Quantum is in all things while solving one of the remaining discrepancies in physics.
In the observable universe, number of particles are estimated to be 1080 and if there were some discrepancy in Physics with the explanations of the observable universe or with its each particle then it should confine to factor 1080. I submit that 1080 is a huge figure that forms if one puts eighty zeros after 1. But if the discrepancy is of the factor 10120 then either it is beyond the total number of particles constituting the universe or the physicists might have gravely erred in their calculations. It might be a freak happening that resulted in such a huge quantity. After all, freaks are also the creations of nature or probably the nature itself has erred here. This discrepancy of 10120 is the largest and worst cosmological confusion which can be abbreviated CC and rightly so for cosmological constant as it is the cosmological constant based on Quantum mechanical model. Quantum mechanical model says, energy density of the vacuum is in the range of 10113 Joules per metre cube whereas General Relativity calculates it in the range of 10^−9 Joule per metre cube. An attempt is made to resolve this discrepancy using Spacetime transformation and gravitational gamma Г. Gravitational gamma Г is a term that appears in Schwarzschild solution of general relativity equations.
I submit that vacuum is not nothing but is everything and quantum mechanical model of the vacuum has very large energy density. In the words of John Archibald Wheeler, “Empty space is not empty… The density of field fluctuation energy in the vacuum argues that elementary particles represent percentage‐ wise almost completely negligible change in the locally violent conditions that characterise the vacuum.” That means there are violent conditions or fluctuations although vacuum on large scale appears smooth. Spacetime model has the capability of creating matter, forces, fields and particles. In fact, matter even the entire universe is assumed as spacetime as has been explained in my earlier article, “Matter Is No More Than Fluctuations In Vacuum*.”
I submit that the energy density of the vacuum, due to uncertainty principle, varies from point to point causing fluctuations. In other words, energy density at different points goes on varying even though there is no mass causing gravity. But even then at two points, due to fluctuations of energy density, rate of time may vary, causing difference in time by Planck time. These fluctuations can only be felt at a distance limited to Planck length or at microscopic scale but on macroscopic scale the space time, according to Quantum Mechanical model, appears smooth with no disturbances.
Should the US be concerned when China tells us that our F35s are already obsolete to their own next generation fighter jets now that China has their new radar capability that can detect stealth technology 100 km away?
CHINA claims it has a radical new ‘quantum’ radar capable of detecting stealth fighters at great distances. Does this mean our ultra-expensive new F-35 is obsolete, even before we get it?
The RAAF’s first F-35’s will be making their debut Australian appearance at the Avalon air show this week. It’s not a combat-capable aircraft, yet, though the first partially operational US squadron of the type was deployed to Japan earlier this year.
But Beijing state media has boasted its scientists have successfully tested a new type of radar capable of defeating stealth technology at ranges out to 100km.
