A little 'musical' but point made. I watched a special on the work done by the russians in that area. Amazing stuff!
Indeed, but it's always dangerous messing with viruses, as just seen above... We'll see what happens... Btw, it's largely Georgians...

Photograph: Bob Mumgaard/Plasma Science and Fusion Center/MITDamian Carrington A nuclear fusion world record has been set in the US, marking another step on the long road towards the unlocking of limitless clean energy. A team at the Massachusetts Institute of Technology (MIT) created the highest plasma pressure ever recorded, using its Alcator C-Mod tokamak reactor. High pressures and extreme temperatures are vital in forcing atoms together to release huge amounts of energy. Nuclear fusion powers the sun and has long been touted as the ultimate solution to powering the world while halting climate change. But, as fusion sceptics often say, the reality has stubbornly remained a decade or two away for many years. Now MIT scientists have increased the record plasma pressure to more than two atmospheres, a 16% increase on the previous record set in 2005, at a temperature of 35 million C and lasting for two seconds. The breakthrough was presented at the International Atomic Energy Agency’s fusion summit in Japan on Monday. Successful fusion means getting more energy out than is put in and this requires the combination of pressure, temperature and time to pass a critical value at which point the reaction becomes self-sustaining. This remains elusive but the MIT record shows that using very high magnetic fields to contain the plasma may be the most promising route to practical nuclear fusion reactors. “This is a remarkable achievement,” said Dale Meade, former deputy director at the Princeton Plasma Physics Laboratory. “The record plasma pressure validates the high-magnetic-field approach as an attractive path to practical fusion energy.” Prof Riccardo Betti, at the University of Rochester, New York, said: “This result confirms that the high pressures required for a burning plasma can be best achieved with high-magnetic-field tokamaks such as Alcator C-Mod.” However, the world record was achieved on the last day of the MIT tokamak’s operation, because funding from the US Department of Energy has now ended. The US, along with the EU, China, India, South Korea, Russia and Japan, are now ploughing their fusion funding into a huge fusion reactor called ITER. The giant, seven-storey-high tokamak is being built in southern France, with magnets weighing about the same as a Boeing 747. The volume of ITER’s tokamak will be 800 times bigger than the MIT vessel. ITER should be completed in 15-20 years and aims to deliver 500MW of power, about the same as today’s large fission reactors. But the project has been hampered by delays. [/FONT]
Beautiful!!! This is why I do love science... Our only way out to vast majority of our problems, of course besides of human emotions.
Could a Mysterious, Brand New Planet Be to Blame for Our Tilted Sun? A new study released this week said that a distant, undiscovered planet may be responsible for the wobble in our solar system, tilting the planets by as much as six degrees. The culprit? The mysterious Planet Nine, said to be lurking deep in the Milky Way. "Because Planet Nine is so massive and has an orbit tilted compared to the other planets, the solar system has no choice but to slowly twist out of alignment," said Elizabeth Bailey, lead author of the study announcing the discovery... more
SkunkLock offers best protection for bikes Even with expensive bike locks in place, many people have found their prized possessions have been swiped, with thieves able to cut through U-locks in minutes using handheld electric saws. But a new locking device promises to stop criminals by making them vomit uncontrollably. The hardened medium-carbon steel U-Lock is pressurized inside with noxious chemicals so harsh, they almost always induce vomiting. If that isn’t enough of a deterrent, they can also cause temporary blindness and make breathing difficult for the criminal, who by now is probably regretting his chosen occupation. Once in this debilitated state, it’s highly unlikely any thief would try to make a getaway on a stolen bike. The SkunkLock doesn’t contain any electronics and it’s legal in the US, mainly because it falls under similar regulations as pepper sprays. It’s also safe for owners – the gas will only erupt when someone cuts about 30 percent into the lock. The inventors say the gas is effective through the most “robust” gas masks. Early bird specials offer the lock from $99, with an estimated shipping date of June 2017. https://www.indiegogo.com/projects/skunklock-the-only-bike-lock-that-fights-back-bicycle#/
^^ @Katz, ok very interesting dude, if this are here in Brazil this Company stay giant trust me LOL, one little correction: protection for bicycle and or bike (motorcycle)
Are These Strange Signals Evidence of Alien Life? Whenever anyone says that it's aliens, you can be pretty sure that it's not aliens. However, a team of scientists are making the case that maybe, just maybe, it is this time. Two astronomers from the Université Laval in Quebec have published a study examining a large number of stars from the Sloan Digital Sky Survey. They found that of the millions of stars catalogued by the Survey, a handful were exhibiting "spectral modulation." Essentially, the stars were changing color slightly, and these color fluctuations appear to have a repeatable pattern. What's more, this spectral modulation appears to be identical across many different stars. The study authors believe that this is evidence of an alien civilization manipulating stars to send us a message. Of course, there are other explanations for this seemingly coordinated behavior. The authors believe that this spectral modulation could also be the result of some kind of rare chemical makeup only present in a handful of stars. And currently, this results would have to be independently verified by another observatory before we can take them seriously. There is still substantial doubt in the astronomical community that these results are evidence of extraterrestrial life. However, if these results are verified by additional studies, then it could be strong evidence that another intelligent species in the Cosmos is trying to reach us. Source link
New stricter wine drinking recommendations Until recedntly, health authorities advised that men should drink up to 3 glasses of wine per day and women up to 2. But new guidelines reduce both amounts by one glass: “According to the Dietary Guidelines for Americans, moderate alcohol consumption is defined as having up to 1 drink per day for women and up to 2 drinks per day for men. This definition is referring to the amount consumed on any single day and is not intended as an average over several days. However, the Dietary Guidelines do not recommend that individuals who do not drink alcohol start drinking for any reason.” http://www.cdc.gov/alcohol/faqs.htm Not the first time that health guidelines change, and I wonder what meaning the present ones have if they’re expected to change again…and again…
NASA's $8.7 Billion Telescope Is Ready for Final Tests November 3 A full-scale model of the James Webb Space Telescope assembled on the lawn at Goddard Space Flight Center that shows the scale of its size, March 1, 2013. Photo: NASA The launch isn't until October 2018, but there's one big difference between Hubble and Webb. For Webb, there will be no dramatic rescue mission. The space telescope will be parked at the L2 point, which is a million miles away from Earth. So the pressure is on at Goddard and its contractors to make sure the Webb doesn't end up like Hubble. NASA engineers will fold up the entire instrument into the cargo bay of a French Ariane rocket, send it aloft, then after reaching its parking spot, unfurl its tennis court-sized solar umbrella to protect the delicate instruments. ... The Webb telescope will be bigger and better than Hubble by more than tenfold, according to NASA, with seven times more light collecting surface. By capturing images of infrared light that is farther away (and therefore longer ago in time) than visible light, it will be able to see objects that formed just after the Big Bang. It will also be able to zoom in on the planets orbiting stars, such as the possible "Earth-like" exoplanet discovered recently around neighboring Proxima Centauri. The Webb is an engineering marvel composed of 18 hexagonal mirrors that can adjust themselves to form a smooth collecting surface. The mirrors are covered in thin layers of gold and beryllium to reflect and collect certain wavelengths of infrared light. Inside the huge clean room at Goddard, the Webb telescope looks like a gold-plated Pilgrim's hat tipped on its side. Now that the telescope is assembled, it will begin several months of shake, vibration and acoustic testing at Goddard to make sure it can handle the rigors of its launch from French Guiana. http://www.space.com/34610-james-webb-space-telescope-hubble-repair-mission-astronomy.html
Argonne researchers posit way to locally circumvent Second Law of Thermodynamics For more than a century and a half of physics, the Second Law of Thermodynamics, which states that entropy always increases, has been as close to inviolable as any law we know. In this universe, chaos reigns supreme. But researchers with the U.S. Department of Energy's (DOE's) Argonne National Laboratory announced recently that they may have discovered a little loophole in this famous maxim. Their research, published in Nature Scientific Reports, lays out a possible avenue to a situation where the Second Law is violated on the microscopic level... more
