ScienceAlert... Boeing has announced that the ABS3A, the worlds first all-electric propulsion satellite, has commenced its tour of duty. The communications satellite is being operated by ABS, a Bermuda-based satellite network that provides TV, Internet, and cellular services across the world. Unlike conventional satellites, which have mostly used propellant systems that burn chemicals of one kind or another to get about the place, the ABS3A makes use of a xenon-ion propulsion system to achieve thrust. Specifically, the all-electric propulsion system uses electron bombardment to create xenon ions, which are then expelled by the spacecraft, producing thrust in the ...
This new technology converts sea water into drinking water in minutes Post Date: 2015-09-16 07:21:19 by Tatarewicz

ScienceAlert... Purifying dirty water is a notoriously difficult and expensive process - even in California, financial pressures affect what can be done to tackle the severe drought in the area. Those in developing nations have far less money to play around with, which is why a newly invented and ultra-cheap water cleaning process is looking so promising. Developed by a team of researchers at Alexandria University in Egypt, the procedure uses a desalination technique called pervaporation to remove the salt from sea water and make it drinkable. Specially made synthetic membranes are used to filter out large salt particles and impurities so they can be evaporated away, and then the rest is ...
China needs to start looking at 'Robot 2.0' Post Date: 2015-09-16 01:33:08 by Tatarewicz

Want... China needs to begin investing in the next generation of robots rather than simply catching up with existing technology based on its traditional role as the "world's factory," an industry expert said. China's robot industry cannot follow the "world's factory" approach and throw money at partnerships with foreign companies that own leading technologies, said Luo Jun, CEO of the International Robotics and Intelligent Equipment Industry Alliance. The robot industry in China began its rise after the 2008 global financial crisis, which forced companies to look to cost-cutting measures, according to the China Business News. "Around the world, the ...

Like so many other alternative energy panaceas, hydrogen technology remains prohibitively expensive. But researchers at Wisconsin say their breakthrough could make the alternative fuel more affordable. MADISON, Wis., Sept. 14 (UPI) -- Many researchers continue to hold hope for an eco-friendly hydrogen economy -- a comprehensive energy-delivery industry based on hydrogen. Hydrogen can be burned to create heat or used in fuel cells to make electricity. It is also an efficient way to store energy. And unlike fossil fuels, which give off harmful emissions when burned, water is hydrogen's only byproduct. But like so many other alternative energy panaceas, the technology remains ...

ScienceAlert... Researchers in Japan have invented a rechargeable lithium-ion battery that can charge itself using sunlight - no solar cell required. The working prototype was demonstrated at the Innovation Japan 2015 trade show last month in Tokyo, and the team behind it hopes to see the technology integrated into a smart window that can act as both a large rechargeable battery and a photovoltaic cell all at once. The team, led by Mitsunobu Sato, professor at the Department of Applied Physics at Kogakuin University in Japan, announced the development of this device back in 2013. Theyve since been working towards a battery-integrated window that can store energy from ...
Scientists discover path to silence with perfect sound absorption Post Date: 2015-09-13 07:17:01 by Tatarewicz
0 Comments
HONG KONG, Sept. 12 (UPI) -- Physicists from Hong Kong University of Science and Technology have achieved the goal of almost perfect silence via total sound absorption. Instead of building multi-layered gradient-index material meant to absorb all frequencies -- which would be quite thick considering the amount of wavelengths there are -- the researchers used two resonators to come close to completely canceling out sound waves. In a paper published Friday in the journal Applied Physics Letters, researchers explain their use of destructive interference to halt the scattering of sound waves, thus achieving near perfect quiet. Researchers tuned two resonators to the same frequency, which ...

My father, now dead, a mathematician without the slightest leaning toward the esoteric, once told me of driving by night with a friend through the hill country of North Carolina. Suddenly a large truck, lights blazing, came over a crest, passed through their car without a sound, and disappeared in the night. My father said that after a moment he asked, Did you see what I saw? The friend answered Yes. They said no more about it, to each other or anyone else. They would have been thought mad. Over the years I have talked to various people, apparently sane, who have had unexplainable experiences. Some of these had dreamed of the death of someone who shortly ...
Scientists think they know how to test the parallel universes theory - for real Post Date: 2015-09-11 05:25:40 by Tatarewicz
1 Comments
ScienceAlert... The existence of parallel universes may seem like something cooked up by science fiction writers, with little relevance to modern theoretical physics. But the idea that we live in a 'multiverse' made up of an infinite number of parallel universes has long been considered a scientific possibility - although it is still a matter of vigorous debate among physicists. The race is now on to find a way to test the theory, including searching the sky for signs of collisions with other universes. It is important to keep in mind that the multiverse view is not actually a theory, it is rather a consequence of our current understanding of theoretical physics. This distinction ...
Here’s how to get the most life out of your battery Post Date: 2015-09-11 05:06:42 by Tatarewicz

ScienceAlert... If you've ever replaced an otherwise decent smartphone or laptop because its battery life has gone from terrific to can't-use-without-constantly-plugging-in, don't worry, we know your pain. But whenever a device powered by a lithium-ion battery starts to prematurely fail, the guilt trip is almost inevitable: could you have taken better care of it? Were you charging it correctly? Or did that cheap power cord from eBay damage it? In a lithium-ion battery, the ions move between the positive and negative electrodes - a cathode and anode - giving out energy used to power your device. When the battery is connected to a charger, the ions move in the opposite ...

The growing number of scientific studies that have demonstrated consistent electromagnetic anomalies associated with virtually every major earthquake both before and after the event during the last two decades strongly indicate the use of electromagnetic pulse (EMP) weaponry as the actual manmade cause of these so called natural disasters. A quote nearly two full decades ago from then US Secretary of Defense William Cohen at a counterterrorism conference back on April 28, 1997 openly revealed: Others are engaging in even an eco-type of terrorism whereby they can alter the climate, set off earthquakes, volcanoes remotely through the use of electromagnetic waves

UPTON, N.Y., Sept. 4 (UPI) -- The Relativistic Heavy Ion Collider just spit out tiny droplets of a liquid researchers say resembles the seeds of the cosmos, a primordial goo created by the Big Bang, which existed only briefly before cooling into the matter that helped birth stars, galaxies and planets. Scientists have reported seeing the tiny liquid droplets before, but this time, researchers got a better look at the production process. What researchers are calling quark-gluon plasma, or QGP, is the product of a collision between helium-3 nuclei and gold ions. When these particles come into contact at high speeds under the right conditions -- extreme temperatures and densities, ...

Study: Huddling rats behave like 'super-organism' Post Date: 2015-09-04 01:54:57 by Tatarewicz

SHEFFIELD, England, Sept. 3 (UPI) -- Rodents, like penguins, huddle for warmth. And when they do -- new research shows -- the collection of bodies acts like a self-organizing "super-organism." The members of huddling mass rotate, so that outer rats are brought into the warmth of the center before rotating back out. Rotation helps to regulate the group's temperature so none of the rats become too hot or too cold. The rate of rotation varies depending on the external temperature. In modeling this behavior, researchers at the University of Sheffield, in England, showed that the huddled mass resembles the actions of a larger, centrally controlled organism -- able to change shape ...

WOODS HOLE, Mass., Sept. 2 (UPI) -- Synchronized swimming isn't limited to the Summer Games. As a new study reveals, whole colonies of of plankton synchronize their jet-propelled movements. The result is a jellyfish-like unit, moving through the ocean water in unison. Researchers at the Woods Hole Research Center say the species, Nanomia bijuga, could inspire future underwater vehicles. "This is a highly efficient system in which no developmental stage is wasted," John H. Costello, a researcher at the center's Marine Biological Laboratory, said in a press release. "It's a quite sophisticated design, for what would seem like a simple arrangement." Like an ...

ScienceAlert... Ants, why are you being so weird? And can you get that? Just take a message, it's fine. Spoiler: the ants don't pick up, but their bizarre reaction to a ringing iPhone in the video above did give us a new appreciation for how machine-like these insects can be. But why the military-precision reaction to something as innocuous as a vibrating phone? It's all to do with the invisible magnetic forces on Earth that tell dogs where to poop and ants how to find their way home, Australian entomologist Nigel Andrew from the University of New England told the press this week. Perhaps when the phone starts to ring, the radio waves it operates on messes with their sense of ...
