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. They’ve since been working towards a battery-integrated window that can store energy from ...
Scientists discover path to silence with perfect sound absorption

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 ...

CHENGDU, Sept. 11 (Xinhua) -- China will invest more than one billion yuan (about 157 million U.S. dollars) to build a high altitude observatory in the southwest to monitor cosmic rays, local authorities said on Friday. The observatory, the second of its kind in China, will be built in the Tibetan Autonomous Prefecture of Garze in southwest China's Sichuan Province, said Cao Zhen, a research fellow with the Institute of High Energy Physics (IHEP) under Chinese Academy of Sciences. The Garze government and IHEP inked an agreement on Wednesday that will see the observatory built on Haizi Mountain in Daocheng County, where the average altitude is 4,410 meters. "With an acute ...

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

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

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 ...

SeattleTimes... HONG KONG — As President Xi Jinping of China prepares for his first state visit to the United States this month, Washington has warned it could hit Chinese companies with sanctions over digital attacks for trade secrets. Beijing is now pushing back in an unorthodox way: by organizing a technology forum in Seattle to demonstrate its own sway over the American tech industry. The Sept. 23 meeting is planned to feature China’s Internet czar, Lu Wei, the overseer of China’s restrictions on foreign technology companies. A number of Chinese tech executives, including Robin Li of Baidu and Jack Ma of Alibaba, along with executives from top U.S. tech companies ...

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… So there are a lot of ...

Just over two years ago I decided to spend some time digging into an emerging class of encryption tools that were making a solid run at simplifying the notoriously cumbersome use of PGP. “So I stopped being lazy and have encryption implemented across all of my devices. Now, I have a 4096-bit RSA OpenPGP key, The Chrome extension Mailvelope is handling Gmail encryption, Thunderbird and Enigmail are configured on the Linux box, and IPGMail is setup for the same on my iPhone.” Now I wasn’t looking to implement the strongest security model. I just wanted to see how challenging it would be to implement and use reasonably safe tools across all of my devices. These tools, all of ...
Ion collider produces droplets of primordial goo

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, ...

ScienceAlert... Bluetooth redefines ubiquitous. It’s seemingly everywhere, and nowhere more so than in personal wearable devices such as fitness trackers, smart watches, audio headsets, earphones… you name it. But what if it’s not the best technology for the job? Researchers at the University of California, San Diego in the US have developed a prototype to show off a new wireless communication technique which they say massively outperforms existing wireless tech by using the human body itself to help send data between devices. The researchers call their new method “magnetic field human body communication”. The technique uses the body as a vehicle to deliver ...
Study: Huddling rats behave like 'super-organism'

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 ...

ScienceAlert... A 39-year-old French woman named Martine Richard has won a court case that means that government will need to pay her roughly US$900 a month in disability allowance for at least three years, because of the discomfort caused by her alleged Wi-Fi allergy. Richard claims that she had to quit her job and is confined to a rural barn without electricity because she's so sensitive to electromagnetic waves. Although there are many people who have reported Wi-Fi allergy - or electromagnetic hypersensitivity (EHS) - in the past, she's the first to be officially recognised and compensated for the condition, despite the fact that science says it doesn't exist.

RT... In September, Europe’s Large Hadron Collider (LHC) will smash together sub-atomic particles at nearly the speed of light, an unprecedented experiment that has some of the leading voices in the world of science - and religion - sounding the alarm on the risks involved. CERN is perhaps most famous for its discovery in 2012 of the elusive Higgs Boson [named after British physicist Peter Higgs who predicted its existence in 1964], the so-called ‘God particle,’ which allows other particles to build up mass as they pass through the Higgs field. Today, however, CERN is more famous – or perhaps infamous is the better word - for an upcoming experiment in which ...

Oh, lunar majesty of near-earth orbit, why doth your shine provoke lack of doubt? Awake you keep the owl and wombat, all the while a secret kept, through the blackness ever soaring, only leaving in the morning (usually). Yet over time you seem to morph from something trim to a healthy girth. Early man discovered the secret and since there was no way to keep it we charted your path and labeled your phases until we sang our own self praises for locking down a piece of the skies with just our mind, our thoughts, and eyes. Hmm, waxing poetically about moon phases (see what I did there? The moon waxes and wanes during its phases. Science pun. Never mind.) has gotten me excited to take a ...
