RT... UK scientists have applied for permission to genetically modify human embryos for the first time as part of research into the earliest stage of human development. Stem cell scientists at the Francis Crick Institute in London have asked the government’s fertility regulator for a license to perform controversial genome editing on human embryos. Researchers hope the experiments will help scientists to learn more about genes in the first few days of human fertilization. Chinese researchers became the first researchers in the world to announce they had altered the DNA of human embryos in April. The news prompted a fresh debate over the ethics of cheap and simple new genetic ...

NaturalNews.com Ecologists refer to bees and a few other select organisms as keystone species. This term is analogous to the keystone of an arch. Remove the wedge-shaped stone at the top, and the entire structure collapses. Bees are a keystone species because they are the world’s primary pollinators and are therefore crucial to the environment. While Monsanto claims bees only pollinate about a third of the world’s crops, others estimate their contribution to be closer to 90%. But the startling decline of the bee population isn’t just threatening our crops, it is also threatening varied and diverse wild plants across the globe that provide food for countless animal ...

The term “lovebird” has a new meaning. A recent study reveals that birds can fall in love. According to Nature World Report, Malika Ihle and her team of researchers from the Max Planck Institute for Ornithology in Germany found that birds that ended up choosing their own mates had 37 percent more offspring than those that were paired up. The researchers used 160 zebra finches for the study, allowing 20 females to choose freely among 20 males. After the birds paired off, half were left alone while the other have were broken up and paired with other “broken up” birds. They found that birds that paired up on their own had higher reproduction rates than the ones paired ...

Want... The People's Liberation Army may eventually equip its main battle tanks with electric reactive armor to prevent damage from anti-tank weapons, reports China's Global Times. Electric reactive armor is usually made of two electrical plates separated by an insulator to make a high-power capacitor. When a tank using the armor is hit by an incoming object such as a rocket or missile, it will discharge electricity from the capacitor to vaporize the object. The discharge is claimed to be powerful to turn the incoming object into plasma, said the report. From the Chinese perspective, the electric reactive armor is the best available defensive technology for tanks in the world and ...

ScienceAlert... Boeing has announced that the ABS–3A, the world’s 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 ABS–3A 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 ...

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 ...

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 ...

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

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 ...

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 ...
