Conscious Brain-to-Brain Communication in Humans Using Non-Invasive Technologies. Human sensory and motor systems provide the natural means for the exchange of information between individuals, and, hence, the basis for human civilization.
The recent development of brain-computer interfaces (BCI) has provided an important element for the creation of brain-to-brain communication systems, and precise brain stimulation techniques are now available for the realization of non-invasive computer-brain interfaces (CBI). These technologies, BCI and CBI, can be combined to realize the vision of non-invasive, computer-mediated brain-to-brain (B2B) communication between subjects (hyperinteraction). Here we demonstrate the conscious transmission of information between human brains through the intact scalp and without intervention of motor or peripheral sensory systems.
Neuroscience. Genetics. Biotech Startup uBiome Aims To Sequence The Bacteria That Call Our Bodies Home. When you look at your body in the mirror, most of what you consider to be “you” actually isn’t you, at least not in a biological sense.
That’s because there are approximately 10 bacterial cells for every single human cell in the body. Startling, yes, but that’s just the tip of the iceberg. Each human body may contain hundreds of thousands of species of bacteria, providing over 350 times the number of genes that is within our own genome, according to an article from Scientific American published last June. As we consider the issues of health and longevity, the big questions that naturally arise are, what exactly are all these bacteria and what relationship does each have with human physiology? E. chromi: Designer Bacteria. E. chromi, a short film about a unique collaboration between designers and biologists has won the best documentary award at Bio:Fiction, the world’s first synthetic biology film festival, held earlier this month in Vienna.E. chromi tells the story of a project uniting designers Alexandra Daisy Ginsberg and James King with a team of undergraduate biology students at Cambridge University.
Using genes from existing organisms, the team designed custom DNA sequences, called BioBricks, and inserted them into E. coli bacteria.The new E. coli—dubbed “E. chromi”—were programmed to express a rainbow of colors when exposed to various chemicals. Ginsberg and King helped the young biologists dream up a variety of possible applications for the invention.For example, E. chromi could be used to test the safety of drinking water–turning red if a toxin is present, green if it’s okay. Fig wasp and fig fruit. Isolated patch of water, trapped under ice, sustains bacterial community. Antarctica's McMurdo Dry Valleys may appear to be one of the least hospitable places on Earth.
They contain a frigid desert where high winds scour the rocky ground, and the only water present is in the form of ice, some of it left over from when the ocean extended into the valley over a million years ago. The area is so inhospitable that NASA has used it to simulate conditions on Mars. So biologists were probably very surprised to find that the area hosts a number of distinct ecosystems. Not on the surface; instead, these communities of bacteria live under the ice, in salty lakes that have been isolated from any external sources of energy or chemicals for anywhere from thousands to millions of years.
The State of Climate Science. Polls show that many members of the public believe that scientists substantially disagree about human-caused global warming.
The gold standard of science is the peer-reviewed literature. If there is disagreement among scientists, based not on opinion but on hard evidence, it will be found in the peer-reviewed literature. I searched the Web of Science, an online science publication tool, for peer-reviewed scientific articles published between January first 1991 and November 9th 2012 that have the keyword phrases “global warming” or “global climate change.” One Astrobiologist's Plan to Save the Search for Alien Life.
A conceptual illustration of the Europa Jupiter System Mission, or EJSM, which consists of an orbiter for both Europa and Ganymede.
Image: NASA/Michel Carroll Jupiter’s moon Europa hides an ocean of water beneath its icy crust that might harbor extraterrestrial life. Unfortunately, big dollar signs have kept alive the fictional decree in Arthur C. Clarke’s Space Odyssey series to leave Europa alone: No robot has ever landed on, drilled into or orbited the chilly world. Meteorites, not comets, may have brought water to Earth. Modern Earth is wet and temperate (last week's heat wave aside), but the early Earth was molten and hostile, meaning water and other volatile substances like hydrogen and nitrogen compounds must have been deposited after formation.
The likely culprits are comets—full of water ice and organic compounds—and meteorites, which were likely more water-laden in the early days of the Solar System. Knowing exactly where Earth's water and organic molecules originated would reveal a great deal about our planet's history and help us understand the environment in which life arose.

BBC Universe – Dark matter: A chunk of the Universe is missing. Mystery of dark matter may be near to being deciphered. (Phys.org)—The universe is comprised of a large amount of invisible matter, dark matter.
It fills the space between the galaxies and between the stars in the galaxies. Since the prediction of the existence of dark matter more than 70 years ago, all sorts of researchers – astronomers, cosmologists and particle physicists have been looking for answers to what it could be. With the latest observations from the Planck satellite, researchers from the Niels Bohr Institute, among others, may be closer than ever to a solution to the origin of the mysterious dark matter. The Planck satellite, which was launched in 2009, has extremely sensitive instruments that can map microwave radiation in the entire sky with great precision. The latest data from the Planck mission reveals unusual radiation from our own galaxy, which open a new direction in understanding the most fundamental properties of the space, time and matter in the Universe.

Dark matter images reveal widest view of dark mystery. 9 January 2012Last updated at 19:07 By Jason Palmer Science and technology reporter, BBC News, Austin, Texas The survey dwarfs the previous largest map, shown at centre alongside the moon for comparison of size in the sky Researchers have released the biggest images yet detailing dark matter, the mysterious substance that makes up 85% of the Universe's mass.
Each image, a billion light-years across, shows evidence of dark matter clumps scattered through the cosmos. The team from the Canada-France Hawaii Telescope inferred the dark matter's existence by the way it bends light. Dark matter’s tendrils revealed. Jörg Dietrich, University of Michigan/University Observatory Munich Dark-matter filaments, such as the one bridging the galaxy clusters Abell 222 and Abell 223, are predicted to contain more than half of all matter in the Universe. A ‘finger’ of the Universe’s dark-matter skeleton, which ultimately dictates where galaxies form, has been observed for the first time.
Researchers have directly detected a slim bridge of dark matter joining two clusters of galaxies, using a technique that could eventually help astrophysicists to understand the structure of the Universe and identify what makes up the mysterious invisible substance known as dark matter. According to the standard model of cosmology, visible stars and galaxies trace a pattern across the sky known as the cosmic web, which was originally etched out by dark matter — the substance thought to account for almost 80% of the Universe’s matter.

David Deutsch on our place in the cosmos. David Deutsch and Quantum Computing. ANNALS OF SCIENCE about David Deutsch and quantum computing. On the outskirts of Oxford lives a brilliant and distressingly thin physicist named David Deutsch, who believes in multiple universes and has conceived of an as yet unbuildable computer to test their existence. Deutsch, who has never held a job, is essentially the founding father of quantum computing, a field that devises distinctly powerful computers based on the branch of physics known as quantum mechanics. Epic study confirms Einstein on space-time vortex around Earth.
Einstein was right: There is a four-dimensional space-time vortex around Earth, and the spin of Earth does twist space-time. That’s according to NASA, in an announcement made 52 years after scientists first imagined how to test Einstein’s theory on space-time – before the technology to test it had even been invented. NASA announced confirmation of the four-D space-time vortex around Earth on May 4, 2011. What does it mean? As Einstein suggested in his general theory of relativity, published in 1916, gravity can be described as the motion of objects following curved lines in space – or rather space-time , as Einstein more accurately depicted it.
The curved lines are caused by the presence of a mass, for example our Earth or sun. NASA’s Kepler Telescope Finds Planet Orbiting Two Stars. 'Habitable' planet discovered circling Tau Ceti star.
