- Russia. where even nature does whatever the fuck it wants to do._niko
- WTF is wrong with Russia?utopian
- Russia is like an endless Fail of day thread.utopian
- that is the melting of permafrost. maybe linked to climate change. or putin's asslowimpakt

- what is information? particles?
the information abounding going particles is returned by a chaotic 'and useless' *** this resolves the information paradox.uan - for all practical purposes the information is lost.

Two supermassive blackholes poised to collide within merging galaxies, 3.5 billion light years away. Will explode with the energy of 100 million supernovae, mostly in the form of gravitational waves. The galaxy(ies) could be completely blown apart by the force of the explosion.

One more step along the long road towards brain-to-brain interfaces
Imagine being able to communicate with others through only your thoughts. No words, no signs are exchanged: only pure information travelling directly from one brain to another. Of course, that is the stuff of dreams and science-fiction flicks: in the real world, the closest that scientists have come to establishing direct communication between brains involves an extremely convoluted apparatus and would take hours to transmit the amount of information you typically exchange in a 2-minute conversation. Nevertheless, research on these brain-to-brain interfaces, as they are called, is valuable because it might one day allow patients with brain damage who cannot speak to communicate using other means. In a recent PLOS ONE report, Andrea Stocco, Rajesh Rao and colleagues from the University of Washington, USA, expand on previous research to demonstrate that BBIs can actually be used to solve problems, albeit in the narrow sense of the experimental laboratory.“Guess what I’m thinking about”
In the experiment, Rao and colleagues built upon previous research from their lab and others to design the brain-to-brain interface. Two participants played a game of “guess what I’m thinking about”, in which the inquirer (the one doing the guessing) asked “yes-or-no” questions to the respondent (the one doing the thinking about). In scientific experiments, the number of parameters must often be kept as low as possible, and this one was no exception: the responder had to think of one object among 8 in a predetermined category (for instance, “dog” among 7 other animals), and the inquirer, who knew the list of objects but ignored which one was selected by the respondent, could only ask three predetermined “yes-or-no” questions (e.g. “Does it fly?”). It is in the way the responder’s answers were communicated to the inquirer that the brain-to-brain interface kicked in.
From brain to brain via EEG and magnetic pulses
To indicate his or her answer, the respondent directed his or her gaze to either of two LED lights, one flashing at 13 Hz coding for “yes”, the other flashing at 12 Hz for “no”. The respondent’s brain responded to the flashing light at the corresponding frequency, and that cerebral activity could be picked up reliably and decoded in real-time by an EEG system. The “yes-or-no” answer was then transmitted to the inquirer’s brain using a transcranial magnetic stimulation (TMS) machine. TMS allows stimulating the cerebral cortex non-invasively by sending sharp magnetic pulses through the scalp and skull, which in turn briefly change the activity of neurons in a given patch of cerebral cortex. When applied to the visual cortex at the back of the head, TMS pulses trigger the perception of brief flashes of light called phosphenes. Here, Rao and colleagues simply controlled the intensity of the TMS pulses so that a “yes” answer would reliably induce the perception of a phosphene by the inquirer, whereas a “no” answer would not.

- Yeah this shit blows my mind (pun intended). They've come a long way since working with rats on this.

Larger than Earth and farther away from Pluto, new evidence suggests a NINTH PLANET lurking at the edge of the solar system.

- Planet X theory rides again.ETM
- surely they can detect it with radar or infrared or something?_niko
- they can detect planets on other star systems, they should be able to use the same method here ie the dimming of stars that it passes in front of_niko
- I'd like to believe that it exists, it would be cool as shit but they're basing this on some exoplanet's erratic orbits? Not sure I buy it._niko
- not that i have any idea of what the fuck i'm talking about_niko
- yeah, that star-dimming technique is for planets much closer to their stars, viewed when the planet comes between us and the star; never happens in this casesarahfailin

A team of researchers from Wake Forest University has created a 3D bioprinting tool that creates large synthetic bone, cartilage, and muscle tissue that is viable for weeks or months at a time when implanted in animals. With a bit more work, the researchers believe these 3D printed tissues could be transplanted into humans, according to a study published today in Nature Biotechology.

- Actually, first directly-imaged exoplanet was around Formhault, taken a few years ago.. http://bit.ly/28X8XD…detritus
- I really don't understand <this one, either - its orbit is about the same as our 'Planet X', yet is 1200LY away.. yet we can't directly image our Planet X?detritus
