LaWS is rather unique. Its just a proof of concept test to see if what they will encounter when they put a laser weapon on a ship operationally. This is a step past what they are doing with the X-47b. However, there are no 'X Planes' for lasers, really. LaWS ought to be viewed from that POV. OTOH, HELLADS is a step or two (or more) further along the technology curve than LaWS. Under current Pentagon procurement law, we'll have a laser weapon for ships and/or aircraft by 2020. If we didn't have to go through the insanity of that system, we could have one in a couple years. 2nd, I used to work at HELSTF. I regularly watched pundits claim things we did /that/ day were impossible with the current technology or that there was an easy counter to what we'd done (as if we hadn't tested that first). Talking heads, even ones which have some background in a subject, ought to be taken with a grain of salt. In fact, the BoAS has an axe to grind. Opposition to SDI-like weapons is historical at this point and ought to be taken in that light. Likewise, anything put out there by a defense contractor ought to be taken with an equally large grain of salt, especially one of the beltway bandits.

If you mean 'just started' to mean 'for 20+ years now,' sure. The nomenclature for stars has been around for far, far longer. Exoplanets are given their b-c-d-e etc designation - never a, btw - in the order of discovery, not the order in the planetary system as well. Its not a clusterfuck. Its just a different discipline's rules and they've been consistent for a generation at least.

An exoplanet should NOT be HD189733B. A capital B would denote a star. A lower case b denotes a planet. And, yes, you can have a HD XXXXBb. Alpha Centauri Bb is one of those. Its an S type circumbinary system. For those who are interested, I have a blog which links to the exoplanet papers are they come out, whether its from arxiv or one of the scientific journals.

The words 'ciao' and 'hola' were encoded via electroencephalogram (EEG) and decoyed via transcranial magnetic stimulation (TMS). An error rate of 11 percent was detected on the decoding side and 5 percent on the encoding. Synthetic telepathy is coming. Is the next big thing the 'Thinking Cap?'

anzha writes: After sponsoring a NASCAR racer, DogeCoin's community has wondered, "What next?" The answer is literally "To The Moon!" RevUp Render is sponsoring a DogeCoin promoting micro rover challenge, the Lunar Iditarod. The micro rovers, called DogeSleds, are the size of an smart phone and will be first qualified and then raced here on Earth. The top three competitors will be placed on a Google Lunar X PRIZE team's lunar lander to conduct a short, nine meter race on the moon itself. Registration opens on May 21st and closes July 31st for the first race. The first quarterly race will take place September 5th through September 7th. The event will be public and in the San Francisco Bay Area. All teams, international and American, are welcome, but be forewarned, all fees are in...dogecoin!

+ - U Washington Demonstrates First Brain to Brain Interface 1

Submitted by anzha
anzha writes: Researchers at the University of Washington have successfully demonstrated the first brain to brain interface. One college successfully controlled another's movements. The implications of the demonstration of the technology is pretty profound, even if its in a very early and ideal form. Beginning of Star Trek's Borg? Or David Gerrold's Teep Corps?

+ - Researcher controls colleague's brain from remote location->

Submitted by vinces99
vinces99 writes: University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher. Using electrical brain recordings and a form of magnetic stimulation, Rajesh Rao sent a brain signal to Andrea Stocco on the other side of the UW campus, causing Stocco's finger to move on a keyboard. The researchers believe this is the first demonstration of human-to-human brain interfacing. Rao looked at a computer screen and played a simple video game with his mind. When he was supposed to fire a cannon at a target, he imagined moving his right hand (but didn't actually move it) to cause a cursor to hit the "fire" button. Almost instantaneously, Stocco, who wore noise-canceling earbuds and wasn't looking at a computer screen, involuntarily moved his right index finger to push the space bar on the keyboard in front of him, as if firing the cannon. Stocco, who jokingly referred to the phenomenon as "the Vulcan mind meld," compared the feeling of his hand moving involuntarily to that of a nervous tic.
