scientists built the first quantum


While it's not possible --Chanel Caviar Bags yet -- to "beam" anobject around as in Star Trek, new records for zapping photons instantlyfrom one place to another were set this year. Quantum teleportation has beendone in the lab for some time, but the distances were on the order of a fewyards. In 2012 the new record was 89 miles. In addition to teleporting,scientists built the first quantum Internet. It's onlya beginning, but teleporting photons for miles would enable communications thatcan't be hacked or eavesdropped.

Most of the time when intrepid explorers in fiction meet aliens, theyalways seem to speak perfect English. Doctor Who's TARDIS generates a fieldthat allows travelers to be understood, while the crew of the Enterprise neverseem to need a dictionary. Kim Stanley Robonson's Mars Trilogy featuresone, but he didn't think it would appear until late in the 21st century (thenovels were written in the 1990s). While they won't let you talk to aliens, inthe last year several speech-to-speech translators have managed to reach real consumer devices -- and even one typethat uses your own voice. Most of the apps require aninternet connection, though some, such as Jibbigo, can store their dictionarieslocally. (If they ever add Klingon I'm taking it to the next ComicCon).

As a longtime reader of science fiction, it's always interesting to seehow the visions of writers eventually become real. Take Arthur C. Clarke'sletter to Wireless World in 1945, which details the geostationarycommunications satellite network everyone uses today. The satellites are inwhat is called the "Clarke Orbit." And Isaac Asimov wrote frequentlyabout humanoid robots, which are becoming more common in research Chanel Evening Bags labs --although we have yet to see R. Daneel Olivaw from Asimov's Robot series.

a paralyzed woman was able to control a robotic limb and feed herself directlywith her brain. Continuing work with primates demonstrated that it's possible to make thebrain-computer interface efficient enough to design more realistic movementinto the limbs. The bionic limbs so far don't look anything like theirfictional counterparts, as they are still connected via external electrodes tothe skull. But that dream seems to be a lot closer than it was even a decadeago.

Your list is pretty comprehensive andinteresting to read - I've also been reading sci-fi for decades and have seenmuch of what is envisioned by writers come to reality (in much less time thanwriters can questimate most of the time, ie the Universal Translator). One itemthat I think bears mentioning is the invisibility cloak invented this past yearand all the wonderful and exotic properties of metamaterials coming our way inthe near future. Also, the use of molecular nano-sized machines in medicine liketech-pills you swallow that diagnose and records its passage through the gutand a tiny, little needle used to make repairs inside the eye, driven aroundthe fluid inside the eye and directed with powerful magnets. The pace of changeis too quick in our modern era to choose any one single item as supremelyinteresting over another - lol - there are simply too many.
