(Phys.org)—Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field that can disable electronics, even a listening device hiding in a prosthetic toe, without knowing where it is.

While these applications remain only dreams, researchers at the University of Maryland have come up with a sci-fi seeming technology that one day could make them real. Using a time-reversal technique, the team has discovered how to transmit power, sound or images to a nonlinear object without knowing the object’s exact location and without affecting objects around it. Their work, “Nonlinear Time Reversal in a Wave Chaotic System,” was published in the Feb. 7 issue of the journal.

“That’s the magic of time reversal,” says Steven Anlage, a university physics professor involved in the project. “When you reverse the ‘s direction in space and time, it follows the same path it took coming out and finds its way exactly back to the source.”

Play it backwards

The time-reversal process is less like living the last five minutes over and more like playing a record backwards, explains Matthew Frazier, a postdoctoral research fellow in the university’s physics department. When a signal travels through the air, its waveforms scatter before an antenna picks it up. Recording the received signal and transmitting it backwards reverses the scatter and sends it back as a focused beam in .

“If you go toward a secure building, they won’t let you take cell phones,” Frazier says, “So instead of checking everyone, they could detect the cell phone and send a lot of energy to to jam it.”

What differentiates this research from other time-reversal projects, such as underwater communication, is that it focuses on nonlinear objects such as a cellphone, or even a rusty piece of metal. When the altered, nonlinear frequency of nonlinear objects is recorded, time-reversed and retransmitted, it creates a private communication channel, because other objects cannot understand the signal.

“Time reversal has been around for 10 to 20 years but it requires some pretty sophisticated technology to make it work,” Anlage says. “Technology is now catching up to where we are able to use it in some new and interesting ways.”

Not only could this nonlinear characteristic secure a wireless communication line, it could prevent transmitted energy from affecting any object but its target. For example, Frazier says, if scientists find a way to tag tumors with chemicals or nanoparticles that react to microwaves in a nonlinear way, doctors could use the technology to………(CONTINUES)

John Titor and Multiverse Theory

Insignia

So….I watched this anime called Steins Gate, great show loved the science and even thought when watching the show “man these guys did their physics homework”. After finishing the series, some time later I accidentally stumbled upon the basis for the show that I thought was just made up or loosely based. Turns out much of the show is based on actual events and physics (supposedly).

My mind was blown…..

I’m still researching John Titor, Frank_J._Tipler, the Omega Point (had the Idea myself before lol), and other time travel stuff…..Lots to read, I let you know what I find, but here’s some of the stuff I’m reading on!

NEW YORK (MYFOXNY)

The Federal Bureau of Investigation has fully rolled out a new biometric identification system that includes facial recognition technology.

The FBI, working with the Criminal Justice Information Services Division, says the Next Generation Identification System is now fully operational.

The system is designed to expand biometric identification capabilities across the country and eventually replace the FBI’s current fingerprint system.

The system includes two new databases.

One, called Rap Back, enables FBI authorized entities the ability to receive ongoing status notifications of any criminal history reported on specific individuals. The bureau says that it will help law enforcement agencies, probation and parole offices, and others greatly improve their effectiveness by being advised of subsequent criminal activity of persons under investigation or supervision.

The second is called the Interstate Photo System. IPS facial recognition service will provide law enforcement agencies across the country an image-searching capability of photographs associated with criminal identities. The Feds say it is a significant step forward for the criminal justice community in utilizing biometrics as an investigative tool.

This latest phase ois only one portion of the FBI’s NGI System. Since phase one was deployed in February 2011, the NGI system has (CONTINUES)

Been a strange time for me this last year, but I’m back now……. Anyways, I have been getting into building RC planes like the ones from http://flitetest.com/ Trying to do some fpv once I get the flying part down! So far I have built and crashed 3 planes, the Versa Wing and the Simple Soarer from flite test, and one of my own design. They all would have flown if I were a better pilot, but I’m not, yet, so only the Simple Soarer really flew.  Hey at least I had fun and they are cheap to build, you can also re-use most of the parts if they aren’t too damaged!

Here are a few pics I took before crashing and rebuilding!

Scientists Make Mice “Remember” Things

That Didn’t Happen

Researchers manipulate mouse neurons to create a false memory; the work could lead to a better understanding of how memories form.

Scientists have created a false memory in mice by manipulating neurons that bear the memory of a place. The work further demonstrates just how unreliable memory can be. It also lays new ground for understanding the cell behavior and circuitry that controls memory, and could one day help researchers discover new ways to treat mental illnesses influenced by memory.

In the study, published in Science on Thursday, the MIT scientists show that they can modify a memory and have a mouse believe it experienced something it didn’t. Susumu Tonegawa, a neuroscientist at MIT, and members of his lab used mice that were genetically modified to allow for certain neurons to be activated with a flash of light; the technique enabled the researchers to activate a memory that caused a mouse to believe it had experienced electrical shocks in a particular box, even though no such thing had happened there. “The process of memory is nothing like a tape recording,” says study co-first author Steve Ramirez. “It’s really malleable and susceptible to the incorporation of new information.”

The results are “really mind-blowing,” says Sheena Josselyn, a neuroscientist at the Hospital for Sick Children in Toronto. “It shows that your memories are really just activities of different cells, and they can take the place of an actual thing that happened by just activating some cells in the brain,” she says. “People have been playing around with this idea for a while, but having a theory and showing it are two different things.”

Advances in neuroscience methods and technology are giving researchers an unprecedented understanding of the biological basis of memories. In recent years, researchers have uncovered details about the molecular and cellular components of memory creation and the electrical language that cells use to recall memories (see “Making Memories” and “A First Step Toward a Prosthesis for Memory”).

More broadly, neuroscientists are increasingly exploring human cognition at its molecular and cellular origins. Someday, this deeper understanding could lead to better or novel treatments, such as memory implants that replace lost memories (see “Memory Implants”) or novel drugs to boost beneficial memory reconsolidation.

Previously, the MIT-based team had shown that it could pinpoint the location and assemblage of cells that carry a memory, and that activating those cells stimulated memory recall in mice. To create the new, false memory, Tonegawa’s team reactivated a mouse’s memory of a safe place while the animal received shocks in its feet, thus transforming the original memory.

First, the team used genetic tricks to label the brain cells involved in the memory of a chamber that was safe and neutral. The next day, they put the animal in a second chamber, a completely different setting. There, the animal got foot shocks while the researchers simultaneously shone light to reactivate the memory of the harmless first chamber. When the animal was put back in the first chamber, it fearfully froze—a clear indication that it remembered getting shocked in that chamber, even though that never happened. “It formed a false memory,” says Ramirez.

One of the long-term goals for the work is to be able to identify new methods for helping patients with cognitive disorders. “It’s not because we want to implant or ‘incept’ some false experience into the human mind, but because it could be useful, eventually, to develop methods to reduce cognitive abnormalities associated with psychiatric diseases, such as the delusions experienced by patients with schizophrenia,” says Tonegawa.

The work also explores…..(Continues)

Here’s an excerpt from  Kenneth Hayworth’s very interesting paper

Killed by Bad Philosophy– Why brain preservation followed by mind uploading is a cure for death

“By the year 2110 such mind uploading will probably be as common place as laser eye surgery is today. No one will be seriously bothered by the philosophical questions that mind uploading provokes today. No one will ask “Sure it will have my memories, it will act like me, and it will even think it is me, but will it really be me?””

WTF are all those cancer research people doing if a 15 year old beats them to the punch?

By Maria Cramer

 

The scenario had been carefully planned: A terrorist group prepared to hurt vast numbers of people around Boston would leave backpacks filled with explosives at Faneuil Hall, the Seaport District, and in other towns, spreading waves of panic and fear. Detectives would have to catch the culprits.

Months of painstaking planning had gone into the exercise, dubbed “Operation Urban Shield,” meant to train dozens of detectives in the Greater Boston area to work together to thwart a terrorist threat. The hypothetical terrorist group was even given a name: Free America Citizens, a home-grown cadre of militiamen whose logo would be a metal skull wearing an Uncle Sam hat and a furious expression, according to a copy of the plans obtained by the Boston Globe.

But two months before the training exercise was to take place, the city was hit with a real terrorist attack executed in a frighteningly similar fashion. The chaos of the Boston Marathon bombings disrupted plans for the exercise, initially scheduled for this weekend, forcing police to postpone. Now officials must retool aspects of the training.

“The real thing happened before we were able to execute,” said a law enforcement official with direct knowledge of the planned exercise. “We’ve already been tested.” (Continue)

Pyrodin’s Note- Isn’t it weird that the officials are often running a “drill” before the “terrorists” attack the same way they were planning to drill for?

So, I read a book called “Patient Zero”  by Jonathan Maberry. This book features some interesting tech that the author claims actually exists, one of these items is the Water Stun Gun-

Here is a clip from MythBusters  showing their attempts (half ass attempts in my opinion) at making one of these.

In the video they never really get it to work,  but if you were to use a Non-Newtonian fluid,  shampoo for example, add a salt or other conductive agent and it might work

or maybe protein polymers in water

( Stringy and bobbly spit  is a good example)

so the beading effect could be overcome by linking the beads  and making a conductive path.
