A Successful Artificial Memory Has Been Created
The growing science of memory manipulation raises social and ethical

We learn from our personal interaction with the world, and our memories of those experiences help guide our behaviors. Experience and memory are inexorably linked, or at least they seemed to be before a recent report on the formation of completely artificial memories. Using laboratory animals, investigators reverse engineered a specific natural memory by mapped the brain circuits underlying its formation. They then “trained” another animal by stimulating brain cells in the pattern of the natural memory. Doing so created an artificial memory that was retained and recalled in a manner indistinguishable from a natural one.

Monarch Becomes the 1st FDA-Cleared Device for ADHD

NeuroSigma’s Monarch eTNS might be the first device to treat ADHD, but it is one of a growing number of technologies that occupy the burgeoning bioelectronic medicine space.

Monarch is about the size of a cellphone. The device generates a low-level electrical pulse and connects via a wire to a small patch that adheres to a patient's forehead, just above the eyebrows, and should feel like a tingling sensation on the skin.

The system delivers the low-level electrical stimulation to the branches of the trigeminal nerve, which sends therapeutic signals to the parts of the brain thought to be involved in ADHD.[/i]

While the exact mechanism of eTNS is not yet known, neuroimaging studies have shown that eTNS increases activity in the brain regions that are known to be important in regulating attention, emotion and behavior.

World must prepare for biological weapons that target ethnic groups based on genetics, says Cambridge University

Biological weapons could be built which target individuals in a specific ethnic group based on their DNA, a report by the University of Cambridge has warned.

Researchers from Cambridge’s Centre for the Study of Existential Risk (CSER) said the government was failing to prepare for ‘human-driven catastrophic risks’ that could lead to mass harm and societal collapse.

Nanoparticles Will Give You Superhuman Night Vision

Want superhero powers that let you see in the dark just like your cat? In the near future you may be able to—as long as you're not too squeamish to get injections right into your eyeballs.

Researchers from the University of Massachusetts Medical School have discovered a way to give mice the ability to see infrared light, a part of the visible spectrum that we humans simply cannot see, although it's there.

Human 2.0 Is Coming Faster Than You Think. Will You Evolve With The Times?

“Our technology, our machines, is part of our humanity,” author, computer scientist, and inventor Ray Kurzweil once said. “We created them to extend ourselves, and that is what is unique about human beings.” In the past few years, there has been considerable discussion around the idea we are slowly merging with our technology, that we are becoming transhuman, with updated abilities, including enhanced intelligence, strength, and awareness.

Considering Kurzweil’s words is a good place to begin this discussion. It’s no secret that Google has transhumanistic aspirations. In 2011, Steven Levy made this bold statement about the company in the book, In the Plex: “From the very start, its founders saw Google as a vehicle to realize the dream of artificial intelligence in augmenting humanity.” Naturally, it makes sense Google would bring on Kurzweil to be its Director of Engineering in 2012. For years, Kurzweil has been pushing the cultural conversation toward the idea of human transcendence with thought-provoking books: The Age of Spiritual Machines and The Singularity is Near: When Humans Transcend Biology.

Elon Musk unveils Neuralink’s plans for brain-reading ‘threads’ and a robot to insert them

Elon Musk’s Neuralink, the secretive company developing brain-machine interfaces, showed off some of the technology it has been developing to the public for the first time. The goal is to eventually begin implanting devices in paralyzed humans, allowing them to control phones or computers.

The first big advance is flexible “threads,” which are less likely to damage the brain than the materials currently used in brain-machine interfaces. These threads also create the possibility of transferring a higher volume of data, according to a white paper credited to “Elon Musk & Neuralink.” The abstract notes that the system could include “as many as 3,072 electrodes per array distributed across 96 threads.”

Facebook's artificial intelligence robots shut down after they start talking to each other in their own language

Facebook abandoned an experiment after two artificially intelligent programs appeared to be chatting to each other in a strange language only they understood.

The two chatbots came to create their own changes to English that made it easier for them to work – but which remained mysterious to the humans that supposedly look after them.

Earlier this year, Google revealed that the AI it uses for its Translate tool had created its own language, which it would translate things into and then out of. But the company was happy with that development and allowed it to continue.

Another study at OpenAI found that artificial intelligence could be encouraged to create a language, making itself more efficient and better at communicating as it did so.

Google's AI translation tool seems to have invented its own secret internal language

All right, don't panic, but computers have created their own secret language and are probably talking about us right now. Well, that's kind of an oversimplification, and the last part is just plain untrue. But there is a fascinating and existentially challenging development that Google's AI researchers recently happened across.

You may remember that back in September, Google announced that its Neural Machine Translation system had gone live. It uses deep learning to produce better, more natural translations between languages. Cool!

Following on this success, GNMT's creators were curious about something. If you teach the translation system to translate English to Korean and vice versa, and also English to Japanese and vice versa... could it translate Korean to Japanese, without resorting to English as a bridge between them? They made this helpful gif to illustrate the idea of what they call "zero-shot translation" (it's the orange one):

As it turns out -- yes! It produces "reasonable" translations between two languages that it has not explicitly linked in any way. Remember, no English allowed.

But this raised a second question. If the computer is able to make connections between concepts and words that have not been formally linked... does that mean that the computer has formed a concept of shared meaning for those words, meaning at a deeper level than simply that one word or phrase is the equivalent of another?

In other words, has the computer developed its own internal language to represent the concepts it uses to translate between other languages? Based on how various sentences are related to one another in the memory space of the neural network, Google's language and AI boffins think that it has.

The Plan to Use Fitbit Data to Stop Mass Shootings Is One of the Scariest Proposals Yet

In the aftermath of yet another mass shooting in America, loved ones grieve, gun control advocates call for common-sense reforms, and politicians suggest new “solutions” that won’t do anything about guns. These proposals frequently focus on mental health, but a new plan before the White House to monitor “neurobehavioral” predictors of violence isn’t just misguided, it’s terrifyingly dystopian.

Last week, the Washington Post reported that the White House had been briefed on a plan to create an agency called HARPA, a healthcare counterpart to the Pentagon’s research and development arm DARPA. Among other initiatives, this new agency would reportedly collect volunteer data from a suite of smart devices, including Apple Watches, Fitbits, Amazon Echos, and Google Homes in order to identify “neurobehavioral signs” of “someone headed toward a violent explosive act.” The project would then use artificial intelligence to create a “sensor suite” to flag mental changes that make violence more likely.

Fraudsters deepfake CEO’s voice to trick manager into transferring $243,000

It’s already getting tough to discern real text from fake, genuine video from deepfake. Now, it appears that use of fake voice tech is on the rise too.

That’s according to the Wall Street Journal, which reported the first ever case of AI-based voice fraud — aka vishing (short for “voice phishing”) — that cost a company $243,000.
