In this video series the Galactic Public Archives takes bite sized looks at a variety of terms, technologies, and ideas that are likely to be prominent in the future.
In this entry, we take a look at the rapidly developing technology of Brain to Machine interfaces.

History has shown us that only violence or huge disasters tend to reduce inequality. Which is frightening on it’s own.
The Great Leveller: Violence and the History of Inequality from the Stone Age to the Twenty-First Century By Walter Scheidel. Princeton University Press; 504 pages; $35 and £27.95.
AS A supplier of momentary relief, the Great Depression seems an unlikely candidate. But when it turns up on page 363 of Walter Scheidel’s “The Great Leveler” it feels oddly welcome. For once—and it is only once, for no other recession in American history boasts the same achievement—real wages rise and the incomes of the most affluent fall to a degree that has a “powerful impact on economic inequality”. Yes, it brought widespread suffering and dreadful misery. But it did not bring death to millions, and in that it stands out.
This is big: Is the Singularity a step closer?
Tesla Inc founder and Chief Executive Elon Musk has launched a company called Neuralink Corp through which computers could merge with human brains, the Wall Street Journal reported, citing people familiar with the matter.
Neuralink is pursuing what Musk calls the “neural lace” technology, implanting tiny brain electrodes that may one day upload and download thoughts, the Journal reported. (on.wsj.com/2naUATf)
Musk has not made an official announcement, but Neuralink was registered in California as a “medical research” company last July, and he plans on funding the company mostly by himself, a person briefed on the plans told the Journal.
Some parts of the body – including the tissues of the brain and testes – have long been considered to be completely hidden from our immune system.
Last year scientists made the amazing discovery that a set of previously unseen channels connected the brain to our immune system; now, it appears we might also need to rethink the immune system’s relationship with the testes, potentially explaining why some men are infertile and how some cancer vaccines fail to provide immunity.
Researchers from University of Virginia School of Medicine discovered a ‘very small door’ which allows the testes to expose some of its antigens to the immune system without letting it inside.
(Tech Xplore)—A team of researchers at the University of Wisconsin has developed a pair of glasses that allows the wearer to have tetrachromatic vision. In their paper uploaded to the arXiv preprint sever, the group describes the inspiration for their glasses and explain how they work.
Humans have three types of cone cells in the back of the eye to differentiate color. Some react to blue, some to green and some to red. The cones do their work by responding to the difference in wavelength of the incoming light. Such vision is known as trichromatic. In this new effort, the researchers have found a way of fooling the brain into seeing as if there were a fourth type of cone, by wearing glasses with two types of filters. The result is tetrachromatic vision.
To create the glasses, the researchers fashioned two types of filters, one for each eye. The filters remove some parts of the blue light spectrum. But the filters each remove a different part. When the filters are fitted into a frame and worn like regular glasses, the wearer is able to see colors that are normally hidden—metamers. In a sense, it is rather the opposite of what occurs with people who are color blind. They might see blue and red as the same, even though there is more light information there. Adding spectrum identification to color blind eyes allows for seeing more of what is already there. With the new combined filter system, a person is able to look at what appears to be an object that is all the same color, such as purple, and see more colors in it—those normally hidden metamers.
“Yep, transforming health care and telepathy, those are the items on her to-do list. Jepsen plans to achieve both goals with a cheap wearable device that her engineers are now tinkering with in the lab. And then there’s the side benefit of reinvigorating the tired consumer electronics industry, which Jepsen thinks is due for the next big thing.
Jepsen was at SXSW to give a talk about Openwater, her new startup. While the company is still conducting R&D to decide on its first products, Jepsen feels the need to speak out now about what she’s building and how she thinks her technology could radically change society. She wants to give people fair warning and time to think about what’s coming. “I know it seems outlandish to be talking about telepathy, but it’s completely solid physics and mathematical principles—it’s in reach in the next three years,” she says.
Plus, she’s sick of stealth mode. “I haven’t been able to to talk about what I’ve been doing for five and half years while I was at Google and Facebook, and I don’t think secrecy is useful,” she says. She left Facebook in August, and in September she filed patents for her Openwater technology, which she expects to be issued any day now.

JUDY WOODRUFF: For decades, researchers have worked to create a better and more direct connection between a human brain and a computer to improve the lives of people who are paralyzed or have severe limb weakness from diseases like ALS.
Those advances have been notable, but now the work is yielding groundbreaking results.
Special correspondent Cat Wise has the story.
