Article 1 : Great Scott! How to Get the 'Back to the Future' Self-Lacing Shoes
By
"Power laces — all right!" In "Back to the Future Part II," teenage time traveler Marty McFly (Michael J. Fox) was understandably impressed by a pair of sneakers that conformed to his feet and laced themselves automatically.
It only took 27 years, but Nike has produced those science-fiction kicks and is putting them up for grabs. But there's a catch: Only 89 pairs are available.
The limited-edition release of the 2016 Nike Mag offers the self-lacing sneakers through an online lottery in collaboration with the Michael J. Fox Foundation for Parkinson's Research. Lottery entries can be purchased with a $10 donation to the foundation; 100 percent of all the proceeds will go toward research for a Parkinson's cure, according to a statement released by Nike.
The shoes' big scene in the film lasted less than 30 seconds, but it was long enough for them to make a big impact on moviegoers — and to inspire Nike executives and designers. Nike Mags closely resemble the sneakers that so impressed Marty McFly nearly three decades ago. A system called "adaptive fit" uses sensors to tighten or loosen the shoe to conform to the wearer's foot.
This isn't the first time that Nike has tantalized science-fiction fans with promises of self-lacing sneakers. On March 16, the company announced the forthcoming debut of the Nike HyperAdapt 1.0, declaring in a statement that the shoe would be "the first performance vehicle for Nike's latest platform breakthrough, adaptive lacing."
Nike representatives described a sensor in the sneaker's heel that would detect the wearer's footinside the shoe, triggering the system to adjust the fit.
However, the HyperAdapt's promised release — the 2016 holiday season — would only accommodate Nike+ members, and Nike did not specify how much the shoes would cost or when they would be more widely available.
The lottery for a chance to snap up the new Nike Mag sneaker, on the other hand, is already underway.
If the shoe fits
From Oct. 4 to Oct. 11, residents of the U.S. and Canada can purchase entries to win a pair of Mags on the Nike website or the Nike app. There is no limit to the number of tickets that hopeful entrants can buy, and winners will be notified Oct. 17.
Three additional pairs of Nike Mags will be auctioned off during fundraising events in three cities: Hong Kong on Oct. 11, London on Oct. 14 and 17, and New York on Nov. 12.
Considering Fox was the first to wear the futuristic shoe when it was just a gleam in a special-effects prop master's eye, it seems only right that he would be the first to test out the sneaker in the real world — and Nike delivered the first pair of Nike Mags to Fox in 2015.
"Though it initially shared only a few seconds of screen time with Michael, the idea behind the Nike Mag unlocked something much bigger at Nike," Mark Parker, Nike's chairman, president and CEO, said in a statement. "It sent us down an uncharted path of innovation, but it also opened our eyes to our ability to fight some of the world's biggest challenges. We feel privileged for the opportunity to raise even more awareness for the fight against Parkinson's," Parker said.
Article 2: Send Passwords Securely Through Your Body Instead of Wi-Fi
By
Rather than rely on easy-to-hack Wi-Fi or Bluetooth signals, researchers have developed a system that uses the human body to securely transmit passwords.
Computer scientists and electrical engineers have devised a way to relay the signal from a fingerprint scanner or touchpad through the body to a receiving device that is also in contact with the user. These "on-body" transmissions offer a secure option for authentication that does not require a password, the researchers said.
"Let’s say I want to open a door using an electronic smart lock," said study co-lead author Merhdad Hessar, an electrical engineering doctoral student at the University of Washington. "I can touch the doorknob and touch the fingerprint sensor on my phone and transmit my secret credentials through my body to open the door, without leaking that personal information over the air."
The system uses signals that are already generated by fingerprint sensors on smartphones and laptop touchpads, which have thus far been used to receive input about the physical characteristics of a user's finger.
"What is cool is that we’ve shown for the first time that fingerprint sensors can be re-purposed to send out information that is confined to the body," study senior author Shyam Gollakota, an assistant professor of computer science and engineering at the University of Washington, said in a statement.The researchers devised a way to use the signals that are generated by fingerprint sensors and touchpads as output, corresponding to data like a password or access code. Rather than transmitting sensitive data "over the air" to a receiving device, the system allows that information to travel securely through the body to a receiver that's embedded in a device that needs authentication.
In tests so far, the system worked with iPhones, Lenovo laptop trackpads and the Adafruit touchpad (a trackpad that can be used with computers). The tests were successful with 10 people who had different heights, weights and body types, and worked when the subjects were in different postures or in motion. The on-body transmissions reached bit rates of 50 bps for the touchpads and 25 bps for the phone sensors — fast enough for a simple password or numerical code. Bit rates measure the amount of data that can be transmitted per second, with higher rates representing more data (for instance, a small file rather than a simple password).
On-body transmissions could also be applied to medical devices, such as glucose monitors or insulin pumps, which require secure data sharing to confirm the patient's identity, according to the researchers.
Once they have more access to the software used by fingerprint sensor manufacturers, the researchers aim to continue researching how to provide greater and faster transmission options.
The technology is described in a study that was published online Sept. 12 in the Proceedings of the 2016 ACM International Joint Conference on Pervasive and Ubiquitous Computing.

My articles result from the web site LIVE SCIENCE. My first article speaks about Nike shoes which are able to lace itselfs, these shoes are pulled by a fiction movie "return to the future" but nike exceed this fiction by trading 89 pairs of this shoes at the price of 12.000 $. My second article describes the new mechanism which is about a body passwords which now would not be pirated by a hacker. Today, engineers set up a system with tactile recognisation for WI FI and the bluetooth where the passwords essentially consisted of figures and letters. In conclusion, these engineers managed to delete the written passwords.
