By now we’re all familiar with Touch ID, the fingerprint authentication security feature introduced with Apple’s iPhone 5s in 2013. The iPhone X replaces Touch ID with a facial recognition system, Face ID, which can be used to unlock your phone, open apps, make purchases in iTunes, and more. Biometric authentication protects our phones, but also introduces new privacy concerns by leaving iPhone users open to the possibility of criminals stealing data or law enforcement accessing it without a warrant. If you have even a few seconds notice before a robbery or unlawful search, you can discreetly and temporarily disable Touch and Face ID on your iPhone; let’s learn how.
How to Temporarily Disable Touch ID or Face ID on Your iPhone
Click the Side Button quickly five times
The Power Off/SOS screen appears, tap the cancel button
Hopefully you’ll never be in a situation where you need to use this tip. But if you must, your biometric authentication features will be disabled, and won’t function again until you’ve entered your passcode in the passcode screen. Just remember, your device is replaceable, but you aren’t! Take precautions ahead of time and make sure you don’t have sensitive data easily accessible on your phone, back up your photos often, and play it safe out there, kids.
Led by Samantha Butler, a UCLA associate professor of neurobiology who is also a part of the Broad Stem Cell Research Center, the study built on previous work published by Butler and her colleagues in September. In the previous study, Butler and her team explored how certain proteins contribute to the development of sensory interneurons in chicken embryos. Their latest research took the principles and information gleaned from the previous study and applied them to human stem cells.
The team added proteins, which establish the structure bone with a signaling molecule, to human embryonic stem cells. This mixture created two separate types of sensory interneurons: dI1 sensory interneurons, which help us determine where our body is in relation to what’s around us in our environment and dI3 sensory interneurons, which give us the ability to feel pressure.
The team also found that they could create the same sensory interneurons mixture by adding signaling molecules to induced pluripotent stem cells. Induced pluripotent stem cells are created from the patient’s own cells, which are then “reprogrammed. This could give researchers the ability to better explore restorative treatments that work with the patients’ body and reduce or eliminate the potential for rejection.
While this area of research is often focused on helping paralyzed patients walk again, Butler’s team is interested in restoring the broader experience of touch. In a press release from the UCLA Newsroom, she said “The field has for a long time focused on making people walk again. Making people feel again doesn’t have quite the same ring. But to walk, you need to be able to feel and to sense your body in space; the two processes really go hand in glove.”
That said, the team does hope their research could prove helpful in developing restorative therapies for patients with paralysis. As Butler put it, “This is a long path. We haven’t solved how to restore touch but we’ve made a major first step by working out some of these protocols to create sensory interneurons.”
While the research marks a major first, there is still a lot of additional research to be done. Butler and her team hope that additional studies will help them exactify mixtures that would allow them to coax stem cells into a variety of different sensory interneurons.
If you see a monkey in Florida, don’t touch it. It seems like pretty basic advice, especially now that scientists have found that more than a quarter of these adorable, feral invaders carry the deadly herpes B virus.
Though at least 25 percent of the population carries the virus — which causes mild disease in macaques, but can be deadly to humans — fewer were actually infectious. The virus lies dormant in nerves in between flare-ups, similar to cold sores in humans. Between 4 and 14 percent of the monkeys released the virus in their spit during their fall breeding season, researchers report in the journal Emerging Infectious Diseases. And the wild monkeys’ poop turned out to be pristine — at least, as far as herpes B was concerned.
A woman who lost her arm over 20 years ago has received the first portable bionic hand, which through a series of tiny electrodes and sophisticated sensors, has restored her sense of touch.
The technology unites the portable bionic hand with a computer that translates the information coming from the artificial fingers into a language the brain can understand, which it then sends back to the body through the electrodes.
This breakthrough is the result of many years of robotic research carried out by teams in Italy, Switzerland, and Germany. Even though she’s central to this amazing innovation, Almerina Mascarello, who was chosen to test the prototype for six months, doesn’t feel like a superhuman. Instead, she told BBC that the prosthetic limb gave her back some of life’s simple pleasures, such as getting dressed or tying her shoes with no help. “All mundane things, really, but important. You feel complete,” she said.
Paolo Rossini, a neurologist at University Hospital Agostino Gemelli in Rome, sees the technology’s potential beyond the day-to-day. He told the BBC that “once you can control a robotic prosthesis with your brain you can think about creating one that allows more complex movements than a hand with five fingers.”
The technology underpinning the new bionic hand was developed in 2014, but at the time, the equipment necessary to support it was so big the prosthetic limb could not leave the lab.
For Dennis Aabo Sorensen, who lost his hand in 2004 in a firecracker explosion, regaining the experience of touch was “fantastic.” He told CattolicaNews that “being able to feel different textures, understanding whether objects were hard or soft and how I was holding them was just incredible.”
Researchers found that Dennis was able to distinguish between a hard, soft or medium object in 78 percent of cases. In 88 percent of cases, he could correctly describe the size and shape of specific objects such as a baseball, a glass, and a tangerine. Three years later, Almerina has been given the same ability just by carrying a small computer in a backpack.
Silvestro Micera, a neuroengineer at EPFL in Lausanne told BBC’s Fergus Walsh: “We are going more and more in the direction of science fiction movies like Luke Skywalker’s bionic hand in Star Wars – a fully controlled, fully natural, sensorized prosthesis, identical to the human hand.”
As exciting as the development is, Almerina had to give back the prototype after the six-month trial. Still, she hopes that once even more portable hands are developed and eventually commercialized, she’ll get to keep one for good.
