The image is concerning  but beautiful; there is a serenity in  Misch 's body language as  he  sings.
"I'm a keen swimmer and love surfing  so that kind of inspired the song  " Misch  tells NPR. "Me and Loyle chatted about ideas for the video and he mentioned he had been talking to Georgia  who had directed some of his previous videos  about a concept they had in mind involving a lake and a dancer. The three of us got on a call to talk through the idea and it all came together. It was a tough one to shoot  but was all worthwhile."

[EX Q]: Sawyer logged off and asked her sister  Mari  31  her partner in a dessert catering company  and their mother  Fran  57  to see whether they had the same problem on their phones.
 Generally Web sites and computers are compromised from within. A hacker can get a Web page or computers to run programming code that they shouldn't. But in this case  it was a security gap between the phone and the Web site that exposed strangers' Facebook pages to the Sawyers. Misconfigured equipment  poorly written network software or other technical errors could have caused AT
T to fumble the information flowing from the Sawyers' phones to Facebook and back.
T could confirm only that the problem occurred on one of the Sawyers' phones  possibly because they had logged off Facebook on the other two before reporting the incident.
 It's unclear how many people were affected by the problem the Sawyers discovered  and whether it was limited to Facebook.
 Usually that means a Web site simply won't load  said Alberto Solino  director of security consulting services for Core Security Technologies. In the Sawyers' case  "somehow they got the wrong user but they could keep using that account for a long period of time. That's what's strange " he said.
 The AP tried to contact two of the people whose Facebook pages were exposed to the Sawyers  but the calls and e-mails were not returned. It's unclear whether they are also AT

[EX Q]: âAt Kernel  our primary aim is to develop technologies to understand and treat neurological diseases in new and exciting ways â  founder Bryan Johnson  said recently at a tech summit. âWe will then interpret the brainâs complex workings in order to create applications towards cognitive enhancement.â
 Johnson  says that the technology should be available for regular use within the next two decades. âI would expect in around 15-20 years we will have a sufficiently robust set of tools for the brain that we could pose any question we wanted â  he  said.
 He  listed examples of the possible applications for the microchips: âFor example  could I have a perfect memory? Could I delete my memories? Could I increase my rate of learning  could I have brain to brain communication?â
 Johnson  is the former founder of Braintree  a payment service provider that was acquired by PayPal in 2013 for $800 million.  Johnson  plunged $100 million of  his  own money into the Kernel project. Thus far  Kernel chips have tested on epilepsy patients to help prevent seizures.
