Analog DNA circuit does math in a test tube: DNA computers could one day be programmed to diagnose and treat disease
A team of Duke University researchers have demonstrated the creation of synthetic strands of DNA that, mixed together in the right concentrations in a test tube, can create analog circuits able to add, subtract, and multiply as they form and break bonds. Rather than voltage, DNA circuits use the concentrations of specific DNA strands as signals. The technology takes advantage of DNA’s natural ability to zip and unzip to perform computations. Besides addition, subtraction and multiplication, the researchers are also designing more sophisticated analog DNA circuits that can do a wider range of calculations, such as logarithms and exponentials.
The hope is that, in the distant future, such devices could be programmed to sense whether particular blood chemicals lie inside or outside the range of values considered normal, and release a specific DNA or RNA (DNA’s chemical cousin)that has a drug-like effect.

WhatsApp says it’s going to start giving user data to Facebook
Ever since Facebook acquired the WhatsApp messaging app two years ago, users have worried about their privacy. WhatsApp has just announced it will begin sharing some user data with its parent company, such as users’ phone numbers, so that Facebook can tailor its friend suggestions by mapping users’ social connections between the two services. It’ll also help Facebook serve up more relevant ads. Analytics data from WhatsApp will even be used by Facebook to track usage and deter spam.

Canon 5D Mark IV shoots 4K video, 30.4-megapixel stills, has built-in Wi-Fi and GPS
The just-released Canon 5D Mark IV DSLR takes Canon into the realm of 4K video while increasing the size of stills to 6720 x 4480 pixels. A new 30.4-megapixel dual pixel sensor improves focus speed, Canon says, and can capture two images simultaneously with slight different focus points that can be adjusted in post-processing. The Canon 5D dates to 2005 f0r stills, and to 2008 and the 5D Mk II for video. With the Mark IV, video is bumped to to DCI 4K (4096 x 2160 pixels) at 24 or 30 frames per second for up to 30 minutes per clip. There’s also Full HD video (1920 x 1080) at up to 60 fps, or HD (720p or 1280 x 720) at up to 120 fps for quarter-speed slow motion.

Android Nougat rollout allegedly hampered by Snapdragon 800
Many older smartphones dating 2014 and earlier are being left out of the Nougat party simply because Qualcomm won’t be releasing updates to the graphics driver of the Snapdragon 800 or 801 powering those devices. Qualcomm, for one reason or another, has supposedly decided not to release updated drivers for the Snapdragon 800 and Snapdragon 801 processors, which happen to drive practically all 2014 flagship devices, and even some 2015 ones that decided to stay off the ill-fated Snapdragon 810. And, for technical reasons still not clear, such updated drivers are supposedly required to run Android 7.0 Nougat.

Apple plans to focus on social by making a Snapchat-like video app
Apple is getting into social networking again, but this time it’s not about music. Instead, it’s developing a video-sharing and editing app for iPhone and iPad. The ultimate hope is that people would use the app, which is being built by the same folks who built iMovie and Final Cut Pro, to create the content to share with other social networks.
So far reports said that Apple is not clear-cut on when (or even if) this app will launch, or whether or not it will live as part of iOS or as its own standalone app.
