Microsoft Surface Duo could sport peek feature for quick notifications

Along with its new generation of Surface devices, Microsoft announced in October 2019 a new Android-powered smartphone called Surface Duo. As the name suggests, it’s a dual-screen device that folds in and out like a convertible laptop. Though it was recently spotted in a public train, Microsoft is expected to launch the new Surface Duo only towards the end of the current year. In the meantime, a freshly leaked video shows that the device comes with a special ‘peek’ feature for easy notifications.

The leaked video comes to us in the form of a two-part tweet thread from online tipster WalkingCat, who is known to be right about leaks and rumours related to Microsoft’s offerings. The first video demonstrates how the Surface Duo can be opened partially to catch up on notifications without having to open it all the way like a book. In this ‘peek’ mode, only the right half of the right-side display panel lights up to show information such as the time and app notifications, including messages.

The second video shows how this feature might work when the user sees an incoming call. In ‘peek’ mode, only the caller’s name and image appears on the same right edge of the right-side display panel. Opening the display fully makes the incoming call screen fill up completely on the right side, leaving the left with two indiscernible command buttons. When the call is answered, the two displays can be folded out completely to access the earpiece more conveniently.

Not much about the Microsoft Surface Duo’s internals is known so far. It is expected to be powered by a Qualcomm Snapdragon 855 chip.  Each of the two screens on board is said to measure 5.6 inches diagonally, although their resolution is not known. An official teaser video that Microsoft released last year shows quite clearly that the Surface Duo is powered by Android, not Windows 10.  Though the Surface Duo runs Android, we can expect Microsoft to layer it with the Microsoft Launcher.

Artificial intelligence aids in discovery of powerful new antibiotic at MIT

When was the last time you read about the discovery of a powerful new antibiotic, one that was discovered by artificial intelligence no less? Well, you’re about to now. Researchers at the Massachusetts Institute of Technology (MIT) announced recently via MIT News that their in-house deep-learning model had succeeded in identifying a “powerful new drug” that can kill many species of antibiotic-resistant bacteria. Apparently, the new drug squashed many of the bacteria that cause the world's most troublesome diseases in laboratory tests. It also removed infections in two separate mouse models.

In their search for a wholly new compound, MIT researcher James Collins and his team developed new machine learning models that can be trained to analyse the molecular structures of compounds . In particular, they trained one of the models to search for chemical features that make molecules effective in killing the E. Coli. bacteria. During lab tests, they trained the model on approximately 2,500 molecules. They then tested it on a library of around 6,000 compounds. As a result, the model identified one molecule as one that was predicted to have strong antibacterial activity and low toxicity on human cells.

The researchers then decided to name the molecule halicin, after the fictional artificial intelligence character from the popular science-fiction film 2001: A Space Odyssey. They discovered that halicin was effective in killing many isolated, hard-to-kill bacterial strains, including Clostridium difficile, Acinetobacter baumannii, and Mycobacterium tuberculosis. It even worked on mice that were infected with  A. baumannii, a bacterium believed to have infected many American soldiers stationed in Iraq in the past.

“We wanted to develop a platform that would allow us to harness the power of artificial intelligence to usher in a new age of antibiotic drug discovery,” adds Collins. “Our approach revealed this amazing molecule which is arguably one of the more powerful antibiotics that has been discovered.” The researchers at MIT currently plan to use the same model that helped them discover the new drug to create new antibiotics and optimise existing molecules. You can read more about the discovery here.
