Alphabet Inc’s (GOOGL.O) Google has suspended Project Ara, its ambitious effort to build what is known as a modular smartphone with interchangeable components, as part of a broader push to streamline the company’s hardware efforts, two people with knowledge of the matter said.

The move marks an about-face for the tech company, which announced a host of partners for Project Ara at its developer conference in May and said it would ship a developer edition of the product this autumn.

The company’s aim was to create a phone that users could customize on the fly with an extra battery, camera, speakers or other components.

Pediatricians Now Agree: Screen Time Isn’t So Bad for Kids

Beyond ‘turn it off’: How to advise families on media use

When families seek our professional advice on managing technology in their children’s lives, we turn to research-based AAP guidelines that promote positive media use and discourage potentially harmful use.

The most well-known of these guidelines discourage “screen time” for children under age 2 and limit “screen time” to two hours a day for children over age 2 (Abstract/FREE Full Text; Abstract/FREE Full Text). As we know, however, scientific research and policy statements lag behind the pace of digital innovation.

Case in point: The 2011 AAP policy statement Media Use by Children Younger Than Two Years was drafted prior to the first generation iPad and explosion of apps aimed at young children.

Today, more than 30% of U.S. children first play with a mobile device when they still are in diapers, according to Common Sense Media. Furthermore, almost 75% of 13- to 17-year-olds have smartphones, and 24% admit using their phones almost constantly, according to the Pew Research Center.

Building a Single-molecule Transistor from Scratch

Alexander Hellemans

An international team of researchers has demonstrated for the first time that a single molecule can operate as a field-effect transistor when surrounded by charged atoms that operate as the gate. The team published its results in the August 2015 issue of the journal Nature Physics.

The experiments were performed in Berlin at the Paul-Drude-Institut für Festkörperelektronik (PDI), in collaboration with researchers at the Free University of Berlin (FUB), the NTT Basic Research Laboratories (NTT-BRL) in Japan, and the U.S. Naval Research Laboratory (NRL) in Washington, D.C.
