Microsoft likely recorded slower earnings and sales growth last quarter as a sharp decline in personal computer sales eroded demand for its Windows software, counteracting some of the demand for its cloud and other businesses serving companies. The Redmond, Wash., corporation's revenue growth is expected to slow to about 10% in the three months through September compared with a year earlier, while its net income is expected to edge up 1%, according to analysts surveyed by FactSet. They predicted the company would report sales of $49.66 billion and net income of $17.36 billion for the period. That would mean last quarter had the slowest revenue growth in more than five years and the lowest income growth in more than two years. The company is scheduled to announce results after the market closes on Tuesday. A weekly digest of tech reviews, headlines, columns and your questions answered by WSJ's Personal Tech gurus.

Summary: New artificial intelligence technology can accurately predict how any chemical is going to smell to humans. A pair of researchers at the University of California, Riverside, has used machine learning to understand what a chemical smells like -- a research breakthrough with potential applications in the food flavor and fragrance industries. "We now can use artificial intelligence to predict how any chemical is going to smell to humans," said Anandasankar Ray, a professor of molecular, cell and systems biology, and the senior author of the study that appears in iScience. "Chemicals that are toxic or harsh in, say, flavors, cosmetics, or household products can be replaced with natural, softer, and safer chemicals." Humans sense odors when some of their nearly 400 odorant receptors, or ORs, are activated in the nose.

Google wants to make the Assistant more powerful, and is announcing today a slew of developer-centric updates that will make it easier to build tools for the digital helper. Three new features in particular are most intriguing: Home Storage, Continuous Match mode and AMP support on smart displays. Google is also releasing a new web-based console and SDK that will make it easier for developers to create for Assistant. These announcements are the largest since the company acquired conversational user experience platform Dialogflow in 2016, according to director of product management Payam Shodjai. With Home Storage, programmers can tap into a pool of information shared by devices in the same household (or, in developer speak, connected on the home graph).
