Data breach at Mass. General involves 4,300 dental patients

A data breach at Massachusetts General Hospital has exposed the personal information of about 4,300 dental patients, the hospital said Wednesday. Unauthorized people were able to access patients’ names, dates of birth, Social Security numbers, and information about their dental appointments. The information was stored through Patterson Dental Supply Inc., a software vendor that helps manage dental practice information at Mass. General. The hospital said it learned in February that “an unauthorized individual gained access to electronic files.’’ Mass. General did not notify patients right away because law enforcement officials asked the hospital to withhold notice while they investigated, the hospital said. Patterson Dental Supply has taken steps to enhance security following the breach, the hospital said. Patient information has been breached or mistakenly exposed at other hospitals over the past few years, including Beth Israel Deaconess Medical Center, Boston Children’s Hospital, and St. Elizabeth’s Medical Center. — PRIYANKA DAYAL MCCLUSKEY

Largest diamond found in more than 100 years fails to sell

The biggest diamond found in more than 100 years failed to sell at an auction in London after the highest bid of $61 million didn’t meet the company’s minimum selling price. Based on a diamond sale in May, the 1,109-carat diamond that’s called Lesedi la Rona, or ‘‘our light’’ in the Tswana language spoken in Botswana, might have sold for about $86 million, which would have made it the most expensive rough gem on record. Yet the $61 million bid didn’t reach the so-called reserve price at a Sotheby’s auction on Wednesday night. The giant stone was unearthed at Lucara Diamond Corp.’s Karowe mine in Botswana. The company is gaining a reputation for producing the world’s biggest and best stones and sold an 813-carat diamond for $63 million in May, a record, to Nemesis International DMCC, a Dubai-based rough-diamond trading company. — BLOOMBERG

House passes noncompete bill

The state House of Representatives voted 150-0 on Wednesday to approve a bill that would impose strict new limits on noncompete agreements, a move largely aimed at making Massachusetts more appealing to startups and skilled tech workers. The bill was the result of a compromise brokered by House Speaker Robert DeLeo and his leadership team. DeLeo aimed to balance the interests of big-business groups whose members rely on noncompetes and the startups and their champions who want to see them go away completely. Among other things, the bill would restrict noncompetes to no more than one year in length and would require employers to pay workers half their salary until the noncompete expires, a provision known as “garden leave,’’ or some other mutually agreed upon compensation. A wide range of hourly workers would be exempt from noncompetes, and recruits would need to be clearly notified if they would be subject to a noncompete before starting their new jobs. The issue now heads to the Senate. Any major differences between the House and Senate bills would need to be negotiated before lawmakers adjourn from formal sessions for the year on July 31. — JON CHESTO

Amazon to sell phones again

Amazon is back in the phone business — sort of. After its own Fire phone flopped, Amazon is selling special editions of other manufacturers’ phones at a $50 discount. They’ll come with ads on the lock screen and lots of Amazon apps on the home screen. You can hide those apps, but won’t be able to uninstall them. Amazon.com Inc. is touting the discount as a benefit of its $100-a-year Prime loyalty program. Membership is required, and Amazon figures that those customers will appreciate having single sign-in access to Amazon’s various services without having to download about 10 individual apps for video, Kindle e-books, music and, of course, shopping. — ASSOCIATED PRESS

Toyota to recall 3.37 million cars over air bags, emissions

Toyota on Wednesday announced it would recall 3.37 million vehicles worldwide over air bag and emissions defects. The automaker said that welds that connect side curtain air bags could deteriorate over time, causing the devices to inflate without cause. The recall covers Toyota Prius models from 2009 through 2015 and Lexus CT200 models from 2010 through 2015. The total accounts for 1.4 million vehicles, 482,000 of them in the United States, Toyota said in the announcement. Additionally, 2.87 million vehicles internationally are being recalled for possible cracks in the fuel tank, Toyota announced. Some Prius models are affected by both defects, the company said, as are the Auris, Corolla, Zelas, Lucas, and Lexus HS250h and CT200h manufactured from 2006 through 2015. The latest air bag issues are unrelated to another recall for vehicles from multiple automakers that have Takata air bags, Toyota said. They are made instead by Sweden-based Autoliv, which said in a statement that it is cooperating with Toyota and American and Japanese authorities. — WASHINGTON POST

Kellogg to open cereal cafe in New York as sales slump

Kellogg is opening a cafe in New York as it pushes to reinvent cereal’s soggy image. The company based in Battle Creek, Mich., says bowls will cost $6.50 to $7.50 and combine cereals like Special K and Frosted Flakes with ingredients like pistachios and lemon zest. The move comes as Kellogg Co. has suffered declining cereal sales in the United States, with people reaching for a growing array of breakfast options. To boost sales, the company is also trying to market cereal as a night-time treat and on-the-go snack. Kellogg says its cereal cafe, located on Broadway, between 48th and 49th streets, will open July 4. The cafe will also serve ice cream dishes, juices, and coffees. — ASSOCIATED PRESS

Iconic Watergate building to be sold

Washington’s Watergate office building, made famous by the political scandal that brought down President Richard M. Nixon, is under contract to be sold, according to financing documents obtained by Bloomberg. New York real estate investment firm Steinbridge Group and Dallas-based Lincoln Property Co. are buying 2500 and 2600 Virginia Ave. NW, also known as Watergate East, for $107 million, according to the document by brokerage Holliday Fenoglio Fowler LP. The 12-story, 270,000-square-foot office property in the Foggy Bottom neighborhood, about a mile west of the White House, is part of a six-building complex that also includes co-op apartments and a hotel that has just been renovated. Burglars in 1972 broke into the office building’s 11th floor, then the headquarters of the Democratic National Committee, a crime that ultimately led to the unraveling of the Nixon presidency. — BLOOMBERG
