SEATTLE (AP) — Researchers say a London man appears to be free of the AIDS virus after a stem cell transplant. It's the second such success including "Berlin patient" Timothy Ray Brown.Such transplants are dangerous and have failed in other patients. The new findings were published online Monday by the journal Nature.The London patient has not been identified. He was diagnosed with HIV in 2003. He developed cancer and agreed to a stem cell transplant to treat the cancer in 2016.His doctors found a donor with a gene mutation that confers natural resistance to HIV.The transplant changed the London patient's immune system, giving him the donor's HIV resistance. 674

SCOTTSDALE, Arizona — From pre-made salads and sandwiches to ready-to-make meal kits and online ordering, the grocery store has become a conveyor belt of innovation the last few years.It’s time to throw another piece into the basket — driverless delivery. Kroger, the Cincinnati, Ohio-based grocery chain that operates Fry’s Food Stores, announced Thursday, Aug. 16, that it will begin testing its driverless delivery program in Scottsdale, Arizona. In June, the company said it was exploring the program and had partnered with Nuro, a company founded in 2016 that makes unmanned vehicles, but had not named where they would be tested.Now we know where.Starting Thursday, the program will only be available to those living in the 85257 zip code and within two miles of the Fry’s grocery store at 7770 E. McDowell Road in Scottsdale (near Scottsdale and North Hayden Roads).Here are a few things you need to know:WHAT IS IT?Forget going to the grocery store and walking the aisles to grab the milk, eggs and cheese. Under the test program, customers will be able to order their groceries via the Fry's Food Store app and website and have them delivered to their home by one of Nuro’s ten unmanned Toyota Prius vehicles.Each vehicle will deliver the groceries to a home’s curbside and can deliver up to 15 bags of groceries, said Pam Giannonatti, corporate affairs manager with Kroger.HOW SAFE IS IT?“Safety is Nuro’s top priority. They are relentlessly focused on ensuring their vehicles are not just good neighbors, but among the safest on the road,” Kroger said in a statement. “Their vehicles and the autonomy systems undergo extensive testing including a wide range of critical safety scenarios that require immediate response to prevent harm.”During the test, Kroger said each vehicle would have a safety test driver with it.HOW DOES IT WORK?Starting Thursday, Aug. 16, those living within the 85257 zip code can order groceries from the Fry’s Food app or website, https://www.frysfood.com.They can be delivered by one of Nuro’s vehicles that same day or the next day depending on availability.The delivery fee is .95 per order. There is no minimum order amount.“Arizona is home to some of the most innovative autonomous vehicle testing,” said Dave Ferguson, Nuro’s co-founder, in a prepared statement. “We’re proud to contribute and turn our vision for local commerce into a real, accessible service that residents of Scottsdale can use immediately. “We welcome innovative technology that can benefit the lives of Scottsdale residents. We feel this partnership holds tremendous potential and promise, and offers our residents real, not-yet-experienced convenience for everyday routines," Scottsdale Mayor Jim Lane said in a statement.Some of Arizona's top leaders, including Gov. Doug Ducey, have been supportive of autonomous technology.Uber began testing its self-driving technology in Arizona in February 2017, but shut down its operations earlier this year after one of its vehicles was involved in a deadly crash with a pedestrian.Waymo, a subsidiary of Alphabet Inc., the parent company of Google, is also testing self-driving vehicles in Arizona.Kroger did not say how long the pilot test would last nor if — or when — more locations would be added. 3291

SEATTLE (AP) — Scientists say an orca who raised worldwide concern when she carried her dead calf for 17 days and more than 1,000 miles almost two years ago is pregnant. The Seattle Times reports Southall Environmental Associates scientist John Durban and marine mammal research director for the nonprofit SR3 Holly Fearnbach recently finished recording drone images of the endangered southern residents and discovered pregnancies amid the J, K, and L pods. According to SR3, whale pregnancies typically last 17-18 months.Pregnancies are not unusual but Tahlequah's pregnancy carries special meaning for a region that grieved the death of her calf along with her. The southern residents are struggling to survive, and most pregnancies are not successful.SR3 says the unsuccessful pregnancies are due to lack of food and nutrition and there are only 73 whales in population. 881

SAN FRANCISCO, Calif. (AP) — Gov. Gavin Newsom says California is turning the corner in its fight against the coronavirus pandemic. He cited a significantly lower number of confirmed new cases as California begins to clear backlogged cases caused by a technical error. Newsom says he's also encouraged by the downward trend in hospitalizations, which have fallen 21% in the past two weeks. Dr. Roger Lewis, director with the Los Angeles County Department of Health Services, says there’s been “a clear decline” in hospitalizations there. California reported 180 additional deaths from the virus Wednesday, bringing the state's coronavirus deaths to more than 10,600. 674
