After eliminating free samples at its locations in March due to the spread of the coronavirus, Costco said on its quarterly earnings call this week that it plans on resuming samples in mid-June. Costco has made significant changes within stores in recent months due to the virus. Costco resumed May 4 after reducing hours, but is now requiring customers and employees to wear masks. Costco has also placed limits on some fresh meats. “We're going to start doing some things in mid-June on a slow rollout basis in sampling,” Costco CFO Richard Galanti said. “I can't tell you anymore, but needless to say it’s not going to be where you go and just pick up an open sample with your fingers. Sampling both food and non-food items are popular.”Galanti said resuming sampling is important in making customers excite to return to Costco stores. Sam’s Club also made a similar decision in March to eliminate samples in stores. 932

An American was possibly exposed to Ebola while recently providing medical assistance in Congo, according to a release from the University of Nebraska Medical Center College of Public Health.The person, who has not been identified, is headed to the Nebraska Medical Center in Omaha for monitoring, the release states, adding the Nebraska Medical Center is home to one of the nation's few dedicated biocontainment units."This person may have been exposed to the virus but is not ill and is not contagious," said Ted Cieslak, infectious diseases specialist with Nebraska Medicine and associate professor of epidemiology in the University of Nebraska Medical Center College of Public Health. "Should any symptoms develop, the Nebraska Medicine/UNMC team is among the most qualified in the world to deal with them."The Democratic Republic of Congo is going through one of the deadliest Ebola outbreaks in history. The outbreak began August 1 and has left more than 300 people dead, with 545 confirmed cases recorded as of Saturday, according to the country's health ministry. Another 48 cases are considered probable.The World Health Organization said protests in Congo over election delays and a deteriorating security situation are interfering with their field teams' ability to carry out Ebola vaccinations in some areas. The American, the Nebraska release states, is not an official patient and is being taken privately to the medical center. Federal, state and county public health officials plan to monitor the person in a secure area not accessible by the public or any patients. Monitoring could take as long as two weeks, the release states.No updates will be given on the person's status during the monitoring period unless needed, the release also states. If it is necessary, though, the individual will be transferred to the Nebraska Biocontainment Unit, where regular updates will be provided.This isn't the first time possible Ebola patients were treated at the Nebraska Medical Center. Nebraska Medicine treated three patients with Ebola in 2014. In 2015, five Americans were monitored at the center after being exposed to the virus in West Africa, but none developed the disease. 2234

A secretive startup backed by Bill Gates has achieved a solar breakthrough aimed at saving the planet.Heliogen, a clean energy company that emerged from stealth mode on Tuesday, said it has discovered a way to use artificial intelligence and a field of mirrors to reflect so much sunlight that it generates extreme heat above 1,000 degrees Celsius.Essentially, Heliogen created a solar oven — one capable of reaching temperatures that are roughly a quarter of what you'd find on the surface of the sun.The breakthrough means that, for the first time, concentrated solar energy can be used to create the extreme heat required to make cement, steel, glass and other industrial processes. In other words, carbon-free sunlight can replace fossil fuels in a heavy carbon-emitting corner of the economy that has been untouched by the clean energy revolution."We are rolling out technology that can beat the price of fossil fuels and also not make the CO2 emissions," Bill Gross, Heliogen's founder and CEO, told CNN Business. "And that's really the holy grail."Heliogen, which is also backed by billionaire Los Angels Times owner Patrick Soon-Shiong, believes the patented technology will be able to dramatically reduce greenhouse gas emissions from industry. Cement, for example, accounts for 7% of global CO2 emissions, 1328
