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

Americans traveling abroad are racing to try and get home, up against canceled or fully booked flights."This was our first international trip together, and we were going to spend St. Patrick's Day in Dublin," said Bree Steffen, who lives in San Diego.But for Bree Steffen and Sean Harris, the dream began to unravel while waiting for their connecting flight. "We were in Zürich when we found out about the travel restriction and when the World Health Organization declared COVID-19 a pandemic. So, we were like, 'Oh my God. What do we do?'" said Steffen. The couple tried to book tickets home, but they would've cost upwards of ,000, so Steffen and Harris stuck to the original plan. "We still had a really good time, but it was a lot different than we had pictured," said Steffen. They felt especially safe in the countryside, outnumbered by four-legged friends. But the mood changed in Dublin, where nearly all museums, restaurants, and pubs were closed. "It was tough, it was tough going into a restaurant and knowing that the busiest day for the year for them is now the slowest day of the year," said Harris. "We were supposed to come back on Friday, but everything kept changing hourly, and we were so scared we'd get stuck there, and we can't get stuck there, we had to get back," said Steffen. For days the couple couldn't find a flight; they were either booked or canceled. This week, they ultimately found one through United.At a layover in Newark, New Jersey, passengers were taken off the plane in groups of ten for medical screenings."And then they gave us this card, which has more information on COVID-19 and how to self-quarantine at home," said Steffen. But now at home, they're faced with another hurdle. "Terrifying. I got a realization last night that it's going to be very difficult to sustain a small business while having to be closed," said Harris. While in Ireland, Harris decided to close his business, Serpentine Cider, to stop the spread of coronavirus.Harris was also planning to open a tasting room next month--a decision that will likely be put on hold."We're potentially going to go out of business, and we've been doing really well. Going out of business on something that is not your fault it, it's sad," said Harris.But they're trying to stay hopeful and look forward to the day when they can once again visit Ireland. 2368

A new study shows that women who take birth control pills are less likely to develop the most aggressive types of ovarian cancer. "Among those who used the birth control pills, there were 46 percent lower odds of being diagnosed with ovarian cancer that resulted in death within 12 months of the diagnosis," Jennifer Mongiovi, a PhD student at the University at Buffalo and one of the authors of the study, said.The research also found over a five year period birth control pills reduced the likelihood fatal ovarian cancer by 32 percent. "By taking birth control pills, you can stop as much damage being done to your ovaries from your ovulation, and essentially lower your risk of future damage, such as cancer," Mongiovi said.However, researchers said that before you go out and buy birth control pills, you should consult with your doctor about your medical history and what is appropriate given your circumstances."With anything there are trade offs on both sides. Birth control is a hormone so you are potentially putting yourself at a greater risk of breast cancer. So that's something you definitely need to review your medical history. What essentially is the biggest risk to you," Mongiovi said.The research was conducted at Roswell Park. 1259

American Airlines is extending flight cancellations into mid-August because of the Boeing 737 Max grounding.American, the world's largest airline, decided to extend cancellations from early June through August 19, to help plan ahead for the busy summer travel season. Southwest Airlines last week also extended flight cancellations for 737 Max planes from June until August."Based upon our ongoing work with the Federal Aviation Administration (FAA) and Boeing, we are highly confident that the MAX will be recertified prior to this time," American Chairman and CEO Doug Parker and President Robert Isom said Sunday in a message to airline staff. "But by extending our cancellations through the summer, we can plan more reliably for the peak travel season."Approximately 115 flights a day will be canceled through August 19, representing about 1.5% of the airline's total daily flights, they said.The airline has 24 737 Max jets in its fleet. American has previously said that all flights that were originally scheduled on a MAX plane will not be canceled, with some being substituted with other aircraft.The 737 Max was grounded in March after one of the planes flown by Ethiopian Airlines crashed, killing everyone on board. It was the second accident involving the jet model in less than six months, after another flown by Indonesia's Lion Air crashed last October. The crashes killed 346 people in total.The causes of the crashes are still being investigated, but the focus has been on an automatic safety feature that may have forced the nose of each plane lower when it incorrectly sensed the plane was in danger of going into a stall.Boeing and the FAA said they are working on an upgrade of the 737 Max software to deal with that safety feature.Boeing CEO Dennis Muilenburg said on Thursday the planemaker is closing in on a fix for the software, and a majority of the 50 customers that have ordered 737 Max planes have had a chance to test it using a flight simulator.He added that the update will make the plane "even safer" because it will prevent "erroneous" sensor readings."It's our responsibility to eliminate this risk," Muilenburg said.Muilenburg did not say when 737 Max planes may begin flying again.Boeing announced earlier this month it was cutting the production rate for all of its 737 planes from 52 a month to 42 amid the worldwide grounding. 2379
