As cyclones and droughts are expected to grow in frequency and intensity while global temperatures rise, humankind's closest relatives will become increasingly vulnerable to extinction, scientists say.At climate change's current pace, nearly 40% of the Earth's primates will be threatened by the extreme weather events that accompany rising temperatures, a new study says. And with 60% of primate species already vulnerable to habitat loss and human activity, researchers are pleading that conservationists consider both human and climatic impacts in their efforts.In the study, published in the journal 616

Boeing on Sunday said some of its 737 planes, including many 737 Max aircraft, may have faulty parts on their wings. It's the latest problem Boeing faces as it tries to get its most important and popular airplane, the grounded 737 Max, back in the air.Working with the Federal Aviation Administration, Boeing said it has reached out to airlines that fly 737 planes, advising them to inspect their slat track assemblies on Max and NG aircraft. The 737 NG series includes the 737-600, -700, -800 and -900 planes.Leading edge slats are an aerodynamic control surface that extend from the front of the wing. Some the tracks may not meet manufacturing standards and may need to be replaced, Boeing and the FAA said. They said if the parts are found to be defective, airlines should replace them before returning the planes to service.The faulty parts could fail prematurely or crack. The FAA said a part failure would not bring down a plane, it could damage an aircraft while in flight.Boeing has sent out a service bulletin and the FAA will issue an airworthiness directive requiring airlines to inspect and repair its slat track assemblies within 10 days.The company discovered the problem Friday, when Boeing was meeting with the parts supplier. Boeing employees noticed some of the parts were not heat treated, which led them to believe there might be a safety issue.The development comes as Boeing seeks to get the 737 Max back in the air. The plane was grounded worldwide after a fatal crash of an Ethiopian Airlines jet in March, which followed a fatal crash of a Lion Air jet in Indonesia in October. Crash investigators have focused on an automatic safety feature on the jet as a possible contributor to the crashes.The newly discovered issue affects 148 slat tracks produced by a single supplier, Boeing said. The company said it believes 20 737 Max and 21 737 NG planes may have defective slat tracks. But the FAA advised airlines to check an additional 179 Max planes and 133 NGs to determine if there parts are also faulty. Of the group that needs to be inspected, 33 Max and 32 NG planes are in the United States.The company and the FAA said it has not been notified of any incidents related to the tracks on operating flights, and the fix should take a couple days to complete."We are committed to supporting our customers in every way possible as they identify and replace these potentially non-conforming tracks," said Kevin McAllister, CEO of Boeing Commercial Airplanes, in a statement. 2512

Brace yourself, lovers of diet sodas and sugary drinks. It's more bad news and yet another reason to consider ditching your favorite soda or soft drink.A new study followed more than 450,000 people from 10 European countries for up to 19 years and found those who drank two or more glasses of any type of soda a day had a higher risk of dying from any cause of death than people who drank less than a glass each month. None of the people had cancer, diabetes, heart disease or stroke before their participation.The study, 534

As worries about the spread of the coronavirus confine millions of Californians to their homes, concern is growing about those who have no homes in which to shelter. California has more than 150,000 homeless people, the most in the nation. And that population is considered disproportionately at risk from the virus because of lifestyle and because many have underlying health conditions that make them vulnerable. Gov. Gavin Newsom on Wednesday said 60,000 homeless people could become infected. The governor announced he'll spend 0 million on efforts to prevent the virus from sweeping through that population. 627
