Earlier this month, the US Air Force ended height restrictions for pilots in hopes of attracting a more diverse pool of candidates, which the Air Force hopes will result in more female applicants. The new rules went into effect on May 13 for applicants.Previously, pilots were required to stand 64 to 77 inches tall. The Air Force said that medical and operations communities will apply an anthropometric screening process to individual applicants for placement in an aircraft they can safely fly as they pursue a rated track. The Air Force says that its previous requirement eliminated about 44% of female applicants age 20 to 29. “Historically, most of our aircraft were engineered around the height of an average male, not females,” said Lt. Col. Jessica Ruttenber, Air Force mobility planner and programmer and team leader on the Women’s Initiative Team.Government data says that the average American adult woman stands 63.8 inches tall, while the average man in the US stands 69.3 inches. The Air Force had a waiver process that allowed applicants who didn’t meet height requirements the opportunity to be considered, but the Air Force said that the process could have scared off applicants. “While most height waivers were approved under the old system, feedback indicated the entire waiver process served as a barrier, which negatively impacted female rated accessions,” said Lt. Col. Christianne Opresko, branch chief on the Air Force’s Air Crew Task Force and an aerospace physiologist. “It’s hard to determine how many women did not previously apply due to their perception of not being fully qualified or having to pursue a waiver.” 1655

Climate change is putting shellfish at risk as increases in carbon emissions and agricultural runoff are altering ocean ecosystems.Now oyster farmers are adapting before going extinct.“It’s not that they grow more slowly, it’s that they’re less likely to grow at all,” said Todd Van Herpe of Humboldt County Oyster Co.Van Herpe has been farming northern California’s Humboldt Bay for years. Now his livelihood is at risk after scientists say a change in ocean acidification is making it more difficult for oysters to form their shells and ultimately survive.“They’re like anything else; there’s strong one and a weaker one,” Van Herpe said of young oysters. To help protect his product, Van Herpe is getting seed grown in hatcheries. And in this multimillion-dollar industry, any increase in cost is ultimately passed on to you. “We’re going to have to charge our customers more,” Van Herpe said. At Humboldt Bay Provisions, workers are opening up about the change in the industry. “I’ve noticed it’s getting harder and harder to find the freshest oysters,” said one employee.Now this North Coast oyster restaurant is working with more oyster farmers to get this area’s most iconic seafood.“It’s really a source of pride for the people of Eureka and the people of Humboldt County that we have this right in our backyard,” the worker said. Back on the bay, ocean experts are tracking the change in weather conditions. Dr. Joe Tyburczy of California Sea Grant Extension says oysters are suffering because of an increase in carbon emissions and agricultural runoff, which could mean an end to this industry. “If we’re thinking about mass extinctions and radical changes in marine ecosystems this could drive fisheries collapses,” he said.To help keep more oysters alive oyster alive, oyster farmers like Hog Island Oyster Company is now farming oysters in controlled environments.“We’re doing a lot of research here with eel grass and how eel grass can help with manage the acidity of the water through photosynthesis and respiration and taking some of that carbon dioxide out of the air,” Hog Island Oyster Company scientist Juan Avellaneda, PhD said.Making genetic gains could help this seafood and this industry survive. 2232
