SAN DIEGO (KGTV)-- On a clear, sunny day in February, the sound of a bell announces the arrival of Naval Commander John C. Witte as he boards the USS Annapolis. He's in charge of the roughly 160 sailors who serve aboard the submarine, one of several boats stationed at Naval Base Point Loma."Submarining takes a lot of mental toughness and these guys will work long hours but they'll do what it takes to get the mission done," Witte told 10News. As you can imagine space is limited on board, nearly every inch is utilized, especially in the command area.

But that's not to say the crew doesn't ever use their eyes. The periscope is still something the submarine crew utilizes regularly. "We may want to look at what other ships are doing we may want to try to observe other navy's activity stuff like that," Witte said. Everyone on board has a specialized skill, but because of the isolation that comes with being underwater for long periods of time, everyone has to take on multiple roles.

When it's time to eat, the culinary specialists use the limited supply of ingredients to make every meal and also bake things like fresh bread and cookies pretty often. "We don't carry a lot of pre-made bread because it takes up too much room so a lot of our bread is made fresh a lot of our cookies are made fresh so its a pretty good," Witte explained.

SAN DIEGO (KGTV): A new study shows that young adults are seeing a spike in deaths from liver disease related to binge drinking. It's especially dangerous in California, where high alcohol content drinks are popular.The study, published this month in the British Medical Journal, says that the number of 25- to 34-year-olds who died annually from alcohol-related liver disease nearly tripled between 1999 and 2016, from 259 in 1999 to 767 in 2016, an average annual increase of around 10 percent.It cites binge drinking as a leading cause, because of rising rates of alcohol consumption between 2002 and 2012.It's especially bad in California, which the study says was among the top five states for those types of deaths.Local experts say the kind of alcohol we drink may be to blame, as craft beers tend to have higher concentrations of alcohol."If someone was having highly concentrated alcohol, then they're consuming more drinks per hour," says Dr. Rohit Loomba, with the UC San Diego Health Liver Center. "That will have detrimental effects on the liver, for sure."The CDC recommends no more than 1-2 drinks per day for "moderate" drinking. Binge drinking is defined as 4 or more drinks over 4-6 hours. Loomba says you may hit the "binge" point in fewer drinks if what you're having is stronger.For example, a Bud Light has just 4.2% alcohol by volume. Craft beers often have 6% or higher, so one craft beer may be as much as 2 or 3 other drinks."That quantity of alcohol intake over years definitely will contribute to higher risk for liver disease," says Loomba.He says people should ask themselves four questions to determine if they are drinking too much:1. Have you ever cut down on drinking? 2. Would you be annoyed if somebody asked you to cut down on drinking? 3. Do you feel guilty after drinking excessively over a weekend? 4. Do you need an "eye-opener" in the morning to get to work?Dr. Loomba says if you answered "yes" to 2 or more of these questions, you should talk to your doctor to discuss treatment.He also says obesity combined with alcohol can lead to more severe liver problems and even death. People with diabetes or who are overweight multiply their risk of the disease."If you're obese, you not only should restrict your alcohol, but you should try to lose some weight as well," says Loomba.The study says the financial crisis may have led to more binge drinking in the past decade, as young adults turned to alcohol to cope with financial stress. Researchers found the rise in alcohol-related deaths overlaps with rising rates of binge drinking from 2002 to 2012 observed across much of the U.S.The good news, according to the study, is that many liver diseases are preventable and reversible."Once you stop alcohol use, you can reverse complications related to it in the majority of cases," says Dr. Loomba. 2882

SAN DIEGO, Calif. -- Tech giants say they will not sell facial recognition software to police departments, for now.It's a tool police departments have been using for years, helping solve everything from property crimes to cold cases and missing people. But there's little oversight over the technology, and critics say it puts our privacy and civil rights in jeopardy.While police often use the software to scan the mug shots of criminals, there's a good chance your photo is also in the system. A 2016 Georgetown Law report found one in two American adults are in a law enforcement face recognition network. In addition to mug shots, social media photos and surveillance videos, many states also allow searches of driver's licenses databases.Critics of the technology also point to inaccuracies in the software.In 2018, researchers at MIT and Stanford University examined three commercially released facial-analysis programs from major technology companies.The analysis showed an error rate of 0.8% for light-skinned men compared to 34.7% for dark-skinned women.Steve Beaty is a professor of computer science at MSU Denver. "It appears these programs have, what we call, biases in them. That they're biased towards certain skin tones, for example, and will make more mistakes with certain types of people than other types of people," said Beaty. He says the bias can occur when the machines are trained. "The computers I don't think have any inherent bias in themselves, but they can only learn from the data sets they're provided with," said Beaty.If a machine sees more photos of white males while being trained, it will be able to identify them more accurately. And while the technology has proven to be a useful-crime fighting tool, a case of mistaken identity can mean an innocent person ends up with police looking into their private lives unnecessarily."I think it's a good idea to take a step back and say what is it we as a society want from our facial recognition technology? That's exactly what Amazon has come out and said," said Beaty. This week, Amazon announced a one-year moratorium on police use of their facial recognition technology, Rekognition. The company is calling on lawmakers to put in place stronger regulations to govern the technology's ethical use.Microsoft also said it will not sell its software to police departments for now, while IBM is abandoning its facial recognition program altogether. "Let's talk about what it means, and have the conversation, and make sure that we as a society, as a country, are comfortable with what the technology is being used for," said Beaty. As companies reevaluate how police officers use their technology, the question remains if the public will do the same. 2737

SAN FRANCISCO (AP) — A Northern California fire department says a telecommunications company slowed its internet communications at a crucial command center set up to help fight one of the state's largest wildfires.KQED radio reported Wednesday that Verizon acknowledged it wrongly limited data speed to the Santa Clara County Fire Department while its firefighters helped battle the state's largest-ever wildfire in Mendocino County three weeks ago, the Mendocino Complex Fire.The county had reached its monthly data capacity under its internet plan with Verizon when the company significantly slowed service.RELATED: 625
