A new study takes a look at how deep the problem of plastics in the ocean goes. Studies have looked at the quantity and spread of plastics in the world’s oceans, and now scientists are getting a better idea of how much of that litter is sinking down to the sea bed.The study, from Australia’s national science agency CSIRO, estimates there is 14 million metric tons of microplastics sitting on the ocean floor. That would be more than 35x as much plastic scientists believe is floating on the surface of the ocean.Microplastics are defined as pieces of plastic that have been worn down by the ocean and other elements into tiny fragments, smaller than 5 millimeters.The team collected samples of deep-sea sediments up to 9,800 feet deep from sites around the Great Australian Bight off the coast of South Australia. The robotic submarine took 51 samples.Scientists found an average of 1.26 microplastic pieces per gram of sediment in the samples.Dr. Denise Hardesty, Principal Research Scientist and co-author of the study, said they were "surprised to observe high microplastic loads in such a remote location.""Our research found that the deep ocean is a sink for microplastics," Hardesty said. "By identifying where and how much microplastic there is, we get a better picture of the extent of the problem."Around 150 million metric tons of plastic are already floating in our oceans -- with an additional eight million tons entering the water each year, according to the World Economic Forum.The researchers say most of the plastic dumped into the ocean likely ends up on the coasts, rather than on the ocean's surface or floor.The samples were taken in the spring of 2017; the study was published in Frontiers in Marine Science on Monday. 1750

A San Diego teenager will use her family's Spring Break trip to Washington, D.C., to advocate for stronger gun control laws.Faith Campbell, a Sophomore at Frances Parker School in Linda Vista, already has a meeting set up with Representative Susan Davis to discuss gun reform. She also has a stack of hand written letters from herself and her classmates to deliver to other area Congressmen and women."A letter is really powerful," Campbell says. "It shows that someone took the time out of their day to write specifically to this person."Campbell says she wrote a letter to Representative Davis after the shooting at Marjory Stoneman Douglas High School in February. Rep. Davis wrote back asking is she would like to meet.Campbell took part in last month's March for Our Lives in San Diego, joining thousands of others to call for stricter gun control laws. But she says she doesn't want the momentum to stall now that the protests and marches are over.Now, Campbell is inviting all of her classmates and fellow teens to write letters. She says she'll deliver them while she's in DC."It doesn't really matter how many letters I get," she says. "It's just the fact that people are writing."She says she'll take any letter written by a teen if they can get it to her by this Friday, April 13th. The letters can be dropped at her father Richard Campbell's office, Procopio Law Firm, at:525 B. Street, Suite 2200San Diego, CA 92101  1452

A relatively new term we're hearing to help stop the spread of coronavirus is “support bubble.”It’s essentially described as a safer way to socialize and support each other. It’s when family members in different houses or close friends agree to socialize in person, but only with each other to limit the risk of infection.“So, when you join a bubble, you're taking on additional risk and the amount of risk you're taking on is that difference between you and the person with the highest risk in the group,” said Cyrus Shahpar, an epidemiologist with Resolve to Save Lives. “So, it’s important to be vigilant and trust those in the bubble.”Part of a support bubble agreement is that everyone practices the same things outside the bubble, including not forming other bubbles. You should also agree to how long the bubble will last. Obviously, the less people, the lower the risk.It’s also a good strategy for families that need help with things like childcare or taking care of an aging relative.Even professional sports teams and other businesses are somewhat following this theory, setting up things like safe hotels and doing things like testing anyone that comes in.“Then, you tell them they can’t leave the place and inside have to be careful about interaction, then you could theoretically say that’s a safer place than outside the hotel,” said Shahpar.Support bubbles could also help limit virus spread even if someone inside the group were to get the virus, because you already know who the close contacts are.“As we navigate through uncharted waters, we don’t know what’s going to happen. We don’t know how long it’s going to last. So, if this helps us maintain our sanity throughout this pandemic, I think it’s a good idea,” said Shahpar.Other countries and some U.S. counties using the support bubble model are seeing success in lowering cases. 1861

A terrifying email scam using stolen passwords and sextortion is trying to scare many out of their money.There are variations of the blackmail threat, but in most cases, a password that someone once used or is still using appears in the subject line of the email.The hackers claim to have "evidence of your secret" after installing malware on adult video sites.The email explains web cameras were hacked and recordings were made of the person watching the pornography.The hackers then demand anywhere from ,000 to ,600 in bitcoin or the video will be released to all contacts, including family members and co-workers."It's a non-negotiable offer, thus please do not ruin my personal time and yours," one hacker wrote. "The clock is ticking.""It's really electronic blackmail," cybersecurity expert Tim Dimoff said. "This is a very well-structured blackmail. Boy, it looks believable."However, it's all a nasty scam. There are no videos and the hackers may have one of your passwords, but they don't have all of your information."If you look in the body of the email, they're not using your name. They're not saying what specific website you might be going to and they don't have a screenshot of you," said Christy Page, the president and CEO of the Better Business Bureau in Akron.Page said more than 130 complaints have reported nationwide through BBB's scam tracker.It's not clear how many of those people gave up the ransom, but it's estimated 0,000 has been paid this year by people frightened by the threat."The fear of embarrassment can be very powerful to get you to part with your money," Page said.Dimoff and Page said the hackers likely used the dark web to buy passwords that were stolen during data breaches and the hackers can be very difficult to track.Page said anyone who receives the email should not pay any money or respond to it.  However, passwords should be changed immediately.In addition, Page said people should consider using a password manager and a web camera cover for extra peace of mind. Some BBB offices offer the covers for free.Consumers who want to find out if their passwords have been compromised can go to the security website Have I been Pwned which collects information on data breaches. 2272

A new study out of a pediatric medical center in Chicago suggests that young children do not only spread COVID-19 more efficiently than adults, but they could be major drivers in the pandemic as schools start to reopen.The report was published at the end of July and examined concentrations of COVID-19 in the nasopharynx, or the upper region of the throat that connects nasal passages. According to the results, children ages 5 and younger who develop mild to moderate symptoms have 10 to 100 times as much COVID-19 in their nasopharynx as adults.“This is a very complex issue involving not just the virus, but everything else,” said Dr. Kwang Sik Kim, director of pediatric infectious disease at Johns Hopkins University Hospital. "We don’t have any real data to indicate to schools what they should do, what is the best recipe they need to follow.”The study raised concerns about the erratic behavior of children and how it could play a factor in the virus’ spread, reading, "Behavioral habits of young children and close quarters in school and daycare settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased. In addition to public health implications, this population will be important for targeting immunization efforts as SARS-CoV-2 vaccines become available.”“Don’t, under any circumstance, even think about opening that school for in-class instruction until you’ve got the virus under control,” said Lily Eskelsen Garcia, president of the National Education Association.Eskelsen Garcia teaches 39 6th-graders in Salt Lake City and says unless the infection rate of a community is below 5 percent, as outlined by the CDC and WHO, school districts should not even consider opening for in-person instruction.Currently, the infection rate in the United States is 7.8 percent."If you open a school before you get the infection rate under control, you will turn that school into the community’s super-spreader,” said Eskelsen Garcia.“Make a decision for today based on the information available today, and then act differently when you have data tomorrow. I think that’s the right approach,” said Dr. Kim. 2170
