12-year-old's invention for detecting plastics in oceans getting national recognition

A 12-year-old girl from Andover, Massachusetts, is getting a big prize and national recognition for her invention to clean up the world's oceans.

Anna Du is one of 10 finalists for the Discovery Education 3M Young Scientist Challenge for her work on an invention that detects microplastics in bodies of water without disturbing plants or animals.

"One day when I was at Boston Harbor, I noticed there was a lot of plastics on the sand," Du said. "I tried picking some up, but there seemed to be so many more, and it just seemed impossible to clean it all up."

Du, a lover of marine animals, decided to take action.

She began work on an underwater device that uses infrared light to detect harmful microplastics in the ocean.

Her invention is now gaining national attention as a finalist in the challenge.

As a finalist, Du will get a chance to work with one of 3M's scientists to take her invention from detecting plastic in her backyard, to detecting it in the world's oceans.

"Science has always been a big part of my life," Du said. "I'm super excited to make something that can actually help the world."

Du wants to go to the Massachusetts Institute of Technology to study marine-related science.

She and the other nine finalists will take part in the final competition in October at the 3M Innovation Center in Saint Paul.

  • The remains of six victims of a deadly volcano eruption in New Zealand have been recovered. Sixteen people were killed on White Island when a volcano there unexpectedly erupted Monday, The Associated Press reported. Eight military specialists recovered six of the eight victims believed to be on the island, and the bodies will be taken to Auckland for identification, CNN reported. Due to toxic gases still being released from the volcano, the team had to wear protective suits and breathing gear to be on the island, the AP reported. The search had to end as air supplies ran low, the New York Times reported. An additional recovery mission is planned to find a tour guide and boat captain who had taken tourists to the island. At least one of them is expected to be in the water, but the other person’s location is unknown, the AP reported. Forty-seven tourists, many from a Royal Caribbean cruise, and guides were on the island when the volcano exploded. Many of the people who survived were burned. Fifteen tourists not from Australia are in burn units across the country with 11 listed as very critical. Thirteen Australians who were part of the tour have all returned to their home country, the AP reported. Skin banks are sending tissues to hospitals to help treat the burns, as medical teams from Australia, Britain and the U.S. travel to New Zealand to help treat patients, the AP reported.
  • A Minnesota man was sentenced Wednesday to more than 24 years in prison in the death of his 13-day-old son. Michael Herkal, 33, pleaded guilty to second-degree murder, nearly 16 months to the day after Apple Valley police responded to an Aug. 12, 2018, medical call for an infant not breathing, WCCO reported. The child died two days later, after doctors determined he had suffered a skull fracture and bleeding in his brain. Herkal was charged initially with felony assault and malicious punishment of a child, but three additional charges of murder were filed after authorities received the autopsy report, KARE11 reported. According to WCCO, Herkal initially told authorities his toddler pulled the newborn off the couch twice but later claimed the baby slipped from his hands and fell onto a coffee table during a diaper change. During his plea hearing, however, Herkal admitted he also shook the infant violently and slapped him, the TV station reported.
  • Major League Baseball announced substantial changes Thursday to its drug use and testing policy, multiple news outlets reported. In addition to removing marijuana from its “drugs of abuse” category – making it the first major US sports league to do so – the organization announced mandatory testing for the presence of opioids, cocaine, synthetic THC, LSD and fentanyl, ABC News reported. Per the policy revisions, players will still be tested for “natural cannabinoids” such as THC, CBD, and marijuana, but punishment for violations will now be treated similarly to those of the alcohol and violence policies, ABC News reported. 'Going forward, marijuana-related conduct will be treated the same as alcohol-related conduct under the Parties’ Joint Treatment Program for Alcohol-Related and Off-Field Violent Conduct, which provides mandatory evaluation, voluntary treatment and the possibility of discipline by a Player’s Club or the Commissioner’s Office in response to certain conduct involving Natural Cannabinoids,” the league, in association with its players union, stated. According to NPR, the policy changes will take effect during 2020 spring training.  “The opioid epidemic in our country is an issue of significant concern to Major League Baseball,” MLB Chief Legal Officer Dan Halem said in a prepared statement, adding, “It is our hope that this agreement - which is based on principles of prevention, treatment, awareness and education - will help protect the health and safety of our Players.” Read more here and here.
  • Seeking emergency mental health assistance could soon be as simple as dialing 988, federal regulators announced Thursday. The Federal Communications Commission formally began the process Thursday to designate 988 as a nationwide suicide prevention and mental health crisis hotline. “The three-digit number is really going to be a breakthrough in terms of reaching people in a crisis,” Dwight Holton, CEO of suicide prevention nonprofit Lines for Life, told USA Today. “No one is embarrassed to call 911 for a fire or an emergency. No one should be embarrassed to call 988 for a mental health emergency.' According to The Wall Street Journal, the new hotline is intended to simplify access to services available currently by dialing 1-800-273-TALK, the existing National Suicide Prevention Hotline. Once operational, dialing 988 would connect callers to the existing hotline and then route them to nearby crisis centers equipped to provide assistance. “We believe this historical and critical effort will turn the tide on reducing suicides and promote mental wellness in the United States,” said a statement from Kimberly Williams, chief executive of Vibrant Emotional Health, the nonprofit that administers the lifeline, The Journal reported.

  • An emergency landing by a single-engine plane snarled traffic Thursday night on Interstate 5 in San Diego, multiple news outlets reported. Ian Gregor, public affairs manager for the Federal Aviation Administration, told KNSD the Cessna 182 made a hard landing on the southbound lanes around 7:15 p.m. Within 30 minutes authorities had re-opened two southbound lanes, KFMB reported. Carlsbad Fire Division Chief Mike Lopez told KNSD a man and a woman were on board traveling from the San Gabriel Airport in Los Angeles to McClellan-Palomar Airport in Carlsbad. According to KFMB, no injuries were reported, and the plane did not strike any motorists. “They did a pretty good job landing this thing,” Lopez told KNSD, adding, “The skill of that pilot, he did a stellar job.”
