Scientists are exploring mysterious “blue holes” that form at the bottom of the ocean off Florida’s Gulf Coast.The blue holes are underwater sinkholes that vary in size, similar to sinkholes you can see on land, according to the National Oceanic and Atmospheric Administration. They are diverse biological communities full of marine life, like corals, sponges, mollusks, sea turtles, sharks, and more.“Underwater sink holes, springs, and caverns are karst (calcium carbonate rock) features that are scattered across Florida’s Gulf continental shelf,” said NOAA.NOAA says little is known about blue holes due to their lack of accessibility and unknown distribution and abundance. Openings can be several hundred feet underwater and many openings are pretty small.“In fact, the first reports of blue holes did not come from scientists or researchers, but actually came from fishermen and recreational divers,” wrote NOAA.Last year, a team of scientists explored one blue hole, called “Amberjack Hole,” about 30 miles off Sarasota’s shoreline. NOAA says the exploration of the hole was the team’s most detailed blue hole investigation to date. Divers and a “benthic lander” were deployed to the bottom, 350 feet down.NOAA says the team collected 17 water samples from just outside the hole down to the bottom and collected four sediment cores at the bottom. They also discovered two dead but intact smalltooth sawfish, an endangered species, at the bottom of the hole. One of the animals was recovered to undergo a necropsy.But next month, crews plan to explore an even bigger hole, called “Green Banana.”The rim of the “Green Banana” is 155 feet below the sea surface and the bottom is at a depth of approximately 425 feet, according to NOAA.“The configuration of the hole is somewhat hourglass shaped, creating new challenges for the lander deployment and water sampling,” said NOAA.From these missions, scientists are hoping to learn the following:Whether the submersed sinkholes are connected to Florida’s groundwater or if there is groundwater intrusion into the Gulf of MexicoIf a particular blue hole is secreting nutrients and thus affecting an area’s primary productionWhether microenvironments harbor unique or new species of microbesIf the Amberjack site should become a protected area 2301

SEATTLE (AP) — One of two people hit by a man who drove his car onto a closed Seattle freeway and into a crowd protesting police brutality has died. A hospital spokeswoman said 24-year-old Summer Taylor of Seattle died Saturday evening at Harborview Medical Center.

SANTEE, Calif. (CNS) - Authorities asked for the public's help in finding the driver of a minivan suspected of following a nine-year-old boy along a street in Santee and trying to entice him to get into the van.The boy told San Diego County Sheriff's Department deputies he was walking alone on Trailridge Avenue, between Hightail Drive and Weston Road, about 5 p.m. Wednesday when the driver asked him to get into the van and go to a community pool with him. The boy refused and walked away and the driver left the area, according to Sgt. Joseph Jarjura.The driver was described as a white man, between 18-20 years old with short black hair, wearing a light-colored T-shirt, Jarjura said, adding a woman may have been in the passenger seat, but no description was available.The minivan was possibly a black Dodge Caravan with tinted windows and black rims.Anyone with information was asked to call the department at 858-565-5200. 938

SAN FRANCISCO, Calif. – Airbnb announced Thursday that it’s banning all parties and events at the listings on its website to comply with limits on gatherings during the coronavirus pandemic.The San Francisco-based company says the party ban applies to all future bookings on Airbnb and it will remain in effect indefinitely until further notice.Additionally, Airbnb says the occupancy at its listings will be capped at 16 people. Though, the company says it’s considering a potential exception process for specialty and traditional hospitality venues, like boutique hotels.“We also understand that 16 is not a magic number, and issues can occur with groups of any size,” wrote the company. “To be clear, we are not sanctioning smaller gatherings with this policy and all community members are expected to comply with local health restrictions on gatherings. We are capping guests at 16 in these large properties as one step amongst several, all designed to mitigate any efforts to misuse an Airbnb for a party.”Airbnb says guests will be informed about its party rules and told that they may be “legally pursued” by the company if they violate the policy.Unauthorized parties have actually always been prohibited at Airbnb listings and the company says 73% of its listings already ban them in their house rules.Over the last year or two, Airbnb has begun imposing stricter limits, starting with a global ban on “party houses,” or listings that create persistent neighborhood nuisance. And when the COVID-19 pandemic hit, a new policy was introduced that required all users to adhere to local coronavirus mandates.“However, in many large jurisdictions, public health mandates on gatherings have changed – and in some places swung back and forth in response to the changing rates of COVID cases – as have regulations on bars, clubs and pubs,” wrote Airbnb. “Some have chosen to take bar and club behavior to homes, sometimes rented through our platform. We think such conduct is incredibly irresponsible – we do not want that type of business, and anyone engaged in or allowing that behavior does not belong on our platform.”Based on these developments, the company says instituting a global ban on parties and events is in the best interest of public health. 2265

SAN JOSE, Calif. (AP) — Fire investigators looking into what caused a wildfire that killed four people in far Northern California have taken possession of equipment belonging to Pacific Gas and Electric. PG&E says in a filing Friday with the Public Utilities Commission that investigators with the California Department of Forestry and Fire Protection seized some of its electrical equipment near where the Zogg Fire started Sept. 27. The fire erupted in Shasta County during high winds and quickly grew, killing four people in the community of Igo, population 600. It later spread to neighboring Tehama County. 623
