A new invasive tick is spreading through the United States, which is the first time in 50 years a new species has come to the country.The Asian long-horned tick has spread throughout the Eastern Seaboard already, causing mild concern from public health experts, according to The New York Times.The new arrival has yet to be found carrying any human diseases here. Domestic American ticks carry pathogens and transmit them into people rather often."In Asia, however, the species carries a virus that kills 15 percent of its victims," according to the Times.The new ticks are considered a threat to livestock.According to the Times, the long-horned ticks “can multiply rapidly and suck so much blood from a young animal that it dies. The ticks bloat up like fat raisins until their tiny legs are barely able to support them.”So far, the tick has been found in seven states. Experts say the tick is hard to identify."It is an aggressive biter and frequently builds intense infestations on animals causing great stress … and blood loss," according to a statement sent to The Charlotte Observer from the North Carolina Department of Agriculture“Even experts have difficulty distinguishing among tick species, so it is important to take precautions to protect pets, livestock and family members from becoming a host for ticks of any kind,” state veterinarian David Wolfgang told the Pocono Record. “Scientists don’t yet know how this species will adapt to the North American climate and animal hosts, but we know it survived New Jersey’s winter and has infested sheep and cattle in this region.”So far, the tick has been found in Arkansas, Pennsylvania, New York, Virginia and West Virginia.The tick can survive throughout the year, according to the York Daily Record.“We know it can survive very harsh winters. It can handle those winters in other countries, and we know it has survived winters in New Jersey as well,” said Shannon Powers, spokeswoman for the Pennsylvania Department of Agriculture.Dr. Rachel Levine, Pennsylvania's secretary of health, told the Pocono Record people should be cautious when outside.“Ticks can be found in your own backyard, so it is essential to wear long sleeves and pants, use insect repellent containing DEET to help keep you safe from ticks and the diseases they carry. It is also important to check yourself and your pets for ticks, as pets can bring ticks indoors.” 2413

A viral video showing security camera footage taken in Chula Vista, California on Halloween night may help restore your faith in the honor system. Kim Manalo's family joined the throngs of trick-or-treaters racing door-to-door in their neighborhood.  Manalo wanted to keep the spirit of Halloween alive at her home while they were out, so she left a bowl filled with candy outside their door with a note asking people to help themselves.  Her hope was that people would leave a treat for the next candy-seeker."We came home to an empty bowl and hoped there weren't greedy kids that didn't leave some behind for others," Manalo wrote on her post.She studied security footage to see if perhaps someone grabbed more than their share of goodies. What Manalo found on her security camera video was a surprise that almost made her cry."Instead we found this clip of a wonderful soul who shared some candy from his own bag to keep the halloween spirit going for other kids," Manalo she wrote.The video shows one of the boys reach into his bag and place some of his own candy in the bowl for the next trick-or-treaters. “He didn't even know the camera was there,” Manalo said. “None of his friends knew and to take that second out of his time from his own stuff just really warmed my heart.”San Diego-based KGTV posted the surveillance video on Facebook after Manalo's friend shared the footage with reporter Joe Little.  The video has garnered hundreds of reactions, shares, and comments."If only all of us raised our children to be so thoughtful even when no one is seemingly looking. He will change the world someday if he keeps it up," wrote Jeremy Ellis.The identity of the thoughtful boy remains a mystery, but numerous adoring Facebook fans are looking for clues to thank him for inspiring the spirit of community. 1941

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 meteor shower that occurs annually due to Earth passing through dust released by Halley's Comet is set to peak Tuesday and Wednesday.According to AccuWeather, observers should expect to see up to 20 meteors per hour when the Orionid meteor shower peaks.Space.com says between 1 to 5:45 a.m. local time is the best time to watch the meteor shower.According to the Weather Channel, it's best to avoid light pollution (if possible) and not use binoculars or telescopes if you want to view the shower. 507

A new boarding process is coming to Delta Air Lines.Beginning on January 23, 2019, the airline will ditch zone boarding in favor of a new — and more complex — process based on ticket type and color.Despite the expansion in number of groups from six to eight, Delta said the new format hopes to "encourage fewer customers to line up in the gate area" and ultimately speed up boarding.The Atlanta-based carrier will still begin boarding with passengers that need extra time, followed by premium passengers sitting in its Delta One suites (applicable on select domestic and all international flights) and then its new Premium Select cabin on some international flights or First Class on domestic flights.After that, it gets complicated: The airline used to board the Sky Priority zone — passengers sitting in Comfort+ and Gold and Platinum Medallion members — together.Moving forward, that group will split into two, with Comfort+ passengers boarding first followed by Sky Priority, meaning high-spending members of its frequent flier program will have to wait a little bit longer.Following that, Delta will board economy passengers by announcing Main Cabin 1 though 3, instead of Zone 1 though 4.Fliers that purchase Delta's cheapest tickets will board last in a new group: Zone 4 will now be called Basic Economy. Delta credit card holders and Silver Medallion members will board with Main Cabin 1.Each section will have different colors displayed when they purchase their ticket on Delta's website and on airport screens to help."This latest enhancement further refines how Delta's process works and is designed to better link the Delta product they purchased to differentiated experiences throughout their journey," said Tim Mapes, Delta's chief marketing officer, in a statement.Delta (DAL) joins United (UAL) and American (AAL), which both recently revamped their boarding processes. The goal is to minimize delays and load planes quicker. 1950
