ROMULUS, Mich. — Romulus police seized hundreds of exotics animals from an illegal collection on Thursday.According to police, it was a tip from a concerned citizen that led them to investigate.In the collection were 300 hedgehogs, six Flemish giant rabbits, three large iguanas, two kangaroos, a peacock, silver fox and a 16-foot reticulated python.Police say they have identified the person they believe was keeping the animals, and they are looking to speak with him.They did turn over all of the animals to people who could properly take care of them. 568

Sports gambling giant DraftKings is reviewing a former "Bachelor” contestant's million win in an online fantasy football contest after she and her husband are accused of cheating. Jade Roper-Tolbert beat more than 100,000 entries to take the top prize in DraftKings' "Millionaire Maker" contest this past weekend. But some complained she'd colluded with her husband, Tanner Tolbert, who is a prolific fantasy sports player and fellow “Bachelor” alum. The couple submitted 300 entries into the contest, nearly all of them listing a unique lineup of players from the NFL’s four wild-card games. 607

Summer is in full swing, and with the warmer months comes the mosquitoes. Not only are the small insects pesky, they are considered the deadliest animal in the world, believe it or not. More than 700 million people around the globe get sick from mosquito bites, and more than 700,000 people die from those bites each year."We always see West Nile Virus peaks right after the Fourth of July weekend, because people have been outside and not protecting themselves," says Kylee Grenis, an expert on mosquitoes. Grenis helped us conduct an experiment to find out which bug repellent works the best.We purchased three mosquito traps. We sprayed one trap with DEET. The other with a top rated non-DEET spray called Skin So Soft by Avon. The third trap was a controlled trap with no spray.The traps were hung next to dry ice in a mosquito-infested park."We are going to hang some dry ice near those traps to simulate a human standing and breathing and hopefully that will help attract more mosquitoes to our traps," explains Grenis on the use of dry ice. After an hour, the trap sprayed with DEET had one mosquito. In the Avon-sprayed trap, there were no mosquitos. In the control trap, there were six mosquitos. The sprays kept the mosquitos away.As far as sprays go, Grenis says she still prefers DEET. "It is great at making you invisible to mosquitoes,” she says. “That blocks the receptors so that they can't detect your carbon dioxide signature." But, many consumers fear products with DEET are not safe. "I think a lot of the time people get it confused with DDT,” she explains of Dichlorodiphenyltrichloroethane (DDT), a chemical compound banned in many countries due to the danger it poses to wildlife and the environment.DEET is safe to use and just like the Avon spray, and both sprays are effective in keeping mosquitos away during the summer time months. 1872

SpaceX launched 60 more mini internet satellites late Monday, this time testing a dark coating to appease stargazers.It’s a “first step” compromise between SpaceX and astronomers fearful of having dark skies spoiled by hundreds and, eventually, thousands of bright satellites circling overhead.The Falcon 9 rocket blasted into a cold, clear night sky, recycled by SpaceX for its fourth flight. As the first-stage booster flew to a vertical landing on an ocean platform, the Starlink satellites continued hurtling toward orbit to join 120 similar spacecraft launched last year. Flight controllers applauded, and the launch commentator described the booster’s fourth touchdown as “awesome.” An hour later, all 60 satellites were free of their upper stage and making their own way in orbit. “It’s a beautiful sight,” the commentator observed.His Starlink fleet now numbering 180, SpaceX founder and chief executive Elon Musk plans to ultimately launch thousands of these compact flat-panel satellites to provide global internet service. Each spacecraft is just 575 pounds (260 kilograms).After the first Starlink batch of 60 was launched in May and the second in November, astronomers complained how the bright satellite chain was hampering their observations. In response, SpaceX came up with a darkening treatment to lessen reflectivity. The coating is being tested on one of the newly launched satellites.Jeff Hall, director of the Lowell Observatory in Flagstaff, Arizona, said the Starlinks have been just an occasional problem — so far — but noted the risk to stargazing will grow as the constellation expands and other companies launch their own fleets. He heads the American Astronomical Society’s committee on light pollution, space debris, and radio interference, and is working with SpaceX on the issue. The matter is on the agenda, in fact, at the society’s conference in Hawaii this week.“Anything that darkens the satellites is a step in the right direction,” Hall said in an email Monday. He said it’s too soon to know whether the dark coating will work, “but it definitely is just a first step and not enough to mitigate the issues astronomy will experience with the Starlinks.”The Starlinks are initially placed in a relatively low orbit of 180 miles (290 kilometeters), easily visible as a long, strung-out cluster parading through the night sky. Over a few months, krypton-powered thrusters raise the satellites to a 340-mile (550-kilometer) orbit. The higher the orbit, the less visible the satellites are from the ground, according to SpaceX. Even so, SpaceX said it’s supplying astronomy groups with the satellite coordinates in advance, so they can avoid the bright flyover times.Already established in launching satellites for others and making space station deliveries for NASA, SpaceX is among several companies looking to provide high-speed, reliable internet service around the world, especially in places where it’s hard to get or too expensive. Others include Jeff Bezos’ Amazon and OneWeb. SpaceX may start service later this year in the northern U.S. and Canada, then expand to the world’s most populated areas after 24 launches. 3170
