More than 100 law enforcement agencies have withdrawn from helping the Milwaukee Police Department at the Democratic National Convention, three weeks before the big event. According to the police chief, the agencies cited concerns over potential new policies related to crowd control.The Milwaukee Police Department requested the help of more than 1,000 officers from other law enforcement departments for security at the Democratic National Convention. Even though the event will be scaled-down at the Wisconsin Center due to the COVID-19 pandemic, losing many of these officers will make things more complex for Milwaukee police.Chief Alfonso Morales now has to deal with a new task with only three weeks until the DNC.He could not reveal the number of officers he’s lost for security reasons but says the reason agencies pulled out of the convention has to do with the Fire and Police Commission directives given to him last week related to crowd control. Specifically, they’re concerned over the directive to discontinue the use of tear gas and large amounts of pepper spray.“When you rule an unlawful assembly to help break up that crowd, once we deem them unruly, that’s a safe manner in doing so. Not having those tools increases the potential for more violence,” Morales said. “That’s a big concern for the law enforcement community within Milwaukee and outside of Milwaukee.”This is how the departments in West Allis, Fond du Lac and Franklin feel. They’re just three of the local agencies that withdrew. Altogether, they were going to send 30 officers.here does the police department go from here? Morales said he’s concerned if they’ll have enough law enforcement to protect Milwaukee and visitors at the DNC. He doesn’t reject getting help from the National Guard or federal government.“Those will be options and those options are still at the table,” Morales said. 1885

NASA's OSIRIS-REx mission and the asteroid Bennu have had a date planned for two years, and just after noon ET today, they finally got to meet face to face. OSIRIS-REx fired its thrusters for a small burn, putting it about 4.3 miles from Bennu, marking the end of its journey to the asteroid.The mission -- which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- is NASA's first asteroid sample return mission. It launched in September 2016 and will spend two years up close and personal with Bennu. First images of the asteroid from the spacecraft's perspective have appeared as it got closer and closer.On Tuesday, the spacecraft will fly within 5 miles of Bennu, which will help design future orbits and map the surface.Over the next year, OSIRIS-REx will survey the asteroid using five scientific instruments on board the spacecraft. These instruments will help it determine a safe location from which to collect a small sample from Bennu's surface that will be returned to Earth in September 2023."Bennu's low gravity provides a unique challenge for the mission," said Rich Burns, OSIRIS-REx project manager at NASA's Goddard Space Flight Center. "At roughly 0.3 mile in diameter, Bennu will be the smallest object that any spacecraft has ever orbited."The sample from Bennu, a near-Earth asteroid, could help scientists understand not only more about asteroids that could impact Earth but about how planets formed and life began.OSIRIS-REx has a camera suite, a laser altimeter for 3D mapping, a thermal emission spectrometer to take temperature and mineral content and spectrometers to measure X-rays, nearly infrared and visible light.An arm mechanism called TAGSAM will reach out to collect the sample from Bennu's surface, making contact with the asteroid for five seconds in July 2020. During this contact, the arm will use a nitrogen gas burst to stir up rock and other materials on the surface so it can capture them. There is enough nitrogen for three attempts if the first is unsuccessful.NASA said the estimated 2.1-ounce sample size equates to about 30 sugar packets worth of dirt and rocks.The arm has a full range of motion, with joints capable of movement comparable to shoulder, elbow and wrist joints. It was "flexed" in space for the first time on November 14."The TAGSAM exercise is an important milestone, as the prime objective of the OSIRIS-REx mission is to return a sample of Bennu to Earth," said Dante Lauretta, OSIRIS-REx principal investigator at the University of Arizona, Tucson. "This successful test shows that, when the time comes, TAGSAM is ready to reach out and tag the asteroid."In 2021, it will be time for the spacecraft to essentially turn around and begin its two-year journey home. The sample will be packed into a capsule that will drop in the Utah desert in 2023.For two years after the return, the sample will be cataloged and analyzed. Afterward, 75% of the returned sample will remain at NASA's Johnson Space Flight Center so it can be used for more research by scientists from around the world.Why did NASA select Bennu out of the 780,000 known asteroids in our solar system?It was discovered in 1999, and scientists have been studying it ever since. The asteroid fits a number of criteria that make it intriguing and convenient.Bennu is relatively close to Earth, and its orbit even crosses that of our planet, making a close approach every six years. Though small asteroids can rotate very quickly, Bennu has a diameter just a bit bigger than the height of the Empire State Building and rotates relatively slowly, each 4.3 hours. This means OSIRIS-REx can match its velocity and touch down briefly.The asteroid could pass close to Earth, closer than the moon, in 2135, with even closer approaches possible in 2175 and 2195. A direct hit is unlikely, but the data gathered during this mission can help determine the best ways to deflect near-Earth asteroids.The asteroid is also old and well-preserved, full of valuable materials that may even contain clues about how life began. Bennu is essentially a leftover from the formation of our solar system billions of years ago, although some of the minerals inside it could be even older.This carbon-rich asteroid could be full of organic molecules, metals, platinum and even water -- the essential ingredients for life. It's because of objects like Bennu that these resources were delivered to Earth during its formation.Asteroids could even serve as fuel stations for robotic and human missions if we can unlock the hydrogen and oxygen inside them, NASA said.Bennu probably broke off of a larger asteroid in the asteroid belt between Mars and Jupiter a couple billion years ago. This knocked it through space until an orbit close to Earth locked it in place. And Bennu is believed to be a grouping of rocks held together by gravity rather than a single object.But its orbit drifts 0.18 miles each year toward the sun, and OSIRIS-REx will enable researchers to understand why and to predict Bennu's movements. This could also explain how it ended up as a near-Earth asteroid."The story of this asteroid is the story of the solar system," said Bashar Rizk, instrument scientist for OSIRIS-REx. "When we understand Bennu, we will understand something fundamental about our solar system."The-CNN-Wire 5356

MSAN DIEGO (KGTV) -- Mayor Kevin Faulconer announced Monday that the city has repaired 655 miles of roads so far, which is ahead of schedule to meet the goal of 1,000 miles of roads by 2020.Averaging more than 300 miles per year puts the city ahead of schedule, even as a small percentage of repairs has required taking the roads down to the dirt.RELATED: San Diego County approves million road resurfacing project“The unprecedented investment we’ve made in road repair is showing results with more smooth streets in our neighborhoods,” Mayor Faulconer said. “There’s still a lot more work that needs to be done, but we’re making significant progress on an issue that is a top concern for so many residents.”Within the first two fiscal years of the pledge, the city fixed 595 miles of roads. Last year, an assessment showed the overall condition of city streets rose to 72 on a scale of zero to 100.RELATED: Mayor vows to fix more roads in San DiegoMayor Faulconer says if they do complete the work ahead of schedule they will assess additional roads and keep going.Click here to report potholes and road issues.

NASHVILLE, Tenn. — Vanderbilt University Medical Center (VUMC) says it performed the world's first dual heart-lung transplant of a COVID-19 patient in September.The hospital says the patient, described as a young man, had cardiomyopathy — a disease of the heart tissue that can lead to heart failure — before he contracted COVID-19 in June.The procedure, which was completed on Sept. 24, was also VUMC's first heart-lung transplant since 2006. Dr. Ashish Shah performed the complex surgery, along with Dr. Matthew Bacchetta.Shah said the patient's battle with COVID-19 seriously damaged his lungs and may have also further damaged his heart. By September, the patient was critically ill with advanced heart and lung disease. He was referred to VUMC from the University of Mississippi Medical Center."He was slipping fast, in and out of the hospital and certainly by the time we operated on him, his heart was really done," Shah said.Bacchetta and Shah performed the transplant using both lungs and the heart from the same donor, which the hospital says is standard in dual transplants. VUMC says the organs were from a donor who had hepatitis C, and that the hospital is one of the first centers to use such organs for patients awaiting heart and lung transplants.They say the patient has since left intensive care and continues to recover at the medical center, where he is doing well.According to VUMC, a dual heart-lung transplantation is rarely performed in the U.S. and typically only done at high-volume transplant centers, like Vanderbilt."This transplant, like every transplant we perform, serves as a great example of the critical role of teamwork in leading to good outcomes," said Dr. Kelly Schlendorf, the medical director of VUMC's Adult Heart Transplant Program. "It really does take a village.""It continues to lead the way in pioneering this strategy, which has significantly increased the supply of donor organs," VUMC said Friday in a release.This story was originally published by Laken Bowles on WTVF in Nashville, Tennessee. 2053
