After the death of George Floyd, cries to defund the police in Minneapolis assumed center stage. But one non-profit there has been working for years to abolish the department: MPD 150.“We didn’t think this moment would be here this soon,” said Peter Vankoughnett, a member of the group.MPD 150 was formed several years ago, and the members took a look at the history of the Minneapolis Police Department, its influence on the community and efforts at reform since the department started more than 150 years ago.Vankoughnett said the goal of the group has been and still remains, “to change the narrative around policing from reform minded to abolitionist minded.”In the group’s performance review, moments in history, like the 1934 Teamsters Strike where officers opened fire on unarmed strikers, killing two people and injuring 67, and the civil unrest in the streets in 1967 were referenced as points where the department overstepped in their interactions with the community.“There’s never been a point in the police department where there hasn’t been large amounts of race and class based violence,” said Vankoughnett.Their findings also document the department’s influence on the community and its lack of oversight. Since 1963, five separate oversight committees have formed to monitor ethics within the department, only to be dissolved. The non-profit reports few committees have seen more than 10 percent of all complaints result in disciplinary action for officers.“From the beginning, the committees were designed where they don’t have real power, they can only make recommendations, or they’re stacked with police officials,” said Vankoughnett.Seeing the past and living through today’s unrest, MPD 150 began losing faith in reform and planning for a police-free future.“Not that everyone here is in favor of it, but now, everybody has to talk about it,” said Vankoughnett.That conversation was catapulted into the mainstream by the death of George Floyd, and as the Minneapolis Police Department’s third precinct was set on fire by protestors, calling for change, the Minneapolis City Council listened, pledging to dismantle the department.So, how can we live in a world where police aren’t on the streets? MPD 150 says there’s a way to make that happen, starting with prevention.Vankoughnett said that means diverting money from the police to community resources.“It’s about underlying causes,” he said. “A lot of violence might come from unemployment—it’s happening right now you can see it in this city. So putting money into employment, into drug treatment are all principles of abolition,” Vankoughnett said.It also means diverting 911 calls to the right responder, not having zero responders. “We’re not trying to make it so there’s nobody to call, we’re trying to figure out who you can actually call that will do a better job than the police department would do,” said Vankoughnett.The Minneapolis Police Chief, Medaria Arrandondo, said in a press conference he has no plan to leave this city without a fight for reform first—even with the issues the department has faced.He outlined several reforms including using new technology to monitor officers in real time, hoping to catch disciplinary issues before dangerous situations ensue.Holding just as tightly to a new vision for the future: the community this department serves. A police-free city may take years, but Vankoughnett believes it will come.“I hope we’re able to able to look back at these few years as a revolution in history. That we’re able to step away from these old models of policing, and I think this could be the place where that happens,” said Vankoughnett.If you’d like to know more about MPD 150’s performance review, click HERE.For other alternatives to policing as it currently stands, here is a LIST of MPD 150’s detailed ideas to move forward. 3848

According to a recent paper, the Earth is caught directly in the crosshairs of a cosmic hurricane.A swarm of nearly 100 stars, accompanied by an even greater amount of dark matter, is aimed directly at our stellar neighborhood and there's nothing we can do to stop it; in fact, the vanguard is already upon us. This sounds like a perfect summer blockbuster movie, starring The Rock and Chris Pratt, or maybe Scarlett Johansson and Charlize Theron.Except this is for real. But is it a danger? Well, actually, no. Not at all. But it's potentially incredibly fascinating, with lots of interesting scientific interconnections. So, what is really going on?The story starts last April, when the Gaia satellite announced the locations and trajectories of 2 billion stars in the vicinity of the Milky Way surrounding our sun. They released the data to the public.Scientists were then able to look at the data set to see if they could spot anything peculiar. In galaxies like the Milky Way, the most common behavior is that the stars orbit the center of the galaxy in a manner broadly similar to the planets orbiting our sun. However, there are some stars that exhibit unusual motion. About a year ago, astronomers identified some "stellar streams" passing through our celestial neighborhood.One of them, called S1 (for stream 1), consists of nearly 100 stars of similar age and composition, orbiting the Milky Way in a direction exactly opposite that of normal stars. It's kind of like a handful of cars driving the wrong way down the highway, except with a much greater distance between them and with no likelihood of a collision. These stars are spread out over a few thousand light years and they will pass through the solar system's neighborhood over the course of a few million years.Astronomers identified S1 as being part of the remnants of a dwarf galaxy that collided with the Milky Way and was consumed in an epic episode of cosmic cannibalism. Dwarf galaxies are very small, typically about 1% the mass of the Milky Way. They can orbit larger galaxies and collide with the bigger galaxy, adding their mass to the parent. This is what appears to have happened in the case of S1, although the process has taken probably a billion years.Dwarf galaxies often have a disproportionately large fraction of dark matter. Dark matter is a hypothetical and still-undiscovered form of matter that interacts only gravitationally. Scientists have proposed its existence to explain many astronomical mysteries, for example the observation that most galaxies rotate faster than can be explained by the known laws of physics and the stars and gas of which they are composed.While dark matter has not yet been observed, hypothesizing its existence is the simplest and most economical explanation for myriad astronomical mysteries. Averaged over the entire universe, dark matter is thought to be five times more prevalent than the ordinary mass of stars and gas and planets.In dwarf galaxies, the fraction of dark matter is often higher. In Fornax, a well-studied dwarf galaxy orbiting the Milky Way, researchers estimate that the dark matter is between 10 and 100 times greater than the mass found in its stars.If that number holds for S1, the dark matter of the S1 stream is passing through the Earth at a much higher velocity than the more ordinary dark matter that orbits the Milky Way -- about twice as fast. It is thought that S1 dark matter is flying through the solar system at a speed of about 550 km/s, or about 1.2 million mph. While these numbers are impressive, they are misleading. Dark matter, if it exists, is extremely diffuse and it will have no discernible effect on the solar system.Because dark matter hasn't been observed yet, these velocity numbers are speculative, although they are strongly supported by a very large body of evidence. However, the prospect of high velocity dark matter flying through the Earth has suggested an opportunity to detect it.In a paper in the prestigious journal Physical Review D, researcher Ciaran O'Hare and his collaborators calculated the possibilities of discovering dark matter using both existing and proposed dark matter detectors. They considered two varieties of dark matter particles: a very heavy kind called a WIMP (weakly interacting massive particle) and a very light kind called an axion. Because the ultimate nature of dark matter is not known, it is important to be open to all possibilities.They found that the detectors they evaluated could find WIMPs for certain ranges of the particle mass. However, when they looked at the axion possibility, it appeared the prospects were even better. Because of its light mass and the manner in which an axion would interact with the detector, the apparatus simply has a better chance of seeing the axion. (If axions exist, of course.)Experiments with names like ADMX, MADMAX and ABRACADABRA are able or will be able to search for the signatures of dark matter proposed in the recent paper. They consist of technologies that are designed to interact with axions in a strong magnetic field and convert them to ordinary microwaves or radio waves that can be easily detected.It's important to remember that the S1 stream poses no credible threat to the Earth and humanity. There is no need for an action hero to save us. However, the synergy of science is staggering. A careful catalog of nearby stars has opened the prospect of a better possibility of finding and identifying dark matter, which is one of the great unanswered mysteries of modern physics. It's an amazing time we live in, in which we can study such things.\ 5625

About 1 million people in the U.S. are confirmed to have contracted COVID-19 in the last five days, according to a database kept by Johns Hopkins University.As of Tuesday afternoon, 15 million Americans have contracted COVID-19 since the disease arrived in the country in January. The U.S. surpassed the 14 million case threshold on Thursday.According to USA Today, one out of every 22 Americans has contracted the virus.Even with the virus spreading to about 200,000 new Americans every day, top health officials expect the spread to only increase further in the coming days. Even with the current spike in cases, infectious disease expert Dr. Anthony Fauci says the country still is not yet seeing the full brunt of what is expected to be an exponential spread of the virus that was prompted by Thanksgiving travel.More people traveled by airplane during the week of Thanksgiving than at any other time during the pandemic, and officials believe the increase in travel and indoor gatherings will cause a "spike superimposed upon a spike" of virus cases.The spread also comes amid a concerning crowding of hospitals across the country. According to the COVID Tracking Project, a record 102,000 people in the U.S. are currently hospitalized with the virus, putting many hospitals and health care facilities at capacity. Some hospitals have been forced to treat patients in temporary facilities in parking garages because they have run out of beds. The frightening spike and concerning lack of space comes amid the deadliest week of the pandemic yet. The U.S. has reported an average of 2,200 COVID-19 deaths each day for the last week — a number that officials suspect will only increase as the virus continues to spread. Officials are holding Americans heed public health measures for the next few weeks, as two COVID-19 vaccines appear poised for imminent approval. On Tuesday, the UK began distributing its first initial doses of a two-shot Pfizer COVID-19 vaccine — the first Western country to begin distributing vaccinations. 2045

  

ALABASTER, Ala. — A photographer in Alabama was able to capture the beauty of a rare yellow cardinal that is taking the internet by storm. Jeremy Black took the photograph of the rare yellow bird in Alabaster, Alabama.According to Geoffrey Hill, a bird curator at Auburn University in Alabama, the bird is a rare male northern cardinal that has a "one in a million" genetic mutation that makes its red feathers turn yellow. Additionally, the mutation is so rare, that only one is seen each year in the United States."This yellow cardinal displays a rare mutation causes the metabolic process to produce a different type of pigment than the typical red coloration," Black wrote on his Facebook page.Black says that he was able to photograph the yellow cardinal after his friend, Charlie Stephenson, noticed the bird at her feeder in January. According to National Geographic, on February 17, Black spent five hours in Stephenson's backyard with a camera in hand, hoping the beautiful bird would make a second appearance. "As soon as it landed, I was starstruck," Black told National Geographic. "It kind of took my breath away a little bit."Black's next goal is to capture a picture of a yellow cardinal and a red cardinal sitting on a branch together.Mary Stringini is a Digital Reporter for ABC Action News.

Access to city and county beaches will be limited for the Fourth of July weekend because of the statewide and local spike in COVID-19 cases.An order banning vehicular access to Nueces County bay and gulf beaches goes into effect Friday morning at 6 a.m. and ends at 6 a.m. July 7.The restrictions also include golf carts and all-terrain vehicles.What the order does not address is where the thousands of beach visitors expected this holiday weekend will be able to park.With beaches limited to pedestrians only, parking places will be at a premium because once they’re gone, you’re going to have to walk.Just a few weeks ago, local officials expected thousands of tourists flocking to Padre Island and packed beaches, similar to what we saw Memorial Day weekend.“You could have driven that beach and you weren’t going to find a space to get in on the beach,” said Director of Coastal Parks Scott Cross.Nueces County tried a similar plan over Easter weekend, with mixed results.“Easter weekend when we closed it down, it proved to us that the honor system is not going to work with these cables and barricades,” said Cross.This weekend, the county will keep vehicles out by blocking access roads with giant sand berms. While public parking near the beach is limited, local leaders aren’t worried.“We don’t expect traffic volumes to be where we thought they would be about two weeks ago,” said Corpus Christi City Manager Peter Zanoni.Even though Corpus Christi is a tourist destination, Zanoni believes now is not the time for out-of-town visitors.“We have a crisis going on here in our county; we’re one of the fastest-growing areas in terms of new COVID cases every day,” said Zanoni.City and county leaders worked closely to get beach orders out as early as possible to give potential visitors plenty of notice.“Hopefully people will hear the warnings, hear the advice,” said Zanoni. “If they do make it here it’s going to be a tough walk from anywhere on the island to the beach, I’m not sure that will be in their best interests.”“It’s really important that we do this for the safety of the people living here and the safety of people visiting here,” added Cross.KRIS' Greg Chandler first reported this story. 2221
