Across the country, officials are re-evaluating policing methods after the death of George Floyd put police brutality in the spotlight. Now, schools are weighing in, too.Fueled by the rise in school shootings in the last decade, hundreds of high schools and middle schools have hired armed police officers, also known as school resource officers, to patrol campuses.But just as civil rights groups like Black Lives Matter are calling for a change in policing, the Gwinnett Parent Coalition to Dismantle the School to Prison Pipeline (GwinnettSToPP) is calling for a change in school security."We've been at this for quite some time. We've done a lot of things along the way to mitigate the effects of police in schools," said Marlyn Tillman, the co-founder of GwinnettSToPP.Since it was established 10 years ago, the group has aimed to remove police officers from school campuses. Tillman says that when police are on campus, what used to result in a trip to the principal's office now means a "trip in handcuffs.""Most of them have two guns, a taser and a baton. They definitely all have one (gun) and then they are allowed to carry their own personal firearm," Tillman said. "That image is not the image that garners safety. That is an image of violence."Denver Public Schools (DPS) recently joined several other large school districts across the country in removing school resource officers from campuses — but the change isn't immediate. DPS currently plans to eliminate school resource officers by the end of the 2020-2021 school year."There are other ways to think about safety, and this is the time to do that," said Denver school board member Jennifer Bacon.Bacon believes there is a way to keep schools safe without projecting the image of violence that comes with an armed officer."There are things we will always have to call police officers for," Bacon said. "We cannot handle guns. We cannot handle controlled substances. But having them present suggests that a kid is 'that close' to doing a crime."Fresno High School student Richard Romero believes students will feel safer without officers patrolling on campus, but he doesn't think they should be eliminated. He feels a single resource officer could handle duties for multiple schools."Some altercations don't always need police. They just need relations to be restored," Romero said.DPS and other school districts hope that without resource officers on campus, educators can take a restorative justice approach to discipline — focusing on education and child development instead of punishment."A restorative process is an opportunity for them to learn from it. Giving someone a ticket, you know 27-year-olds can learn that way, but not a 10-year-old," Bacon said. 2739

ALBANY, N.Y. (AP) — The man who killed John Lennon in 1980 says he was seeking glory and deserved the death penalty for a "despicable" act. Mark David Chapman made the comments last month to a parole board before it denied him parole for an 11th time. The now 65-year-old inmate expressed remorse for gunning down the former Beatle. Chapman called his actions "creepy" and "despicable." He said he thinks all the time about the pain he inflicted on Lennon's wife, Yoko Ono. The board said it found his statement that "infamy brings you glory" disturbing. Chapman will be up for parole again in August 2022. 614

A years-long battle between the Cornwall-Lebanon, Pennsylvania School District and social studies teacher Luke "Todd" Scipioni finally came to an end this week when a court ruled that Scipioni can return to work, the Lebanon Daily News reported. School officials learned in 2014 that Scipioni had sex with a female student on her graduation night in 2004. The allegations surfaced during Scipioni's divorce proceedings, the Daily News reported. The Daily News reported that Scipioni and the student developed a relationship during the 2003-04 school year, but it did not turn sexual until student's graduation. The relationship ceased when she went off to college at the end of the summer. The district then fired Scipioni in October 2014 when it confirmed the relationship between Scipioni and the student. Scipioni then challenged the district in court, with an arbitrator’s ruling that Scipioni was not forthcoming in the details of the relationship, and that he should be suspended for one year, but not banned from teaching. This week, the Pennsylvania Supreme Court ruled that Scipioni should not have been punished beyond the suspension, and is entitled to return to his job.Scipioni is reportedly interested in returning to work for the district after he and the district settle on back pay. A district spokesperson said that while it disagrees with the ruling, it will abide by the justices' ruling. 1546

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
