President Donald Trump tweeted on Monday that Sec. of Defense Mark Esper has been terminated.Trump added that he has tasked Christopher C. Miller to take over as Acting Sec. of Defense.Esper took over as Acting Sec. of Defense in June and was named as the department's director shortly thereafter. Late last week, NBC News reported that Esper had drafted a resignation letter in the days following the 2020 presidential election.Esper has been at odds with Trump throughout his tenure. In June, he said he opposed the President's call to use active-duty military members to break up protests against police brutality in the wake of George Floyd's death.NBC News also reports that Esper plans to help Congress draft legislation that would re-name military bases that honor Confederate generals — a policy that Trump also opposes.Esper was Trump's second full-time Secretary of Defense. Jim Mattis served in the role from 2017 until Jan. 1, 2019, when he resigned following Trump's call to remove U.S. troops from Syria. 1026

Protests broke out in Atlanta early Saturday, hours after at least one Atlanta Police officer shot and killed Rayshard Brooks, 27, outside a Wendy’s late Friday.In the wake of Friday's shooting, Atlanta Mayor Keisha Lance Bottoms announced the resignation of Police Chief Erika Shields. "It has become abundantly clear that over the last couple weeks in Atlanta is that while we have a police force full of men and women who work alongside our communities with honor respect and dignity," Bottoms said, "there has been a disconnect with what our expectations are, and should be as it relates to interactions with our officers and the communities in which they are entrusted to protect."Body worn or dash cam video of the incident was released to the public late Saturday. Video circulating on social media reportedly of the incident shows a man grabbing a stun gun from police during a struggle and running from officers. The video shows officers then shooting Brooks as he tried to flee.“The (Georgia Bureau of Investigations) is aware that there is video posted on social media captured by witnesses in this incident. We are reviewing the video & the early investigative information in this case. We’ll provide an update as soon as we can,” the agency said Saturday morning.The Georgia Bureau of Investigations said that officers responded to a call of a man who fell asleep behind the wheel in a drive thru. The police accused Brooks of failing a field sobriety test.Police then claimed Brooks struggled with officers during the arrest. The Georgia Bureau of Investigations said that officers then fired a Taser at Brooks.Eyewitnesses told investigators that Brooks then struggled with officers over the Taser, and that’s when at least one officer shot Brooks.Brooks was transported to the hospital, and he died during surgery.Atlanta has been the site of a number of large protests in recent weeks in the wake of the death of George Floyd. Floyd died on Memorial Day in police custody after a Minneapolis police officer held a knee against his neck for nearly nine minutes.The NAACP reacted to Saturday's shooting via Twitter. "Stop urging the black community to be patient as our people are being gunned down by those sworn to 'protect and serve.' Sweeping police reform is no longer a consideration," the NAACP said in a statement. 2349

Researchers have determined there are five kinds of cat owners, when it comes to their feelings about their felines roaming and hunting outside.Outdoor cats can be a danger to birds, rodents and small reptiles, and also create dangers for themselves from disease, larger predators and traffic.Researchers at the University of Exeter in the United Kingdom are trying to bring awareness to the downsides of cat outdoor roaming and the impact on wildlife, and published part of their ongoing study. They note that several attempts have been made to address the issues, including reducing the cat population, regulating ownership and restricting feline outdoor access.“Such proposals rarely account for cat owners’ perspectives, however, and are frequently met with strong, principled opposition,” the study’s authors wrote.They found cat owners fell into five “types”:Concerned Protectors focus on cat safety. They are most worried about their pet’s safety outside and would feel guilty if the cat died while roaming. They are likely to keep their cats inside most of the time if not permanently.Freedom Defenders prioritize cat independence and natural instincts, “like a wild animal,” and oppose restrictions on behavior. They believe keeping cats inside is cruel, and that any of the risks of being outside are outweighed by the benefits. They generally are not bothered by their cat’s hunting and some expressed pride in their pet’s hunting abilities.Tolerant Guardians believe outdoor access is important for cats but dislike their hunting and are more likely to bring their cat inside at night. Generally, this group of cat owners try to rescue prey captured by their cats, accepting that their pet is a “carnivorous wild creature” while saving all wildlife.Conscientious Caretakers feel some responsibility for managing their cats’ hunting. They are worried about their cat’s roaming, and the impact on birds and other smaller creatures. This group generally believes cats require outdoor access, but are not opposed to confinement. They are open to hunting-control measures that owners can take.Laissez‐faire Landlords were largely unaware of the issues surrounding roaming and hunting behavior. This group generally is concerned their pet may be stolen, get killed in traffic or get lost if outside roaming. They also have never thought about the effect their cat has on wildlife outside. They also believe belled collars are an effective way to manage their cat’s hunting.The large majority of study participants also felt that cats should be allowed outside at least some of the time. The study’s authors note that four of the five groups viewed hunting to be negative and may be open to more information about how to limit their pet’s predation.They recommend policymakers stay away from “blanket restrictions” and instead work with cat owners on strategies. “Identifying, refining, and promoting viable management tools and alternatives may be a more constructive approach to resolving this issue than regulation,” the study concludes. 3053

Researches in the United Kingdom have found a purr-fect way for you to communicate with your cat.A recent study published in the online journal Scientific Reports found that cats will appear friendlier and more approachable to humans who use slow-blinking, eye-narrowing facial expressions, which psychologists at the Universities of Portsmouth and Sussex referred to as a "cat smile."In their first experiment, 21 cats interacted with their owners. The psychologists' team found that the cats would slow-blink if their owners slow-blinked at them first, compared to a neutral expression.In its second experiment, 24 cats and a member of the research team interacted. The study found that if the experimenter slow-blinked at them first, they were more likely to approach their outstretched hand than if they had given the cat a neutral expression."Collectively, our results suggest that slow blink sequences may function as a form of positive emotional communication between cats and humans," the researchers said. 1022
