John Pregulman is on a mission to ensure that those who survived the Holocaust are not forgotten. Pregulman is occupied with documenting the estimated 200,000 still-living Holocaust survivors. “Their biggest fear is that they’ll be forgotten,” Pregulman said as he was surrounded by hundreds of portraits he took of survivors taped and pinned onto four walls.Among those Pregulman has documented was Mildred Ferro, 93, who said she was age 11 when she moved to the United States. Pregulman recently visited a senior living community to capture Ferro’s picture and story.Pregulman’s became motivated when he learned that many survivors worry that their story will be forgotten in history. What started as a one-time gig, taking photos at an event outside of Chicago five years ago, has turned into almost an obsession.“I took their pictures, they shared their stores, and I just became completely enthralled with these amazing people who I expected to be sad and unable to get past what had happened, and yet they were the happiest most positive and accomplished people I had met in a very long time,” he said.In hearing their stories, Pregulman and his wife soon learned a disturbing statistic: roughly one-in-three Holocaust survivors live in poverty.“Dignity had to be the centerpiece of everything,” his wife Amy Israel Pregulman said. “They deserve that.”They’ve started a non-profit called 1407

In regions of the United States and Mexico that are prone to hurricanes, aggressive spiders are evolving to survive and ride out the storm.When hurricanes rage along the Gulf of Mexico or charge up the East Coast, they can reshape an entire habitat in a short time. The winds destroy trees and spread debris for miles, putting new pressure on the creatures living in these environments.But how do creatures adapt when their habitats are so disturbed? Researchers looked at Anelosimus studiosus spiders that live in storm-prone areas along the coast to see how they changed. Their study was published Monday in the journal Nature Ecology and Evolution.These weather systems are called "black swan events": a surprising event with a major impact that is explained with the benefit of hindsight. They don't offer much lead time, so the researchers had to scramble to study the spider colonies before and after projected storms.The team monitored Subtropical Storm Alberto and Hurricanes Florence and Michael during the 2018 hurricane season. They tried to anticipate the systems' trajectories and study areas that included 240 female spider colonies, comparing them with areas where spider colonies were unaffected by such storms.The researchers returned to the sites hit by the storms 48 hours later. About 75% of the colonies survived the initial storm strikes."It is tremendously important to understand the environmental impacts of these 'black swan' weather events on evolution and natural selection," said Jonathan Pruitt, lead study author, evolutionary biologist and Canada 150 Chair in McMaster University's Department of Psychology, Neuroscience & Behaviour. "As sea levels rise, the incidence of tropical storms will only increase. Now more than ever we need to contend with what the ecological and evolutionary impacts of these storms will be for non-human animals."The A. studiosis spider species has two main personality traits that are inherited: docile and aggressive.Aggressiveness can be determined based on their speed, attackers pursuing prey, cannibalizing male spiders as well as eggs and their vulnerability to the invasion of predatory spiders.On the one hand, aggressive colonies are better at gathering resources in times of scarcity. But when deprived of food or subjected to overheating, aggressive colonies can also suffer from infighting."Tropical cyclones likely impact both of these stressors by altering the numbers of flying prey and increasing sun exposure from a more open canopy layer," Pruitt said. "Aggressiveness is passed down through generations in these colonies, from parent to daughter, and is a major factor in their survival and ability to reproduce."The researchers determined that after a storm passed, the colonies that aggressively pursued food and resources were able to produce more egg cases. The spiderlings also had a better chance of surviving into early winter.In areas that weren't hit by storms, docile colonies thrived.These findings were consistent even as the storms varied in duration, intensity and size. The researchers believe this shows that extreme events can shape animal behaviors. They would like to conduct more long-term studies to learn whether this is the case. 3250

Just when stores started filling their toilet paper shelves again, other items are suddenly in short supply. Most of them have nothing to do with cleaning.You'll recall that first it was hand sanitizer and Lysol wipes that became impossible to find back in February — which feels like it was three years ago in the time-dilated Twilight Zone of 2020.March arrived with face mask and toilet paper shortages, and cleaning sprays and products disappeared from store shelves.April brought the first shortages of beef, chicken and pork as processing plants shut down.As those items get restocked, other wells are running dry.Newer items that are getting hard to findBike shops across the country have been so busy during the pandemic that it's almost 758

  

Late last Saturday night, Ethan Crispo had just left a friend's birthday party in Birmingham, Alabama, and walked into a Waffle House around midnight to grab a bite.Crispo told CNN only a single employee was working in the restaurant.He described the cook's face, as "awash in bewilderment," at finding he was by himself managing the night shift.More than 30 people were there eating, and there was just one man left to "fend off the incoming crowd of hungry, heavily imbibed customers," Crispo said.He became resigned to going home on an empty stomach.But a customer finished his meal, asked for an apron and stepped behind the counter to wash dishes."It was a smooth transition," Crispo, 24, said. "He just busted his butt and helped out."'It was one of my most memorable experiences'Crispo said he asked Ben, the lone associate working, who the man washing dishes was.Turns out he didn't work at the restaurant, nor did he work at a Waffle House anywhere.Another woman, wearing a dress and heels, also stepped up. She walked behind the counter to get a coffee pot."At first I thought it was out of necessity, like she just wanted coffee," Crispo said. But she was enlisting as a second member of the volunteer staff.The two worked together in a team, busing tables, stacking cups and washing dishes. Meanwhile, Ben, the actual employee, manned the cash register and cooked at the grill.The man washing dishes occasionally "had to ask Ben where stuff should go," Crispo said, but otherwise it was as though though two strangers, without even talking to each other, had spontaneously learned to run a restaurant in tandem.Pat Warner, a spokesman for Waffle House, told CNN the store had a miscommunication about the duty roster that night, and it had created "a little gap" in staffing."We're very appreciative and thankful, but we do prefer to have our associates behind the counter," Warner said.He added that Waffle House restaurants tend to have a special sense of community. He recalled a similar time in 2014 when diners volunteered to keep a restaurant running when paid staff couldn't get to work during Atlanta's notorious Snowmageddon storm.But, for Crispo it was the first time, and it'll stick out to him for years to come, as an example of humanity at its best."I've never seen anything like this ever happen, nor will I again, probably," Crispo said. "It was one of my most memorable experiences." 2424

  

Inexcusable. My God. A police officer who tear gases a civilian whose hands are up does a dishonor to his colleagues and his city and needs to be brought to justice. https://t.co/zYvEKidJtQ— Corey Johnson (@CoreyinNYC) May 31, 2020 243
