At first glance, you would never know that Rich Mahoney’s clothes are different. That’s until, of course, you hear the hum of tiny robotic machinery working beneath the surface.That’s because underneath Mahoney’s clothing is what he calls robotic clothing.“It’s like a layer of extra muscles integrated into your clothing around your body,” he says.Mahoney is the 376

BAR HARBOR, Maine - Towns spotted along the coast in Maine are commonly known for two things -- lobster and whale watching. But scientists have noticed changing climate patterns over the past decade, and it’s causing changing patterns with different sea life.“The Gulf of Maine has historically been known as an important place for whales,” Allied Whale Marine Director Sean Todd said. “That has sort of changed because of climate, and the Gulf of Maine is slowly shifting in a way that is perhaps less attractive to the whales.”“What’s really emerged in the last decade or so is that this ecosystem is going through some really dramatic changes,” Dr. Andrew Pershing with the Gulf of Maine Research Institute said.Bar Harbor, Maine, is a town filled with restaurants and shops, A lot of what you see caters to tourists who frequent the town in the summer months.“Bar Harbor is a really fun town,” Zack Klyver, a former whale watch tour guide with over 30 years of experience, said. “It is full of magnificent life.”“I like to think of it as the place all the hippies went when they grew up,” Todd said.Fall marks the end of the tourism season, and many places close up shop for the winter.“A vast majority of jobs in bar harbor are due to the tourist industry,” Jeff Dobbs, a local documentary filmmaker and operator of the Acadia Channel.“If you come to Bar Harbor, there are three things you can do,” Todd said. “The first thing is you can visit Acadia National Park.” Todd goes on to explain the other two things you can do are eat lobster or go on a whale watch.“We carry about 50,000 to 60,000 people whale watching each summer,” Zack Klyver said. He works in part with Bar Harbor Whale Watch Company.The people are super excited when they see whales,” he said. “In recent years things have changed and we’ve had to go a lot farther to see whales.”Three-hour tours have become five-hour tours, to allow extra time to travel farther to find where the whales are. Klyver said they had a record July this year with the number of passengers they saw, but it was in part due to good weather conditions.“Our sightings have gone down in the last couple years,” Klyver explained.While whale watch trips look for all types of whales, these were the stats Klyver shared with Finback whale sightings:2000 - 160 trips with at least one Finback whale sighting2010 - 155 trips with at least one Finback whale sighting2017 - 5 trips with at least one Finback whale sightingThose numbers have since improved.“In past years we looked at our sighting success rate and we were often at 80 to 90 percent success in seeing whales,” Klyver said.“This was a very difficult year for us. It’s getting hard to study these animals because they’re just not around,” Todd said. “It used to be that whales were very predictable here in the Gulf of Maine.”Todd explained he thinks the ocean is warming to a point it’s no longer an attractive place for whales to come and they are making other choices in terms of looking for food.One of the species choosing to stay north is the endangered North Atlantic Right Whale.“The Right Whale population was recently estimated in 2017 at being about 411,” Klyver said. There are less than 100 viable, breeding females left.Meanwhile, Todd said the Gulf is seeing more warm water species, including more Mola Mola sunfish.“The Gulf of Maine is one of the most rapidly warming patches of saltwater anywhere on the planet,” Todd said.Doctor Andrew Pershing agrees -- and had the science to back it up.“Over the last 30 years or so, we have warmed at a rate that’s about four times the global ocean average,” Doctor Pershing said. “Really since about 2010 this ecosystem has been going through a remarkable transformation where every year it seems to get warmer and warmer.”He said all areas of the ocean are warming by .01 degrees Celsius a year, on average.“We’re losing some of our subarctic species that have really been the center of the food web at the Gulf of Maine,” he said. “The whales are having to adjust on the fly to figure that out, and that makes it harder for the companies that have set up shop in a particular area with the expectation they can go offshore and quickly find the whales.”“What’s happening with climate may be kind of abstract,” Zack Klyver explained. “A fire in California, or a melting glacier somewhere that they hear about but for us it’s real. We’re seeing it everyday on the ocean.”And just like the season, the Gulf of Maine is changing.“A lot of people plan their vacations completely around seeing whales, they’ll come from all over the world,” Klyver said.Klyver and Jeff Dobbs are working on a documentary about the Right Whale, in hopes of bringing more attention to the endangered animal.“The plight of the Right Whale hasn’t gotten any better,” Dobbs said. “Their status in the world is very important, people don’t realize how much they contribute to the global economy.”Fishing and shipping are two things that are detrimental to the whales, according to Todd. “I am deeply motivated to save these animals. Deeply motivated,” he said.“We really have to rethink how we make decisions about natural resources how we make decisions about our businesses, we really have to look towards our future,” Doctor Pershing said. 5289

At first, teachers at Sky Valley Education Center simply evacuated students and used fans to clear the air when the fluorescent lights caught fire or smoked with noxious fumes. When black oil dripped onto desks and floors, they caught leaks with a bucket and duct-taped oil-stained carpets.Then came the tests that confirmed their suspicions about the light ballasts.“Sure enough ... it was PCB oil,” said Cynthia Yost, who was among teachers who sent pieces of carpet and classroom air filters to a lab. Tests found elevated levels of the toxic chemicals, used as coolant in the decades-old ballasts that regulated electrical current to the lamps.Millions of fluorescent light ballasts containing PCBs probably remain in schools and day care centers across the U.S. four decades after the chemicals were banned over concerns that they could cause cancer and other illnesses. Many older buildings also have caulk, ceiling tiles, floor adhesives and paint made with PCBs, which sometimes have been found at levels far higher than allowed by law.Yet the Environmental Protection Agency has not attempted to determine the scope of PCB contamination or assess potential health risks, in large part because of lack of funding, political pressure and pushback from industry and education groups, according to dozens of interviews and thousands of pages of documents examined by The Associated Press.Members of Congress who promised three years ago to find money to help address PCBs and other environmental problems in the nation’s schools never introduced legislation.And an EPA rule that would have required schools and day cares to remove PCB-containing ballasts moved slowly under the Obama administration, then was quashed by President Donald Trump within days of his inauguration.That was the final straw for Tom Simons, a former EPA regulator who worked for years on the rule and said getting rid of ballasts was the least the EPA could do to protect children.“We thought it was a no-brainer: There are millions out there. These things are smoking and dripping, so let’s put this through,” said Simons, who retired shortly after Trump took office.___For decades, the presence of PCBs in schools flew under the radar.States, cities and environmental agencies focused on removing them from lakes, rivers and toxic waste sites because most exposure to PCBs is believed to come from people’s diet, including fish from contaminated waterways, and because PCBs do not break down easily. Studies have linked them to increased long-term risk of cancer, immune and reproductive system impairment and learning problems.PCBs, or polychlorinated biphenyls, are mixtures of compounds manufactured by Monsanto Co. and widely used as coolants and lubricants in electrical equipment until they were banned in 1979.By then they were in transformers, air conditioners, adhesives, carbonless copy paper and billions of fluorescent light ballasts in schools, hospitals, homes, offices and commercial and industrial buildings. They also were ubiquitous in the environment and building up in human bodies.Nobody worried about schools.Then a 2004 study by Harvard health professor Robert Herrick identified the widespread use of PCBs as a plasticizer in caulk in schools built before 1980, estimating that as many as 14 million students and 26,000 schools could be affected. The EPA had not been aware of its use in caulk before then, Simons said.The EPA later found that the chemicals can move from building materials into the air and dust, where they can be inhaled or ingested. They also can be absorbed by walls and other surfaces as an ongoing source of exposure.Regulators also discovered that old fluorescent light ballasts remained a potentially widespread source of PCB contamination. The EPA had allowed the ballasts to remain in use because chemicals were in enclosed capacitors that experts thought would last only about 12 years. But it turns out they can last a half century or longer, said Simons.The older they are, the more likely ballasts will leak, catch fire or smoke. And that has happened repeatedly in schools, office buildings, restaurants and factories in recent years, according to reports reviewed by the AP.But the EPA has mostly voluntary guidelines, including recommended indoor air limits for PCBs that it says should protect children from health problems.The agency does not require — or encourage — schools to test for PCBs, so few do. If they are found in materials such as caulk, schools could be forced to undertake expensive cleanups when many are struggling to keep basic infrastructure intact and meet educational needs. Drawing attention to the issue also risks alarming parents.PCBs are illegal in building materials in concentrations exceeding 50 parts per million — a threshold set by the EPA decades ago based on how much contaminated material could affordably be removed rather than health risks.Rather than fostering “a very confusing and fearful situation,” the EPA should recommend that schools test classroom air for PCBs, then identify and address specific sources if the results are elevated, said Keri Hornbuckle, a civil and environmental engineering professor at the University of Iowa and one of the nation’s top researchers of PCBs in schools.“There is a good reason PCBs were banned, so ... let’s remove the worst cases and where (kids) are most vulnerable and have the highest exposure,” she said. “But you have to have the data.”Whether PCBs are addressed often is determined by ZIP code.In California’s wealthy Santa Monica-Malibu School District, parents, including model Cindy Crawford, sued to force the district to address PCBs after tests of caulk found levels up to 11,000 times the 50 ppm threshold. The district ultimately agreed to get rid of PCBs. It has torn down a middle school and continues to remove them from other buildings.In Hartford, Connecticut, the ending was far different. John C. Clark Elementary and Middle School, in a largely low-income African American neighborhood, was permanently closed in 2015 after PCBs were found and the city could not afford to remove them. The city has sued Monsanto and a company that manufactured caulk to recover the costs.“It was the crown jewel of the neighborhood,” Steven Harris, a former city council member and grandfather, said as he walked the deserted school grounds. “Our school board is doing the best they can. The reality is we don’t have a lot of money. And it’s going to take money to fix this problem.”Monsanto, now owned by Bayer Crop Sciences, has denied responsibility in lawsuits involving several school districts, saying it did not manufacture the building materials or components that contained PCBs.Concerns over schools like Hartford’s are one of the issues that ultimately kept the EPA from taking stronger steps to address PCBs.The agency, which originally recommended that schools test for the chemicals, was warned by the Association of California School Administrators that forcing schools to remove PCBs could create “a civil rights issue” if low-income minority schools could not afford it. What’s more, many of those schools have other environmental problems — including lead, asbestos and mold — that could be higher priorities.So instead, the EPA developed guidance that promotes vigilant cleaning and better ventilation and suggests schools could cover materials suspected of containing PCBs until the buildings are renovated or razed.But the recommendations were released quietly on the agency website to avoid publicity that might frighten the public, according to former EPA officials who said the agency was hamstrung by a problem that could cost billions of dollars. There are no rules requiring school officials to tell parents if they find or suspect their buildings have PCBs.Judith Enck, administrator of the EPA’s Region 2 under Obama, said the EPA bowed to intense political pressure.“The debate was never based on science and health. It was ‘We don’t want the grief from schools, and it’s a lot of work and we have other priorities,’” said Enck, who led an effort to get ballasts out of New York City schools. “I disagreed.”A bill introduced in 2010 by three New York congressmen aimed at funding school PCB cleanups was withdrawn after New York City officials agreed to replace aging ballasts.

Baltimore did not take President Donald Trump's recent attack of the city lying down. Instead, Charm City was quick to stand up and fight back.Trump lashed out at another prominent African American lawmaker on Saturday, tweeting that his Baltimore district is a "disgusting, rat and rodent infested mess."The President's tirade was directed at House Oversight Committee Chairman Elijah Cummings, who represents Maryland's 7th Congressional District in the House and recently lambasted conditions at the border. Trump's attack against Cummings was the latest verbal assault against a minority member of Congress who is a frequent critic of the President.The President suggested that conditions in Cummings' district, which is majority black and includes parts of Baltimore, are "FAR WORSE and more dangerous" than those at the US-Mexico border and called it a "very dangerous & filthy place."Cummings, the city's leaders and residents were quick to defend Baltimore. The Twitter hashtag #wearebaltimore was trending Saturday night, with users posting pictures and comments expressing their pride in the city."Mr. President, I go home to my district daily," Cummings wrote on Twitter Saturday in response. "Each morning, I wake up, and I go and fight for my neighbors. It is my constitutional duty to conduct oversight of the Executive Branch. But, it is my moral duty to fight for my constituents."Baltimore's Mayor Jack Young also took the attack to heart, criticizing Trump for disparaging a "vibrant American City.""It's completely unacceptable for the political leader of our country to denigrate a vibrant American City like Baltimore, and to viciously attack U.S. Representative Elijah Cummings a patriot and a hero," Young tweeted.The Baltimore Sun's 1773

At Dayton Consolidated School in Maine, one student has inspired a big change to the curriculum. Morey Belanger, a 6-year-old kindergartener, is the school's first deaf student. To make her feel welcome, the school embraced the opportunity to teach all the students some sign language.Sign language posters now line the walls of hallways, and students have learned how to sign more than 20 words including colors, letters and words related to school."Morey -- without even knowing it -- has taught us so much," said school Principal Kimberly Sampietro. "She has brought a culture to our building that we didn't have before."The school installed a hearing assistive system and implemented extra teacher training to incorporate sign language into every classroom, including core subjects, music and computer class. Sampietro said many teachers also began using their free time to watch sign language videos and read books on special education.The kindergarten class is also getting some help from Morey."Morey helped all of them to learn the alphabet," Sampietro said. "The kids have just really embraced her. They look up to her, they want her around, and they want to partner with her."Morey's mom, Shannon Belanger, said her family has been blown away by how supportive the school has been."I absolutely feel like it makes her feel welcomed," Belanger said. "I think all the kids feel excited that they know another language and I think they think it's fun."To celebrate the students' hard work, the school invited a real-life princess who knows sign language to come speak to students this week."We wanted to show our students that this isn't something they can only speak with Morey," said Principal Sampietro, who said most students in their rural Maine school have not encountered many people with hearing impairment. "We wanted to show them that signing happens in all kinds of settings."Morey's mom said she loves art and performing. So when Cinderella came to sing to the entire elementary, she helped with the singing and the signing, of course. 2067
