Police say one person was fatally shot in Portland, Oregon, as Black Lives Matter protesters and people from a large caravan of President Donald Trump supporters clashed in the streets. It wasn’t clear if the shooting Saturday night was linked to fights that broke out as a caravan of about 600 vehicles was confronted by protesters in the city’s downtown. Police say the caravan had left the area about 15 minutes before gunshots rang out. Oregon’s largest city has been the site of nightly protests for three months since the police killing of George Floyd in Minneapolis. Trump referenced the city in a speech Thursday at the Republican National Convention. 668

Part of the cure for COVID-19 might be found in sharks dwelling deep in our oceans.“Everybody’s, ‘oh, there’s a hundred million being taken anyway, why are you worried about vaccine?’” said Stefanie Brendl of Shark Allies, a nonprofit for shark conservation.She says during the pandemic, more sharks are being harvested for squalene, an oil found in their livers and is often used to increase the effectiveness of vaccines.“The more products we come up with that require shark parts, the more we’re fueling this 100,000,000 sharks a year number,” she said.Brendl says many pharmaceutical companies are using shark squalene to produce a coronavirus vaccine and that if everyone in the world received two doses, 500,000 sharks would have to be slaughtered to meet the demand.“We need to look at this and we need to hold the vaccine companies accountable to test alternatives,” she said.One of the companies, Brendl, is calling out pharmaceutical giant GlaxoSmithKline, which plans on manufacturing 1 billion doses of a “pandemic vaccine” in 2021.While GSK says squalene pulled from shark livers is used in some of its vaccines, the company claims it’s also exploring squalene found in some plants.“One research team has tried to make in yeast so you could grow cultures of yeasts similar to fermenting beer,” said David Kroll, Ph.D., a professor of pharmacology at the University of Colorado, Anschutz Medical Campus.He says finding a cure for coronavirus will be the biggest vaccine undertaking in recent medical history.“The biggest concern is whether more sharks are going to have to be killed for this monumental global effort,” Kroll said.Shark experts believe this is a global challenge.“Many of the sharks that are being targeted are deep sea sharks and they’re found in open ocean environments that may not be protected,” said Chris Lowe, a professor of marine biology and director of the Shark Lab at California State University, Long Beach.He says tens of millions of sharks are already killed each year and some companies poach shark corpses for squalene to make numerous products ranging from vaccines to cosmetics.Lowe warns an increase in killings could impact our ecosystem.“Those animals play a very important role that could affect people on land,” he said.While the cost of a cure for COVID-19 is still unknown, Lowe says killing more sharks could mean extinction for several shark species. 2414

PHILADELPHIA, Pa. – Within a series of unfinished walls, Tom Stefanko oversees hundreds of construction workers every day, all of them wearing what looks like an old-school pager. Yet, the technology involved is new.“I think it gives workers a little bit of comfort,” Stefanko said.The devices are proximity tracers, designed to make sure workers on construction sites remain socially-distant during these pandemic times.“If I was in contact another person, it would start beeping red,” Stefanko said. “And if I stayed there longer, it progressively beeps louder.”While they alert workers that they’re too close to one another, the proximity tracers also record that data, in case a worker later ends up testing positive for COVID-19.“It provides the ability to have a real-time alerting system and then also be able to go back historically and see who's been in contact with whom to do the contact tracing,” said Robert Costantini, CEO of Triax Technologies.The company began to develop the proximity tracers when the coronavirus outbreak began.“The stakes are really high, if you get it wrong,” Costantini said. “I mean, workers could be infected. You can shut your site down. The cost can be enormous.”The contact tracers, though, cost about a dollar a day, per worker. More than 15,000 of them are now in use on more than 70 construction sites around the country, including the 1 million square foot building that Tom Stefanko and his team are working on in Philadelphia.“We have a thousand tags here on site,” Stefanko said. “Most workers just keep it on their hardhat. And take it with them as they come and go – so, making it as part of their PPE.”It’s personal protective equipment that is now a requirement to try and keep COVID-19 out of their workforce. 1772

Plans to build a new 4-acre, .5 million park in National City got a boost this week, thanks to a partnership with the federal government.The Environmental Health Coalition will help the city plan the park and the surrounding area, to make sure people can access the park without having to drive there.National City is one of just 10 communities across the country chosen for the Safe Routes to Parks Initiative.The new park will be near 22nd Street and Harding, where an empty field sits right now. As part of the construction, the EHC will help design safer streets around the park."Kids are trying to get from point a to point b and they have to cross through that main road," explains City Engineer Jose Lopez. "Without enhancements to the road, there's no way a 10-year old or 5-year old can cross the street."The EHC will help the city plan curb extensions, a median refuge island in crosswalks and local trails to let people walk through parks instead of along busy streets.According to a release announcing the partnership, communities chosen for the program had high rates of crime and violence, and also high rates of weight-related chronic diseases. The Safe Routes to Parks program  hopes to increase park use and help communities become healthier and safer.Right now the park is still in the planning stages. They hope to start construction in 2019. 1391
