Horseshoe crabs are prehistoric creatures that predate the dinosaurs, but pharmaceutical companies depend on them to this day for their unique blue blood.The crabs’ blood is hypersensitive to endotoxins, making it the perfect testing ground to see if a coronavirus vaccine is harmful to people."The fact that we rely so much on these really primitive creatures that predate the dinosaurs," said Barbara Brummer, the state director of The Nature Conservancy in New Jersey.From Massachusetts to South Carolina, the crabs are collected and taken to laboratories. But one of their largest breeding grounds is right in New Jersey, in the Delaware Bay."The concern is the population of horseshoe crabs in the Delaware Bay has been declining over the years," said Brummer. "They are needed for the ecological value they bring for shorebirds.”Shorebirds rely on the crabs' millions of eggs for food.New Jersey fishermen are banned from using the crabs for bait. But pharmaceutical companies remove about a half-million horseshoe crabs from the ocean every year.In the labs, about one-third of a crab's blood is removed for testing. If the crab's blue blood clots up, the medicine is no good.The crabs are then returned to the ocean.However, a study by the Atlantic States Marine Fisheries Commission estimates about 15% of the crabs do not survive."There is an alternative test," Brummer said. "They have created a test that does not involve the bleeding of the crabs. It is a synthetic material."The synthetic test has been approved in Europe but has not yet been approved in the United States.This story was first reported by Christie Duffy at PIX11 in New York, New York. 1674

Hate crimes across the U.S. have risen to the highest level in more than a decade. And federal officials have recorded the highest number of hate-motivated killings since the FBI began collecting that data in the early 1990s. An FBI report released Monday shows there were 51 hate crime murders in 2019. That includes 22 people who were killed in a shooting that targeted Mexicans at a Walmart in the border city of El Paso, Texas, in August 2019. There were 7,314 hate crimes last year, up from 7,120 the year before. Advocates want the federal government to mandate police agencies report hate crimes to the FBI. The current system is voluntary. 655

Harmless Halloween decor or something more?Residents in a Phoenix neighborhood say they were alarmed to see their neighbor's display featuring four bloodied sheets hanging from a tree with nooses around the necks.One woman said she's offended by the decorations and feels they are extremely inappropriate."My most generous assessment is that it is a defiant, very racist act to make people feel unwelcome in this community, and it's heartbreaking," neighbor Amanda Gilmore said.Phoenix-based KNXV spoke to the homeowner, who said the decorations were simply up for a Halloween party and he did not anticipate the reactions from his neighbors. He took down the display after hearing the objections. 720
