A non-profit in California has developed a way to capture poachers who snatch sea turtle eggs - building lookalike eggs with GPS trackers constructed inside them.According to research published Monday in the journal Current Biology, the InvestEGGator is a 3D-printed life-like turtle egg that can be tracked as far away as 137 kilometers (85 miles)."It replicates the appearance, weight, and feel of a real turtle egg. It is easily deployed at low risk to investigators, can be programmed and monitored remotely using web-based and smartphone applications, and is a low cost, allowing for deployment of many units at once," the company said on its website.The decoy eggs are placed in real nests alongside real eggs, which are monitored and mapped every time they are moved, said the Ventura-based Paso Pacífico, the non-profit that developed the eggs.The research showed that the decoy eggs provide a signal once every hour."Using data provided by the decoys, we identified trafficking routes and on two occasions properties of potential interest to law enforcement," researchers said in the journal. "Decoys also yielded anecdotal information, furthering our understanding of trafficking routes." 1206

A new warning Tuesday cautions toxic chemicals were discovered in several popular back-to-school items. Everything from crayons and markers, to binders and water bottles.The U.S. Public Interest Research (USPIRG) groups tested 27 school supplies and found that some of them contained toxic chemicals like asbestos, lead, benzine and phthalates, which have been linked to cancer and other health hazards.“You can't assume that things are automatically safe when they're on our store shelves,” says Danny Katz, with USPIRG.Katz's team found Playskool crayon from Dollar Tree had trace amounts of asbestos. But that wasn't it.A blue jot band binder from Dollar Tree tested positive for phthalates.  Additionally, dry erase markers from Amazon tested positive for benzine, even though the packaging says nontoxic.“Just because a product says nontoxic like that, doesn't mean it's been tested for all the different chemicals,” Katz explains.Katz says what you should look for is a symbol, which confirms the product has been tested and approved by the Consumer Product Safety Commission.His team has put together a list for parents and teachers of products that tested positive for toxic chemicals and those that didn't.“There's just no reason that these chemicals need to be in the school supplies,” Katz says. “There's plenty of school supplies that don't have them. So we're shining a spotlight on which ones have these toxic chemicals which ones we didn't find in helping teachers and parents to stay safe.”  1535

A new US government report delivers a dire warning about climate change and its devastating impacts, saying the economy could lose hundreds of billions of dollars by the end of the century.The federally mandated study was supposed to come out in December but was released by the Trump administration on Friday, at a time when many Americans are on a long holiday weekend, distracted by family and shopping.David Easterling, director of the Technical Support Unit at the NOAA National Centers for Environmental Information, emphasized that there was "no external interference in the report's development." He added that the climate change the Earth is experiencing is unlike any other."The global average temperature is much higher and is rising more rapidly than anything modern civilization has experienced, and this warming trend can only be explained by human activities," Easterling said.Coming from the US Global Change Research Program, a team of 13 federal agencies, the Fourth National Climate Assessment was put together with the help of 1,000 people, including 300 leading scientists, roughly half from outside the government.It's the second of two volumes. The first, released in November 2017, concluded that there is "no convincing alternative explanation" for the changing climate other than "human activities, especially emissions of greenhouse gases."The report's findings run counter to President Donald Trump's consistent message that climate change is a hoax. On Wednesday, Trump tweeted, "Whatever happened to Global Warming?" as some Americans faced the coldest Thanksgiving in over a century.But the science explained in these and other federal government reports is clear: Climate change is not disproved by the extreme weather of one day or a week; it's demonstrated by long-term trends. Humans are living with the warmest temperatures in modern history. Even if the best-case scenario were to happen and greenhouse gas emissions were to drop to nothing, the world is on track to warm 1.1 degrees Fahrenheit.As of now, not a single G20 country is meeting climate targets, research shows.Without significant reductions in greenhouse emissions, the annual average global temperature could increase 9 degrees Fahrenheit (5 Celsius) or more by the end of this century, compared with preindustrial temperatures, the report says. 2355

A new health hazard is washing up on shores around the world.“They found a lot of it in Italy. They found a lot of PPE in beaches of Japan and Southeast Asia,” said senior scientist Jennifer Brandon, Ph.D. about personal protective equipment, or PPE. “We’re already finding thousands of gloves and masks as the pandemic continues.” Brandon believes more people are using and also improperly disposing of these single-use plastics and says the litter can last several lifetimes.“I would not be shocked if it’s going to be in the hundreds of thousands in gloves and masks in the next years,” she said.Brandon says with grocery stores no longer allowing reusable bags and restaurants serving to-go orders in Styrofoam containers, this is adding to the problem.This swell of plastic pollution has a chain effect, impacting animals and humans.“That plastic is going to get eaten by animals and those animals are what you eat,” Brandon said. “Sometimes it can break down small enough, it even gets into our water supply and sea salts.”Experts say 30 billion pounds of disposable plastic is dumped into the ocean every year. Now, that number is expected to rise even more due to PPE waste.“We expect that plastic pollution will outweigh fish in the ocean if we don’t take care quick action to prevent that from happening,” said Shelley Luce, president of Heal the Bay, a nonprofit with the mission of keeping water clear and clean.“We do beach clean ups year-round and we generally get 700 to 800 people coming out early on a Saturday morning,” she said.With social distancing orders and many beaches closed due to COVID-19, large group gatherings are no longer allowed in some areas.So, Luce is now encouraging people to clean up what she calls “COVID waste” on their own or within their social bubble.“You can do a cleanup in your neighborhood,” she said. “Pick that trash up off the streets because you know where that's going to go, into a storm drain and out into the ocean.”Luce says there are simple solutions for this worldwide problem: properly dispose of PPE or wear a cloth mask, both of which can help stop the spread of coronavirus without creating an environmental hazard. 2187

A Miami police officer has been relieved of duty after a video showed him kicking a suspect in the head, as the man was lying on the ground and getting handcuffed."The video depicts a clear violation of policy," Miami Police Chief Jorge R. Colina said in a statement. "The officer has been relieved of duty and the Miami-Dade State Attorney's office has been contacted."A cell phone video shot by a witness shows a man lying in a yard with his hands on his head. The first police officer approaches him and starts putting handcuffs on the suspect. The suspect, identified as David Suazo in the police report, was not resisting and was lying on his stomach. His hands are being restrained. Suddenly, another officer can be seen running toward him and kicking him in the head.That officer then drops to the ground next to the suspect and appears to put him in a headlock.A woman can be heard expressing shock. "You didn't have to do all that, buddy. You tripping."CNN has attempted to reach the officer, Mario Figueroa, but has not yet gotten a response. A call to the Fraternal Order of Police was not returned. 1118
