The Environmental Protection Agency announced a commitment to fully eliminate animal testing by 2035."This is a longstanding personal belief on my behalf," EPA Administrator Andrew Wheeler said Tuesday, recalling an op-ed he wrote for his college newspaper, The Observer, at Case Western Reserve University, in 1987, which the agency handed out to reporters.The EPA has relied on animal testing to evaluate the risks of chemicals and pesticides to human health but has taken steps in recent years to move toward new alternatives and technologies. The Toxic Substances Control Act that was amended in 2016 to reduce reliance on animal testing as well.Animal rights groups, including the Humane Society and PETA, praised the move."PETA is celebrating the EPA's decision to protect animals certainly, but also humans and the environment, by switching from cruel and scientifically flawed animal tests in favor of modern, non-animal testing methods," said Dr. Amy Clippinger, director of PETA's regulatory testing department.Wheeler said the agency will provide .25 million in grant funding to five universities, Johns Hopkins University, Vanderbilt University, Vanderbilt University Medical Center, Oregon State University and University of California Riverside, to research alternative test methods, like computer modeling and invitro testing.However environmental groups slammed the EPA's directive, raising concerns about the adequacy of the alternative test methods for all chemicals, and arguing the move largely benefits chemical companies more than the public."EPA is eliminating tools that lay the groundwork for protecting the public from dangers like chlorpyrifos, formaldehyde and PFAS. Phasing out foundational scientific testing methods can make it much harder to identify toxic chemicals -- and protect human health," Jennifer Sass, senior scientist for the Healthy People and Thriving Communities program at the Natural Resources Defense Council, said in a statement. 1993

The earth hasn't stopped rumbling under Southern California since Thursday, when a powerful 6.4-magnitude earthquake rattled Ridgecrest and the surrounding area.The quake was followed by more than 1,400 aftershocks, according to scientists. On Friday, an even stronger quake -- with a magnitude of 7.1 --- rattled the region, leaving residents traumatized, Ridgecrest Mayor Peggy Breeden said Saturday morning."Many of them are sleeping outside tonight," Breeden said. "They're fearful to be in their homes. Many are choosing to just be with their neighbors ... in their sidewalks, in their driveways and some of them are in the streets."There's been an average of one aftershock per minute since Friday's quake in the southern part of the state, according to the 776

The Centers for Disease Control (CDC) says depression affects nearly 8% of people at any time. The numbers of those who get treatment are far lower. For some, they don’t recognize the symptoms or they don’t want to take medication. Wendy Moreno is among those who struggle with depression. After a traumatic experience four year ago, she decided she needed professional help. She went to therapy and got on medication, but she didn’t feel it was working.“I was just at a point where I wanted to try something new,” said Moreno. Her therapist told her about 569

The CDC has recently issued guidance indicating that up to nearly one half of antibody tests are inaccurate.While early indications are that having antibodies offers some protection against reinfection, the CDC said too little is known about antibodies to determine whether it is safe for a person to no longer need to conduct social distancing. Additionally, the CDC said that a positive test should not be used at this time to determine if an individual is immune.The CDC added, “Serologic test results should not be used to make decisions about grouping persons residing in or being admitted to congregate settings, such as schools, dormitories, or correctional facilities.”The CDC said that it recommends providers use multiple antibody tests on patients, and it obtains the most accurate tests available.The CDC said that the prevalence of those testing positive for antibodies among the general population is between 5 and 25, with higher figures coming from areas with localized outbreaks. The FDA has also warned that all antibody tests can produce false results, and that “broad use of the tests, when not appropriately informed by other relevant information, such as clinical history or diagnostic test results, could identify too many false-positive individuals.” 1286
