African American Community Leaders Speak Against Legalizing Hallucinogens in California

African American Community Leaders Speak Against Legalizing Hallucinogens in California African American community leaders in California held a press conference on July 8 to voice opposition to a bill that would legalize hallucinogenic drugs in the state. Senator Scott Wiener (D-Calif.) has stated that Senate Bill 519 is meant to address the war on drugs and to help veterans better access these drugs to manage their mental health needs. “Let’s be clear that there’s another reason, and that is … the racist war on drugs, which has fueled mass incarceration and torn apart communities, particularly communities of color, but not made us any safer,” Wiener said during a press conference on June 28.

New DNA-based technique allows researchers to determine age of living beluga whales in Alaska

New DNA-based technique allows researchers to determine age of living beluga whales in Alaska Researchers can now determine the age and sex of living beluga whales in Alaska’s Cook Inlet thanks to a new DNA-based technique that uses information from small samples of skin tissue. Accurate age estimates are vital to conservation efforts for Cook Inlet belugas, which were listed as endangered following a significant population decline in the 1990s. Previously, researchers could only determine the age of beluga whales by studying the teeth of dead animals. The new aging method uses DNA methylation data and machine learning to develop a model that captures the relationship between methylation and age. This relationship provides an epigenetic clock for beluga whales.
