A new study investigating the genetic makeup of dogs living near the Chornobyl Nuclear Power Plant compared to those in the nearby city found no evidence of radiation-induced mutations. Researchers analyzed the dogs' genomes for generations of accumulated changes but did not find any linked to radiation exposure.
The Chornobyl disaster in 1986 left a lasting impact on the surrounding environment. But a new study reveals a surprising finding about the dogs living in and around the exclusion zone.Researchers investigated whether decades of low-level radiation exposure had caused genetic mutations in dogs living at the Chornobyl Nuclear Power Plant compared to those in the nearby city of Chornobyl .
They were specifically searching for evidence of germline mutations, which are genetic changes that occur in reproductive cells and can be inherited by offspring.“We know that, for example, exposure to high doses of radiation can introduce instability from the chromosomal level on down. While this dog population is 30 or more generations removed from the one present during the 1986 disaster, mutations would likely still be detectable if they conferred a survival advantage to those original dogs.

Harmonizing Radiation Protection for Astronauts in SpaceExposure to radiation from the Sun and other cosmic sources poses a significant risk to astronauts, particularly during long-duration missions beyond Earth's protective environment. While different countries and space agencies assess this risk, a lack of harmonized guidelines hinders effective protection. A recent study published in the Journal of Medical Physics emphasizes the need for a consistent radiological protection framework for astronauts, addressing various challenges such as understanding the complexities of the mixed radiation field, accounting for sex and age differences in risk, and establishing acceptable levels of radiation-induced health effects.

Chornobyl NPP takes step towards safer future with radioactive waste management facilitiesThe State Nuclear Regulatory Inspectorate of Ukraine has approved the operation of new facilities at the Chornobyl nuclear power plant designed to process and store radioactive waste. The facilities, part of the EU-funded Industrial Complex for Solid Radioactive Waste Management (ICSRM), will handle various types of waste generated at the site, including waste from normal operation, decommissioning, and maintenance. This development marks a significant step towards long-term safety and environmental protection at the site of the world's worst nuclear disaster.

Houston Police Department Tackles Years-Long Evidence Storage IssueThe Houston Police Department, Harris County District Attorney's Office, and the city of Houston are collaborating to address a longstanding problem of evidence storage and processing. The issue came to light after a rodent infestation was discovered in the HPD's evidence property room, highlighting the buildup of 1.2 million pieces of evidence, with much of it deemed irrelevant. Officials plan to destroy narcotics from 2015 and prior, create a new liaison position to oversee evidence destruction, and move all current evidence to the Houston Forensic Science Center.
