Chinese scientists have developed a new gene-editing tool called programmable chromosome engineering (PCE) that can precisely manipulate millions of DNA base pairs, overcoming a long-standing challenge and paving the way for advances in biomedicine, agriculture, and synthetic biology.
Researchers in Spain have discovered that blocking the enzyme topoisomerase I can halt the replication and spread of herpes simplex virus 1 (HSV-1) by preventing it from reshaping human DNA, opening potential pathways for a cure using existing cancer drugs, which could significantly impact the treatment of this widespread and incurable virus.
A former forensic scientist at the Colorado Bureau of Investigation manipulated or omitted DNA test results in hundreds of cases over her nearly 30-year career, prompting a full review of her work. The internal investigation found that Yvonne “Missy” Woods' handling of DNA testing data affected 652 cases between 2008 and 2023, leading to a separate criminal investigation and a federal lawsuit alleging wrongful conviction. The agency is conducting a comprehensive audit of all DNA analysts to ensure the accuracy and completeness of its records, and a separate case of potential data manipulation by an analyst at the Weld County Sheriff’s Office has been discovered.
