Cannabis Chemicals May Have Evolved to Deter Insect Pests
Cannabinoids may have evolved to deter pests from chewing on them, according to experiments that showed higher cannabinoid concentrations in hemp leaves led to proportionately less damage from insect larvae.
News
Inability of Macrophages To Penetrate Tumors Could Explain Cell Therapy Failures
Macrophages, a type of white blood cell that can destroy invading pathogens, have an innate ability to infiltrate tumor cells, making them a potentially important tool in treatments that use transplanted cells to fight disease, known as cell therapy.

A Personalized Approach Could Help To Tackle the Global AMR Crisis
Antimicrobial resistance (AMR) is threatening the effective treatment and prevention of a wide range of infections, with serious potential consequences for health and the economy. We spoke to Dr. Alaa Riezk, research associate at the Centre for Antimicrobial Optimisation (CAMO), Imperial College London, about the problem of usage and dosage of antimicrobials and AMR and how he and the team are working to address it.
