A new peer-reviewed study from the Environmental Working Group finds that advanced PFAS filtration systems not only remove toxic "forever chemicals" from drinking water but also significantly reduce other harmful contaminants. These include cancer-linked disinfection byproducts, agricultural nitrates, and heavy metals like arsenic and uranium. The study, published in ACS ES&T Water, analyzed data from 19 U.S. utilities and the EPA’s national monitoring program, showing that technologies like granular activated carbon, ion exchange, and reverse osmosis offer broader public health benefits than previously recognized.

When detached cancer cells squeeze through the tiniest blood vessels they can become prone to grow new tumours far from where they started, a blood flow simulation experiment suggests.

New research shows that colorectal cancer is unique in having its own microbial ‘fingerprint’. Colorectal cancer is the fourth most common cancer in the UK and the second deadliest. The research could help doctors better understand how this cancer develops, how aggressive it might be, and even how a patient might respond to treatment. The team studied whole genome sequencing (WGS) data from more than 9,000 cancer patients.  The analysis also challenges scientific claims that all cancers are associated with a unique microbial fingerprint
