The Cost of Freeing Drinking Water from ‘Forever Chemicals’

In proposing the limits, EPA officials said that they had leveraged the latest science to protect the public from PFAS pollution. Environmental groups welcomed the move as long overdue. But the standard has drawn widespread criticism from the water utility industry and some scientists who say that in many places, small drops in PFAS water levels will matter little for exposure or health.

Radiation therapy takes advantage of cancer’s poor DNA repair abilities – an oncologist and physicist explain how

Nearly half of all cancer patients undergo radiation therapy as part of their care. Ionizing radiation, or the emission of high-energy waves or particles, works as a therapy by damaging a cancer cell’s DNA. It’s an effective tool for killing cancer cells because they are generally much less adept at DNA repair compared to healthy cells. Damaging specific parts of DNA prevents cancer cells from reproducing, effectively killing them.

What happens to your liver when you quit alcohol

Most people who regularly drink more than the recommended limit of 14 units of alcohol per week (about six pints of normal strength beer [4% ABV] or about six average [175ml] glasses of wine [14% ABV]) will have a fatty liver. Long-term and heavy alcohol use increases the risk of developing scarring and cirrhosis.
