E-cigarettes found to cause change in mouth bacteria – which could lead to gum disease or oral cancer

Bacterial changes could lead to serious diseases. vchal/ Shutterstock E-cigarettes are a popular alternative to smoking, but we still know very little about the effects of them on our health. While numerous studies have explored the effect of e-cigarettes on our lungs, heart, and overall health, one important and often overlooked consideration is what effect they have on our microbiome. But a recent study has found e-cigarettes change the bacteria in our mouths. These bacterial changes can lead to disease, if left unchecked.

The future of periods can now be sustainable and cheap

The coronavirus pandemic has triggered what has been described as a “sanitary pad crisis” in India. Priya, a 14-year-old schoolgirl, considers herself lucky: her parents can still afford pads. But several of her friends will have to go without. In some parts of India, schools are a critical part of the supply chain, providing a pack of pads to girls each month.

The hashtag was first used in November 2014, shortly after #BlackLivesMatter started trending. But since May 2020 #DalitLivesMatter had more engagement than the entirety of 2019 (engagement measured as the number of posts with 10 or more replies, likes and retweets).
