Marijuana Use Affects Your DNA
Despite a growing number of states legalizing marijuana, we're still learning about its effects on our health. A recent study suggests cannabis use changes our epigenome. Those are chemical changes to the bases that make up DNA, that mark the genome in a way that tells it what, where, and when to do something. Each cell has unique epigenetic marks that are not inherent to DNA but can be passed from cell to cell, and one generation to the next.

A Vaccine for Lung Cancer
Despite a drop in smoking, the number of new lung cancer cases continues to climb. It's among the more deadly cancers with more Americans dying from it than any other cancer. Fortunately, a new vaccine to treat lung cancer is being tested. There are two main types of lung cancer, non-small cell and small cell.

Biomolecules are Left or Right Handed
Just like us, our biomedical world is either left or right-handed. For example, proteins, the machines of our cells are left-handed molecules. A DNA helix is right-handed which means the helix twists to the right. Other right-handed molecules in our cells are sugars such as glucose.

Preventing AMR from Surpassing Cancer
In the US, there are close to 3 million AR infections that kill 50,000 people a year. And more than a million deaths globally of all ages and genders. If the trend is not reversed, AR microbial infections will become harder to treat and will likely surpass cancer as the leading cause of worldwide death by 2050.
