Before sending humans to Mars or the moon, scientists need to understand what long-term space living does to the human body. Now results are coming in from the Kelly brothers in the TWINS Study,
Cancer is a disease of our genes, but resistance to therapy might go beyond cancer mutations. The DNA stays the same, but cancer cells outsmart the drugs by switching their gene activity.
A field called epigenomics looks at chemical modifications that do not change our DNA sequence but can affect gene activity. What are the limitations, and can biomedicine use this to our advantage?
