It depends heavily on the role. A bachelor's degree (three to four years) is enough for many entry-level research or field positions. Becoming an independent principal investigator who runs a lab typically takes far longer: roughly four years of undergraduate study, five to six years for a PhD, and often several more years of postdoctoral research before a permanent position.
A physician diagnoses and treats human patients directly, using a medical degree focused on clinical practice. A biologist studies living systems more broadly — genes, cells, organisms, ecosystems — often without ever treating a patient, though biomedical researchers frequently work alongside physicians to develop the drugs, vaccines and diagnostic tools doctors later use in the clinic.

It varies enormously by country, sector and specialty. In the United States, biological scientists earned roughly $85,000 on average in 2023, according to the Bureau of Labor Statistics, though senior biotech-industry scientists and pharmaceutical executives earn considerably more. Academic salaries in much of Europe and Asia tend to run lower than US industry pay for comparable seniority.
CRISPR-Cas9 is a gene-editing tool adapted from a bacterial immune system that normally cuts up invading viral DNA. Jennifer Doudna and Emmanuelle Charpentier showed in 2012 that it could be reprogrammed to cut any chosen DNA sequence in any organism, making precise genome editing dramatically faster and cheaper than earlier methods — work that won them the 2020 Nobel Prize in Chemistry.
