Cancer Without Chemotherapy: ‘A Totally Different World’
A growing number of cancer patients, especially those with breast and lung cancers, are being spared the dreaded treatment in favor of other options.
The Complex Truth About ‘Junk DNA’
Genomes hold immense quantities of noncoding DNA. Some of it is essential for life, some seems useless, and some has its own agenda.

The Latest on COVID-19 Boosters
More than 180 million Americans, including more than 80 percent of people over age 65, are fully vaccinated against the SARS-CoV-2 virus responsible for COVID-19. There’s no question that full vaccination is the best way to protect yourself against this devastating virus and reduce your chances of developing severe or long-lasting illness if you do get sick. But, to stay ahead of this terrible virus, important questions do remain. A big one right now is: How soon will booster shots be needed and for whom?
