Today, vaccinating against cervical cancer is routine. But before Sarah Stewart, scientists dismissed the idea of a cancer-preventing vaccine as ludicrous

A digitally-colorized scanning electron micrograph depiction of a Giardia lamblia protozoan caught in a late stage of cell division, producing a heart-shaped form. Most protozoa, or singled-celled eukaryotes, reproduce asexually, but there is evidence to suggest Giardia lamblia can reproduce sexually as well.

The Evolution of Sex Could Have Provided a Defense Against Cancer Cells

The first sexually reproducing organisms may have found that the energy-intensive enterprise bolstered defenses against malignant cells

Researchers looked at smell tests taken by more than 2,200 people between the age of 71 and 82 years old.
