Fatherless Snakes
Boa constrictors are the latest addition to the list of vertebrate species in which parthenogensis, or asexual reproduction, has been documented.
HIV Controllers
A small minority of people can fight the HIV virus with their own immune systems. A new study identifies just a few genetic differences that set them apart from those for who the disease has progressed.
Podcast
A genetic explanation for why some people with the HIV virus never develop symptoms, how the shape of the genome influences how genes work, and a religious practice that's shaping the evolution of a Mexican fish. Also: cloud seeding gets a failing grade, and why replacing native plants with crops accelerates climate change.
Light-Smelling Mice
Mice that can smell light help neurobiologists study olfaction.

Brain Clutter
An inability to clean up cellular waste may contribute to Parkinson's disease.
Flamingo Makeup
Just being pink isn't good enough for a flamingo. A new study reveals that they apply makeup to their feathers to stand out even more.
Ant Epigenetics
In some ant species, queens and workers are genetically identical. A new study reveals how they develop different behaviors and appearance.
Extreme Longevity
Researchers have identified some genetic similarities in people who live for over 100 years.
