In this article, I was surprised to read that chimeras harboring a mutation are not medically useful. Consider the value of cytokine-receptor mutations in humans, with respect to HIV. It’s likely that introducing some genetic mutations can inhibit viruses or bacteria in a host. Freda Wasserstein Robbins New Jersey City University Jersey City, N.J.

Letting the Dog Genome Out: Poodle DNA compared with that of mice, people
Biologists have deciphered the DNA sequence of a poodle, an accomplishment that may help researchers study more than 300 human diseases that also affect dogs.

Out of China: SARS virus’ genome hints at independent evolution
The newly identified SARS virus is the product of a long and private evolutionary history, clues from its genome suggest.

I was intrigued by the fact that some apoptotic cells can recover if not engulfed by another cell. DNA reassembly after the caspases tear it apart should result in many gene mutations. While most of the mutations would result in cell death, perhaps a few cells would have mutations that promote a cancerous or precancerous […]

Retaking Flight: Some insects that didn’t use it didn’t lose it
Stick insects may have done what biologists once thought was impossible: lose something as complicated as a wing in the course of evolution but recover it millions of years later.

New World Newcomers: Men’s DNA supports recent settlement of the Americas
New data on genetic differences among the Y chromosomes of Asian and Native American men support the notion that people first reached the Americas less than 20,000 years ago.
