By Michele Pagano have always gravitated toward order. I may even take it a bit too far according to friends who liken my office to a museum. However, I like to think it not a compulsion, but a Feng Shui approach to life. With this need for order, I may have been better suited to

The Genome Project Holds Promise, But We Must Look Before We Leap
Joshua Lederberg | Mar 19, 1989 | 3 min read
To an ever-increasing degree, explanation in biology is reduced to art expression in the language of DNA sequences. At least, a necessary condition for the interpretation of many problems in evolution, genetics, virology, immunology teratology, or cancer is the elucidation of a message in the well-known ATGC alphabet. Furthermore, the power of biotechnology rests on manufacturing blueprints of the same ilk. To a degree " unprecedented in biological history, we can describe the agenda for much
The Out-of-Hand Omnipresent Ome
Thomas Mennella | Jun 15, 2003 | 4 min read
In 1909, the Danish biologist Wilhelm Johannsen coined the terms gene, to describe the unit of heredity, and genotype as the entire genetic profile of an organism. Seven years later, the term biome appeared, used to describe an ecological community of organisms and environments. As technology progressed, it became possible to do high-throughput molecular biology, and we began exploring the genomes of various microbes. This essentially entailed sequencing and annotating the entire genetic com

Bacterial Enzyme Keeps Rotifers’ Transposable Elements in Check
Christie Wilcox, PhD | Mar 3, 2022 | 5 min read
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
