A Pioneer Presses Search For 'Other Side of Biology'
Gerald Edelman | Nov 13, 1988 | 4 min read
When I was a high school student, I came across Erwin Schrödingers What Is Life?. I still remember my exultant reaction—a combination of adolescent pride in feeling able to understand ideas considered beyond a young person’s means, and a genuine intellectual thrill engendered by the problems that Schrödinger addressed. Upon rereading the book, it appears to me that its major value was to provoke interest in a central problem of biology. Schrödinger’s question

Editor's Note: The news items on this page all originated from the American Association for the Advancement of Science annual meeting in Anaheim, Calif., Jan. 21-26. PLAQUE ATTACK A host of studies have bitten off the task of linking periodontitis with coronary heart disease. But without more evidence, scientists may find any cause-and-effect relationship between tooth disease and heart attacks hard to swallow, admitted James D. Beck, professor of dental ecology, at the University of North Caro

Surpassing the Law of Averages
Jeffrey M. Perkel | Sep 1, 2009 | 7 min read
By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

Horizontal Gene Transfer Happens More Often Than Anyone Thought
Christie Wilcox, PhD | Jul 5, 2022 | 10+ min read
DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.
The Genetics of Society
Claire Asher and Seirian Sumner | Jan 1, 2015 | 10 min read
Researchers aim to unravel the molecular mechanisms by which a single genotype gives rise to diverse castes in eusocial organisms.

Embryonic Eavesdropping: How Animals Hear and Respond to Sound
Amanda Heidt | Nov 1, 2021 | 10+ min read
Recent findings buck the traditional idea that embryos are passive agents and instead suggest that by tuning into vibrations, organisms can better prepare to enter the outside world.
Ribozymes: Hearkening Back to an RNA World
Jeffrey Perkel | Sep 15, 2002 | 9 min read
Illustration: Ned Shaw LIKE MOLECULAR TOY-MAKERS, ribozyme researchers create tools with evolutionary, diagnostic, and therapeutic applications. Nearly 20 years ago, Tom Cech and Sidney Altman discovered that some naturally occurring RNAs could perform enzymatic reactions, earning these researchers the 1989 Nobel Prize in chemistry. Scientists have now identified several examples of RNA enzymes, or ribozymes. Most make or break the phosphodiester bonds in nucleic acid backbones, but some
Touching RNA
Anna Marie Pyle | Sep 1, 2010 | 10+ min read
By Anna Marie Pyle TOUCHING RNA RNA can bind and sense the shapes of other molecules by feeling them with its backbone— and not just its bases. What gives RNA molecules this remarkable versatility? Illustrations by Magda Wojtyra he molecular world has always been part of my mental furniture. I grew up on the outskirts of Sandia National Laboratory in Albuquerque, New Mexico, famed for its research on energy, materials, and nuclear weapons. My dad was a
Targeting Antibiotic-Resistant Bacteria with CRISPR and Phages
