Positions of Genes Inside the Cell Nucleus Exert Biological Effects: Scientific American
the structure of nuclear components—chromosomes, RNA, protein complexes and other small bodies—could be as biologically important as the components themselves.
Salty Origins For Early Earth Biomolecules
In a study presented at the European Planetary Science Conference in Potsdam, researchers proposed that salt deposits on the early Earth's volcanic coasts enabled the conversion of amino acids into other important molecules for the start of life.

A recent interview with E. O. Wilson
Is free will an illusion?
This debate has focused on humans and 'conscious free will'. Yet when it comes to understanding how we initiate behaviour, we can learn a lot by looking at animals. Although we do not credit animals with anything like the consciousness in humans, researchers have found that animal behaviour is not as involuntary as it may appear. The idea that animals act only in response to external stimuli has long been abandoned, and it is well established that they initiate behaviour on the basis of their internal states, as we do.

Science Functional Genomics Resources: Epigenetics
To provide an extra dimension to coverage in the 10 August 2001 special issue, we're launching a new epigenetics section here on the Science Functional Genomics Web site. On this page, you'll find a collection of links to interesting Web resources on chromatin, methylation, imprinting, and a variety of other topics with an epigenetics bend. Also, we've gathered together a selection some groundbreaking research papers, Reviews, and Perspectives published in Science over the past five years, in a special new epigenetics section of our Functional Genomics Research Archive.

Do Gay Animals Change Evolution?
Animals that engage in same-sex sexual behavior may be acting in accord with adaptational strategies rather than against them--and bending the way we think about evolution (Scientific American)
RNA World
The origins of life on earth remains a daunting scientific challenge. The difficulty is in trying to find evidence to infer what chemical reactions took place billions of years ago. There may ultimately be no way to settle the issue, but that does not mean the question cannot be addressed scientifically. (NeuroLogica Blog)
In The Prebiotic Kitchen
To explain the origin of life, scientists seek to explain the origin of its components. The three most important of these are RNA, DNA, and proteins. (The Loom | Discover Magazine)
The Origin of Life
In this article we present a view gaining attention in the origin-of-life community that takes the question out of the hatchery and places it squarely in the realm of accessible, plausible chemistry. As we see it, the early steps on the way to life are an inevitable, incremental result of the operation of the laws of chemistry and physics operating under the conditions that existed on the early Earth, a result that can be understood in terms of known (or at least knowable) laws of nature. As such, the early stages in the emergence of life are no more surprising, no more accidental, than water flowing downhill.
Extending Darwinism
Lamarck proposed two mechanisms of evolutionary change: an inherent tendency in living matter to become increasingly more complex and the inheritance of acquired characteristics — environmentally induced or learned individual adaptations that accrue over time and pass to offspring. Many biologists at the time, including Darwin himself, believed such “soft” inheritance was complementary to the theory of natural selection.
What is Epigenetics? An operational definition
So what exactly is epigenetics? On a recent meeting (last December) on chromatin-based epigenetics, hosted by the Banbury Conference Center (a beautiful place) and Cold Spring Harbor Laboratory, several aspects of epigenetic control of gene expression and function were discussed and there was an intent to arrive at a consensus definition of epigenetics to be considered by the broader community.
