Non-Standard Bonding in Base Pairs

A new study provides insight into base pair bonding in artificial DNA polymerase. Researchers focused on a previously unknown base pair: iso-guanine and methyl-pyrimidinone.

Earth's Viral Diversity

The number of microbes in, on, and around the planet - on the order of a nonillion, or 10^30 - is estimated to outnumber the stars in the Milky Way.

Recreating A Primordial RNA World

Scientists at The Scripps Research Institute (TSRI) have taken a big step toward the laboratory re-creation of the "RNA world," which is generally believed to have preceded modern life forms based on DNA and proteins.

The relatively recent development of high-throughput sequencing (HTS) techniques has revealed a wealth of novel sequences found in very low abundance: the rare biosphere.

A new study could explain why DNA and not RNA, its older chemical cousin, is the main repository of genetic information.

Researchers from the J. Craig Venter Institute (JCVI) and Synthetic Genomics, Inc. (SGI) announced today the design and construction of the first minimal synthetic bacterial cell, JCVI-syn3.0.

NASA-funded researchers at the Georgia Institute of Technology are tapping information found in the cells of all life on Earth, and using it to trace life's evolution.

Oldest Known Redox Gradient Discovered

By analyzing iron isotopes against the uranium content in the jasper rock from the ancient ocean of the Barberton Greenstone Belt in South Africa, scientists have found a defined vertical redox gradient, called a redoxcline, showing a change in the level of oxygenation from the deeper part of the ocean leading to the shallower portion.

Tree of Life for 2.3 Million Species Released

A first draft of the "tree of life" for the roughly 2.3 million named species of animals, plants, fungi and microbes -- from platypuses to puffballs -- has been released.

Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get.

Hydrogen peroxide -- commonly used as hair bleach -- may have provided the energy source for the development of life on Earth, two applied mathematicians have found.

Together with colleagues from Uppsala University in Sweden and the University of Vienna in Austria, Steffen Leth Jrgensen from the Centre for Geobiology at the University of Bergen (UiB) has published the article Complex Archaea that bridge the gap between prokaryotes and eukaryotes in Nature, presenting the discovery of this new microbe.

Ideas about directing evolution of life forms on Earth and finding life on other planets are rapidly morphing from science-fiction fantasy into mainstream science, says David Lynn, a chemist at Emory University.

Sounding rockets represent an excellent platform for testing the influence of space conditions during the passage of Earth's atmosphere and re-entry on biological, physical and chemical experiments for astrobiological purposes.

Two Northeastern University researchers and their international colleagues have created an advanced model aimed at exploring the role of neutral evolution in the biogeographic distribution of ocean microbes.

Parts of the primordial soup in which life arose have been maintained in our cells today according to scientists at the University of East Anglia.

Scientists at The Scripps Research Institute have engineered a bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature. The cells of this unique bacterium can replicate the unnatural DNA bases more or less normally, for as long as the molecular building blocks are supplied.

If you have been watching the new series "Cosmos" recently then you have see Tardigrades or "water bears" featured. These creatures are remarkably resistant to a wide range of conditions that humans would consider extreme - if not deadly.

Capitalizing on the ability of an organism to evolve in response to punishment from a hostile environment, scientists have coaxed the model bacterium Escherichia coli to dramatically resist ionizing radiation and, in the process, reveal the genetic mechanisms that make the feat possible.

Simply making nanoparticles spin coaxes them to arrange themselves into what University of Michigan researchers call 'living rotating crystals' that could serve as a nanopump. They may also, incidentally, shed light on the origin of life itself.
