Life Has A New Ingredient

Our prehistoric Earth, bombarded with asteroids and lightening, rife with bubbling geothermal pools, may not seem hospitable today. But somewhere in the chemical chaos of our early planet, life did form.

Scientists at the Institute for Research in Biomedicine (IRB Barcelona) have found an explanation for a periodicity in the sequence of the genomes of all eukaryotes, from yeast to humans.

Transformation in Nucleoside Analogues

Scientists have reported a theoretical and experimental characterization of DHPT (N(1)‐(2′,3′‐dihydroxypropil)thymine). DHPT is a potential prebiotic nucleoside analogue for the molecule 5-methyluridine.

Bacterial classification has been given a complete makeover by a team of University of Queensland researchers, using an evolutionary tree based on genome sequences.

All living things use the genetic code to "translate" DNA-based genetic information into proteins, which are the main working molecules in cells. Precisely how the complex process of translation arose in the earliest stages of life on Earth more than four billion years ago has long been mysterious, but two theoretical biologists have now made a significant advance in resolving this mystery.

Scientists Discover "Legos of Life"

Rutgers scientists have found the "Legos of life" - four core chemical structures that can be stacked together to build the myriad proteins inside every organism - after smashing and dissecting nearly 10,000 proteins to understand their component parts.

A dawning field of research, artificial biology, is working toward creating a genuinely new organism.

The three domains of life - archaea, bacteria, and eukarya - may have more in common than previously thought. Over the past several years, Ariel Amir, Assistant Professor in Applied Mathematics at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has been studying how cells regulate size.

A new study finds that viruses share some genes exclusively with cells that are not their hosts.

Prior to the origin of simple cellular life, the building blocks of RNA (nucleotides) had to form and polymerize in favourable environments on the early Earth.
