Woese Undergraduate Scholars set for a summer of science

July 16, 2019

Two of the most basic motivations that drive scientific research—exploration of the unknown and the desire to solve a pressing problem—are represented by this year’s Carl R. Woese undergraduate research scholars. Allison Narlock will spend her summer investigating the mechanics of archaeal cell division; Monika Ziogaite will be working to identify genetic variants that contribute to the metastatic potential of breast cancers.

Study of archaeal cells could teach us more about ourselves

January 24, 2019

Forty-two years after Carl Woese defined archaea as the third domain of life, scientists at the IGB are still learning about these ancient organisms in ways that could help us learn more about eukaryotes.

Over time, scientists have realized that archaea have close ancestral relationships to eukaryotes — the domain of life that includes animals, plants, and more.

Viruses share genes with organisms across the tree of life

December 7, 2017

A new study finds that viruses share some genes exclusively with cells that are not their hosts. The study, reported in the journal Frontiers in Microbiology, adds to the evidence that viruses swap genes with a variety of cellular organisms and are agents of diversity, researchers say.

The study looked at protein structures in viruses and across all superkingdoms, or domains, of life: from the single-celled microbes known as bacteria and archaea, to eukaryotes, a group that includes animals, plants, fungi and all other living things.

Team discovers microbes speciating

February 22, 2012

Not that long ago in a hot spring in Kamchatka, Russia, two groups of genetically indistinguishable microbes parted ways. They began evolving into different species – despite the fact that they still encountered one another in their acidic, boiling habitat and even exchanged some genes from time to time, researchers report. This is the first example of what the researchers call sympatric speciation in a microorganism.
