Scientists Solve Major Piece in the Origin of Biological Complexity

Scientists have puzzled for centuries over how and why multicellular organisms evolved the almost universal trait of using single cells, such as eggs and sperm, to reproduce. Now researchers led by University of Minnesota College of Biological Sciences postdoctoral fellow William Ratcliff and associate professor Michael Travisano have set a big piece of that puzzle…

Did Inefficient Cellular Machinery Evolve to Fight Viruses and Jumping Genes?

It might seem obvious that humans are elegant and sophisticated beings in comparison to lowly bacteria, but when it comes to genes, a UC San Francisco scientist wants to turn conventional wisdom about human and bacterial evolution on its head. Far from being sleekly performing and fine-tuned athletes, the molecules guiding the activity of our…

Novel Genetic Patterns May Make Us Rethink Biology and Individuality

Professor of Genetics Scott Williams, PhD, of the Institute for Quantitative Biomedical Sciences (iQBS) at Dartmouth's Geisel School of Medicine, has made two novel discoveries: first, a person can have several DNA mutations in parts of their body, with their original DNA in the rest -- resulting in several different genotypes in one individual --…

New Challenges in the Fast Changing Landscape of Bioinformatics

The world of DNA sequencing and bioinformatics has evolved at a staggering pace. In 2009, the biggest problem for researchers was creating an efficient solution for sequencing DNA. At that time, sequencing cost of $100,000 for a single human and took 30 days of chemical processing to produce the raw sequencing output. In four years,…

Model Virus Structure Shows Why There’s No Cure for Common Cold

In a pair of landmark studies that exploit the genetic sequencing of the “missing link” cold virus, rhinovirus C, scientists at the University of Wisconsin-Madison have constructed a three-dimensional model of the pathogen that shows why there is no cure yet for the common cold. Writing today (Oct. 28, 2013) in the journal Virology, a…

Visions of the Everglades: History Ecology Preservation

A wise man named Gaius Plinius Secundus once said, “Home is where the heart is.” Well, South Florida is my home, and my heart lies in its rich, vast wilderness. I am a nature enthusiast with a background in computational biology. My passion for science and nature is self-evident; indeed, it is a passion for…

Hitchhiking Virus Confirms Saga of Ancient Human Migration

A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome. The virus under study, herpes simplex virus type 1 (HSV-1), usually causes nothing more severe than cold sores around…

Jobs for a Masters Degree in Bioinformatics

Bioinformatics is a branch of biotechnology that uses computer technology and other methods to manage and analyze biological data. Those who hold a master's degree in bioinformatics typically use a combination of mathematics, statistics, computer science and biological research data to further scientific studies. One example of a large-scale bioinformatics project is the Human Genome…
