A fly lamin gene is both like and unlike human genes
Lamins are intermediate filament proteins that make up a matrix underlying the nuclear membrane. view more (2007-06-13)
Evolutionary battle scars' identify enhanced antiviral activity
Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms. view more (2008-01-25)
Short RNAs show a long history
MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years. view more (2008-10-02)
Which came first: Primates' ability to see colorful food or see colorful sex?
The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists. view more (2007-06-27)
Scorpion biodiversity
Scorpions possess resistance to high temperatures and the ability to conserve water for long periods of time, and as a result thrive in hot and arid parts of the world. view more (2009-04-10)
How E. coli evolves to adapt to changing acidity
Forthcoming in Physiological and Biochemical Zoology, a fascinating new selection of papers collects leading experimental research in evolution and artificial selection, providing insight into how organisms adapt to changing environmental conditions and fluctuations. view more (2007-05-30)
When animals evolve on islands, size doesn't matter
A theory explaining the evolution of giant rodents, miniature elephants, and even miniature humans on islands has been called into questions by new research published today in Proceedings of the Royal Society B: Biological Sciences. view more (2007-11-07)
Species evolve to the brink of evolution
A biologist at The University of Texas at Austin has presented a new theory that sheds light on how organisms, including viruses like HIV, rapidly evolve in the face of vaccines and antibiotics. view more (2005-08-29)
A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases. view more (2007-12-21)
Human-chimp difference may be bigger
Approximately 6 percent of human and chimp genes are unique to those species, report scientists from Indiana University Bloomington and three other institutions. view more (2006-12-20)
Evolutionary 'battle scars' identify enhanced anti-viral activity
Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center. view more (2008-01-25)
Gene expression in alligators suggests birds have 'thumbs'
The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE. view more (2008-10-06)
The aye-ayes have it: The preservation of color vision in a creature of the night
A quest to gain a more complete picture of color vision evolution has led Biodesign Institute researcher Brian Verrelli to an up-close, genetic encounter with one of the world's most rare and bizarre-looking primates. view more (2007-09-05)
How did bilaterally symmetric flowers evolve from radially symmetric ones?
The researchers found that plants bearing bilaterally symmetrical flowers were more visited by pollinators and had higher fitness, measured by both the number of seeds produced per plant and the number of seeds surviving to the juvenile stage, than plants with radially symmetric flowers. view more (2006-10-03)
UCSD Study Shows Junk DNA Has Evolutionary Importance
Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD. view more (2005-10-20)
Titania nanoparticles could lead to improved sensors and solar energy
Nanostructured titania (TiO2) has been extensively studied as a very promising material for applications in sensors, photocatalysis, solar energy conversion and optical coatings. view more (2005-12-06)
Important Genetic Research Involving Pseudogenes at Children's Hospital of Pittsburgh Reinforces Theory of Evolution
Scientists led by a Children's Hospital of Pittsburgh geneticist have found new evidence that a category of genes known as pseudogenes serve no function, an important finding that bolsters the theory of evolution. view more (2006-08-02)
Video game Everquest 2 provides new way to study human behavior, says U of Minnesota researcher
Can researchers study the populations of online video games, like Everquest 2, just as they study traditional communities like Miami, Pittsburgh or Minneapolis? view more (2009-03-02)
Lack of potential mates has lead to "sloppy" gene control and risk of disease for humans
Our evolutionary ancestors' lack of choice in the mating game has left modern humans exposed to disease, according to new research published in the journal PLOS Biology tomorrow (Tuesday 25 January 2005). view more (2005-01-24)
Experimental evolution in robots probes the emergence of biological communication
Using an ingenious approach involving virtual robots that possess evolvable genomes, researchers have identified key factors that may play important roles in determining the manner in which communication arises during the evolution of social organisms. view more (2007-02-23)
