Evolution can occur in less than 10 years
How fast can evolution take place? In just a few years, according to a new study on guppies led by UC Riverside's Swanne Gordon, a graduate student in biology. view more (2009-06-11)
Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies. view more (2007-11-15)
Evolutionary harmony for stinkbugs and their gut bacteria: A perfect match
With some 1 million species and counting, insects may be the most abundant class of animals living today. Their protective exoskeleton, prolific reproductive rate, and wings help their cause, as do the symbiotic bacteria that inhabit their cells, gut, or body cavity. view more (2006-10-10)
Origins of nervous system found in genes of sea sponge
Scientists at the University of California, Santa Barbara have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge, a member of a group considered to be among the most ancient of all animals. view more (2007-06-06)
MicroRNAs have shaped the evolution of the majority of mammalian genes
RNA continues to shed its reputation as DNA's faithful sidekick. Now, researchers in the lab of Whitehead Institute Member David Bartel have found that a class of small RNAs called microRNAs influence the evolution of genes far more widely than previous research had indicated. view more (2005-11-30)
UK Astronomers Survey Galactic Graveyard
An unprecedented source of planetary nebulae, the disk-like relics of elderly, dying stars, has been discovered in the southern part of our Milky Way galaxy. With about 1000 planetary nebulae found so far and many more still to be discovered, the number of aged stars in their death throes revealed by the new survey is rapidly overtaking the entire... view more...

New recipe for dwarf galaxies: Start with leftover gas
There is more than one way to make a dwarf galaxy, and NASA's Galaxy Evolution Explorer has found a new recipe. view more (2009-02-19)
Sperm proteome gives "tantalising glimpse" towards the origin of sex
The first ever catalogue of the different types of proteins found in sperm could help reveal the origins of sex and explain some of the mysteries of infertility, say scientists. view more (2006-11-13)
St. Jude conducts first large-scale bird flu genome study
Unique resources at St. Jude Children's Research Hospital let researchers generate a "gold mine" of data to track evolution of bird flu virus genes and understand how they cooperate to cause disease. view more (2006-01-27)
Biologists ID molecular basis of high-altitude adaptation in mice
Biologists have long known how adaptive evolution works. New mutations arise within a population and those that confer some benefits to the organism increase in frequency and eventually become fixed in the population. view more (2009-08-11)
IU astronomer's discovery poses challenge to galaxy formation theories
A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest they may have formed relatively recently. view more (2009-04-13)
LSU professor involved in genome sequencing of the first marsupial
Since the launch of the Human Genome Project, which released a first draft of the entire sequence of human DNA in 2001, many researchers have dedicated themselves to creating a library of comprehensive, species-specific genetic sequence "maps" available for study. view more (2007-05-10)
First RAVE data release offers clues to Milky Way evolution
An international team of astronomers released to the public the first data collected as part of the Radial Velocity Experiment, an ambitious spectroscopic survey aimed at measuring the speed, temperature, surface gravity and composition of up to a million stars passing near the sun. view more (2006-02-13)
A solution to Darwin's 'mystery of the mysteries' emerges from the dark matter of the genome
Biological species are often defined on the basis of reproductive isolation. Ever since Darwin pointed out his difficulty in explaining why crosses between two species often yield sterile or inviable progeny (for instance, mules emerging from a cross between a horse and a donkey), biologists have struggled with this question. view more (2009-10-27)
Iberia was the European demographic reservoir during the last Ice Age
By studying mitochondrial DNA, which is passed from mother to child, researchers have found that most of the actual European inhabitants seem to have come from re-expansion of hunter-gatherers populations, which have migrated from Iberia, Europe after the end of the last Ice Age reports an article in the January issue of Genome Research. view more (2005-01-12)
Evolution coup: Study reveals how plants protect their genes
Unlike animals and humans, plants can't run and hide when exposed to stressful environmental conditions. So how do plants survive? view more (2009-09-11)
Robust time estimation reconciles views of the antiquity of placental mammals
Despite great progress over the past decade, the evolutionary history of placental mammals remains controversial. While a consensus is emerging on the topology of the evolutionary tree, although with occasional disagreement, divergence times remain uncertain. view more (2007-04-18)
Researchers successfully simulate photosynthesis and design a better leaf
University of Illinois researchers have built a better plant, one that produces more leaves and fruit without needing extra fertilizer. The researchers accomplished the feat using a computer model that mimics the process of evolution. Theirs is the first model to simulate every step of the photosynthetic process. view more (2007-11-12)
Facial attraction -- choice of sexual partner shaped the human face
Men with large jaws, flaring cheeks and large eyebrows are sexy, at least in the eyes of our ancestors, researchers at the Natural History Museum have discovered. view more (2007-08-14)
Folding wings - just the business for insect survival
Just like modern businesses, insects have had to diversify to survive, according to University of York scientist Peter Mayhew. The ability to fold their wings is one device they have adopted over the years as part of the struggle for survival, says Dr Mayhew. And folding wings have given the insects which adopted them - including bugs, beetles,... view more... (2002-05-01)
