UGA researchers propose new hypothesis on the evolution of hot springs microorganisms
Since their discovery in the late 1970s, microorganisms known as archaea have fascinated scientists with their ability to thrive where no other life can — in conditions that are extremely hot, acidic or salty. view more (2006-06-06)
Secret of eternal youth may be in reptiles
Jo'£o Pedro Magalh'£es, researcher in the Biology of Aging, suggests, in work published in the June edition of the magazine "Experimental Gerontology" and entitled "The evolution of mammalian aging", that the study of certain species of reptiles and amphibians that apparently do not age could lead to discoveries about aging. For this... view more... (2002-06-18)
Americans less likely to accept evolution than Europeans
Surveys by a Michigan State University researcher find that about one-third of the American population does not believe in evolution, a figure which is much higher than those found in similar surveys in European nations and Japan. view more (2006-08-14)
Ocean growing more acidic faster than once thought
University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide. view more (2008-11-25)
Fossil discovery marks earliest record of limbloss in ancient lizard
A University of Alberta paleontologist has helped discover the existence of a 95 million-year-old snakelike marine animal, a finding that provides not only the earliest example of limbloss in lizards but the first example of limbloss in an aquatic lizard. view more (2007-03-23)
Unique Coastal Defence Research
'We will be comparing the 3D beach evolution and sediment transport in the CRF model with measurements made on the Sussex coast at Elmer, on which the model is based,' explains Dr Chadwick, Reader in Coastal Engineering. 'The CRF data will also be compared against calculations of beach evolution and sediment transport derived from numerical... view more... (1998-12-23)
How did cactuses evolve?
In a groundbreaking new study in the June issue of American Naturalist, Erika J. Edwards (Yale University and University of California, Santa Barbara) and Michael J. Donoghue (Yale University) explore how leafy, "normal" plants evolved into the leafless succulent cactus. view more (2006-05-15)
Man's best friend lends insight into human evolution
Flexibly drawing inferences about the intentions of other individuals in order to cooperate in complex tasks is a basic part of everyday life that we humans take for granted. view more (2007-03-02)
Real super-bugs can save the planet - Microbiology Today: November 2004 issue
Beneficial bacteria have fast-tracked evolution to solve some of our pollution problems, according to an article in the November 2004 issue of Microbiology Today, the quarterly magazine of the Society for General Microbiology. Using the same mechanisms that have allowed hospital superbugs to survive in the presence of antibiotics, many bacteria... view more... (2004-10-26)
A new male-specific gene in algae unveils an origin of male and female
By studying the genetics of two closely related species of green algae that practice different forms of sexual reproduction, researchers have shed light on one route by which evolution gave rise to reproduction though the joining of distinct sperm and egg cells. view more (2006-12-19)
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)
Amphibians in losing race with environmental change
Even though they had the ability to evolve and survive for hundreds of millions of years - since before the time of the dinosaurs and through many climatic regimes - the massive, worldwide decline of amphibians can best be understood by their inability to keep pace with the current rate of global change, a new study suggests. view more (2007-05-01)
Darwin's greatest challenge tackled: the mystery of eye evolution
When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye evolved through spontaneous mutation and natural selection. Scientists at the European Molecular Biology Laboratory (EMBL) have now tackled Darwin's major challenge in an... view more... (2004-10-26)
St. Bernard study casts doubt on creationism
The St Bernard dog - named after the 11th century priest Bernard of Menthon - may have ironically challenged the theory of creationism, say scientists. view more (2007-10-24)
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)
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)
Novel experiment documents evolution of genome in near-real time
A team led by bioengineering researchers at UC San Diego report in the November issue of Nature Genetics rapid evolutionary changes in a bacterial genome, observed in near-real time over a few days. view more (2006-11-06)
Genome archaeology illuminates the genetic engineering debate
Genome Research's cover story for Oct. 2 tells a tale of "genome archaeology" by genetic researchers who dug deeply into the long history of maize and rice. view more (2006-10-04)
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)
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)
