Native Americans Descended From a Single Ancestral Group, DNA Study Confirms
For two decades, researchers have been using a growing volume of genetic data to debate whether ancestors of Native Americans emigrated to the New World in one wave or successive waves, or from one ancestral Asian population or a number of different populations. view more (2009-04-29)
Elderly patients can benefit from selective use of early revascularization
The elderly represent a growing proportion of patients presenting with acute myocardial infarction (MI) complicated by cardiogenic shock (CS). view more (2009-02-17)
Moving gene therapy forward with mobile DNA
Gene therapy is the introduction of genetic material into a patient's cells resulting in a cure or a therapeutic effect. In recent years, it has been shown that gene therapy is a promising technology to treat or even cure several fatal diseases for which there is no attractive alternative therapy. view more (2009-05-04)
Make your millions - turning science into business
Funded and co-ordinated by the Natural Environment Research Council (NERC), the competition is open to all publicly funded scientists investigating the natural environment who wish to see their research developed into a commercial business proposition. Entries are welcome from individuals or teams, who will need to submit an outline business idea... view more... (2000-03-16)
Evolutionary scrap-heap challenge: Antifreeze fish make sense out of junk DNA
Scientists at the University of Illinois have discovered an antifreeze-protein gene in cod that has evolved from non-coding or 'junk' DNA. view more (2006-04-04)
Scientists propose the creation of a new type of seed bank
While an international seed bank in a Norwegian island has been gathering news about its agricultural collection, a group of U.S. scientists has just published an article outlining a different kind of seed bank, one that proposes the gathering of wild species -- at intervals in the future -- effectively capturing evolution in action. view more (2008-10-16)
Potential treatments from cryptic genes
Big pharma gave up on soil bacteria as a source of antibiotics too soon, according to research published in the June issue of Microbiology. Scientists have been mining microbial genomes for new natural products that may have applications in the treatment of MRSA and cancer and have made some exciting discoveries. view more (2008-06-02)
Survival of the rarest: Fruit flies shed light on the evolution of behavior
Sometimes, it pays to be rare—think of a one-of-a-kind diamond, a unique Picasso or the switch-hitter on a baseball team. view more (2007-05-10)
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)
First calves from gene diagnosed embryos born at MTT Agrifood Research Finland
Results from quantitative trait gene mapping (QTL) have been utilised for the first time in the selection of bovine embryos. The genotypes of two genes affecting milk yield and composition have been analysed from pre-implantation embryo biopsies. The first four female calves with known milk production genotypes were recently born at the... view more... (2003-08-14)
How butterflies got their spots: A 'supergene' controls wing pattern diversity
Butterflies are known to employ some interesting convergent evolutionary tactics to survive-some nonpoisonous species have similar wing patterns to those of noxious species that predators avoid. view more (2006-09-26)
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)
Gene's past could improve the future of rice
In an effort to improve rice varieties, a Purdue University researcher was part of a team that traced the evolutionary history of domesticated rice by using a process that focuses on one gene. view more (2009-01-26)
New research confirms that natural selection is acting on the current human population
New evidence suggests that natural selection is leading women to have their first child at earlier ages. This is shown to be an inherited evolutionary change that is taking place despite the influence of social factors such as religion and education. The findings, by a team of British, Australian and American scientists, show for the first time... view more... (2001-04-23)
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)
Does natural selection drive the evolution of cancer?
The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer biology. view more (2006-11-20)
Women may not be so picky after all about choosing a mate
Men and women may not be from two different planets after all when it comes to choosiness in mate selection, according to new research from Northwestern University. view more (2009-06-03)
Where there's muck there's grass
The oldest ecological experiment in the world, set up almost 150 years ago to see whether inorganic fertilisers could produce more grass than traditional animal manures, is becoming an important source of evidence on the impact of climate change on genetic variation in plants. Speaking at the British Ecological Society's Annual Meeting, being... view more... (2003-09-01)
Texas-sized tract of single-celled clones
A Rice University study of microbes from a Houston-area cow pasture has confirmed once again that everything is bigger in Texas, even the single-celled stuff. The tests revealed the first-ever report of a large, natural colony of amoebae clones -- a Texas-sized expanse measuring at least 12 meters across. view more (2009-03-12)
Why do some queen bees eat their worker bee's eggs?
Worker bees, wasps, and ants are often considered neuter. But in many species they are females with ovaries, who although unable to mate, can lay unfertilized eggs which turn into males if reared. view more (2006-12-05)
