Scientists' cell discovery unearths evolutionary clues
The full family tree of the species known as social amoebas has been plotted for the first time - a breakthrough which will provide important clues to the evolution of life on earth. view more (2006-10-30)
Genetic variation: We're more different than we thought
New research shows that at least 10 percent of genes in the human population can vary in the number of copies of DNA sequences they contain-a finding that alters current thinking that the DNA of any two humans is 99.9 percent similar in content and identity. view more (2006-11-27)
Catching the common cold virus: BYU researchers coming down with the rhinovirus genome
A new study by Brigham Young University researchers on the virus behind nearly half of all cold infections explains how and where evolution occurs in the rhinovirus genome and what this means for possible vaccines. view more (2009-03-17)
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)
First observation of linkage between genes controlling resistance found in crop pests
Researchers at Clemson University, USA have found connections between resistance controlling genes in Heliothis virescens F (Tobacco budworm), a serious pest of cotton. `This linkage may contribute to the rapid evolution of resistance observed in this pest` said researcher Thomas M Brown. view more (2002-01-30)
New study of gene evolution could lead to better understanding of neurodegenerative disease
Genetic evolution is strongly shaped by genes' efforts to prevent or tolerate errors in the production of proteins, scientists at The University of Texas at Austin and Harvard University have found. view more (2008-07-25)
There's a speed limit to the pace of evolution, Penn biologists say
Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits." view more (2009-11-03)
Alligator egg development at prehistoric oxygen levels
The development of bone structures in alligator eggs raised under varying oxygen concentrations creates a link to fossil records of the evolution of vertebrates and prehistoric atmospheric oxygen concentrations, according to a paper to be presented at the Earth System Processes 2 meeting in Alberta, Canada. view more (2005-08-05)
Discovery of a molecular mechanism underlying limb architecture
A genetic study performed by Dr. Marie Kmita, a researcher at the Institut de Recherches Cliniques de Montréal (IRCM), in collaboration with Drs Basile Tarchini and Denis Duboule of the University of Geneva in Switzerland, sheds light on the origins of the architecture of arms and legs. view more (2006-10-26)
How plants learned to respond to changing environments
A team of John Innes centre scientists lead by Professor Nick Harberd have discovered how plants evolved the ability to adapt to changes in climate and environment. view more (2007-07-13)
A new control mechanism for genetic code translation discovered in bacteria
Almost all organisms, from bacteria to human beings, share the same genetic code, a group of universal instructions used to convert DNA or RNA sequences into proteins, the "building blocks" of life. view more (2008-02-15)
A new tree of life allows a closer look at the origin of species
In 1870 the German scientist Ernst Haeckel mapped the evolutionary relationships of plants and animals in the first 'tree of life'. view more (2006-03-03)
Blame Our Evolutionary Risk of Cancer on Our Body Mass
A key enzyme that cuts short our cellular lifespan in an effort to thwart cancer has now been linked to body mass. view more (2006-12-06)
Startling results from new biomedical research international conference will smooth path to the market place
Researchers have discovered how to convert liver cells of mice into pancreatic cells using a single injection. This may eventually lead to a cure for diabetes. Dr. James Mittra, one of the organisers of an international conference in Edinburgh on the Evolution of the Life Science Industries asks, "How does the pharmaceutical industry respond... view more...

Astronomers find the most distant star clusters hidden behind a nearby cluster
Astronomers have discovered the most distant population of star clusters ever seen, hidden behind one of the nearest such clusters to Earth. view more (2007-01-11)
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)
Pitt professor contends biological underpinnings
Jeffrey H. Schwartz, University of Pittsburgh professor of anthropology in the School of Arts and Sciences, is working to debunk a major tenet of Darwinian evolution. view more (2007-02-12)
'Hobbit' fossils represent a new species, concludes University of Minnesota anthropologist
University of Minnesota anthropology professor Kieran McNulty (along with colleague Karen Baab of Stony Brook University in New York) has made an important contribution toward solving one of the greatest paleoanthropological mysteries in recent history -- that fossilized skeletons resembling a mythical "hobbit" creature represent an... view more...

Annuals converted into perennials
Annual crops grow, blossom and die within one year. Perennials overwinter and grow again the following year. The life strategy of many annuals consists of rapid growth following germination and rapid transition to flower and seed formation, thus preventing the loss of energy needed to create permanent structures. view more (2008-11-10)
A Glimpse of the Very Early Universal Web
The VLT Maps Extremely Distant Galaxies New, trailblazing observations with the ESO Very Large Telescope (VLT) at Paranal lend strong support to current computer models of the early universe: It is "spongy", with galaxies forming along filaments, like droplets along the strands of a spiders web. A group of astronomers at ESO and in Denmark... view more... (2001-05-18)
