Iowa State researcher studies gene families to explore diversity and evolution
Theoretical biologist Stephen Proulx studies gene families to explore how genomes become diverse and evolve. view more (2006-08-01)
Insight into our sight: A new view on the evolution of the eye lens
The critical component in focusing is the eye lens, and the physical properties that underlie the transparency of the lens, as well as its ability to precisely refract light, arise from the high concentrations of special proteins called crystallins found in lens cells. view more (2005-09-23)
The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. view more (2007-08-28)
Human culture subject to natural selection, Stanford study shows
The process of natural selection can act on human culture as well as on genes, a new study finds. view more (2008-02-19)
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)
Primate culture is just a stone's throw away from human evolution, study finds
For 30 years, scientists have been studying stone-handling behavior in several troops of Japanese macaques to catch a unique glimpse of primate culture. view more (2009-01-13)
A new tribe at the BA festival
A new tribe is emerging from Mexico's scorched earth. A team of geoarchaeologists working on a programme investigating human evolution have found skeletal remains in the desert of the Baja California Peninsula that give rise to new theories on the colonisation of the Americas. view more (2004-09-03)
Remembrance of things past influences how female field crickets select mates
UC Riverside biologists researching the behavior of field crickets have found for the first time that female crickets remember attractive males based on the latter's song, and use this information when choosing mates. view more (2009-04-22)
Fruitfly study shows how evolution wings it
In the frantic world of fruitfly courtship, the difference between attracting a mate and going home alone may depend on having the right wing spots. view more (2006-04-20)
Study finds human population expanded during late Stone Age
Genetic evidence is revealing that human populations began to expand in size in Africa during the Late Stone Age approximately 40,000 years ago. view more (2009-07-29)
Animals can change genes quickly to keep up with viral ingenuity
Viruses are famous for evolving quickly, but the organisms they infect can't be expected to sit idly by. view more (2006-03-21)
Forced evolution: Can we mutate viruses to death?
It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence. The killer disease? Still a fiction. The drug? It could become a reality thanks to a new study by Rice University bioengineers. view more (2008-11-11)
Oxygen triggered the evolution of complex life forms
Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier than was thought, and in parallel with the availability of oxygen as an energy source. In the largest study to date that does not focus on vertebrates,... view more... (2004-01-22)
Survival of the fittest: even cancer cells follow the laws of evolution
Scientists from The Institute of Advanced Studies at Princeton and the University of California discovered that the underlying process in tumor formation is the same as for life itself-evolution. view more (2008-08-04)
KGI professor contributes new insights on 'jumping genes'
Keck Graduate Institute (KGI) today announced that Dr. Animesh Ray, KGI professor and director of KGI's PhD program, has published a paper in the international online journal PLoS ONE that sheds new light on the evolution of moveable genetic elements, or "jumping genes." view more (2007-10-09)
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)
Molecular evolution of influenza A viruses circulated in Fujian Province, China
Fujian Center for Disease Control & Prevention, China, reported the molecular evolution of influenza A (H3N2) viruses in Fujian Province, south of China during the period 1996 - 2004 and demonstrated some key codons responsible for antigenic drift. The study is reported in Issue 51 (April, 2008) of the Science in China Series C: Life Science... view more... (2008-04-01)
Genetic differences between yeasts greater than those between humans and chimpanzees
The mapping of the entire yeast genome in 1996 marked the beginning of a revolution in biological and medical research. The human genome was mapped in 2001, and by now the number of characterised species is approaching 1000, most of which are bacteria. view more (2009-02-13)
UCI scientists reconstruct migration of avian flu virus
UC Irvine researchers have combined genetic and geographic data of the H5N1 avian flu virus to reconstruct its history over the past decade. They found that multiple strains of the virus originated in the Chinese province of Guangdong, and they identified many of the migration routes through which the strains spread regionally and internationally. view more (2007-03-06)
Competition between species curbs selfishness?
Animals are in constant competition over procreative resources. The interests of the individual and the population are not necessarily one and the same; aggressive insects may fare well in the mating competition, but eventually the proliferation of aggressive genes will weaken the procreative efficiency of the species. view more (2004-12-20)
