Casting a mould for political leaders
Acknowledging the pressure for greater transparency and understanding of political roles, psychologists have pinpointed the skills of effective political leaders and have produced a national framework for government departments to use in the selection and development of their politicians. view more (2005-01-07)
Gene evolution process discovered
One of the mechanisms governing how our physical features and behavioural traits have evolved over centuries has been discovered by researchers at the University of Leeds. view more (2009-06-16)
Human vision inadequate for research on bird vision
The most attractive male birds attract more females and as a result are most successful in terms of reproduction. This is the starting point of many studies looking for factors that influence sexual selection in birds. view more (2008-05-13)
Injecting science into doctor recruitment
Health authorities typically use old-fashioned selection techniques to recruit doctors. The traditional CV and interview practices currently employed are unsophisticated and lack scientific rigor. Doctor recruitment requires a more systematic and thorough assessment of the skills critical to their job. view more (2005-01-07)
Prevention of scrapie by means of selection in animals
To help prevent scrapie in sheep by means of animal selection is the aim of a project, throughout the whole of Spain, by a research group from the Agrarian Production Department of the Public University of Navarre together with other institutions such as the National Institute for Agrarian and Animal Feed Research & Technology (INIA), the... view more...

CT and MRI accurate for pre-transplant evaluation of patients with cirrhosis
CT and MRI are highly accurate at determining which patients would be optimal candidates for liver transplantation, says a recent study. view more (2007-05-07)
Researchers witness natural selection at work in dramatic comeback of male butterflies
An international team of researchers has documented a remarkable example of natural selection in a tropical butterfly species that fought back - genetically speaking - against a highly invasive, male-killing bacteria. view more (2007-07-13)
Study shows male homosexuality can be explained through a specific model of Darwinian evolution
Reporting in this week's PLoS ONE, an Italian research team, consisting of Andrea Camperio Ciani and Giovanni Zanzotto at the University of Padova and Paolo Cermelli at the University of Torino, found that the evolutionary origin and maintenance of male homosexuality in human populations could be explained by a model based around the idea of... view more...

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)
New discovery: Molecular variation in one gene affects the growth of natural populations
For the first time, ecologists have been able to show that molecular variation in one gene may affect the growth of a population in its natural habitat. view more (2006-04-26)
Why some people are more attractive than others
Researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different? view more (2007-03-28)
Study proposes new theory of how viruses may contribute to cancer
A new study suggests that viruses may contribute to cancer by causing excessive death to normal cells while promoting the growth of surviving cells with cancerous traits. view more (2007-10-24)
Convergent evolution of molecules in electric fish
Having a set of extra genes gave fish on separate continents the ability to evolve electric organs, report researchers from The University of Texas at Austin. view more (2006-03-06)
DNA of ancient lost barley could help modern crops cope with water stress
Researchers at the University of Warwick have recovered significant DNA information from a lost form of ancient barley that triumphed for over 3000 years seeing off: 5 changes in civilisation, water shortages and a much more popular form of barley that produces more grains. view more (2009-07-21)
Old mystery solved, revealing origin of regulatory T cells that 'police' and protect the body
More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years. view more (2005-10-13)
Remote sheep population resists genetic drift
A whimsical attempt to establish a herd of mouflon for sport hunting on a remote island in the Indian Ocean 50 years ago has inadvertently created a laboratory for genetic researchers and led to a surprising discovery. view more (2007-03-12)
Did the North Atlantic fisheries collapse due to fisheries-induced evolution?
The Atlantic cod has, for many centuries, sustained major fisheries on both sides of the Atlantic. However, the North American fisheries have now largely collapsed. view more (2009-05-27)
UCSD Study Shows Junk DNA Has Evolutionary Importance
Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD. view more (2005-10-20)
A new explanation for evolutionary changes in genetic sex-determination systems
In animals with separate sexes, embryos commit to becoming male or female at an early stage. Often this key decision is made by sex determination genes on the sex chromosomes. The genes involved in sexual development have changed remarkably little during evolution. In contrast, the sex determination genes and the sex chromosomes themselves are... view more... (2007-10-22)
Duke study examines evolutionary consequences of bluebird aggression
In findings that may offer insight into how evolution operates, a Duke University evolutionary ecologist reported evidence that aggressive male western bluebirds out-compete less aggressive males for preferred breeding territories. view more (2006-04-13)
