Age is more than a number — In barn owls, it reveals how susceptible one is to climate change
Fluctuations in weather and the environment affect survival and reproduction of animals. But are all individuals within a population equally susceptible? Theory on the evolution in age-structured populations suggests not - those life stages that are more important for overall fitness should be less susceptible to environmental variation than other... view more...

Planned home birth with registered midwife as safe as hospital birth
The risk of infant death following planned home birth attended by a registered midwife does not differ from that of a planned hospital birth. view more (2009-08-31)
If you want more babies, find a man with a deep voice
Men who have lower-pitched voices have more children than do men with high-pitched voices, researchers have found. And their study suggests that for reproductive-minded women, mate selection favours men with low-pitched voices. view more (2007-09-25)
New model suggests role of low vitamin D in cancer development
In studying the preventive effects of vitamin D, researchers at the Moores Cancer Center at the University of California, San Diego, have proposed a new model of cancer development that hinges on a loss of cancer cells' ability to stick together. view more (2009-05-22)
Media invitation: Insects matter more than ever
Insects are a rapid reaction force. They evolve, whether following Darwin's ideas on natural selection or in response to changing circumstances, and the integral role they play in our world is changing too. Top scientists from across the globe are coming to Reading, Berkshire in July to share their research on how these changes affect our own... view more... (2003-07-09)
Genetic differences in clover make one type toxic
That clover necklace you make for your child could well be a ring of poison. That's because some clovers have evolved genes that help the plant produce cyanide - to protect itself against little herbivores, such as snails, slugs and voles, that eat clover. view more (2007-10-02)
Finland and China sign new funding agreement
Research cooperation since the early 1980s The Academy of Finland and the National Natural Science Foundation of China have signed an agreement concerning the funding of joint projects among centres of excellence in research. The closing date for the current round of applications is 11 January 2002. Funding is available for joint projects in two... view more... (2001-12-19)
Why didn't Darwin discover Mendel's laws?
Mendel solved the logic of inheritance in his monastery garden with no more technology than Darwin had in his garden at Down House. view more (2009-02-27)
Polluted ground water poured into a model
Dutch researcher Phil Ham has developed mathematical models to calculate the natural degradation capacity of polluted groundwater. view more (2006-04-19)
Study of huge numbers of genetic mutations point to oxidative stress as underlying cause
A study that tracked genetic mutations through the human equivalent of about 5,000 years has demonstrated for the first time that oxidative DNA damage is a primary cause of the process of mutation - the fuel for evolution but also a leading cause of aging, cancer and other diseases. view more (2009-09-08)
One more step in assisted chlidbirth
The Assisted Childbirth Units at Quir'³n San Sebasti'¡n and Quir'³n Bilbao have achieved the first pregnancy in the Basque Autonomous Community and Navarre by means of the technique known as Preimplantational Genetic Diagnostic (PGD), the novelty of which lies in optimum selection of embryons by means of their genetic study prior to their... view more...

World's smallest snake found in Barbados
The world's smallest species of snake, with adults averaging just under four inches in length, has been identified on the Caribbean island of Barbados. The species -- which is as thin as a spaghetti noodle and small enough to rest comfortably on a U.S. quarter --was discovered by Blair Hedges, an evolutionary biologist at Penn State. view more (2008-08-04)
New pathways for autoimmune treatment identified
A rare genetic defect that can trigger a host of diseases from type 1 diabetes to alopecia has helped explain the imbalance of immune regulator and killer cells in autoimmune disease. view more (2006-05-30)
Fish vision discovery makes waves in natural selection
Emory University researchers have identified the first fish known to have switched from ultraviolet vision to violet vision, or the ability to see blue light. The discovery is also the first example of an animal deleting a molecule to change its visual spectrum. view more (2009-10-19)
Chronic HIV-1 infection frequently fails to protect against superinfection
Natural HIV-1 infection does not always elicit a protective immune response, according to a new study published November 16 in PLoS Pathogens. view more (2007-11-16)
Melanoma treatment options 1 step closer
A targeted chemotherapy for the treatment of skin cancer is one step closer, after a team of University of Alberta researchers successfully synthesized a natural substance that shows exceptional potential to specifically treat this often fatal disease. view more (2009-10-21)
Opposites attract -- how genetics influences humans to choose their mates
New light has been thrown on how humans choose their partners, a scientist will tell the annual conference of the European Society of Human Genetics today. view more (2009-05-26)
Changing fashions govern mating success in lark buntings, study finds
A study of how female lark buntings choose their mates, published this week in Science, adds a surprising new twist to the evolutionary theory of sexual selection. view more (2008-01-25)
Choosing the wood using artificial vision
Amongst the TR+D projects financed by the Basque Government INTEK programme, the IT Department at CIDEMCO, in conjunction with the CEIT Centre of Technology, the CVC company, and furniture manufacturers BIOK, XEY and DANONA, have finished the final phase of the development of an artificial vision system for the formulation of colorants for the... view more...

Size does matter when choosing a mate
The difference in size between males and females of the same species is all down to the battle for a mate, according to a study of shorebirds published by British scientists today (August 9 2004). The findings, published in the Proceedings of the National Academy of Sciences, are the first explanation for a rule identified over forty years ago by... view more... (2004-08-09)
