2012-12-14 08:15:46

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the University College London (UCL) recently revealed that they had identified over 200 genes for Crohn´s Disease, a chronic bowel condition. The scientists believe that knowledge about genetic factors of complex diseases will help in understanding patients´ symptoms and providing better treatment. The study looked at the entire human genome, and the findings are featured in a recent edition of The...

The study, published yesterday in the journal Proceedings of the National Academy of Sciences (PNAS), looked at how genes on sex-linked chromosomes are passed down generations and linked to fertility, using the specific example of the W chromosome in female chickens. The results confirm that although these chromosomes have shrunk over millions of years, and have lost many of their original genes, those that remain are extremely important in predicting fertility and are, therefore, unlikely...

The genetics responsible for frequency-specific hearing loss have remained elusive until recently, when genetic loci were found that affected high-frequency hearing. Now, a study published today in the open access journal BMC Genetics reports, for the first time, genetic loci with effects that are limited to specific portions of the hearing frequency map, particularly those that are most affected in aging-related hearing loss. Presbycusis is the loss of hearing for high-pitched sounds that...

Study of simple organisms reveals preference for those who resemble themselves In a dog-eat-dog world of ruthless competition and 'survival of the fittest,' new research from the University of Leicester reveals that individuals are genetically programmed to work together and cooperate with those who most resemble themselves. A tendency for similar individuals to cooperate selectively with one another, even if they are not close relatives, can evolve spontaneously in simple organisms....

TAU breeds population of lab mice with genetic diversity closer to humans With a 95 percent genomic similarity to humans, mice have long been used to learn about the genetic causes of human disease. Once researchers can shine a light on the genetic factors that cause disease in mice, they can start to develop prevention and treatment options to protect the human population. But this process, called genetic mapping, is a long and difficult road, made more challenging by the 5% difference...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
