Calico Cats Inspire Research Into X Chromosome Inactivation
2014-02-19 04:31:40

April Flowers for redOrbit.com - Your Universe Online Calico cats are renowned and beloved for their funky orange and black patchwork or "tortoiseshell" fur. Cat Breeds Encyclopedia reports that these felines — considered to be good luck in several countries — are 90 percent female, suggesting that the color pattern is related to the gender of the animal. New research from the University of California San Francisco (UCSF), has further linked this unique color pattern to X chromosome...

Why Do Women And Men Differ In Height?

University of Helsinki Researchers from the University of Helsinki analyzed thoroughly the commonly occurring genetic variation in chromosome X, one of the two sex-determining chromosomes, in almost 25,000 Northern European individuals with diverse health-related information available. The aim of the study was to find genetic factors that could explain individual differences in several traits, including BMI, height, blood pressure and lipid levels. In addition, the researchers also...

New insights into how the cells in our bodies divide could improve our knowledge of a condition linked to cancer, a study suggests. Errors in the cell division process – which allows us to grow and stay healthy – can lead to a genetic disorder called aneuploidy, which is also associated with birth defects and infertility. Researchers at the University of Edinburgh have pinpointed the key role played by a protein in ensuring that cells separate correctly. During cell division,...

Y Chromosome Not Going To Disappear

Brett Smith for redOrbit.com - Your Universe Online Finally, some good news for men, as a new study in PLOS Genetics has found that the human race may not be losing the Y chromosome after all. Some popular theories have posited that the male sex chromosome is destined to diminish and disappear. "The Y chromosome has lost 90 percent of the genes it once shared with the X chromosome, and some scientists have speculated that the Y chromosome will disappear in less than 5 million years,"...

Plants can reproduce in a multitude of different ways, unlike humans and animals. Scientists at the University of Veterinary Medicine Vienna have been working on developing new varieties of chamomile that can be cultivated as a medicinal plant. The researchers have been trying to identify varieties that will bloom longer and make its cultivation easier. Their methods and results have recently been published in the scientific press. Chamomile is a medicinal plant used mainly in the...

A new view of our chromosomes reveals a complex picture Chromosomes – the 46 tightly-wrapped packages of genetic material in our cells – are iconically depicted as X-shaped formations. However, those neat X’s only appear when a cell is about to divide and the entire contents of its genome duplicated. Until now researchers have not been able to get a good picture of the way that our DNA – some two meters of strands all told – is neatly bundled into the nucleus while enabling...

Two Y Genes Can Replace Entire Y Chromosome For Assisted Reproduction In Mice
2013-11-21 15:33:20

University of Hawaii at Manoa The Y chromosome is a symbol of maleness, present only in males and encoding genes important for male reproduction. But live mouse offspring can be generated with assisted reproduction using germ cells from males with the Y chromosome contribution limited to only two genes: the testis determinant factor Sry and the spermatogonial proliferation factor Eif2s3y. "Does this mean that the Y chromosome (or most of it) is no longer needed? Yes, given our current...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
