Two new studies published last week shed some light on the purpose of so-called 'junk' DNA - vast stretches of mammalian genomes that do not contain any genes, or serve any other obvious purpose. US researchers have showed that wiping out two huge chunks of the mouse genome appears to make...
Sperm contribute paternal DNA when they fertilise an egg - but they also deliver some messenger RNA (mRNA), US researchers say. The unexpected finding means that sperm could play a greater role in early development than previously thought, say the scientists, who reported their results in the journal Nature. The research...
A new database of over 21,000 human genes has been released by an international team of scientists. The new resource, details of which are published in the free journal Public Library of Science Biology, should prove invaluable in the search for genes involved in disease, says project leader Takashi Gojobori...
A team of researchers based at universities in Detroit, US, and Leeds in the UK, have identified the genetic pattern of healthy sperm. They believe the discovery could be a major step forward in our understanding of male infertility and perhaps lead to the development of new male contraceptives. Male...
