Learn how to 'speak' from songbird genesSeptember 30th, 2009 WASHINGTON - The ability to manipulate songbird genes may yield secrets of vocal learning and how nerve cells (neurons) are replaced. For the first time, researchers have devised a way to alter the genes of the zebra finch, one of a handful of social animals that learn to "speak" by imitating their fellows.
Drug-free cannabis plant comes closer to realitySeptember 16th, 2009 WASHINGTON - Scientists have come closer to engineering drug-free cannabis plant after identifying genes that produce psychoactive substance in marijuana. University of Minnesota researchers have identified genes producing tetrahydrocannabinol (THC), the psychoactive substance in marijuana, which could lead to new and better drugs for pain, nausea and other conditions.
What makes us uniquely humanSeptember 2nd, 2009 WASHINGTON - In a remarkable piece of detective work, scientists working at Trinity College Dublin have discovered three genes that are unique to humans. In the study published online in Genome Research, boffins have made a crucial discovery of genes that have evolved in humans after branching off from other primates.
Scientists isolate genes that imbue us with uniquely human traitsSeptember 2nd, 2009 WASHINGTON - Humans and chimpanzees are genetically very similar yet clearly distinct in many ways. Scientists have isolated genes that evolved in humans after branching off from other primates, making us uniquely human.
Variations in dogs coat types result from variations in just 3 genesAugust 27th, 2009 Three genes combine for 7 coat types in dogsWASHINGTON — From short to shaggy, nearly all the differences in dogs' coat types result from variations in just three genes, according to researchers studying how genes work together. "What's important for human health is the way we found the genes involved in dog coats and figured out how they work together, rather than the genes themselves," said Dr.
Male sex chromosome on way to extinctionJuly 17th, 2009 WASHINGTON - The sex chromosome that only males carry is deteriorating and could disappear within a few million years. A pair of Penn State University (PSU) scientists discovered that the male Y chromosome evolved at a much more rapid pace than X chromosome, which both males and females carry.
Male sex chromosome facing extinction due to rapid evolutionJuly 17th, 2009 WASHINGTON - A new research has revealed that the sex chromosome that only males carry is deteriorating and could disappear within a few million years. Scientists at Penn State University (PSU) found that the male Y chromosome evolved at a much more rapid pace than X chromosome, which both males and females carry.
Rock-solid self-confidence is in the genesJuly 2nd, 2009 LONDON - If you always attributed a rock-solid self-confidence to upbringing and other environmental factors then better think again, for an unshakeable self belief is in the genes, according to a new study. The psychiatrists behind the study say that the ability to perform under pressure is more than a state of mind, and that some people are just born with it.
Genes that affect aggression in fruit flies identifiedJune 11th, 2009 WASHINGTON - Scientists have identified a set of genes that affect aggression in the fruit fly Drosophila melanogaster. By studying male flies from a large panel of lines, which each carry a mutation in a single gene but are otherwise genetically identical, researchers identified particularly angry and particularly placid insects, uncovering 59 mutations in 57 genes that affect aggressive behaviour.
Different genes cause loss of body parts in similar fishJune 5th, 2009 WASHINGTON - A new research has shown that different genes can cause loss of body parts in similar fish, by comparing how 2 species of sticklebacks lost pelvises and body armor. The research, funded by the National Science Foundation (NSF)'s Divisions of Environmental Biology and Integrative Organismal Systems, shows that when two species of stickleback fish evolved and lost their pelvises and body armor, different genes in each species caused the changes.
Why 'super-recognisers' never forget a face?May 20th, 2009 WASHINGTON - Some people assert that they can never forget a face, even many years later, a claim which has now been substantiated by psychologists. The new study suggests that skill in facial recognition might vary widely among humans.
The best musicians all have the perfect pitchMay 20th, 2009 WASHINGTON - Mozart, Tchaikovsky, Sinatra and Hendrix - these and many others of the world's most famous musicians have had the 'perfect' or 'absolute' pitch. The ability, defined as recognising the pitch of a musical note without having to compare it to any reference note, is quite rare in the US and Europe, where only about one person in 10,000 seems to have it.
Genes that protect against aging identifiedApril 21st, 2009 WASHINGTON - University of Liverpool researchers have developed a novel method to help scientists identify genes that can help protect the body during the ageing process. The team developed a method of analysing genes in multiple ageing tissue types in both animals and humans.
Scientists identify genes that determine right warfarin doseMarch 21st, 2009 WASHINGTON - Researchers at Uppsala University, together with colleagues at Karolinska Institute and Sanger Institute, have identified three genes that would help determine the optimal dose of blood-thinning drug warfarin. The team led by Mia Wadelius have come across three genes VKORC1, CYP2C9, and CYP4F2 that would help determine adequate warfarin dosage.
Genes linked to spinal disc degeneration identifiedMarch 14th, 2009 WASHINGTON - Researchers from University of Alberta have identified certain genes responsible for spinal disc degeneration. Michele Crites-Battie and Tapio Videman, in the Faculty of Rehabilitation Medicine, have discovered eight genes linked to lumbar disc degeneration.
