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.
'Snorkel' genes, boon for rice output in flooded areas of IndiaAugust 31st, 2009 WASHINGTON - Researchers have identified a couple of genes that could script a new story of rice production in India and Bangladesh and Asia in general. The two genes allow deep-water rice varieties to elongate their stems to be above the rising water level, especially during floods, instead of drowning in it.
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.
Are genes behind musicians' pitch recognition skill?July 3rd, 2009 WASHINGTON - Practice makes perfect in music, but fresh evidence thrown up by research shows that for aspiring musicians, genes may also influence the outcome. Perfect pitch, also known as absolute pitch, is the rare ability to recognise and name musical notes without any reference pitch for comparison, detecting, for instance, A before middle C.
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.
Genes that influence the onset of menstruation identifiedMay 30th, 2009 WASHINGTON - An international team of researchers have identified genes that influence the start of menstruation, a milestone of female reproductive health that has lifelong influences on overall health. The team includes two scientists at the Institute for Aging Research of Hebrew SeniorLife.
How oxidative stress may help extend lifespanMay 29th, 2009 WASHINGTON - Scientists at the University of California, San Diego claim to have identified a mechanism of oxidative stress that prevents cellular damage. "We may drink pomegranate juice to protect our bodies from so-called 'free radicals' or look at restricting calorie intake to extend our lifespan," said Dr Trey Ideker, chief of the Division of Genetics in the Department of Medicine at UC San Diego's School of Medicine and professor of bioengineering at the Jacobs School of Engineering.
Genes switching on menstruation identifiedMay 18th, 2009 WASHINGTON - In findings that could improve understanding of human growth, researchers have identified two genes that switch on the process of menstruation among women. The finding could help scientists address short stature and increased body weight, as both are connected to early onset of menstruation.
How cocaine-linked genes enhance behavioural effects of addictionMay 14th, 2009 WASHINGTON - Scientists from Mount Sinai School of Medicine have shed light on how cocaine-linked genes enhance behavioural effects of addiction - a find that will lead to new strategies for battling the habit. The research team led by Dr Eric J.
The biological basis for the 8-hour work-shiftApril 24th, 2009 WASHINGTON - Your usual nine to five office shift has a biological reason behind it, and now scientists have found that some genes in the body are switched on once every 12 or 8 hours, which in turn keeps us actively involved in the work, according to a new study. The findings by researchers at the University of Pennsylvania School of Medicine and the Salk Institute for Biological Studies indicated that shorter cycles of the circadian rhythm are also biologically encoded.
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.
