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.
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.
Happiness experiment aims to spread laughter across UKJuly 31st, 2009 LONDON - Scientists are planning to cheer up Britons next week with the help of an online psychological experiment. Starting Monday, the experiment will be conducted for five days.
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.
Castor-oil plants genetically altered to produce new bio-lubricantsJune 28th, 2009 WASHINGTON - Scientists of the University of Almeria have genetically altered the castor-oil plant so as to use it as a factory to produce bio lubricants. The scientists identified and provided a series of genes that are responsible of the biosynthesis of lipids that can be used to obtain transgenic castor-oil plants with an acid profile appropriate for the different requirements of bio lubricants.
How our physical features, behavioural traits have evolved over centuriesJune 16th, 2009 WASHINGTON - Researchers at the University of Leeds claim that they have discovered one of the mechanisms governing how physical features and behavioural traits among humans have evolved over centuries. When Charles Darwin proposed that such traits are passed from a parent to their offspring, with natural selection favouring those that give the greatest advantage for survival, the English naturalist did not have a scientific explanation for this process.
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.
Happiness 'can be inherited'May 15th, 2009 WASHINGTON - Our feelings in our lifetime can affect our children, concludes a new study. Dr Alberto Halabe Bucay led the study published in Elsevier's journal Bioscience Hypotheses.
Scientists coax skin cells to behave like muscle cellsMay 6th, 2009 WASHINGTON - Scientists have now shown that skin cells can be coaxed to behave like muscle cells and muscle cells like skin cells. The fickleness of the cells, and the relative ease with which they make the switch, provide a glimpse into the genetic reprogramming that must occur for a cell to become something it's not.
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.
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.
Genes from fireflies shed light show causes of infertilityMarch 28th, 2009 WASHINGTON - Genes from fireflies and jellyfish are virtually shedding light on possible causes of infertility and auto-immune diseases in humans. Auto-immune diseases are those in which something goes wrong with your immune system and it attacks healthy cells and tissues and makes you sick.
Common genes could explain alcohol, nicotine, cocaine addictionsMarch 16th, 2009 WASHINGTON - Researchers may be honing in on specific genes tied to all types of addictions and finding that some of the same genes associated with alcohol dependence are also closely linked with addictions to nicotine, cocaine, opoids, heroin and other substances. Addiction experts at the Universities of Virginia (UV) and Michigan have presented new insights into the significant progress made within the last several years in understanding the genetics of addiction.
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.
