Organized phone-based psychotherapy for depression found cost-effectiveOctober 6th, 2009 WASHINGTON - An organised phone-based cognitive behavioural psychotherapy soon after starting on antidepressant medication can help treat depression easily, the effects of which is believed to persist for at least two years after first session, say researchers. Organized phone therapy for depression has also been found cost-effective with only modest rises.
Some species are unable to adapt to climate change due to their genesSeptember 4th, 2009 WASHINGTON - A new study has determined that species living in restricted environments such as the tropics may lack adequate variation in their genes and be unable to adapt to climate change. Adaptation is a physiological or behavioural change that makes an organism better suited to its environment, and more likely to survive and reproduce.
90 percent of US paper money contains traces of cocaineAugust 17th, 2009 WASHINGTON - In a new analysis, scientists have found traces of cocaine in up to 90 percent of paper money in the United States, particularly in large cities such as Baltimore, Boston, and Detroit. This is the largest, most comprehensive analysis to date of cocaine contamination in banknotes.
Sessions cracks up Sotomayor hearing with 'crack cocaine' misstatementJuly 16th, 2009 Sessions' 'crack cocaine' comment cracks up crowdWASHINGTON — Alabama Sen. Jeff Sessions' comment on crack cocaine cracked up the crowd.
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.
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.
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.
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.
Novel compound can treat addiction by shutting drug-related memoriesApril 24th, 2009 WASHINGTON - Scientists have found that a novel compound could treat addiction by warding off memories linked with the time of prior drug use. Despite being abstinent for long periods of time, many addicts remain vulnerable to their own memories of drug use in the past.
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.
Stress of early life social isolation may enhance juvenile response to cocaineApril 17th, 2009 WASHINGTON - Experiments on rats conducted by researchers at the University of Puerto Rico have shown that isolation during early development alters the brain sensitivity to cocaine. Researchers Natasha Lugo-Escobar, Nicole Carreras, and Annabell C.
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.
