Looking different 'helps animals to survive'
In the animal kingdom, everything is not as it seems. Individuals of the same species can look very different from each other - what biologists term 'polymorphism.' view more (2009-07-24)
New tool promises more accurate antimalarial drug dosing
Scientists at LSTM have developed a tool to support the development of appropriate age-based dosing regimens for malaria drugs. view more (2009-10-30)
Study Finds Gender Differences In Renal And Other Genes
Many common diseases exhibit gender bias and gender differences have been observed in the development of high blood pressure (hypertension) and heart (cardiovascular) disease. view more (2007-08-09)
New way to help diagnose dementia
A new way of interpreting 3D images of the brain has opened up the possibility of doctors being able to distinguish between Alzheimer’s disease and other degenerative brain diseases. Doctors need to be able to diagnose the correct disease accurately and as early as possible to implement the most appropriate treatment. The work is being... view more... (2000-08-01)
Testosterone turns male juncos into blustery hunks -- and bad dads
The ability to ramp up testosterone production appears to drive male dark-eyed juncos to find and win mates, but it comes with an evolutionary cost. Big fluctuations in testosterone may also cause males to lose interest in parenting their own young, scientists have learned. view more (2007-10-16)
Researchers lift a corner of the veil of depression
About 1 in 10 Europeans has to contend with some form of depression during his or her life. But how people become depressed is still largely a mystery. view more (2006-03-16)
Gene variation may elevate risk of liver tumor in patients with cirrhosis
A particular gene variation appears to significantly increase the risk that individuals with cirrhosis of the liver will go on to develop hepatocellular carcinoma (HCC), a liver tumor that is the third leading cause of cancer death. view more (2008-01-02)
Scientists Take Early Steps Toward Mapping Epigenetic Variability
The study of eipigenetic variability in cells and tissues could someday help diagnose diseases more precisely and provide more targeted treatments for chronic ailments. view more (2009-08-17)
Study breaks ground in revealing how neurons generate movement
When the eye tracks a bird's flight across the sky, the visual experience is normally smooth, without interruption. But underlying this behavior is a complex coordination of neurons that has remained mysterious to scientists. view more (2008-04-25)
Growing crops to cope with climate change
Scientists at the UK's leading plant science centre have uncovered a gene that could help to develop new varieties of crop that will be able to cope with the changing world climate. view more (2006-01-20)
UCLA study finds genetic link between misery and death
In ongoing work to identify how genes interact with social environments to impact human health, UCLA researchers have discovered what they describe as a biochemical link between misery and death. view more (2010-02-25)
What Can Be Found Out By Pulse
Simple and quick method of variation pulsometry allows to evaluate the state of the organism during mass examinations, and in some cases, the researchers believe, is able to replace electroencephalography monitoring. view more (2005-05-20)
Genetic Heterogeneity of Icelanders
Research undertaken by Professor Einar 'rnason at the University of Iceland, Reykjavik and published in the January 2003 issue of Annals of Human Genetics highlights the inaccuracy of claims that Icelanders are a 'genetically homogenous' population. Professor 'rnason explains in his article: "Recently, statements have been made about a... view more... (2003-02-07)
Variants of 'umami' taste receptor contribute to our individualized flavor worlds
Using a combination of sensory, genetic, and in vitro approaches, researchers from the Monell Center confirm that the T1R1-T1R3 taste receptor plays a role in human umami (amino acid) taste. view more (2009-07-09)
New research proves single origin of humans in Africa
New research published in the journal Nature (19 July) has proved the single origin of humans theory by combining studies of global genetic variations in humans with skull measurements across the world. view more (2007-07-19)
Insights into anemia control in dialysis patients
Anemia is one of the most frequent complications of hemodialysis, and its correction is an important factor in restoring a tolerable quality of life to dialysis-dependent patients. view more (2007-07-12)
Study finds connections between genetics, brain activity and preference
A team of researchers from Massachusetts General Hospital (MGH) has used brain imaging, genetics and experimental psychology techniques to identify a connection between brain reward circuitry, a behavioral measurement of preference and a gene variant that appears to influence both. view more (2008-08-07)
New biomarkers could help doctors spot Alzheimer's and other neurodegenerative diseases
Neurodegenerative diseases like Alzheimer's and Parkinson's in their early stages can be difficult for physicians to spot, and many diagnoses are incorrect. view more (2006-08-14)
Breast cancer risk varies significantly among BRCA1 and BRCA2 carriers
There is a broad variation in the risk of developing breast cancer among people who carry the BRCA1 and BRCA2 gene mutation, according to a study in the January 9/16 issue of JAMA. view more (2008-01-09)
Arctic Sediments Show That 20th Century Warming Is Unlike Natural Variation
The possibility that climate change might simply be a natural variation like others that have occurred throughout geologic time is dimming, according to evidence in a Proceedings of the National Academy of Sciences paper published today. view more (2009-10-26)
