Sex-based prenatal brain differences found
Prenatal sex-based biological differences extend to genetic expression in cerebral cortices. The differences in question are probably associated with later divergences in how our brains develop. view more (2009-10-26)
University of Sussex biologists estimate the pace of evolution
Scientists at the University of Sussex have provided the key to resolving a 30-year-old controversy in evolutionary biology: what proportion of the differences between similar species came about as a result of natural selection, and how many are just the result of 'random genetic drift'. In a paper in this week's issue of Nature (28 February),... view more... (2002-02-26)
University of Toronto finds humans and chimps differ at level of gene splicing
Researchers are closer to understanding why humans differ so greatly from chimpanzees in the way they look, behave, think, and fight off disease, despite having genes that are nearly 99% identical. view more (2007-11-15)
Tiny genetic differences have huge consequences: McGill researchers
A study led by McGill University researchers has demonstrated that small differences between individuals at the DNA level can lead to dramatic differences in the way genes produce proteins. view more (2008-01-21)
Ice Ages and rivers may have affected gorilla diversification
Geography and historical climate change may have both played a major role in gorilla evolutionary diversification, according to a new genetic study by Cardiff University and the University of New Orleans. view more (2007-12-11)
Genes may determine success of anti-inflammatory therapy for rheumatoid arthritis
Small genetic differences may explain why the same drug works well in one individual but not in another. These genetic variations could be exploited to develop individually tailored treatment programmes for rheumatoid arthritis, Swedish researchers said today. Speaking at the Press Conference during EULAR 2001, the prestigious annual congress of... view more... (2001-06-14)
Genetic differences influence aging rates in the wild
Long-lived, wild animals harbor genetic differences that influence how quickly they begin to show their age, according to the results of a long-term study reported online on December 13th in Current Biology, a Cell Press publication. view more (2007-12-13)
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)
Claims of sex-related differences in genetic association studies often not properly validated
A review of previous research suggests that prominent claims of sex differences of gene-disease associations are often insufficiently documented and validated. view more (2007-08-22)
Some ethnic groups more susceptible to adverse drug reactions
Some ethnic groups may be more susceptible to adverse drug reactions, finds a study published on bmj.com today. view more (2006-05-05)
'Paper of the Year' winner announced (p 2101)
Results of a search for the most important biomedical research papers of the past year are announced in this week's issue of THE LANCET. The Lancet's 24-member International Advisory Board put forward the nominations-which could be from any source, not just THE LANCET. The winning paper, chosen by the journal's editors, is: Noah A Rosenberg... view more... (2003-12-17)
Genes are of little importance in rheumatoid arthritis
Genes are of little importance in the development of rheumatoid arthritis, finds a study in this week's BMJ. view more (2002-01-30)
Three new species of lemurs identified
Researchers have identified three new species of lemurs, the small, big-eyed primates native to the island of Madagascar. view more (2006-02-23)
A novel method to measure circadian cycles
The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study circadian differences (and thereby hope to rout out the underlying genetic causes), scientists have had to rely on prolonged behavioural observation. view more (2005-09-27)
Can you be born a couch potato?
The key to good health is to be physically active. The key to being active is- to be born that way? view more (2008-07-17)
Mixed couples avoid ethnic and religious confrontations
Church marriages between Catholics and Protestants have only been possible in the Netherlands since 1971. Religious differences have since become less controversial; ethnic differences, by contrast, have become more so. view more (1999-09-16)
Study of twins finds genetic link to fatigue
Unexplained disabling fatigue in childhood is mainly due to genetic inheritance, a study of twins has revealed. view more (2006-09-08)
Is love at first sight real? Geneticists offer tantalizing clues
Leave it to geneticists to answer a question that has perplexed humanity since the dawn of time: does love at first sight truly exist? view more (2009-04-08)
Ethnic differences in response to HIV medicines
Researchers from the University of Massachusetts and the University of Pennsylvania have shown that race/ethnicity is a predictor of plasma lipids in patients with HIV-1 on HAART (highly active antiretroviral therapy). view more (2006-01-24)
UCLA researchers examine human embryonic stem cell genome
Stem cell researchers from UCLA used a high resolution technique to examine the genome, or total DNA content, of a pair of human embryonic stem cell lines and found that while both lines could form neurons, the lines had differences in the numbers of certain genes that could control such things as individual traits and disease susceptibility. view more (2008-03-28)
