People of the Veil: New Study Reveals Clues to Origins of the Nomadic Tuaregs

Not many people could survive the harsh conditions of the Sahara Desert.  Yet the Tuareg have lived in the the region for millennia. The Tuareg call themselves the Imazghan, meaning "free people." Today they are known for a distinctive dark blue turban worn by the men, and for their long history as ...

Ancient DNA Analysis Reveals Family Ties in Ruins of Pompeii

On August 20, 79 AD, a series of small tremors and earthquakes began to shake the two ancient Roman cities of Pompeii and Herculaneum.  Lying in the shadow of Mount Vesuvius — about 150 miles south of the Roman capital — the two cities were often hit by tremors and earthquakes, so most residents were ...

Genetic Study Casts Doubt On Inflammatory Marker As Cause of Heart Disease

Study after study has shown that high blood levels of C-reactive protein (CRP), a marker of inflammation, are associated with increased risk of cardiovascular disease. But what hasn't been clear is whether CRP actually causes heart disease, or just indicates the presence of artery-blocking ...

Better Understanding of Colorectal Cancer-Associated SNP Could Guide Treatment

Much to the surprise of many scientists, a lot of the SNPs identified in genomewide association studies have not been in the parts of genes that encode the molecular machinery of a cell. Instead, many SNPs have been found on the edges of genes, in regions of DNA that control when the genes get turned on or ...

Researchers Warn That Drug Development Based On Obesity Genetics Could Deliver More Than Is Bargained For

Not surprisingly, there has been intense interest in the genetics of obesity in recent years.  Obesity is a major health problem, resulting in tens of thousands of premature deaths and billions of dollars in healthcare costs each year in the United States, and it is known from twin and family studies that ...

Curriculum Reform Needed For An Informed Public When It Comes To Genetics, Expert Says

It's not enough to teach genetics, says Michael Dougherty, director of education for the American Society for Human Genetics.  It has to be taught in the right way. "Current teaching practices may be producing a public that is unprepared to participate effectively as medical consumers in a world where ...

Malaria Has Driven Evolution In Humans And Baboons Alike

Malaria, a strong evolutionary pressure in humans, has also shaped the baboon genome, new research says. Each year at least 350 million people around the world are infected by malaria parasites.  More than one million people, mainly young children, succumb to the disease.  But these numbers would be even ...

Researchers Look For Common Themes In Bipolar Disorder Genetics

Genomewide association studies have had some success in finding DNA variants associated with increased risk for bipolar disorder.  But researchers from the MRC Centre for Neuropsychiatric Genetics and Genomics at Cardiff University in England have taken these studies a step further by looking for common ...
