Researchers from the University of Chicago have identified a gene defect that causes the development of leukemia in children with Down syndrome. The discovery, scheduled for Advance Online Publication on Nature Geneticss website on 12 August, could speed diagnosis and provide a new target for therapy.
Children with Down syndrome are 10 to 20 times as likely as unaffected children to develop leukemia. They most commonly develop a type known as acute megakaryoblastic leukemia (AMKL), wh
Using photon emissions from individual molecules of silver, researchers at the Georgia Institute of Technology have created what may be the worlds smallest electroluminescent light source.
Believed to be the first demonstration of electroluminescence from individual molecules, the work could lead to new types of nanometer-scale optical interconnects, high-resolution optical microscopy, nanometer-scale lithography and other applications that require very small light sources. And becaus
Study links body fat, cancer risk
Hispanic women have been known to run a lower risk of developing breast cancer than most other women, but their breast cancer rates are climbing—and increasing obesity is one factor that might be to blame.
The weight that Hispanic women gain during adulthood and their body fat may put them at greater risk for breast cancer both before and after menopause, according to researchers from the Keck School of Medicine of USC, the University of New
The technological centre Robotiker from Zamudio (Basque Country) has developed a system of artificial sight to separate metals that come with copper, in order to obtain high purity copper.
To recover copper from old cables it is not something new. However, the recycled copper is not pure, because it is mixed with other metals, such as lead, aluminium and tin. It is quite complicated to separate copper from those components by using mechanical, physical and other methods. Nevertheless it is
Study hypothesizes that adolescent steroid exposure may permanently alter the production of the feel good receptor
“With more than one in ten boys admitting to using steroids, muscle- and strength-enhancing drug use among teenagers has caused considerable concern among parents and researchers over the past decade, but until now, the longer-term physiological and neurological effects of its use on the developing brain have not been fully examined. Now, new research from Nor
Findings from a Research Letter in this week’s issue of THE LANCET provide support for the idea that children who grow up on farms have fewer allergies because they are exposed to more microbes than other children.
Farmers’ children are known to be less prone to allergies than children who do not grow up on farms, but the exact reason is not known. Previous work has shown a circumstantial link between exposure to bacteria and reduced allergy; Dr Roger Lauener and colleagues from Zurich Unive
