Ophthalmologists Prove Existence of CLANs

A team of ophthalmologists at the University of Liverpool has become the first in the world to image geodesic structures – called CLANs – inside the human body.

Professor Ian Grierson and his colleagues have found that the shape of each CLAN is similar to the design of the framework forming the roofs over the Eden Project and the courtyard at the British Museum.

CLANs is an acronym for Cross-linked Action Networks. They are formed from the components which maintain the str

Scientists sequence DNA of woolly mammoth

Experts in ancient DNA from McMaster University (Canada) have teamed up with genome researchers from Penn State University (USA) for the investigation of permafrost bone samples from Siberia. The project also involved paleontologists from the American Museum of Natural History (USA) and researchers from Russia, the United Kingdom, France, and Germany. The researchers’ report on the first genomic sequences from a woolly mammoth will be published on 22 December 2005 by the journal Science on

New microchip technology for medical imaging biomarkers of disease

A collaboration between scientists at UCLA, Caltech, Stanford, Siemens and Fluidigm have developed a new technology using integrated microfluidics chips for simplifying, lowering the cost and diversifying the types of molecules used to image the biology of disease with the medical imaging technology, Positron Emission Tomography (PET). These molecules are used with PET to diagnostically search throughout the body to look for (image) the molecular errors of disease and to guide the development of

New Methods Offer Insight into Regulatory DNA

Through the Human Genome Project, the HapMap Project and other efforts, we are beginning to identify genes that are modified in some diseases. More difficult to measure and identify are the regulatory regions in DNA – the ‘managers’ of genes – that control gene activity and might be important in causing disease.

Today, a team led by the Wellcome Trust Sanger Institute, together with colleagues in the USA and Switzerland, provide a measure of just how important regulatory region var

A quality dog/owner relationship no help to storm-phobic canines

Having a sympathetic owner did not lower the stress reaction of dogs that become anxious or fearful during noisy thunderstorms but living in a multi-dog household did, a Penn State study has found.

The study is among the first to measure, non-invasively, the production of a specific stress hormone produced by both the dog and its owner in response to stress in their home. The technique offers a new tool to assess animal welfare in a wide variety of non-laboratory settings, in

Chromosome four contains genes that affect drinking behaviors in smokers

Alcoholism is a complex behavior that draws from both environmental and genetic factors. Researchers have found in a sample of smokers chromosomal regions that affect patterns of drinking behavior. These findings support results from previous research that link alcohol metabolism genes on chromosomes two and four with alcohol consumption. Researchers firmly believe that alcoholism is a complex behavior that draws from both environmental and genetic factors. A rece
