Study finds gene related to brain development and function plays causal role in schizophrenia
According to a new study conducted by researchers at Mount Sinai School of Medicine, variations of a gene related to brain development and function-OLIG2-may play a causal role in the development of schizophrenia, a hereditary psychiatric disorder with no known biological cause. view more (2006-08-16)
The muskox suffered a loss of genetic diversity at the Pleistocene/Holocene transition
The tundra muskox, one of the few large northern mammals to have survived to the present day, saw its genetic diversity decrease greatly at the end of the Pleistocene period, around 10,000 years ago. view more (2005-10-06)
Technique to arrest urinary incontinence
The University Hospital of Navarra is to carry out clinical trials for urinary incontinence using the intraurethral injection of myoblasts (adult stem cells obtained by means of a biopsy of the patient). view more (2006-10-04)
microRNA-mediated metabolism
In the February 15th issue of G&D, Drs. Aurelio Teleman and Stephen Cohen (EMBL) assign one of the first biological functions to an animal microRNA: the microRNA miR-278 regulates energy homeostasis in Drosophila. view more (2006-02-15)
New study examines the validity of epo testing
Recombinant human erythropoietin (rHuEpo) is a genetically engineered hormone sometimes misused by high-performance athletes such as cyclists and marathon runners to boost their endurance. view more (2008-06-26)
Baby bathwater contains fragrance allergens
A group of chemists from the University of Santiago de Compostela (USC) has developed a method to quantify the fragrance allergens found in baby bathwater. view more (2009-07-17)
1 sample examined by 1,000 pathologists -- how and why?
This week, more than eight hundred pathologists from around Europe and the world will take part in a first of its kind, large-scale virtual microscopy slide seminar on the web. view more (2007-09-06)
Cancer stem cells similar to normal stem cells can thwart anti-cancer agents
Current cancer therapies often succeed at initially eliminating the bulk of the disease, including all rapidly proliferating cells, but are eventually thwarted because they cannot eliminate a small reservoir of multiple-drug-resistant tumor cells, called cancer stem cells, which ultimately become the source of disease recurrence and eventual... view more...

Threatened bumble bee populations studied in Southampton
Work is underway by researchers at the University of Southampton's School of Biological Sciences to help halt the decline in bumble bees. view more (2004-09-14)
Bio-imaging mass spectrometry techniques reveal molecular details about complex systems
Understanding biology at the systems level is difficult, especially when studying complex specimens like tissue slices or communities of organisms in a biofilm. Scientists must be able to identify, quantify and locate the molecules present in the samples. view more (2008-09-26)
Emergency tests focus on lab radioactivity analyses
Working under severe time pressure, government laboratories can analyze radioactive samples fairly quickly - in a matter of hours - but with variable accuracy, and sometimes relaxed quality control procedures, according to a published analysis of two federally organized tests of the labs' emergency preparedness. view more (2006-10-02)
Mobile Lab Expands Capacity of Animal Disease Diagnostics
In the event of a disease outbreak, a rapid, massive response by health officials is critical - even if the patients are animals. view more (2006-02-24)
Lupus gene finding prompts call for more DNA samples
Wellcome Trust researchers have identified a key gene involved in the disease Lupus, which affects around 50,000 people in the UK, mostly women. view more (2007-12-03)
Pictures hardly subject to leaching during cleaning
If picture restorers are careful when using solvents, very few organic molecules are likely to be leached away from the paint layer. Serious leaching does however occur when paint samples are immersed in solvents. These are some of the results of a study carried out at the National Gallery of Art in Washington DC as part of NWO’s Molart... view more... (2001-05-30)
New approach to detect autism earlier
A new way of understanding autistic disorders, incorporating both psychological and biological factors, could lead to the conditions being picked up earlier, research from UNSW has found. view more (2008-01-25)
Scientists solve mystery of the 'unicorn' whale
Once the subject of mythical accounts of magical power, the helix-shaped tusk of the narwhal, or "unicorn" whale has proved to be an extraordinary sensory organ. view more (2005-12-23)
Ancient organisms discovered in Canadian gold mine
Scientists have suspected that the three known domains of life -- eukaryotes, bacteria, and archaea -- branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task. view more (2007-08-21)
Liking sweets makes sense for kids
As any parent knows, children love sweet-tasting foods. Now, new research from the University of Washington and the Monell Center indicates that this heightened liking for sweetness has a biological basis and is related to children's high growth rate. view more (2009-03-19)
Epstein-Barr virus may be associated with multiple sclerosis
Young adults with high levels of antibodies against the Epstein-Barr virus, the virus that most often causes mononucleosis, may be more likely to develop multiple sclerosis 15 to 20 years later. view more (2006-04-11)
Iron and biological production in the high-latitude North Atlantic
Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions. view more (2009-07-08)
