Mars Sample Return: bridging robotic and human exploration
The first robotic mission to return samples to Earth from Mars took a further step toward realisation with the recent publication of a mission design report by the iMARS Working Group. The report defines key elements of the future internationally-funded mission involving the cooperation of ESA, NASA and other national agencies. view more (2008-07-23)
Better measurements reveal seasonal changes in sulfur
Researchers from the University of Maryland (UMD) and the National Institute of Standards and Technology (NIST) have developed a new and improved technique for the simultaneous measurement of sulfur isotopic ratios and concentrations of atmospheric sulfate using snow samples from Greenland and Kyrgyzstan. view more (2005-10-10)
Biology could be the root of bother
Better understanding of the biological and cognitive bases of disruptive behaviour in children will help psychologists determine which types of treatments are most likely to be effective. view more (2005-03-21)
Hormone irregularities linked to chronic migraine
Hormonal irregularities may explain why migraine becomes chronic, shows research in the Journal of Neurology Neurosurgery and Psychiatry. Around 3 per cent of the population are chronic migraineurs, suffering pounding headaches for around 15 days a month. Hourly blood samples were taken from 17 chronic migraine sufferers, three of whom were men.... view more... (2001-11-23)
New method identifies rat poison in humans
Researchers at the Norwegian Institute of Public Health (NIPH) have developed a method to identify bromadiolone poisoning in humans. Bromadiolone is a rat poison that can be purchased freely in shops. A number of cases have been reported internationally where people have been poisoned, with a mortality rate of 20 percent. view more (2008-05-28)
New Toxic Sampling Kit Measures Contaminated Land
A University of Surrey spin-out company, Cybersense Biosystems Ltd, has developed a portable toxicity screening device. The ROTAS system can be literally wheeled on to a brown field site and carry out field-based screening of contaminated soils and waters and results can be read within minutes. It is especially relevant with the Government's... view more... (2004-07-22)
Automimmune response more common in people with severe coronary heart disease
The development of severe coronary artery disease may be part of a systemic autoimmune response, suggests research in the Annals of the Rheumatic Diseases. view more (2002-01-15)
Pitt Researchers Zero In on Ozone With Fluorescent Solution That Detects Harmful Molecule in the Air and Body
Researchers at the University of Pittsburgh have developed a fluorescent substance that glows bright green when exposed to even minute amounts of ozone in the air and in biological samples such as human lung cells. view more (2009-06-23)
NIST develops rapid method for judging nanotube purity
Researchers at the National Institute of Standards and Technology (NIST) have developed a sensitive new method for rapidly assessing the quality of carbon nanotubes. view more (2007-02-02)
Molecules in glass houses
Trapping biological molecules such as proteins and enzymes or even whole cells in rigid structures make them easier to use for a whole range of industrial and medical applications. But combining fragile biological molecules with tough materials is difficult to do without damaging the molecules and destroying their biological activity. As well as... view more... (2001-08-01)
UNIVERSITY SPIDER MAN CHARTS REGION`S SPECIES
A University of Plymouth lecturer has helped to compile a two-volume atlas detailing the biology, habitat and conservation of over 600 species of British spider. Peter Smithers of the Department of Biological Sciences has spent the last 20 years gathering information in Devon and Cornwall as part of the nationwide project, which was initiated in... view more...

Prototype terahertz imager promises biochem advances
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new imaging system that detects naturally occurring terahertz radiation with unprecedented sensitivity and resolution. view more (2008-04-16)
Oral rinses used for tracking HPV-positive head and neck cancers holds promise for cancer screening
A study published in the journal Clinical Cancer Research, a journal of the American Association for Cancer Research, validates a non-invasive screening method with future potential for detection of human papillomavirus (HPV)-positive head and neck cancers. view more (2008-10-31)
New imaging method lets scientists 'see' cell molecules more clearly
Scientists have always wanted to take a closer look at biological systems and materials. From the magnifying glass to the electron microscope, they have developed ever-increasingly sophisticated imaging devices. view more (2009-01-21)
Patient leaflets may not be effective in the real world
Leaflets used to promote informed choice in women using maternity services in the UK are not effective in everyday practice, say researchers from Sheffield University in this week's BMJ. Thirteen maternity units in Wales participated in the study. Units either used leaflets to promote informed choice (intervention units) or continued with usual... view more... (2002-03-13)
Free music, sampled
Free products samples give consumers the opportunity to try before they buy. This tried and tested marketing model works well for products as diverse as shampoo and washing powder, instant coffee and bubble gum. view more (2009-06-02)
University of Pittsburgh discovers genetic 'shut down' trigger in healthy immune cells
A fundamental genetic mechanism that shuts down an important gene in healthy immune system cells has been discovered that could one day lead to new therapies against infections, leukemia and other cancers. view more (2007-05-10)
New nanosensor uses quantum dots to detect DNA
Using tiny semiconductor crystals, biological probes and a laser, Johns Hopkins University engineers have developed a new method of finding specific sequences of DNA by making them light up beneath a microscope. view more (2005-12-06)
Viruses may play a role in lung cancer development
Papers presented at the 1st European Lung Cancer Conference, jointly organized by the European Society for Medical Oncology (ESMO) and the International Association for the Study of Lung Cancer (IASLC) in Geneva, Switzerland highlight emerging evidence that common viruses may contribute to the development of lung cancer. view more (2008-04-25)
New study replicates association between genetic variation and antidepressant treatment response
Pharmacogenetics, the study of genetic variation that influences an individual's response to drugs, is an important and growing focus in all of medical research, including psychiatry. view more (2008-07-16)
