Star technology aids DNA analysis
University of Leicester astronomers and biologists have patented a new way of analysing DNA from gene-chips, which may be used in laboratories and hospitals to diagnose diseases from a single drop of blood and compare gene expression in different samples. The pioneering technique uses an instrument developed at the European Space Agency's... view more... (2003-11-03)
Methane found in desert soils bolsters theories that life could exist on Mars
Evidence of methane-producing organisms can be found in inhospitable soil environments much like those found on the surface of Mars. view more (2005-11-01)
Microscopes at microscopic size
Traditionally if scientists wanted to look at something small they would put a sample under a microscope but now researchers have managed to shrink the microscope itself to the size of a single human cell. An interdisciplinary research team, funded by the Biotechnology and Biological Science Research Council (BBSRC) and the Engineering and... view more... (2005-04-07)
Testosterone, territoriality and the ‘home advantage’ in football
The `home advantage` is well known in football. The majority of teams in all divisions score more goals and win more games at home than away. Factors such as crowd support, referee bias, and familiarity with a venue, have been used to explain home advantage. New research presented today, Saturday 16 March, at The British Psychological Society... view more... (2002-02-27)
Early detection of Alzheimer's disease a possibility
Research investigating concentrations of magnetite, a magnetic form of iron, in Alzheimer's disease tissue has produced preliminary results that suggest the possibility of developing a technique to detect Alzheimer's disease before clinical symptoms appear. The research*, published in Biology Letters, an online supplement to the Royal Society's... view more... (2003-04-07)
Crime scene or nature reserve?
A method used by forensic experts to collect evidence from crime scenes could soon be taken up by biologists studying animals in the wild. An article in BMC Ecology this week describes how DNA from animal blood and tissue samples can be stored on record cards made from specialist filter paper and used in experiments at a later date.... view more...

New therapeutic targets for neurodegenerative diseases
The focus of work in the Neurosciences Department's Neurobiology Laboratory at the University of the Basque Country's Faculty of Medicine and Odontology is the investigation of the molecular and cellular bases of neurodegenerative illnesses - those that affect the brain and the spinal cord. view more (2007-05-11)
Study of malaria parasites reveals new parasitic states
A team led by scientists at MIT and Harvard University and supported in part by the National Institute of Allergy and Infectious Diseases, a component of the National Institutes of Health, collected blood samples from 43 P. falciparum-infected malaria patients in Senegal who were suffering from a range of malaria symptoms. view more (2007-11-29)
Raman spectroscopy to undergo a UV transformation - New technique could help rapid detection of infecting organisms in hospitals and prove authenticity of foods such
Researchers at the University of Wales, Aberystwyth (UWA) are about to put ultra-violet Raman spectroscopy through its paces as a new technique for studying biological materials. Dr Roy Goodacre and colleagues in the Institute of Biological Sciences have been awarded a grant worth £306,291 by the Engineering and Physical Sciences Research... view more... (2002-03-01)
The Prestige oil spill caused changes in the cell structure of mussels
The oil spill from the Prestige petroleum oil tanker in 2002 caused serious damage to the ecosystems in the Bay of Biscay. A PhD thesis at the University of the Basque Country (UPV/EHU) has studied the consequences of this spill for the mussels inhabiting this northern coast of the Iberian peninsula. view more (2009-03-25)
Gardens in space
A model of a system for growing plants to plan biological experiments in space has just left the company of ROVSING, in Ballerup near Copenhagen, on its way to ESA's European Space Research and Technology Centre (ESTEC) in the Netherlands. The full name of this experiment reference model is European Modular Cultivation System Experiment... view more... (2002-05-13)
Free radical scavenging is defective in periodontal (tooth loosening) disease
The capacity to mop up harmful oxygen free radicals seems to be reduced in people with periodontal disease, finds research in Molecular Pathology. Periodontal disease affects between 10 and 15% of people worldwide. A leading cause of tooth loss, it develops as a result of bacterial infection from a build-up of the sticky, colourless bacterial... view more... (2002-11-22)
Urgent need for more research into prevalence of CJD
The first estimate of the number of people who are at increased risk of vCJD, but who have not developed symptoms, is published in this week`s BMJ. Researchers studied specimens from appendicectomies and tonsillectomies carried out between 1995 and 1999. They also examined samples removed at autopsy or during surgery from... view more...

Targeting the protein AEG1 impairs human liver cancer growth in mice
Hepatocellular carcinoma (HCC) is a highly aggressive form of liver cancer and one of the 5 most common cancers worldwide. Devanand Sarkar and colleagues, at Virginia Commonwealth University School of Medicine, Richmond, have now identified a gene that is expressed at high levels in human HCC tumor samples and generates a protein important for HCC... view more...

BIOMARKERS IN ADOLESCENTS COULD PROVIDE MEASUREMENT FOR ENVIRONMENTAL POLLUTION (p 1660)
Biological markers in adolescents could be a reliable measure of exposure to environmental pollutants, according to a study in this week's issue of THE LANCET which highlights how increased exposure among adolescents slows sexual development. Human exposure to chemicals is normally monitored by measurement of environmental pollutants externally.... view more... (2001-05-23)
Research leads to healthful strategies for re-setting the body's clock
Everyone is equipped with a biological clock, a region in the brain the size of a corn kernel, which dictates our sleep-wake cycles, and plays a major role in our physical and mental health. view more (2006-03-23)
Hair samples may be more accurate measure of exposure to second hand smoke
Strands of hair accurately measure second hand tobacco smoke exposure, finds research in the Journal of Epidemiology and Community Health. And they may be more effective than currently used methods, suggest the authors. view more (2001-12-17)
Neural development protein disproved as marker for schizophrenia
The results of a study published today in the open access journal BMC Psychiatry contradict previous findings and show that Oct-6, a protein involved in neurodevelopment, is normally expressed in the adult brain and cannot be used to identify patients with schizophrenia. view more (2005-10-24)
Researchers announce results of study on genetic variation in Parkinson's disease
Researchers at the National Institutes of Health (NIH) have completed one of the first large-scale studies of the role of common genetic variation in Parkinson's disease (PD). view more (2006-09-28)
No place for life to hide from Mars Express
Of all missions sent to Mars only one, the Viking 26 years ago, has dared to search for life. Its only conclusive result was that finding proof of extraterrestrial life proved to be much harder than expected. Second attempts never followed. Until now. ESA`s Mars Express, the next mission to the Red Planet and the first European one, has an... view more... (2002-09-03)
