Nickel isotope may be methane producing microbe biomarker
Nickel, an important trace nutrient for the single cell organisms that produce methane, may be a useful isotopic marker to pinpoint the past origins of these methanogenic microbes, according to Penn State and University of Bristol, UK, researchers. view more (2009-06-23)
Prediction of RNA pseudoknots using heuristic modeling with mapping and sequential folding
An algorithm utilizing structure mapping and thermodynamics is introduced for RNA pseudoknot prediction. The method finds the minimum free energy in the context of the biological folding direction (5' to 3') of RNA sequences. view more (2007-09-19)
Biobanks will provide 'electronic specimens' for medical research
Future medical research will focus increasingly on electronic data, with less need both for laboratory animals and tissue samples. view more (2009-02-12)
NIST, Army researchers pave the way for anthrax spore standards
Researchers from the National Institute of Standards and Technology (NIST) and the U.S. Army Dugway (Utah) Proving Ground have developed reliable methods based on DNA analysis to assess the concentration and viability of anthrax spores after prolonged storage. view more (2008-04-16)
What makes life go at the tropics?
What causes tropical life to thrive: temperature, or sunlight? The answer is not necessarily "both." According to a study published online this week in PNAS Early Edition, the explosion of species at the tropics has much more to do with warmth than with light. view more (2008-05-28)
LSU scientist finds evidence of 'rain-making' bacteria
Brent Christner, LSU professor of biological sciences, in partnership with colleagues in Montana and France, recently found evidence that rain-making bacteria are widely distributed in the atmosphere. view more (2008-02-29)
Postmortem data support link between gene and schizophrenia
We have known for a long time that there is a genetic component to schizophrenia, but nailing down the gene(s) has not been easy. view more (2005-09-13)
'NMR on a chip' features NIST magnetic mini-sensor
A super-sensitive mini-sensor developed at the National Institute of Standards and Technology (NIST) can detect nuclear magnetic resonance (NMR) in tiny samples of fluids flowing through a novel microchip. view more (2008-02-20)
Illuminating Alzheimer's: Research sheds light on creatine's presence in brain
Alzheimer's disease is one of the most hauntingly destructive maladies to wreak havoc on humans. It robs children of parents and spouses of each other-with lifetimes of memories lost forever behind blank stares. view more (2005-12-22)
People are unlikely to withdraw consent for genetic research
People are unlikely to withdraw consent for genetic research even when samples were taken many years ago, research in this week's BMJ suggests. In 1990 1583 randomly selected people in Sweden donated blood to a World Health Organisation project researching cardiovascular disorders and diabetes. Eleven years later, doctors sought their consent for... view more... (2002-09-18)
Psychological effects of biological and chemical weapons may be worse than physical symptoms
The long term psychological implications of a chemical or biological terrorist attack may be more damaging than any acute physical effects, according to researchers from the UK and USA in this week's BMJ. Professor Simon Wessely and colleagues argue that the main purpose of these weapons is to wreak destruction via psychological means - by... view more... (2001-10-17)
DIAGNOSTIC TEST SHOULD LEAD TO BETTER CONTROL
A genetic test targeted at cattle could have a substantial impact in controlling sleeping sickness in east Africa, conclude authors of a fast-track study in this week's issue of THE LANCET. Sleeping sickness caused by Trypanosoma brucei rhodesiense (transmitted by the tsetse fly) is fatal if not treated. Drug treatment can be associated with... view more... (2001-12-12)
Invention gives improved gene technology analysis
A patent for a system that gives more reliable results in gene technology-based diagnostic tests has been granted to researchers at the Norwegian Institute of Public Health (NIPH). view more (2008-04-25)
Bringing Martian samples to Earth -- preparations outlined in journal Astrobiology
A critical component of NASA's Mars exploration program involves bringing planetary samples back to Earth for in-depth analysis, plans for which are detailed in the latest issue of Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. The report is available free online at www.liebertpub.com/ast view more (2008-08-14)
Free drug samples may burden patients' pockets
Following free drug sample receipt, patients who receive these samples have significantly higher out-of-pocket prescription costs than those who don't, according to the first study to look at the out-of-pocket cost associated with free-sample use. view more (2008-03-25)
New study raises questions about the number of people in the UK who could be incubating vCJD
A team of UK scientists found that 3 out of 12,674 stored appendix and tonsil samples showed evidence of the prion protein associated with vCJD, but urge caution about the way these results are interpreted. The research is published this week in The Journal of Pathology. The study aimed to help health policymakers estimate the numbers of people... view more... (2004-05-18)
Study questions assumptions about human sensitivity to biological motion
Humans may not be any more sensitive in detecting biological motion compared with nonbiological motion, concludes a study recently published in Journal of Vision, an online, free-access publication of the Association for Research in Vision and Ophthalmology (ARVO). view more (2007-10-18)
A new approach to prostate cancer detection
On Friday 20 March, US researcher Dr. Chris Beecher from the University of Michigan gave a well attended lecture about sarcosine, an N-methyl derivative of the amino acid glycine, at the 24th Annual EAU Congress in Stockholm, Sweden. view more (2009-03-26)
Unfavourable blood fat levels predict rheumatoid arthritis up to 10 years later
An unfavourable ratio of blood fats could herald the development of the inflammatory joint disease rheumatoid arthritis up to 10 years later, suggests research published ahead of print in the Annals of Rheumatic Diseases. view more (2006-06-05)
Prevention is better than cure
The Institute of Biology is calling on the International Community to strengthen the Biological and Toxins Weapons Convention. In a statement to be presented to the Fifth Review Conference of the Parties to the Biological and Toxins Weapons Convention (BTWC), the Institute warns that the current genomics revolution may be misused unless a... view more...
