Quick, simple test developed to identify patients who will not respond to the painkiller tramadol
French researchers have found a way to identify quickly the five-ten percent of patients in whom the commonly used painkiller, tramadol, does not work effectively.

Scientists reveal structure of bacterial chainmail
An international team of scientists, funded in the UK by the Biotechnology and Biological Sciences Research Council, has uncovered the structure of the protective protein coat which surrounds many bacteria like a miniature suit of armor.

Researchers watch tiny living machines self-assemble
Enabling bioengineers to design new molecular machines for nanotechnology applications is one of the possible outcomes of a study by University of Montreal researchers that was published in Nature Structural and Molecular Biology today.

Researchers develop a 'time bomb' to fight cardiovascular disease
Atherosclerosis, resulting in a narrowing of the arteries and the development of cardiovascular disease, is the leading cause of death worldwide.

Researchers found 4 gene loci predisposing people to the most common subtype of migraine
An international research group has identified four new gene loci predisposing people to the most common subtype of migraine, migraine without aura.

Decoding DNA finds breast tumor signatures that predict treatment response
Decoding the DNA of patients with advanced breast cancer has allowed scientists to identify distinct cancer

Scripps Research scientists develop new tools to unveil mystery of the 'glycome'
Scientists at the Scripps Research Institute have developed chemical compounds that can make key modifications to common sugar molecules (

Sleep deprivation may lead to higher anxiety levels, fMRI scans show
New research shows that sleep loss exaggerates anticipation impulses, leading to anxiety issues, particularly among people already highly anxious.

MRI scans show how sleep loss affects the ability to choose proper foods
fMRI scans reveal how sleep deprivation impairs higher-order regions in the human brain where food choices are made - not the deeper brain structures reacting to basic desire.

Positive results from first human clinical trials of a first-generation artificial pancreas system is significant step forward for millions with type 1 diabetes
Results from the first feasibility study of an advanced first-generation artificial pancreas system indicated that the Hypoglycemia-Hyperglycemia Minimizer (HHM) System was able to automatically predict a rise and fall in blood glucose and correspondingly increase and/or decrease insulin delivery safely.

'Bad' dieting increases cardiovascular disease risk
A 25 year study, published in BioMed Central's open access journal Nutrition Journal, is the first to show that a regional and national dietary intervention to reduce fat intake, decreased cholesterol levels, but a switch to the popular low carbohydrate diet was paralleled by in an increase in cholesterol levels.

Studies challenge established views development of children raised by gay or lesbian parents
Despite considerable research showing that children of same-sex parents fare just as well as children with heterosexual parents, two papers - a review of existing studies and a new study - published today in Elsevier's Social Science Research, find insufficient data to draw any definitive conclusions.

Undersea volcano gave off signals before eruption in 2011
A team of scientists that last year created waves by correctly forecasting the 2011 eruption of Axial Seamount years in advance now says that the undersea volcano located some 250 miles off the Oregon coast gave off clear signals hours before its impending eruption.

New insight into placental growth and healthy pregnancy
Scientists at the Babraham Institute have gained a new understanding of how the growth of the placenta is regulated before birth, which has important implications for a healthy pregnancy.

Brain scans show specific neuronal response to junk food when sleep-restricted
The sight of unhealthy food during a period of sleep restriction activated reward centers in the brain less active than with adequate sleep, a new study using fMRI scans shows.

Aspirin before heart surgery reduces the risk of post-operative acute kidney failure
Aspirin taken for five days before a heart operation can halve the numbers of patients developing post-operative acute kidney failure, according to research to be presented at the European Anaesthesiology Congress in Paris on Sunday.
