It's been long thought that when blood transfusions are needed, it may be best to use the freshest blood, but McMaster University researchers have led a large international study proving that it is not so.
New research from Newcastle University, UK, in collaboration with the Federal University of Rio de Janeiro, investigated the way the human brain folds and how this 'cortical folding' changes with age.
The superbug MRSA uses decoys to evade a last-resort antibiotic, reveals new research. The findings, from scientists at Imperial College London, suggest potential new ways of tackling the bacteria, such as interfering with the decoys.
Analysis of mammal teeth can reveal local environmental conditions. A new study employs data collected from Kenyan national parks over the past 60 years, combined with traits of the teeth of herbivorous mammals. The results were recently published in the journal PNAS.
The bacterium Pseudomonas aeruginosa is a life-threatening pathogen in hospitals. About ten percent of all nosocomial infections, in particular pneumonia, are caused by this pathogen. Researchers from the University of Basel's Biozentrum, have now discovered that calcium induces the switch from acute to chronic infection. In Nature Microbiology the researchers have also reported why antibiotics are less effective in fighting the pathogen in its chronic state.
A protein found in the blood of pregnant women could be used to develop tests to determine the health of their babies and aid decisions on early elective deliveries, according to an early study led by Queen Mary University of London.
Ninety years ago, a world record-breaking 750-legged millipede was discovered in California. Now, scientists have found a closely related species in Sequoia National Park to partner the former one in its genus. The new species may possess 'only' 414 legs, yet, it has a similar complement of bizarre anatomical features, including a body armed with 200 poison glands, silk-secreting hairs, and 4 penises. The study is published in the open-access journal ZooKeys.
One of the most detailed genomic studies of any ecosystem to date has revealed an underground world of stunning microbial diversity, and added dozens of new branches to the tree of life. The bacterial bonanza comes from scientists who reconstructed the genomes of more than 2,500 microbes from sediment and groundwater samples collected at an aquifer in Colorado.
Charcot-Marie-Tooth disease is an inherited disorder that leads to a gradual loss of motor neurons and, eventually, paralysis. There is no treatment. Now, scientists at Washington University School of Medicine in St. Louis and Stanford University report that they have designed small compounds that may correct the molecular dysfunction that leads to Charcot-Marie-Tooth. The team designed the compounds based on a new understanding of the 3-D structure of a key protein associated with the disease.
An atom-by-atom picture of a marine shell's first formation shows that magnesium and sodium ions may control how shells grow under different environmental conditions.
