Carl Woese, a biophysicist and evolutionary microbiologist whose discovery 35 years ago of a “third domain” of life in the vast realm of micro-organisms altered scientific understanding of evolution, died on Sunday at his home in Urbana, Ill. He was 84.
His death was announced by the Universi... Read More
An 'exhausted' army of immune cells may not be able to fight off infection, but if its soldiers fight too hard they risk damaging the very body they are meant to be protecting, suggests new research from the University of Cambridge. Read More
ANYONE who walks in the woods will be familiar with witches’ brooms (pictured). Many trees sport these bushy tumours, which have a variety of causes. An important one is a group of bacteria called phytoplasma that are, in turn, carried from plant to plant by sap-sucking insects such as leafhoppe... Read More
Boy, it's a good time to be a dark chocolate lover.
We've noted before the growing evidence that a daily dose of the bitter bean may help reduce blood pressure. There also seems to be a link between a regular chocolate habit and lower body weight.
Now scientists are offering an explanation... Read More
A bacterial protein in common house dust may worsen allergic responses to indoor allergens, according to research conducted by the National Institutes of Health and Duke University. The finding is the first to document the presence of the protein flagellin in house dust, bolstering the link betw... Read More
Are you willing to take a close look at yourself for science?
A really, really close look?
A team of scientists in the Bay Area is inviting citizen scientists to join them in a quest to create the largest database of human microbiomes in the world.
The human microbiome is the ecosystem ... Read More
In a healthy adult human body, most internal organs such as the brain, spleen, liver, and heart are devoid of microorganisms because the immune system keeps them in check. After human host death, however, the immune system falters and microorganisms proliferate throughout the body beginning in ... Read More
