This review article summarizes the structure and stability of all the minichromosomes that Minoru Murata and colleagues at Okayama University have isolated since 2006, and describes their interesting features.
Trillions of bacteria live in the human body, and although there's plenty of evidence that these microbes play a collective role in human health, we know very little about the individual bacterial species. Employing the use of a specially designed glass chip with tiny compartments, researchers provide a way to target and grow specific microbes from the gut - a key step in understanding which bacteria are helpful to human health and which are harmful.
Researchers gained new insight into the role of CCL2, a chemokine known to be involved in the immune response, in the enhancement of stem cell pluripotency. In the study, the researchers replaced basic fibroblast growth factor (bFGF), a critical component of human stem cell culture, with CCL2 and studied its effect.
A movement is under way that will fast-forward the design of new plant traits. It takes inspiration from engineering and the software industry, and is being underpinned in Cambridge and Norwich by an initiative called OpenPlant.
Researchers have developed a technique to control populations of the Australian sheep blowfly - a major livestock pest in Australia and New Zealand - by making female flies dependent upon a common antibiotic to survive.
A collaboration between the National Science Foundation (NSF) and the National Institutes of Health will give NIH-funded researchers training to help them evaluate their scientific discoveries for commercial potential, with the aim of accelerating biomedical innovations into applied health technologies.
The latest version of a bionic pancreas device has been successfully tested in two five-day clinical trials - one in adults, the other in adolescents - that imposed minimal restrictions on patient activities.
Using a type of human stem cell, researchers say they have created a three-dimensional complement of human retinal tissue in the laboratory, which notably includes functioning photoreceptor cells capable of responding to light, the first step in the process of converting it into visual images.
