UAB researchers detail underlying mechanism leading to age-associated osteoporosis
A major health problem in older people is age-associated osteoporosis -- the thinning of bone and the loss of bone density that increases the risk of fractures. Often this is accompanied by an increase in fat cells in the bone marrow.
Study identifies two genes involved in invasive group A Streptococcus infections
Group A Streptococcus bacteria cause a variety of illnesses that range from mild nuisances like strep throat to life-threatening conditions including pneumonia, toxic shock syndrome and the flesh-eating disease formally known as necrotizing fasciitis.
UCI study improves understanding of brain's navigational system
The ability to successfully navigate in the environment is essential both for animals searching for food or escaping predators, as well as for human urban dwellers. It is something we take for granted, but under the hood, it is supported by still incompletely understood brain networks that continuously calculate our position in the environment.
Research provides new insights on the border between conscious and unconscious perception
Whether or not we consciously perceive the stimuli projected onto our retina is decided in our brain. A recent study by the University of Bonn shows how some signals dissipate along the processing path to conscious perception.
Study presents new method for tracing history of β-cells
Tracing the history of individual cells in the developing organism can reveal functional differences among seemingly uniform cells. This knowledge is important for defining the characteristics of highly regenerative cells in order to target them for cellular therapies, as well as to prevent the formation of unfit cells, which compromise the overall health of the organism.
Genome-wide study reveals how transposons get prepared for jumping
The genome of a typical organism consists of many genes that are stringed like beads. This alignment has been surprisingly stable even over very long evolutionary periods. In addition to these genes, there are also many mobile elements, referred to as parasitic, that are spread across the whole genome and aggregated into different families according to their relatedness.
