We analyzed cerebral tissues of the anterior cingulate cortex and superior temporal gyrus of schizophrenia cases and controls by using micro-CT. Mean curvatures of the capillary vessels showed a significant correlation to the mean curvatures of neurites, while the mean capillary diameter was almost constant, independent of the cases. The curved capillaries with a constant diameter should occupy a...
A new species of large prehistoric croc that roamed southeast Queensland's waterways millions of years ago has been documented by University of Queensland researchers.
Honeybees bring back more than just nectar from their floral feasts and these microbes may help them survive turbulent times.
A new imaging technique has the potential to detect neurological disorders--such as Alzheimer's disease--at their earliest stages, enabling physicians to diagnose and treat patients more quickly. Termed super-resolution, the imaging methodology combines position emission tomography (PET) with an external motion tracking device to create highly detailed images of the brain. This research was...
An observation of an insect exoskeleton on a potted plant may lead to the identification of a new species of cicada.
E. coli adapt to survive sudden starvation. Biologists from Washington University in St. Louis and Stanford showed that when E. coli cells lack nutrients, the cytoplasm becomes more dense as its volume decreases, probably because of water loss. At the same time, the periplasm increases in volume as the inner membrane pulls away from the outer membrane.
Research carried out by academics at NUI Galway and clinicians at University Hospital Galway Diabetes Centre, involving more than 4,500 patients in the west of Ireland, suggests that, despite careful medical management, a relatively high proportion of people with diabetes in Ireland are developing chronic kidney disease over time and are at risk of kidney failure and other complications of poor...
