Predicting frailty, disability and death

Movement is a part of daily life that most people rarely spend time contemplating, but changes in such movements can portend disease and decline. Watch-like devices known as actimetry sensors, which can be worn on the wrist or ankle, allow researchers to collect information about a subject’s motor activity. In a study led by investigators … Read more

Detection dogs and DNA on the trail of endangered lizards

Detection dogs trained to sniff out the scat of an endangered lizard in California’s San Joaquin Valley, combined with genetic species identification, could represent a new noninvasive sampling technique for lizard conservation worldwide. That is according to a study published today from the University of California, Davis, in partnership with the nonprofit Working Dogs for … Read more

Tiny swimming donuts deliver the goods

Bacteria and other swimming microorganisms evolved to thrive in challenging environments, and researchers struggle to mimic their unique abilities for biomedical technologies, but fabrication challenges created a manufacturing bottleneck. Microscopic, 3D-printed, tori – donuts ­­- coated with nickel and platinum may bridge the gap between biological and synthetic swimmers, according to an international team of … Read more

Classic energy theory fails to explain coral distribution across depth

Coral species richness at different depths is unrelated to energy availability, according to a new study analysing diversity across an Australasian reef. Research from James Cook University, Lancaster University, the University of Copenhagen and Queensland University of Technology, published in Biology Letters, reveals neither energy availability alone, nor in combination with other local factors, accounts for … Read more

Life expectancy mapped for people with mental disorders

People with mental disorders have a life expectancy up to a decade shorter than the general population, University of Queensland researchers discovered in a joint international study. Professor John McGrath from UQ’s Queensland Brain Institute and Dr Oleguer Plana-Ripoll from Denmark’s Aarhus University led the study, which found that on average mental disorders shortened life … Read more
