Dementia imposes an annual societal cost of more than €221 billion across 30 high-income European countries, with families and unpaid informal carers carrying much of the burden, according to a new study published in the Journal of Alzheimer’s Disease.

Marine scientists at UC Santa Barbara have found that disturbances to giant kelp forests have a major influence on their net primary productivity (NPP) — an indicator of an ecosystem’s health and its ability to support its community — even more so than the availability of the resources it needs to grow. Taking data from decades of monthly measurements in the kelp forests of the campus’s National Science Foundation-supported Santa Barbara Coastal Long Term Ecological Research (SBC LTER) site, the researchers uncovered the direct, indirect and fascinating effects of disturbance on one of the world’s most productive ecosystems.

New research suggests that myotonia—the delayed relaxation of muscles that causes stiffness—may be more than a symptom of myotonic dystrophy type 1 (DM1). In animal models, eliminating myotonia improved muscle strength and muscle health.
