A lack of funding to labs is likely to mean an early death for thousands of mice used in scientific and medical research. The loss of specialty mice, many of which have genes that can cause them to develop versions of human diseases, is especially troubling to scientists — and expensive.

The Clinical Center at the National Institutes of Health in Maryland is often the last resort for patients who have mysterious, rare or terminal diseases. Patients sometimes call it the "House of Hope." But the government shutdown may mean that prospective patients will be turned away.
