60 years after pioneering survey, Wisconsin prairies are changing rapidly

A recent study found that human influence has accelerated the rate of species change in Wisconsin prairies, with some sites having fewer than 18% of original species and more than 60% non-native species. Controlled fires are being shown to be beneficial for restoring native habitat.

Some hospice patients experience care transitions near life's end

A study found that hospice patients experience multiple care transitions near the end of life, with more than half going to hospitals. These transitions are often associated with younger or non-white patients, those with multiple chronic conditions, or in-patient hospice care. The number of transitions varies widely by state.

Topological insulators: Magnetism is not causing loss of conductivity

Researchers have shown that magnetism does not cause topological insulators to lose their conductivity. Instead, they found a band gap that is significantly larger than predicted by theory and involves a different causal mechanism. The study suggests that scattering processes may be responsible for opening the band gap.
