Global COVID-19 registry finds strokes associated with COVID-19 are more severe, have worse outcomes and higher mortality

Patients with COVID-19 who have an acute ischemic stroke (AIS) experience more severe strokes, have worse functional outcomes and are more likely to die of stroke than AIS patients who do not have COVID-19. The wide range of complications associated with COVID-19 likely explain the worse outcomes.

The spin state story: Observation of the quantum spin liquid state in novel material

The quantum spin liquid (QSL) state is an exotic state of matter where the spin of electrons, which generally exhibits order at low temperatures, remains disordered. Now, scientists have developed a new material where a two-dimensional QSL state can be experimentally observed, advancing our knowledge of spin behavior, and getting us closer to next-generation...

Changes in the immune system can promote healthy aging

As we age, the immune system gradually becomes impaired. One aspect of this impairment is chronic inflammation in the elderly, which means that the immune system is constantly active and sends out inflammatory substances. Such chronic inflammation is associated with multiple age-related diseases including arthritis and Alzheimer's disease, and impaired...
