What are ideal blood sugar levels for preventing repeat strokes, heart attacks?
Blood sugar control has always been important for people with diabetes when it comes to preventing a stroke. But a new study finds for people with diabetes who have a stroke, there may be an ideal target blood sugar range to lower the risk of different types of vascular diseases like a stroke...

Correlated electrons ‘tango’ in a perovskite oxide at the extreme quantum limit

Correlated electrons ‘tango’ in a perovskite oxide at the extreme quantum limit
Scientists have found a rare quantum material in which electrons move in coordinated ways, essentially 'dancing.' Straining the material creates an electronic band structure that sets the stage for exotic, more tightly correlated behavior -- akin to tangoing -- among Dirac electrons, which...
