A new study finds black patients are more likely to die after their heart bypass surgery if they're at a hospital where some care teams see mostly white patients and others see mostly black patients. On the other hand, mortality rates are comparable between black and white patients after heart bypass surgery when the teams of health care providers at their hospitals all care for patients of all races.

Exploring extreme environments can put significant operational challenges on the engineering systems we depend upon to safely explore and at times operate within.

Researchers at Argonne National Laboratory, the University of Chicago and scientific organizations in Japan, Korea and Hungary have established an invaluable resource for those looking to discover new quantum systems.

Scientists from the University of Bristol's Quantum Engineering Technology Labs (QETLabs) have developed an algorithm that provides valuable insights into the physics underlying quantum systems - paving the way for significant advances in quantum computation and sensing, and potentially turning a new page in scientific investigation.

Though legislative reform is necessary to combat the growing burden of student loan debt in the U.S. on a grand scale, individual borrowers can take steps to repay their loans with as low long-term costs as possible. A new mathematical model develops a strategy for minimizing the overall cost of repaying student loans.
