A new study used pollen data to evaluate the second plague pandemic's mortality at a regional scale across Europe. Results showed that the impacts of the Black Death varied substantially from region to region and demonstrated the importance of cross-disciplinary approaches for understanding past -- and present -- pandemics.

When a person tries to access a memory, their brain quickly sifts through everything stored in it to find the relevant information. But as we age, many of us have difficulty retrieving memories. Researchers propose an explanation for why this might be happening: the brains of older adults allocate more space to accumulated knowledge and have more material to navigate when attempting to access memories. While this wealth of prior knowledge can make memory retrieval challenging, the researchers say it has its upsides -- this life experience can aid with creativity and decision-making.

Researchers have developed a dome-shaped device, which fits over a person's head and can be worn during a brain scan, that boosts MRI performance, creating crisper images that can be captured at twice the normal speed. Eventually, the magnetic metamaterial has the potential to be used in conjunction with cheaper low-field MRI machines to make the technology more widely available, particularly in the developing world.
