Dr. Jason Allaire, an assistant professor of psychology at NC State who co-authored the study, explains that study subjects whose average systolic blood pressure was 130 or higher saw a significant decrease in cognitive function when their blood pressure spiked. However, Allaire notes, study subjects whose average blood pressure was low or normal saw no change in their cognitive functioning – even when their blood pressure shot up.
Specifically, Allaire says, the study shows a link between blood pressure spikes in seniors with high blood pressure and a decrease in their inductive reasoning. "Inductive reasoning is important," Allaire says, "because it is essentially the ability to work flexibly with unfamiliar information and find solutions."
Allaire says the findings may indicate that mental stress is partially responsible for the increase in blood pressure – and the corresponding breakdown in cognitive functioning. However, Allaire notes that normal fluctuations in blood pressure likely play a role as well.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
