More than 350 former NFL players were studied on average 29 years after their playing careers ended. Retirees who experienced concussion symptoms during their playing careers were found to perform worse on a battery of cognitive tests. When comparing the retired players to more than 5,000 men who did not play football, cognitive performance was generally worse for former players, with older players performing worse.

Changes in our REM sleep patterns could potentially be used to diagnose the severity of epilepsy, a new study has suggested. Researchers showed that astrocytes -- star-shaped glial cells that control the local ionic and metabotropic environment of the brain -- exhibit an acid response with REM sleep in mice. They theorize that the acid response could be the underlying drive for specific information processing and generating plasticity during sleep.

Helium -- essential for many medical and industrial processes -- is in critically short supply worldwide. Production is also associated with significant carbon emissions, contributing to climate change. This study provides a new concept in gas field formation to explain why, in rare places, helium accumulates naturally in high concentrations just beneath the Earth's surface. The findings could help locate new reservoirs of carbon-free helium -- and potentially also hydrogen.

Researchers have identified a new mutation that leads to the cardiac disease arrhythmogenic cardiomyopathy (ACM). They assessed the effect of this mutation on heart muscle cells and obtained new insights into the underlying mechanism that causes the disease. The results of this study could contribute to the development of new treatments for ACM.
