New assessment warns area the size of the USA will become too hot during extreme heat events for even healthy young humans to maintain a safe body temperature if we hit 2 degrees Celsuis above preindustrial levels. For those aged over 60, the same 2 degree rise would see more than a third of the planet's land mass cross this critical 'overheating' threshold.

Researchers have used mathematical analysis tools to study the effect of classical music on a fetal heartbeat and identify patterns in heart rate variability. They recruited 36 pregnant women and played two classical pieces for their fetuses. By attaching external heart rate monitors, the researchers could measure the fetal heart rate response to both songs, and by employing nonlinear recurrence quantification analysis, they could identify changes in heart rate variability during and after the music was played. They found evidence music can calm fetal heart rates, potentially providing developmental benefits.
