Bonobos and chimps offer clues to how our early ancestors had sex for social purposes

A recent study comparing the sexual behavior of bonobos and chimpanzees during stressful periods has provided insights into humans' own behavioral origins. Both species utilized sex to manage social tension, with bonobos engaging in 'make-up sex' after conflicts and chimpanzees using sex in various ways to ease tensions.

Amphibians bounce-back from Earth’s greatest mass extinction

Researchers found that ancient frog relatives thrived after the Permian-Triassic mass extinction due to their generalist feeding ecology and ability to feed on a wide variety of prey. They were able to survive and even flourish in freshwater habitats, which provided them with stable food resources amidst the turbulent Triassic ecosystem.

Sleep health may impact mobility for women with chronic conditions

A study published in Sleep Epidemiology found that poor sleep health predicted a decline in mobility over eight years following a chronic health diagnosis. Women with diabetes, osteoarthritis, or multiple sclerosis who also had signs of obstructive sleep apnea were more likely to experience future mobility problems.

How the brain distinguishes between pain and itch

Researchers discovered distinct neuronal populations in the ACC process pain and itch information separately, with stimulus-specific neurons receiving differentiated synaptic inputs from the mediodorsal thalamus. Suppressing these neurons reduced corresponding sensations without affecting the other.
