The spacing effect in memory is well-known in neuroscience, where spaced repetition of stimuli leads to stronger, longer-lasting memory formation in the brain. The new findings show that the same principle applies not just to brain cells, but to many other human cell types.

More work needs to be done to create viable human embryos, but the method might someday be used in IVF to help infertile people and male couples.

Spaceflight makes certain human stem cells age faster, a study finds, furthering the understanding of the possible effects of space exploration on the human body.

"This discovery shows that the body has a built-in backup plan. GLP-1 is simply a much more powerful signal for beta cells than glucagon,” Dr Campbell said. “The ability to switch from glucagon to GLP-1 in times of metabolic stress may be a critical way the body maintains blood sugar control,” he explained.

Scientists have developed functional eggs from ordinary human skin cells, a proof of concept that could open up new ways to treat infertility.

NASA's AVATAR study will send Emulate organ chips containing human cells on the Artemis II mission to study how deep space affects health.

Using a ChatGPT-like AI model, scientists have created a new map of the mouse brain that captures previously uncharted areas of the organ in unprecedented detail.
