Cells in our bodies produce RNA based on genetic information stored in DNA, and RNA serves as a blueprint for making proteins. Researchers at KAIST have discovered a new phenomenon: Removing "circular ...

A bandage-like microneedle patch can noninvasively collect immune cells and signals from the skin within minutes to hours.

A study published in the journal Nature showed that the thymus, a small organ in the chest known for training the immune system in childhood, is also important for long-term health and lifespan.

Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, ...

Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

Sickle cell disease is often thought of solely as a blood disorder, but new research from the Wood Neuro Research Group ...

Errors in chromosome segregation cause more than 80% of early human embryos to contain cells with an incorrect number of chromosomes, a phenomenon called aneuploidy. While aneuploid cells are normally ...

Traveling to space can take a toll on the human body, and new research shows it can also speed up the aging of blood and immune cells. Over the 32-45 days the stem cells spent in space, the fitness ...

Scientists recorded 24 hours of the cellular construction process, revealing surprising new details about how plant cell ...

Post-traumatic Stress Disorder (PTSD) isn’t caused by just one faulty switch in the brain; it’s more like a tangled orchestra of genes and cells thrown off-key by trauma. With many genetic players ...

A well-fitted ‘disguise’ allows transplanted mitochondria to slip into cells whose own mitochondria are defective, scientists reported 18 March in Cell 1. Administration of these cloaked mitochondria ...
