Epithelial cells grown on a plastic dish are worse at segregating their chromosomes than epithelial cells growing in mice, a new study shows. The results may help explain why chromosomes go awry in cancer.
A microscope lens implanted deep inside a mouse’s brain shows different patterns of neural activity when the mouse interacts with males, females, or other stimuli. Now, researchers have discovered that sexual experience can trigger long-term changes in these brain patterns.
An analysis of the complete genomes of 2,064 people reveals that multiple genetic variations could contribute to autism. The work suggests that scanning whole genomes may one day be useful for clinical diagnostics.
