Mouse pups recognize their caregiving mother and distinguish her from novel mothers as newborns and remember them after up to 100 days apart, according to a new study in the journal Cell Reports. Laham et al. show that mice form memories of their mother within days after birth and that these memories persist into adulthood. Image credit: Laham et al., doi: 10.1016/j.celrep.2020.108668. Some of the most enduring social connections begin when infants...

This 3D model of a polymer desalination membrane shows water avoiding dense spots in the membrane and slowing flow; red above the membrane shows water under higher pressure and with higher concentrations of salt; the gold, granular, sponge-like structure in the middle shows denser and less-dense areas within the salt-stopping membrane; silver channels show how water flows through; and the blue at the bottom shows water under lower pressure and with lower concentrations of salt.

Differences in brain activity between connected and disconnected states of consciousness studied with positron emission tomography imaging. Activity of the thalamus, anterior (ACC) and posterior cingulate cortices (PCC), and bilateral angular gyri (AG) show the most consistent associations with the state of consciousness (A = general anesthesia, B = sleep). The same brain structures, which are deactivated when the state of consciousness changes to disconnected in general anesthesia or natural sleep (cool colors in the left columns), are reactivated when regaining a connected state upon emergence from anesthesia (warm colors in the right columns).
