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).

Al-Shaar et al. found that greater intakes of total, unprocessed, and processed red meat were each associated with a higher risk of coronary heart disease. Compared with total, unprocessed, or processed red meat, other dietary components such as soy, nuts, and legumes were associated with a lower risk of coronary heart disease. These associations were stronger among older men. These findings are consistent with the effects of these foods on low density lipoprotein cholesterol levels and support a health benefit of limiting red meat consumption and replacement with plant protein sources; this would also have important environmental benefits. The team also found that substituting whole grains or dairy products for total red meat and substituting eggs for processed red meat were also associated with a lower coronary heart disease risk.
