A new look at proteins in living cells

Posted

(Phys.org)—Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers – early warning beacons announcing the pre-symptomatic presence of cancers and other diseases.

(Phys.org)—Meandering along the water-filled highways laced through an alternative membrane for fuel cells, protons visit sulfur and oxygen atom clusters along the way, according to scientists at Pacific Northwest National Laboratory. The highways are lined with identical hook-shaped molecules. Each channel contains a shell that keeps the water in, formed by the molecules' backbones. The small clusters, known as sulfonate groups, dangle inside the channel. In the middle is a thin "wire" of water.

Studies have found that it is difficult to keep weight off in the long term. For post-menopausal women, natural declines in energy expenditure could make long-term weight loss even more challenging. A new study finds that in post-menopausal women, some behaviors related to weight loss in the short term are not effective or sustainable for the long term. Interventions targeting these behaviors could improve long-term obesity treatment outcomes.
