Estuaries — where freshwater rivers meet the salty sea — are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, “blue” osmotic energy. Researchers in ACS Energy Letters report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.

Perinatal transmission of HIV to newborns is associated with serious cognitive deficits as children grow older, according to a detailed analysis of 35 studies conducted by Georgetown University Medical Center neuroscientists. The finding helps pinpoint the geographic regions and factors that may be important for brain development outcomes related to perinatal HIV infection: mother-to-child HIV transmission during pregnancy, labor and delivery, or breastfeeding.

In Applied Physics Letters, researchers use laser treatments to transform ordinary cork into a powerful tool for treating oil spills. They tested variations of a fast-pulsing laser treatment, closely examining the nanoscopic structural changes and measuring the ratio of oxygen and carbon in the material, changes in the angles with which water and oil contact the surface, and the material’s light wave absorption, reflection, and emission across the spectrum to determine its durability after multiple cycles of warming and cooling.

Researchers in the College of Engineering explore a cancer immunotherapy treatment that involves activating the immune cells in the body and reprogramming them to attack and destroy cancer cells. This therapeutic method frequently uses cytokines, small protein molecules that act as intercellular biochemical messengers and are released by the body's immune cells to coordinate their response.
