Did Mars once have a full magnetic field in its ancient past like Earth does today, or was it lopsided and only covered one-half of the planet? This is wha | Space
The study notes, “These findings underscore the complexity of Europa’s plume activity. Our results provide a framework to explore various plume characteristics, including gas drag, particle size, initial ejection velocities, and gas production rates, and the resulting plume morphologies and deposition outcomes.”
How do the water vapor plumes on Jupiter’s icy moon, Europa, contribute to the interaction between the moon’s surface and subsurface environments? This is what a recent study published in The Planetary Science Journal hopes to address as a team of researchers investigated how gas drag could influence the direction of particles being emitted by Europa’s water vapor plumes, specifically regarding where they land on the surface, either near the plumes or farther out. This study has the potential to help scientists better understand the surface-subsurface interactions on Europa and what this could mean for finding life as we know it.

For the study, the researchers used a series of computer models to simulate how the speed and direction of dust particles emitted from the plumes could be influenced by a process called gas drag, which could decrease the speed and direction of dust particles exiting the plumes. In the end, the researchers found that gas drag greatly influences dust behavior, with smaller dust particles ranging in size from 0.001 to 0.1 micrometers becoming more spread out after eruption and larger dust particles ranging in size from 0.1 to 10 micrometers landing near the plume sites.

Cases of patients who recovered from trauma after dreaming under surgical anesthesia spur Stanford Medicine researchers to investigate dreaming as therapy.
A new study by Brown University researchers suggests that gold nanoparticles—microscopic bits of gold thousands of times thinner than a human hair—might one day be used to help restore vision in people with macular degeneration and other retinal disorders.
In a study published in the journal ACS Nano, the research team showed that nanoparticles injected into the retina can successfully stimulate the visual system and restore vision in mice with retinal disorders. The findings suggest that a new type of visual prosthesis system in which nanoparticles, used in combination with a small laser device worn in a pair of glasses or goggles, might one day help people with retinal disorders to see again.
“This is a new type of retinal prosthesis that has the potential to restore vision lost to retinal degeneration without requiring any kind of complicated surgery or genetic modification,” said Jiarui Nie, a postdoctoral researcher at the National Institutes of Health who led the research while completing her Ph.D. at Brown. “We believe this technique could potentially transform treatment paradigms for retinal degenerative conditions.”
