A team modified the geometry of flat surfaces to produce a densely packed nanoscale network of pyramidal structures.
Novel engineered surfaces have been created that make many different types of materials resistant to dust, according to aThe structures require no extra energy or resources to prevent dust particles from adhering to surfaces on Earth and in space. Compare that to more active solutions, like antistatic spray or a vacuum that needs fluid or electricity respectively.
While anti-dust technology has been around for a while, it hasn't really taken off outside of the lab due to scale issues. The fabrication techniques utilized in this latest study, known as, print patterns on items more modernly than how mass-produced newspapers and images were made in the 1800s. In tests, the scientists covered their engineered surfaces in lunar dust and then turned each surface on its side. Only 2 percent of the surface remained dusty, as opposed to 35 percent of a similarly smooth surface.Space dust is particularly unpleasant because of how dangerous everything is in that environment. Moreover, the conditions make dust removal difficult. Both the Apollo missions and the Mars rovers have failed due to dust.

Scientists unlock secrets of Earth's wickedly hot innermost realmIn Jules Verne's classic 1864 novel 'Journey to the Center of the Earth,' adventurers descend through an Icelandic volcano into a vast underground world populated by prehistoric creatures as they explore our planet's interior. Researchers on Tuesday said an intensive study of Earth's deep interior, based on the behavior of seismic waves from large earthquakes, confirmed the existence of a distinct structure inside our planet's inner core - a wickedly hot innermost solid ball of iron and nickel about 800 miles (1,350 km) wide. The planet's internal structure comprises four layers: a rocky crust on the outside, then a rocky mantle, an outer core made of magma and a solid inner core.
