Backwashing affects the removal of micropollutants and the dynamic changes in the microbial community in sand filters

Phys.org 

Sand filters are commonly applied in drinking water treatment and can efficiently remove suspended solids, organic matter, and microorganisms from source water. During the process, particulate matter and microbes can attach to filter sands and develop a thick biofilm in both rapid and slow sand filters. To prevent clogging and restore pollutant removal efficiency, backwashing using air, water, or a combination of both is usually required for sand filters.

Type VI secretion systems: Weapons of bacterial destruction

Phys.org 

Bacteria can be quite aggressive. Armed with an impressive array of mechanical and biochemical weapons, they don't mess around when it comes to combating their foes. Notable among these armaments is the Type VI Secretion System (T6SS), a membrane-embedded nanomachine found in many gram-negative bacteria. The needle-like system helps bacteria antagonize prokaryotic and eukaryotic cells by injecting them with harmful proteins (effectors), such as pore-forming toxins and nucleases.

Framework for NASA's Roman spacecraft moves to Goddard clean room

Phys.org 

The primary structure that will serve as the "bones" of NASA's Nancy Grace Roman Space Telescope has moved into the big clean room at NASA's Goddard Space Flight Center in Greenbelt, Maryland. The spacecraft bus, Roman's primary support element, will now be built upon this skeletal framework. When it launches by May 2027, Roman will help unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared astrophysics.

Unraveling the mechanism of green emission peaks in single polyfluorene chains

Phys.org 

Molecular aggregates are clusters of small molecules held together by relatively weak forces believed to be originating from electronic interactions between the molecules. Owing to their exceptional photophysical properties, molecular aggregates find unique applications in many areas of technology and continue to be a subject of intense research. In fact, researchers have utilized molecular aggregates to engineer a variety of functional materials, biomedical tools, and nanodevices.
