Scientists engineer nanostructured surfaces hostile to bacteria but friendly to cells

Researchers from Tokyo Metropolitan University have created nanostructured alumina surfaces which are strongly antibacterial but can be used to culture cells. They found that anodic porous alumina (APA) surfaces prepared using electrochemistry in concentrated sulfuric acid had unprecedented resistance to bacterial growth, but did not hamper cell cultures. The work is published in the journal Langmuir. The team's technology promises to have a big impact on regenerative medicine, where high quality cell cultures without bacterial contamination may be produced without antibiotics.

A phone screen you can't scratch no matter how many times you drop it; glasses that prevent glare; a windshield that doesn't get dusty. These are all possibilities thanks to a new way to produce sapphire. Researchers at The University of Texas at Austin have discovered techniques to bestow superpowers upon sapphire, a material that most of us think of as just a pretty jewel. But sapphire is seen as a critical material across many different areas, from defense to consumer electronics to next-generation windows, because it's nearly impossible to scratch.

For polychaete day, here's a previous annelid post but edited to only have the polychaetes, some fun facts for you! :)

Sea mouse!

This luminous polychaete worm lives several thousand meters deep on the ocean floor, and sports these extremely light-reflecting scales! Each one is hollow and lined inside with hexagonal cylinders which reflect nearly 100% of the light that hits them. The sea mouse's quill-scales create the only documented case of a "complete spectrum photonic crystal" in an organism, that is, a nanostructure that alters the light entering them and can create the whole spectrum of light. It is thought that the quill-scales are so light reflective as to deter predators or to make the sea mouse's silhouette harder to see.

Bone-eating worms!

Come on tumblr, you love whalefalls, right? These worms are an important part of the whalefall ecosystem, boring into the bones with acid to feed on them! These peculiar animals lack a stomach and a mouth, instead relying on symbiotic bacteria that break down the bone material, after which they suck up the nutrients with "roots"! The red things you see above are the female worms' gills, as the males are in fact microscopic and live inside the females. These worms are valuable in returning every bit of nutrients back into the biochemical cycle!

Pompeii worm!

This deep sea worm is an extremophile if you've ever seen one, it also inhabits hydrothermal vents. They build a tube around themselves and seemingly shield themselves from the elements inside the tube with the help of a "fluffy" coat of sulfur-eating bacteria. What makes them especially fascinating is that their tail end comes to contact with temperatures of up to 80 °C (176°F) while their gills collect oxygen from the outside water that's only 22 °C (72°F)! 60 degrees Celsius of temperature difference to an animal only 13 cm in length, that's bonkers!

Gossamer worms!

These free-swimming polychaetes produce a yellow bioluminescent glow from the appendages at the sides of their body, which is unusual among animals! Gossamer worms have a unique style of swimming from other polychaetes, as they lack many bristles at the ends of their appendages and also the mesenteries in between each body segment. Still they swim, with great flexibility, speed, and maneuverability! It turns out that they retract and extend each appendage to cause differences in drag, causing a wave to undulate through the whole body, which in turn makes their thrust power even stronger. They might serve as inspiration for aquatic robots in the future!

New computational methodology to predict the complex formation of interesting nanostructures

Researchers from the group of Prof. Carles Bo at the Institute of Chemical Research of Catalonia (ICIQ-CERCA) have described a computational methodology that simulates complex processes involving different chemical species and diverse conditions. These processes lead to the formation of nanostructures called polyoxometalates (POMs), with important applications in catalysis, energy storage, biology and medicine. The work appears in Chemical Science. "Our group has recently developed unique methods to study the chemistry of polyoxometalates in solution, their speciation and formation mechanisms. This research has the potential to discover the experimental conditions needed to make new materials," explains Prof. Bo.

Karrakin Archives // HouseStone/MinorFrostfounder/CaelanIV_7565SR

Title(s), Name: Lord Caelan Frostfounder, First Prospector, Hero of Production, Fourth in his Name

DOB: Gneiss ~2, 7565 SR / 24 Throne Karrakis years ago / 4992 u

POB: Un Secunda VI, Un Secunda

Title Notes: "First Prospector" - title of the heir apparent of house Frostfounder; "Hero of Production" - title traditionally held by the ruling family, awarded only after taking the life of a rebel attempting any stop work action; "Fourth in his Name" - Fourth in house records to hold that name, expectation to outdo previous holders

Family History: Frostfounders ennobled in 5750 SR for services to the House of Stone during a period of intense planetary discontent. Charged with the maintenance and expansion of industry in cisplanetary space and lunar partners. Year over year the Frostfounders have diligently worked for the expansion and strength of House Stone. Judged of high loyalty to the Hagiographic cause and philosophy; many Stone forces have records of Frostfounders comporting themselves with the highest honor in combat.

Family Philosophy: Favoring a "first citizen" approach usually only seen among republican minor houses, Frostfounder stresses leadership from the front lines. Scions of the house not destined for the title of First Engineer are given positions in direct mine and industrial management - even the First Prospector is expected to participate in day to day management and protection of industrial assets over the course of their education. Very much in line with House Stone on subjects of worker discipline, Un Secunde VI has never seen a successful work disruption since the ennobling of the Frostfounders

Notes: A striking feature of the Frostfounders is their heavy use of augmentations from an extremely young age; this reflects a similar practice among the ignobles of their planet. Un Secunda VI has been left largely unaltered due to its' rare, delicate natural resources (see: Un Secunda VI general entry, subsection "naturally accruing carbon nanostructures"). As such, the local population opted for augmentations to survive the extreme cold found in the local biomes - primarily taking on characteristics of polar and tundra region lifeforms in order to operate day to day without the use of heavy environment suits.
