ETHER NOT GLYCEROL MEMBRANES. "The membrane structure unique to Archaea plays a significant role in their survival as a barrier between the cytoplasm and the hostile environments. Archaeal membranes are composed of isoprenoid alcohols ether-linked to glycerol, instead of the usual Eukaryotic and Prokaryotic fatty acids which are ester-linked to glycerol." https://lnkd.in/dz9R9uY View in LinkedIn

HOT ACID NICHE. "F. acidarmanus is a champion extremophile. It is a common, and in some cases, the dominant organism in pyrite ore bodies and associated mine tailings and sub-aqueous slime streamer communities in 35–50°C, pH 0–1 solutions with approximately molar concentrations of metals and sulfate.""

MEMBRANE MONOLAYER. "Analyses of the related extreme acidophile F. acidiphilum confirmed that its membranes are also dominated by tetraethers rather than diethers. We propose that a membrane monolayer is a key characteristic that enables archaea to live in acid."" "" " View in LinkedIn

DNA STABILIZATION. "Thermal resistance of the DNA double helix appears to be improved in hyperthermophiles by reverse gyrase, a unique type I DNA topoisomerase that causes positive supertwists for stabilization. The secondary structure of ribonucleic acids appears to be stabilized against thermal destruction by an increased content of GC base pairs within the stem areas and by post-transcriptional modification." https://lnkd.in/dk75SNX View in LinkedIn

"4D PRINTING is fundamentally 3D printing with the added capability of materials transforming over time." https://lnkd.in/dirgGK8 View in LinkedIn

TRANSFORMING MATERIALS. "What if you could train or, more precisely, program a material like wood, carbon or rubber to virtually complete the manufacturing process of whatever object it is destined to become? And what if the material continued transforming, adapting to its function or various functions?" https://lnkd.in/dpEq-ym View in LinkedIn

SENSATE MATERIALS. "The Self-Assembly Lab at MIT has developed a method for programming materials such as hybrid plastics, wood grains, textiles, and carbon fiber to adjust their property and shape in response to anticipated conditions like an increase in temperature, pressure, or moisture." https://lnkd.in/dpEq-ym View in LinkedIn

MULTIPURPOSE MATERIALS. "A product made from programmed wood grains, for example, could be shipped flat and then programmed to transform into its ultimate shape–a bookshelf or a chair, for instance." https://lnkd.in/dpEq-ym View in LinkedIn

4D PRINTING. "What if things could be made to have a kind of memory, allowing it to transform, assemble or replicate itself? Or even repair themselves, adapting to various functions, over time." https://lnkd.in/d7VC6uu View in LinkedIn

EMBEDDED CODE. "The fourth dimension in this experimental manufacturing process is inserted via a customized “code” that is embedded into the 3D printed material. These predefined instructions are dependent upon the object’s constructed geometry, and would also predictably dictate the direction, the iterations and the angles of its transformation, and is activated only when certain environmental conditions change." https://lnkd.in/d7VC6uu View in LinkedIn
