Although the method of anion resin exchange precipitation has been known since 1960s-1970s, it was only used to synthesize the hydroxides of aluminum, chrome…
Every cell is surrounded by a membrane, which ensures the internal biochemical milieu and regulates the exchange of substances with its surroundings. In every…
All today’s commercial drones use GPS, which works fine above building roofs and in high altitudes. But what, when the drones have to navigate autonomously at…
Their findings, just published in the scientific journal Proceedings of the National Academy of Sciences (PNAS), extend the existing theory that so far was…
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image…
Ball screws or ball screw drives are gear arrangements with rolling balls inserted between a screw and nut element. They are used to translate rotational…
The biologist Dr. Tessa Quax has identified the structure of a central protein used by archaea to determine the direction to swim. Archaea are single-cell life…
Only a few basic geometric shapes lend themselves to covering a surface without overlaps or gaps using uniformly shaped tiles: triangles, rectangles and…
Just as the ability of one nerve cell to signal another depends on how often the cells have communicated in the recent past, the resistance of a memristor…
More than seven years after Pennsylvania officials requested that the disposal of radium-laden fracking wastewater into surface waters be restricted, a new…
Cellulose produced by plants and bacteria is the most important material of biological origin on the planet. Acting as the main component in plant cell walls,…
Humans have 46 chromosomes. These carry the genes and define the genetic material, the so-called genome. So that the number of chromosomes does not double with…
Gene editing is one of the hottest topics in cancer research. A Chinese research team has now developed a gold-nanoparticle-based multifunctional vehicle to…
Researchers previously thought that acoustic tractor beams were fundamentally limited to levitating small objects as all the previous attempts to trap…
Heat power plants (HPPs) supply electrical energy to many cities in the world. The production of heat and electricity starts with burning coal in a combustion…
Charge ordering in mixed-valence compounds, which usually contain positively charged cations in more than one formal charge state, is of crucial importance for…
