The term "Brownian motor" was originally invented by Swiss theoretical physicist Peter Hänggi in 1995. [3] The Brownian motor, like the phenomenon of Brownian motion that underpinned its underlying theory, was also named after 19th century Scottish botanist Robert Brown, who, while looking through a microscope at pollen of the plant Clarkia pulchella immersed in water, famously described the ...
The first example of an artificial molecular machine (AMM) was reported in 1994, featuring a rotaxane with a ring and two different possible binding sites. In 2016 the Nobel Prize in Chemistry was awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart, and Bernard L. Feringa for the design and synthesis of molecular machines.
Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...
In a new book, molecular biologist Venki Ramakrishnan raises critical questions about the societal, political and ethical costs of attempts to live forever.
The 2045 Initiative has a roadmap for developing cybernetic immortality. [8] The Initiative has the goal for an avatar controlled by a "brain-computer" interface to be developed between 2015 and 2020, between 2020 and 2025 creating an autonomous life-support system for the human brain linked to a robot, between 2030 and 2035 creating a computer model of the brain and human consciousness with ...

A molecular demon or biological molecular machine is a biological macromolecule that resembles and seems to have the same properties as Maxwell's demon. These macromolecules gather information in order to recognize their substrate or ligand within a myriad of other molecules floating in the intracellular or extracellular plasm.
"The Incredible Shrinking World of Eric Drexler": Red Herring Interview by Anthony B. Perkins August 1, 1995 "The Incredible Shrinking Man: K. Eric Drexler was the godfather of nanotechnology. But the MIT prodigy who dreamed up molecular machines was shoved aside by big science - and now he's an industry outcast."
