Life Engine - Brady Boettcher The Life Engine - Brady Boettcher

Artificial intelligence Explore the ways in which today’s world relies on AI, and ponder how this technology might shape the world of tomorrow The new thermodynamics is also vital for nanotechnology. Much of the original excitement about this field in the 1990s ignored the fact that nanoengines, like proteins, are powered by the energetics of the micro-scale. The science of nanoengines is therefore inseparable from the thermodynamics of microscopic engines. Yet even ignoring for a moment the subtle differences between the macro- and micro-scales, and between the definitions of equilibrium and non-equilibrium, there is one final limitation of 19th-century thermodynamics that is potentially even more significant. But Kelvin’s thermodynamic revolution was only the beginning. Today, new research into the physics of living systems and nanotechnology is challenging the limitations of that 19th-century theory. A century after Kelvin’s death, researchers are creating a second revolution in how we understand the nature of energy. Energy and industry Supercool physics Experiments that probe the exotic behaviour of matter at ultralow temperatures depend on the latest cryogenics technology Business and innovation Find out how recent scientific breakthroughs are driving business innovation and commercial growthScientists are still only feeling their way in the new world of the microscopic engine. But understanding how such engines work, and how they interact to power the nano- and bio-industries, will push Victorian thermodynamics significantly closer to a complete theory of energy and matter. And when we understand how energy is transformed in all processes — from powering a steam locomotive to powering a cell — then perhaps we will be close to a true theory of everything, and one that may be more profound even than an 11D space–time. At a Glance: Kelvin and the new thermodynamics According to his concept, the engine had three banks of four DOHC cylinders; hence it was short like a V8 but taller than a regular V-banked engine. In France, Guy Nègre from Moteurs Guy Nègre worked on a similar machine that saw the light of day in 1989 before being tested privately in an out-dated AGS JH22, chassis. Apart from the W12 configuration, both engines bore no other similarities, nor were there any links between their designers. Life's W12 architecture resembles closely that of the Napier-Lion W12 engine.

Rather, Astumian argued, there are many flavours of equilibrium. For example, in a mechanical sense Bustamante’s stretched RNA is at equilibrium, since at any instant during the motion of the molecule the forces of fluid drag and random Brownian motion are as good as balanced (if they were not, the molecule would be accelerating, which is not the case even for fast stretching). So, in one way these experiments are still investigating equilibrium thermodynamics, and hence can give equilibrium measures. To add a cell the organism first selects a cell it already has in its body, then grows a new cell with a random type in a location adjacent to the selected cell.

Movement and Rotation Physicists are now grappling with the non-equilibrium thermodynamics of the micro-scale, where random fluctuations due to Brownian motion rule The pioneers of thermodynamics developed their laws based on macroscopic systems that they could describe in terms of “average” quantities such as pressure and temperature. This is fine for a typical steam engine, which contains hundreds of litres of steam and is made up of a very large number of molecules. For instance, 22litres of steam contains more than 10 23molecules, which makes average quantities perfectly acceptable since the vagaries of one or two individual molecules are irrelevant.

One example of a “life engine” is the protein kinesin, which is vital for transporting chemicals inside cells. Kinesin transforms chemical energy into motion by binding adenine triphosphate (ATP) — biology’s unique chemical storehouse — in such a way that the protein changes shape, thus enabling it to “walk” along the cell’s scaffolding or cytoskeleton. But cells rely on many other proteins too, from membrane pumps that control the flow of nutrients into the cell to polymerases that physically construct chains of RNA and DNA. All these molecules transform energy to move matter — in other words, all are engines. Revolutions in computing Find out how scientists are exploiting digital technologies to understand online behaviour and drive research progress Offspring can mutate their anatomies in 3 different ways: change a cell, lose a cell, or add a cell. Changing a cell sets a random cell to a random type. Losing a cell removes a random cell. Note that this can result in organisms with "gaps" and cells disconnected from the rest of its body.
