AGING AND INFLAMMATION. "Prolonged exposure to high levels of circulating TNF compromises the integrity of the BBB. Sensitive techniques now detect the “asymptomatic” presence of bacteria in areas previously thought to be sterile...These “immune-tolerated” bacteria may slowly multiply elsewhere until they elicit a chronic inflammatory response." https://lnkd.in/e-V8G86 View in LinkedIn

CHACUN À SON GOÛT. "Taste receptor variants have been associated with differences in taste perception, alcohol consumption, and tobacco use." https://lnkd.in/ewWCUSe View in LinkedIn

MEANING OF SYMMETRY. "Einstein's great advance in 1905 was to put symmetry first, to regard symmetry as the primary feature of nature that constrains the allowable dynamic laws. With the development of quantum mechanics in the 1920s symmetry came to play an even more fundamental role." https://lnkd.in/b-9TDnm View in LinkedIn

SECRET OF TEXTURE. "The secret of nature is symmetry, but much of the texture of the world is due to symmetry breaking." http://www.pnas.org/content/93/25/14256.full View in LinkedIn

"SYMMETRY BREAKING in physics describes a phenomenon where (infinitesimally) small fluctuations acting on a system which is crossing a critical point decide the system's fate, by determining which branch of a bifurcation is taken...such transitions usually bring the system from a symmetric but disorderly state into one or more definite states. Symmetry breaking is supposed to play a major role in pattern formation." https://en.m.wikipedia.org/wiki/Symmetry_breaking View in LinkedIn

SYMMETRY BREAKING AND LACK OF CONSTRAINTS. "The spectrum of electromechanical phenomena on the molecular and nanoscale levels is much richer than in the macroscopic systems owing to symmetry breaking at surfaces and interfaces, the lack of constraints imposed by the lattice in low-dimensional and soft condensed-matter systems, and the absence of macroscopic averaging." https://lnkd.in/efupmXS View in LinkedIn

"SYMMETRY BREAKING is equally important in the world of particle physics. It is really the cornerstone concept out of which the theory of super symmetry was born. Physicists believe that just after the Big Bang, all the forces of nature were identical, and all of the elemental particles were the same. But within an instant, symmetry was broken," creating fragmented forces and particles. https://lnkd.in/bHkyxBh View in LinkedIn

PHASE CHANGES. "The effects of symmetry breaking...phase changes...ice melts to water, or water boils to steam. A phase change is the dramatic change in the internal order of a substance." https://lnkd.in/exUESr6 View in LinkedIn

PHASE TRANSITIONS AND SYMMETRY. "The common feature of phase transitions is spontaneous symmetry breaking." https://lnkd.in/e2CfY5q View in LinkedIn

WATER AND A SNOWFLAKE. "If a system undergoes a phase transit to a more differentiated state, it has more features to describe, and also contains more information. For example, water looks the same from all directions, but when it changes and becomes a snowflake, it becomes more complex. A snowflake crystal looks the same only in six directions. This is an example of symmetry breaking." https://lnkd.in/bHkyxBh View in LinkedIn
