LOW DENSITY ANTIMATTER. “If the density is so low that nucleosynthesis is not possible, low density antimatter domains contain only antiprotons (and positrons).” https://www.mdpi.com/2218-1997/7/9/347/htm View in LinkedIn

CO-EVOLUTION. “Accordingly, food sources, metabolism, endocrine responses, innate immune responses and inflammation co-evolved, and the macrophage is a master cell at the interface between metabolism and immunity. Several lines of evidence suggest that the immune, metabolic and endocrine responses co-evolved.” https://www.nature.com/articles/s41574-018-0059-4 View in LinkedIn

THE TWO BIG ONES. “The most challenging events for an organism’s survival are nutrient deprivation and infection by pathogens; therefore, competition for food and the response to infectious diseases are the main factors that determine the ecological dynamics of populations and species and influence evolution.” https://www.nature.com/articles/s41574-018-0059-4 View in LinkedIn

FRAGMENT FROM NATURE for this weekend focuses on an article titled ‘Inflammaging: a new immune–metabolic viewpoint for age-related diseases.’ For some decades there has been the growing impression that the common pathway of many chronic diseases is inflammation. This article skillfully summarizes the evidence, https://www.nature.com/articles/s41574-018-0059-4 View in LinkedIn

THE OTHER EXISTENTIAL THREAT. “After launching in November, NASA will test its asteroid deflection technology in September 2022 to see how it impacts the motion of a near-Earth asteroid in space.” (Keep calm and carry on). https://lnkd.in/dew7Qkc9 View in LinkedIn

BOUNDARIES. “It should be noted that formation of antimatter domains can be accompanied by domain walls, which either disappear, as it takes place in, or collapse in black holes, leaving gravitational wave background or primordial black holes, which deserve special study in the context of multimessenger probes of the considered scenarios.” https://www.mdpi.com/2218-1997/7/9/347/htm View in LinkedIn

QUANTUM ENTANGLEMENT. “A wide range of animal species are capable of sensing (and, in some cases, extracting directional information from) the geomagnetic field. A strong candidate hypothesis for explaining these phenomena is the radical pair (RP) mechanism (RPM).” (Via Cryptochromes, which occur also in human cells). https://lnkd.in/dThgXrwZ View in LinkedIn

THE ISSUE OF SELF. “Inflammaging is the by-product of the degeneracy of a few receptors that can sense a variety of non-self, self and quasi-self damage signals (or ‘garbage’) and activate the innate immune system.” https://www.nature.com/articles/s41574-018-0059-4 View in LinkedIn
